Microcrystalline is a new decorative building material, in which composite microcrystal is called glass-ceramic composite plate, which is a high-tech product with a layer of 3-5 mm glass-ceramic on the surface of ceramic glass fossils and fully integrated after secondary sintering.
The thickness of microcrystal is13-18mm, and the glossiness is more than 95.
In the field of building materials, since the former Soviet Union invented the calendering method to prepare glass-ceramics and then Japan invented the sintering method to prepare glass-ceramics building decoration materials, this material has gradually entered the market of high-grade building materials because of its high-grade decorative artistry, excellent mechanical properties, chemical corrosion resistance (weather resistance), wide sources of raw materials and low economic cost. Nowadays, this kind of glass-ceramic building material is known as "high-grade decorative material in 2 1 century"
Micro-spar, known as glass-ceramic composite board in the industry, is a high-tech product in the field of building ceramics. Its characteristics are crystal clear, elegant, natural growth, ever-changing imitation stone texture, colorful layering, ingenious appearance decoration effect, no pollution, easy cleaning, excellent physical and chemical properties and stronger weather resistance than stone.
Early ceramic composite plate microcrystalline stone
Weather resistance is favored by high-end building materials markets at home and abroad.
Glass-ceramics, also known as glass ceramics, is a new multiphase material composed of microcrystalline phase and glass phase. It is different from pure crystal materials and a considerable part of solid materials. Among these materials, the glass phase content is usually very small (a few are more), while the glass phase content in glass ceramics, especially those used for decorative building materials, is more (sometimes as high as 50%). However, it is also very different from pure glass. Under normal circumstances, glass does not contain any crystalline phase, while glass-ceramics contain crystalline phase (mostly micron-sized microcrystalline phase). The biggest difference between microcrystalline phase and glass phase is that the particles of the former are arranged in order, while the particles of the latter are arranged in disorder at a long distance. The former will produce diffraction lines after X-ray irradiation,
Polishing line for producing microcrystalline stone
The latter can't produce diffraction lines.
In view of the fact that glass-ceramic is a multiphase material of microcrystal and glass phase, it has some properties of glass and crystal. Therefore, glass-ceramics concentrate the characteristics of both glass and crystal materials (including ceramic materials). The performance index of this new multiphase material-glass ceramics depends on the type of microcrystalline phase, the size and distribution of crystals, the number and composition of other glass phases and the structure between them. Therefore, glass-ceramics not only have a small thermal expansion coefficient (which can be an excellent thermal shock-resistant material), but also have high hardness and wear-resistant mechanical properties (which can be a high-strength material), and can also have special electrical, thermal, optical, magnetic and biological properties (which can be a functional material). Therefore, glass-ceramics can be used in many fields.
Around 2002, several large manufacturers in Foshan (including Bode, Xinzhongyuan, Jiajun, Oushennuo, etc. ) industrial production has been realized one after another. In the continuous production practice, we gradually overcome (or basically overcome) the defects of the main pores in the first generation of glass-ceramics, and successfully put the products on the market. The landmark events are: in August 2002, the world's first self-developed "Seiko Jade" was born in Bode, and the national invention patent was declared, marking the birth of mainstream microcrystalline stone; The first generation of glass-ceramic composite plate is famous for its white appearance, bright and soft luster, good hardness and wear resistance, and good acid and alkali resistance. However, because its crystals grow inward at the edge of the retained particles, the crystal flowers appear monotonous.
If the glass-ceramic composite plate undergoes glass-ceramization during the firing process
Eurostar microcrystalline stone: jade
In the molten state, the influence of glass-ceramic particle size becomes less important.
These conclusions point out the direction for solving the technical problem of air holes in the first generation of glass-ceramics. For this reason, we introduced a lot of zinc oxide with high surface tension and low viscosity, successfully developed the second generation of glass-ceramics composite plate with wurtzite as microcrystalline phase, and put it into trial production in 2004 ~ 2005. At the same time, it also obtained the national invention patent.
Because the second generation of glass-ceramics has large surface tension and low viscosity, in the melting stage of glass-ceramics sintered by composite plate, the accumulated gaps between the original glass particles gather into larger bubbles and break through the surface. After the bubble bursts, the melt flows back and tears the interface constantly, which provides the lowest energy barrier position conducive to crystal growth and forms a variety of crystal forms, such as flower-like, chrysanthemum-like, radial, flowing, volcanic lava, etc. This reflects the crystallization characteristics of the second-generation glass-ceramics, that is, breaking through the grain boundaries of the first-generation glass-ceramics, and growing beautiful, natural, smooth and changeable crystal patterns again, thus greatly improving the aesthetics of its decorative art. In addition, due to the influence of the surface tension and viscosity of the second-generation glass-ceramics, the entire cross section of the glass-ceramics layer can basically have no gaps, only traces left by residual gas escaping from the surface (such traces will generally be eliminated after polishing). This is in sharp contrast to the first generation of glass-ceramics which left many pores in the cross section. These two characteristics are the advantages of the second generation glass-ceramics. However, the hardness and chemical resistance of the second generation glass-ceramics are lower than those of the first generation glass-ceramics, which is the disadvantage of the second generation glass-ceramics.
Miniature smelting furnace
Since the second half of 2005, the price of 99.5% zinc oxide has risen sharply, from about 6,000 yuan per ton to 28,000 yuan per ton in the first half of 2006. Under the pressure of this economic situation, researchers turned to research and develop new glass ceramics, which are not as cheap as zinc oxide.
At the end of 2006, the third-generation glass-ceramic composite plate with pyroxene as microcrystalline phase was successfully developed, which not only did not add zinc oxide, but also greatly reduced the cost level of the second-generation glass-ceramics, while retaining the characteristics that the second-generation glass-ceramic crystals broke through the grain boundaries, grew different shapes of patterns and sections, and basically had no pores.
After 2009, microcrystal has developed rapidly in China, especially 20 10, 201,20 12, and large ceramic enterprises have joined in the research and development and production of microcrystal series products. Since 20 1 1, a number of enterprises, such as Bode, Jiajun, Dong Peng and Oushennuo, have been exploring microcrystalline technology, and the technology is becoming more mature and the products are more refined. Take 20 1 1 as an example. According to incomplete statistics, in addition to Bode and Jiajun, which mainly produced microcrystalline products earlier, some enterprises mainly engaged in polished tiles and antique tiles have entered the microcrystalline field, such as Dong Peng, Eagle Brand, Kelpolo, Guanzhu, Xinghui, Oushennuo, Bohua, Xinzhongyuan and Maji. In Shandong and other producing areas, fewer enterprises have started to produce microcrystalline stone, and many first-line brands are increasing their investment in microcrystalline stone. In 20 13, a dark horse of Xiangcheng tiles in the United States also rose rapidly and became a new star in the success field, attracting much attention. Therefore, microcrystalline stone is regarded as another market explosion point after polished tiles, antique tiles and other categories.
Microcrystalline, as a new building material, has gradually entered people's families. According to the raw materials and manufacturing process of microcrystals, microcrystals can be divided into three categories: non-porous microcrystals, whole microcrystals and composite microcrystals.
Non-porous stone
Non-porous microcrystalline stone production workshop
Non-porous microcrystal, also known as artificial white marble, is a new type of high-grade environmental protection stone, and many physical and chemical indexes are better than ordinary microcrystal and natural stone. Its biggest feature is no pores, no speckles, high gloss and zero water absorption. It can be polished and renovated, and is suitable for advanced decoration places such as exterior walls, interior walls, floors, columns, washbasins and countertops [1].
Healthy and perfect
All-in-one glass-ceramics, also known as glass-ceramics, is a new high-grade decorative material. It is made of natural inorganic materials by special technology and high temperature sintering. It has the excellent characteristics of no radiation, no water absorption, no corrosion, no oxidation, no fading, no color difference, no deformation, high strength and high luster.
The performance of microcrystalline stone is better than natural granite, marble, artificial stone and artificial marble, which is related to its material composition and molding.
Microcrystallite is a special crystalline phase, which is separated from the glass liquid with special composition by selecting several main components in granite at high temperature. Therefore, it has high hardness and strength, and it is formed by secondary high-temperature melting in the molding process. So there is no texture formed by natural stone, so it is not easy to break, does not absorb water, is not afraid of erosion and pollution, and has high gloss. After decoration, there will be no color difference, alkali flooding, juice spitting and other phenomena. No maintenance required.
In addition, natural stone contains radioactive elements (such as radon, radium, etc.) harmful to human body in different degrees due to the natural formation process. Being in it for a long time will cause dizziness, general weakness, fatigue, infertility and other nameless diseases. In severe cases, there is a potential risk of cancer. After two high-temperature refining and analysis, microcrystalline stone does not contain any radioactive elements.
The coloring of microcrystalline stone is made by using metal oxide as colorant and sintering at high temperature, so it will not fade and its color is bright.
sense of reality
Microcrystalline is a kind of material which is crystallized by firing at a high temperature similar to granite. From the appearance and texture, the surface smoothness of its polished plate is much higher than that of stone (the luminosity can reach 90- 120 gloss unit). More importantly, its special microcrystal structure makes the light incident from any angle and diffuse reflected by tiny microcrystal particles, which can evenly distribute the light to any angle (instead of focusing only on the reflection angle like a mirror), making the board form a soft jade texture, which is more crystal clear and moist than natural stone.
perform
Compared with natural stone, it has more physical and chemical advantages: microcrystalline stone is sintered by a special process at a high temperature similar to granite, with uniform texture, high density, high hardness, better compression resistance, bending resistance and impact resistance than natural stone, durable wear resistance, little damage and no common fine cracks in natural stone.
Quality of materials
The luster of the plate is crystal clear and soft: microcrystalline has a special microcrystalline structure and a special glass matrix structure, and the texture is fine, and the plate is crystal clear and transparent, which can diffuse and diffuse incident light, making people feel soft and harmonious.
colour
The production process of microcrystals can produce a variety of color series according to the needs of use (especially the four color systems of crystal white, beige and light gray hemp are the most fashionable), and at the same time, it can make up for the defect of large color difference of natural stone. The products are widely used in the interior and exterior decoration of hotels, office buildings, railway stations and airports, and are more suitable for the advanced decoration of families, such as walls, floors, decorative boards, furniture, basin boards and so on.
Acid and alkali resistance
As a chemically stable inorganic crystal material, microcrystal also contains a glass matrix structure, which is superior to natural stone in acid, alkali and corrosion resistance, especially in weather resistance, and will not fade or reduce its strength after long-term exposure to wind and sun.
Excellent pollution resistance and convenient cleaning and maintenance.
The water absorption rate of microcrystalline stone is extremely low, almost zero, and various polluted slurries and dyes are not easy to invade and penetrate, and dirt attached to the surface is also easy to remove and wipe, which is especially convenient for the cleaning and maintenance of buildings.
opposite sex
Microsite can be made into various curved surfaces and curved panels required by customers by heating method, with simple process and low cost, which avoids the disadvantages of cutting and polishing in arc stone processing, such as time-consuming, material-consuming and resource-wasting.
Does not contain radiation
The production of microcrystalline stone artificially eliminates any radioactive elements, unlike natural stone, which contains radiation damage to human body. It is the safest green environmental protection material in modern times.
disadvantaged
1. The Mohs hardness of the jade layer on the surface of microcrystalline stone is 5-6, and its strength is 6-7 lower than that of polished brick.
2. The surface gloss of microcrystalline stone is high, up to 90%. If you encounter scratches, it is easy to appear.
3. There are a certain number of pinholes on the surface of microcrystalline stone, which are easy to appear when encountering dirty things.
4. Except for a few high-grade microcrystalline stone floor tiles, most microcrystalline stone floor tiles are difficult to achieve seamless connection of patterns because each pattern is different.
transparency
The optical properties of transparent glass are transparent. It is this characteristic that enterprises fully display the exquisite artistic patterns printed by transparent glass-ceramic printed brick composite board products, and increase the three-dimensional sense and brightness of this pattern.
The optical properties of glass-ceramics range from translucent to opaque, except for a few varieties with very small main microcrystal phase. This is the biggest difference in appearance between glass-ceramics and glass.

Eurostar Microsite: Gem
The artistic pattern of transparent glass-ceramics printed brick composite board is realized on the ceramic tile by modern printing technologies such as screen printing, cots printing and ink-jet printing. The transparent glass covered on the surface only enhances the three-dimensional sense and bright visual effect of these patterns, and plays the role of finishing touch or icing on the cake. The artistic decoration of this product mainly depends on the printed artistic patterns and colors, that is, efforts should be made in plate making, color selection and printing equipment. Judging from the technical level and production capacity of building ceramics industry, the technical threshold for developing and producing this product is relatively low, and the technical content is relatively low. Almost all ceramic factories can produce printed tiles.
The artistic decorative patterns of glass-ceramic composite plates are all realized by the crystal patterns precipitated from glass-ceramics. Relatively speaking, the research, development and production of glass-ceramics that can control and expand the crystallization performance are difficult, with high technical threshold and high technical content. Therefore, the building materials company learned from the channel that so far, no other manufacturer can prepare similar glass-ceramics that can control and expand the crystallization performance except Bode.
inner structure
Transparent glass has a single structure, and the arrangement of its internal constituent particles is disordered, irregular and randomly distributed macroscopically. They don't diffract x-rays, and there will be no diffraction peak on its diffraction curve.
In addition to glass phase, glass-ceramics also contain a certain amount of crystal phase. The arrangement of the constituent particles in these crystalline phases is ordered both macroscopically and microscopically, and these crystals will be diffracted with respect to X-rays.
perform
The properties of transparent glass are mainly influenced by the composition and structure of glass. The properties of glass-ceramics are not only affected by most glass phases, but also by a certain amount of glass-ceramics phases. Due to the influence of microcrystalline phase, the mechanical strength of microcrystalline glass composite board is higher than that of transparent glass printed brick composite board.
Bode Company: Gems
The results show that the fracture modulus and fracture strength of glass-ceramic composite board are greater than that of transparent glass-ceramic printed brick composite board, and the average fracture strength of the former is 6070.5 Newton and the average fracture modulus is 45.4 MPa. The average failure strength of the latter is 4240 Newton, and the average modulus of rupture is 4 1.3 MPa. At the same time, the former has a higher friction coefficient than the latter. This shows that the former has better anti-skid performance than the latter.
It can be concluded that in order to build an excellent brand of microcrystalline stone, enterprises need to forge their competitiveness in the field of microcrystalline stone in addition to their comprehensive strength: first, innovative competition in technology and production technology; Second, the competition of product development and design; Third, the competition between supporting facilities and space design; Fourthly, the marketing of microcrystalline stone competes with terminal service and word of mouth. Whoever can establish a leading competitive advantage in these four aspects will become the ultimate king in the field of microcrystal. Undoubtedly, in today's microcrystalline market, some self-owned enterprises do not have the strength to produce microcrystals, except for corporate brands such as Bode Company, which can develop and win the market with high-quality microcrystals. Opportunism is obviously misleading consumers, and the result is not worth the candle.
manufacturing technique
Manufacturing technology of polished edge of microcrystalline slate
Microcrystalline plate is made of glass particles with specific composition by high temperature sintering, and its internal structure is composed of glass phase and crystal phase. The ratio of two phases determines the physical and chemical properties and surface characteristics of materials.
Manufacturing process of microcrystalline slate
. The inner crystal phase of microcrystals grows from the interface of glass particles to the center. Due to the different crystal growth directions and the existence of two lithofacies structures, gorgeous surface patterns are formed. Because the microcrystals are fired at high temperature, the glass particles are in a molten state at high temperature, and the air existing in the overlapping space between particles and the original bubbles inside the particles are closed and cannot be discharged, thus forming a large number of pores inside. If these pores appear on the surface of microcrystalline stone, they will become surface defects and cause waste products. At the same time, in the molten state, due to the effect of surface tension, a "fire polished" surface layer is formed on its surface, with a thickness of only tens of microns and a gloss of over 70 degrees. This extremely thin surface layer completely covers the internal pores, thus ensuring the decorative effect of the surface of microcrystalline stone. Therefore, this extremely thin surface structure is very important to the surface quality of microcrystalline stone. The unique structure of microcrystalline stone makes it unique in grinding, polishing and cutting, so it is impossible to simply apply the processing technology of natural stone, and the corresponding processing equipment should also adapt to this process change.
The polishing of natural stone has two purposes, one is to obtain the smoothness of the surface, and the other is to obtain the gloss of the surface. However, due to its unique internal and surface structure, the surface flatness of microcrystalline plate must be formed during the sintering process of the plate, and can not be corrected by subsequent grinding, otherwise the surface structure will be destroyed, internal pores will be exposed, and the decorative effect of the plate surface will be seriously affected. Therefore, in the process of polishing, this layer of structure must be completely preserved, so the polishing amount is very small. Therefore, the polishing of microcrystalline stone plate is actually only to obtain the required surface gloss. In addition, due to the temperature change during firing, the surface of the board will not be an ideal plane. Therefore, in the process of grinding and polishing, in order to ensure the uniformity of grinding quantity everywhere on the surface, the abrasive tool must have the following function, that is, the so-called copying function. Therefore, the grinding and polishing process characteristics of microcrystalline stone can be summarized as "profiling shallow grinding" process. This is the uniqueness of natural stone.
Buildings decorated with microcrystalline stone are not only brilliant and luxurious during the day, but also at night. The building decorated with microcrystalline stone on the outer wall is crystal clear, bright and soft, which gives a panoramic view of the colorful and prosperous night scene on the towering street wall. In this pearl world general environment, it clearly shows the incomparable artistic charm of ordinary stone and tile, just like a proud princess.
(1) Flat-fell seam steps ("kicking")
Generally speaking, for 800×800(mm) composite plate microcrystalline brick, the flatness tolerance (maximum allowable deviation) of four sides is (+0.6,-0.5) mm. Because the middle part is convex or concave, in extreme cases, there may be as high as 1. 1mm between two adjacent plates.
Note: the board surface can not be regarded as a part of a simple sphere at all. In this way, the most prominent part of the regular (convex) deformed plate surface is irregularly distributed along the length of 800 sides, and there are not many opportunities to be in the middle symmetrical position. Therefore, even if two bricks with deviations of +0.6 and -0.5 are laid adjacent to each other, the "step" ("kicking") of 1. 1mm may not be formed, which only exists in extreme cases.
The most effective measure is to choose the board surface reasonably and arrange the laying sequence reasonably to avoid the situation that the flatness is obviously positive (convex) and obviously negative (concave) directly meet: if this happens by chance, it must not be tolerated, and the tiles must be replaced immediately to ensure that another tile suitable for this occasion is selected for replacement; In some cases, in fact, as long as the tiles are turned 90 degrees, the flat-fell seam steps may be significantly reduced.
Note: It is an important principle to evaluate the ability of the construction team to consciously implement the above skills of "brick replacement and adjustment".
The worst construction situation is the construction scope of the same area (lobby, corridor, room, etc.). ) adopt two horizontal benchmarks at the same time; At this time, both ends are "opposite" at the same time and paved inward, but we don't pay close attention to whether their respective horizontal benchmarks are consistent. As a result, when the two sides met, we found that there was an obvious systematic "platform collapse step" between the two plates. This seemingly absurd thing happened in Guangzhou: at the end of July 2005, such a problem occurred in a 20-story building in Guangzhou; Strangely, at this time, I will complain about the flatness of our composite board! Fortunately, in the end, facts speak louder than words, and the construction party admitted the mistake. However, if our sales team and sales community are better trained, the quality supervisor of Yue Zhong Company and the quality control technician of Microcrystalline Factory can travel long distances to wash their innocence without a day.
Note: This absurd example shows how good the salesman has the opportunity to improve: the chaotic construction team is not good, but the salesman who is good at dealing with on-site problems will certainly actively expand his business space.
Generally, the maximum allowable deviation of the length and dimension of the slab edge of 600 or 800mm composite slab brick is (+0.5,-0.5) mm. When adopting the construction scheme of close joint (commonly known as "joint"), attention must be paid to eliminating the accumulation of "positive and negative tolerances": otherwise, staggered joints will often occur; In extreme cases, the dislocation of 10 plate may be as large as 10 mm. (2) Flat-fell seam dislocation.
Eurostar microcrystalline stone: decorative effect
The fundamental reason of the above-mentioned flat-fell seam dislocation is that the side length matching of adjacent tiles has not been properly handled. As long as the formal construction procedures are strictly followed, it will not appear at all. The basic point is that we should follow the operation procedure of "elastic line arrangement": mark the control crosshairs perpendicular to each other in the main part of the room to accurately check and control the position of the plates, and each plate should be correctly positioned in the laying grid so specified. When necessary, the panel size should be properly selected to avoid the situation that several panels with large side length deviation are obviously close (+0.5mm) or (-0.5 mm) and closely connected. In some cases, as long as the tiles are turned 90 degrees, the side length matching problem of adjacent tiles can be obviously improved.
(3) pollution of the board surface
Before construction, each side of the composite board should be coated with waterproof coating with coordinated hiding power and color, and a waterproof coating layer with a width of 2 cm should be coated around the bottom surface. After the waterproof coating is dried, it can be used in the project. Otherwise, especially in the case of white microcrystals, once sewage seeps into the gap between the plates, a stain band with a width of 10 ~ 20 mm may appear on both sides: the glass-ceramics still have a certain light transmission ability, thus reflecting the pollution on the side to the surface layer, forming this visible stain band.
The micro-site is particularly bright, and any pollution will be dazzling. Try not to peel off the plastic film on the surface too early and too wide during construction operation, which is both antifouling and moderately scratch-proof.
Production characteristics
Glazing products combine the advantages of polished tiles, antique tiles and ceramic tiles. The product completely releases the implication of glazed tiles' matte and dark light, and solves the defect that semi-polished tiles are easy to hide dirt, which not only has the luster and hardness of polished tiles, but also has the high imitation effect and rich printing effect of glazed tiles.

Compare glazed tiles with other ordinary tiles, and just feel them! The single gloss value of the finished product can be as high as 104 degrees, and the average value is 94 degrees; Touch: You can feel the delicate and smooth texture by touching the glaze. "Nano-alumina" is added to the transparent glaze covered by glazed tiles, which enhances the wear resistance of the surface while maintaining the brightness of the product, which means that the product can be laid at will and used on the walls and floors of all spaces!

Advantages of polished tiles
Polished brick is a kind of bright brick, which is made by polishing the whole brick surface and belongs to a kind of integral brick. Compared with the whole brick, the surface of polished brick is much smoother. Polished tiles are hard and wear-resistant, and are suitable for most indoor spaces except bathrooms and kitchens, such as balconies and exterior wall decoration. Based on the application of flower infiltration technology, polished tiles can make various stone-like and wood-like effects.
Disadvantages of polished tiles
1, polished tiles are loved by consumers because of their high hardness, wear resistance and suitability for large-scale indoor and outdoor paving. However, the concave-convex pores left by polished tiles in the production process will hide evil and shelter evil, making the surface easy to penetrate pollutants, and even some tea leaves will be powerless when they fall on polished tiles. Perhaps the industry is aware of this. Later, some polished tiles with good quality were added with an antifouling layer when they left the factory, but this antifouling layer made the polished tiles lose the effect of a whole brick. If you want to continue to connect the whole body, you have to continue to brush the protective layer. The decoration industry also has the practice of waxing water before construction to prevent sticking. Italy, Spain and other European and American countries are at the forefront in the anti-pollution technology of polished tiles, and only a few first-line brands in China have this anti-pollution technology. Therefore, anti-fouling treatment technology has become a compulsory course for good polished tile products.
Polished tile effect glaze is different from decorative methods such as bleeding and large particles. It uses a special frit to mix with the substrate, and then it is pressed or applied to the surface of ceramic tile through special screen printing. After firing, it is polished to produce decorative effects such as particles or patterns of different colors.
Advantages of glazed tiles
1. Full throw glaze is a kind of glaze with special formula, which can be polished on the glaze surface. The full throw glaze applied to the full throw glaze combines the advantages of polished tiles and antique tiles.
2. Its glaze is characterized by transparency, which does not cover the bottom layer glaze and various flower glazes, and only throws away a thin layer of transparent glaze when throwing glaze. Transparent embossed glaze is an outstanding work of aesthetic ceramic Kelpolo. Its embossed glaze is printed into discontinuous embossed granular glaze on the brick surface by screen printing, which is thrown away after firing, and the effect is more unique.
3. From the technical point of view, there are two main production processes of full-throw glaze. One is the process used by some original glass-ceramics enterprises, which adopts the process of printing first and then glazing. The transparent glaze on the surface is thicker, so it is more stereoscopic, transparent and easy to polish; In addition, because of its thick glaze, it is easy to throw. The other is a process used by the original enterprises that produce antique bricks, that is, the patterns under the glaze and the frits on the surface are printed. This process has high fidelity and low cost, but it is easy to expose the bottom when throwing glaze.
4. As a brand-new production technology, full-throw glaze is not so perfect in terms of materials, equipment and technology, such as wear, dirt absorption and exposed bottom, but the new technology is improved through continuous development and testing.
Disadvantages of glazed tiles
The hardness density of glazed tiles is similar to that of polished tiles. Polished tiles are polished with secondary materials, and the surface is very thick with crystals! Glazed glazed tile surface, very thin, but can be used! Practice has proved that the wear resistance of glazed tiles is not worse than polished tiles, but the pollution prevention effect is far better than polished tiles. Glazed tiles have active patterns, bright colors and more beautiful appearance, and their glossiness and brightness are completely inferior to polished tiles. Polished tiles are super bright!
The popularization rate is low, the technical requirements are high, and the quality is difficult to guarantee.
In the past, the technology and equipment of glazed tiles were not very mature, and they were produced in large quantities in China. This product has appeared in the world for many years, especially in Spain and Italy, but it has not been widely used, mainly due to technical obstacles and previous comparative advantages (compared with polished tiles).
If the glaze is too thick (above 1mm), a large number of bubbles are easily generated during firing, which makes the product have poor antifouling ability and lose luster. However, if the glaze layer is too thin, the glazed tile will always be deformed, and it is easy to leak or partially expose the bottom when polishing. Therefore, it is difficult to ensure the quality of products and the stability of superior products in mass production.
Compare full-throw glaze with other ordinary tiles, and just look and feel! Under the diffuse reflection and irregular refraction of light, the glaze makes the product soft to the touch, bright in color and full and thick in transparency. The single gloss value of the finished product can be as high as 104 degrees, with an average of 94 degrees. Touch: You can feel the delicate and smooth texture by touching the glaze. "Nano-alumina" is added to the transparent glaze covered by glazed tiles, which enhances the wear resistance of the surface while maintaining the brightness of the product, which means that the product can be laid at will and used on the walls and floors of all spaces!
Product trend editing
Conclusion: Although the technological requirements of glazed tiles are strict, according to the industry and market reaction, the future glazed tiles market has a good prospect, gradually maturing and gradually occupying a dominant position in the market, becoming one of the tiles in the building materials market.
Such a comparison will make the price different.
