Artificial stone: cheap and soft; Disadvantages: the material is soft, easy to scratch, and the leakage resistance is not good, easy to mold, easy to be polluted, its fire resistance is not high, and the resin content is high.
Quartz stone (Quartz stone is actually an artificial stone. . . ): not easy to scratch, the main component is quartz sand (silica) 95%. Its minerals are hard, and its Mohs hardness is 7.5, which is equivalent to that of diamonds. It is not easy to scratch, and it has a certain sterilization and disinfection effect. Metal objects can't be scraped and are not easy to pollute. Quartz stone is produced in vacuum, and both inside and outside are new composite density non-perforated plates. Its surface has corrosion resistance, such as stains or yellowing on the surface. It can be removed with detergent or cleaning towel. In daily cleaning, simply clean with water. Not easy to burn. Quartz stone has a high degree of high temperature resistance, and its fire resistance point is about 1300 degrees Celsius. 93% of its stone has complete flame retardancy and high temperature resistance, and food poisoning will not occur because of stone firing.
Quartz stone: it is a new technology artificial stone synthesized from high-quality quartz stone, and its manufacturing process is produced by a set of most advanced patented BRETONESTONESYSTEM. This product contains more than 90% natural quartz stone or Shi Gang, combined with ultra-high performance resin and special pigment. Its main material is timely, quartz stone has no radiation and high hardness, which makes the quartz stone countertop scratch-free (Mohs hardness 7), pollution-free (vacuum-made, dense and non-porous) and non-burning (timely material). Resistant to 1300℃) high temperature, not old (30 polishing processes need no maintenance), non-toxic and non-radiation (NSF certification, no heavy metals, direct contact with food). Quartz stone countertops have various colors, and Gobi series, crystal series, granite series and shining star series are more distinctive. It can be widely used in public buildings (hotels, restaurants, banks, hospitals, exhibitions, laboratories, etc.). ) and home decoration (kitchen countertops, washstands, kitchen walls, dining tables, coffee tables, window sills, door covers, etc.). This is a kind of non-radioactive pollution.
Artificial stone is made of unsaturated polyester resin as binder, and marble silt or granite fragments are bonded with binder. Ordinary Shi Gang, also known as artificial marble. There are two modes of production: plate production and waste production, both of which have their own advantages and disadvantages. The former is superior in diagonal and flatness, while the latter has better color uniformity, and can also be used for special-shaped processing, such as cylindrical processing. At present, there are many production methods of stone in the market. Product features: ① Organic pigments of different colors are mainly used in Shi Gang. Organic pigments have no tolerance to sunlight, moisture, acid and alkali, and are easy to fade or even change color. (2) The high content of glue in most stone columns, on the one hand, leads to the weak texture of stone materials, and the decorative effect cannot be upgraded; On the other hand, glue expands with heat and contracts with cold, so the product is easy to deform and warp, and its service life is short; Moreover, its glue generally contains volatile toxic gases, which is harmful to human body. (3) Due to technological reasons, Shi Gang has many pores, and the product has poor impact resistance, easy leakage and discoloration, and poor anti-pathological ability. Its gloss is fake, and it is easy to wear and tear, and it is not durable. ④ Shi Gang made of marble powder is not acid-resistant, because its main component is CaCO3, which is easy to react and decompose with acid; The hardness of marble powder and binder is very low, so the hardness of Shi Gang is also very low, generally less than Mohs hardness 3, so it is not wear-resistant, scratch-resistant and easy to scratch. ⑤ The first generation Shi Gang was more or less radioactive because it contained marble and granite. Artificial stone is mainly used for interior walls and floors, and its physical properties are not as good as natural stone and quartz stone. When used on the floor, it is easy to bulge, change color and scratch, and it is extremely difficult to clean after long-term use. There is also a big gap between the surface gloss and natural stone.
Artificial quartz stone:
Advantages: Artificial stone is more wear-resistant, acid-resistant, high temperature-resistant, and has strong functions of impact resistance, compression resistance, bending resistance and permeability resistance. The treatment of deformation, adhesion, turning and other parts is original; Because there are no pores on the surface, oil and water stains are not easy to penetrate into them, so the anti-pollution ability is strong; It can be bonded seamlessly at any length, and two pieces are bonded and polished with the same adhesive, which is seamless. Especially in recent years, the newly popular artificial quartz stone countertops have better performance than ordinary artificial marble and engineering columns, and are more suitable for countertops.
Missing point: Artificial stones made of different materials have different disadvantages. Generally, try to choose artificial stone containing acrylic, which has strong hardness and good toughness. Special note: even seamless artificial stone will have certain differences in quality due to different processing technologies, so we must choose a brand with good reputation and guaranteed service.
Marble countertop: The length of natural stone can not be too long, nor can it be made into a whole countertop, which is not suitable for the modern trend of pursuing a whole countertop.
Advantages: the texture of natural stone is very beautiful, the texture is hard, the scratch resistance is very prominent, and the wear resistance is good; Low cost, different colors, and the most commonly used price are also reasonable. It is an economical and practical countertop material. There are also high-grade natural stone countertops, which are suitable for people who pursue high taste.
Missing points: the two spliced pieces can not be integrated, and the gap is easy to breed bacteria; Natural stone has a high density and needs strong cabinet support. Although hard enough, it is not elastic enough. If it is violently hit, it will produce cracks and it is difficult to repair. Some invisible natural cracks will also break when the temperature changes sharply. Natural stone also has radiation, which has certain adverse effects on the environment.
