Resin is the main raw material for making plastics, and it is also used for making coatings (the main film-forming substances of coatings, such as alkyd resin, acrylic resin and synthetic fatty acid resin, are mostly found in the Yangtze River Delta and the Pearl River Delta, and are also relatively prosperous areas in the coating industry, such as Changxing Chemical, Newpace Resin, Sanying Resin and DSM Syngenta Resin. ), adhesives, insulating materials, etc. Synthetic resin is widely used in industrial production to separate impurities in liquid.
Acrylic, whose chemical name is polymethyl methacrylate, is an important plastic polymer material developed earlier. It has good transparency, chemical stability, weather resistance, easy dyeing, easy processing and aesthetics, and is widely used in the construction industry.
Acrylic products include acrylic board, acrylic plastic particles, acrylic light boxes, signboards, acrylic bathtubs, acrylic artificial marble, acrylic resin, acrylic (latex) paint, acrylic adhesive and other products, and there are many kinds.
What is acrylic? Acrylic is the best new material for making sanitary ware after ceramics. As a special plexiglass, acrylic can also be used for airplane windshields, which have been used in harsh environments for decades.
Compared with traditional ceramic materials, acrylic has the following advantages in addition to unparalleled high brightness: good toughness and not easy to be damaged; Strong recovery, as long as you dip in soft foam toothpaste, you can wipe the sanitary ware; Soft texture, no icy feeling in winter; Bright colors can satisfy the individual pursuit of different tastes. The basin, bathtub and toilet made of acrylic are not only exquisite and durable, but also environmentally friendly, and their radiation level is almost the same as that of human bones. Acrylic bathroom first appeared in the United States, and now it has occupied more than 70% of the entire international market. In China, Sichuan Dongfang Sanitary Ware Factory took the lead in introducing this technology from abroad and applied for a registered patent in China. Now, domestic acrylic sanitary ware brands such as "Emperor" and "Jazz" are also favored by more and more consumers.
Due to the difficulty and high cost of acrylic production, there are many low-quality and low-cost substitutes on the market. These substitutes, also called "acrylic", are actually ordinary organic boards or composite boards (also called sandwich boards). Ordinary plexiglass plate is cast with ordinary plexiglass cracking material and pigment, which has low surface hardness and is easy to fade, and the polishing effect is poor after polishing with fine sand. The composite board has only a thin layer of acrylic with ABS plastic in the middle, which is easy to be layered due to thermal expansion and cold contraction in use. True and false acrylic can be identified from the subtle color difference and polishing effect of the plate section.
What is acrylic? Acrylic character, also known as acrylic luminous character, is composed of acrylic board and LED lamp. Propylene characters are classified according to their shapes. There are three names in the standard: 1, flat drum character 2, sharp drum character 3 and round drum character. Other shapes are basically evolved from these three. For example, a pointed drum can evolve into a diamond, and a round drum can evolve into an arc, but the choice of knives and the depth of knives are different, and the shapes of characters are completely different.
The production and requirements of flat drum characters;
Draw the required words on the density board with carbon paper, leaving 5cm on each side, install the corresponding straight knife with a manual engraving machine, and open the mold along the outside lines (inside lines and other outside lines) of the words. After the mold is opened, flatten the mold with a file. Then use a file and sandpaper to polish the edges and corners of the convex and concave die of the word into circular arcs, which must be smooth and uniform. Finally, smooth it with sandpaper. You can also use a computer engraving machine.
The production and requirements of sharp drum characters;
Step 1: the method of making flat drum characters is the same as that of making flat drum characters, except that the edges and corners are not ground into arcs for the time being. Step 2: Heightening molding: According to the size of characters and the width of strokes (the widest pen has high cost performance), draw a middle line from the second floor to see if the inclination of both sides is at a right angle of 90 degrees, and use this angle to locate the heightening thickness. Then choose a suitable 45-degree bevel cutter and install it on the multi-function milling machine, literally open the sharp drum downwards, and use 502 glue or three-second glue to drop glue on all parts of the sharp point to make it harder and not pressed.
What is acrylic pigment? Acrylic acid is a kind of skin dye in Taiwan Province province. There may be other names in China. But I just can't find it. I asked "Dechang" in Taiwan Province Province and said that I would not buy acrylic acid and alcohol dyes for the time being.
What do you want this paint for?
Propylene is a hard pigment, which can't be dyed, but it can draw things. T-shirts can also be painted with bright colors, but they will break if they are folded too much; Therefore, it is best to use Mali textile pigments produced in Shanghai to color textiles. Although the color is not as bright as propylene, it is durable. It feels softer, too.
Besides, these are all water-based pigments. So your use depends on whether you need water-based pigments or oily pigments, which is very different.
Cross-linked acrylic acid (what is cross-linked acrylic board) Methyl methacrylate (PMMA) is the most transparent plastic at present. Its proportion is less than half that of ordinary inorganic glass, but its crushing resistance is several times higher, and its other mechanical strength and electrical properties are also quite good, so it is widely used in various departments of the national economy. However, its low temperature resistance, poor surface wear resistance, crack resistance, linear expansion stability and radiation resistance can not meet the growing scientific and technological needs and need to be improved urgently.
Crosslinking is a common method of polymer modification, which can greatly improve the properties of acrylic products.
What is the silk screen printing of acrylic panel? It is to print pictures or words at designated positions on the acrylic that has been shaped.
Help acrylic transfer printing. What kind of resin has good adhesion to acrylic? UV resin is enough for UV glue. No problem at all, the fastest efficiency. There are many kinds of UV resins. You can buy the best adhesion.
What does acrylic blister mean? The acrylic board is heated and placed on the mold, and then sucked on the plastic suction machine. After sucking, it will become the shape of a word, then remove the edge, make a word shell according to the shape of the word, and then install led lights or other lights in the word shell, so that the word can glow internally when connected to the power supply. The words made in this way are called acrylic plastic-absorbing inner luminous words.
What should I pay attention to when using acrylic resin? 1) Pay attention to avoid scratches and breakage.
In plastics, the surface hardness of acrylic resin is high, but it is almost the same as that of aluminum, so attention should be paid to avoid scratching when using it. If you hit the sharp part of the metal hard and drag it, even if it is repaired, there will be traces and optical distortion.
2) Pay attention to avoid being corroded by solvents.
When the surface of acrylic resin is corroded by solvent, it sometimes cracks (surface microcracks). Especially when it comes into contact with a large number of aromatic solvents containing toluene, various quick-drying diluents, esters such as ethyl acetate and ketone solvents such as acetone, it is easy to crack, and sometimes it will produce large cracks. Almost all solvents such as paints, coating agents, adhesives and various primers contain these solvents, so care should be taken to avoid direct contact with acrylic resin. In addition, if you are exposed to volatile gases of these solvents for a long time, sometimes cracks will occur.
3) Pay attention to avoid heating.
Acrylic resin will deform when heated above 100℃. Please do not put it in an environment above 80℃. Please pay full attention to avoid contact with welding sparks, cigarette butts and kindling in construction projects, or being illuminated by lighting lamps, especially spotlights, when taking photos or videos.
4) Matters needing attention in cleaning process
When dust, garbage and oil layer are attached to the surface of acrylic resin, the cleaning method is to gently wipe it with soft cloth, flannel and sponge dipped in water. At this point, dust and garbage may contain hard foreign objects, so it is recommended to brush them off gently before wiping them. It is suggested that warm water and neutral detergent be used to wipe the dirt that is difficult to remove, such as oil layer. Some neutral detergents contain solvents, please make sure that they do not contain solvents before use. For dirt that is difficult to remove, such as adhesive tape, cracks may occur if solvents such as toluene are used. Please do not use it. In addition, scrape with a scraper. , will cause scratches and should be avoided. The longer the adhesive tape, especially the paper adhesive tape, the more difficult it is to remove. Please pay attention to avoid sticking to the surface. Under normal circumstances, the residual glue can be removed by wiping with a soft cloth dipped in warm water. When it sticks tightly, please apply plastic cleaner on the cloth and gently wipe the surface to remove it.
What is the word PVC, acrylic and VI design? Acrylic is a transliteration of English Acrylics. People often say that acrylic board is methyl methacrylate (PMMA) board, which is polymerized from methyl methacrylate monomer (MMA). Features and advantages of acrylic board: the transmittance of acrylic board is as high as 92%, which is known as "plastic crystal". Moreover, it has excellent weather resistance, especially for outdoor use, ranking first among other plastics, with good surface hardness and luster, soft light and great processing plasticity, and can be made into various needed shapes and products.
