Acrylic transliteration from English Acrylic, Acrylic acrylic and methacrylic known chemicals. Include monomers, plates, pellets, resins and composites, acrylic acid methyl ester monomers from methyl (MMA) polymerization, i.e., polymethyl methacrylate (PMMA) sheet plexiglass, "glass" derived from the trade name "Oroglas" (one kind of PMMA board), taken from the "Organic Glass" (ie PMMA). Acrylic Acrylic transliteration from English, Acrylic acrylic and methacrylic known chemicals. Include monomers, plates, pellets, resins and composites, acrylic sheet by methyl enoic acid methyl ester monomer (MMA) polymerization, i.e., polymethyl methacrylate (PMMA) sheet plexiglass, "Organic Glass "from the trade name" Oroglas "(one kind of PMMA board), taken from the" Organic Glass "(ie PMMA). Acrylic sheet production process by casting plate and extrusion plate divided into two categories. Cast acrylic board: high molecular weight, excellent stiffness, strength and excellent chemical resistance. This feature is a small batch processing sheet has unmatched flexibility in color and surface texture effect of the system, and the product specifications for a variety of special purpose. Acrylic sheet extrusion: Compared with casting plate, the lower extrusion plate molecular weight, mechanical properties weaker. However, this feature is conducive to bending and thermoforming process, in dealing with the larger size of the plate, is conducive to rapid vacuum forming. Meanwhile, out of the plate thickness tolerances smaller than the cast plate. Because crowded board is a high volume automated production, adjust color and size of inconvenience, so the diversity of product specifications are subject to certain restrictions. Acrylic panels Material classification in the country can be divided into three categories: First, import plate; two Taiwan-funded board; three are homemade board. They differ on the origin and (MMA) purity of the raw materials used. This is also the key to the quality and price of the decision sheet. Domestic and imported acrylic board has Japan's Mitsubishi (Mitsubishi Chemical) and Germany Degussa two brands. The so-called Taiwan-funded board refers to the British Lucite plate (MMA) for pure raw materials and Taiwan technology, process made. The production of sheet metal molds used in manufacturing most of the United Kingdom and Germany. Produce uniform color acrylic panels, water marks, thin small error; common on the market: Huashuai special, Ruichang, Shenmei, thousands of colors, Osaki Jin and other brands, its Chinese Shuai special brand recognition in the market a high degree, the market price (which is as oil prices rise and fall and float) in the 26-28 yuan / kg; there are some brands such as Tomson, a sub, Green River, New Shun other brands, are also called Taiwan-funded board, but with a new raw material MMA, the quality is also good. The market price of 20-24 yuan / kg. After use effect on Cai Yun tablet is quite good. Domestic plate refers to a raw material used in the production of sheet metal is made in China, and the other is the secondary processing of various acrylic sheet recycling material (PMMA) were generated. But the drawback is obvious surface water marks, thickness uneven, yellowing, suitable for plastic molding, only applies to carving. The advantage is the low price. Through experiments on Cai Yun tablet proof. Spray effect and import a certain gap. 1, colorless, transparent plexiglass plate excellent transparency, light transmission rate of more than 92% 2, excellent weather resistance Adaptable to the natural environment, even a long time in sunlight, wind and rain will not make performance change, good anti-aging properties, can also be safe to use in outdoor 3, good processing properties both for mechanical processing and easily thermal molded 4, excellent performance acrylic plate variety, rich colors, and has a very excellent performance , provides designers with a variety of options, acrylic sheet can be dyed, the surface can be painted, silk or vacuum coating 5, non-toxic, even with long-term exposure of people are harmless, there are gases produced during combustion does not produce toxic gases 6, the linear expansion coefficient of cast plate is approximately 7x10-5m / mK.
