Acrylic Polishing Compound
Acrylic, also called PMMA or plexiglass, chemical name is polymethyl methacrylate. It is an important plastic polymer with early development. It has good transparency, chemical stability and weather resistance, easy to dye, easy to process, beautiful appearance, and has a wide range of applications in the construction industry. Plexiglass products can usually be divided into pouring plates, extrusion plates and molding plastics.
acrylic polishing compound
A acrylic products acrylic board, acrylic plastic particles, acrylic light boxes, signs, acrylic bathtub, acrylic artificial marble, acrylic resin, acrylic paint (latex), acrylic adhesive and so on many kinds of products.
Processing method of people common to the Department of acrylic products from raw materials, acrylic resin pellets or sheet through a variety of different, and with a variety of different materials and function of spare parts to be assembled of acrylic products. As for the commonly heard acrylic fiber, acrylic cotton, acrylic yarn, acrylic nylon, etc., refers to the artificial fibers made from acrylic acid, and acrylic products are not related.
Among them, people often say that the acrylic plate is Methyl Methacrylate Polymeric (PMMA) plate, which is composed of the methyl methacrylate monomer Methyl Methacrylate (MMA) "polymerization. Or made by extruding acrylic pellets through a plate extruder. Formerly boards are commonly called organic glass. Acrylic comes from English acrylic, which means PMMA board made of organic compound MMA. Its transparency and transmittance are like glass. From all transparent plastic, such as PS, PC, etc., or by the poor recovery of MMA made of sheet metal are collectively referred to as organic glass. In order to distinguish, the high quality pure material MMA is made of PMMA board named acrylic board, so as to distinguish it from the common plexiglass plate.
1, with crystal like transparency, light transmittance of more than 92%, soft light, clear vision, dye stained acrylic has a very good color rendering effect.
2 、 acrylic board has excellent weatherability, high surface hardness and surface gloss, as well as better high temperature performance.
3, acrylic plate has good processing performance, can use hot forming, or can also be processed by mechanical way.
4, transparent acrylic plate with comparable glass transmittance, but the density is only half of the glass. Moreover, it is not as brittle as glass, and even when it is broken, it does not form sharp fragments like glass.
5, acrylic plate wear resistance and aluminum close, good stability, resistance to a variety of chemical corrosion.
6 、 acrylic board has a good printability and spray, using appropriate printing and spraying process, can give acrylic products ideal surface decoration effect.
7, flammability: non spontaneous combustion, but flammable, does not have self extinguishing.
Hardness is one of the most important parameters of the production process and technology of pouring acrylic sheet. It is an important part of quality control. Hardness can reflect the purity of raw material, PMMA, weather resistance and high temperature resistance. Hardness directly affects whether the plate will shrink, bend deformation, the surface of the process will appear chapped and so on. Hardness is one of the acrylic plate quality evaluation indexes, the average hardness value of 8 Daluoshi, 9 degrees.
2, thickness (acrylic tolerance)
Acrylic sheet thickness exists acrylic tolerance, so the control of acrylic tolerance is an important manifestation of quality management and production technology. Acrylic production has an international standard ISO7823
Tolerance requirement for casting plate: tolerance = + (0.4 + 0.1 x thickness)
Extrusion plate tolerance: tolerance =< 3 mm thickness: mm thickness: 3 + 10 + 5%% >
3, transparency / whiteness
Strict material selection, advanced recipe follow-up and modern production process to ensure excellent transparency and pure white. The flame is crystal clear after polishing.
