1.thickness acrylic tolerance: acrylic sheet thickness has 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 casting plate tolerance requirements: tolerance = + (0.4 + 0.1 x thickness) extrusion plate tolerance requirements: tolerance = > 3 mm thickness: + 10%> 3 mm thickness: + 5% 3. transparency / Whiteness: strict raw material selection, advanced formula follow up and present production process production, ensure plate Excellent transparency and purity. The flame was polished and glittering and translucent.
2. hardness: hardness is one of the parameters that best reflect the production process and technology of casting acrylic board, and is an important part of quality control. Hardness can reflect PMMA purity, weatherability and high temperature resistance of raw materials. Hardness directly affects whether the sheet will shrink and bend, and whether there will be chapped surfaces when machining. Hardness is one of the hard indexes to evaluate the quality of acrylic board, and the average hardness of the diamond is about 89 degrees.
