Hardness is one of the parameters that can best reflect the production technology and technology of pouring acrylic plate, and it is an important part of quality control. Hardness can reflect the purity of the raw material PMMA, the weather resistance of the plate and high temperature resistance. Hardness directly affects whether the plate will shrink bending deformation, processing when the surface will appear chapped and so on. Hardness is one of the hard indexes to judge the quality of acrylic plate, and the average Dharma hardness value is about 8 and 9 degrees.
2, thickness (acrylic tolerances)
Acrylic plate thickness There are acrylic tolerances, so acrylic tolerance control is an important embodiment of quality management and production technology. Acrylic production has an international standard ISO7823
Tolerance requirements for pouring plates: tolerance =± (0.4 + 0.1 x thickness)
Tolerance Requirements for extrusion plates: tolerances =< 3="" mm="" 厚度:="" ±="" 10="" %="">3 mm Thickness: ±5 per cent
Strict raw material selection, advanced formula follow-up and modern production process production, to ensure excellent plate transparency and pure white degree. The flame is crystal clear after polishing.
