Experts explain the advantages and disadvantages of acrylic
Acrylic is used more and more in life. I believe that many people will feel very strange when they first hear it. Acrylic is a kind of building materials. So what kind of material is acrylic, what are its characteristics, advantages and disadvantages?
Acrylic, also known as PMMA or Acrylic, is derived from English acrylic (acrylic plastic). The chemical name is polymethyl methacrylate, which is an important plastic polymer material developed earlier. It has good transparency, chemical stability and weather resistance, easy dyeing, easy processing and beautiful appearance. Has a wide range of applications. Plexiglass products are generally classified into cast sheets, extruded sheets, and molding compounds.
Hardness is one of the parameters that best reflects the production process and technology of the acrylic sheet, and is an important part of quality control. The hardness can reflect the purity of the raw material PMMA, the weather resistance of the sheet, and the high temperature resistance. The hardness directly affects whether the sheet will shrink and bend, and whether the surface will be cracked during processing. Hardness is one of the hard and good indicators for judging the quality of acrylic sheets. The average Dalhou hardness value is about 8 or 9 degrees.
Thickness (acrylic tolerance)
Acrylic sheet thickness has acrylic tolerances, so the control of acrylic tolerance is an important manifestation of quality management and production technology. Acrylic production has an international standard ISO7823
Tolerance requirements for cast-in-place plates: tolerance = ± (0.4 + 0.1 x thickness)
Tolerance requirements for extruded plates: tolerance = < 3 mm thickness: ± 10 % > 3 mm thickness: ± 5 %
Strict raw material selection, advanced formulation follow-up and modern production processes ensure excellent transparency and whiteness. After the flame is polished, it is crystal clear.
