Analysis of thermal insulation performance of acrylic sanitary ware

Issuing time:2015-04-29 16:24

With the continuous improvement of people's living standards and the enhancement of people's modern consciousness, acrylic sanitary wares (bathrooms, bathtubs, basins, etc.) have gradually replaced the original Tangci and agate sanitary wares with strong advantages, which have the characteristics of heat preservation, good surface finish, high strength, corrosion resistance, etc. But the quality control of acrylic sanitary ware is particularly important, otherwise it will bring more harm to people's life and body. At present, more than 90% of domestic manufacturers adopt the process of hand lay up FRP. Key points of quality control: plate selection: the preferred material of acrylic products is acrylic plate. At present, domestic manufacturers can be divided into three-layer composite board and single-layer acrylic board according to the main chemical composition.


The three-layer composite board is a three-layer composite structure of organic off duty methacrylic acid methyl acetate on both sides of the middle ABS, which has the characteristics of transparent and bright surface, but its plexiglass layer is easy to dissolve in the process of molding adsorption, and ABS is easy to be corroded, and its processing formability is good, so the selection of the board is required to be thicker, generally greater than 3.sm, otherwise the damage rate will increase. The single-layer acrylic plate is generally made by mixing and calendering of methacrylic acid vinegar and ABS. Its corrosion resistance and surface hardness are higher than that of the three-layer composite plate, but its processing and forming process is difficult to control. Therefore, it is required to select a slightly thinner plate for the production of workpieces with complex modeling. At the same time, it is required to strengthen the careful control of the heating temperature of the plate by the operator and the training of adsorption proficiency. In addition, there are still many substandard acrylic plates in China whose acrylic percentage, softening point temperature and thickness deviation are all lower than the national standard.
