Alumina Ceramics:
99 alumina ceramic ABS is an amorphous polymer with no obvious melting point. Due to its various grades and grades, appropriate process parameters should be formulated according to different grades in the injection molding process. Generally, it can be molded at a temperature above 160℃ and below 240℃. Because the temperature is too high, there is a tendency to destroy the rubber phase in ABS, and decomposition begins to occur above 250°C. In the molding process, ABS has good thermal stability and a large range of options, and it is not easy to degrade or decompose. In addition, the melt viscosity of ABS is moderate, and its fluidity is better than that of polyvinyl chloride, polycarbonate, etc., and the cooling and solidification speed of the melt is relatively fast, and generally it can be cold-set within 5~15S. The fluidity of ABS is related to injection temperature and injection pressure, and the injection pressure is slightly more sensitive. For this reason, the injection pressure can be used manually during the molding process to reduce the melt viscosity and improve the filling performance. ABS has different water absorption and adhesion properties due to different components. The surface adhesion and water absorption rate is between 0.2~0.5% and sometimes can reach 0.3~0.8%. In order to obtain a more ideal product, it should be made before molding. Drying treatment reduces the water content to below 0.1%. Otherwise, defects such as bubbles and silver threads will appear on the surface of the part.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
