Alumina Ceramics:
Alumina ceramics is a terpolymer of acrylonitrile (A), butadiene (B), and styrene (S). The relative content of the three monomers can be changed arbitrarily to make various resins.
Alumina ceramics have the common properties of the three components. A makes it resistant to chemical corrosion, heat resistance, and has a certain surface hardness, B makes it have high elasticity and toughness, and S makes it have the processing and molding characteristics of thermoplastics and improve Electrical performance. Therefore, ABS plastic is a kind of "tough, hard and rigid" material with easy-to-obtain raw materials, good comprehensive performance, low price and wide range of uses. ABS plastic has been widely used in machinery, electrical, textile, automobile, airplane, ship and other manufacturing industries and chemical industries. Start-up and shutdown have strict requirements for flame-retardant ABS in order to prevent the decomposition of flame retardants. When starting up, the barrel should be cleaned with general-purpose ABS before processing. Before the shutdown (referring to the shutdown for more than 20 minutes), on the one hand, the temperature of the barrel must be reduced to below 100°C, on the other hand, the material in the barrel must be emptied, and the barrel can be shut down after cleaning the barrel with general-purpose ABS. Its purpose is to prevent the decomposition of flame-retardant ABS. Utilization of recycled materials For primary or secondary clean ABS recycled materials with no impurities and no decomposition products, they can be used directly after crushing, or mixed with new materials, and the mixing ratio is generally not more than 25 of the new materials. %, so as not to affect performance. For recycled materials that have been regenerated more than 5 times or added with colorants, they are generally not mixed with new materials to prevent color difference. Regardless of whether it is a single recycled material or a recycled material mixed with a new material, it must be dried according to the regulations before it can be put into molding processing.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
