Alumina Ceramics:
The structure of alumina ceramics includes graft copolymers with elastomer as the main chain and graft copolymers with hard ABS resin as the main chain; or a mixture of rubber elastomer and hard ABS resin. In this way, different structures show different properties, elastomers show the toughness of rubber, and hard ABS resins show rigidity, and several varieties such as high impact type, medium impact type, general impact type and special impact type are available. Specifically, as the content of rubber component B (generally 5% to 30%) increases, the elasticity and impact resistance of the resin will increase; but the tensile strength, fluidity, and weather resistance will decrease. As the content of the resin component AS (generally 70%-95%) increases, the surface gloss, mechanical strength, weather resistance, heat resistance, corrosion resistance, electrical properties, and processing properties can be improved. The impact strength etc. will be reduced. The ratio of A and B in the resin component is 30%~35%/80%~65% respectively. Plastic ABS resin is the polymer with the largest output and the most widely used. It organically unifies the various properties of PB, PAN, and PS, and has excellent mechanical properties of toughness, hardness and rigidity. ABS is a terpolymer of acrylonitrile, butadiene and styrene. A stands for acrylonitrile, B stands for butadiene, and S stands for styrene. After actual use, it was found that: ABS plastic pipes are not resistant to sulfuric acid corrosion, and smashed and cracked when encountered with sulfuric acid.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
