Alumina Ceramics:

Alumina ceramic chlorosulfonated polyethylene "When polyethylene reacts with chlorine containing sulfur dioxide, part of the hydrogen atoms in the molecule are replaced by chlorine and a small amount of sulfonyl chloride groups to obtain chlorosulfonated polyethylene. The main industrial manufacturing method is the suspension method. Chlorosulfonated polyethylene is resistant to ozone, chemical corrosion, oil, heat, light, abrasion and tensile strength. It is an elastomer with good comprehensive performance and can be used to make food-contact equipment parts. Cross-linked polyethylene 　 uses radiation method (X-ray, electron beam or ultraviolet radiation, etc.) or chemical method (peroxide or silicone cross-linking) to make linear polyethylene into a network or body-shaped cross-linked polyethylene. Among them, the silicone cross-linking method has a simple process, low operating cost, and molding and cross-linking can be carried out step by step, and blow molding and injection molding are suitable. The heat resistance, environmental stress cracking resistance and mechanical properties of cross-linked polyethylene are greatly improved than polyethylene, and it is suitable for large-scale pipes, cables and wires, and rotomolding products.
Blending modification of polyethylene 　After blending linear low-density polyethylene and low-density polyethylene, it can be used to process films and other products. The product performance is better than low-density polyethylene. The blending of polyethylene and ethylene-propylene rubber can produce a wide range of thermoplastic elastomers. Polyethylene can be divided into high pressure method, medium pressure method, and low pressure method according to polymerization pressure.
The high-pressure method is used to produce low-density polyethylene. This method was developed early. The polyethylene produced by this method has so far accounted for about 2/3 of the total polyethylene output, but with the development of production technology and catalysts, its growth rate has increased. Far behind the low-pressure law. The low pressure method includes slurry method, solution method and gas phase method. The slurry method is mainly used to produce high-density polyethylene, while the solution method and gas phase method can not only produce high-density polyethylene, but also produce medium and low-density polyethylene by adding comonomers, which is also called linear low-density polyethylene. Vinyl. Various low-pressure processes have developed rapidly.

High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
