(1) Powder With ZnO produced by MST is used in the rubber industry: in the rubber vulcanization process of lead-zinc mine equipment, powder With ZnO can improve the physical properties of vulcanized rubber, enhance the activity of accelerators, and shorten the vulcanization time, thereby improving rubber wear resistance and resistance. Pull sex. Secondly, powder With ZnO is used as a reinforcing agent and coloring agent in rubber. It can also be used as a vulcanizing agent for neoprene and a compounding agent to increase thermal conductivity.
(2) Powder With ZnO produced by MST is used in the paint and coating industry: its tinting power, hiding power, anti-corrosion, luminescence and other functions are mainly used. It is often used to produce white paint and enamel. Zinc oxide is slightly alkaline and can react with trace free fatty acids to generate zinc soap, making the paint film flexible and firm, and preventing metal oxidation.
(3) Powder With ZnO produced by MST can be used as an anti-dyeing agent in the printing and dyeing industry; it can be used as a catalyst in the chemical industry. In addition, it can be used as a raw material in the production of opalescent glass, zinc white oil and watercolor pigments, cosmetics and various zinc salts.
