Application
Feed industry: as a nutritional additive of zinc, it can inhibit the production of harmful bacteria and maintain the balance of intestinal flora. The specific surface area of active zinc oxide is large, which is conducive to the absorption of nutrients. At the same time, it can prevent and control the incidence of diarrhea in weaned piglets.
Rubber industry: used as activator, vulcanization accelerator and reinforcing agent, which can make rubber products have good wear resistance, tear resistance and elasticity.
Ceramic industry: it has a strong melting aid effect, which can reduce the expansion coefficient of glaze, improve the thermal stability of products, increase the luster and whiteness of ceramic glaze and improve the elasticity of glaze.
Zinc oxide is a kind of pure white powder, which is composed of amorphous or needle like small particles. As a basic chemical raw material, it has a wide range of applications, such as rubber electronics, medicine, coatings and other industries. Zinc oxide can be used as white pigment in printing and dyeing, papermaking, match and pharmaceutical industry. In rubber industry, it is used as vulcanizing agent, reinforcing agent and colorant of natural rubber, synthetic rubber and latex. It is also used in the manufacture of pigment zinc chrome yellow, zinc acetate, zinc carbonate, zinc chloride, etc. In addition, it is also used in electron laser materials, phosphors, feed additives, catalysts, etc. In medicine, it is used to make ointment, zinc paste, rubber paste, etc.
