Zinc oxide is a white or yellowish fine powder, easily dispersed in rubber and latex. It is a reinforcing agent, active agent and vulcanizing agent for natural rubber and synthetic rubber. It is also a colorant and filler for white rubber. After adding active zinc oxide to the rubber compound, it can make the rubber have good wear resistance, tear resistance and elasticity. Used for coloring of paints, inks and varnishes, printing anti-staining agents used in printing and dyeing industry, used to neutralize the acidity of kraft rubber in match industry, increasing the adhesive effect, used as raw material for adhesive plaster in pharmaceutical industry, and also used in Manufacture of pigment zinc chrome yellow, zinc acetate, zinc carbonate, zinc chloride, etc., catalyst for methanol synthesis, desulfurizer for ammonia synthesis, production of glass and glaze, fine particle activated zinc oxide (particle size about 0.1um) can be used Light stabilizer for plastics such as polyolefin and polyvinyl chloride, zinc oxide is also used in pressure sensitive, photocatalysis, photoelectrode, coating, color TV development and other fields.

Zinc oxide is used as white pigment. Because activated zinc oxide has good activation properties, it has been more and more widely used in rubber products. For example, in the V-belt, it can not only replace the ordinary zinc oxide in the same amount, but also reduce 1/2-1/3 The dosage makes the various performance indexes of the rubber stable, and the vulcanization performance is not affected, which reduces the production cost. Fine-grained zinc oxide can be used as medicine. Because zinc oxide has a strong ability to absorb ultraviolet rays, people are paying more and more attention to the application of zinc oxide in cosmetics, such as the development of zinc oxide particles with a particle size of 0.01-0.04um, whose ultraviolet absorption rate and transparency are better than the traditional titanium dioxide particles. it is good.

The coating made of transparent zinc oxide can effectively prevent discoloration of the coating. In addition to being used as cosmetics, this zinc oxide can also be used as a raw material for automotive paints, furniture construction materials, inks, and oil paints, and can also be used as an anti-aging agent for rubber and plastics. The recently developed transparent film for food packaging is coated with transparent zinc oxide on polyethylene film, which can not only improve the ultraviolet resistance of plastic film, but also protect the quality of food. With the development of high technology, people are developing and using zinc oxide whisker materials and ceramics, plastic filter membrane materials, gas sensing elements, electromagnetic shielding materials and large specific surface area zinc oxide materials as reinforcing materials for metals and ceramics
