Dark gray powder metal zinc, can make pigment, strong hiding power. Has the very good rust prevention and the role of resistance to atmospheric corrosion. Commonly used to manufacture the antirust paint, strong reducing agent, etc.
Zinc is an essential part of rubber and tire industry additive, also used as a natural rubber, synthetic rubber and latex vulcanizing agent and reinforcing agent and colouring agent. If make ordinary zinc oxide nanometer zinc oxide used in rubber, can fully give play to the role of vulcanization, improve the performance of rubber, its amount is only 30% ~ 50% of ordinary zinc oxide.
In the chemical industry, zinc oxide is widely used as a catalyst, desulfurization agent, such as methanol synthesis catalyst, synthetic ammonia as desulfurization agent; Nanometer zinc oxide on the surface of highly active can improve the efficiency of the choice of catalysts and catalytic performance, has wide application potential market.
In the coating industry, zinc oxide besides has the tinting strength and hiding power, and coating of preservatives and FaGuangJi; In addition, the nanometer zinc oxide is excellent ability of uv shielding in the anti-aging coating has more prominent features.
In the pharmaceutical and health care and food industry, zinc oxide with poison, hemostatic, raw muscle pull convergence of function, also used for adhesive plaster material, but to promote children's mental development have help; Nanometer zinc oxide is used to the food hygiene industry demands in gradually expanding, but the product is strict, especially the harmful heavy metal element content.
In the glass industry, zinc oxide in special glass products; In the ceramic industry, zinc oxide is used as flux; In the printing and dyeing industry, zinc oxide is used as reserving agent; Nanometer zinc oxide due to their high activity and can reduce the sintering temperature of glass and ceramics, in addition to the preparation of nanometer zinc oxide using ceramic glaze is more bright and clean, and has antibacterial, prevent enzyme, deodorization etc.
In the electronic industry, zno is not only the main raw material, varistor is magnetic, optical materials such as the main additives. Varistor nano zinc oxide preparation, not only has low sintering temperature, and pressure sensitive resistance performance was improved, such as flow capacity, nonlinear coefficient and so on. The application of nano zinc oxide in optics research along with the development of nanometer zinc oxide optical performance will get bigger breakthrough.
