1. 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
2. In the chemical industry, zinc oxide is widely used as a catalyst, desulfurization agent
3. In the coating industry, zinc oxide besides has the tinting strength and hiding power, and a coating of preservatives.
4. In the ceramic industry, zinc oxide is used as flux
5. In the printing and dyeing industry, zinc oxide is used as reserving agent
6. In the electronic industry, zno is not only the main raw material, but also the main additives of magnetic, optical materials
7.In the glass industry, zinc oxide used in special glass products.ZnO as flux, can increase transparency, brightness, and resistance to deformation of tension, can reduce the thermal expansion coefficient
