zinc oxide - 99.7%min

1.Application of zinc oxide
Zinc oxide is essential for rubber and tire industry additives, also used as natural rubber, synthetic rubber and latex vulcanization active agents and reinforcing agents, and coloring agent. In the chemical industry, zinc oxide is widely used as a catalyst, desulfurization agents, such as when the synthesis of methanol as a catalyst。In the paint industry, zinc oxide addition to color strength and hiding power, the preservative is paint and light-emitting agent; In addition, the nano-ZnO excellent UV shielding capacity of its anti-aging, etc. For coating has more prominent characteristics.
In the medical and health and food industries, zinc oxide has a Said, bleeding, misogynic function of convergence, but also raw materials used in plaster, but also for the promotion of children's intellectual development with the help; nano-zinc oxide used in food hygiene demands of the industry is gradually expanded, in particular the content of harmful heavy metal elements.
In the glass industry, zinc oxide used in the specialty glass products in; in the ceramics industry, zinc oxide used as a flux; in printing and dyeing industry, zinc oxide used to prevent agent; In the electronics industry, zinc oxide varistors is the main raw material, but also magnetic, optical and other materials, the main additive.
