CHEMICAL INDUSTRY GRADE ZINC OXIDE

NANO-ZINC OXIDE FOR CHEMICAL INDUSTRY

Zinc oxide as a result of the chemical industry size, large specific surface area, the surface of the bonding state with the particles within the different response to increased access, increased the catalytic efficiency of chemical manufacturers and chemical preparation of the catalyst sorbent material of choice; Zinc oxide  is a good photocatalyst in the ultraviolet radiation, the self-decomposition of the free movement of the negative electron, leaving the positively charged hole, the activation of oxygen in the air to active oxygen, and a variety of organic chemical reaction occurred, killing bacteria and viruses.
