Active Zinc Oxide

Active zinc oxide is white or light yellow spherical fine powder, density 5.47g/cm3, melting point 1800 C, insoluble
In water, soluble in acid, alkali chloride and ammonia. Carbon dioxide production in the humid air, basic zinc carbonate. Its maximum

Characterized by particle size 50-100 nm, than the indirect method zinc oxide and zinc oxide direct method has a greater surface area, in the application

Has higher activity and good dispersion.

Application:

1, with a rolling good, excellent dispersion characteristics, coupled with its small size, light and loose structure, nitrogen adsorption surface area, making it as a cure activator, the distribution in the rubber compound, and curing hydrogen contact area, greater opportunities for interface reaction, coupled with the active substances in this product to help urge the role of the zinc oxide into zinc sulfide conversion rate. Therefore, as synthetic rubber vulcanization accelerator and a good reinforcing agent, the amount of ordinary zinc oxide 50-70%.

2, in the rubber industry as UV stabilizers, air resistance of polyethylene can get a better improvement.

3, react with the resin acid zinc obtained resin used to produce fast-drying ink, has a good color effect.

4, made of zinc oxide desulfurization agent with a large surface area, and the penetration of high sulfur capacity, high mechanical strength, accumulation of a large gap, small pressure drop characteristics. Widely used in full as ammonia, methanol and hydrogen and other industrial raw materials, gas, oil deep sulfur removal process. At a certain temperature and pressure the small amount of hydrogen sulfide gas can, effectively reduce the concentration of organic sulfur.
