Active Zinc Oxide Powder
Active zinc oxide is a white or slightly yellow spherical fine powder, bulk density 0.35-0.45, melting point 1800 °C, insoluble in water, soluble in acid, alkali, chloride and ammonia. The humid air with carbon dioxide to generate basic zinc carbonate, its biggest feature is the size of 150-300 nm. Than the indirect method and the direct method zinc oxide zinc oxide have greater surface area, in applications with higher activity and good dispersibility. The refractive index of the active zinc oxide are very similar to natural rubber, vulcanized products thus make the color more clear and transparent.
The advanced production technology and excellent test methods are introduced from shanghai. Quality management system is through the ISO9001 certification. The purity of product is high and the index is superior to the domestic and international advanced standards. We can also meet the special requirements of users.3.Index:

4.1 a rolling resistance, good dispersion characteristics. Coupled with its small size, light and porous structure, a nitrogen adsorption specific surface area. It is used as the curing active agent, uniformly distributed in the rubber compound, and hydrogen sulfide in the contact area, greater opportunities for the interfacial reaction. This product is coupled with a co-catalyst effect of the active substance, into the zinc oxide to zinc sulfide conversion rate. Therefore, the synthetic rubber vulcanization accelerator and good reinforcing agent, the amount of zinc oxide in general 50-70%.
4.2 in the plastics industry as UV stabilizers, anti-atmospheric resistance of polyethylene can be better improved.
4.3 and resin acids obtained by reacting zinc resins used to produce quick-drying inks, with good coloring effect.
4.4 made of zinc oxide desulfurizer, with a large surface area, high sulfur capacity, high mechanical strength, stacking large gap, small bed pressure drop characteristics. Widely used in full into ammonia, methanol and hydrogen gas and other industrial raw materials, deep desulfurization of oil purification process. At a temperature and pressure of trace hydrogen sulfide gas can, effectively reduce the concentration of organic sulfur.
4.5 active zinc oxide has a strong ability to absorb infrared light, the absorption rate and the ratio of the large heat capacity, can be used in infrared detectors and infrared sensors. Active zinc oxide also has a quality of light, light in color, absorbing ability and other characteristics. Can effectively absorb radar waves, and attenuation, absorbing new stealth materials used.
