Manufacturers direct Zinc Oxide indirect method Zinc Oxide
Zinc Oxide is a white or light yellow powder, non-toxic, no odor. Its density is 5.6/ cubic meters, the molecular weight is 81.4, the sublimation temperature is 1800 degrees celsius. Insoluble in water, soluble in strong acid and strong alkali.
There are three ways to make a Zinc Oxide, that is, the indirect method (France), the direct method (the United States method) and the wet chemical method. Indirect method for metal zinc ingots as raw materials, the molten zinc into the evaporation in the crucible of, the burning heat of the air oxidation, cooling and trapping set to obtain the finished product. The direct method takes the zinc oxide ore as the raw material, and the coal powder as the reducing agent, and the zinc vapor generated by the direct combustion at high temperature and the hot air contact oxidation to generate the product of Zinc Oxide, cooling and trapping. Wet chemical method with zinc material as raw material, the raw material dissolved in sulfuric acid, with delivery to obtain refined zinc sulfate solution, adding a precipitating agent for zinc carbonate, the roasting solution by zinc oxide.
Rubber and tire industry is the largest user of Zinc Oxide, in the rubber vulcanization process, can increase the physical properties of rubber. Zinc Oxide is also used in paint, ink, varnished cloth color. It can also be used as lubricating oil additives, water treatment and catalyst and other chemical industries. Zinc Oxide is the use of wet chemical production of ultra fine active Zinc Oxide. It has a large surface area, can be very good dispersion in the rubber, harmful impurities content is low, the amount of the princess in the rubber indirect method of Zinc Oxide 50-70%, its performance indicators are as follows:
