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:
Appearance: slightly yellow powder, 100% spherical particles with an average particle size of 30 nm. 0.4-0.5 g / ml.
Specific surface area (BET): 40-60 m2 / g.
Sieve residue (44 micron sieve): less than 0.10%.
Burn weight loss: less than 3%
Water: less than 1%
CuO (Cu) less than 0.0005
MnO (Mn) less than 0.003
PbO (Pb) less than 0.0001 (XRF)
Zinc Oxide is a commonly used chemical additives, are widely used in the production of plastics, silicate products, synthetic rubber, lubricants, paints, adhesives, ointment, food, batteries, flame retardants and other products in the. The band gap and exciton binding energy of Zinc Oxide are large, the transparency is high, and it has excellent room temperature luminescence properties. In addition, the micro particles of Zinc Oxide as a nano material began to play a role in the relevant fields.
We are hoping to cooperate with partners in global market to creat win-win business.
