Specification: Industrial (Rubber ) Grade / Feed Grade / Pharmaceutical Grade
Standard: GB/T3185-92
Quality Assurance: ISO9001-2000
Package: 25KG / drum or PP Woven bags with PE Liners or according to customers requirement
Characteristic:
White hexagonal crystal system crystalline or powder; odorless, nontoxic, and fine and smooth. Relative density is 5.606, refractive index 2.008-2.029, melting point 1975℃. Soluble in acid, sodium hydroxide and ammonium chloride; insoluble in water, ethanol and ammonia; and it is amphoteric oxide. It can absorb carbon trioxide and water in the air to produce zinc carbonate in yellow color. While heated, it becomes yellow and resumes white after cooling down. It is ultraviolet radiation resistant, and will not become black meeting with sulfureted hydrogen.
Application:
Used as white dyestuff and used in printing and dyeing, paper, match and medicine industry. And used in rubber industry as vulcanization activator, reinforcement agent and coloring agent of natural rubber, synthetic rubber and latex. Also used in the processing of zinc chrome yellow, zinc acetate, zinc carbonate, zinc chloride and etc. Furthermore, it is also used for making electron laser materials, fluorescent powder, forage additives, catalysts, magnetic materials and etc.
Processing Method:
Indirect Method: Heat zinc ingot to 1000℃ to have it melted and gasified, and then import hot air for oxidization to produce zinc oxide; after cooling, by cyclone separation to collect fine particles into bag, and thereby finished product of zinc oxide is obtained.
Direct Mthod: Compound calcined zinc ore dust, smokeless coal and lime into balls according to the fixed proportion. Through reduction and smelting, zinc oxide in ore dust is reduced to zinc steam and then have the air imported for oxidization. The produced zinc oxide is collected to obtain the finished product of zinc oxide.
