Properties:
White hexagonal crystal system crystalline or powder,nontoxic,fine and smooth, Soluble in acid, sodium hydroxide and ammonium chloride; in soluble in water,ethanol and ammonia.
Applications:
1. Used as white dyestuff and used in printing & dyeing ,paper,match and medicine industry.
2. Used in rubber industry as vulcanization activator,reinforecement agent and coloring agent of natural rubber,synthetic rubberand latex.
3. Used in the processing of zinc chrome yellow,zinc acetate,zinc carbonate,zinc chloride, etc.
4. Used for making electron laser materials, flurescent powder,forage additives, catalysts, magnetic materials
Processing 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 products of zinc oxide is obtained.
Packing:
25 kgs in net bag, 20 mts in the 20'FCL
