Prducer Zinc Powder 500mesh 600mesh Zinc Powder Factory Price Zinc Powder 7440-66-6

prducer ZinC Powder 500mesh 600mesh Molecular formula: Zinc Molecular weight: 65.38 Physical properties: Light grey metal powders Zinc powder of Chemical properties: Insoluble in water, soluble in acid and alkali, slowly soluble in acetic acid, ammonia. Has the strong reducibility, and acid-base release hydrogen. Be affected with damp be affected with damp agglomerate, stable in dry air and moist air generated in the white of the alkali carbonate and coated the surface. Blue green flame burning in the air, produce zinc oxide. Reaction with sulfuric acid, nitric acid of high purity is slow, when contain small amounts of other metals such as steel, tin, lead, the reaction rate.

Zinc powderuse:
1) Chemical production: Used for insurance powder (sodium sulfate), lithopone lithopone, carved white block sodium bisulfate formaldehyde (times), as a large dosage of reductant, dye intermediates, such as production granularity in zinc powder coating is a bit thick, average particle size of 10 to 12 microns.
2) Zinc anti-corrosion coating production: anti-corrosion of steel components is the main purpose of metal zinc, coating way hot plating, electroplating, thermal spraying, zinc coating, powder coating, etc., including hot dip is the main method
3) Mechanical plating and permeability of galvanized products: Mainly used for screws, nails, wire, nail, such as mechanical galvanizing production, my company production for mechanical galvanizing technology on the production and use of refined zinc powder, airflow speed multi-stage combined mechanism size from 300-1500 purpose.
Storage and Shell life: Package:
With steel drums and woven bag lined with plastic bag packaging, a barrel (bag) net weight 50 kg, or according to customer's requirements
