Zinc powder usage
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.
