Product Use
Chemical production:
For insurance powder (Ci sodium), lithopone (lithopone), carved white block (sodium bisulfate formaldehyde), dye intermediates such as the production of a larger amount of reducing agent, particle size slightly compared with zinc coating rough average particle size of 10-12μm.
Zinc corrosion coating production:
Steel components zinc metal corrosion is the main purpose, there are hot dip coating method, plating, thermal spraying, zinc-rich paint, powder coating, etc., which is the most important method of Redu.Mainly used for hot-dip zinc-rich coating and electroplating unsuitable large components, such as a large outdoor steel (marine engineering, bridges, pipelines, highway guardrail, etc.), ships, containers and other coating. According to different film base material, zinc-rich coating can be divided into organic and inorganic zinc-rich coating zinc-rich coating. Organic zinc-rich coatings used epoxy ester, epoxy resin, chlorinated rubber, ethylene-based resin and polyurethane resin as the film base material, the content of zinc in the dry film in the 85% -92%. Inorganic zinc-rich paint with water-based lithium silicate, potassium silicate, water, mud or water TEOS as the base material, zinc content in the dry film 92%. Zinc coating, the average particle size of 2-3μm and 5-7μm two specifications, the powder was a narrow grain size distribution, good dispersion.
Mechanical plating and galvanizing production infiltration:
Mainly used for screws, nails, wire, nail and other mechanical galvanizing, my company for the production and use of mechanical galvanizing process to produce refined zinc, airflow speed multi-level granularity from 300-1500 purpose combination agencies, major Specifications 5 #, 6 #, 8 #, 10 #, suitable for different levels of technical standards required mechanical galvanizing process, coating smooth. In addition, I produced for diffusion coating technology requires a special zinc, with a particle size distribution, in the course of easy oxidation characteristics.
Hydrometallurgy:
Replacement for solution purification and metal recycling, such as refining gold, silver, non-ferrous metals
Pharmaceuticals and pesticides:
Zinc as a reducing agent for the production of salicylic acid, indomethacin, aminopyrine, etc., as a raw material for the production of Zineb, zinc phosphide, efficiency and low toxicity pesticides daisy enzymes.
Other
Packing: steel drums and woven bag lined with plastic barrel (bags) net weight 50KG, or according to customer requirements.
Transport and storage:
1, zinc during transport should be moisture, fire, impact and avoid falling.
2, zinc powder should be stored in ventilated, dry and fireproof warehouse.
