Toxicity |
Zinc is an essential nutrient and is not regarded as toxic. However, the metal fumes, its oxide fumes, and chloride fumes can produce adverse inhalation effects. Ingestion of soluble salts can cause nausea. |
Superfine zinc powder is mainly used as the key raw material of zinc rich coatings and other high-performance coatings such as anti-corrosion and environmental protection, and is widely used in large steel components, ships, containers, aviation, automobile and other industries, ordinary zinc powder is widely used in metallurgy, chemical industry, pharmaceuticals, dyes, batteries, etc. As a pigment, the hiding power is extremely strong. Has a good anti-rust and resistance to atmospheric erosion. Commonly used in the manufacture of anti-rust paint, strong reducing agent, battery, etc.
Particle size: Super extra, Super fine, Coarse grade
Packaging: Conventional packaging of zinc powder are packed in iron drums or PP bags, both lined with plastic film inner bags (NW 50kg per drum or PP bag). Or packaging in flexible freight bags (NW 500/1000Kg per drum or PP bag).
Storage: Zinc powder products should be stored in dry and ventilative warehouse away from acid, alkali and inflammables. Be cautious of water and fire as well as packaging damage and spillage in storage and transportation. Zinc powder should be used up within three months from the date of manufacture.
