Zinc sulfate
CAS No.: 7446-20-0
EIENCS NO.:231-793-3
H.S. code:2833293000
Molecular formula: ZnS04 • 7H20
Features:
Pure zinc sulfate in the air for a long time without yellow, placed in dry air to lose water and become white powder. There are many kinds of hydrates: in the range of 0-39 ℃, the hydrate is zinc sulfate heptahydrate, 39-60 ℃ is zinc sulfate hexahydrate, and 60-100 ℃ is zinc sulfate monohydrate. Pure zinc sulfate in the air for a long time without yellow, placed in dry air to lose water and become white powder.
Use:
1. Used as a micronutrient fertilizer in agriculture
2. Used as a feed additive
3. For manufacturing lithopone and zinc salt
4. Used as an emetic in medicine
Packing: polypropylene woven bag lined with polyethylene film bag, net weight of each bag is 25KG,5OKG, ton bag.
Storage and transportation: stored in a cool, ventilated warehouse. Keep away from fire and heat source. Prevent direct sunlight. The packaging is sealed. Should be stored separately from the oxidant, do not mix storage.
