Product Name:Technical-Grade Zinc Sulfate Monohydrate Line Products
Type: Zinc sulfate series
Chinese Name:工业级一水硫酸锌系列产品
Molecular formula:ZnSO₄ H₂O
Molecular weight:179.45

Physical and chemical property

White or slight-yellow crystal, loose and no agglomeration, easy soluble in water and slightly dissolvable in alcohol and glycerol, insoluble in liquid ammonia and ketone, tending to lose water molecules of hydration in dry air and become white powder appearance. When the temperature is 280℃, it will become no water substance and lose all crystal water. When the temperature is above 500℃, it will decompose.

Relatively density: 1.975

Molecular weight:287.56

Melting point: 100℃

Use

It is mainly used as raw material for zinc salts, Zinc stearate, Zinc carbonate, Zinc Borate, Triscabol and lithopone and so on. It is used as a main subsidiary material for electroplate pure zinc, electroplate Industry, washing of wood, leather preservation, bone glue fine and preservation and dye stuff in printing and dyeing.

Characteristic and function

High purity, strong disperse, rapid dissolution and rapid and thorough chemistry reaction.

Snow-white color, and the color of remainder after chemical reaction will not change.

Little impurity, high stability, resultant has little impact on the product.

Packaging and transportation

Plastic woven bag lined with plastic film bag. Standard net weight: 25kg, 40kg, 50kg. Avoid moisture during the transportation and store.
