Product Description

CAS No.:5970-47-8

EINECS:222-477-6

Molecular Formula:ZnCO3·2Zn(OH)2·H2O

Molecular Weigh:342.23

Appearance:White fine amorphous powder, odorless, tasteless.

Solubility:Insoluble in water and alcohol, slightly soluble in ammonia. Soluble in dilute acids and sodium hydroxide.

Characteristics and uses:

The basic zinc carbonate is synthesized from zinc sulfate and pure alkali or ammonium carbonate. Its chemical properties determine that it has the functions of accelerating vulcanization, removing hydrogen sulfide and sterilizing in different fields of use.

1. For the production and catalytic desulfurizer of light convergents and latex film products, pigments and rayon.

2. Use zinc carbonate as light astringent, antiseptic, talcum powder, disinfectant and skin protectant in medicine.

3. Due to the transparency of alkaline zinc carbonate type close to the natural rubber, so in transparent rubber products used as reinforcing agent and vulcanization accelerator, make rubber products with good abrasion resistance, tear resistance and flexibility.
