CAS：********8
EINECS：********6
Molecular Formula：ZnCO3·2Zn(OH)2·H2O
Molecular
Weigh：**2.*3
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.
