Main uses

1. Basic zinc carbonate is synthesized from zinc sulfate and soda ash or ammonium bicarbonate. It is determined by its chemical properties. In different fields of use, it has the functions of accelerating vulcanization, removing hydrogen sulfide and sterilizing.

2. Used in the production of light astringent and latex film products, pigments, rayon and catalytic desulfurization agent.

3. Basic zinc carbonate is used in medicine as a light astringent, preservative, talcum powder, disinfectant and skin protectant.

4. Since the transparency of basic zinc carbonate is close to that of natural rubber, it is used as a reinforcing agent and vulcanization accelerator in transparent rubber products to make the rubber products have good wear resistance, tear resistance and elasticity.

5. Special basic zinc carbonate for oil fields can react with H2S to form stable insoluble ZnS during oil drilling. This product does not affect the mud performance after being added to the mud, so it can effectively eliminate H2S pollution and corrosion. It can be used as a product containing H2S. Corrosion inhibitor and sulfur removal agent for oil and gas wells.
