Zinc carbonate is produced by reacting zinc-containing raw materials (such as zinc oxide, zinc ash, and zinc slag) with sulfuric acid to generate zinc sulfate solution, which is then reacted with soda ash to precipitate zinc carbonate. We use high-quality raw materials, multi-stage impurity removal processes, state-of-the-art equipment, and top-tier technology. The process involves dissolution, heating, and pressure filtration. From the synthesis of zinc carbonate, multiple methods are used to control reaction conditions, ensuring that zinc carbonate particles are generated under controlled conditions. After synthesis, the mixture is washed, separated into solid and liquid components using a diaphragm filter press, dried by airflow, classified by particle size, and then passed through a vibrating screen before packaging. Zinc carbonate is used in medicine as a skin protectant; in animal feed as a zinc supplement; and in the synthesis of high-purity zinc stearate. In rubber processing, zinc carbonate increases the thermal conductivity of rubber compounds, improving their thermal conductivity and vulcanization speed, making it particularly suitable for hot air vulcanization processes. It also improves the shape stability of semi-finished products during vulcanization, which is suitable for moldless products (such as many extruded products using continuous vulcanization processes).
