2. Chemical characteristics

Basic zinc carbonate is synthesized from zinc sulfate and soda ash. Its chemical properties determine that it has functions such as accelerating sulfurization, removing hydrogen sulfide, and sterilizing in different application fields. The product has a pure white color, excellent fluidity, and stable physical and chemical properties; The process flow of the company's zinc sulfate production workshop is as follows: coarse leaching - primary oxidation - displacement - secondary oxidation - displacement. High quality raw materials, multi-stage impurity removal process, first-class equipment, and top-notch technology are selected to ensure the purity of the zinc sulfate solution. We use high-quality soda ash according to national standards, which is dissolved, heated, and filtered to ensure its cleanliness and absence of impurities. Starting from the synthesis of zinc carbonate, multiple methods were used to control the reaction conditions, ensuring the controllable generation of basic zinc carbonate particles; The synthesized product is rinsed with soft water, separated by a diaphragm filter press for solid-liquid separation, air dried, graded for particle size, and then passed through a vibrating screen for packaging. The equipment used is fully automated and made of 304 stainless steel. Ensure the high performance and stability of the product from the perspective of process and equipment; The heat source for the company's production is natural gas, and the air used for drying the hot blast stove is filtered to avoid black spots on the product. This ensures that the product has good fluidity while also having a high specific surface area; Rinse with soft water, the product has extremely low soluble salts and meets GMP standards; All products pass through a vibrating screen to ensure fineness. The pure zinc sulfate manufacturing process ensures that the total amount of lead, arsenic, and cadmium heavy metals in our products is within 10PPM; Excellent equipment, advanced technology, and ISO management have created the superior quality of Gemstone brand zinc carbonate.

3. Application:

High purity alkaline zinc carbonate is used as a skin protectant in medicine; Used as a zinc supplement in feed and also for synthesizing high-purity zinc stearate.

Used in industry as a lightweight astringent and latex product, formulated as calamine detergent, and also as a desulfurizer and pore forming agent in the catalyst industry. In rubber products, due to the refractive index of zinc carbonate being close to that of rubber, it is specifically used as a transparent rubber product and as an EVA foam promoter.

4. Packaging: 25kg, double-layer packaging, outer layer covered with film woven bag, inner layer made of waterproof and moisture-proof plastic bag.
