Zinc Carbonate Basic (CAS 12011-79-9) is a high - quality chemical product. It is a white, odorless powder. The chemical formula of basic zinc carbonate is typically 2ZnCO3·3Zn(OH)2. It has a relatively high purity, ensuring its effectiveness in various applications. The particle size of our product can be controlled to meet different requirements, and it has good stability under normal storage conditions. It is insoluble in water but soluble in dilute acids and alkalis.
1. **Rubber Industry**: Zinc Carbonate Basic is used as an activator in the rubber vulcanization process. It can accelerate the reaction between rubber and sulfur, improve the cross - linking density of the rubber, and enhance the physical and mechanical properties of the rubber products, such as tensile strength, hardness, and wear resistance.
2. **Ceramics**: In the ceramics industry, it is used as a flux and opacifier. It can lower the melting point of the ceramic body, improve the firing process, and give the ceramic products a smooth and white appearance.
3. **Paint and Coatings**: It can be used as a pigment extender in paint and coatings. It helps to improve the hiding power, durability, and corrosion resistance of the coatings.
1. **Rubber Processing**: When using in the rubber industry, first, prepare the rubber compound according to the formula. Then, add the appropriate amount of Zinc Carbonate Basic during the mixing process. The recommended dosage is usually 3 - 5 parts per hundred parts of rubber (phr). Mix thoroughly to ensure uniform dispersion in the rubber matrix.
2. **Ceramics Production**: For ceramics, it can be added to the ceramic raw materials in the form of a powder. The powder should be well - mixed with other raw materials before the shaping process. The amount added depends on the specific requirements of the ceramic product, typically ranging from 1 - 3% of the total raw material weight.
3. **Paint and Coatings**: In paint and coatings formulation, it can be added during the grinding or mixing stage. Disperse it evenly in the coating system to achieve the best performance. The dosage can vary depending on the type of coating, usually between 5 - 15% of the total formulation weight.
1. **Case in the Rubber Industry**: A rubber product manufacturer was producing automotive rubber seals. They used our Zinc Carbonate Basic in their production process. Before using our product, the seals had relatively low tensile strength and poor wear resistance, which led to a high failure rate during use. After adding our high - quality Zinc Carbonate Basic at a dosage of 4 phr, the tensile strength of the rubber seals increased by 20%, and the wear resistance improved significantly. The failure rate in actual use decreased from 10% to less than 3%, greatly improving the quality and reliability of their products.
2. **Case in Ceramics**: A ceramics factory was producing white ceramic tableware. They faced problems with the appearance of the products, such as yellowing and uneven color. By adding 2% of our Zinc Carbonate Basic to their raw materials, the products became smoother, whiter, and more uniform in color. The defective rate due to appearance problems decreased from 8% to 2%, resulting in increased customer satisfaction and market competitiveness.
3. **Case in Paint and Coatings**: A paint company was formulating an anti - corrosion coating for metal substrates. They incorporated our Zinc Carbonate Basic at a dosage of 10% of the total formulation weight. The coating showed excellent corrosion resistance in salt - spray tests, with a significantly longer protection time compared to the previous formulation without Zinc Carbonate Basic. This helped the company to offer a more high - performance product to their customers.
