Main uses: Yangshan County Zhongqi Industrial Co., Ltd. is a company specializing in the production of high-quality calcium carbonate.
1. Rubber industry (rubber - heavy calcium carbonate powder for rubber 400 mesh, whiteness: 93%, calcium carbonate: 96%) Calcium carbonate powder is one of the largest fillers used in the rubber industry one. Calcium carbonate powder is filled in large amounts in rubber, which can increase the volume of its products and save expensive natural rubber, thus greatly reducing costs. Calcium carbonate powder is filled into rubber to obtain higher tensile strength, tear strength and wear resistance than pure rubber vulcanization.
2. Plastic industry (Plastics - Plastic masterbatch uses heavy calcium powder 400 mesh, which requires good whiteness after burning. Calcium carbonate powder content: 99%, whiteness: 95%) Calcium carbonate powder is used in plastics It can play a skeleton role in the product, which plays a great role in the dimensional stability of the plastic product. It can also increase the hardness of the product and improve the surface gloss and surface smoothness of the product. Since the whiteness of calcium carbonate powder is above 90, it can also replace expensive white pigments.
3. Paint industry (paint-latex paint uses heavy calcium carbonate (heavy calcium powder) 800 mesh or 1000 mesh, whiteness: 95%, calcium carbonate: 9%) calcium carbonate powder in the paint industry The dosage is also larger, for example, the dosage in thick paint is more than 30%.
4. Water-based coating industry (heavy calcium carbonate (heavy calcium powder) for water-based coatings, 800 mesh or 1000 mesh, whiteness: 95%, calcium carbonate: 96%,) Calcium carbonate powder is used in water-based coatings It has a wider range of uses in the industry. It can make the coating non-settling, easy to disperse, and have good gloss. The dosage in water-based coatings is 20-60%.
5. Papermaking industry (heavy calcium carbonate (heavy calcium powder) for papermaking: 325 mesh, whiteness requirement: 95%, calcium carbonate content: 98%) The important role of calcium carbonate powder in the papermaking industry . It can ensure the strength and whiteness of the paper and the cost is low.
