Since June 2010, Zhejiang Feihang Industry and Trade Co., Ltd. has introduced the proprietary technology of non-asbestos carbon fiber disc friction disc preparation technology, it has been committed to the in-depth development and promotion of non-asbestos carbon fiber disc friction discs. The proprietary technology introduced covers the manufacturing process of non-asbestos carbon fiber disc friction discs for cars, light vehicles, heavy vehicles and passenger cars. The asbestos-free carbon fiber friction plate adopts carbon fiber and other friction materials with the advantages of heat resistance, wear resistance, corrosion resistance and suitable thermal expansion coefficient, and the product is cost-effective. Compared to the original asbestos brake linings, the non-asbestos carbon fiber friction linings are characterized by low braking noise, low wear rate, long service life, excellent high temperature performance, and good impact resistance, and are more efficient, energy-saving and environmentally friendly. Lou Zhibo, chairman of Zhejiang Feihang Industry and Trade Co., Ltd., said that the non-asbestos carbon fiber friction plate has sufficient mechanical properties, superior friction and wear properties, good resistance to thermal degradation and recovery performance, and the product is more common than ordinary brake linings for automobiles. The service life of the film increases by more than 20,000 kilometers, which has a good market prospect for promotion. The company will take the introduction of project patents as a new starting point, further refine, expand, and strengthen the non-asbestos carbon fiber friction sheet industry, and will contribute to the development of high-tech automotive key parts and components in our city.
It can be prepared by directly crushing natural calcite, limestone, chalk, shell, etc. by mechanical methods (using Raymond mill or other high-pressure mill). Because the sedimentation volume of heavy Calcium Carbonate is smaller than that of light calcium carbonate, it is called heavy calcium carbonate.
Heavy calcium carbonate is abbreviated as heavy calcium. It uses high-quality limestone as raw material and is processed into white powder by a lime mill. Its main component is CaCO3. Heavy calcium has the characteristics of high whiteness, good purity, soft hue and stable chemical composition. Heavy calcium is usually used as a filler. It is widely used in daily chemical industries such as artificial floor tiles, rubber, plastics, papermaking, coatings, paints, inks, cables, construction supplies, food, medicine, textiles, feed, toothpaste, etc. Increase the volume of products and reduce production costs. Used in rubber, it can increase the volume of the rubber, improve the processability of the rubber, play a semi-reinforcing or reinforcing role, and can adjust the hardness of the rubber.
