Fluorite as friction material for brake pads
The chemical formula of fluorite is CaF2, also known as fluorspar, which is a halogen mineral, white solid powder, melting point 1360°C, and belongs to the equiaxed crystal system. Fluorite comes from volcanic magma. During the cooling process of the magma, the gas-water solution separated by the magma contains many substances, mainly fluorine. When the solution rises along the cracks, the temperature and pressure decrease, and the fluorine in the gas-water solution The ions combine with calcium ions in the surrounding rock to form calcium fluoride, which crystallizes on cooling to give fluorite. When fluorite is used as a friction material, it has good high and low temperature friction performance and good adsorption performance, and its price is low, so it can be used in a higher proportion in the formulation components.
Recycled tire powder material for brake pad friction material
Waste tire reclaimed rubber powder is to separate the steel wire and fiber inside the tire through various technologies and grind the rubber block into rubber powder. In friction materials, products with rubber powder particles between 60 and 100 mesh are generally used. Since the finer the rubber powder, the higher the requirements for the production process, the cost will be high, but the finer the product is used in friction materials. The better the improvement effect on the wear rate of the friction material and the absorption of noise.
