Automobile brake pad manufacturers take you to understand the wear resistance of friction pads
Brake pad manufacturers take you to understand the wear resistance of friction pads: the wear resistance of friction materials is not only the performance of its service life, but also an important technical indicator to measure the durability of conflict data. The better the wear resistance, the longer its service life. However, the wear of friction materials during the working process is mainly caused by the shear force occurring on the friction contact surface.
Operating temperature is an important factor of hard wear. When the surface temperature of the data reaches the thermal differentiation temperature scale of the organic adhesive, the rubber and resin will differentiate, carbonize and lose weight. With the increase of temperature, this phenomenon intensifies, the bonding effect decreases, and the amount of wear increases sharply, which is called thermal wear.
The selection of suitable anti-friction fillers, resins and rubbers with outstanding heat resistance can effectively reduce the working wear of materials, especially thermal wear, and extend their service life.
In the process of friction material testing, the tested sample will have different degrees of thermal expansion under the influence of high temperature, covering the thickness of the sample wear, and sometimes even negative, that is, the thickness of the sample is added after high temperature wear, which cannot really reflect the actual wear. Therefore, our factory can not only measure the volume wear of the sample, but also measure the mass wear rate of the sample.Brake pad production company, brake pad manufacturers
