Reasons for friction material replacement
After more than 200 years of development, friction materials have developed to a relatively stable stage through the survival of the fittest. Many materials have also passed the test of the times. Don't eliminate them or replace them. In the current ratio of friction materials, it is basically obvious that asbestos has been eliminated, and metal materials are slowly decreasing. Why?
1. Asbestos-free meets the requirements of environmental protection. In the early days, asbestos was widely used. Many people who had been exposed to asbestos dust for a long time got asbestosis, which affected people's health. Therefore, they were gradually replaced by other environmentally friendly materials. replace.
2. The purpose of reducing the use of metal materials is to reduce the density of the product, which is beneficial to reduce the damage to the brake disc and the degree of braking noise.
3. Reducing the use of chemical fibers and natural fibers can greatly reduce the material cost of the product and reduce the thermal attenuation of the friction material.
4. Reducing the resin content is conducive to reducing the occurrence of thermal decay, reducing product foaming and expansion
5. The shortening of the hot pressing time can greatly improve the production efficiency of the hot pressing machine, which is suitable for automatic production.
