Factors that harm the friction coefficient of the friction lining of the brake motor:

    1. Temperature is a key element that harms the coefficient of friction. In the whole process of friction, because of the rapid rise in temperature, when the temperature exceeds 200°C, the friction coefficient gradually decreases. When the temperature reaches the melting temperature range of epoxy vulcanized rubber, the friction coefficient suddenly decreases, which is called "thermal fading".

    2. The relatively serious "thermal decay" of the raw materials of the friction lining will cause the high efficiency of the braking system to decrease. In specific applications, friction will be reduced, thereby reducing the actual effect of the braking system. It is very risky and must be prevented. Adding high-temperature friction modifier fillers to friction materials is a reasonable way to reduce and get rid of "thermal decay".

    3. When the temperature of the friction plate slowly decreases after the "heat decay", the friction coefficient will slowly recover to all the original normal conditions, but sometimes the friction coefficient will be repaired to be higher than all the original normal friction coefficients and repaired too much. This is simply "too many repairs".

    4. When the surface of the friction sheet is wetted by water, the friction coefficient will also decrease. When the surface shrinkage water is removed and the dryness is restored, the friction coefficient will be restored. This is the white "recoverable when going out".

    5. When the surface of the friction plate sticks to the oil, the friction coefficient is significantly reduced, but a certain sliding friction force must be maintained to make it still have a certain high efficiency of the braking system.
