48.8 Mpa Disc Brake Shoe,
no asbestos brake shoe
Braking is mostly achieved by frictional friction. It is a process of kinetic energy to convert thermal energy. It is used as a friction material for friction. First, the brake is safe and reliable. The brake shoe is the main part of the mine hoist brake. If the friction coefficient of the brake shoe does not meet the design requirements, equipment and personal accidents may occur.
Originally, the brake shoe used in China is mostly made of asbestos material, which is characterized by high melting point, large friction coefficient, good mechanical strength and strong adsorption force with adhesive.
However, asbestos brake shoes also have insurmountable shortcomings:
1. Due to the poor thermal conductivity of asbestos, the frictional heat is difficult to disappear quickly, resulting in thickening and wear of the thermal decay layer, and polluting the environment, especially asbestos fiber dust, can cause cancer in the human body;
2. Most of the high hardness abrasives and steel wool are used to improve the friction coefficient and heat dissipation performance.
3. After asbestos is completely dehydrated and decomposed at 650 ° C - 700 ° C, its strength is reduced;
4, asbestos is prone to frictional performance "thermal decay".
WSM-3 environmentally friendly non-asbestos brake shoe is a friction material that uses resin-based and replaces asbestos with other reinforcing fibers. Its characteristics are:
1. High friction coefficient, good mechanical strength and low thermal decay;
2, does not contain steel wool and high hardness friction agent, low hardness, not easy to damage the brake disc;
3, no asbestos, green and environmental protection;
4. Low wear and long service life.
