Ascension is the throat of the mine production system,Brake as the last line of hoist is the key security system,the main form of it is the disc brake. Braking is accomplished by friction pair of friction, It is a process of kinetic energy of heat, Used for the friction for friction materials, brake is a safe and reliable guarantee. Mine hoist brake shoe is the main part, if the brake shoe friction coefficient of performance can not meet the design requirements, such as there will be produce equipment and the possibility of personal injury. In the process of mine production, the disc brake shoe frequently with the brake disc friction to control the normal operation of the hoist, brake shoe once failure, will lead to hoist a major accident.
So, choose the high friction coefficient, using cycle longer disc brake shoe is particularly important.
ZTIC specializing in the production of environmental protection clean mine hoist brake shoe, drilling rig brake shoe, large equipment friction block, the national standard, gb contracting mould design and production of related products.

China's use of disc brake shoe materials are mostly adopted by the asbestos In the past for a long time, Asbestos main characteristics are: large friction coefficient, good mechanical strength, high melting point, and the bonding agent has a strong adsorption capacity, But there may be some difficult to overcome shortcomings in asbestos brake shoe:
Asbestos completely dehydrated at 650 ℃, 700 ℃ after decomposition, its strength will reduce;
Due to poor thermal conductivity of asbestos, can cause friction heat is difficult to disappear quickly, resulting in heat recession layer thickening, wear, and also will pollute the environment, especially asbestos fiber dust, it can make human body produce canceration;
Asbestos friction performance is seen "hot" recession.
To improve the coefficient of friction and heat dissipation performance, most manufacturers use high hardness abrasive and steel wool.
ZTIC production of environmentally friendly non-asbestos brake shoe, is a kind of the resin and reinforcing fiber are other instead of asbestos friction material, its features are:
Do not contain asbestos, green environmental protection;
High friction coefficient and good mechanical strength, small heat recession;
Low abrasion, use cycle is long;
Excluding steel wool and high abrasive hardness, low hardness, not easy to damage the brake disc.
As people's growing environmental consciousness and the ego to protect consciousness, environmental protection will eventually replace the asbestos non-asbestos brake shoe brake shoe, the mainstream products.
