Friction materials are widely used in all kinds of transportation means such as cars, trains, planes, ships, and clutch, brake, brake material. Automotive friction materials mainly are the clutch and brake lining, which is not only the security parts, but also the vulnerable parts. It has little dosage but occupy an important role in car compartment. Modern society has the higher and higher requirements of environmental protection and safety, The developed countries of world automobile industry have rapidly launched non-asbestos friction materials research and development, successively introduced non-asbestos type semimetal friction material, sintered metal type of friction material, alternative fiber reinforced polymers or adhesive friction material, composite fiber friction material, ceramic fiber friction material and so on.
These new type of friction material has the following common characteristics:
1.Increased the metal components, to improve the use of the friction material humidity and life;
2.Don’t contain asbestos ingredient, using alternative fiber or polymer as reinforced material;
3.Add a variety of additives or fillers, to reduce the brake noise and vibration phenomenon, optimizing the friction stability and resistance to viscosity;
Nowadays, friction materials are closely linked to daily life, for example, brake pads. The quality of the products completely determines the safety guarantee, and the quality of magnesium oxide also affects the quality of the product completely.
The functions of magnesium oxide for friction materials: high temperature resistance, abrasion resistance, increasing toughness, friction coefficient, reduce the brake noise, make the product performance is stable. The requirements of magnesium oxide for friction materials: MgO≥93%, CaO≤1.5%, fineness of 325 mesh, relatively speaking, large volume works well.
Meishen Technology Co.,LTD is professional in manufacturing of magnesium oxide, magnesium carbonate and magnesium sulphate, best quality and stable performance make us more famous. Because of different industry demand for specifications, we can supply professional customized according to customer’s requirements.
