Friction material brake pads we are not unfamiliar, but how to distinguish the quality of brake pads good or bad? This involves the use of magnesium oxide raw materials, magnesium oxide products according to its physical and chemical properties can be divided into many kinds, high and low end magnesium oxide in the friction material performance role is very different, the following Hebei Messi Biology Co., Ltd. will take you to understand the application of magnesium oxide in the friction material brake pads.
Magnesium oxide in the friction material brake pad is mainly used for wear-resistant materials, high temperature anti-flame agent, improve material stability and other characteristics. Magnesium oxide in the friction material brake pad can improve the decomposition temperature of resin, so as to reduce thermal recession, stabilize the friction coefficient, improve the denseness of friction material, reduce the default calculation. The role of high temperature resistance, wear resistance, increase the toughness, make the product stable, reduce the brake noise, so that the friction material brake pads on magnesium oxide requirements are very high. Friction material brake pads with magnesium oxide content ≥ 93%, CaO ≤ 1.5%, fineness 325 mesh. There is no requirement for calcium, silica <0.02, good volume. Lightweight magnesium oxide makes more stable products, higher qualified rate and better quality.
Messi Biology is a famous magnesium oxide manufacturer in China, is a national high-tech enterprise, Hebei Province “SRDI”(Specialized, Refinement, Differential, Innovation) enterprise, The company specializes in the production of magnesium oxide, magnesium carbonate, magnesium hydroxide and other magnesium salt series products, professional magnesium salt research and development production services, thanks to the love of new and old friends around the country, the company with first-class product quality, perfect after-sales service, good corporate image, won the full affirmation of the community and with hundreds of enterprises at home and abroad to establish business relationships. With new management mode, perfect technology, considerate service and excellent quality as the basis of survival, Messi Biology has successfully gone abroad, the annual export business of foreign trade accounts for 30% of the company, widely recognized by customers at home and abroad.
