Everyone is familiar with friction material brake pads, but how to distinguish the quality of brake pads? This involves the use of magnesium oxide raw materials. Magnesium oxide products can be divided into many categories according to their physical and chemical properties. The performance of high-end and low-end magnesium oxide in friction materials is very different. Below, Hebei Messi Biology Co., Ltd. will take you to understand the application of magnesium oxide friction materials in brake pads.
Magnesium oxide is mainly used in friction material brake pads for wear-resistant materials, high-temperature flame retardants, and improved material stability. Magnesium oxide can increase the decomposition temperature of resin in brake pads, thereby reducing thermal decay, stabilizing the friction coefficient, improving the density of friction materials, and reducing default calculations. It plays a role in high temperature resistance, wear resistance, increasing toughness, stabilizing products, and reducing brake noise. Therefore, brake pads have high requirements for magnesium oxide. The content of magnesium oxide in friction material brake pads is ≥93%, CaO≤1.5%, and fineness is 325 mesh. There is no requirement for calcium, silicon dioxide <0.02, and it is large and easy to use. Products made from lightweight magnesium oxide are more stable, have a higher pass rate, and are of better quality.
