Hebei Messi Biology Co., Ltd. stated that auto parts, as the foundation of the automobile industry, are a necessary factor to support the sustainable and healthy development of the automobile industry. Magnesium oxide is widely used in auto parts and plays an important role.
Tires: With the increase of rubber content, in order to ensure the hardness of the bead wire rubber, the amount of carbon black must be increased, which brings great difficulties to the mixing process of the rubber. The power consumption during mixing is greatly increased, the temperature of the rubber rises quickly, and it is easy to burn. Magnesium oxide mainly plays the role of scorch retarder, vulcanization accelerator, acid absorber, high temperature resistance, and fire retardant in tires. Magnesium oxide has the effect of inhibiting the reaction of sulfur and rubber, so that the free sulfur content in the rubber is maintained at a high level, thereby improving the bonding performance of the rubber and the safety performance of mixing and processing. Hebei Messi Biology Co., Ltd. has tested the application of magnesium oxide in the bead wire rubber of load-bearing bias tires and achieved good results.
Engine oil emulsifier: Magnesium oxide can prevent the fusion of emulsified nuclei and stabilize the emulsion. Antioxidant magnesium can accelerate the separation of oil and water, prevent the gradual formation of pigments in the emulsion, and thus prevent or slow down the leakage of aluminum.
Brake pads: Magnesium oxide in brake pads can increase the decomposition temperature of the resin, thereby reducing thermal decay, and then stabilize the friction coefficient, improve the density of the friction material, and reduce the effect of calculation. At the same time, it can improve the wear resistance and high temperature resistance of the friction material, increase its toughness, make the product more stable, and reduce the braking noise.
