Messi Biology said, magnesium oxide and magnesium carbonate is an important additive in rubber products, many foreign brand-name tires whose magnesium oxide \ magnesium carbonate dosage is much higher than the domestic ordinary level, generally about 3-7 copies. Magnesium oxide \ magnesium carbonate in an increase of 30%-70% after the rubber tire heat, aging and other aspects of performance did not change significantly, but its wear reduction is significantly better than ordinary tires, and magnesium oxide \ magnesium carbonate after the increase in the density of the tire has a significant reduction, not only effectively reduce the cost and quality of rubber, and greatly improve the performance of rubber.
Magnesium oxide is generally divided into light magnesium oxide and heavy magnesium oxide according to its bulk density, and can be divided into high activity magnesium oxide, medium activity magnesium oxide, low activity and relatively inert magnesium oxide according to its chemical activity degree. Generally speaking, the light active magnesium oxide can be used as CPE vulcanization auxiliary, when choosing magnesium oxide, do not only pay attention to its content mistakenly think that the higher the content is the better. Instead, we should consider the quality of...
