Application of Magnesium Carbonate in Rubber Tires

Hebei Messi Biology Co., Ltd. stated that magnesium carbonate is a new multifunctional inorganic material. In recent years, it has shown many special functions in catalysis, optics, magnetism, mechanics, etc. Magnesium carbonate has important application value in many fields, such as biology, medicine, etc., and has special characteristics and uses that cannot be compared with ordinary magnesium carbonate.

Magnesium carbonate is a necessary additive for the vulcanization system, and its filling amount is relatively high, generally around 5%. Due to its large specificity and large filling amount, magnesium carbonate has a great influence on the density of the rubber compound. For dynamic products such as tires, the greater the weight, the greater the heat generation and rolling resistance, which is not good for the service life and energy consumption of the product. Especially in modern society, people have put forward high demands on product safety and environmental protection. requirements.

Application of Magnesium Carbonate in Rubber Tires

The amount of magnesium carbonate used in recent foreign brand-name tires is far lower than the domestic average level, generally about 2-3 parts. Reduced use has a greater impact on formulation costs, making it a reality to reduce costs through reduced use. After the use of magnesium carbonate with a reduction of 30%-70%, there is little change in terms of tensile properties, heat generation, aging, etc. compared with the use without reduction, which are far better than ordinary magnesium carbonate; Better than unreduced magnesium carbonate, far better than unreduced common magnesium carbonate. In terms of density, the density of magnesium carbonate after weight reduction is significantly reduced, which is of great help to reduce the cost, reduce the overall weight of the product, and improve the performance of the product. Therefore, in the use of magnesium carbonate, it is recommended to use a reduced amount, which is about 30%-70% of ordinary magnesium carbonate. This reduced use is not only a cost requirement, but more importantly, it should be a performance requirement.
