Important use of special magnesium oxide in the rubber industryby Hu Yanchao Magnesium oxide manufacturers in China
The activity of magnesium oxide is an important indicator for measuring magnesium oxide for the rubber industry. Active magnesium oxide is one of the main inorganic active agents, and only a small amount can be added to the rubber to greatly improve the degree of sulfurization.
In rubber, magnesium oxide and zinc oxide mainly exert fluidity and oxygen resistance, and optimize the tensile strength and impact resistance of rubber. Therefore, magnesium oxide is an important compounding agent for halogen-containing rubber.
In chloroprene rubber, magnesium oxide and zinc oxide are mixed as a vulcanizing agent, so that magnesium oxide can reduce the activity of zinc oxide, thereby reducing the vulcanization rate and avoiding the problem of early crosslinking. At the same time, magnesium oxide can also act as an acid acceptor to prevent scorch and cyclization, usually added at the beginning of the kneading. Secondly, the active level of magnesium oxide, that is, the iodine adsorption value, has a great influence on the anti-scorch performance of CR, and has a certain influence on the tensile strength, tensile strength and hardness of CR.
In addition, light magnesium oxide is one of the commonly used varieties. Magnesium oxide is often used in alloy glues. For example, the combination of CM or PVC can ensure that the rubber products are not under sulfur, and the mechanism of action of magnesium oxide in the halogen-containing rubber is consistent.
In summary, although magnesium oxide is not an important material in rubber, it also plays a very important role.
Therefore, Hebei Meishen Technology Co., Ltd. puts forward a proposal for customers who need magnesium oxide. In terms of magnesium oxide demand, customers with strict requirements for activity should choose a strong manufacturer when purchasing active magnesium oxide. After all, the production equipment and technology of the powerful manufacturers are relatively complete and advanced. The control of the activity in the process of calcination is also very mature. Only in this way can we find the suitable active magnesium oxide suitable for your product. Meishen company welcomes you to visit the factory and negotiate cooperation!
