Important use of special magnesium oxide in the rubber industry
by Hu Yanchao Magnesium oxide manufacturers in ChinaThe 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!
