In the industrial manufacture, the half of ZnO flow to rubber industry. Among these industry, the tire industry is the largest market of ZnO. However, when the zinc was released into the environment, and entered rivulet,river, and ocean, some zinc metal will infect microorganism and aquatic organism. The rubber material is the main source of zinc pollution in the environment. Today, Meishen Technology talks something about magnesium oxide and zinc oxide with you.
During the tire vulcanization, zinc or zinc oxide is used as catalyst. It not only can accelerate curing speed, but also improve rubber’s conductivity. It is help to the tire heat dissipation.
At present, the tire industry mainly uses ZnO, and a few enterprise adopt other more suitable material, for example, magnesium oxide. It is a necessary trend for the future to decrease ZnO usage amount.
Now, magnesium oxide can be used in all-steel radial tire, semisteel radial tire. Some butyl rubber inner tube also uses magnesium oxide.
