Matters needing attention of Magnesium oxide in tire production
Magnesium oxide is suitable for tire industry, mainly used in all-steel radial tires, semi-steel radial tires, some butyl inner tires are also used.
Magnesium oxide in the tire production process will play an anti-coke agent, vulcanization accelerator, acid absorbent (halogenated butyl rubber in the vulcanization process will release hydrogen chloride), filler, high temperature resistance, fire resistance, wear resistance, corrosion resistance.
Magnesium oxide has certain activity, which is beneficial to improve product quality, prolong coke burning time and improve product flexibility and wear resistance.
When using magnesium oxide in the production process, it should be noted that once magnesium oxide moisture is high, hydrochloric acid insoluble material, water soluble material is too high will appear bubbling, trachoma;
Low content of magnesium oxide will affect its toughness and wear resistance.
Too much calcium can break.
Adhesive pad and metal adhesion is not good, generally this situation is because the rubber is not ripe not through, and lead to adhesion is not good, just like surface and do not through or wake up in a short time, roll out to not smooth not fine.
Because the surface is rough, resulting in poor adhesion with other objects, that is, speaking of the main role is his glue and other main raw materials, magnesium oxide only improve its own performance, but cannot exist independently;
In the process of refining butyl rubber, the phenomenon of softening occurs, in which magnesium oxide plays the role of curing accelerator and anti-coke agent, improve the product itself has this property, if the product itself this property is poor, then magnesium oxide can not play such a big role.
Because magnesium oxide only plays an auxiliary role, if there are problems, it is recommended to check whether the formula of curing system and softening system is reasonable and whether there are some quality problems.
Meishen is the world's leading producer of magnesium oxide, Magnesium oxide is an oxide of magnesium, an ionic compound. It is a white solid at room temperature. Magnesium oxide exists in the form of periclase in nature and is a raw material for magnesium smelting. Magnesium oxide is white or light yellow powder, odorless, tasteless, this product is insoluble in water and ethanol, melting point 2852 ° C, boiling point 3600 ° C, magnesium oxide has high refractory insulation properties. It can be converted into crystal by burning at a temperature above 1000 ° C. If it rises above 1500 ° C, it will form a burnt magnesia or sintered magnesia.
Magnesium oxide can be used in the manufacture of metallurgy, smelting, advanced magnesia bricks, refractory materials and moisturizing materials. It is also widely used in rubber, rubber sheet, rubber products, pharmaceutical industry, food industry, plastic sheet accelerator, glass fiber reinforced plastics and Surface coating of silicon steel sheet, paper production, steel ball polishing, leather treatment, insulation materials, grease, dyes, ceramics, desiccant, resin, flame retardant, etc.
Hebei Meishen Chemical Technology Group is the main magnesium oxide producer in the world. It is also the largest magnesium salt producer in China and has won the ISO9002 quality system certification. It also has GMP-Certification.
With rich experience in the research, development, production, management and operation of magnesium oxide products, Meishen Group has always attached great importance to the research and development of new products and strict requirements on product quality. Meishen has a high-level sales team. The business covers more than 20 countries and regions around the world. It is widely welcomed by new and old customers.
