Magnesium oxide is widely used in the rubber industry, and the addition of magnesium oxide to rubber products can have many unexpected effects.
Magnesium oxide is mainly used with the following rubber products: chloroprene rubber, CPE, brominated butyl rubber, halogenated butyl rubber, fluororubber, nitrile rubber, chlorosulfonated vinyl rubber and other rubber products. Different products need to be added with different content and ratio of magnesium oxide, and the effect of magnesium oxide in products is also different.
The addition of magnesium oxide at the beginning of mixing prevents early crosslinking and cyclization of neoprene and increases the safety of the operation.When vulcanization becomes vulcanization agent, plays the role of hydrogen chloride acceptor, prevents the erosion of hydrogen chloride to fiber tissue.
Magnesium oxide can improve heat resistance and aging resistance. The quality of magnesium oxide has great influence on chloroprene gum processing and vulcanization.When the dosage of magnesium oxide is increased to 10 parts, the colloids have higher plasticity and better storage stability.
Zinc oxide is mainly used as vulcanizing gum to make vulcanization smooth.Although the heat resistance and aging resistance can be improved by increasing the amount of zinc oxide, the adhesive is easy to be burnt and the storage stability of the adhesive is reduced.A large amount of use can also make the adhesive harden and lose plasticity.
But it can increase the curing speed, improve the curing degree and high temperature resistance. General magnesium oxide and zinc oxide used at the same time so as to solve the vulcanized gum easy burning shape and high degree of vulcanization and vulcanization speed, cutting crosslinking degree is much higher than single use.
Hebei Meishen Technology Co., Ltd. is specialized in producing special rubber magnesium oxide, cooperating with many large rubber manufacturers across the country. With rich experience, we can accurately recommend suitable products for customers.
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.
