Preparation method of magnesium oxide for heat conduction and insulationby Hu Yanchao Magnesium oxide manufacturers in China
The electrofused magnesium oxide with a purity of no less than 96% was crushed into magnesium oxide powder with different particle sizes of 50-60 mesh, 60-80 mesh, 80-140 mesh, 140-200 mesh, 200-325 mesh and -320 mesh ,Mix by weight ratios of 25%, 20%, 15%, 10% and 5%.
Remove iron, drying, mix with talc powder, active leben-al2o3, mullite powder and rare earth catalyst according to 100, 35, 17, 6, and 2 weight parts in turn, and produce an environmentally friendly heat-conducting and insulating material of magnesium oxide for electric heating.
The thermal insulation material is used to make the electric heat pipe, the temperature is more than 250℃, the performance does not change, will not produce any toxic gas, will not cause pollution to the environment.
Mei shen 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 Mei shen 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, Mei shen Group has always attached great importance to the research and development of new products and strict requirements on product quality.
