Knowledge Of Heavy Magnesium Oxideby Hu Yanchao Magnesium oxide manufacturers in China
Heavy magnesium oxide molecular formula MgO, relative molecular mass 40.30.White or beige powder, non-toxic, odorless, tasteless, relative density of 3.58, melting point of 2800℃, insoluble in water and organic solvents, soluble in acid or ammonium salt solution.
Easy to absorb moisture, moisture and carbon dioxide in the air to form magnesium salt. industrial heavy magnesium oxide is used in the magnetic material industry for color television deflection coils (ferrite soft magnetic) and other ferrite magnetic materials ;Steel ball polishing industry to do polish; Electrical industry to do phenolic resin (commonly known as bakelite raw materials; Dye industry to do aminophenol production accessories. It is also used in feed, glass, ceramics, industrial catalysts and environmental protection industries.
The modification of heavy magnesium oxide can be used as a safe alkali-extracting agent in leather industry. Hebei Meishen technology co., LTD. Proposed the modification as a solution for alkali extraction: burning magnesium oxide at high temperature to change its crystal shape and increase its volume density; The compound is modified to reduce the acid center on the surface.
Polymer film coating modification, that is, coating magnesium oxide particles with a layer of organic film, through the mechanical action of the destruction of the membrane structure, so that magnesium oxide is slowly released, to achieve the acid reaction speed slowed down, the pH value of the tanning liquid slowly rise. The results showed that the alkaline extraction of the sample prepared by the film coating of the polymer material was uniform, and the pH value of the tanned liquid could not be changed suddenly and remained stable in a certain range.
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.
