Magnesium oxide usage:
1, one of the main uses of magnesium oxide is used as a flame retardant, traditional flame retardant materials, widely used halogen-containing polymers or halogen-containing flame retardants combined into a flame retardant mixture.
2, another use of magnesium oxide can be used as a neutralizing agent, magnesium oxide alkaline, good adsorption performance, can be used as acid waste gas, wastewater treatment, heavy metals and organic waste treatment and other neutralizing agent, with the environmental requirements, the domestic demand is growing rapidly.
3, the pressure of fine magnesium oxide can be used as optical coatings. Coating thickness between 300nm and 7mm, the coating is transparent. 1mm thick coating refractive index of 1.72.
4, used for climbing stone use, can absorb hand sweat, (Note: inhalation of magnesium oxide smoke can lead to metal smog disease.)
5, mainly used for the preparation of internal pharmaceutical agents to neutralize excess stomach acid. Commonly used preparations are: magnesium milk - emulsion; magnesium cover tablets - each piece contains MgO0.1g,; acid making scatter - magnesium oxide and sodium bicarbonate mixed into the bulk, etc.
6, light magnesium oxide is mainly used as a raw material for the preparation of ceramics, enamel, refractory crucible and refractory bricks. Also used as abrasive binder and paper filler, neoprene and fluorine rubber promoter and activator
