Magnesium oxide Application:
1.light magnesium oxide is used in ceramic, enamel, refractory crucible, firebrick, etc.
2.Also used as polishing agent, adhesive, paint and paper filler, neoprene promoter, activator.
3.It is used in medicine as an antacid, laxative, for excessive gastric acid and duodenal ulcer,
4.Also used in glass dye, phenolic, plastic and other industries.
5.Dead burning magnesium oxide, namely magnesia, has granular and brick shape, widely used as refractory materials for steel furnaces, cement kilns, glass combustion furnaces, etc.
6.alkaline granular refractory, mainly used for metal refining industry, with block refractory furnace, or granular as maintenance materials, with spray, coating method attached to the furnace wall, in order to strengthen the furnace refractory ability.
7.Magnesium oxide produces positive charge in water, most of the suspended matter is negative charge, play a role in absorption, can improve the filtration effect.
9.One of the main uses is the use of flame retardant, traditional flame retardant materials, widely used halogen containing polymer or halogen containing flame retardant combination of flame retardant mixtures.
10.Used in radio high frequency magnetic rod antenna instead of ferrite. Can also be used to manufacture refractory fiber and other refractory materials
