There are many types of magnesium oxide: light magnesium oxide, activated magnesium oxide, magnesium hydroxide, and heavy magnesium oxide.
The production of different products requires the addition of different types of magnesium oxide to achieve the desired effect.
Products suitable for adding light magnesium oxide include:
cables, tires, rubber hoses, butyl rubber plugs, friction materials, petroleum catalysts, oriented silicon steel, dyes, electronic ceramics, fluorescent powder, plastic tracks, glass substrates, thermally conductive plastics, reagents, anti-corrosion Bactericides, magnetic materials, fertilizer catalysts, calcium hydrogen phosphate, lithium magnesium silicate, magnesium stearate, feed, polymer resin, rubber grinding wheels, etc. It mainly acts as an acid absorbing agent, a vulcanization accelerator, and an anti-scorch agent.
Products suitable for adding active magnesium oxide include: adhesives, neoprene rubber, conveyor belts, medical rubber stoppers, glass fiber reinforced plastics, ginseng bleaching, fluororubber, etc. It mainly plays the role of vulcanizing agent, anti-scorch agent, acid absorbing agent, and improving product anti-aging.
Magnesium oxide products can be divided into many types according to their application industries and physical and chemical properties. Of course, they are used in different industries, and their effects are also different.
1 Light magnesium oxide: mainly used in many industries such as rubber, dyes, catalysts, steel ball polishing, electronic ceramics, adhesives, etc., with a wide range of applications.
2. activated magnesium oxide: mainly used in medical rubber products, adhesives and other industries.
3.Magnesium Oxide Special for Adhesives: It has many advantages such as high iodine absorption value, good dispersion and low iron content when used in high-grade adhesives. It can effectively prevent the layering and precipitation of the glue when it is boiled with the resin, and can improve the transparency of the glue. Heat to improve the storage stability of the glue.
4 Magnesium oxide for cable rubber: used in rubber sheathed cables, mining cables, marine cables and other industries, which can improve the performance of cables such as anti-corrosion, acid resistance, and high temperature resistance, and improve working stability under harsh conditions.
5 Magnesium oxide for concentrated nitric acid: used for the purification of dilute nitric acid to produce concentrated nitric acid, mainly for water absorption in the production process.
6. Feed grade magnesium oxide: It is used as an additive for animal feed, which can prevent nervous system diseases in animal feed caused by magnesium deficiency.
7. Pharmaceutical grade magnesium oxide: used in pharmaceutical intermediates and gastric medicine additives, which can effectively control the effects of gastric acid and duodenal ulcer.
8. high-purity magnesia: mainly used for high-temperature-resistant operations, for steelmaking furnace linings in the iron and steel industry, exports, and other industries.
9. Magnesium oxide for brake pads: mainly used for wear-resistant materials, high-temperature-resistant flame retardants, and improved material stability.
10.other special magnesia for special industries: such as reagent grade magnesia, etc.

Industrial magnesia: also known as light magnesia, occupies a very important position in many inorganic salt products. Mainly used in the manufacture of ceramics, enamel, refractory materials, etc.; as fillers in the manufacture of polishing agents, adhesives, and paints; as accelerators and catalysts in artificial fibers and rubber (neoprene, fluororubber); in medicine It is used as an antacid and laxative in the world, and it is used to treat hyperacidity, gastric and duodenal ulcers; it can be used as a decolorizing agent for sugar refining in food processing, and a PH value regulator for ice cream powder; In the construction industry, magnesium oxide can be used to produce magnesium-containing special cement and insulation boards, etc.; the largest use in agriculture is as fertilizer and livestock feed, and it is the main element in the process of value and animal metabolism. , can prevent nervous system dysfunction caused by magnesium deficiency, the so-called pasture spasm; in the chemical industry for the manufacture of metal magnesium and magnesium chemicals, such as magnesium sulfate, magnesium oxide and other chemicals; in addition, also used for Water treatment, flue gas washing and used in glass, dye, cable, silicon steel industry, uranium processing, electronics industry, insulation material industry, as well as in petroleum additives, casting, phenolic plastics and other industries.
Fused (fused) magnesia: fused magnesia is one of the main products of magnesium compounds produced in China. According to the purity, crystal, shape and use of the products obtained, it can be roughly divided into the following types of products: single crystal magnesia, Magnesium oxide polycrystalline, high-purity fused magnesia, fused magnesia for electric heating appliances, fused magnesia for refractory material industry, fused magnesia for ceramic material industry, etc.
