Applications of Magnesium Oxide

Release date:2015-05-13 00:00 source: Click:

Magnesium oxide manufacturer is to determine sulfur and arsenic in coal, pyrite and steel. Standard for white pigments. Lightweight magnesium oxide is mainly used as raw materials for making ceramics, enamels, refractory crucibles and refractory bricks. It is also used as a polishing agent, adhesives url], fillers for paper, accelerators and activators for chloroprene rubber and fluororubber. After mixing with magnesium chloride and other solutions, magnesium oxide can be prepared for water regulation. It is used in medicine as an antacid and laxative, in gastric acid excess and gastrointestinal ulcer, and in chemical industry as a catalyst and raw material for making magnesium salt. It is also used for glazing, dyeing meal, phenolic plastics and so on. Heavy Magnesium Oxide is used for grinding and semi-roller in rice milling industry. The construction industry is used to make artificial chemical floor, artificial marble heat-proof board, sound-proof board, plastic industry as filling material. It can also be used to produce other magnesium salts.

Used in rubber, plastics, wire, cable dyes, paint, glass, ceramics, chemical reagents, medicine, food additives, etc.

Used in libraries to prevent books from being corroded by acid.

Insulation skin for conductors;

For the treatment of heartburn, gastric acid and acid dyspepsia;

Used as a short-acting laxative;

Used as magnesium supplement;

Because it is difficult to melt, it can be used as furnace lining.

Used as a white reference in colorimetry; (Emissivity is about 0.9)

Fine magnesium oxide can be used as optical coatings. When the thickness of the coating is between 300 nanometers and 7 millimeters, the coating is transparent. The refractive index of the coating is 1.72 mm thick.

It can be used for climbing stones. It can smoke sweat. Attention: Inhalation of magnesium oxide smoke can lead to metal moyamoya disease.

Mainly used in the preparation of oral medicines to neutralize excessive gastric acid. Commonly used preparations are: magnesium emulsion - emulsion; magnesium cover tablets - each tablet contains 0.1g of MgO; acid powder - magnesium oxide and sodium bicarbonate mixed powder, etc.

Magnesium oxide content and activity in a range is proportional and beyond this range is inverse ratio!

Now magnesium oxide is misunderstood by most people as light burning powder. In fact, this understanding is wrong. Light burning powder can be said to be a kind of magnesium oxide. Its nickname is light burning magnesium, light burning magnesium oxide, magnesite, bitter soil powder (Japanese translation), magnesium calcium powder (because light burning powder contains calcium oxide) in building materials industry light burning powder, the lower the content of calcium oxide, the better!

Properties: White light powder, tasteless, exposed to air, easy to absorb water and carbon dioxide, this product is soluble in acid and ammonium salt, insoluble in water and ethanol, melting point 2800, boiling point 3600, magnesium oxide has a high fire resistance and insulation performance, melting point is high.

One of the main uses of magnesium oxide is as a flame retardant. Traditional flame retardant materials widely use halogen-containing polymer or halogen-containing flame retardant mixture. However, once a fire occurs, due to thermal decomposition and combustion, a large number of smoke and toxic corrosive gases will be generated, which hinders fire fighting and evacuation of personnel, corrodes instruments and equipment. In particular, it was found that more than 80% of the deaths in fires were caused by smoke and toxic gases produced by materials. Therefore, besides flame retardant efficiency, low smoke and low toxicity are also indispensable indicators of flame retardants. The development of China's flame retardant industry is extremely unbalanced. Chlorine-based flame retardants account for a large proportion, ranking first among all flame retardants, among which chlorinated paraffin is the monopoly. But when chlorine flame retardants act, they release toxic gases, which is far from the harmless and efficient pursuit of modern life. Therefore, in order to conform to the world flame retardant development trend of low smoke, low toxicity and no pollution, the development, production and application of magnesium oxide flame retardant is imperative.

Magnesium oxide as a flame retardant has a very broad development prospects from the current situation. With the substitution of traditional flame retardants, more and more attention has been paid to the market prospects of magnesium oxide.

Magnesium oxide can also be used as a neutralizer. Magnesium oxide is alkaline and has good adsorption performance. It can be used as a neutralizer for acid-containing waste gas, wastewater treatment, heavy metals and organic wastewater treatment. With the improvement of environmental protection requirements, domestic demand is growing rapidly.
