How is light burnt powder produced

The calcination of magnesite at a high temperature of 750 to 1100 is called "light burning", the resulting product is called light burned magnesium powder, referred to as light burned powder. The main use of light burned powder is as a thermal insulation sound insulation building material Manufacture of cementitious materials, it can also be used as raw materials for the manufacture of ceramics. Lightly burned magnesium powder Because the body of the lightly burned powder biogas tank will be exposed to water for a long time, the product's water resistance requirements are special, it must also have good stability. Use high content of lightly burned magnesium oxide powder, such as: Lightly burnt magnesium oxide powder with 88% content. Selecting ores with special low alkali content in the selection of ore can control the alkali content of the finished product; in addition, controlling the caustic soda can improve the water resistance of the product.

The light-burning powder used in the biogas tank must have 4-7 hours of solidification time.The biogas tank has very strict requirements for the solidification speed of the light-burned magnesium oxide powder.If it is too fast, the stability is relatively poor. If it is too slow, the tank will deform easily.

88% light burnt magnesia powder, also known as deputy 90% light burnt magnesia powder, it has good water resistance. The positive 90 powder is afraid that the burnt product is too cooked, that is, it will work.

The main use of light magnesium oxide is for the production of rubber products neoprene adhesives. In the manufacture of rubber products, magnesium oxide plays the role of acid absorber accelerator, in the production of neoprene adhesives The effects of vulcanization crosslinking, anti-scorching agent resin chelation have been reached.

Magnesium oxide is also used in the manufacture of ceramics enamels. It plays a role in reducing the sintering temperature. It is used as a filler in the manufacture of grinding wheels paints. In addition, it is used in medicine, food processing, agriculture, electronics industry, insulation The materials industry has applications.
