750 to 1100 of the magnesite in high temperature of calcination is called "light burning", the product is called light burned magnesium, referred to as the light burning powder. The main purpose of the light burning powder as adiabatic and sound insulation of the building materials, manufacture of cementitious materials, it can also be used as ceramic raw materials.
Because of the light burning powder biogas tank will be long-term exposure to water, so the water resistance of the products is a special requirement, but also have good stability. The use of high content of light burned magnesia powder, for example: 88% the content of light burned magnesia powder. The ore selection using special low alkali burn ore can control the quantity of finished products, caustic soda; in addition, the control of caustic soda can improve the water resistance of products.
The solidification of the light burning powder must have 4-7 hours of time for methane tank, the solidification rate of the biogas tank light burned magnesia powder has very strict requirements, if it is too fast, the stability is relatively poor, if too slow, it is easy to deformation tank.
88% the content of light burned magnesia powder, which is 90% light burned magnesia powder, it has good water resistant. And it also afraid of burning 90 powder products are cooked, it is burned too.
The main purpose of light Magnesium Oxide is used for rubber and neoprene adhesive production, the production of rubber products, Magnesium Oxide played a role of acid absorption agent and accelerant, and in neoprene adhesive production plays a vulcanization, antiscorching agent and resin chelating effect.
Magnesium Oxide also has applications in the manufacture of ceramics and enamels. It plays a role in reducing the sintering temperature, as a filler in the manufacture of grinding wheels and paints. Besides that, it has been applied in medicine, food processing, agriculture, electronics industry, insulation material industry and so on.
