Messi Biology adopts the method of producing high-purity nano magnesium oxide from magnesite of Lake Bango in Nagqu, Tibet, this method utilizes the principle of chemical reaction, first of all, the magnesite will be calcined to obtain magnesium oxide, react with sulfuric acid, filtered to obtain magnesium sulfate solution, using neutralizing agent as well as oxidizing agent, purification of the solution, to obtain the purified magnesium sulfate solution, a part of it, add ammonium bicarbonate with surfactant , calcined to obtain high-purity nano-magnesium oxide; In the other part, the filtrate containing ammonium sulfate obtained from the previous step is heated and decomposed with light burnt powder to obtain flame retardant grade magnesium hydroxide, which is filtered in the reactor to obtain environmentally friendly grade magnesium hydroxide, and the filtrate is reused without emission.
Fibrous magnesium hydroxide, alkaline magnesium carbonate and high purity nano magnesium oxide, widely used in rubber and plastic products for flame retardant, smoke suppression, filling and reinforcing; also can be used as adiabatic, high temperature insulation materials; also can be used in the manufacture of optical glass, electronic ceramics, 5G electronic components, aerospace and other fields.
Water magnesite mineral is a unique mineral resource of Bango Tso Lake in Nagchu area of Tibet, which is a kind of natural alkaline magnesium carbonate, with rich resource reserves, simple mining technology and clean mining process. Based on the water magnesium mineral, we can develop low-smoke and halogen-free mineral-based flame retardant materials, industrial discharge sewage treatment agents, industrial desulfurization/sulfur fixing agents, smoke suppressants, inorganic mineral-based fillers, humidification and deodorization of new wall materials and other environmentally friendly products. Hebei magnesium Xi Biological Co., Ltd. relying on the water magnesite resources of Nagchu Bango wrong lake in Tibet, development, manufacture and sales of water magnesite various magnesium salt series products.
