Magnesium hydroxide has a wide range of uses. It is a new type of green and environmentally friendly inorganic flame retardant. It is a green inorganic flame retardant, a flue gas desulfurizer and a desulfurizer. It is also widely used as a treatment agent for acid and heavy metal wastewater. In addition, high-purity magnesium hydroxide is a high-quality and inexpensive raw material for the manufacture of industrial magnesium oxide, activated magnesium oxide, electro-fused magnesium oxide, electrical grade magnesium oxide, special magnesium oxide and other special materials.

电工级氧化镁

A complete set of high-purity magnesium hydroxide industrial technology and equipment, using sodium hydroxide and magnesium chloride as raw materials, by controlling the crystal morphology of magnesium hydroxide, reducing the entrainment of the filtration particle size mother liquor, reducing the energy consumption of drying magnesium hydroxide, improving product quality, and the average particle size of magnesium hydroxide The control is greater than 30µm, the filtration performance is good, the drying energy consumption of the product is low, the purity of magnesium hydroxide is over 99%, and the purity of magnesium oxide obtained by calcination is over 99.5%. At the same time, the sodium chloride solution produced by the process has high concentration (concentration greater than 25%) and low impurity content. It can be used as a raw material for the preparation of sodium hydroxide by chlor-alkali electrolysis, achieving zero discharge in the whole process.
