Magnesium hydroxide can be used as a flame retardant, acid wastewater neutralizer, heavy metal wastewater precipitation agent, flue gas desulfurization agent and cosmetics and food additives, while magnesium hydroxide is an important raw material for the production of magnesium oxide. Especially as an inorganic flame retardant, it has high decomposition temperature, strong smoke suppression ability, good flame retardant effect, and no toxic and corrosive substances after decomposition, so it has been widely valued in various fields. Let's take a look at the usefulness of magnesium hydroxide in what aspects:

Magnesium hydroxide artificial non-polar flame retardant added to the polymer, the particle size distribution, morphology and purity of the polymer has a great influence. At present, the methods of producing magnesium hydroxide flame retardant include direct precipitation method, hydrothermal method, microwave synthesis method and precipitation boiling distillation method. In the actual industrial production, the use of a wide range of methods for direct precipitation and hydrothermal method, if you want to produce high-quality and special morphology of magnesium hydroxide products, often need these two methods combined with each other, can play a very good effect.

The precipitation process of magnesium hydroxide determines the quality of the product after hydrothermal water treatment, so it is of great significance to study the precipitation process of magnesium hydroxide.

Because magnesium hydroxide has strong adsorption force, high activity, good fluidity, easy pumping and storage, and convenient adjustment and control, it has great application in the environmental field. These applications include neutralization of industrial acid-containing wastewater, removal of heavy metals from industrial and mine emissions, flue gas desulfurization, land acid rain treatment, and pH adjustment. Magnesium hydroxide is also used in the manufacture of magnesium salt, refined sugar, pharmaceutical industry, daily chemical industry, etc. At the same time, the water vapor it releases can also be used as a smoke suppressant. Magnesium hydroxide is an excellent flame retardant with three functions of flame retardant, smoke suppression and filling in rubber and plastic industry. Emulsive suspensions of magnesium hydroxide are medically used as antacids and laxatives.
