What do you know about magnesium hydroxide？
Magnesium hydroxide can be used as flame retardant, acid wastewater neutralizer, heavy metal wastewater precipitator, flue gas desulfurizer, cosmetics and food additives, and is also an important raw material for the production of magnesium oxide. Especially as an inorganic flame retardant, magnesium hydroxide flame retardant has been widely used in various fields because of its high decomposition temperature, strong smoke suppression ability, good flame retardant effect and no toxic and corrosive substances after decomposition. So what else are the characteristics of magnesium hydroxide? Let's find out together:
When the inorganic flame retardant of magnesium hydroxide is added to the polymer, its particle size distribution, morphology and purity have a great influence on the properties of the polymer. At present, there are direct precipitation method, hydrothermal method, microwave synthesis method and precipitation boiling distillation method to produce magnesium hydroxide flame retardant.
In the actual industrial production, if we want to produce magnesium hydroxide products with high quality and special morphology, it is necessary to combine precipitation method and hydrothermal method to achieve good results. The precipitation process of magnesium hydroxide determines the quality of products after influent heat treatment, so it is of great significance to study the precipitation process of magnesium hydroxide.
Magnesium hydroxide is widely used in neutralization of industrial acid-containing wastewater, removal of heavy metals from industrial and mine discharges, flue gas desulfurization, land acid rain treatment and PH regulation because of its strong adsorption and activity. It is also used in the manufacture of magnesium salt, refining of sugar, pharmaceutical industry, daily chemical industry and so on. In addition, magnesium hydroxide is an excellent flame retardant with triple functions of flame retardant, smoke suppression and filling in the rubber and plastic industry.
