Magnesium hydroxide can be used as a flame retardant, an acidic wastewater neutralizer, a heavy metal wastewater precipitant, a flue gas desulfurizer, a cosmetic and a food additive, and magnesium hydroxide is also an important raw material for producing magnesium oxide. In particular, when it is used as an inorganic flame retardant, it has a high decomposition temperature, a strong smoke suppressing ability, a good flame retarding effect, and does not cause toxic and corrosive substances after decomposition, and has been widely recognized in various fields. Let's take a look at the use of magnesium hydroxide:
Magnesium hydroxide artificial infinite flame retardant is added to the polymer, and its particle size distribution, morphology and purity have a great influence on the performance of the polymer. At present, methods for producing magnesium hydroxide flame retardant include direct precipitation method, hydrothermal method, microwave synthesis method, and precipitation boiling distillation method. In actual industrial production, a wide range of methods are used for direct precipitation and hydrothermal methods. If high-quality and special-morphic magnesium hydroxide products are to be produced, it is often necessary to combine these two methods to achieve excellent results.
The precipitation process of magnesium hydroxide determines the quality of the product after treatment with water and hot water, so it is of great significance to study the precipitation process of magnesium hydroxide.
Due to its strong adsorption capacity and high activity, magnesium hydroxide has non-sedimentation and non-cohesive properties. It also has good fluidity and is easy to pump and store. It is easy to adjust and control. The characteristics, therefore, have great applications in the environmental field. These applications include neutralization of industrial acid-containing wastewater, removal of heavy metals from industrial emissions and mine emissions, flue gas desulfurization, land acid rain treatment, and pH regulation. Magnesium hydroxide is also used in the manufacture of magnesium salts, the refining of sugar, the pharmaceutical industry, and household chemicals. At the same time, the water vapor it emits 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 the rubber and plastics industry. The milky suspension of magnesium hydroxide is medically used as an antacid and a laxative.
