Application field of magnesium hydroxide

1. Magnesium hydroxide is an excellent flame retardant for plastic and rubber products. In terms of environmental protection, as flue gas desulfurizer, it can replace caustic soda and lime as neutralizer of acid containing wastewater. It is also used as oil additive to prevent corrosion and desulfurization. In addition, it can also be used in the refining of electronic industry, medicine and granulated sugar, as thermal insulation materials and manufacturing other magnesium salt products.


2. Magnesium hydroxide has excellent buffer performance, reaction activity, adsorption capacity and thermal decomposition performance. It can not only be used as chemical materials and intermediates, but also as a green environmental protection flame retardant and additive. It is used in polymer material industries such as rubber, plastics, fiber and resin. Magnesium hydroxide is mainly used as flame retardant, acid wastewater treatment agent, heavy metal remover and flue gas desulfurizer in the field of environmental protection.


3. The product can be used as flame retardant or flame retardant filler. It can be added to polyethylene, polypropylene, polystyrene and ABS resin. It has good flame retardant and smoke elimination effect. The addition amount is 40 ~ 20 phr.


However, anionic surfactants are required to treat the particle surface. Cheap anionic surfactants such as advanced fatty acid-base metal salts or alkyl sulfates and sulfonated succinate can be used, and the dosage is about 3%. It is also used in the manufacture of magnesium salt, refining of granulated sugar, pharmaceutical industry, daily chemical industry, etc.
