The use of magnesium hydroxide

       Magnesium hydroxide is an excellent flame retardant for plastic and rubber products.

         Magnesium hydroxide is an excellent flame retardant for plastic and rubber products. As a flue gas desulfurizer in terms of environmental protection, it can replace caustic soda and lime as neutralizing agents for acidic wastewater. Also used as an oil additive, it has anti-corrosion and desulfurization effects. In addition, it can also be used for refining in the electronics industry, pharmaceuticals, sugar, as insulation materials, and in the manufacturing of other magnesium salt products.
          Magnesium hydroxide has excellent buffering performance, reactivity, adsorption capacity, and thermal decomposition performance. It can be used as a chemical material and intermediate, as well as a green and environmentally friendly flame retardant and additive in the polymer material industry such as rubber, plastic, fiber, and resin. Magnesium hydroxide is mainly used as a flame retardant, acid wastewater treatment agent, heavy metal removal agent, and flue gas desulfurization agent in the field of environmental protection.
          Magnesium hydroxide can be used as a flame retardant or flame retardant filler to be added to polyethylene, polypropylene, polystyrene, and ABS resins, with good flame retardancy and smoke suppression effects. The addition amount is 40-20 parts. But it is necessary to use anionic surfactants to treat the surface of particles. Affordable advanced fatty acid alkali metal salts or alkyl sulfate and sulfonated succinate anionic surfactants can be used, with a dosage of about 3%. This product is also used in the manufacturing of magnesium salts, refining of sugar, pharmaceutical industry, daily chemical industry, etc.
           It is necessary to carry out surface modification treatment on magnesium hydroxide to improve its compatibility with polymer matrix materials, so that the mechanical properties of the filling material do not decrease, and even improve some of the mechanical properties of the material.
           Magnesium hydroxide is insoluble in water and is a relatively weak alkali, but it is slightly irritating to the eyes, respiratory system, and skin. Therefore, appropriate protection should be taken when using, and gloves or goggles should be worn. In case of accidental contact with eyes, rinse immediately with plenty of water and seek medical attention. There is basically no corrosiveness.
