Magnesium hydroxide is a white amorphous powder. Also known as caustic magnesite, light burned magnesia. Its suspension in water is called an emulsion. This product is colorless hexagonal crystal or white powder, insoluble in water and alcohol, soluble in dilute acid and ammonium salt solution, aqueous solution is slightly alkaline.
Its solubility in water is very small, but the dissolved part is ionized. The concentration of the saturated aqueous solution was 1.9mg/l(18°C). When heated to 350°C, the water is lost to form magnesium oxide. Brucite is a natural mineral that can be used in sugar, magnesium oxide, etc. Because the product is rich in content and chemically similar to aluminum, users began to use it instead of aluminum chloride to produce odor-clearing products. It is used as an analytical reagent and is also used in the pharmaceutical industry.
Application areas:
1. This product is an excellent flame retardant for plastic and rubber products. As a flue gas desulfurizer, it can replace caustic soda and lime as a neutralizing agent for acidic wastewater. It is also used as an oil additive to avoid corrosion and desulfurization. In addition, it can also be used in the electronics industry, sugar, as an insulating material and in the manufacture of other magnesium salt products.
2. Magnesium hydroxide has excellent buffering properties, reactivity, adsorption and thermal decomposition properties. It can not only be used as a chemical raw material and intermediate, but also as a green flame retardant and additive for rubber, plastic, fiber, resin and other polymer materials industry. Mainly used in the field of environmental protection flame retardant, acidic wastewater treatment agent, metal cleaning agent and flue gas desulfurization agent.
3. This product can be added to polyethylene, polypropylene, polystyrene and ABS resin as a flame retardant or flame retardant filler, and has good flame retardant and smoke suppression effects.
The treatment of the particle surface requires an anionic surfactant, such as an alkali metal salt of a fatty acid or an alkyl sulfate, a succinic acid sulfonate, and the like, in an amount of about 3%. The product is also used in magnesium salt manufacturing, sugar, pharmaceutical, cosmetic and other industries.
4, this product is also used in magnesium salt manufacturing, sugar, pharmaceutical, daily chemical and other industries. At the same time, the steam it releases can also play a role in suppressing smoke. The product is an excellent flame retardant in the rubber and plastics industries, with three functions of flame retardant, smoke suppression and filling.
5. Can be emulsified suspension used in medicine as acid preparation and laxative.
