Magnesium hydroxide flame retardant

Magnesium hydroxide is a kind of flame retardant, its chemical formula is Mg (OH) 2, and it is a white amorphous powder. The molecular weight of Magnesium hydroxide is 400-700, which belongs to highly alkaline substances. Magnesium hydroxide is strongly alkaline and corrosive, and can absorb a large amount of water and carbon oxide to become sodium carbonate and water; It can also react with acids to form salts.
Because Magnesium hydroxide has strong hygroscopicity, is easily soluble in water and its aqueous solution is alkaline, it is often used to produce various chlorine containing bleaching agents, oxidants and detergents, and as an anti rust additive.
1. Industrial applications:
(1) Manufacturing bleaching powder: Calcium sulfate and limestone or marble are used as raw materials to produce quicklime (CaO), which is then reacted with water to obtain hydrated lime (CaO2 · H2O). Then, a proper amount of Magnesium hydroxide is added for neutralization reaction to obtain the bleaching powder product.
(2) Manufacturing Calcium oxide: Calcium oxide products are made from sodium carbonate and slaked lime by chemical reaction.
(3) Produce lightweight calcium carbonate products and chemical raw materials such as caustic soda, soda ash, ammonium chloride, etc.
(4) Used as a filler and reinforcing agent in the rubber industry.
(5) It is used as an intermediate of analytical reagent and Vitamin B12.
(6) Used as an antioxidant and preservative in the field of food processing.
2. Life applications:
(1) Dyeing aids and mordants that can be used in the textile printing and dyeing industry;
(2) Can be used as a filler and reinforcing material for paper sizing agents in the papermaking industry;
(3) It can be used as a degreasing and degreasing treatment solution for metal cleaning, and can be used as a corrosion inhibitor and metal anti-corrosion agent;
(4) It can also be used as raw material for preparing antipyretic Analgesic acetyl Anilinium chloride in the pharmaceutical industry;
(5) A coloring promoter that can be used in the plastic processing industry;
(6) It can also be used as a bonding promoting component for paint thinner and wood fireproof board bonding material;
(7) It can also be used as a milky white dispersion for ceramic glaze coatings;
(8) It can also be used for making fireproof and insulation layers in refractory materials.
3. Agricultural applications:
(1) Can be used as an additive for soil amendment:
(2) Additives that can be used as pesticide synergists:
(3) Additives that can be used as fertilizer enhancers:
(4) It can also be used to prevent and control plant diseases and pests, and so on!
