Description
What is magnesium hydroxide?
Magnesium hydroxide is an inorganic substance with the chemical formula Mg (OH) 2. It is a white amorphous powder or colorless hexagonal columnar crystal, soluble in dilute acid and ammonium salt solutions, almost insoluble in water, and partially ionized in water. The aqueous solution is weakly alkaline. Heating to 350 ° C results in dehydration and the formation of magnesium oxide and magnesium hydroxide, a natural mineral called brucite, which can be used to produce sugar and magnesium oxide.

Q1: In which industries is magnesium hydroxide widely used?
A: In the rubber and plastic products industry, magnesium hydroxide is used as filler and flame retardant to improve the strength, aging resistance and flame retardancy of rubber and plastic products. Meanwhile, it also plays an important role in the fields of coatings, ceramics, glass products, sugar production, magnesium salt manufacturing, and more.
Q2: What are the advantages of magnesium hydroxide as a flame retardant in rubber and plastic products?
A: Magnesium hydroxide can significantly improve the flame retardancy of rubber products and reduce the risk of fire. Secondly, magnesium hydroxide can absorb a large amount of heat during combustion, reduce the combustion temperature, and thus slow down the spread of fire. In addition, it can also suppress the production of smoke and reduce toxic emissions from fires.
