Magnesium oxide is an oxide of magnesium and is also an ionic compound.
Brucite is produced by the hydrolysis of soluble magnesium-containing compounds in a strong alkaline solution. It is a secondary change product of an alkaline solution acting on a magnesium silicate.
Because polymer synthetic materials are flammable and flammable, they bring great safety risks to people's lives. Therefore, in order to reduce the harm of such materials, flame retardants and flame retardant materials have gradually attracted people's attention.
Magnesium hydroxide is an inorganic flame retardant filler for polymer matrix composites with good application prospect.
Magnesium hydroxide in the magnesium hydroxide flame retardant, white amorphous powder. The suspension of magnesium hydroxide in water is called magnesium hydroxide emulsion, which is called magnesium emulsion, and the English name is Magnesset Hydroxide.
[Magnesia material] mainly magnesium-containing mineral-water-magnesite-stone
Filling type magnesium hydroxide is a new kind of flame retardant, through thermal decomposition releases combined water, absorb a large number of latent heat, in order to reduce its fill of synthetic materials in the surface temperature of flame, can inhibit polymer decomposition and the combustible gas generated by the effect of cooling.
Magnesium hydroxide flame retardant wood science, as a kind of flame retardant type magnesium hydroxide has been used widely now, and almost industry for the magnesium hydroxide flame retardant is also generally have basic understanding, so small make up or put some knowledge about magnesium hydroxide flame retardant with everyone share once.
The composition of magnesite often replace magnesium, iron, manganese, but the iron content of natural magnesite is generally not high. Magnesite crystal of trigonal system carbonate minerals, usually assumes the explicit or implicit crystalline grains density lump, which is also known as porcelain magnesite, white or grey, iron was yellow to brown, glass luster. With complete rhombohedron cleavage, porcelain shape magnesite with conchoidal fracture.
Brucite factory introduction at present, the domestic aluminum hydroxide dosage is more, but with the increase of temperature of the polymer processing, aluminum hydroxide is easy to decompose, reducing flame retardant effect
