Hexagonal flake-shaped magnesium hydroxide
Product Description
Introduction
Magnesium hydroxide is an important chemical product with the chemical formula Mg(OH)₂. It appears as colorless hexagonal columnar crystals or a white powder, and is almost insoluble in water. However, the small portion that does dissolve fully ionizes, resulting in a basic aqueous solution. It is soluble in dilute acids and ammonium salt solutions. Magnesium hydroxide is widely used as a flame-retardant filler in rubber and paint industries, as well as in chemical and environmental protection sectors.
Product Applications
Used as a flame-retardant material: It can serve as an insulating, high-temperature-resistant fireproof insulation material, offering the advantages of flame retardancy and lightweight properties.
Used as an additive: As an oil additive, it provides anti-corrosion and desulfurization effects.
For environmental applications: As a flue gas desulfurization agent, it can replace caustic soda and lime as a neutralizing agent for acid-containing wastewater. Additionally, when used as an industrial wastewater treatment agent, magnesium hydroxide’s large specific surface area and strong adsorption capacity make it highly effective at capturing and removing environmentally harmful heavy metal ions from industrial effluents.
