Introduction to Magnesium Hydroxide
Magnesium hydroxide, with the chemical formula Mg(OH)₂, is an inorganic compound. It is a white, odor - less powder that is sparingly soluble in water. Magnesium hydroxide has a wide range of applications in various industries.
In the environmental field, it is widely used in wastewater treatment as a neutralizing agent. It can effectively neutralize acidic wastewater, remove heavy metals, and reduce the chemical oxygen demand (COD) and biological oxygen demand (BOD) of the water. In the pharmaceutical industry, it is a common ingredient in antacids due to its ability to neutralize stomach acid and relieve symptoms such as heartburn and indigestion.
In the field of flame retardancy, magnesium hydroxide is an important inorganic flame retardant. When added to polymers such as plastics, rubbers, and textiles, it can decompose endothermically during combustion, absorbing heat and releasing water vapor, which dilutes the concentration of flammable gases and inhibits the spread of fire.
Now, let's take a look at the top 10 magnesium hydroxide factories in China.
