Hebei Messi Biology Co., Ltd. stated that magnesium hydroxide is known as a green and safe neutralizer, an environmentally friendly flame retardant and the third alkali. It is the third magnesium chemical in magnesium chemicals after magnesia and light-burned magnesium oxide. It is also one of the products favored and respected by developed countries in the process of implementing sustainable development strategies, protecting the environment, and beneficial ecological development. Among them, slurry magnesium hydroxide is widely popular due to its low production cost (compared with solid powder), safe operation, easy use and no secondary pollutants.
Slurry magnesium hydroxide has developed rapidly in developed countries such as the United States and Japan. The total annual consumption of slurry magnesium hydroxide in the United States is 200,000-300,000 tons, of which 120,000-140,000 tons are used to neutralize acidic wastewater, and there is still a trend of further growth. At the same time, slurry magnesium hydroxide also has the characteristics of high activity, no sedimentation, easy flow, and pumpability. In China, slurry magnesium hydroxide is also increasingly valued. Hebei Messi Biology Co., Ltd. reviewed the application and preparation method of slurry magnesium hydroxide.
Advantages of slurry magnesium hydroxide:
(1) The raw material of slurry magnesium hydroxide comes from seawater, which is abundant;
(2) Slurry magnesium hydroxide has buffering properties. No matter what kind of acid is neutralized, its pH value does not exceed 9;
(3) Slurry magnesium hydroxide does not form scaling substances when used as a neutralizer, which is convenient for operation and management;
(4) Slurry magnesium hydroxide has high activity and strong adsorption capacity. It can adsorb various heavy metal ions in acidic liquid while neutralizing it, thereby achieving the purpose of removal;
(5) Slurry magnesium hydroxide [containing Mg(OH)2, 30%-45%] has non-sedimentation, non-coagulation and good fluidity, and is easy to pump and store, and is convenient to use and adjust;
(6) It is non-corrosive and does not require special anti-corrosion equipment for disposal;
(7) It is safe, non-toxic and harmless, and is a “green and safe neutralizer”.
