For environmental protection, magnesium chloride is used as a water purifier to treat wastewater, and I believe many customers know it. The water purifying agent uses polyaluminum chloride, polyferric chloride, polyacrylamide and magnesium chloride as raw materials, adds a certain proportion of fluorescent whitening agent and mixes uniformly into granular materials, and then carries out multi-weight packaging. Water quality, short time, less dosage, easy decomposition, no residual toxicity, no secondary pollution, removal of SS (suspended solids), CODcr (chemical oxygen demand), BOD5 (biochemical oxygen demand) total nitrogen and total phosphorus are obvious, do It provides a good foundation for water purification plants and drinking water purification in various environments.
Introduction of Magnesium Chloride:
Chemical Name: Magnesium Chloride (MgCl2) Chemical Description: The English name is magnesium chloride. The chemical formula MgCl2 is composed of 74.54% chlorine and 25.48% magnesium, with a relative molecular mass of 95.21. Colorless hexagonal crystals. Density 2.316-2.33 grams/cubic centimeter. Melting point 714 ℃. Boiling point 1412 ℃. Usually contains six molecules of crystal water, namely MgCl2•6H2O, which is easy to deliquescence, and will lose crystal water due to weathering in dry air. It is a monoclinic crystal with a salty taste and a certain corrosiveness. Its density is 1.569 g/cm3, melting point is 116-118℃, and it decomposes at the same time.
The shape of magnesium chloride: generally flake, block, crystal, granule and powder. The content is about 46% magnesium chloride hexahydrate, and 99% is anhydrous magnesium chloride. Chemical and physical properties of magnesium chloride: soluble in water and ethanol. Sensory indicators: white crystals, columnar or needle-like, with a bitter taste. Chemical formula MgCl2, colorless crystal, easily soluble in water, with bitter and salty taste. Usually contains 6 crystal waters, the density of MgCl2•6H2O is 1.56g/cm3, the melting point is 118℃, and it decomposes at the same time. Magnesium chloride is the raw material for electrolytic smelting of magnesium metal when heated, and it mainly comes from bittern of sun-dried sea salt.
