Product Name: Magnesium sulfate heptahydrate Molecular formula: MgSO4·7H2O Molecular weight: 246.47 is a white or colorless acicular or oblique columnar crystal, odorless, cool and slightly bitter, molecular weight: 246.47, specific gravity 1.68, easily soluble in water, soluble in its own crystal water at 67.5 ℃. Decomposed by heat, 70℃ to 80℃ is crystalline water that loses four molecules. Loss of all crystalline water to anhydrous matter at 200℃ a month. It is easily weathered into powder in air (dry), and the crystallized water is gradually removed when heated to anhydrous magnesium sulfate. Magnesium sulfate heptahydrate is easier to weigh than magnesium sulfate because it is not easy to dissolve. It is easy to quantify in industry. The nature of the product is orthorhombic. It is a four-corner granular or diamond crystal, colorless and transparent, and the aggregate is white, rose or green glass luster. The shape is fibrous, needle, granular, or powder. Odorless, cool, bitter and salty, relative density 1.67 ~ 1.71. Soluble in water, slowly soluble in glycerin, slightly soluble in ethanol, neutral aqueous solution, stable in humid air below 48.1℃, easy to weathering in warm dry air. Usage introduction: 1. Agricultural application: Magnesium sulfate can be used as a raw material for compound fertilizer. It can strengthen the plant reduction process, promote the activation of enzymes, make compacted soil loose and strong, promote root development, promote strong crop growth, and increase yield. 2. Industrial applications: used to make zinc barium powder and other zinc salts, it is also an important auxiliary material for viscose fiber and vinylon fiber. It is also used as wood and leather agent, bone gum clarification and protective agent, and electroplating, flotation ore. 3. Food application: In the food industry, magnesium sulfate can be used to make lactic acid, monosodium glutamate, etc. 4. Feed application: In feed, magnesium sulfate is a major additive and can be used as a supplement to magnesium in feed processing. 5. Printing and dyeing applications: In printing and dyeing, magnesium sulfate can be used as fabric dyeing agent, weighting agent, mordant. 6. Magnesium sulfate building materials: Magnesium sulfate cement has good fire resistance, heat insulation, durability and environmental protection. It is used in fireproof door core panels, exterior wall insulation boards, silicon modified insulation boards, fireproof boards and many other fields. 7. Industrial sewage treatment: Magnesium sulfate can condense and settle waste water to meet the sewage discharge standards.
