Manufacturer 99% Magnesium Sulphate MgSO4·7H2O Epsom Salt Bulk Magnesium Fertilizer Magnesium Sulphate Heptahydrate

Magnesium sulfate heptahydrate, also known as sulfur bitter, bitter salt, laxative salt, or laxative salt, has the chemical formula MgSO4 · 7H2O. It is a white or colorless needle shaped or slanted columnar crystal, odorless, cool, and slightly bitter. Magnesium sulfate heptahydrate decomposes under heat, gradually removing crystalline water and becoming anhydrous magnesium sulfate. It is mainly used for the manufacturing of fertilizers, leather making, printing and dyeing, catalysts, papermaking, plastics, ceramics, pigments, matches, explosives, and fire-resistant materials. It can be used for printing and dyeing thin cotton fabrics and silk, as a weighting agent for cotton silk and a filler for kapok products. It is also used as a laxative in medicine.

Application of of Magnesium Sulfate

1.In the electroplating industry, magnesium sulfate is used as a conductive salt: adding magnesium sulfate heptahydrate to the nickel plating solution can improve the conductivity of the plating solution, making the coating white and soft; It can also be used as an aluminum refining additive to color the aluminum surface.

2.In the environmental protection industry, magnesium sulfate heptahydrate is used directly as a sewage treatment agent or as a raw material for sewage treatment agents. It is used for industrial sewage treatment and has a coagulation and settling effect on waste liquid sewage, making it meet the discharge standards.

3. In the building materials industry, magnesium sulfate heptahydrate dissolves in water and reacts with heavy and light calcined powder (magnesium oxide) to form magnesium oxychloride cement. This cement has good insulation, fire resistance, durability, and environmental friendliness, and is used in the production of fireproof boards, exterior wall insulation boards, door core boards, etc.

4. In fire-resistant materials, magnesium sulfate heptahydrate is used as a flame retardant for plastics such as acrylic resin, epoxy resin, unsaturated polyester, and polyurethane, enhancing the heat resistance of fire-resistant materials.

5. In the pulp production of the papermaking industry, magnesium sulfate heptahydrate is used to increase the selectivity of oxygen bleaching for lignin removal, improve cellulose quality, and save product usage

6. Magnesium sulfate heptahydrate is used as a leather processing aid and filler, which can make leather softer, promote the adhesion between tanning agents and leather, improve leather quality, and enhance leather heat resistance.

7.In the printing and dyeing industry, magnesium sulfate heptahydrate can be used as a fabric dyeing agent, alkali resistant agent, weighting agent, and magnesium dyeing agent. It is used in the production of fine and thin cotton fabrics and silk, as well as in the chemical fiber and textile industries as a dyeing agent and reducing enzyme, ensuring uniform dyeing with a pH value between 6-7; It can also be used as a filler for kapok products and in the production of artificial silk.

8.In the chemical industry, magnesium sulfate heptahydrate is used as a raw material for manufacturing other magnesium salts such as magnesium stearate, magnesium hydrogen phosphate, magnesium silicate, magnesium oxide, and other sulfates such as potassium sulfate and sodium sulfate.
