Application
Industry:
1.Chemical industry: It is the 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.
2.Environmental protection industry: used directly as a sewage treatment agent or as a raw material for sewage treatment agents, used for industrial sewage treatment, and has a coagulation and sedimentation effect on waste liquid and sewage.
3.Building materials industry: After dissolving in water, it reacts with heavy light burned 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, magnesium sulfate boards, etc.
4.Construction industry: used as a coagulant aid for cement.
Polymer materials industry: used as a polymer emulsion coagulant in the industrial production of polymer materials such as ABS and EPS.
5.Artificial fiber industry: It is a component of spinning baths and an important auxiliary material for viscose fibers and vinylon fibers.
6.Paper industry: Used in pulp production to increase the selectivity of oxygen bleaching for lignin removal, improve cellulose quality, and save product usage.
7.Leather industry: As a processing aid and filler, it can make leather softer, promote the adhesion between tanning agents and leather, improve the quality of leather, and enhance the heat resistance of leather.
8.Printing and dyeing industry: It can be used as a fabric dyeing agent, alkali resistant agent, weighting agent, magnesium dyeing agent, for 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 reductase to ensure 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.
9.Electroplating industry: used as a conductive salt, adding magnesium sulfate heptahydrate to nickel plating solution can make the plating solution have good conductivity, making the coating white and soft; It can also be used as an additive in aluminum refining to color the surface of aluminum.
10.Microbial industry: used as a component of culture media, additive for brewing, magnesium supplement for brewing water, and nutrient source during fermentation.
11.Light industry: used as a stabilizer for calcium hydrogen phosphate in the production of fresh yeast, monosodium glutamate, beverages, mineral water, health salts, sea crystals, shower gels, "Burton" type beer, and toothpaste
