Magnesium sulfate heptahydrate

Magnesium sulfate heptahydrate

1, Alias: Magnesium sulfate, also known as sulfur, bitter salt, diarrhea salt, Epsom salt.

Molecular formula: MgSO4.7H2O;

Relative molecular weight: 246.48; relative density of 1.68;

2. Characteristics: Industrial magnesium sulfate generally refers to magnesium sulfate 7 water, which is large, medium and small irregular particles, does not contain any toxic impurities, is odorless, bitter, easy to be deep in water, slightly soluble in alcohol, in air (dry The medium is easily weathered into a powder, and gradually removes the crystal water to become anhydrous magnesium sulfate when heated.

3 role

1) Agricultural application: Magnesium is the core element of chlorophyll, which can strengthen the plant reduction process, improve the disease resistance, promote the activation of enzymes, make the soil of the knotted loose and strong, develop the root system of the plant, fully absorb the nutrients, and make the plants more flourishing; Sulfur is the main component of proteins and enzymes in plants. It promotes root growth, enhances metabolism and redox in plants, and promotes crop growth and yield. Therefore, magnesium sulfate is an ideal raw material for the manufacture of compound fertilizer. It can be mixed with nitrogen, phosphorus and potassium to form compound fertilizer or mixed fertilizer according to different needs. It can also be mixed with one or more kinds of elements to form various fertilizers and photosynthetic fertilizers. After the actual fertilization experiment on nine fields of rubber trees, fruit trees, tobacco leaves, legumes, potatoes, and cereals, the magnesium-containing compound fertilizer can increase the crop by 15-50% compared with the magnesium-free compound fertilizer.

2), industrial applications: raw materials for the manufacture of zinc antimony powder and other zinc salts, also an important auxiliary material for viscose fiber and vinylon fiber, also used as wood and leather agents, bone gel clarification and protection agent and for electroplating, Flotation ore.

3), pharmaceutical applications: On the pharmaceutical, magnesium sulfate can be processed into laxatives, anticonvulsants, magnesium trisilicate, melamycin, acetylspiramycin and creatinine.

4) Feed application: Magnesium sulfate is a major additive in feed.

5) Printing and dyeing application: On printing and dyeing, magnesium sulfate can be used as dyeing agent, weighting agent and mordant on fabric.

6) Industrial wastewater treatment: Industrial production produces a lot of sewage. Magnesium sulfate can condense and settle the waste liquid sewage to meet the discharge standard.

Package: woven bag lined with plastic. Net weight 25kg, 50kg, 1000kg, 1250kg or according to customer needs.
