Magnesium sulfate heptahydrate is a magnesium compound,Inorganic Compound also known as diarrhea salt, sulfur bitter, diarrhea salt, fork type MgSO4 · 7H2O, Inorganic Compound the relative molecular mass of 246.47, white or colorless small oblique and oblique columnar crystals, Odorless, cool and slightly bitter, soluble in water, slightly soluble in ethanol, stable in humid air below 48.1 ℃, easy to weather in warm dry air; Inorganic Compound above 48.1 ℃, lost a crystal water, become Magnesium sulfate hexahydrate, and with the temperature changes will gradually remove the crystallization of water into anhydrous magnesium sulfate. Magnesium sulfate heptahydrate is an important inorganic chemical products,Inorganic Compound uses a very wide range, can be used in industry, agriculture, food, medicine and other industries.
1, feed grade magnesium sulfate heptahydrate can be used as feed additives in the magnesium, magnesium sulfate is a very important fertilizer, because it can provide a rich nutrition for the crops;
2, medical grade magnesium sulfate heptahydrate can be used for cathartic, its saturated solution topical coating, anti-inflammatory, swelling, detoxification, analgesic effect, and inhibit the central nervous system, the role of anti-spasm;
3, industrial grade magnesium sulfate heptahydrate can be used for printing and dyeing thin cotton cloth, cotton, silk weighting agent, wood products, filler; industrial wastewater treatment, waste water into a condensate and sedimentation to make it to the sewage standards.
4, in the microbial industry, magnesium sulfate heptahydrate can be used as medium ingredients, brewing additives, add boiling water magnesium, do the nutrient source when fermentation.
5, magnesite industry, magnesia cementitious material in a - magnesium sulfide cement, it is to magnesium sulfate as the main raw material, so that magnesium sulfate solution into magnesium sulfide cement as one of the varieties of modifier. With magnesium sulfate and magnesium oxide mixed stirring, the formation of magnesium glued material products.
The quality of this sulfur magnesium should meet the requirements of HG / T 2680-2009, and its appearance quality should meet the requirements of 5.1 in HG / T 2680-2009. Inorganic Compound This standard specifies the requirements, test methods, inspection rules, marking, labeling, packaging, transportation and storage of industrial magnesium sulphate.
The presence of water in cells is free water and combined water, combined with water and other substances, is an important component of cell structure, Inorganic Compound accounting for about 4.5%; free water in the form of free, is a good cell solvent, Can also be directly involved in biochemical reactions, Inorganic Compound but also transport nutrients and waste. All in all, all living activities of various organisms are inseparable from water.
Most of the inorganic salts in the presence of ionic state, Inorganic Compound although its content is very small, but there are many important role: some inorganic salts are some important components of intracellular compounds, such as Fe is the main component of hemoglobin, Inorganic Compound Mg Is a necessary component of chlorophyll molecules; many inorganic salt ions for the maintenance of cells and organisms have an important role in life activities, Inorganic Compound such as blood calcium content is too low will appear convulsions; inorganic salts for maintaining cell acid and alkali balance is also important The
