Description: Magnesium sulfate, also known as sulfur bitter, bitter salt, cathartic salt and cathartic salt, is a compound containing magnesium. The appearance is colorless or white easily weathered crystal or white powder. Odorless. It tastes bitter and salty. Deliquescent. Magnesium sulfate heptahydrate loses six molecules of crystal water at 150 ℃ and all crystal water at 200 ℃. The density of anhydrous matter is 2.66, the melting point is 1124 ℃, and it decomposes at the same time. Soluble in water, soluble in alcohol, ether and glycerol, insoluble in acetone. Magnesium sulfate is a common chemical reagent and drying reagent, which is used in tanning, fertilizer, papermaking, porcelain, printing and dyeing and other industries. There are natural products. It can be prepared by the action of sulfuric acid on magnesium oxide, magnesium hydroxide or magnesium carbonate. Magnesium sulfate is an ideal raw material for manufacturing compound fertilizer. It can be mixed with nitrogen, phosphorus and potassium to form compound fertilizer or mixed fertilizer according to different needs, and can also be mixed with one or more elements to form various fertilizers and photosynthetic micro fertilizer. The fertilizer containing magnesium is most suitable for acid soil, peat soil and sandy land. Through the field fertilization comparison test of nine crops, such as rubber tree, fruit tree, tobacco leaf, beans, vegetables, potatoes and cereals, the compound fertilizer containing magnesium can increase the crops by 15-50% compared with the compound fertilizer without magnesium. In addition, it is used for industrial sewage treatment to coagulate and settle the waste water and sewage, so as to make it meet the sewage discharge standard.
Magnesium sulfate heptahydrate:Magnesium sulfate heptahydrate is an important inorganic chemical raw material, which is widely used. In the microbial industry, it is used as a medium component, a natural additive for brewing, magnesium to supplement brewing water and a nutrient source during fermentation; In light industry, it is used to produce stabilizer of calcium hydrogen phosphate in fresh yeast, monosodium glutamate, beverage, mineral water, health salt, sea crystal, bath health and beer and toothpaste; It is used as nutritional supplement, curing agent, flavor enhancer and processing assistant in food additives; In the chemical industry, it is used to manufacture magnesium stearate, magnesium hydrogen phosphate, magnesium oxide, other magnesium salts, potassium sulfate, sodium sulfate, etc; It can be used as alkali resistant agent, weighting agent and filler in printing and dyeing industry; Used as filling and reinforcing agent in leather industry; Used as conductive salt in electroplating industry, it can improve the conductivity of plating solution and make the coating white and soft; Used as aluminum smelting additive to color the aluminum surface; It can also be used as feed additive, cement coagulant aid, flame retardant, match, porcelain, glass, pigment and ABS resin; At the same time, it is also used in the field of paper industry and water treatment industry. In recent years, with the development of compound fertilizer industry, the demand for magnesium sulfate is increasing. It can improve the quality of compound fertilizer products and increase the medium elements of crops. It is an ideal additive for compound fertilizer.
1.Fertilizer use:Magnesium sulfate is used as a fertilizer in agriculture because magnesium is one of the main components of chlorophyll. It is usually used for potted plants or magnesium deficient crops, such as tomatoes, potatoes, roses, peppers and marijuana. The advantage of applying magnesium sulfate over other magnesium sulfate soil modifiers (such as dolomitic lime) is that magnesium sulfate has higher solubility than other fertilizers.
2.Feed use:Feed grade magnesium sulfate is used as magnesium supplement in feed processing.
3.use in the printing and dyeing industry, this product is used as the color developing salt of blue dye and alkali absorbing agent in black solution to ensure that the pH value is between 6 and 7 to achieve uniform dyeing. It can also be used as cement fire retardant, papermaking filler and weighting agent for textiles.
4.Uses: analytical reagent. desiccant.
5.Use desiccant. It is also used in tanning, fertilizer, papermaking, porcelain, printing and dyeing materials and other industries.
6.Use: used as raw material for manufacturing magnesium salt, feed additive, fertilizer, etc
7.Uses: used as analytical reagent, also used in printing and dyeing industry
8.Uses anhydrous magnesium sulfate is mainly used in feed additives as a supplement to trace element magnesium
