Magnesium sulfate can be used for leather, paper, porcelain, fertilizer, and medical oral laxative.
Product properties: colorless, transparent acicular, granular or powder. The relative density is 1.67 ~ 1.71. Soluble in water, slightly soluble in ethanol, water solution is neutral, stable in humid air below 48.1℃, easy to weathering in warm dry air.
Application field:
1 Magnesium sulfate building materials
Magnesium sulfide cement has good fire resistance, heat preservation, durability and environmental protection, applied in fire door core board, external wall insulation board, silicon modified insulation board, fire prevention board and many other fields.
2 Industry
Used in leather, fertilizer, paper, porcelain, printing dye, lead-acid battery and other industries.
3 Magnesium sulfate agriculture
Fertilizer: In agriculture and horticulture, magnesium sulfate is used to improve soil deficient in magnesium (an essential component of the chlorophyll molecule). The advantage of applying magnesium sulfate over other magnesium sulfate soil amendments (such as dolomitic lime) is its high solubility.
4 Feed:
Feed grade magnesium sulfate as a supplement for magnesium in feed processing. Magnesium is an indispensable factor in the process of bone building and muscle contraction in livestock and poultry, as well as an activator of a variety of enzymes in livestock and poultry, and plays an extremely important role in substance metabolism and nervous function in livestock and poultry.
