25KG/ BAGSSSodium Sulphate CAS 7757-82-6 Used for Making Paper
Sodium sulfate (chemical formula: Na₂SO₄) is an inorganic salt composed of the elements sodium, sulfur, and oxygen. It is white powder, soluble in water, with hygroscopicity. When sulfur is dissolved in water, its aqueous solution is mostly neutral. Instability: In the chemical synthesis laboratory, sodium sulfate is a more commonly used post-treatment desiccant, which is easy to absorb water when exposed to air and generate sodium sulfate decahydrate, also known as salt water, which is alkaline. Flammability: upstream raw materials include sulfuric acid, caustic soda, etc. Reactivity: Sodium sulfate is a strong acid and alkali salt containing oxic acid, which can react with some substances. For example, sodium sulfate reacts with barium chloride to form a barium sulfate precipitate and sodium chloride; Sodium sulfate reacts with some chemicals and is used to make certain chemical compounds.

1. Detergent: Sodium sulfate is often used as an additive in detergents to help remove stains and oil stains because of its better water solubility and adsorption.
2. Agricultural fertilizer: Sodium sulfate can be used as a raw material in agricultural fertilizer for the production of complex fertilizers such as ammonium sulfate and potassium sulfate. These fertilizers play an important role in improving the yield and quality of crops.
3. Industrial use: In industry, sodium sulfate is widely used in glass, paper, petroleum, chemical and other fields. For example, in glass manufacturing, sodium sulfate can be used as a clarifying agent to help remove impurities and improve the transparency of the glass.
4. Other uses: In addition to the above uses, sodium sulfate is also used in printing and dyeing, leather, food and other fields. For example, in the printing and dyeing industry, sodium sulfate can be used as a mordant to help improve the coloring effect of dyes. In leather manufacturing, sodium sulfate can be used to treat leather to make it softer and smoother. In addition, in the food industry, sodium sulfate is also used as additives such as preservatives and thickeners
