            roduct description sodium sulfate sodium sodium sulfate chemical formula Na2SO4, also known as anhydrous Glauber's salt, anhydrous sodium sulfate inorganic compound, white, odorless, bitter crystal or powder, highly hygroscopic, sodium sulfate is easy to absorb water when it is exposed to the air. It is mainly used in making water glass, glass, porcelain glaze, paper pulp, refrigerant mixture, detergent, desiccant, dye thinner, analytical chemistry reagent, medicine, etc. .

           It is mainly used in coating field, glass field, ceramic field, plastic field, paper industry and so on. Glass Field: industrial sodium sulfate also has a large number of applications in the field of glass manufacturing. It can be used as a kind of glass whitening agent, which is of great significance for the manufacture of many transparent glasses. Adding a small amount of industrial sodium sulfate in the glass production process can make the glass have a higher transparency and gloss, and can keep the mechanical strength and stability of the glass. Ceramic Field: in ceramic manufacture, industrial sodium sulfate is widely used to adjust the viscosity of ceramic embryo and increase its adhesion. When industrial sodium sulfate is mixed with other additives, the toughness and hardness of the mixture can be increased. In addition, the use of industrial sodium sulfate in the surface coatings of ceramic products can improve the quality and gloss of the coatings. Paper industry: industrial sodium sulfate also plays an important role in paper industry. It can be used as a whitening agent to improve the quality of paper and improve the color of paper. At the same time, industrial sodium sulfate can also be used as a coating film-forming agent to prevent the transfer and overflow of paper in printing and wet

             The first production method (beach field method) makes use of the natural temperature changes in different seasons to make the water in the raw material liquid evaporate and crystallize the coarse Glauber's salt. Salt water containing sodium chloride, sodium sulfate, magnesium sulfate and magnesium chloride was poured into beach field in summer and evaporated by sunlight. This method is the main method to put forward mirabilite from natural resources. It has simple process and low energy consumption, but the working conditions are poor. Method 2(mechanical freezing method) the mirabilite was precipitated when the raw material was heated and evaporated by mechanical equipment and frozen to -5 ~ -10 ° C. Compared with beach method, this method is not affected by season and natural conditions. Good quality, but high energy consumption. Method 3(SALT L. comprehensive utilization method) is mainly used for sulfate-carbonate type salt water containing various components. The crude Glauber's salt is separated out while extracting various useful components. For example, for processing Salt L. Salt L. water containing sodium carbonate, sodium sulfate, sodium chloride, boride and potassium, bromine and lithium, the brine in Hong Kong can be carbonated first to convert sodium carbonate into Sodium bicarbonate crystals; The mother liquor was cooled to 5 ~ 15 ° C to crystallize borax, and the second mother liquor after separating borax was frozen to 0 ~ 5 ° C to precipitate mirabilite.
