Sodium Sulfate (Yuanming Powder, Sodium Sulfate) is an inorganic sulfate with the chemical formula NA₂so₄ and a relative molecular weight of 142.04.Industrial grade sodium sulfate is odorless and has a slightly bitter taste. The substance is a white crystalline powder or granular form. Common forms include powdered, granular, anhydrous sodium sulfate (Yuanming powder), sodium sulfate decahydrate (Glauber's salt), no obvious odor, easy to absorb moisture and agglomeration, and easy to absorb moisture when exposed to air to form crystalline hydrates. It has strong stability, is not easy to decompose, and has excellent solubility.It is soluble in water, glycerin, and ethanol. It has excellent solubility, filling, dyeing and mold release properties. It is an indispensable basic raw material in many fields such as chemical industry, textiles, building materials, papermaking, detergents, and medicine.It melts when heated to 884℃, and exhibits excellent stability at high temperatures. It reacts mildly when in contact with most organic matter and acid-base substances, and has no obvious toxicity (it is strictly prohibited to eat, and skin contact needs to be cleaned in time to avoid inhalation of dust). It can be used in some pharmaceutical and food auxiliary fields (it must meet the corresponding grade standards). It needs to be sealed and stored in a cool, dry and well-ventilated warehouse, away from high temperature, humid environment and strong acid-base substances, to prevent moisture-absorbing agglomeration and dust flying, and ensure storage safety.It is mainly used as a co-solvent, filler, dye promoter, and mold release agent. It is widely used in the manufacture of detergents, textile printing and dyeing, glass, papermaking, chemical raw materials and other processes. It strictly follows the relevant standards of industrial chemicals and corresponding fields, and fits the current development trend of “refinement, specialization, greening, and scale” in the sodium sulfate industry. The core highlights its multi-field adaptability and product functionality.

Application Description

1. The textile industry is used as a core dye promoter and dye aid. It is mainly used in the printing and dyeing process of cotton, linen, chemical fiber and other textiles. It can improve the dyeing rate and dyeing uniformity of dyes, so that the dyed fabrics have bright colors and high color fastness. At the same time, it can be used as a water softener to remove impurities in the printing and dyeing water, optimize the printing and dyeing effect, strictly follow the textile industry raw material standards, and can be used in conjunction with various dyes and additives to further improve the quality of printing and dyeing products and adapt to the trend of high-end and green upgrading of the textile industry.
2. Detergents and daily chemicals are used as fillers and builders in the field of daily chemicals. They are used in the production of daily chemical products such as laundry detergent, laundry detergent, and detergent. As a filler, the product concentration can be adjusted and production costs can be reduced. As a lotion, it can enhance the decontamination capacity, dispersion and emulsification of detergents, reduce the amount of surfactants, and at the same time have the effect of resisting hard water. It is suitable for the large-scale production needs of the daily chemical industry and fits the development trend of green daily chemicals. Some high-end products can be used in cosmetic accessories (must meet the corresponding grade standards).
3. In the chemical industry, it is used as a basic raw material and a co-solvent for the production of chemical products such as sodium sulfide, sodium silicate, and ammonium sulfate. It can be used as a co-solvent to speed up the reaction rate and optimize the product preparation process. At the same time, it can be used in organic synthesis, electroplating and other processes, as an electrolyte to regulate the ph and conductivity of the system, adapt to the large-scale production needs of the electrochemicals and fine chemical industries, and meet the development trend of green chemicals. It is an indispensable basic raw material in the chemical industry chain.
4. In the field of papermaking, it is used as a cooking aid and a gluing agent. It is used in the cooking and gluing processes of papermaking. It can speed up the cooking speed of pulp, improve the yield of pulp, and reduce the consumption of cooking agents. At the same time, it can enhance the strength, water resistance and printing suitability of paper, make the surface of the paper flat, uniform texture, adapt to the needs of large-scale production such as cultural paper and wrapping paper, and help the paper industry save energy and reduce consumption and upgrade green.
5. In the field of building materials and glass, it is used as a flux and mold release agent for the production of glass, cement, ceramic tiles and other building materials products. As a flux, it can reduce the melting temperature of glass and cement, save energy, and optimize production efficiency. As a mold release agent, it can prevent building materials products from sticking to the mold and improve the appearance quality of the product. At the same time, it can enhance the hardness and wear resistance of building materials products, adapt to the needs of large-scale production of building materials, and meet the green and low-carbon development trend of the building materials industry. Some high-end products can be used in special glass production.
6. Used as excipients and additives in the pharmaceutical and food fields, pharmaceutical-grade sodium sulfate can be used to produce laxatives, electrolyte supplements and other products, which have the effect of laxative and electrolyte supplementation, and assist in the treatment of constipation and electrolyte disorders; food-grade sodium sulfate can be used as a food additive to regulate food taste, stabilize food properties, adapt to pharmaceutical and food production needs, strictly follow the safety standards of the pharmaceutical and food industries, and it is strictly prohibited to replace it with industrial-grade products.
7. It is used as a desiccant and water treatment agent in other industrial fields, and its moisture absorption characteristics can be used as an industrial desiccant for drying gases, liquids and solid materials; in the field of water treatment, it can be used as a coagulant and coagulant to remove suspended solids and impurities in the water, improve water quality, adapt to environmental protection treatment, industrial drying and other scenarios, and meet the development needs of large-scale environmental protection treatment industries. At the same time, it can be used as a feed additive (separately graded) to supplement the minerals needed for animal growth.
8. Note: This product is soluble in water and is strictly prohibited for consumption. Long-term skin contact needs to be protected and cleaned in time to avoid respiratory discomfort caused by inhalation of dust; corresponding grade products need to be selected in the fields of medicine, food, and cosmetics, and it is strictly prohibited to replace them with industrial grade products; waste disposal must follow industrial solid waste disposal standards to avoid random disposal and pollute the environment. After moisture absorption and agglomeration, it can be dried and crushed for normal use.
