How Is Sodium Sulfate Used In Industry?
Sodium sulfate has several industrial uses, including:
1. Detergent manufacturing: Sodium sulfate is used as a filler in powdered detergents to increase their bulk and improve their flow properties.
2. Glass manufacturing: Sodium sulfate is added to the mixture of raw materials used to make glass to lower its melting point and improve its workability.
3. Pulp and paper production: Sodium sulfate is used as a cooking chemical in the production of wood pulp for papermaking, helping to break down the fibers and separate the cellulose from the lignin.
4. Textile dyeing: Sodium sulfate is used as a leveling agent in textile dyeing, helping to ensure that the dye is evenly distributed across the fabric.
5. Chemical synthesis: Sodium sulfate is used as a source of sulfur in the production of various chemicals, such as sodium sulfide and sodium bisulfite.
Overall, sodium sulfate is a versatile compound with a wide range of industrial applications.
