Na2SO4 is an ideal compound for use in the textile dyeing industry, as it is non-corrosive to steel vessels while creating cathode on the fibers, so the dye is easily absorbed through the fibers more efficiently and evenly.
In the detergent industry and especially in the manufacturing of detergents, Na2SO4 is used as a filler. However, as it may be harmful to the environment, the use of Na2SO4 has been greatly limited.
In the pulp industry, Na2SO4 participates in the Kraft cycle as an intermediate. Wood flakes are heated with Sodium Sulfate to form Sodium Sulfite, which breaks the cellulose bonds present in the wood. As a result, the wood flakes become softer and can easily form wood pulp.
In the glass manufacturing industry, Sodium Sulfate is used as one of the main compounds… It can prevent scum formation by molten glass during the refining process and can also be used as a glass surface.
Sodium Sulfate acts as a smoothing agent in a molten glass, helping to remove small air bubbles and also preventing foaming of the molten glass during refining.
