Advantages Of Natural Sodium Sulphate

Natural sodium sulphate is free from the heavy metals such as arsenic, lead, zinc, chrome which are present in sulphate produced by chemical methods nor toxic minerals.

Against the slightly acidic chemically produced ones, the natural sodium sulphate has a pH value of 7-9 which indicates the absence of any acidity.

Production rate and prices are rather uniform, since the production doesn’t depend on any raw material.

These advantages make natural sodium sulphate preferable in pulp-paper and glass industries. And in the detergent industry, where sodium sulphate is used up to 40% by wt., the complete absence of toxic minerals and the neutral pH zone is of crucial importance.

Areas of utilization

Detergent

The principal use of sodium sulphate is in the detergent industry. Natural Sodium Sulphate is an ideal filler and diluent, as it is noncorrosive, neutral and cheap. The reduction of phosphate in the detergent as a result of the new air and water pollution in nearly all countries, has increased the consumption of sodium sulphate.

Pulp and Paper

Another significant use is in the kraft paper pulp. In this process sodium sulphate is reduced chemically to sulfide forms, which are the active constituents of the pulping liquor.

Glass

Glass industry is also one of the major industries that use large amounts of sodium sulphate. Nearly all modern glass factories have increased the amount of sodium sulphate in their formulations from the classical 0.5% up to 1.0% of the glass melt in a cheap and easy way.

Textile

Sodium sulphate aids in producing a more “level” color and better distribution of the dye on the fiber (improving the dye’s “standardization”), allowing for a more dilute but equally effective dye strength. Sulphate is specially used in the dyeing of wool.

Chemical Production

Furthermore, sodium sulphate can be used for the production of the chemicals such as potassium sulphate, alluminium sulphate, sodium silicate and sodium sulphur.
