| Conclusion | Qualified | |
1. In the cleaning industry:
Sodium sulfate is used as a filler in the cleaning industry, especially in laundry detergent mixed with detergents. However, due to its harmful nature to the environment, it has been greatly limited.
2. Pulp production:
Sodium sulfate participates in Kraft cycle as an intermediate. Wood chips are heated with sodium sulfate to form sodium sulfite, which breaks cellulose bonds in the wood. So the wood scales become softer and more likely to form wood pulp.
3. In the textile industry:
Sodium sulfate is an ideal compound for textile dyeing because it does not corrode steel circuits and does not create cathodes on fabric fibers, so the dye can penetrate the fibers more efficiently and evenly. In Japan, sodium sulfate is widely used in the fabric manufacturing industry.
4. Glass production:
Sodium sulfate prevents the formation of residue from molten glass during the refining process, so it can also be used as a glass surface. Na2SO4 acts as a smoothing agent in molten glass production, removing small air bubbles and preventing the molten glass from bubbling during the refining process.
5. In the medical industry:
Sodium sulfate is one of the compounds we use as a laxative. At present, this sodium salt component is gradually being replaced by more complex substances. Sodium sulfate in medical treatment uses it as a compound to clean the intestines before applying certain procedures.
