| Conclusion | Qualified | |
It is mainly used as a filler for synthetic detergent. A cooking agent used in the paper industry to make kraft pulp.It is used in the glass industry instead of soda. Chemical industry used as raw materials for the manufacture of sodium sulfide, sodium silicate and other chemical products. The textile industry is used to prepare vinylon spinning coagulation bath. Used in the pharmaceutical industry as a laxative. Also used in nonferrous metallurgy, leather and other aspects.
Under normal conditions of use, sodium sulfate is generally relatively safe. The following points should be noted:
1. Avoid direct contact with sodium sulfate particles or solution and sensitive parts such as eyes and skin.
2. Avoid inhaling sodium sulfate dust or vapor, so as not to cause respiratory system irritation.
3. Wear protective gloves and safety glasses when handling sodium sulfate.
4. Avoid mixing with acidic substances to avoid harmful gases.
5. When storing and handling sodium sulfate, maintain good ventilation conditions to avoid fire sources.
