1. Sodium sulfate yog ib qho tseem ceeb raw khoom rau ua iav thiab ntawv. Nws yog siv feem ntau hauv papermaking thiab cellulose kev lag luam.
2. Sodium sulfate yog ib feem ntawm cov khoom siv hluavtaws. Ntxiv nws tuaj yeem txo qhov nro ntawm qhov chaw thiab ua kom cov solubility ntawm detergent. Nws kuj yog ib qho kev sib tw ntawm cov dyes, ib qho pab rau dyeing, printing thiab dyeing, ib tug dye promoter rau ncaj dyes, sulfur dyes, vat dyes thiab lwm yam paj rwb fibers, thiab ib tug dye retarder rau txhob lo lo ntxhuav dyeing nrog ncaj dyes.
3. Hauv kev lag luam tshuaj, sodium sulfate yog siv los ua raw khoom rau kev tsim sodium sulfide, gypsum, sodium silicate thiab lwm yam khoom siv tshuaj.
4. Sodium sulfate cryogen feem ntau yog siv hauv chav kuaj. Hauv tshuaj, mirabilite yog siv los ua laxative. Sodium sulfate yog tshuaj tua kab mob rau barium thiab lead lom.
