Cov khoom lag luam sodium sulfide tau muab faib ua ob pawg raws li kev tsim khoom

Anhydrous sodium sulfide yog daj ntseg daj nkig khoom nrog muaj zog hygroscopicity. Nws yog soluble hauv dej thiab siv dav hauv kev lag luam xws li tshuaj lom neeg kev lag luam, kev ua ntxhia, tawv tanning, thiab kev kho dej khib nyiab. Nws yog feem ntau siv rau precipitating hnyav hlau thiab ua ib tug sulfiding neeg sawv cev, thiab yog ib tug nquag siv inorganic tshuaj raw khoom.

Txheej txheem:Qeb 1 yog tsawg- hlau sodium sulfide (feem ntau hu ua daj alkali); Qeb 2 yog sodium sulfide zoo tib yam (feem ntau hu ua liab alkali)

Qhov tsos:flakes, xim av liab los yog daj.

Kev siv tseem ceeb:Siv dav hauv kev lag luam sulfur dyes, ntawv ua, tawv tanning, ntxhia ua thiab lwm yam lag luam
