Cov ntawv thov ntawm Sodium Sulfide
Sodium sulfide siv dav hauv cov txheej txheem kev lag luam. Hauv kev lag luam zas xim, nws yog siv los tsim cov xim sulfur, xws li sulfur dub thiab sulfur xiav, nrog rau cov neeg sawv cev txo qis, mordants, thiab cov xim nruab nrab. Hauv cov hlau tsis yog ferrous, sodium sulfide ua haujlwm ua tus neeg sawv cev rau cov ores. Hauv kev lag luam tawv, nws yog siv ua tus neeg sawv cev depilatory rau cov tawv nqaij nyoos. Hauv kev lag luam ntawv, nws ua haujlwm ua tus neeg sawv cev ua noj. Sodium sulfide kuj tseem siv rau hauv kev tsim cov sodium thiosulfate, sodium polysulfide, sodium hydrosulfide, thiab lwm yam tshuaj sib xws. Hauv electroplating, nws yog siv rau hauv cyanide zinc plating, silver-cadmium alloy electrolyte solutions, thiab nyiaj rov qab. Tsis tas li ntawd, sodium sulfide yog siv dav hauv cov xim, roj hmab, thiab kev lag luam tshuaj txhua hnub, nrog rau kev kho dej.

Xaiv cov khoom siv raw zoo, kev tswj hwm zoo nruj thoob plaws hauv cov txheej txheem ntau lawm, xyuas kom ruaj khov rau txhua pawg ntawm sodium sulfide.
