Sodium sulphide

Sulfide ne sodium (sodium sulphide fasaha) ne a fili wanda aka yadu amfani da masana'antu. Saboda haka, wannan abu da aka yi amfani da metallurgy, sunadarai, haske masana'antu da sauran masana'antu. Sodium sulphide, musamman, ake amfani a cikin yi na ɓangaren litattafan almara, dyes, a cikin aiki da fata. Abu da ake amfani a cikin narkewa na wasu wadanda ba ferrous karafa. Sodium sulfide ne ba makawa a filin daga hikimar tantance sunadarai. Ana amfani da a matsayin reagent a daban-daban tafiyar matakai.

A al'ada jiki Jihar al'amari ne dauke taro yi kama, cikinsa da high-ji na ƙwarai, ko hygroscopic lu'ulu'u. The abu samar a cikin wani nau'i na monolith 3 dabi'u a particulate form (a cikin nau'i na flakes ko granules). Aiwatar yarda samfurin ciwon haske-kasa-kasa, kodadde rawaya ko grayish launi.

Fasaha sodium sulfide Sin samarwa aka cushe a musamman bags for ashirin da biyar kilo. Marufi samar da kariya daga wanda bai kai ba hadawan abu da iskar shaka da kuma daukan hotuna zuwa haske. Bugu da ƙari, kamar yadda wani marufi karfe ganguna suna amfani na musamman ga sinadaran da samfurori, da kwantena (CK-1-5 (7)), ko kuma kamar yadda taushi kwantena ga guda amfani. The abu za a iya kunsasshen a takarda bags (lamba huɗu ko biyar-Layer) tare da wani ciki shafi - polyethylene jakar. A bags iya zama cikakken nauyi ba fiye da hamsin kilo.

Samfurin yawa ne 1,856 gram da cubic santimita. Narkewa zafin jiki ya kai 1180 digiri. A samfurin ne sosai hygroscopic. A ruwa a ashirin digiri narkar 13.6% a 97,5 digiri - 45% na kayan. A samfurin da yake iya kafa crystalline hydrates. Ga mai ruwa-ruwa mafita daga sodium sulfide fasaha halayyar alkaline dauki.
