I-sodium hydrosulfide isetshenziswa embonini kadayi njengesisizi sokuhlanganiswa kwezinto eziphilayo kanye nokulungisa odayi besulfure. Imboni yokushuka isetshenziselwa ukususa izinwele kanye nokushukwa kwezikhumba kanye nokuhlanza amanzi angcolile. Imboni kamanyolo isetshenziselwa ukususa i-monomer sulphur ku-activated carbon desulfurizer. Yimpahla eluhlaza yokwenziwa kwemikhiqizo eqediwe kancane ye-ammonium sulfide kanye ne-pesticide ethanethiol. Imboni yezimayini isetshenziswa kakhulu ekuhlomuleni ithusi. Isetshenziselwa ukudaya kwe-sulfite ekukhiqizeni imicu eyenziwe umuntu.

Emakethe yomhlaba wonke, i-sodium hydrosulfide isetshenziswa kakhulu ezimbonini ezinjengokucubungula amaminerali, izibulala-zinambuzane, odayi, ukukhiqizwa kwesikhumba kanye nokuhlanganiswa kwe-organic. Ngo-2020, usayizi wemakethe ye-sodium hydrosulfide yomhlaba wonke ungama-yuan ayizigidi eziyizinkulungwane eziyi-10.615, okuwukunyuka konyaka ngo-2.73%. Njengamanje, umphumela wonyaka we-sodium hydrosulfide e-United States ungamathani angama-790,000. Isakhiwo sokusetshenziswa kwe-sodium hydrosulfide e-United States imi kanje: isidingo se-sodium hydrosulfide ye-kraft pulp sifinyelela cishe ku-40% wesidingo esiphelele, ama-akhawunti we-copper flotation cishe ama-31%, amakhemikhali kanye nezibaseli zibalelwa ku-13%, futhi ukucutshungulwa kwesikhumba kwenza cishe ama-31%. Amaphesenti angu-10, amanye (okuhlanganisa imicu eyenziwe umuntu kanye ne-segphenol ye-desulfurization) enza cishe u-6%. Ngo-2016, usayizi wemakethe wemboni ye-sodium hydrosulfide yase-Europe wawungama-yuan ayizigidi ezingama-620, kwathi ngo-2020 wawungama-yuan ayizigidi ezingama-745, okuwukunyuka konyaka ngo-3.94%. Ngo-2016, usayizi wemakethe womkhakha we-sodium hydrosulfide waseJapan wawungama-yuan ayizigidi ezingama-781, kwathi ngo-2020 wawungama-yuan ayizigidi ezingama-845, okuwukunyuka konyaka ngo-2.55%.

Nakuba imboni yezwe lami ye-sodium hydrosulfide yaqala sekwephuzile, ithuthuke ngokushesha futhi isibe umkhakha wemboni oyinsika ebalulekile emnothweni kazwelonke wezwe lami. Imboni ye-sodium hydrosulfide ithatha isikhundla esibalulekile emnothweni kazwelonke. Imboni ye-sodium hydrosulfide ingaqhuba ukuthuthukiswa kwezolimo, imboni yendwangu, imboni yesikhumba nezinye izimboni ezihlobene; ukushayela inqubekelaphambili yesayensi nezobuchwepheshe kanye nokukhula komnotho kazwelonke; ukuhlinzeka nokwandisa amathuba emisebenzi.

Ngokwezinga le-GB 23937-2009 le-industrial sodium hydrosulfide, i-industrial sodium hydrosulfide kufanele ihlangabezane nala mazinga alandelayo:

Kusukela ekupheleni kweminyaka yawo-1960 kuya maphakathi nawo-1990, imboni yaseChina ye-sodium hydrosulfide isithuthuke kakhulu futhi yasungula izinto ezintsha mayelana nemishini yokukhiqiza, ubuchwepheshe kanye nokucaciswa kwemikhiqizo. Ngasekupheleni kwawo-1990, ukukhiqizwa kwe-sodium hydrosulfide kuye kwathuthukiswa ezingeni eliphezulu lobuchwepheshe. I-anhydrous sodium hydrosulfide kanye necrystalline sodium hydrosulfide yenziwe ngempumelelo futhi yafakwa ekukhiqizweni ngobuningi. Ngaphambili, ekukhiqizeni i-sodium hydrosulfide ezweni lami, kwatholakala ukuthi izinga eliphansi lebanga elikhethekile kanye nokuqukethwe kwensimbi ngokweqile kwakuyizinkinga eziyinhloko ekukhiqizeni. Ngokuthuthuka okuqhubekayo kwenqubo yokukhiqiza, ikhwalithi yomkhiqizo kanye nokuphumayo kwenyukile, futhi izindleko nazo zehle kakhulu. Ngesikhathi esifanayo, ngokugcizelela kwezwe lami ekuvikelweni kwemvelo, amanzi angcolile akhiqizwa ukukhiqizwa kwe-sodium hydrosulfide nawo aphathwe ngokuphumelelayo.

Njengamanje, izwe lami selingumkhiqizi omkhulu emhlabeni wonke kanye nomthengi we-sodium hydrosulfide. Njengoba ukusetshenziswa kwe-sodium hydrosulfide kuthuthukiswa ngokuqhubekayo, isidingo sayo sesikhathi esizayo sizokhula kancane kancane. I-sodium hydrosulfide isetshenziswa embonini kadayi ukuze kuhlanganiswe izinto eziphilayo kanye njenge-ejenti eyisizayo yokulungisa odayi besulfure. Imboni yezimayini isetshenziswa kakhulu ekwenzeni i-copper ore beneficiation, ekukhiqizeni imicu eyenziwe umuntu yokudaya i-sulfite, njll. Iwumkhiqizo wokwenziwa kwemikhiqizo eqediwe ye-ammonium sulfide kanye ne-pesticide ethyl mercaptan, futhi iyasetshenziswa. yokuhlanza amanzi angcolile. Izinguquko zobuchwepheshe zenze inqubo yokukhiqiza i-sodium hydrosulfide ivuthwe kakhulu. Ngokuthuthukiswa kwamafomu ahlukahlukene ezomnotho kanye nokuncintisana okunamandla, inqubekelaphambili yezobuchwepheshe yokukhiqizwa kwe-sodium hydrosulfide kunciphisa okokufaka ngangokunokwenzeka ukuze kukhiqizwe imikhiqizo ephezulu kanye neminye.
