Sodium hydrosulfide ikoreshwa mu nganda zisiga amarangi nk'umufasha wo guhuza abahuza ibinyabuzima no gutegura amarangi ya sulfuru. Inganda zogosha zikoreshwa muguhumeka no gutunganya uruhu no gutunganya amazi yimyanda. Inganda zifumbire zikoreshwa mugukuraho monomer sulfure muri carbone desulfurizer ikora. Nibikoresho fatizo byo gukora ibicuruzwa byarangije igice cya ammonium sulfide na pesticide ethanethiol. Inganda zikora ubucukuzi zikoreshwa cyane mugushaka inyungu z'umuringa. Ikoreshwa mugusiga irangi rya sulfite mugukora fibre yakozwe n'abantu.

Ku isoko mpuzamahanga, sodium hydrosulfide ikoreshwa cyane cyane mu nganda nko gutunganya amabuye y'agaciro, imiti yica udukoko, amarangi, umusaruro w'uruhu hamwe na synthesis. Muri 2020, isoko ya sodium hydrosulfide ku isi yose ingana na miliyari 10.615 Yuan, umwaka ushize wiyongereyeho 2,73%. Kugeza ubu, umusaruro wa sodium hydrosulfide ngarukamwaka muri Amerika ni toni 790.000. Imiterere yimikoreshereze ya sodium hydrosulfide muri Reta zunzubumwe zamerika niyi ikurikira: icyifuzo cya sodium hydrosulfide ya kraft pulp kingana na 40% byicyifuzo cyose, flotation yumuringa igera kuri 31%, imiti n’ibicanwa bingana na 13%, na gutunganya uruhu bingana na 31%. 10%, abandi (harimo fibre yakozwe n'abantu na segpenol yo gusohora) bangana na 6%. Mu mwaka wa 2016, ingano y’isoko ry’inganda zo mu Burayi sodium hydrosulfide yari miliyoni 620, naho muri 2020 yari miliyoni 745, umwaka ushize wiyongereyeho 3,94%. Mu mwaka wa 2016, ingano y’isoko ry’inganda za sodium hydrosulfide y’Ubuyapani yari miliyoni 781 Yuan, naho muri 2020 yari miliyoni 845 Yuan, umwaka ushize wiyongereyeho 2.55%.

Nubwo uruganda rwa sodium hydrosulfide rwatangiye bitinze, rwateye imbere byihuse kandi ruba urwego rukomeye mu nganda z’ubukungu bw’igihugu cyanjye. Inganda za sodiyumu hydrosulfide zifite umwanya wingenzi mubukungu bwigihugu. Inganda za sodiyumu hydrosulfide irashobora guteza imbere ubuhinzi, inganda z’imyenda, inganda z’uruhu n’izindi nganda zijyanye nabyo; gutwara iterambere ry'ubumenyi n'ikoranabuhanga no kuzamuka mu bukungu bw'igihugu; gutanga no kwagura amahirwe yo kubona akazi.

Ukurikije GB 23937-2009 inganda za sodium hydrosulfide yinganda, sodium hydrosulfide yinganda igomba kuba yujuje ibi bikurikira:

Kuva mu mpera z'imyaka ya za 1960 kugeza hagati ya za 90, inganda za sodium hydrosulfide yo mu Bushinwa zateye imbere cyane kandi zihanga udushya mu bijyanye n'ibikoresho bitanga umusaruro, ikoranabuhanga n'ibicuruzwa byihariye. Mu mpera z'imyaka ya za 90, umusaruro wa sodium hydrosulfide wateye imbere kugeza ku rwego rwo hejuru rw'ikoranabuhanga. Anhydrous sodium hydrosulfide na sodium hydrosulfide ya kristalline yatejwe imbere kandi yinjira mubikorwa byinshi. Mbere, mugikorwa cyo gukora sodium hydrosulfide mugihugu cyanjye, wasangaga igipimo gito cyicyiciro cyihariye hamwe nibyuma birenze urugero aribibazo nyamukuru mubikorwa. Binyuze mu gukomeza kunoza imikorere yumusaruro, ubwiza bwibicuruzwa nibisohoka byiyongereye, kandi ibiciro nabyo byagabanutse cyane. Muri icyo gihe, hamwe n’igihugu cyanjye cyibanda ku kurengera ibidukikije, amazi y’imyanda ikomoka ku musaruro wa sodium hydrosulfide nayo yatunganijwe neza.

Kugeza ubu, igihugu cyanjye cyabaye igihugu kinini ku isi kandi kigakoresha sodium hydrosulfide. Nkuko ikoreshwa rya sodium hydrosulfide rigenda ritera imbere, ibyifuzo byayo bizaza kwaguka buhoro buhoro. Sodium hydrosulfide ikoreshwa mu nganda zisiga amarangi mu guhuza abahuza kama kandi nkumufasha wogutegura amarangi ya sulfuru. Inganda zicukura zikoreshwa cyane mu nyungu z’umuringa, mu gukora fibre yakozwe n'abantu yo gusiga irangi rya sulfite, n'ibindi. Nibikoresho fatizo byo gukora ibicuruzwa bitarangije igice cya ammonium sulfide na pesticide Ethyl mercaptan, kandi biranakoreshwa yo gutunganya amazi mabi. Impinduka zikoranabuhanga zatumye umusaruro wa sodium hydrosulfide ukura. Hamwe niterambere ryuburyo butandukanye bwubukungu hamwe n’irushanwa rigenda rirushaho gukaza umurego, iterambere ry’ikoranabuhanga mu musaruro wa sodium hydrosulfide rigabanya ibyinjira bishoboka kugira ngo bitange ibicuruzwa byiza kandi byiza.
