I-sodium hydrosulfide, eyaziwa ngokuba yiNaHS, ityuwa ye-sodium ye-sodium esetyenziswa ngokubanzi kunye ne-chemical formula NaHS kunye nenombolo ye-CAS 16721-80-5. Ikhompawundi inenombolo yeZizwe eziManyeneyo i-UN2949 kwaye yamkelwa ngokusetyenziswa kwayo okubalulekileyo kumashishini ahlukeneyo, ngakumbi kwifom yoxinaniso ye-70%, efumaneka kwiifom zombini kunye ne-customized flake form.

Esinye sezicelo eziphambili ze-Sodium Hydrosulfide 70% kumashishini edayi, apho isetyenziswe njengencedisi kwi-synthesis ye-organic intermediates kunye nokulungiswa kweedayi zesulfure. Sisithako esibalulekileyo kubavelisi abafuna ukuvelisa imibala edlamkileyo, ehlala ixesha elide kwilaphu.

Kwishishini lesikhumba, i-sodium hydrosulfide yinto eyimfuneko ekrwada kwinkqubo yokususwa kweenwele kunye nokusukwa kwesikhumba. Inekhono lokubola i-keratin kwaye lukhetho lokuqala lwabavelisi besikhumba abaphishekela iimveliso ezigqityiweyo eziphezulu.

Ukongeza, i-sodium hydrosulfide idlala indima ebalulekileyo kunyango lwamanzi amdaka, inceda ekunciphiseni izinto ezinobungozi kunye nokuphucula umgangatho wamanzi. Uluhlu lwesicelo lwayo lunabela kushishino lwesichumisi, apho lusetyenziselwa ukususa i-sulfure ye-elemental kwi-activated carbon desulfurizers, ukuqinisekisa inkqubo yokuvelisa ecocekileyo.

Amashishini amayeza kunye ne-pesticide nawo azuza kwi-sodium hydrosulfide njengoko iyimathiriyeli ekrwada yokwenza iimveliso ezigqityiweyo njenge-ammonium sulfide kunye ne-ethyl mercaptan. Ukongeza, kwishishini lemigodi, lisetyenziswa kakhulu ekuzuzeni intsimbi ekrwada ubhedu ukunyusa inkqubo yokukhutshwa.

Ekugqibeleni, i-Sodium Hydrosulfide isetyenziselwa ukudaya i-sulfite kunye nokuveliswa kweentsinga ezenziwe ngabantu, ebonisa ukuguquguquka kwayo kunye nokubaluleka kwimveliso yanamhlanje. Ngokuqulunqwa komgangatho ophezulu kunye nokusetyenziswa okuhlukeneyo, i-70% ye-Sodium Hydrosulfide ihlala iyikhemikhali ebalulekileyo kwiinkqubo ezahlukeneyo zoshishino, ngakumbi e-China, apho iveliswa kwaye ilungiselelwe ukuhlangabezana neemfuno ezithile.
