I-sodium hydrosulfide isetyenziswa kwishishini ledayi njengento encedisayo ekwenzeni i-organic intermediates kunye nokulungiselela idayi zesulfure. Umzi-mveliso wokwenza ulusu usetyenziselwa ukucheba iinwele kunye nokwenza ulusu lwesikhumba kunye nokucocwa kwamanzi amdaka. Ushishino lwesichumiso lusetyenziselwa ukususa i-monomer sulphur kwi-activated carbon desulfurizer. Yimathiriyeli ekrwada yokwenziwa kweemveliso ezigqityiweyo ze-ammonium sulfide kunye ne-ethanethiol yesibulali-zinambuzane. Ishishini lemigodi lisetyenziswa kakhulu ekuzuzeni ubhedu. Isetyenziselwa ukudaya i-sulfite ekuveliseni imicu eyenziwe ngabantu.

Kwimarike yehlabathi, i-sodium hydrosulfide isetyenziswa ikakhulu kumashishini afana nokusetyenzwa kweeminerali, izibulali-zinambuzane, iidayi, imveliso yesikhumba kunye ne-organic synthesis. Ngo-2020, ubungakanani bemarike yesodium hydrosulfide yi-10.615 yeebhiliyoni zeeyuan, ukunyuka konyaka-ngonyaka nge-2.73%. Okwangoku, imveliso yonyaka ye-sodium hydrosulfide e-United States yi-790,000 tons. Isakhiwo sokusetyenziswa kwe-sodium hydrosulfide e-United States ngolu hlobo lulandelayo: imfuno ye-sodium hydrosulfide ye-kraft pulp akhawunti malunga ne-40% yemfuno iyonke, i-akhawunti ye-copper flotation malunga ne-31%, iikhemikhali kunye ne-fuel account malunga ne-13%, kwaye ukusetyenzwa kwesikhumba kubalelwa malunga ne-31%. I-10%, abanye (kubandakanywa nemicu eyenziwe ngabantu kunye ne-segphenol ye-desulfurization) i-akhawunti malunga ne-6%. Ngo-2016, ubungakanani bemarike yoshishino lwe-sodium hydrosulfide yaseYurophu yayizizigidi ezingama-620 zeeyuan, kwaye ngo-2020 yayizizigidi ezingama-745 zeeyuan, ukonyuka konyaka ngonyaka nge-3.94%. Ngo-2016, ubungakanani bemarike yoshishino lwe-sodium hydrosulfide yaseJapan yayizizigidi ezingama-781 zeeyuan, kwaye ngo-2020 yayizizigidi ezingama-845 zeeyuan, ukonyuka konyaka ngonyaka nge-2.55%.

Nangona ilizwe lam ishishini le-sodium hydrosulfide liqale kade, likhule ngokukhawuleza kwaye libe licandelo leshishini eliyintsika kuqoqosho lwelizwe lam. Ushishino lwesodium hydrosulfide lukwindawo ebalulekileyo kuqoqosho lwelizwe. Ushishino lwesodium hydrosulfide lunokuqhuba uphuhliso lwezolimo, ushishino lwamalaphu, ishishini lesikhumba kunye namanye amashishini anxulumeneyo; ukuqhuba inkqubela phambili yenzululwazi nobuchwepheshe kunye nokukhula koqoqosho lwesizwe; ukubonelela kunye nokwandisa amathuba engqesho.

Ngokomgangatho we-GB 23937-2009 we-industrial sodium hydrosulfide, i-industrial sodium hydrosulfide kufuneka ihlangabezane nale migangatho ilandelayo:

Ukususela ekupheleni kwe-1960 ukuya phakathi kwe-1990, imboni ye-sodium hydrosulfide yaseChina iye yaphucula kakhulu kwaye yavelisa izinto ezintsha malunga nezixhobo zokuvelisa, iteknoloji kunye neenkcukacha zemveliso. Ngasekupheleni kwe-1990, ukuveliswa kwe-sodium hydrosulfide kuye kwaphuhliswa kwinqanaba eliphezulu lobuchwepheshe. I-anhydrous sodium hydrosulfide kunye necrystalline sodium hydrosulfide ziye zaphuhliswa ngempumelelo kwaye zangeniswa kwimveliso yobuninzi. Ngaphambili, kwinkqubo yokuvelisa i-sodium hydrosulfide kwilizwe lam, kwafunyaniswa ukuba izinga eliphantsi lebakala elikhethekileyo kunye nomxholo ogqithisileyo wesinyithi yizona ngxaki ziphambili kwimveliso. Ngokuphuculwa okuqhubekayo kwenkqubo yemveliso, umgangatho wemveliso kunye nemveliso iye yanda, kwaye iindleko nazo ziye zehla kakhulu. Kwangaxeshanye, ngokugxininiswa kwelizwe lam ekukhuselweni kwendalo, amanzi amdaka aveliswa yimveliso ye-sodium hydrosulfide nawo aphathwe ngokufanelekileyo.

Okwangoku, ilizwe lam liye laba ngumvelisi omkhulu wehlabathi kunye nomthengi we-sodium hydrosulfide. Njengoko ukusetyenziswa kwe-sodium hydrosulfide kuphuhliswa ngokuqhubekayo, imfuno yayo yexesha elizayo iya kwanda ngokuthe ngcembe. I-sodium hydrosulfide isetyenziswa kwishishini ledayi ukwenza i-organic intermediates kunye ne-agent encedisayo ekulungiseleleni idayi zesulfure. Ishishini lemigodi lisetyenziswa kakhulu kwi-copper ore beneficiation, ekuveliseni iintsinga ezenziwe ngabantu zokudaya i-sulfite, njl. njl yokucoca amanzi amdaka. Utshintsho lwezobuchwepheshe lwenze inkqubo yokuvelisa i-sodium hydrosulfide ikhule ngakumbi. Ngokuphuhliswa kweefom ezahlukeneyo zoqoqosho kunye nokhuphiswano olukhulayo, inkqubela yezobuchwepheshe yemveliso ye-sodium hydrosulfide inciphisa igalelo kangangoko kunokwenzeka ukuvelisa umgangatho ophezulu kunye neemveliso ezininzi.
