Sodium hydrosulfide imagwiritsidwa ntchito pamakampani opanga utoto ngati chothandizira popanga ma organic intermediates ndikukonzekera utoto wa sulfure. Malo otenthetsera zikopa amagwiritsidwa ntchito pochotsa tsitsi ndi kuwotcha zikopa komanso kuthira madzi otayira. Makampani a feteleza amagwiritsidwa ntchito kuchotsa sulfure ya monomer mu activated carbon desulfurizer. Ndiwopangira kupanga zinthu zomaliza za ammonium sulfide ndi ethanethiol mankhwala ophera tizilombo. Makampani opanga migodi amagwiritsidwa ntchito kwambiri popindula ndi mkuwa. Amagwiritsidwa ntchito popanga utoto wa sulfite popanga ulusi wopangidwa ndi anthu.

Pamsika wapadziko lonse lapansi, sodium hydrosulfide imagwiritsidwa ntchito kwambiri m'mafakitale monga kukonza mchere, mankhwala ophera tizilombo, utoto, kupanga zikopa ndi kaphatikizidwe ka organic. Mu 2020, msika wapadziko lonse wa sodium hydrosulfide kukula ndi 10.615 biliyoni ya yuan, kuwonjezeka kwa chaka ndi 2.73%. Pakali pano, kutulutsa kwapachaka kwa sodium hydrosulfide ku United States ndi matani 790,000. Kapangidwe ka sodium hydrosulfide ku United States ndi motere: kufunikira kwa sodium hydrosulfide ya kraft zamkati kumakhala pafupifupi 40% ya zomwe zimafunikira, kuyandama kwa mkuwa kumakhala pafupifupi 31%, mankhwala ndi mafuta amakhala pafupifupi 13%, ndipo Chikopa chimapanga pafupifupi 31%. 10%, ena (kuphatikiza ulusi wopangidwa ndi anthu ndi segphenol wa desulfurization) amawerengera pafupifupi 6%. Mu 2016, kukula kwa msika wamakampani aku Europe a sodium hydrosulfide kunali 620 miliyoni yuan, ndipo mu 2020 kunali 745 miliyoni yuan, kuwonjezeka kwa chaka ndi 3.94%. Mu 2016, kukula kwa msika wamakampani aku Japan a sodium hydrosulfide kunali 781 miliyoni yuan, ndipo mu 2020 kunali 845 miliyoni yuan, kuwonjezeka kwa chaka ndi 2.55%.

Ngakhale kuti bizinesi ya sodium hydrosulfide ya dziko langa inayamba mochedwa, yakula mofulumira ndipo yakhala gawo lofunika kwambiri pazachuma cha dziko langa. Makampani a sodium hydrosulfide ali ndi gawo lofunikira kwambiri pazachuma cha dziko. Makampani a sodium hydrosulfide amatha kuyendetsa chitukuko chaulimi, mafakitale a nsalu, mafakitale achikopa ndi mafakitale ena okhudzana; yendetsani kupita patsogolo kwa sayansi ndiukadaulo komanso kukula kwachuma cha dziko; kupereka ndi kukulitsa mwayi wa ntchito.

Malinga ndi GB 23937-2009 mafakitale sodium hydrosulfide muyezo, mafakitale sodium hydrosulfide ayenera kukwaniritsa mfundo izi:

Kuyambira kumapeto kwa zaka za m'ma 1960 mpaka pakati pa zaka za m'ma 1990, makampani opanga ma sodium hydrosulfide ku China apita patsogolo kwambiri komanso apanga zatsopano pankhani ya zida zopangira, ukadaulo komanso mawonekedwe azinthu. Chakumapeto kwa zaka za m'ma 1990, kupanga sodium hydrosulfide kwakula mpaka kufika paukadaulo wapamwamba kwambiri. Anhydrous sodium hydrosulfide ndi crystalline sodium hydrosulfide adapangidwa bwino ndikulowa mukupanga kochuluka. M'mbuyomu, popanga sodium hydrosulfide m'dziko langa, zidapezeka kuti kuchepa kwa kalasi yapadera komanso chitsulo chochulukirapo chinali mavuto akulu pakupanga. Kupyolera mu kuwongolera kosalekeza kwa njira yopangira, khalidwe la malonda ndi zotuluka zawonjezeka, ndipo ndalama zatsikanso kwambiri. Panthawi imodzimodziyo, ndikugogomezera dziko langa pachitetezo cha chilengedwe, madzi otayira opangidwa ndi sodium hydrosulfide adathandizidwanso bwino.

Pakalipano, dziko langa lakhala dziko lomwe limapanga komanso kugwiritsa ntchito sodium hydrosulfide. Pamene kugwiritsa ntchito sodium hydrosulfide kumapangidwa mosalekeza, kufunikira kwake kwamtsogolo kudzakula pang'onopang'ono. Sodium hydrosulfide imagwiritsidwa ntchito pamakampani opanga utoto kuti apange organic intermediates komanso ngati wothandizira popanga utoto wa sulfure. Makampani opanga migodi amagwiritsidwa ntchito kwambiri mu copper ore beneficiation, popanga ulusi wopangidwa ndi anthu kuti apange utoto wa sulfite, etc. Ndiwopangira kupanga zinthu zomaliza za ammonium sulfide ndi mankhwala ophera tizilombo ethyl mercaptan, ndipo amagwiritsidwanso ntchito. pochiza madzi oipa. Kusintha kwaukadaulo kwapangitsa kuti njira yopangira sodium hydrosulfide ikhale yokhwima. Ndi chitukuko cha mitundu yosiyanasiyana yazachuma komanso mpikisano woopsa kwambiri, kupita patsogolo kwaukadaulo kwa sodium hydrosulfide kupanga kumachepetsa zolowera momwe zingathere kuti apange zinthu zapamwamba komanso zambiri.
