Sodium hydrogen sulfide (NaHS) ndi sodium sulfide nonahydratendi mankhwala ofunikira omwe amagwira ntchito yofunika kwambiri m'mafakitale osiyanasiyana, makamaka popanga utoto, kukonza zikopa ndi feteleza. Mankhwalawa, omwe ali ndi nambala ya UN ya 2949, ndi ofunikira osati pamankhwala awo okha komanso pamagwiritsidwe awo ambiri.

M'makampani opanga utoto, sodium hydrogen sulfide imagwiritsidwa ntchito popanga organic intermediates komanso kupanga mitundu yosiyanasiyana ya sulfure. Utoto uwu umadziwika ndi mitundu yawo yowoneka bwino komanso zinthu zofulumira kwambiri, zomwe zimawapanga kukhala oyamba kusankha opanga nsalu. Kuthekera kwa NaHS kuchita ngati chochepetsera kumapangitsa kuti utoto ukhale wowala, kuwonetsetsa kuti mitundu siikhala yowoneka bwino komanso yokhalitsa.

Makampani a zikopa amapindulanso kwambiri ndi sodium sulfide. Amagwiritsidwa ntchito kwambiri pochotsa tsitsi ndi kuwotcha zikopa zaiwisi, kuzisintha kukhala zikopa zofewa. Kuphatikiza apo, NaHS imagwira ntchito yofunikira pakuwongolera madzi oyipa, kuthandiza kuchepetsa zinthu zovulaza ndikuwongolera madzi onyansa asanatulutsidwe m'chilengedwe.

Komanso, m'munda wa mankhwala feteleza, sodium sulfide ntchito kuchotsa monomer sulfure mu adamulowetsa mpweya desulfurizers. Njirayi ndiyofunikira kwambiri kuti musunge magwiridwe antchito a desulfurization system. Kuphatikiza apo, NaHS itha kugwiritsidwanso ntchito ngati zinthu zomaliza kupanga ammonium sulfide ndi mankhwala ophera tizilombo ethyl mercaptan, onse omwe ndi ofunikira kwambiri pantchito zaulimi.

Mwachidule, sodium hydrogen sulfide ndi sodium sulfide nonahydrate ndizofunikira kwambiri m'mafakitale osiyanasiyana ndipo zimathandizira kupanga utoto, zikopa ndi feteleza. Kusinthasintha kwawo komanso kuchita bwino kumawapangitsa kukhala omwe akutenga nawo gawo pakuwongolera zinthu zabwino komanso kusakhazikika kwachilengedwe.
