Sodium hydrosulfide, yomwe imadziwika kutiNaHS, ndi mchere wogwiritsidwa ntchito kwambiri wa sodium wopangidwa ndi mankhwala NaHS ndi nambala ya CAS 16721-80-5. Pagululi lili ndi nambala ya United Nations UN2949 ndipo imadziwika chifukwa cha ntchito zake zofunika m'mafakitale osiyanasiyana, makamaka mu mawonekedwe ake a 70%, omwe amapezeka mumitundu yonse yamadzimadzi komanso makonda.

Chimodzi mwazofunikira kwambiri za Sodium Hydrosulfide 70% ndi mumakampani opanga utoto, komwe amagwiritsidwa ntchito ngati chothandizira pakuphatikizika kwa organic intermediates komanso pokonza utoto wa sulfure. Ndikofunikira kwa opanga omwe akufuna kupanga mitundu yowoneka bwino, yokhalitsa muzovala.

M'makampani achikopa, sodium hydrosulfide ndi chinthu chofunikira kwambiri pakuchotsa zikopa komanso kufufuta. Ili ndi mphamvu yowola keratin ndipo ndiye chisankho choyamba cha opanga zikopa omwe amatsata zinthu zapamwamba zomalizidwa.

Kuphatikiza apo, sodium hydrosulfide imagwira ntchito yofunika kwambiri pakuyeretsa madzi oyipa, kuthandiza kuchepetsa zinthu zovulaza ndikuwongolera madzi abwino. Kagwiritsidwe ntchito kake kumafikiranso kumakampani a feteleza, komwe amagwiritsidwa ntchito kuchotsa sulfure wamba kuchokera ku activated carbon desulfurizer, kuwonetsetsa kuti pakupanga zoyeretsa.

Makampani opanga mankhwala ndi mankhwala ophera tizilombo amapindulanso ndi sodium hydrosulfide popeza ndizinthu zopangira zinthu zomaliza monga ammonium sulfide ndi ethyl mercaptan. Kuonjezera apo, m'makampani amigodi, amagwiritsidwa ntchito kwambiri mu copper ore beneficiation kuti apititse patsogolo ntchito yochotsa.

Pomaliza, Sodium Hydrosulfide imagwiritsidwa ntchito popaka utoto wa sulfite komanso kupanga ulusi wopangidwa ndi anthu, kuwonetsa kusinthika kwake komanso kufunikira kwake pakupanga kwamakono. Ndi mapangidwe ake apamwamba ndi ntchito zosiyanasiyana, 70% Sodium Hydrosulfide imakhalabe mankhwala ofunikira m'njira zosiyanasiyana za mafakitale, makamaka ku China, kumene amapangidwa ndi kusinthidwa kuti akwaniritse zosowa zenizeni.
