Sodium hydrosullfide, yemwe amadziwika kutiNawa, imagwiritsidwa ntchito kwambiri mchere wamphamvu kwambiri wokhala ndi ma nahs a Nahs ndi nambala 16721-80-5. Pawiri ili ndi United Nations nambala ya2949 ndipo imadziwika kuti ndi yofunika kwambiri pamafakitale osiyanasiyana, makamaka mu mawonekedwe a 70% amadzimadzi.

Chimodzi mwazinthu zofunika kwambiri za sodium hydrosulffide 70% ali mu utoto, komwe amagwiritsidwa ntchito ngati othandizira pazapakati ndi pokonzekera utoto wa sulufule. Ndi gawo lofunikira kwa opanga omwe akuyang'ana kuti apange mitundu yokhazikika, yosatha m'malemba.

M'mpani ya zikopa, sodium hydhilfide ndi zinthu zosafunikira mu nthawi yaiwisi kubisala ndikupindika. Ikutha kuwombera Keratin ndipo ndiye chisankho choyambirira cha opanga chikopa chotsatira zinthu zapamwamba kwambiri.

Kuphatikiza apo, sodium hydrosuul amagwira ntchito yofunika kwambiri mu mankhwalawa amadzi, kuthandiza kusintha zinthu zovulaza ndikusintha madzi. Ntchito zake zimafalikira zimafikiranso kwa makampani a feteleza, pomwe imagwiritsidwa ntchito kuchotsa sulfur wosangalatsa kuchokera ku zisudzo zokhazikitsidwa, ndikuwonetsetsa kupanga.

Mafakitale ogwiritsa ntchito mankhwala osokoneza bongo komanso mankhwala amapindulanso ndi sodium hydrosuul chifukwa chopangira zinthu zomaliza monga momwe ammonium sulpide. Kuphatikiza apo, popanga mini mini, imagwiritsidwa ntchito kwambiri pakupindulitsa kwa ore yamkuwa kuti mupititse patsogolo.

Pomaliza, sodium hydrosuul imagwiritsidwa ntchito mu sulfite potolo utoto ndi kupanga ulusi wopangidwa ndi anthu, kuwonetsa kusinthasintha kwake komanso kufunikira kwake pakupanga kwamakono. Ndi mawonekedwe ake apamwamba komanso osiyanasiyana amagwiritsa ntchito, 70% sodium hydrosulnol amakhalabe ndi mankhwala osiyanasiyana a mafakitale osiyanasiyana, makamaka ku China, komwe kumapangidwa ndikusinthidwa kuti zikwaniritse zosowa zenizeni.
