Sodium Hydrosulfide, sida caadiga ah loo yaqaanNAHS(UN 2949), waa dhismo kala duwan oo leh codsiyo kala duwan oo warshado ah. Waxaa lagu heli karaa kala duwanaansho kala duwan, sida 10/20/30ppm, Sodium Hydrosulfide waxaa inta badan loo isticmaalaa warshadaha dharka, waraaqaha iyo macdanta, iyada oo door muhiim ah ka ciyaaraysa hababka sida midabaynta, bleaching iyo soo saarista macdanta.

Mid ka mid ah isticmaalka ugu muhiimsan ee sodium hydrosulfide waa soo saarista sodium sulfide, gaar ahaan soo saarista saxarka iyo waraaqaha. Waxay u shaqeysaa sida wakiilka yareynta, caawinta burburinta lignin ee qoryaha, taas oo lagama maarmaan u ah soo saarista warqad tayo sare leh. Intaa waxaa dheer, warshadaha dharka, sodium hydrosulfide waxaa loo isticmaalaa sifooyinkeeda bleaching, si wax ku ool ah uga saara midabada aan loo baahnayn ee dharka.

Marka la eego kaydinta, sodium hydrosulfide waa in si taxadar leh loo maareeyaa dabeecadeeda falcelinta awgeed. Waa in lagu kaydiyaa meel qabow oo qalalan, kana fog maaddooyinka aan ku habboonayn sida asiidhka iyo oksidayaasha. Weelasha waa in la xiraa si looga hortago nuugista qoyaanka, maadaama sodium hydrosulfide ay kula falgasho biyo si ay u sii deyso sunta sunta ah ee hydrogen sulfide, taas oo keeneysa khatar caafimaad.

Aad bay muhiim u tahay qof kasta oo la shaqeeya sodium hydrosulfide hydrate ama sodium sulfide nonahydrate inuu raaco borotokoolka badbaadada, oo ay ku jiraan xidhashada qalabka ilaalinta shakhsi ahaaneed ee habboon (PPE), sida galoofyada iyo muraayadaha indhaha. Tababarka habraaca qalliinka iyo xaaladaha degdegga ah ee saxda ah sidoo kale waa lama huraan si loo xaqiijiyo goob shaqo oo ammaan ah.

Marka la soo koobo, sodium hydrosulfide waa kiimiko muhiim ah oo leh adeegsiyo kala duwan, laakiin waxay u baahan tahay in si taxadar leh loo maareeyo iyo kaydinta si loo yareeyo khatarta. Fahamka isticmaalkeeda iyo tallaabooyinka badbaadada ayaa lama huraan u ah qof kasta oo ka shaqeeya xaruntan goob warshadeed.
