Tlawmternak thilri (Rongalite)
Chemical min: Sodium hydrosulfite
Oxidizing agents he tahchunh ahcun, Rongalite nih thilpuan a hrawh tlawm deuh. Fiber phunphun in sermi thilpuan ah fahnak pe loin hman khawh a si, cucaah “Rongalite” (Tuluk holh in “a himmi buh” tinak a si) tiah min an sak. sodium hydrosulfite cu a senmi thetse bantuk asiloah a senmi a senmi chemical thilri a si i a lum khawhnak 300°C (a rawhnak) le a kanghnak lumnak cu 250°C a si. Ethanol ah a cawh kho lo nain sodium hydroxide cawhmi ah a cawh. Ti he aa tongh tikah, fakpi in a lehrulh i a kang.
Kan sodium hydrosulfite tthatnak zohfelnak cu a fek tuk, batch pakhat cio nih sehzung ah mah tein zohfelnak le thiamsang SGS zohfelnak an tuah, cu nih cun a tthatnak nih caan hneksaknak a tei khawh lai ti kha a hngalhter. A man tlawm deuhmi man hmuh awkah hika hi hmet.
