Igoa: Sodium formaldehyde sulfoxylate; Rongalite C lumps; Rongalite dihydrate;

Sodium bisulfoxylate formaldehyde;sodium hydroxymethane sulfinate

Fuafuaga mole:NaHSO2-CH2O-2H2O

CAS No.:149-44-0/6035-47-8

Meatotino: E lauiloa foi o le sodium formaldehyde bisulfate (rongalite).

Rongalite pa'u translucent tioata rhombohedral papa'e po'o ni vaega laiti.

Fa'aaliga manino 1.80-1.85g/cm3. liusuavai 64 ℃ (fa'amuta i lona vai tioata). E pala ile 120°C.

Solu fua ile vai, solu teisi ile ava malosi.

O le masima anhydrous e sili atu ona mautu. Ae ui i lea, e faasolosolo malie ona pala i le ea susu. Malosi fa'aitiitia ile vevela maualuga.

O le auala masani e tolu-laasaga gaosiga mo le paʻu lualite e aofia ai le paʻu zinc ma le vai e fai ai se slurry,

pasi i totonu o le sulfur dioxide mo le tali atu e maua ai le zinc dithionite, ona faʻaopopo lea o le formaldehyde faaopoopo,

fa'aitiitiga o le pa'u o le zinc ona fa'afeagai lea ma le sodium hydroxide e maua ai.

Ole auala fou ole la'asaga e tasi e fa'aaogaina ai le sodium metabisulphite e fai ma mea mata

ma fa'amae'aina i le la'asaga tasi e ala i le fa'aitiitia o le pauta o le zinc ma le fa'aopoopoina o le formaldehyde.

E faʻaaogaina e fai ma sui tusi ata ma faʻaititia le sui mo le lolomiina ma le valiina,

mo le tuufaatasia o le paʻu, mo le gaosiga o suka,

mo le gaosia o lanu o le indigo ma le faʻaitiitia o vali.

Ole sodium formaldehyde sulfoxylate fa'atau atu e Rongda Chemical o lo'o gaosia ile fa'aogaina ole faiga fou.

Faatasi ai ma tulaga lelei nei:

pito i lalo ole u'amea mamafa

ofo atu auaunaga sili pe a uma ona faatau atu

ta'uleleia pito i luga i fanua kemisi

Faafesootai matou

Auai ma matou ma ia muamua e iloa e uiga i a matou oloa fou ma faʻalauiloa.
