Ukusetyenziswa kunye nophuhliso lwenkqubo ye-sodium formaldehyde sulfoxylate

Ixesha: 2021-07-09 Indawo: 237

I-Sodium sulfoxylate formaldehyde (NaHSO2 · CH2O · 2H2O),

Ikwabizwa ngokuba yi assodium formaldehyde sulfoxylate.

Igama lemveliso:Rongalite C.

Yibhloko emhlophe ekhanyayo enendawo yokunyibilika engama-64 ℃. Inokunciphisa okunamandla kumaqondo obushushu aphezulu kwaye inokuphela amalaphu adayiweyo.

Ke ngoko, isetyenziswa kakhulu njengearhente yokukhupha kwishishini lokuprinta kunye nokudaya, njenge-ejenti yokucoca kwi-rubber synthesis kunye neshishini leswekile.

Ngophuhliso kunye nokusetyenziswa kweemveliso, kwiminyaka yakutshanje, sele isetyenziswe kwishishini lesepha kunye nonyango lwezonyango njenge-antidote ye-Hg, i-Bi, i-Ba.

Ukuveliswa kwe-rongalite ngokuqhelekileyo kusebenzisa indlela yemveli enemigangatho emithathu, indlela yezinc powder-sulphur dioxide-formaldehyde.

Oko kukuthi, i-sulphur dioxide, i-zinc powder, kunye ne-formaldehyde zisetyenziswa njengezinto eziluhlaza, kunye ne-sulfure dioxide kunye ne-zinc powder isabela kwi-zinc dithionite (ZnS2O4), kwaye emva koko i-formaldehyde yokongeza, ukunciphisa i-zinc powder kunye ne-sodium hydroxide metathesis reaction ukwenza imveliso.

Ukuveliswa kwe-domeryrongalite kwakhona kusebenzisa ubugcisa besintu obukhankanywe ngasentla. Iimveliso zinikezelwa ikakhulu kwimarike yasekhaya, kwaye ezinye zithunyelwa kuMzantsi-mpuma Asia.

Oko sikuzisayo inkqubo entsha , oko kukuthi, inkqubo yokufumana imveliso kwi-sodium metabisulfite njengento eluhlaza ngokunciphisa i-zinc powder kunye nokongezwa kwe-formaldehyde kwinqanaba elinye.

Izinto eziluhlaza ziyancipha kwaye zongezwa kwi-kettle efanayo, kwaye zonke ii-reactants ziguqulwa zibe yimveliso, kwaye akukho nkunkuma.

Ukongeza kwiimveliso eziphambili, iphinda ivelise i-chemically pure zinc oxide (99.5%) iimveliso.

Inkqubo ineempawu zenkqubo emfutshane, iimeko zobugcisa ezizinzile, utyalo-mali oluphantsi lwezixhobo kunye nokusebenza okulula.

Kwinqaku elilandelayo, ndiza kwabelana ngenkqubo yemveliso enxulumene nesodium formaldehyde sulfoxylate.
