Yiziphi izakhiwo kanye nokusetshenziswa okuyinhloko kwe-rongalite?

Isikhathi: 2022-03-18 Ukushaya: 28

Igama: I-sodium formaldehyde sulfoxylate;Izigaxa zeRongalite C;I-Rongalite dihydrate;

I-sodium bisulfoxylate formaldehyde; i-sodium hydroxymethane sulfinate

Ifomula yemolekyuli:NaHSO2-CH2O-2H2O

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

Izakhiwo: Eyaziwa nangokuthi i-sodium formaldehyde bisulfate (rongalite).

I-Rongalite powder translucent white rhombohedral crystals noma izingcezu ezincane.

Ukuminyana okubonakalayo 1.80-1.85g/cm3. indawo encibilikayo engu-64℃ (encibilike emanzini acwebile). Ibola ngaphezu kuka-120°C.

Incibilika ngokukhululekile emanzini, inyibilika kancane otshwaleni.

Usawoti ongenamanzi uzinzile. Nokho, ibola kancane kancane emoyeni onomswakama. Inciphisa kakhulu emazingeni okushisa aphezulu.

Indlela yokukhiqiza enezinyathelo ezintathu zendabuko ye-rongalite powder iqukethe i-zinc powder namanzi ukwenza i-slurry,

dlulela ku-sulphur dioxide ukuze uphendule ukukhiqiza ngisho ne-zinc dithionite, bese wengeza ukwengeza kwe-formaldehyde,

i-zinc powder ukunciphisa bese isabela nge-sodium hydroxide ukuze ikhiqize.

Indlela entsha yokukhiqiza enesinyathelo esisodwa isebenzisa i-sodium metabisulphite njengento eluhlaza

futhi igcwaliswa ngesinyathelo esisodwa ngokunciphisa i-zinc powder kanye nokwengezwa kwe-formaldehyde.

Isetshenziswa njenge-ejenti yokudweba kanye ne-ejenti yokunciphisa ukuphrinta nokudaya,

ukwakhiwa kwerabha, ukukhiqizwa ushukela,

ukukhiqizwa kodayi be-indigo nokunciphisa odayi.

I-sodium formaldehyde sulfoxylate ethengiswa yi-Rongda Chemical ikhiqizwa kusetshenziswa inqubo entsha.

Ngezinzuzo ezilandelayo:

okuqukethwe okuphansi kwensimbi enzima

nikeza isevisi engcono kakhulu yangemva kokuthengisa

idumela eliphezulu emkhakheni wamakhemikhali

Xhumana nathi

Sijoyine futhi ube owokuqala ukwazi ngemikhiqizo yethu yakamuva kanye nokukhushulwa.
