I-Sodium Hydrosulfite 90%, Ilungele ukuThunyelwa ~

Usetyenziso:
1. Ukusetyenziswa kwe-sodium hydrosulfite kubanzi kakhulu, ngokukodwa kubandakanywa ukudaya kokunciphisa, ukucocwa kokunciphisa, ukuprintwa kunye nokuchithwa kwemibala kwishishini le-textile, kunye nokuxutywa kwesilika, uboya, inayiloni kunye nezinye iingubo. Ekubeni i-sodium hydrosulfite ingenayo isinyithi esinzima, umbala welaphu elifakwe i-bleached ukhanya kakhulu kwaye akukho lula ukucima.

2. I-sodium hydrosulfite ingasetyenziselwa i-bleaching yokutya, njenge-gelatin, i-sucrose, iziqhamo ze-candied, njl., kunye nesepha, isilwanyana (isityalo) ioli, i-bamboo, i-porcelain clay bleaching.

3. Kwintsimi ye-organic synthesis, i-sodium hydrosulfite isetyenziswe njenge-agent yokunciphisa okanye i-ejenti ye-bleaching ekuveliseni idayi kunye namayeza, ngokukodwa njenge-bleaching agent ye-wood pulp papermaking.

4. I-sodium hydrosulfite inokunciphisa ezininzi i-ion zetsimbi enzima ezifana ne-Pb2 +, i-Bi3 +, njl njl kwisinyithi kunyango lwamanzi kunye nokulawula ukungcola, kwaye ingasetyenziselwa ukugcina ukutya kunye neziqhamo.

Ingozi
Ukutsha:I-sodium dithionite yinto yokuqala enokutsha xa imanzi ngokwemigangatho yelizwe. Iya kusabela ngobundlobongela xa idibana namanzi, ivelise iigesi ezinokutsha ezifana ne-hydrogen sulfide kunye ne-sulfur dioxide, kwaye ikhuphe ubushushu obukhulu. I-reaction equation yile: 2Na2S2O4+2H2O+O2=4NaHSO3, kwaye iimveliso zisabela ngakumbi ukuvelisa ihydrogen sulfide kunye nesulfure dioxide. I-sodium dithionite inesimo esiphakathi se-valence yesulfure, kwaye iimpawu zayo zemichiza azinzanga. Ibonisa iimpawu zokunciphisa ezinamandla. Xa idibana nama-acids e-oxidizing enamandla, njenge-asidi ye-sulfuric, i-perchloric acid, i-nitric acid, i-phosphoric acid kunye nezinye i-acids ezinamandla, ezi zimbini ziya kusabela kwi-redox, kwaye ukusabela kunobundlobongela, ukukhulula ubuninzi bokushisa kunye nezinto ezinobuthi. I-reaction equation yile: 2Na2S2O4+4HCl=2H2S2O4+4NaCl

Ukutshisa okuzenzekelayo:I-sodium dithionite inendawo yokutshisa ezenzekelayo engama-250 ℃. Ngenxa yendawo ephantsi yokutshisa, iludidi lokuqala oluqinileyo olunokutsha (indawo yokutshisa ngokubanzi ingaphantsi kwe-300 ℃, kwaye i-flash point yendawo yokunyibilika ephantsi ingaphantsi kwe-100℃). Kulula kakhulu ukutshisa xa ibonakaliswe kubushushu, umlilo, ukukhuhla kunye neempembelelo. Isantya sokutsha sikhawuleza kwaye ingozi yomlilo iphezulu. Irhasi ye-hydrogen sulfide eveliswa ngexesha lenkqubo yokutsha inokubangela ukuba indawo enkulu yokutsha inyuse ingozi yomlilo.

Ugqabhuko:I-sodium dithionite yinto enomgubo omthubi okhanyayo. Into engumgubo kulula ukwenza umxube oqhumayo emoyeni. Ukudubula kothuli kwenzeka xa udibana nomthombo womlilo. Umxube we-sodium dithionite kunye nee-oxidants ezininzi, ezifana neklorati, i-nitrate, i-perhlorate, okanye i-permanganate, iyaqhuma. Nangona kubukho bamanzi, iqhuma emva kokungqubuzana okuncinci okanye impembelelo, ngakumbi emva kokubola kwe-thermal, igesi evuthayo eyenziwa emva kokuba impendulo ifikelele kumda wokuqhuma, ngoko ingozi yayo yokuqhuma inkulu.
