I-Sodium Hydrosulfite 90%, Ilungele Ukuthunyelwa ~

Izicelo:
1. Ukusetyenziswa kwe-sodium hydrosulfite kubanzi kakhulu, kubandakanya ukudaya okuncitshisiweyo, ukucoca okuncitshisiweyo, ukuprinta kunye nokususa umbala kwishishini lempahla, kunye nokunyibilikisa isilika, uboya, i-nylon kunye nezinye izinto ezilahlwayo. Ekubeni i-sodium hydrosulfite ingenazo iintsimbi ezinzima, umbala welaphu elincanyathisiweyo ukhanya kakhulu kwaye akukho lula ukuwucima.

2. I-sodium hydrosulfite ingasetyenziselwa ukunyibilikisa ukutya, njenge-gelatin, i-sucrose, iziqhamo eziswiti, njl.njl., kunye nesepha, ioyile yezilwanyana (yezityalo), i-bamboo, ukunyibilikisa udongwe lwe-porcelain.

3. Kwicandelo lokwenziwa kwezinto eziphilayo, i-sodium hydrosulfite isetyenziswa njenge-arhente yokunciphisa okanye i-arhente yoku-bleach kwimveliso yeedayi namayeza, ingakumbi njenge-arhente yoku-bleach ekwenzeni iphepha le-pulp yomthi.

4. I-sodium hydrosulfite inokunciphisa ii-ion ezininzi zesinyithi esinzima ezifana ne-Pb2+, i-Bi3+, njl. zibe zisinyithi ekucoceni amanzi nasekulawuleni ungcoliseko, kwaye ingasetyenziselwa ukugcina ukutya neziqhamo.

Ingozi
Inokutsha:I-Sodium dithionite yinto etshayo yodidi lokuqala xa imanzi ngokwemigangatho yesizwe. Iya kusabela ngamandla xa idibana namanzi, ivelise iigesi ezitshayo ezifana ne-hydrogen sulfide kunye ne-sulfur dioxide, kwaye ikhuphe ubushushu obuninzi. I-reaction equation yile: 2Na2S2O4+2H2O+O2=4NaHSO3, kwaye iimveliso zisabela ngakumbi ukuvelisa i-hydrogen sulfide kunye ne-sulfur dioxide. I-Sodium dithionite inesimo se-valence esiphakathi se-sulfur, kwaye iipropati zayo zeekhemikhali azizinzanga. Ibonisa iipropati ezinciphisayo ezinamandla. Xa idibana nee-acids ezinamandla ze-oxidizing, ezifana ne-sulfuric acid, i-perchloric acid, i-nitric acid, i-phosphoric acid kunye nezinye ii-asidi ezinamandla, ezi zimbini ziya kudlula kwi-redox reaction, kwaye i-reaction idlamkile, ikhupha ubushushu obuninzi kunye nezinto ezinobuthi. I-reaction equation yayo yile: 2Na2S2O4+4HCl=2H2S2O4+4NaCl

Ukutsha okuzenzekelayo:I-Sodium dithionite ine-spontaneous combustion point ye-250℃. Ngenxa ye-ignition point yayo ephantsi, si-first-class flammable solid (i-ignition point idla ngokuba ngaphantsi kwe-300℃, kwaye i-flash point ye-melting point ephantsi ingaphantsi kwe-100℃). Kulula kakhulu ukuyitshisa xa ibekwe kubushushu, emlilweni, ekungqubaneni nasekubetheni. Isantya sokutsha siyakhawuleza kwaye ingozi yomlilo iphezulu. Igesi ye-hydrogen sulfide yegesi eveliswa ngexesha lenkqubo yokutsha inokubangela indawo enkulu yokutsha, okwandisa ingozi yayo yomlilo.

Ukuqhuma:I-Sodium dithionite yinto etyheli ekhanyayo efana nomgubo. Le nto ifana nomgubo kulula ukuyenza umxube oqhumayo emoyeni. Ukuqhuma kothuli kwenzeka xa kudibana nomthombo womlilo. Umxube we-sodium dithionite kunye nee-oxidants ezininzi, ezifana nee-chlorates, ii-nitrates, ii-perchlorates, okanye ii-permanganate, ziyaqhuma. Nokuba kukho amanzi, iyaqhuma emva kokungqubana okuncinci okanye ukungqubana, ingakumbi emva kokubola kobushushu, igesi evuthayo eveliswa emva kokuba impendulo ifikelele kumda wokuqhuma, ke ingozi yayo yokuqhuma inkulu.
