I-sodium hydrosulfite 90%, ilungele ukuthunyelwa ~

Izicelo:
1. Ukusetyenziswa kwe-sodium hydrosulfite ibenzi kakhulu, ikakhulu kubandakanya ukuncitshiswa komgangatho, ukucuthwa kokucocwa, ukushicilela kunye nokudakumba kumzi-mveliso wendwangu, uboya, i-nylon kunye nezinye iindwangu. Kuba i-sodium hydrosulfite ayinazo izinyithi ezinzima, umbala wendwangu wendwangu ovuthiweyo ukhanyise kakhulu kwaye akukho lula ukupheliswa.

2. I-Sodium Hydrosulfite inokusetyenziselwa ukugxeka ukutya, njengeGelatin, i-Sinrose, isiqhamo sepinki, njl njl.

I-3. Kwintsimi ye-ornthesic synthesis, i-sodium hydrosulfite isetyenziswa njengearhente yokunciphisa okanye iarhente yobuqhetseba kwimveliso yedayi kunye namayeza, ngakumbi njengearhente ye-pip.

I-4. I-Sodium Hydrosulfite inokunciphisa ii-ion ezininzi zentsimbi ezifana ne-Pb2 +, BEBU.

Ingozi
Inokutsha:I-sodium difionite yindawo yokuqala enokufudukayo xa imanzi ngokwemigangatho yesizwe. Iya kuphendula ngogonyamelo xa iza kudibana namanzi, ivelisa igesi evuthayo njenge-hydrogen sulfide kunye nesalfur dioxide, kunye nokukhuphela inani elikhulu lobushushu. Indlela yokuphendula i I-sodium difionite inemozulu ephakathi yesalfure, kwaye iipropathi zayo zemichiza azizinzanga. Ibonisa iipropathi zokunciphisa ezomeleleyo. Xa idibana ne-oxiding acid, efana ne-sulfuric acid, i-perchloric acid, i-phospic acid, kwaye ezi zinto zininzi zinogonyamelo, zikhulule ubushushu obukhulu kunye nezinto ezinetyhefu. Indlela yayo yokuphendula yile: 2NA2S2S2S2 + 4HCL = 2h2s2s2s2o4 + 4nacl

I-ractuon yokugweba:I-sodium difionite inendawo yokuhlambela ye-250 ℃. Ngenxa yenqaku layo eliphantsi eliphantsi, yindawo yokuqala enokuqina (inqaku lendawo yokufunda ngokubanzi lingezantsi kwe-300 ℃, kwaye i-flash yendawo yendawo ephantsi yenyibiliki iphantsi kwe-100 ℃). Kulula kakhulu ukutshisa xa kufikelwa bubushushu, umlilo, uxinzelelo kunye nefuthe. Isantya sokudibana siya ngokukhawuleza kwaye ingozi yomlilo iphezulu. Igesi ye-hydrogen yerhasi ye-hydrogen iveliswe ngexesha lokudibana inokubangela i-quards enkulu, ikwandisa ingozi yomlilo.

Ukuqhuma:I-sodium difionite yindawo etyheli etyheli etyheli. I-powdery into elula yokwenza umxube wokuqhushumba emoyeni. Ukuqhushumba uthuli kwenzeka xa kudibene nomthombo womlilo. Umxube we-sodium fiion kunye ne-oxidants enkulu, enjenge-clori, i-nates, i-perchlotist, okanye isigxina, iyaqhuma. Nokuba ubukho bamanzi, buyaqhuma emva kokubekwa kancinci okanye ifuthe elincinci, ngakumbi emva kokubekwa kwe-thermal, igesi enokutsha eyenziwa emva kokuba impendulo ifikelela kumda wokuqhuma, emva koko ingozi yayo yokuqhushumba inkulu.
