I-Sodium hydrosulfite 90%, ilungele ukuthunyelwa ~

Izicelo:
1. Ukusetshenziswa kwe-sodium hydrosulfite kubanzi kakhulu, ikakhulukazi kufaka phakathi ukudaya ukuncishiswa, ukuhlanza ukunciphisa, ukuphrinta kanye nokuhlobisisa embonini yezindwangu, kanye nokuqhuma kwesilika, uboya, i-nylon nezinye izindwangu. Njengoba i-sodium hydrosulfite ayiqukethe izinsimbi ezisindayo, umbala wendwangu ohlanganisiwe uqhakazile kakhulu futhi akulula ukunyamalala.

2. I-sodium hydrosulfite nayo ingasetshenziselwa ukugcwala kokudla, njenge-gelatin, i-sucrose, izithelo ezi-candweired, njll., Kanye nensipho, isilwane

I-3. Ensimini yokuhlanganiswa kwe-organic, i-sodium hydrosulfite isetshenziswa njenge-ejenti yokunciphisa noma i-ejenti yokuqhuma ekukhiqizweni kwamadayi nemithi, ikakhulukazi njenge-ejenti yokufafaza ngokhuni lwamaphepha olwandle.

I-4. I-Sodium hydrosulfite inganciphisa ama-ion amaningi esindayo afana ne-PB2 +, BI3 +, njll. Ezingeni lokulashwa kwamanzi nokulawulwa kokungcola, futhi nakho kungasetshenziselwa ukugcina ukudla nezithelo.

Ingozi
Kuyavutha:I-Sodium Dithionite iyinto yokuqala evuthayo lapho imanzi ngokuya ngamazinga kazwelonke. Izophendula ngobudlova uma ihlangana namanzi, ikhiqiza amagesi avuthayo njenge-hydrogen sulfide ne-sulffur dioxide kanye nokukhipha inani elikhulu lokushisa. I-equation yokuphendula yile: 2Na2S2O4 + 2h2O + O2 = 4nahso3, futhi imikhiqizo iqhubeka futhi ukuphendula ukukhiqiza i-hydrogen sulfide kanye nesibabule. I-Sodium Dithionite inesimo se-valence esiphakathi sesibabule, kanti izakhiwo zayo zamakhemikhali azizinzile. Ibonisa izakhiwo eziqinile ezinciphisa. Lapho ihlangana nama-acid anamandla anamandla, njenge-sulfuric acid, i-perchloric acid, i-nitric acid, ama-phosphoric acid namanye ama-acid anamandla, futhi ukusabela kudlama kabusha, kukhishwa inani elikhulu lokushisa nezinto ezinobuthi. Ukulingana kwalo kungukuthi: 2Na2S2O4 + 4hcl = 2h2s2o4 + 4Nacl

Ukuqina okuzenzakalelayo:I-Sodium Dithionite inendawo yokuvutha ezenzile ka-250 ℃. Ngenxa yendawo yayo yokulahla ephansi, kuyisididi esivuthayo sokuqala (indawo yokulahla ngokuvamile ingaphansi kwama-300 ℃, futhi iphuzu le-flash lephuzu eliphansi eliphansi lingaphansi kwe-100 ℃) ngaphansi kwe-100 ℃) ngaphansi kwe-100 ℃). Kulula kakhulu ukushiswa lapho kuvezwa ukushisa, umlilo, ukufutheka kanye nomthelela. Ijubane lokuvutha ngokushesha futhi ingozi yomlilo iphakeme. Igesi yegesi ye-yydrogen sulfide ekhiqizwa ngesikhathi senqubo yokuvutha nayo ingadala indawo enkulu yokuhlanganisa, yandisa ingozi yayo yomlilo.

Ukuqhuma:I-Sodium Dithionite iyinto ekhanyayo ephuzi ephuzi. Into eyi-powdery kulula ukwakha ingxube eqhumayo emoyeni. Ukuqhuma kothuli kwenzeka lapho uhlangabezana nomthombo womlilo. Ingxube ye-sodium dithonite kanye nama-oxidants amaningi, njengama-chlorates, ama-nitrate, ama-perchlorates, noma izivakashi, ziyaqhuma. Ngisho nasebukhoneni lamanzi, kuqhuma ngemuva kokuxabana okuncane noma umthelela, ikakhulukazi ngemuva kokuwohloka okushisayo, kukhiqizwe igesi evuthayo ngemuva kokuthi ukusabela kufinyelela umkhawulo wokuqhuma, khona-ke ingozi yokuqhuma inkulu.
