I-Sodium Hydrosulfite 90%, Ilungele Ukuthunyelwa~

Izicelo:
1. Ukusetshenziswa kwe-sodium hydrosulfite kubanzi kakhulu, ikakhulukazi kuhlanganisa ukunciphisa ukudaya, ukunciphisa ukuhlanzwa, ukuphrinta nokukhishwa kombala embonini yendwangu, kanye nokuxubha usilika, uboya, inayiloni nezinye izindwangu. Njengoba i-sodium hydrosulfite ingenazo izinsimbi ezinzima, umbala wendwangu e-bleached ukhanya kakhulu futhi akulula ukufiphala.

2. I-sodium hydrosulfite ingase isetshenziselwe ukuhlanza ukudla, njenge-gelatin, i-sucrose, izithelo ze-candied, njll, kanye nensipho, isilwane (isitshalo) samafutha, u-bamboo, i-porcelain clay bleaching.

3. Emkhakheni we-organic synthesis, i-sodium hydrosulfite isetshenziswa njenge-ejenti yokunciphisa noma i-ejenti ye-bleaching ekukhiqizeni odayi nemithi, ikakhulukazi njenge-bleaching agent yokwenza i-wood pulp papermaking.

4. I-sodium hydrosulfite inganciphisa ama-ion amaningi ensimbi esindayo afana ne-Pb2+, i-Bi3+, njll. kuya ezinsimbi ekuhlanzeni kwamanzi nasekulawuleni ukungcola, futhi ingasetshenziswa ukugcina ukudla nezithelo.

Ingozi
Okuvutha umlilo:I-sodium dithionite iyinto yezinga lokuqala evutha umlilo uma imanzi ngokwezindinganiso zikazwelonke. Izosabela ngobudlova lapho ihlangana namanzi, ikhiqize amagesi avuthayo njenge-hydrogen sulfide ne-sulfur dioxide, futhi ikhiphe inani elikhulu lokushisa. I-equation yokusabela ithi: 2Na2S2O4+2H2O+O2=4NaHSO3, futhi imikhiqizo isabela futhi ukuze ikhiqize i-hydrogen sulfide ne-sulphur dioxide. I-sodium dithionite inesimo se-valence esimaphakathi sesulfure, futhi izakhiwo zayo zamakhemikhali azinzile. Ibonisa izakhiwo ezinciphisa amandla. Uma ihlangana nama-acid oxidizing aqinile, njenge-sulfuric acid, i-perchloric acid, i-nitric acid, i-phosphoric acid namanye ama-acids aqinile, lezi zimbili zizobhekana nokusabela kwe-redox, futhi ukusabela kunobudlova, kukhulula inani elikhulu lokushisa nezinto ezinobuthi. I-equation yayo yokusabela ithi: 2Na2S2O4+4HCl=2H2S2O4+4NaCl

Ukushiswa okuzenzakalelayo:I-sodium dithionite inephuzu elizenzakalelayo lokuvutha elingu-250 ℃. Ngenxa yephoyinti layo eliphansi lokuthungela, iwukuqina okuvutha okusezingeni lokuqala (indawo yokuthungela ngokuvamile ingaphansi kuka-300 ℃, futhi indawo ekhanyayo yephuzu elincibilikayo eliphansi ingaphansi kuka-100℃). Kulula kakhulu ukuvutha lapho kuvezwe ukushisa, umlilo, ukungqubuzana kanye nomthelela. Isivinini sokuvutha siyashesha futhi ingozi yomlilo iphezulu. Igesi ye-hydrogen sulfide ekhiqizwa phakathi nenqubo yokusha ingase ibangele indawo enkulu evuthayo, ikhulise ingozi yayo yomlilo.

Ukuqhuma:I-sodium dithionite iyimpuphu ephuzi ekhanyayo. Into eyimpuphu kulula ukwenza ingxube eqhumayo emoyeni. Ukuqhuma kothuli kwenzeka lapho uhlangana nomthombo womlilo. Ingxube ye-sodium dithionite kanye nama-oxidants amaningi, njenge-chlorate, i-nitrate, i-perhlorate, noma ama-permanganate, iyaqhuma. Ngisho nalapho kukhona amanzi, iqhuma ngemva kokungqubuzana okuncane noma umthelela, ikakhulukazi ngemva kokubola okushisayo, igesi evuthayo ekhiqizwa ngemva kokuba ukusabela kufinyelele umkhawulo wokuqhuma, khona-ke ingozi yokuqhuma kwayo inkulu.
