I-Sodium Hydrosulfite 90%, Ilungele Ukuthunyelwa~

Izicelo:
1. Ukusetshenziswa kwe-sodium hydrosulfite kubanzi kakhulu, ikakhulukazi okuhlanganisa ukudaya kokunciphisa, ukuhlanza kokunciphisa, ukuphrinta kanye nokususa umbala embonini yezindwangu, kanye nokumhlopheza isilika, uboya, inayiloni nezinye izindwangu. Njengoba i-sodium hydrosulfite ingenazo izinsimbi ezisindayo, umbala wendwangu ephuziwe ukhanya kakhulu futhi akulula ukuwufiphaza.

2. I-sodium hydrosulfite ingasetshenziswa futhi ekukhanyeni kokudla, njenge-gelatin, i-sucrose, izithelo ezifakwe amaswidi, njll., kanye nensipho, uwoyela wezilwane (wezitshalo), uqalo, ukumhlopheza ngobumba lwe-porcelain.

3. Emkhakheni wokwenziwa kwezinto eziphilayo, i-sodium hydrosulfite isetshenziswa njenge-ejenti yokunciphisa noma i-ejenti yokumhlopheza ekukhiqizweni kodayi nemithi, ikakhulukazi njenge-ejenti yokumhlopheza yokwenza iphepha lezinkuni.

4. I-sodium hydrosulfite inganciphisa ama-ion amaningi ensimbi esindayo njenge-Pb2+, i-Bi3+, njll. abe yizinsimbi ekuphathweni kwamanzi nasekulawulweni kokungcola, futhi ingasetshenziswa futhi ukulondoloza ukudla nezithelo.

Ingozi
Okungavutha:I-Sodium dithionite iyinto evuthayo esezingeni lokuqala uma imanzi ngokwezindinganiso zikazwelonke. Izosabela ngamandla uma ihlangana namanzi, ikhiqize amagesi avuthayo njenge-hydrogen sulfide kanye ne-sulfur dioxide, futhi ikhiphe ukushisa okukhulu. I-reaction equation ithi: 2Na2S2O4+2H2O+O2=4NaHSO3, futhi imikhiqizo isabela kakhulu ekukhiqizeni i-hydrogen sulfide kanye ne-sulfur dioxide. I-Sodium dithionite inesimo se-valence esiphakathi se-sulfur, futhi izakhiwo zayo zamakhemikhali azizinzile. Ibonisa izakhiwo ezinciphisa kakhulu. Uma ihlangana nama-oxidizing acid anamandla, njenge-sulfuric acid, i-perchloric acid, i-nitric acid, i-phosphoric acid kanye namanye ama-acid aqinile, lokhu kokubili kuzobhekana nokusabela kwe-redox, futhi ukusabela kuba nobudlova, kukhipha ukushisa okukhulu nezinto ezinobuthi. I-reaction equation yayo ithi: 2Na2S2O4+4HCl=2H2S2O4+4NaCl

Ukusha okuzenzakalelayo:I-Sodium dithionite inephuzu lokusha elizenzakalelayo elingu-250℃. Ngenxa yephuzu layo eliphansi lokusha, iyisiqina esivuthayo sekilasi lokuqala (iphuzu lokusha ngokuvamile lingaphansi kuka-300℃, kanti iphuzu lokusha lephuzu lokuncibilika eliphansi lingaphansi kuka-100℃). Kulula kakhulu ukusha uma ibhekene nokushisa, umlilo, ukungqubuzana kanye nokushayisana. Ijubane lokusha liyashesha futhi ingozi yomlilo iphezulu. Igesi ye-hydrogen sulfide ekhiqizwa ngesikhathi senqubo yokusha nayo ingabangela indawo enkulu yokusha, okwandisa ingozi yayo yomlilo.

Ukuqhuma:I-Sodium dithionite iyinto ephuzi kancane efana nempuphu. Into ewumpuphu kulula ukuyenza ingxube eqhumayo emoyeni. Ukuqhuma kothuli kwenzeka lapho kuhlangatshezwana nomthombo womlilo. Ingxube ye-sodium dithionite kanye nama-oxidant amaningi, njenge-chlorate, i-nitrate, i-perchlorate, noma i-permanganate, iyaqhuma. Ngisho noma kukhona amanzi, iyaqhuma ngemva kokungqubuzana okuncane noma ukushaya, ikakhulukazi ngemva kokubola kokushisa, igesi evuthayo ekhiqizwa ngemva kokuba ukusabela kufinyelele umkhawulo wokuqhuma, khona-ke ingozi yayo yokuqhuma inkulu.
