Ukuhambisana nokuzinza
1.Incibilika emanzini, isixazululo esinamanzi sine-alkaline.Incibilika kancane otshwaleni.Ayincibiliki ku-liquid chlorine ne-ammonia.Njenge-ejenti yokunciphisa eqinile, ihlangana ne-sulphur dioxide ukuze ikhiqize i-sodium bisulfite, futhi isabela nge-asidi eqinile ukuze ikhiqize usawoti ohambisanayo futhi ikhulule i-sulphur dioxide.
I-2.Njenge-ejenti yokunciphisa eqinile, kulula ukwenza i-oxidize ngaphansi kwesenzo somoya omswakama nokukhanya kwelanga, kodwa izinzile kune-sodium sulfite heptahydrate.Ukubola kwenzeka lapho kushisa.
Ukulungiselela
I-sodium sulfite ingalungiswa ngokwethula i-sulfur dioxide kusisombululo se-sodium hydroxide, futhi lapho i-sulfur dioxide ingaphezu kwamandla, i-sodium bisulfite iyakhiqizwa.Noma ukwethula igesi ye-sulphur dioxide esixazululweni se-sodium carbonate, ukwengeza isisombululo se-sodium carbonate ngemva kokugcwala, ukucwebezela ukuze kutholwe amakristalu e-heptahydrate, nokushisisa ukuze kuqede amanzi ukuze kutholwe i-anhydrous sodium sulfite.
Isebenzisa
I-1.Anhydrous sodium sulfite ingasetshenziswa njenge-fiber stabilizer eyenziwe ngumuntu, i-ejenti yokuxubha indwangu, umthuthukisi wezithombe, udayi kanye ne-bleaching deoxidizer, i-perfume ne-ejenti yokunciphisa udayi, i-papermaking lignin remover, njll.;
I-2.Ingasetshenziswa njenge-deoxidizer kanye ne-bleaching agent embonini yokunyathelisa nokudaya, futhi ingasetshenziswa ekuphekeni izindwangu ezihlukahlukene zikakotini, ezingavimbela i-oxidation yendawo yezintambo zikakotini ekuthinteni amandla e-fiber futhi ithuthukise ubumhlophe bemikhiqizo ephekiwe.
I-3.Ingase futhi isetshenziselwe ukwenza i-cellulose sulfite, i-sodium thiosulfate, amakhemikhali e-organic, izindwangu ezi-bleached, njll, futhi iphinde isetshenziswe njenge-ejenti yokunciphisa, i-preservative, i-agent dechlorination, njll.
I-4.Isetshenziselwa ukuhlaziya okuncane nokunqunywa kwe-tellurium ne-niobium, ukulungiswa kwezixazululo zonjiniyela, i-ejenti yokunciphisa kanye nomthuthukisi embonini ye-photosensitive.
I-5.Imboni ye-Organic isetshenziswa njenge-ejenti yokunciphisa ekukhiqizeni i-m-phenylenediamine, i-2,5-dichloropyrazolone, i-anthraquinone -1-sulfonic acid, i-1-aminoanthraquinone ne-sodium aminosalicylate, engavimbela i-oxidation yemikhiqizo eqediwe ekuphenduleni. inqubo.
6.Isetshenziswa njenge-ejenti yokunciphisa ekukhiqizeni imifino ephelelwe amanzi.
7.Imboni yamaphepha isetshenziswa njengesikhiphi se-lignin.
8.Imboni yezindwangu isetshenziswa njengesiqinisi imicu eyenziwe ngumuntu.
I-9.Isetshenziswa njenge-reagent evamile yokuhlaziya kanye nezinto zokumelana ne-photosensitive, imboni ye-elekthronikhi isetshenziselwa ukwenza ukumelana ne-photosensitive.
10.Imboni yokuhlanza amanzi isetshenziselwa ukwelapha amanzi angcolile e-electroplating namanzi okuphuza.
