Ulungelelwaniso lokuzinza
I-1.I-Soluble emanzini, isisombululo esinamanzi si-alkaline.Inyibilika kancinane etywaleni.Ayinyibiliki kwiklorine engamanzi kunye ne-ammonia.Njenge-ejenti yokunciphisa eyomeleleyo, isabela kunye ne-sulfur dioxide ukuvelisa i-sodium bisulfite, kwaye isabela nge-asidi eyomeleleyo ukuvelisa ityuwa ehambelanayo kunye nokukhulula i-sulfur dioxide.
I-2.Njenge-agent yokunciphisa eqinile, kulula i-oxidize phantsi kwesenzo somoya omanzi kunye nokukhanya kwelanga, kodwa izinzile ngakumbi kune-sodium sulfite heptahydrate.Ukubola kwenzeka xa kushushu.
Ukulungiselela
I-sodium sulfite inokulungiswa ngokuzisa i-sulfur dioxide kwisisombululo se-sodium hydroxide, kwaye xa i-sulfur dioxide igqithise, i-sodium bisulfite yenziwa.Okanye ukwazisa igesi yesulfure dioxide kwisisombululo sesodium carbonate, ukongeza isisombululo se-sodium carbonate emva kokuhluthwa, ukudibanisa ukufumana i-crystals ye-heptahydrate, kunye nokufudumeza ukukhupha amanzi ukuze ufumane i-anhydrous sodium sulfite.
Usebenzisa
I-1.Anhydrous sodium sulfite ingasetyenziswa njenge-fiber stabilizer eyenziwe ngumntu, i-agent ye-bleaching agent, umthuthukisi wezithombe, idayi kunye ne-bleaching deoxidizer, i-perfume kunye ne-agent yokunciphisa idayi, i-papermaking lignin remover, njl.;
I-2.Inokusetyenziswa njenge-deoxidizer kunye ne-agent ye-bleaching kwishishini lokuprinta kunye nokudaya, kwaye ingasetyenziselwa ukupheka kweempahla ezahlukeneyo zekotoni, ezinokuthintela i-oxidation yendawo ye-cotton fibers ekuchaphazela amandla efayibha kunye nokuphucula ubumhlophe beemveliso eziphekiweyo.
I-3.Ingasetyenziselwa ukwenza i-cellulose sulfite, i-sodium thiosulfate, iikhemikhali zezinto eziphilayo, i-bleached fabrics, njl.
I-4.Isetyenziselwa i-microanalysis kunye nokuzimisela kwe-tellurium kunye ne-niobium, ukulungiswa kwezisombululo zomphuhlisi, ukunciphisa i-agent kunye nomphuhlisi kwimboni ye-photosensitive.
I-5.Imboni ye-Organic isetyenziselwa i-agent yokunciphisa ukuveliswa kwe-m-phenylenediamine, i-2,5-dichloropyrazolone, i-anthraquinone -1-sulfonic acid, i-1-aminoanthraquinone kunye ne-aminosalicylate ye-sodium, enokuthintela i-oxidation yeemveliso ezigqityiweyo kwi-reaction. inkqubo.
6.Isetyenziswe njenge-ejenti yokunciphisa kwimveliso yemifuno ephelelwe ngamanzi.
7.Ishishini lePhepha lisetyenziswa njenge-lignin remover.
8.Ushishino lwamalaphu lusetyenziswa njengesizinzisi kwiintsinga ezenziwe ngabantu.
I-9.Isetyenziswa njenge-reagent eqhelekileyo yokuhlalutya kunye ne-photosensitive resistant material, ishishini lombane lisetyenziselwa ukuvelisa ukuchasana kwe-photosensitive.
10.Ishishini lokucocwa kwamanzi lisetyenziselwa ukunyanga amanzi amdaka e-electroplating kunye namanzi okusela.
