Umkhiqizi Intengo Enhle I-Sodium metabisulfite CAS:7681-57-4

incazelo emfushane:

I-sodium metabisulfite : (ibanga lezimboni) I-sodium metabisulfite (ifomula yamakhemikhali: Na2S2O5) ibonakala njengekristalu emhlophe noma impushana eqinile enephunga elincane lesulfure.Inobuthi lapho uhogela futhi ingacasula kakhulu isikhumba nezicubu.Ingaboliswa ukuze ikhiphe intuthu ye-toxic oxide yesibabule nesodium lapho izinga lokushisa liphezulu.Ingaxutshwa namanzi ukwenza i-asidi edlayo.Ngokuvamile isetshenziswa njengesibulala-magciwane, i-antioxidant, ne-preservative agent kanye ne-reagent yaselabhorethri.Njengesengezo sokudla, singasetshenziswa njengesilondolozi kanye ne-antioxidant ekudleni.Ingasetshenziswa futhi ekwenzeni iwayini nobhiya.Ngaphezu kwalokho, ingasetshenziswa ukuhlanza imishini ye-homebrew kanye nokwenza iwayini njenge-ejenti yokuhlanza.Iphinde ibe nezinhlobo ezehlukene zezinye izinhlelo zokusebenza, isb. ukusetshenziswa ekuthwebuleni izithombe, njengezinto ezisizayo kwamanye amaphilisi, ukwelapha amanzi, njengomthombo we-SO2 ewayinini, njengesibulala-magciwane kanye ne-reagent yokushibilika kanye ne-ejenti yokunciphisa.Ingenziwa ngokusebenzisa ukuhwamuka kwe-sodium bisulfite egcwele i-sulphur dioxide.Kufanele kuxwayiswe ukuthi i-sodium metabisulfite inemiphumela ethile ebukhali ohlelweni lokuphefumula, amehlo nesikhumba.Ezimweni ezimbi kakhulu, kungabangela ubunzima bokuphefumula kanye nokulimala kwamaphaphu okuholela ekufeni ekugcineni.Ngakho-ke, izinyathelo zokuzivikela eziphumelelayo kanye nokunakwa kufanele kuthathwe ngesikhathi sokusebenza.

Izicelo ze-Sodium metabisulfite

I-sodium metabisulfite I-Sodium Metabisulphite, ikhiqiza i-sodium metabisulfite ngokusabela i-sulfur dioxide ne-sodium carbonate (umlotha we-soda), ukuhlanza nokomisa ukwenza amakristalu noma impushana.
I-Na2CO3 + 2SO2→Na2S2O5 + CO2
I-sodium metabisulfite (i-SMBS, i-Sodium disulfite) iwusawoti oqinile we-sodium omhlophe, oyimbudumbudu.inhlanganisela ye-inorganic eyakhiwe nge-sodium, isulfure, nomoya-mpilo, futhi isetshenziswa ezimbonini eziningi:
1.embonini ye-pulp nephepha, embonini yezithombe nakwezinye izimboni ezihlukahlukene njenge-bleach noma i-dechlorinator.
I-2.Ibanga Lokudla I-sodium metabisulfite ingasetshenziswa njengesilondolozi sokudla.Ibuye yengezwe emikhiqizweni yokudla ehlukahlukene kanye namawayini njengesivikelo.
3.I-Sodium metabisulfite ingasetshenziswa futhi ekwenzeni amanye amakhemikhali, Asetshenziswa ekukhiqizeni izinto zokuhlanza, okokuhlanza, nezinsipho.
I-4.Isebenza futhi njenge-corrosion inhibitor embonini kawoyela negesi, njenge-ejenti ye-bleaching ekukhiqizeni ukhilimu kakhukhunathi, njengomthombo we-sulfur dioxide kanye nokubhujiswa kwe-cyanide ezinqubweni zegolide ze-cyanidation.
5.Imboni yezimayini zegolide: Isetshenziselwa ukuna kwegolide elisuka ku-auric acid kanye nasekuhlanzeni amanzi angcolile ukuze kususwe i-chromium ene-hexavaent njenge-chromium eyi-trivalent ngemvula ngemva kokuncipha.
6.Isilondolozi kuzixazululo zonjiniyela wezithombe, sisetshenziswa ezithombeni.
7.I-oxygen scavenge: idlala njenge-oxygen scavenger ukususa umoya-mpilo oncibilikisiwe emanzini angcolile nasemapayipini.
I-8.I-metabisulfite ye-sodium ingasetshenziswa njenge-initiator ngesikhathi se-polymerization ye-cross-linking ye-polybutadiene kuma-cores we-vesicle membranes.
I-9.Ingase yengezwe njenge-antioxidant ngesikhathi sokulungiswa kwezixazululo zesitoko se-6-hydroxydopamine ezifundweni ezihlukahlukene.
10.Ukukhipha i-chlorination emanzini angcolile kamasipala, i-pulp & paper, amandla, nezindawo zokuhlanza amanzi ezindwangu.
