Umenzi Ixabiso Elihle Sodium metabisulfite CAS:7681-57-4

Umenzi Ixabiso Elihle I-Sodium metabisulfite CAS: 7681-57-4 Umfanekiso Obonakalayo

inkcazo emfutshane:

I-Sodium metabisulfite: (udidi lwemizi-mveliso) I-Sodium metabisulfite (ifomula yekhemikhali: Na2S2O5) ibonakala njengekristale emhlophe okanye i-powder solid enevumba elincinci lesalfure. Inetyhefu xa iphefumla kwaye inokucaphukisa kakhulu ulusu kunye nezicubu. Ingabola ukuze ikhuphe umsi we-oxide onetyhefu wesalfure kunye ne-sodium xa kushushu kakhulu. Ingaxutywa namanzi ukwenza i-asidi ebolayo. Isetyenziswa ngokubanzi njengesibulali-ntsholongwane, i-antioxidant, kunye ne-preservative agent kunye ne-reagent yelabhoratri. Njengohlobo lwesongezelelo sokutya, ingasetyenziswa njengesigcini kunye ne-antioxidant ekutyeni. Ingasetyenziselwa nokwenza iwayini kunye nebhiya. Ngaphezu koko, ingasetyenziselwa ukucoca izixhobo zebhiya yasekhaya kunye newayini njenge-arhente yokucoca. Ikwanazo nezinye iintlobo ezahlukeneyo zezicelo, umz. isetyenziswa kwifoto, njengezinto ezincedisayo kwiipilisi ezithile, ukunyanga amanzi, njengomthombo we-SO2 kwiwayini, njenge-bactericide kunye ne-reagent yokumhlopheza kunye ne-arhente yokunciphisa. Ingenziwa ngokuphuma kwe-sodium bisulfite ezaliswe yi-sulfur dioxide. Kufuneka kulumkiswe ukuba i-sodium metabisulfite inemiphumo ethile ebukhali kwinkqubo yokuphefumla, amehlo kunye nolusu. Kwimeko embi kakhulu, inokubangela ubunzima bokuphefumla kunye nomonakalo wemiphunga okhokelela ekufeni. Ke ngoko, amanyathelo okukhusela asebenzayo kunye nengqalelo kufuneka ithathwe ngexesha lotyando.

Ukusetyenziswa kweSodium metabisulfite

I-Sodium metabisulfite I-Sodium Metabisulfite, yenza i-sodium metabisulfite ngokuphendula i-sulfur dioxide ne-sodium carbonate (i-soda ash), icoca kwaye yomise ukuze yenze iikristale okanye umgubo.
I-Na2CO3 + 2SO2→Na2S2O5 + CO2
I-Sodium metabisulfite (SMBS, i-Sodium disulfite) yityuwa yesodium emhlophe, eneengqukuva eqinileyo. Ikhompawundi engaphiliyo eyenziwe yisodium, isalfure, kunye neoksijini, kwaye isetyenziswa kumashishini amaninzi:
1.kwishishini le-pulp nephepha, kwishishini leefoto nakwezinye iindawo ezahlukeneyo njenge-bleach okanye i-dechlorinator.
2. I-sodium metabisulfite yodidi lokutya ingasetyenziswa njengesigcini sokutya. Ikwafakwa rhoqo kwiimveliso ezahlukeneyo zokutya kunye neewayini njengesigcini sokutya.
3. I-sodium metabisulfite ingasetyenziswa nakwimveliso yezinye iikhemikhali, Isetyenziswa ekuveliseni izinto zokucoca, iisepha, kunye neesepha.
4. Ikwasebenza njengesithinteli sokugqwala kwishishini leoyile negesi, njengearhente yokumhlopheza kwimveliso yekhrimu yekhokhonathi, njengomthombo wesulfur dioxide nasekutshatyalalisweni kwe-cyanide kwiinkqubo zokuthengisa i-cyanidation yegolide.
5. Ishishini lemigodi yegolide: Lisetyenziswa ekukhupheni igolide kwi-auric acid kunye nasekucoceni amanzi amdaka ukususa i-hexavaent chromium njenge-trivalent chromium ngokuyisusa emva kokunciphisa.
6. I-Preservative kwizisombululo zabaphuhlisi beefoto, isetyenziswa ekufoteni.
7. Ukususa ioksijini: idlala njengomthuthi weoksijini ukuze isuse ioksijini enyibilikisiweyo emanzini amdaka nakwimibhobho.
8. I-sodium metabisulfite ingasetyenziswa njengesiqalisi ngexesha le-cross-linking polymerization ye-polybutadiene kwi-cores ye-vesicle membranes.
9. Ingongezwa njenge-antioxidant ngexesha lokulungiselela izisombululo ze-6-hydroxydopamine kwizifundo ezahlukeneyo.
10. Ukususwa kwechlorine kwizityalo zonyango lwamanzi amdaka kamasipala, ipulp kunye nephepha, umbane, kunye nemizi-mveliso yokucoca amanzi elaphu.
