Umenzi wexabiso eliLungileyo I-Sodium metabisulfite CAS:7681-57-4 Umfanekiso ofakiweyo

inkcazelo emfutshane:

I-sodium metabisulfite : (i-industrial grade) I-sodium metabisulfite (ifomula yekhemikhali: Na2S2O5) ibonakala njengekristale emhlophe okanye i-powder eqinile enevumba elincinane lesulfure.Inetyhefu xa uphefumla kwaye inokucaphukisa kakhulu ulusu kunye nezicubu.Inokubola ukuze ikhuphe imisi eyityhefu yesulfure kunye nesodium kubushushu obuphezulu.Inokuxutywa namanzi ukwenza iasidi eyonakalisayo.Ngokuqhelekileyo isetyenziswa njengesibulali ntsholongwane, i-antioxidant, kunye ne-preservative agent kunye ne-reagent yaselabhoratri.Njengohlobo lwesongezo sokutya, lunokusetyenziswa njengento yokugcina kunye ne-antioxidant ekutyeni.Isenokusetyenziswa ekwenzeni iwayini kunye nebhiya.Ngapha koko, inokusetyenziselwa ukucoca izixhobo ze-homebrew kunye ne-winemaking njengearhente yokucoca.Ikwanazo neentlobo ngeentlobo zezinye izinto ezisetyenziswayo, umz. ukusetyenziswa ekufotweni, njengezincedisi kwezinye iipilisi, ukucocwa kwamanzi, njengomthombo we-SO2 ekwiwayini, njengesibulali-ntsholongwane kunye nesixhobo sokuthambisa i-bleaching kunye ne-arhente yokunciphisa.Inokwenziwa ngokuphuma komphunga kwisodium bisulfite ezaliswe yisulfure dioxide.Kufuneka ilumkiswe ukuba i-sodium metabisulfite ineziphumo ezithile ezibukhali kwinkqubo yokuphefumla, amehlo kunye nolusu.Kwimeko emandundu, kunokubangela ubunzima bokuphefumla kunye nomonakalo wemiphunga okhokelela ekufeni ekugqibeleni.Ngoko ke, amanyathelo okukhusela asebenzayo kunye nokuqwalaselwa kufuneka kuthathwe ngexesha lokusebenza.

Ukusetyenziswa kweSodium metabisulfite

I-Sodium metabisulfite I-Sodium Metabisulphite, ivelisa i-sodium metabisulfite ngokuphendula i-sulfur dioxide kunye ne-sodium carbonate (uthuthu lwesoda), ukucoca kunye nokomisa ukwenza iikristale okanye umgubo.
Na2CO3 + 2SO2→Na2S2O5 + CO2
I-sodium metabisulfite (i-SMBS, i-Sodium disulfite) yityuwa emhlophe, i-granular eqinile yesodium.Ikhompawundi ye-inorganic eyenziwe ngesodium, isulfure, kunye neoksijini, kwaye isetyenziswa kumashishini amaninzi:
1.kwishishini lepulp kunye nephepha, kwishishini lemifanekiso kunye nakwamanye amashishini ahlukeneyo njengebleach okanye i-dechlorinator.
I-2.Ukutya kwiBanga lokutya i-sodium metabisulfite ingasetyenziselwa njengento yokugcina ukutya.Ikwadityaniswe ngokuqhelekileyo kwiimveliso zokutya ezahlukeneyo kunye newayini njengesigcini.
3.I-Sodium metabisulfite isenokusetyenziswa ekwenzeni ezinye iikhemikhali, ezisetyenziselwa ukuvelisa izinto zokucoca, izicoci kunye neesepha.
I-4.Ikwasebenza njenge-corrosion inhibitor kwi-oyile kunye ne-gas industry, njenge-ejenti ye-bleaching ekuveliseni i-coconut cream, njengomthombo we-sulfure dioxide kunye nokutshatyalaliswa kwe-cyanide kwiinkqubo zegolide ze-cyanidation.
5.Ishishini lemigodi yegolide: Isetyenziswa kwimvula yegolide esuka kwi-auric acid kunye nakunyango lwamanzi asetyenzisiweyo ukususa i-chromium enehexavaent njenge-chromium ene-trivalent ngemvula emva kokuncipha.
I-6.I-Preservative kwizisombululo zomphuhlisi wezithombe, isetyenziswe kwiifoto.
7.I-Oxygen scavenge: idlala njenge-oxygen scavenger ukuphelisa i-oksijini enyibilikileyo emanzini amdaka kunye nakwimibhobho.
I-8.I-metabisulfite ye-sodium ingasetyenziselwa njenge-initiator ngexesha le-polymerization ye-cross-linking ye-polybutadiene kwiinqununu ze-vesicle membranes.
I-9.Inokongezwa njenge-antioxidant ngexesha lokulungiswa kwezisombululo zesitokhwe ze-6-hydroxydopamine kwizifundo ezahlukeneyo.
10. Ukususwa kwekhlohlo kumanzi amdaka kamasipala, ipulp & iphepha, amandla, kunye nezixhobo zokucocwa kwamanzi ezilukiweyo.
