Chaw tsim tshuaj paus Zoo Nqe Sodium metabisulfite CAS: 7681-57-4

piav qhia luv luv:

Sodium metabisulfite : (qib kev lag luam) Sodium metabisulfite (tshuaj formula: Na2S2O5) tshwm li dawb crystalline los yog hmoov khoom nrog me ntsis sulfur tsw.Nws yog tshuaj lom thaum nqus tau thiab tuaj yeem ua rau tawv nqaij thiab cov ntaub so ntswg.Nws tuaj yeem decomposed kom tso tawm cov pa phem oxide ntawm leej faj thiab sodium thaum kub siab.Nws tuaj yeem tov nrog dej los tsim cov kua qaub corrosive.Nws feem ntau yog siv los ua tshuaj tua kab mob, tshuaj tua kab mob antioxidant, thiab tshuaj tua kab mob ntxiv rau hauv chav kuaj reagent.Raws li ib yam khoom noj khoom haus additive, nws tuaj yeem siv los ua cov khoom noj khoom haus thiab antioxidant hauv cov zaub mov.Nws tseem tuaj yeem siv rau kev ua cawv thiab npias.Ntxiv mus, nws tuaj yeem siv los ntxuav cov cuab yeej ntawm homebrew thiab winemaking ua tus neeg saib xyuas.Nws kuj muaj ntau hom kev siv lwm yam, xws li siv rau kev yees duab, ua cov khoom siv hauv qee cov ntsiav tshuaj, rau kev kho dej, ua ib qho chaw ntawm SO2 hauv cawv, ua cov kab mob thiab ua cov tshuaj dawb huv thiab txo tus neeg sawv cev.Nws tuaj yeem tsim los ntawm evaporation ntawm sodium bisulfite uas tau saturated nrog sulfur dioxide.Nws yuav tsum tau ceeb toom tias sodium metabisulfite muaj qee yam mob hnyav rau ntawm lub ntsws, qhov muag thiab tawv nqaij.Hauv qhov xwm txheej hnyav, nws tuaj yeem ua rau ua pa nyuaj thiab txawm tias pulmonary puas tsuaj uas thaum kawg ua rau tuag.Yog li ntawd, kev tiv thaiv zoo thiab kev saib xyuas yuav tsum tau ua thaum lub sijhawm ua haujlwm.

Kev siv ntawm Sodium metabisulfite

Sodium metabisulfite Sodium Metabisulphite, manufactures sodium metabisulfite los ntawm reacting sulfur dioxide nrog sodium carbonate (soda tshauv), purifying thiab ziab kom tsim muaju los yog hmoov.
Na2CO3 + 2SO2 → Na2S2O5 + CO2
Sodium metabisulfite (SMBS, Sodium disulfite) yog dawb, granular khoom sodium ntsev.ib qho inorganic compound ua los ntawm sodium, sulfur, thiab oxygen, thiab siv nyob rau hauv ntau industries:
1.nyob rau hauv kev lag luam pulp thiab ntawv, nyob rau hauv kev lag luam kev yees duab thiab nyob rau hauv ntau yam industries raws li ib tug bleach los yog dechlorinator.
2.Food Grade sodium metabisulfite tuaj yeem siv los ua zaub mov noj.Nws kuj yog feem ntau ntxiv rau ntau yam khoom noj khoom haus thiab wines raws li kev khaws cia.
3.Sodium metabisulfite kuj tseem siv tau rau hauv kev tsim khoom ntawm lwm yam tshuaj, Siv hauv kev tsim cov tshuaj ntxuav, tshuaj ntxuav tes, thiab xab npum.
4.Nws kuj ua raws li kev tiv thaiv corrosion hauv kev lag luam roj thiab roj, ua cov tshuaj pleev xim rau hauv kev tsim cov txiv maj phaub qab zib, raws li qhov chaw ntawm sulfur dioxide thiab kev puas tsuaj ntawm cyanide hauv kev lag luam kub cyanidation txheej txheem.
5.Gold mining kev lag luam: Nws yog siv los nag los ntawm kub los ntawm auric acid nrog rau hauv kev kho dej khib nyiab kom tshem tawm hexavaent chromium li trivalent chromium los ntawm nag lossis daus tom qab txo.
6.Preservative hauv kev daws teeb meem kev yees duab, nws yog siv hauv kev yees duab.
7.Oxygen scavenge: nws plays raws li cov pa scavenger tshem tawm cov pa yaj hauv dej khib nyiab thiab hauv cov kav dej.
8.Sodium metabisulfite tuaj yeem siv los ua tus thawj coj thaum lub sijhawm sib txuas ntawm cov polymerization ntawm polybutadiene nyob rau hauv cov cores ntawm vesicle membranes.
9.Nws tuaj yeem muab ntxiv ua antioxidant thaum lub sij hawm npaj cov kev daws teeb meem ntawm 6-hydroxydopamine hauv ntau yam kev tshawb fawb.
10.Dechlorination nyob rau hauv cov dej khib nyiab hauv nroog, pulp & ntawv, fais fab, thiab textile dej kho cov nroj tsuag.
