Kev siv Sodium Metabisulfite

Sodium metabisulfite (Na₂S₂O₅) yog ib qho tseem ceeb inorganic compound dav siv los ua preservative, antioxidant, bleaching agent, thiab txo tus neeg sawv cev. Ntawm no yog nws cov chaw siv tseem ceeb:

1. Kev lag luam zaub mov

· Preservation & Freshness: Inhibits kev loj hlob ntawm cov kab mob, pwm, thiab poov xab, ncua lub txee lub neej ntawm kua txiv, dej haus, cov kaus poom, txiv hmab txiv ntoo qhuav, thiab dehydrated zaub.

· Antioxidant: Tiv thaiv oxidative browning (xws li, hauv cov txiv hmab txiv ntoo thiab zaub) kom muaj xim thiab tsw.

· Bleaching Agent: Siv rau hauv bleaching qab zib, starch, candied txiv hmab txiv ntoo, thiab lwm yam, los txhim kho xim.

· Khoom noj khoom haus: Ua raws li lub khob noom cookie hloov hauv kev ci los txhim kho qhob cij zoo nkauj.

2. Kev lag luam dej haus

· Winemaking thiab Brewing:

· Inhibits cov kab mob qus, kom fermentation purity.

· Tiv thaiv oxidation hauv wines thiab beers, khaws cia tsw thiab xim.

· Tshem tawm cov tshuaj chlorine lossis impurities.

3. Kev lag luam kws tshuaj

· Excipient: Ua hauj lwm raws li ib tug antioxidant los tiv thaiv oxidation - cov tshuaj nquag (xws li, vitamin txhaj) thiab tswj kev ruaj ntseg.

· Siv me me hauv cov khoom siv tshuaj tua kab mob.

4. Kev kho dej

· Dechlorination: Tshem tawm cov chlorine seem ntawm cov kais dej los yog dej khib nyiab.

· Tus neeg saib xyuas txo: kho cov dej khib nyiab uas muaj cov hlau hnyav (xws li chromium) hauv cov txheej txheem kev lag luam.

5. Tshuaj & Kev Lag Luam Kev Lag Luam

· Tus neeg sawv cev txo qis: Siv rau hauv kev sib txuas cov dye intermediates, tawv tanning, roj hmab coagulation, thiab lwm yam.

· Bleaching Agent: Applied nyob rau hauv pulp thiab textile bleaching.

· Kev yees duab: Ib feem hauv kev daws teeb meem rau kev ua yeeb yaj kiab ib txwm muaj.

6. Lwm cov teb

· Kev Ua Liaj Ua Teb: Fumigant rau tom qab- khaws cia cov txiv hmab txiv ntoo thiab zaub (yuav tsum tau tswj kom nruj me ntsis).

· Laboratory: Txo tus neeg sawv cev los yog reagent hauv tshuaj ntsuam xyuas.

Cov Lus Cim Tseem Ceeb

· Kev txwv kev nyab xeeb: Cov khoom noj khoom haus yuav tsum ua raws li cov qauv hauv tebchaws (xws li Tuam Tshoj tus GB2760). Kev siv ntau dhau tuaj yeem ua rau tsis xis nyob hauv cov tib neeg rhiab heev (piv txwv li, cov neeg mob hawb pob).

· Kev Tswj Xyuas Kev Siv: Cov seem sulfur dioxide (SO₂) qib hauv cov zaub mov yuav tsum tau tswj, thiab daim ntawv lo yuav tsum yog tus qauv.

· Cia: Khaws rau hauv lub thawv kaw, lub teeb - tiv thaiv kom tsis txhob decomposition.

Hauv cov ntsiab lus, sodium metabisulfite yog ntau yam tshuaj ntxiv uas nws cov haujlwm tseem ceeb nyob hauv nws cov khoom txo qis thiab khaws cia. Nws yuav tsum tau siv lub luag haujlwm hauv cov cai tswj kev nyab xeeb.
