Sodium metabisulphite (Na2S2O5) yog cov xim tsis muaj xim crystalline hmoov dav siv hauv zaub mov, tshuaj pleev ib ce, tshuaj thiab textiles teb, thiab yog ib qho tseem ceeb sulphite compound.Nws yog tsim los ntawm ob sulfinyl ions thiab ob sodium ions.Nyob rau hauv acidic tej yam kev mob, sodium metabisulphite yuav decompose rau hauv sulfur dioxide, dej thiab sulphite, yog li nws yog dav siv nyob rau hauv cov khoom noj thiab dej haus kev lag luam, ua si ib tug tshuaj tua kab mob, sterilization thiab antioxidant lub luag hauj lwm.
1. Cov qauv tshuaj thiab cov khoom ntawm sodium metabisulphite
Sodium metabisulphite muaj lub cev tseem ceeb thiab tshuaj lom neeg, nws cov mis molecular yog Na2S2O5, qhov txheeb ze molecular loj yog 190.09 g / mol, qhov ceev yog 2.63 g / cm³, lub melting point yog 150 ℃, boiling point yog hais txog 333 ℃.Sodium metabisulphite yog siv lead ua tsis muaj xim yooj yim soluble hauv dej thiab glycerol, ruaj khov hauv cov tshuaj alkaline, thiab yooj yim decomposed rau hauv sulfur dioxide thiab sulphite ions nyob rau hauv acidic tej yam kev mob.Sodium metabisulphite yog ruaj khov nyob rau hauv cov huab cua qhuav, tab sis tawg nyob rau hauv cov huab cua ntub los yog kub kub.
2. Daim ntawv thov teb ntawm sodium metabisulphite
Sodium metabisulphite yog cov khoom noj khoom haus uas tau siv dav, nws yog siv rau hauv cov khoom noj nqaij, cov khoom siv hauv dej, dej haus, malt dej haus, kua ntses thiab lwm yam khoom noj ua antioxidant, preservative thiab bleach.Nws kuj tseem siv tau los ua cov khoom qab zib xws li khoom qab zib, cov kaus poom, jams thiab khaws cia kom lawv lub neej txee thiab saj.Sodium metabisulphite kuj tseem siv tau los ua cov khoom siv hauv kev lag luam roj, tshuaj dawb hauv cov ntawv lag luam, tshuaj ntxiv, thiab tshuaj ntxiv rau hauv dyes thiab textile processes.
3. Mechanism ntawm kev ua ntawm sodium metabisulphite
Lub luag haujlwm tseem ceeb ntawm sodium metabisulphite ua cov khoom noj khoom haus ntxiv yog ua antioxidant thiab preservative.Nws tuaj yeem cuam tshuam cov oxidation ntawm cov rog hauv cov zaub mov, ua kom cov zaub mov tsis zoo, thiab yog li txuas ntxiv lub txee lub neej ntawm cov zaub mov.Nyob rau tib lub sijhawm, sodium metabisulphite tuaj yeem cuam tshuam kev loj hlob ntawm cov kab mob thiab pwm hauv cov zaub mov thiab zam cov khoom noj los ntawm cov kab mob.Qhov no antioxidant thiab antibacterial nyhuv yog tiav los ntawm sulfur dioxide thiab sulphite ions uas ua los ntawm decomposition ntawm sodium metabisulphite.
Ntxiv nrog rau nws daim ntawv thov hauv kev lag luam ua zaub mov, sodium metabisulphite kuj tseem siv tau los ua cov tshuaj hauv lwm qhov chaw, xws li roj catalysts, tshuaj dawb, tshuaj additives, thiab lwm yam. kuj txawv, tab sis lawv txhua tus muaj feem xyuam rau lawv cov antioxidant, antiseptic, bactericidal thiab bleaching zog.
4.Kev nyab xeeb thiab ib puag ncig cuam tshuam ntawm sodium metabisulphite
Sodium metabisulphite yog cov tshuaj siv dav, thiab nws qhov cuam tshuam rau tib neeg kev noj qab haus huv thiab kev nyab xeeb ib puag ncig tau nyiam ntau yam.Feem ntau, sodium metabisulphite muaj kev nyab xeeb rau kev siv nyob rau hauv qhov ntau npaum li cas.Txawm li cas los xij, yog tias siv ntau dhau thiab ua rau lub sijhawm ntev mus rau qhov siab ntawm sodium metabisulphite yuav muaj qee yam cuam tshuam rau tib neeg kev noj qab haus huv, xws li tawv nqaij khaus, ua tsis taus pa, ua xua, thiab lwm yam. Tsis tas li ntawd, sodium metabisulphite hauv cov txheej txheem decomposition los tsim sulfur dioxide. kuj tseem tuaj yeem tsim SOx (sulfur oxides) thiab lwm yam kuab paug, ua rau muaj kev cuam tshuam tsis zoo rau ib puag ncig.Yog li ntawd, thaum siv sodium metabisulphite, kev tswj hwm thiab kev saib xyuas kev nyab xeeb yuav tsum tau ua kom tsis txhob muaj kev phom sij thiab kev cuam tshuam ib puag ncig.
Hauv kev luv luv, sodium metabisulphite yog cov tshuaj siv dav siv, uas yog cov khoom siv tshuaj tseem ceeb hauv kev ua zaub mov, tshuaj pleev ib ce, tshuaj thiab textiles.Nws muaj ntau yam kev ua haujlwm xws li kev tiv thaiv oxidation, tiv thaiv corrosion, sterilization, bleaching thiab lwm yam, thiab yog ib qho tseem ceeb tshuaj nyob rau hauv ntau lub teb.Txawm li cas los xij, nyob rau hauv tus txheej txheem ntawm kev siv, nws tseem yuav tsum tau ua tib zoo saib xyuas cov teeb meem ntawm kev nyab xeeb thiab kev tiv thaiv ib puag ncig txhawm rau txhawm rau muab kev ua si tag nrho rau nws cov txiaj ntsig zoo thiab tsis txhob cuam tshuam rau tib neeg kev noj qab haus huv thiab ib puag ncig.
