Piv txwv li, hauv kev tsim cov tshuaj tiv thaiv kev ntshav siab, sodium methoxide yog siv los qhia cov pab pawg ua haujlwm tshwj xeeb lossis ua cov tshuaj tiv thaiv lub nplhaib thaum lub sijhawm tsim ntau kauj ruam.
Kev Txhim Kho Cov Txheej Txheem: Hauv cov txheej txheem tsim tshuaj, nws tuaj yeem siv los kho cov xwm txheej ntawm cov tshuaj, xws li pH, uas yog qhov tseem ceeb rau kev tsim thiab kev ntxuav cov tshuaj kom huv. Nws siv pab txhawb kev txhim kho cov txiaj ntsig ntawm cov tshuaj thiab xyuas kom meej tias cov khoom lag luam tshuaj zoo thiab sib xws.
3. Cov ntawv thov hauv Kev Lag Luam Khoom Noj
Kev Tsim Khoom Noj Khoom Haus: Txawm hais tias tsis tau ntxiv ncaj qha rau hauv cov khoom noj, sodium methoxide koom nrog kev tsim qee yam khoom noj khoom haus. Piv txwv li, hauv kev tsim cov tshuaj tsw qab lossis cov tshuaj antioxidants siv rau hauv cov khoom noj, nws tuaj yeem siv ua tus catalyst lossis reactant hauv cov txheej txheem tshuaj lom neeg. Los ntawm kev koom nrog cov tshuaj tiv thaiv no, nws pab tsim cov tshuaj uas txhim kho qhov saj, aroma, thiab lub neej txee ntawm cov khoom noj.
4. Cov ntawv thov hauv kev lag luam textile
Kev Kho Mob Fiber: Sodium methoxide siv tau rau hauv kev kho qee cov fibers. Nws tuaj yeem hloov kho cov yam ntxwv ntawm cov fibers, xws li txhim kho lawv cov xim - kev nqus tau. Hauv cov txheej txheem dyeing ntawm cov fibers raws li cellulose, piv txwv li, sodium methoxide siv tau los kho cov fibers ua ntej, ua rau lawv txais tau cov xim ntau dua. Qhov no ua rau cov ntaub ntawv ci ntsa iab dua thiab sai dua.
Kev Ua Tshuaj Lom Zem Rau Cov Ntaub Ntawv: Nws kuj siv rau hauv qee cov txheej txheem tshuaj lom neeg uas cuam tshuam nrog cov ntaub ntawv, xws li kev tsim cov tshuaj ua tiav rau cov ntaub ntawv. Cov tshuaj no tuaj yeem txhim kho kev ua tau zoo ntawm cov ntaub ntawv, xws li ua rau lawv tsis ntub dej, tiv taus hluav taws, lossis tiv taus kev ntsws.
5. Cov ntawv thov hauv kev lag luam roj teeb
Cheebtsam Electrolyte: Hauv qee hom roj teeb, tshwj xeeb tshaj yog nyob rau hauv qee lub tshuab electrolyte uas tsis yog dej, sodium methoxide tuaj yeem siv ua ib feem lossis ib qho khoom ntxiv. Nws tuaj yeem cuam tshuam rau kev ua haujlwm electrochemical ntawm lub roj teeb los ntawm kev cuam tshuam rau kev coj ua ntawm electrolyte, kev ruaj khov ntawm electrode - electrolyte interface, thiab tag nrho cov nqi - kev tso tawm haujlwm. Daim ntawv thov no yog qhov tseem ceeb tshaj plaws hauv kev txhim kho cov thev naus laus zis roj teeb rau cov tsheb fais fab thiab cov khoom siv hluav taws xob nqa tau.
