1. Cov ntsiab lus tseem ceeb ntawm CMC
CMC (Carboxymethyl cellulose) yog dav siv dej-soluble polymer compound, nrog dej solubility, thickening, gelling thiab emulsification ruaj khov. Nws tau txais los ntawm kev rov ua neeg lub ntuj cog cellulose (xws li ntoo pulp lossis paj rwb) nrog chloroacetic acid, feem ntau nyob rau hauv daim ntawv ntawm nws cov ntsev qab ntsev (cmc-na). Vim nws lub cev thiab tshuaj lom neeg tshwj xeeb, CMC tau siv dav hauv cov zaub mov, tshuaj, tshuaj pleev ib ce, cov tshuaj pleev roj, textiles, cov txheej txheem thiab lwm yam kev lag luam.
Hauv kev xaiv ntawm cov quav ntxiv, CMC muaj qhov zoo dua lwm cov kev sib ntxiv xws li gelatin, cov pos hniav, tshwj xeeb, emulsham, emulsification thiab ruaj khov.
2. Piv txwv zoo ntawm CMC
Thickening thiab gelling cov khoom
Raws li cov tuab, cmc muaj cov khoom siv zoo heev thiab ua kom zoo dua txhim kho lub viscosity thiab kev ruaj ntseg ntawm kev daws. Hauv cov khoom lag luam uas yuav tsum tau ua kom tuab, xws li cov khoom noj, tshuaj pleev ib ce, thiab nws cov nyhuv tuab heev yog qhov tseem ceeb tshaj li ntau cov polysaccharides.
Piv nrog lwm cov kev sib ntxiv, CMC tuaj yeem ua tiav cov teebmeem tuab tuab ntawm cov qis dua. Piv nrog cov tsiaj uas tau los ntawm cov tsiaj ua kom tuab li, cmc tuaj yeem tswj qhov ntsuas kub khov kho dua tshiab thaum qhov kub hloov lossis muaj cov acidic lossis cov pa alkaline. Nws tseem tuaj yeem tswj kev ua tau zoo, uas yog qhov tseem ceeb heev rau kev tsim cov khoom lag luam ntau.
Emulsification thiab ruaj khov
CMC muaj qhov zoo emulsification thiab ruaj khov, thiab tuaj yeem ua kom muaj txiaj ntsig dispersing thiab ruaj khov nyob rau hauv cov roj-dej emulsion tshuab. Hauv kev lag luam khoom noj khoom haus, cmc yog siv los ua kom muaj emulsions thiab kev noj haus, tshwj xeeb yog cov khoom noj khoom haus emulsion, tshwj xeeb tshaj plaws hauv kev haus dej paug, tshwj xeeb tshaj plaws hauv kev ua kom tawg thiab txuas ntxiv lub txee txee ntawm cov khoom lag luam.
Piv nrog ntuj emulsifiers xws li poss Arabic kev ua tau zoo, tshwj xeeb tshaj yog nyob rau hauv ntau cov acidic thiab neurral ib puag ncig, CMC tuaj yeem muab emulsification stability rau lub sijhawm ntev.
Kev Nyob Zoo thiab Tus Nqi Qis
CMC yog muab tau los ntawm cov nroj tsuag ntuj cog fibers, thiab cov txheej txheem ntau lawm tsis cuam tshuam cov txheej txheem kev nyuaj heev, uas yog qhov ruaj khov. Piv nrog qee cov tsiaj uas muaj tsiaj sib ntxiv (xws li gelatin), cmc tsis muaj cov khoom xyaw tsiaj, uas ua tau raws li cov khoom siv tsis tau ntawm cov tsiaj. Yog li ntawd, kev siv CMC yog ntau lub zej zog nyiam phooj ywg thiab ua tau raws li cov cai ntawm lub neej niaj hnub rau kev txhim kho kom ruaj khov.
Cov nqi ntau lawm ntawm CMC yog qhov tsawg, cov khoom siv raw, qhov chaw ntau lawm, thiab cov txheej txheem ntau lawm. Yog li ntawd, nyob rau hauv cov nqe lus ntawm cov nyiaj tau zoo, CMC muaj ntau dua ntxiv rau lwm cov kev sib ntxiv, tshwj xeeb hauv kev tsim khoom loj.
Dav hloov zuj zus
CMC muaj ntau cov kev siv hauv ntau thaj teb, emulsification, thiab cov tshuaj nplaum rau cov ntsiav tshuaj, thiab roj kev hauv kev lag luam roj. Nws tuaj yeem ua kom muaj kev ua tau zoo nyob rau hauv pH sib txawv, thiab salinity tej xwm txheej, yog li nws muaj qhov yoog tau.
Piv nrog lwm yam ntxiv, xws li HPMC (HydroxyPropyyl methylulose), CMC muaj ntau cov kev siv, tshwj xeeb hauv cov kev mob nyuaj. Txawm hais tias HPMC muaj zog zog ua kom muaj zog hauv qee kis, nws cov nyhuv tuab yog qis dua rau CMC, thiab nws cov nqi yog siab dua.
Tsis-toxicity thiab biocompatibility
Raws li cov dej-soluble polymer ntawm ntuj keeb kwm, cmc muaj zoo biocompatibility thiab qis toxicity thiab tau dav siv nyob rau hauv cov khoom lag luam thiab tshuaj pleev zaub mov thiab tshuaj pleev zaub mov. Nws tsis ua rau cov tshuaj tsis haum lossis tshuaj lom, thiab tsis pom tseeb kev sib txuam hauv tib neeg lub cev, ntsib cov qauv kev nyab xeeb zaub mov.
Piv nrog qee cov hluavtaws tshuaj ntxiv (xws li qee cov khoom siv hluavtaws lossis emulsifiers), CMC muaj kev nyab xeeb dua, thiab tsis muaj feem xyuam rau cov kev tsis zoo. Yog li no, kev siv CMC tau pom tseeb zoo hauv cov khoom uas muaj kev nyab xeeb ntawm kev nyab xeeb.
Ntau yam ntawm kev ua haujlwm
Ntxiv rau cov tuab thiab emulsification, cmc kuj tseem siv tau ua lub stabilizer, tsis txaus ntseeg tus neeg sawv cev, tus neeg saib xyuas tus neeg saib xyuas, thiab lwm yam, nrog ib qho kev ua haujlwm zoo dua. Nyob rau hauv cov tshuaj pleev ib ce kev lag luam, cmc tuaj yeem siv nyob rau hauv cov khoom xws li ntsej muag ntsej muag, tshuaj zawv plaub hau, thiab cov tawv nqaij pleev kom ntub dej, thiab ua kom tuab; Hauv kev lag luam khoom noj khoom haus, cmc feem ntau siv hauv kev haus, zaub xam lav, candies, thiab lwm yam khoom los txhim kho cov khoom ruaj khov thiab txhim kho cov khoom ruaj khov.
Piv nrog qee cov tshuaj ntxiv tshwj xeeb (xws li ib qho hluav taws xob ua lossis cov tawv nqaij tawv), CMC muaj kev xav tau ntau dua ntawm cov khoom sib txawv.
3. Ntsiab lus
Raws li kev sib txuam ua ke ntau ntxiv, CMC muaj ntau qhov zoo xws li thickening, emulsification, ruaj khov, thiab yog siv dav hauv ntau yam kev lag luam. Piv nrog rau lwm cov kev sib ntxiv, qhov zoo ntawm CMC yog qhov cuam tshuam hauv nws tus nqi ntau lawm, ib puag ncig zoo nkauj thiab kev nyab xeeb, thiab ntev ruaj khov. Yog li ntawd, CMC muaj txoj hauj lwm Irreplaceable hauv kev lag luam niaj hnub thiab yog tus nqi tsim nyog thiab muaj txiaj ntsig ntxiv.
