Sodium Carboxymethyl cellulose (CMC-NA) yog cov polymer compound dav siv nyob rau hauv ntau tus neeg siv khoom. Hauv cov tshuaj txhuam hniav, sodium carboxymethyl cellulose plays lub luag haujlwm tseem ceeb, uas tau cuam tshuam hauv cov hauv qab no:
1. Thickening nyhuv
Sodium Carboxymethyl cellulose yog qhov ua tau zoo tuab uas tuaj yeem ua rau cov tshuaj txhuam hniav ntawm cov tshuaj txhuam hniav ntawm cov tshuaj txhuam hniav thiab ua kom cov tuab thiab tuab tuab. Tshuaj txhuam hniav uas yog yuag dhau yuav tsis yooj yim thov rau ntawm cov txhuam hniav thiab nws tsis yooj yim los tswj tus nqi ntawm kev siv; Yog tias nws yog ib yam nkaus thiab, nws yuav cuam tshuam kev nplij siab ntawm kev siv. Sodium Carboxymethyl cellulose tuaj yeem pab kho cov tshuaj txhuam hniav los ntawm cov tshuaj txhuam hniav tsis ntws nrawm nrawm lossis nyuaj rau nyem thaum siv.
2. Txhim Kho Kev Ruaj Ntseg
Cov tshuaj txhuam hniav cov tshuaj txhuam hniav ntau zaus muaj ntau yam xyaw, cov tshuaj fluoride, cov tshuaj ntxuav tes, ua rau cov tshuaj txhuam hniav, ua rau cov tshuaj txhuam hniav, ua rau cov khoom lag luam zoo thiab ua rau cov khoom lag luam zoo thiab cuam tshuam. Raws li cov tshuaj migh malecular hnyav, sodium carboxymethyl cellulose tuaj yeem cuam tshuam cov khoom xyaw ua ke los ntawm kev ruaj khov, thiab txhim kho kev ruaj ntseg ntawm cov khoom. Nws tuaj yeem siv los ua emulsifier los sib tov cov dej theem thiab cov roj Phase ense thiab tswj cov khaub ncaws ntawm cov tshuaj txhuam hniav.
3. Muab ua npuas ncauj ntev
Cov npaus hauv cov tshuaj txhuam hniav yuav pab ntxuav lub qhov ncauj thiab ua rau tus neeg siv ntxuav thiab xis huv dua. Sodium Carboxymethyl cellulose tsis tuaj yeem tsuas yog pab ua npuas ncauj xwb, tab sis kuj pab ua npuas dej kom nyob twj ywm thiab tiv thaiv kom tsis txhob ploj sai. Los ntawm kev txhim kho qhov ruaj ntseg ntawm cov npaus, cov nyhuv tu thiab siv cov tshuaj txhuam hniav uas tuaj yeem hloov kho. Tshwj xeeb tshaj yog rau cov tshuaj txhuam hniav uas nyob hauv qhov ncauj ntev, ua npuas ncauj zoo yog qhov tseem ceeb.
4. Txhim Kho Adhesion
Thaum siv cov tshuaj txhuam hniav, cov nplaum zoo tuaj yeem pab cov tshuaj txhuam hniav ayly npog cov hniav kom nquag tau tuaj yeem tiv toj rau cov hniav ntev, yog li ua si lub luag haujlwm zoo dua thiab tiv thaiv kev tiv thaiv zoo dua. Sodium Carboxymethyl cellulose tuaj yeem txuas rau cov nplaum ntawm cov hniav txhuam hniav, uas pab kom txo cov quav hniav txhuam hniav thiab txo qhov kev tsim ntawm Tartar.
5. Txhim kho qhov saj
Thaum siv tshuaj txhuam hniav, cov saj tseem yog qhov kev txiav txim siab tseem ceeb. Vim tias nws cov tshuaj ntxhib, sodium carboxymethyl cellulose tuaj yeem muab cov tshuaj txhuam hniav uas muab cov tshuaj txhuam hniav smoother, zam qhov tsis xis nyob los ntawm ntau lossis ntau dhau los yog ntau cov ntxhib. Ib qho ntxiv, nws kuj tseem tuaj yeem txhim kho cov tshuaj txhuam hniav ntawm lub qhov ncauj, zam kev sib txawv, thiab ua rau cov neeg siv xis nyob.
6. Kev Nyab Xeeb
Sodium Carboxymethyl cellulose yog cov tshuaj-cov khoom noj khoom haus feem ntau siv nyob rau hauv cov zaub mov thiab tshuaj, thiab nws txoj kev nyab xeeb yog qhov siab. Thaum siv cov tshuaj txhuam hniav, cov ntsiab lus feem ntau yog txoj kab nrog kev nyab xeeb qauv thiab yuav tsis ua kom raug mob rau tib neeg lub cev tom qab siv. Nws tsis yog-lom, tsis muaj kev txob taus, thiab yuav tsis thim ntawm tib neeg lub cev, uas tau raws li kev xav tau ntawm kev saib xyuas txhua hnub.
7. Txhim kho qhov cuam tshuam ntawm lwm cov khoom xyaw hauv cov mis
Hauv cov tshuaj txhuam hniav, ntxiv rau kev ntxuav kom huv, lwm yam khoom xyaw nquag xws li cov tshuaj fluoride feem ntau ntxiv. Cov tshuaj fluoride yog paub zoo rau nws cov nyhuv tiv thaiv ntawm cov hniav, tab sis nws nws tus kheej tau qee yam corrosiveness thiab reactivity. Yog tsis muaj lub mis tsim nyog, fluoride yuav hnov qab muaj kev cuam tshuam nrog lwm cov khoom xyaw, cuam tshuam rau cov tshuaj txhuam hniav thiab cov txiaj ntsig ntawm cov tshuaj txhuam hniav. Raws li lub stabilizer, sodium carboxymethyl cellulose tuaj yeem daws cov tshuaj nrog fluoride xws li ua kom lawv cov txiaj ntsig ntev.
8. Kev tiv thaiv ib puag ncig
Piv nrog lwm cov hluavtaws tshuaj, sodium carboxymethyl cellulose muaj kev tiv thaiv ib puag ncig dua. Nws yog yooj yim soluble hauv dej thiab tsis yooj yim rau kev ua qias neeg ib puag ncig, yog li nws tau siv dav hauv ntau cov neeg siv khoom txhua hnub. Siv sodium carboxymethyl cellulose ua ib qho ntawm cov tshuaj txhuam hniav yuav pab txo cov kev thaiv kev ib puag ncig.
Kev siv cov sodium carboxymethyl cellulose hauv cov tshuaj txhuam hniav tsis tuaj yeem tsuas yog txhim kho cov tshuaj txhuam hniav, ua npuas ncauj, xws li saj thiab ua kom huv. Raws li kev nyab xeeb thiab ib puag ncig tus phooj ywg polymer, qhov dav dav ntawm sodium carboxymethyl cellulity celliveness thiab kuj ua kom muaj kev nyab xeeb ntawm kev saib xyuas kev nyab xeeb txhua hnub.
