Carboxymetylcelleculose (CMC) yog qhov sib txuas ntau yam siv hauv ntau yam kev lag luam, suav nrog kev lag luam xab npum. Nws lub luag haujlwm hauv cov xab npum yog multifaceted, pab txhim kho kev ua kom tau zoo tag nrho thiab kev ua tau zoo ntawm cov khoom ntxuav.
1. Taw qhia rau Carboxymethylcelleculose (CMC):
Carboxymethylcellose yog dej-soluble polymer muab tau los ntawm cellulose, lub ntuj polymer pom hauv tsob ntoo phab ntsa. Los ntawm kev hloov kho tshuaj lom neeg, cov pab pawg carboxymethyl tau qhia rau hauv cov qauv cellulose los ua CMC. Cov degree ntawm kev hloov pauv (DS) qhia txog qib ntawm Carboxymethyl hloov hauv lub cellulose saw.
2. Cov qauv thiab kev ua tau zoo ntawm CMC:
Cov txheej txheem nta ntawm CMC yog cov saw ntev cellulose nrog cov pawg carboxymethyl. Tus qauv no muab cov khoom siv CMC ob peb cov khoom tseem ceeb, ua rau nws haum rau ntau cov ntawv thov:
Dej solubility: CMC yog soluble heev hauv dej, sib sau ua kom pom tseeb thiab muaj kuab. Cov cuab yeej no yog qhov tseem ceeb rau nws siv hauv cov qauv ua kua xws li xab npum.
Thickener: CMC ua raws li cov tuab dua, nce viscosity ntawm kev daws teeb meem. Qhov no muaj txiaj ntsig rau cov tshuaj ntxuav tes uas xav tau qee yam kev xav tau.
Zaj duab xis-ua cov khoom: CMC tuaj yeem tsim cov yeeb yaj kiab nyias nyias, uas tau txais txiaj ntsig zoo rau kev tsim cov yeeb yaj kiab tiv thaiv saum npoo thaum lub sijhawm ntxuav.
3. Lub luag haujlwm ntawm CMC hauv detergents:
Dej khaws cia thiab tshuaj xaub tawm: CMC txhim kho lub peev xwm ua kom muaj peev xwm ua kom muaj peev xwm ua kom ntub dej thiab tiv thaiv lawv tawm sai sai. Qhov no yog qhov tshwj xeeb tshaj yog qhov tshwj xeeb nrog cov tshuaj ntxuav kua, kom ua kom huv huv cov tshuaj ntxuav tau zoo rau ntev dua.
Kev ruaj ntseg ntawm cov qauv: CMC ua raws li lub stabilizer, tiv thaiv kev sib cais ntawm cov khoom xyaw txawv hauv cov tshuaj ntxuav ua kom huv. Nws pab tswj cov khoom lag luam thiab kev ruaj khov.
Viscosity tswj: Cov khoom tuab tuab ntawm CMC pab tswj lub viscosity ntawm kev daws teeb meem. Qhov no ua kom cov tshuab nqus kom muaj kev sib xws rau cov ntawv thov thiab cov nplaum.
Kev Tshem Tawm Av: CMC Txhim kho qhov kev ncua ntawm cov av tawm, tiv thaiv lawv los ntawm redepositing ntawm thaj chaw. Qhov no tseem ceeb heev rau tag nrho cov kev ntxuav tau yooj yim ntawm kev nqus kom huv.
Txhim kho foaming: hauv qee cov qauv, cmc tuaj yeem pab txhim kho kev ua npuas dej. Qhov no zoo nyob rau hauv cov ntawv thov uas ua npuas ncauj yuav tsum muaj rau cov kev pab them zoo dua thiab tu kom huv.
Compatibility nrog lwm cov khoom xyaw: CMC tau tshaj tawm ntau yam ntawm cov khoom xyaw xab npum, suav nrog surfactants thiab cov neeg tsim khoom. Qhov kev sib xyaw no ua rau muaj kev ruaj ntseg tag nrho thiab cov txiaj ntsig ntawm kev xab npum tshuaj ntxuav.
4. Kev cuam tshuam ntawm kev tu cev:
Ntxiv CMC mus rau cov tshuaj ua haujlwm tau muaj qhov cuam tshuam ncaj qha rau kev ntxuav ua tau zoo. Nws cov dej-khaws cia, thickening thiab ua yeeb yaj kiab-ua kom muaj zog kom ntseeg tau tias kev nqus tsev huv huv, zoo tshem cov av. Ib qho ntxiv, kev ncua ntawm cov av hais tiv thaiv lawv los ntawm kev sib luag rov qab mus rau qhov chaw huv.
5. Ib puag ncig kev txiav txim siab:
CMC yog suav tias yog tus phooj ywg ib puag ncig. Nws yog biodegradable thiab tsis ua rau ib puag ncig tseem ceeb thaum siv nyob rau hauv cov tshuaj ntxuav tes. Qhov no ua rau nws xaiv qhov tseem ceeb rau cov tuam ntxhab nrhiav cov khoom lag luam kom huv ntau.
6. Xaus:
Carboxymetylcellulose plays lub luag haujlwm tseem ceeb hauv cov tshuaj ntxuav ua kom huv. Nws cov khoom tshwj xeeb ua rau muaj kev ua tau zoo tag nrho, kev ruaj khov thiab ib puag ncig ua phooj ywg ntawm cov khoom ntxuav tu no. Raws li kev thov kom muaj kev ruaj khov thiab ua tau zoo xab npum txuas ntxiv mus, CMC feem ntau yuav nyob twj ywm rau cov khoom siv tseem ceeb rau kev lag luam. Nkag siab txog cov haujlwm thiab cov kev ua haujlwm ntawm CMC enables cov kws ua tiav los ua kom zoo rau cov tshuaj ntxuav ua kom zoo tshaj plaws kom huv siab.
