1. Txheej txheem cej luam
Methyl Hydroxyethyl Cellulose (MHEC), tseem hu ua Hydroxyethyl Methyl Cellulose, yog ib qho nonionic cellulose ether. Nws cov qauv molecular yog tau los ntawm kev qhia methyl thiab hydroxyethyl pawg rau hydroxyl pawg hauv cellulose molecule. Vim nws qhov tshwj xeeb ntawm lub cev thiab tshuaj lom neeg, MHEC tau siv dav hauv ntau qhov chaw xws li kev tsim kho, txheej, thiab tshuaj pleev ib ce.
2. Qhov zoo ntawm MHEC
Kev ua haujlwm thickening zoo heev
MHEC muaj peev xwm thickening zoo thiab tuaj yeem yaj hauv dej thiab polar organic solvents los tsim cov kev daws teeb meem pob tshab thiab ruaj khov. Lub peev xwm thickening no ua rau MHEC zoo heev hauv cov qauv uas yuav tsum tau hloov kho cov khoom rheological.
Kev tuav dej zoo
MHEC muaj cov dej tuav tseem ceeb thiab tuaj yeem txo cov dej evaporation hauv cov khoom siv hauv tsev. Qhov no yog qhov tseem ceeb los txhim kho cov txheej txheem ntawm cov khoom siv thiab kev ua haujlwm ntawm cov khoom kawg (xws li lub zog thiab tawv).
Zoo heev film-forming zog
MHEC muaj peev xwm tsim tau ib qho tawv, pob tshab zaj duab xis thaum ziab, uas yog qhov tseem ceeb tshwj xeeb hauv cov txheej txheej thiab cov nplaum, thiab tuaj yeem txhim kho qhov adhesion thiab durability ntawm txheej.
Cov khoom siv tshuaj ruaj khov
Raws li cov non-ionic cellulose ether, MHEC muaj kev ruaj ntseg zoo rau cov kua qaub, alkalis thiab ntsev, tsis yooj yim cuam tshuam los ntawm ib puag ncig yam, thiab tuaj yeem nyob ruaj khov tshaj pH ntau yam.
Tsawg khaus thiab kev nyab xeeb
MHEC tsis muaj tshuaj lom thiab biodegradable, tsis ua rau tib neeg lub cev, thiab yog siv dav hauv cov khoom tu tus kheej thiab cov zaub mov, ua tau raws li ntau yam kev nyab xeeb thoob ntiaj teb.
3. Cov ntawv thov tseem ceeb ntawm MHEC
Cov khoom siv hauv tsev
MHEC yog dav siv los ua ib qho ntxiv rau cov cement-based thiab gypsum-raws li cov ntaub ntawv hauv tsev, xws li putty hmoov, mortar, adhesives, thiab lwm yam. adhesion thiab compressive zog ntawm cov khoom kawg. Piv txwv li, hauv cov nplais nplaum nplaum, MHEC tuaj yeem muab cov nplaum nplaum zoo thiab qhib lub sijhawm, thiab txhim kho cov nyhuv adhesion ntawm cov vuas.
Xim kev lag luam
Hauv cov xim, MHEC yog siv los ua cov thickener thiab stabilizer los txhim kho lub fluidity thiab cia ruaj khov ntawm cov xim, thaum txhim kho cov yeeb yaj kiab tsim thiab tiv thaiv sagging ntawm txheej. MHEC tuaj yeem siv rau sab hauv thiab sab nrauv phab ntsa pleev xim, xim xim dej, thiab lwm yam los xyuas kom meej tias cov xim sib npaug sib npaug thaum tsim kho thiab txhim kho cov kav ntev thiab tiv thaiv fouling ntawm txheej.
Cov Khoom Siv Kho Tus Kheej
MHEC yog dav siv nyob rau hauv cov khoom siv tu tus kheej xws li tshuaj zawv plaub hau, tshuaj pleev ib ce, tshuaj pleev ib ce, thiab lwm yam. Nws tuaj yeem txhim kho qhov kev ntxhib los mos ntawm cov khoom, ua kom nws smoother, thiab txhim khu kev ua tau zoo ntawm cov khoom tu tawv nqaij thiab cov khoom tu plaub hau.
Tshuaj thiab zaub mov
Hauv kev lag luam tshuaj, MHEC tuaj yeem siv rau kev tswj cov tshuaj tso tawm txheej, thickening ncua kev kawm ntawv, thiab lwm yam hauv cov khoom noj, MHEC tuaj yeem siv los ua cov thickener thiab stabilizer los txhim kho cov saj thiab ruaj khov ntawm cov khoom, thiab ua cov roj hloov kom txo cov calories. .
Adhesives thiab sealants
MHEC tuaj yeem siv los ua cov thickener thiab stabilizer hauv cov nplaum thiab cov sealants los muab cov viscosity zoo thiab dej tsis kam. Nws tuaj yeem siv rau hauv daim ntawv thov xws li kev sib txuas ntawm daim ntawv, textile bonding thiab lub tsev sealing los xyuas kom meej qhov ua tau zoo thiab ruaj khov ntawm cov nplaum.
Roj Drilling
MHEC yog siv los ua ib qho tshuaj ntxiv los tswj cov rheology ntawm cov roj drilling kua, uas tuaj yeem txhim kho cov dej drilling lub peev xwm los nqa cov txiav, tswj dej poob, thiab txhim kho kev ua haujlwm drilling.
4. Txoj Kev Loj Hlob thiab Kev Ua Lag Luam Zoo
Nrog rau kev txhim kho txuas ntxiv ntawm kev tsim kho kev lag luam, cov khoom siv tu tus kheej, thiab kev lag luam coatings, qhov kev thov rau MHEC tseem nce ntxiv. Yav tom ntej, kev lag luam kev cia siab ntawm MHEC tau cog lus tseg, tshwj xeeb tshaj yog nyob rau hauv cov ntsiab lus ntawm kev xav tau ntau ntxiv rau cov khoom siv ntsuab thiab ib puag ncig zoo. Nws biodegradable thiab muaj kev nyab xeeb thiab tsis muaj tshuaj lom cov yam ntxwv yuav ua rau nws siv tau rau ntau qhov chaw tawm tshiab.
Kev kawm txuj ci tau txhawb kev ua kom zoo ntawm MHEC cov txheej txheem tsim khoom, txo cov nqi tsim khoom, thiab txhim kho cov khoom zoo thiab kev ua haujlwm. Cov lus qhia kev tshawb fawb yav tom ntej yuav tsom mus rau kev txhim kho kev ua haujlwm ntawm MHEC, xws li los ntawm kev qhia cov pab pawg sib txawv lossis tsim cov khoom sib xyaw los txhim kho nws cov kev ua tau zoo hauv cov ntawv thov tshwj xeeb.
Methyl hydroxyethyl cellulose (MHEC) tau ua kom pom ntau yam ntawm daim ntawv thov muaj peev xwm hauv ntau qhov kev lag luam nrog nws cov thickening zoo heev, dej tuav, zaj duab xis-tsim thiab ruaj khov tshuaj. Nws ua lub luag haujlwm tseem ceeb hauv cov khoom siv hauv tsev, txheej txheej, kev saib xyuas tus kheej, tshuaj, zaub mov thiab lwm yam kev lag luam, thiab nrog kev nce qib ntawm cov cuab yeej technology thiab kev hloov pauv hauv kev xav tau ntawm kev lag luam, daim ntawv thov daim teb thiab kev lag luam loj ntawm MHEC yuav tsum tau nthuav dav ntxiv.
