Methyl ethyl hydroxyethyl cellulose (MEHEC) yog ib hom cellulose ether uas pom ntau yam kev siv thoob plaws kev lag luam sib txawv vim nws cov khoom tshwj xeeb. Cov tshuaj no yog ib qho derivative ntawm cellulose, ib txwm tshwm sim polymer pom nyob rau hauv cell phab ntsa ntawm cov nroj tsuag. MEHEC yog synthesized los ntawm cov txheej txheem tshuaj uas koom nrog etherification ntawm cellulose nrog methyl, ethyl, thiab hydroxyethyl pawg. Cov khoom sib xyaw ua ke nthuav tawm cov dej zoo khaws cia, thickening, zaj duab xis-tsim, thiab raug tshem tawm cov khoom, ua rau nws siv tau rau ntau yam kev siv.
1. Xim thiab Txheej:
MEHEC feem ntau yog siv los ua rheology modifier thiab thickener hauv cov xim dej thiab cov txheej txheem. Nws lub peev xwm los tswj cov viscosity thiab tiv thaiv cov xim xim ua rau nws tseem ceeb hauv kev tsim cov xim sab hauv thiab sab nrauv, primers, thiab coatings. MEHEC txhim kho cov khoom siv ntawm cov xim los ntawm kev tiv thaiv kev sib tsoo, ua kom muaj kev tiv thaiv ib puag ncig, thiab txhim kho kev txhuam hniav.
2.Cov khoom siv:
Hauv kev tsim kho kev lag luam, MEHEC tau siv ntau yam khoom xws li cement-based tile adhesives, grouts, thiab renders. Los ntawm kev tso dej tuav thiab ua haujlwm tau zoo rau cov ntaub ntawv no, MEHEC ua kom muaj dej kom zoo ntawm cov cement hais, txhim kho adhesion, thiab txo qis sagging los yog slumping thaum siv. Tsis tas li ntawd, nws txhim kho qhov sib xws thiab kev ua haujlwm ntawm cov cementitious formulations, ua rau lawv yooj yim dua.
3.Adhesives thiab Sealants:
MEHEC yog ib qho tseem ceeb additive nyob rau hauv kev tsim cov dej-raws li adhesives thiab sealants. Nws txhim kho cov tack, viscosity, thiab qhib lub sijhawm ntawm cov nplaum, ua kom yooj yim rau kev sib txuas ua haujlwm zoo ntawm cov substrates sib txawv. Nyob rau hauv sealants, MEHEC pab ua kom tiav extrudability, thixotropy, thiab adhesion, kom ntseeg tau zoo sealing ntawm cov pob qij txha thiab qhov khoob hauv kev tsim kho thiab kev siv tsheb.
4. Cov Khoom Siv Kho Tus Kheej:
Vim nws cov yeeb yaj kiab tsim thiab ua kom tuab, MEHEC tau siv ntau yam kev saib xyuas tus kheej thiab cov khoom siv tshuaj pleev ib ce. Nws tuaj yeem pom hauv cov tshuaj pleev, tshuaj pleev, tshuaj zawv plaub hau, thiab da dej gels, qhov twg nws txhim kho kev ntxhib los mos, ruaj khov, thiab moisturizing zog. MEHEC kuj tseem ua tus neeg sawv cev ncua rau cov khoom siv hauv cov txheej txheem kev saib xyuas tus kheej, tiv thaiv sedimentation thiab ua kom muaj kev faib tawm zoo ib yam.
5. Pharmaceuticals:
MEHEC ua haujlwm raws li kev sib khi, thickener, thiab stabilizer nyob rau hauv cov tshuaj formulations xws li ntsiav tshuaj, cream, thiab suspensions. Nws lub peev xwm los tswj cov viscosity thiab txhim kho cov khoom ntws kom ntseeg tau tias cov tshuaj sib xyaw ua ke thiab kev noj tshuaj zoo ib yam. Nyob rau hauv cov tshuaj pleev ib ce, MEHEC muab ib tug du thiab tsis-greasy kev ntxhib los mos thaum txhim kho cov adhesion ntawm cov khoom xyaw nquag rau ntawm daim tawv nqaij.
6. Kev lag luam zaub mov thiab dej haus:
Txawm hais tias tsawg dua piv rau lwm daim ntawv thov, MEHEC qee zaus siv hauv kev lag luam zaub mov thiab dej haus ua tus neeg sawv cev thickening thiab stabilizing. Nws tuaj yeem pom hauv qee yam khoom noj xws li kua ntses, hnav khaub ncaws, thiab dej haus, qhov twg nws txhim kho kev ntxhib los mos, qhov ncauj qhov ntswg, thiab txee ruaj khov yam tsis muaj kev hloov pauv saj lossis tsw.
7.Oil thiab Gas Kev Lag Luam:
MEHEC pom daim ntawv thov hauv cov dej drilling thiab cov cement slurries siv hauv kev lag luam roj thiab roj. Nws pab tswj cov kua dej viscosity, tshem tawm cov khoom siv, thiab tiv thaiv kom tsis txhob muaj dej thaum lub sijhawm ua haujlwm drilling. MEHEC-txhim kho cov kua dej ua kom muaj kev ruaj ntseg zoo, lubrication, thiab tshem tawm cov laum txiav, ua rau muaj kev vam meej tag nrho ntawm kev ua haujlwm drilling.
8. Textile Kev Lag Luam:
MEHEC yog siv nyob rau hauv textile printing thiab dyeing txheej txheem raws li ib tug thickener thiab rheology modifier rau luam pastes thiab dye da dej. Nws txhim kho qhov sib xws thiab ntws cov khoom ntawm luam ntawv pastes, kom ntseeg tau meej thiab zoo ib yam ntawm cov xim tso rau hauv cov khoom siv textile. MEHEC kuj tseem pab tiv thaiv cov xim los ntshav thiab txhim kho qhov ntse ntawm cov qauv luam tawm.
9.Lwm cov ntawv thov kev lag luam:
MEHEC pom ntau daim ntawv thov hauv kev lag luam xws li tshuaj ntxuav tes, ntawv tsim, thiab ceramics. Nyob rau hauv cov tshuaj detergents, nws txhim khu kev ruaj ntseg thiab rheology ntawm cov kua formulations, thaum nyob rau hauv daim ntawv manufacturing, nws txhim kho daim ntawv lub zog thiab tuav ntawm fillers thiab additives. Nyob rau hauv ceramics, MEHEC ua raws li ib tug binder thiab rheology modifier nyob rau hauv ceramic slurries, yooj yim shaping thiab molding txheej txheem.
methyl ethyl hydroxyethyl cellulose (MEHEC) yog ntau yam cellulose ether nrog kev siv dav hauv ntau lub lag luam. Nws qhov tshwj xeeb ua ke ntawm cov khoom, suav nrog cov thickening, dej tuav, kev ua yeeb yaj kiab, thiab kev ncua kev muaj peev xwm, ua rau nws muaj txiaj ntsig zoo ntxiv hauv cov qauv xws li cov xim thiab txheej rau cov khoom tu tus kheej, tshuaj, thiab lwm yam. MEHEC pab txhawb rau kev txhim kho cov khoom lag luam, kev ua tau zoo, thiab cov neeg siv khoom kawg ntawm kev siv ntau yam, yog li ua lub luag haujlwm tseem ceeb hauv ntau qhov kev lag luam.
