Methylhydroxyethylcellulose (MHEC) yog ib qho cellulose ether dav siv nyob rau hauv ntau yam lag luam, nrog rau lub tsev thiab kev tsim kho sector. Hauv architectural coatings, MHEC yog ib qho tseem ceeb thickener uas muab cov khoom tshwj xeeb rau txheej, yog li txhim kho nws cov kev ua tau zoo.
Taw qhia rau Methyl Hydroxyethyl Cellulose (MHEC)
MHEC yog ib qho uas tsis yog-ionic cellulose ether tau los ntawm ntuj polymer cellulose los ntawm kev hloov kho tshuaj lom neeg. Nws yog tus cwj pwm los ntawm kev sib xyaw tshwj xeeb ntawm methyl thiab hydroxyethyl pawg txuas rau nws cov pob txha cellulose. Cov qauv molecular no muab MHEC cov dej tuav tau zoo, ua kom tuab thiab ruaj khov, ua rau nws zoo tagnrho rau ntau yam kev siv hauv kev tsim kho kev lag luam.
Features ntawm MHEC
1. Rheological zog
MHEC paub txog nws cov khoom zoo rheological, muab cov viscosity zoo tagnrho thiab cov yam ntxwv ntws rau cov txheej. Cov nyhuv thickening yog ib qho tseem ceeb los tiv thaiv sagging thiab dripping thaum lub sij hawm thov thiab xyuas kom meej ib tug txawm thiab du txheej.
2. Kev tuav dej
Ib qho ntawm cov cwj pwm tseem ceeb ntawm MHEC yog nws lub peev xwm khaws dej. Qhov no yog ib qho tseem ceeb tshwj xeeb tshaj yog rau architectural coatings vim nws pab ncua lub sij hawm qhib ntawm cov xim, tso cai rau kom zoo leveling thiab txo lub peev xwm rau qhuav ntxov ntxov.
3. Txhim kho adhesion
MHEC txhim kho adhesion los ntawm kev txhim kho nto ntub dej, ua kom muaj kev sib cuag zoo ntawm cov txheej thiab substrate. Qhov no txhim kho adhesion, durability thiab tag nrho cov txheej txheem.
4. Kev ruaj ntseg
MHEC muab kev ruaj ntseg rau cov txheej txheem, tiv thaiv cov teeb meem xws li kev daws teeb meem thiab theem sib cais. Qhov no ua kom cov txheej txheem tswj nws qhov sib xws thoob plaws hauv lub txee lub neej thiab thaum siv.
Daim ntawv thov ntawm MHEC hauv architectural coatings
1. Xim thiab primer
MHEC yog siv dav hauv kev tsim cov xim sab hauv thiab sab nrauv thiab primers. Nws cov khoom thickening pab ua kom cov viscosity ntawm cov coatings, ua rau muaj kev tiv thaiv zoo dua thiab txhim kho daim ntawv thov kev ua haujlwm. Lub peev xwm tuav dej kom ntseeg tau tias cov xim yuav nyob twj ywm siv tau ntev.
2. Textured txheej
Hauv textured coatings, MHEC plays lub luag haujlwm tseem ceeb hauv kev ua tiav qhov kev xav tau zoo nkauj. Nws cov khoom rheological pab tusyees tshem tawm pigments thiab fillers, uas ua rau ib tug zoo ib yam thiab sib npaug textured tiav.
3. Stucco thiab Mortar
MHEC yog siv rau hauv stucco thiab mortar formulations los txhim kho workability thiab adhesion. Nws cov khoom tuav dej pab txuas ntxiv lub sijhawm qhib, ua rau muaj kev thov zoo dua thiab ua tiav cov khoom.
4. Sealants thiab Caulks
Architectural coatings xws li sealants thiab caulk tau txais txiaj ntsig los ntawm cov khoom thickening ntawm MHEC. Nws pab tswj qhov sib xws ntawm cov formulations no, ua kom muaj kev sib khi thiab kev sib khi zoo.
MHEC Qhov Zoo Tshaj Plaws hauv Architectural Coatings
1. Kev sib haum xeeb thiab kev sib koom siab
Kev siv MHEC ua kom ntseeg tau tias cov txheej txheem tsim vaj tsev muaj qhov sib xws thiab txawm tias muaj viscosity, yog li txhawb nqa txawm tias daim ntawv thov thiab kev pab them nqi.
2. Txuas sijhawm qhib
Cov khoom tuav dej ntawm MHEC txuas ntxiv lub sijhawm qhib ntawm cov xim, muab cov neeg pleev kob thiab cov neeg siv sijhawm ntxiv rau daim ntawv thov raug.
3. Txhim kho kev ua haujlwm
Nyob rau hauv stucco, mortar thiab lwm yam architectural txheej, MHEC txhim kho daim ntawv thov kev ua tau zoo, ua kom yooj yim rau cov neeg thov kom ua tiav qhov xav tau.
4. Txhim khu kev ruaj khov
MHEC pab txhim kho lub zuag qhia tag nrho durability ntawm txheej los ntawm kev txhim kho adhesion thiab tiv thaiv teeb meem xws li sagging thiab daws.
Methylhydroxyethylcellulose (MHEC) yog ib qho tseem ceeb thickener nyob rau hauv architectural txheej nrog ib qho tseem ceeb rheology thiab dej tuav cov khoom. Nws cuam tshuam rau kev sib xws, kev ua haujlwm thiab ua haujlwm ntev ua rau nws xaiv thawj zaug hauv kev tsim cov xim, primers, kev ntxhib los mos coatings, stucco, mortars, sealants thiab caulk. Raws li kev tsim kho kev lag luam txuas ntxiv mus, MHEC tseem muaj ntau yam thiab tseem ceeb hauv kev txhim kho cov txheej txheem kev ua haujlwm siab.
