Hydroxyethyl cellulose (HEC) yog ib qho kev sib txuas ntxiv siv nyob rau hauv looj cov xim pleev xim rau nws cov khoom muaj ntau yam. Raws li cov dej-soluble polymer muab tau los ntawm cellulose, HEC muaj cov txiaj ntsig ntau rau cov xim pleev xim rau looj, kev ua haujlwm ruaj khov, thiab kev thov kev siv zog, thiab kev thov kev siv zog, thiab kev thov kev siv zog, thiab kev thov kev lag luam, thiab kev thov kev siv zog, thiab kev thov kev lag luam, thiab kev thov kev lag luam, thiab kev thov kev siv zog, thiab kev thov kev siv zog, thiab kev thov kev lag luam, thiab kev thov kev lag luam, thiab kev thov kev lag luam, thiab kev thov kev siv zog, thiab kev thov kev lag luam, thiab kev thov kev lag luam, thiab kev thov kev siv zog, thiab kev thov kev lag luam, thiab kev thov kev siv zog, thiab kev thov kev lag luam, thiab kev thov kev siv zog, thiab kev thov kev lag luam, thiab kev thov kev lag luam, thiab kev thov kev siv zog, thiab kev thov kev lag luam, thiab kev thov kev siv zog, thiab kev thov kev siv zog, thiab kev thov kev siv zog, thiab kev thov kev lag luam, thiab kev thov kev lag luam, thiab kev thov kev lag luam, thiab kev thov kev lag luam, thiab kev thov kev siv zog, thiab kev thov kev lag luam, thiab kev thov cov yam ntxwv.
1. Rheatorological tswj:
Viscosity Transpification: Hec Zoo hloov kho lub viscosity ntawm cov xim nplaum ntawm cov xim av zoo, muaj kev cuam tshuam lawv cov cwj pwm khiav thiab cov khoom siv. Los ntawm kev kho cov concentration ntawm HEC, pleev xim cov tuam ntxhab tuaj yeem ua tiav cov txiaj ntsig viscosity, yooj yim daim ntawv thov nrog txhuam, cov menyuam, lossis txaws.
Thixotropic Cwj Pwm: HEC CLICOROPS PIXOtropic cov khoom siv rau cov xim tsev zoo, lub ntsiab lus uas lawv muaj kev cuam tshuam qis dua nyob rau hauv kev nyuaj siab (thaum lub sijhawm viscosity) thiab siab dua viscosity ntawm so. Tus xeeb ceem no tiv thaiv sagging lossis dripping ntawm cov xim thaum daim ntawv thov thaum muaj kev tswj hwm ruaj khov thiab kev pab them nqi.
2. Txhim Kho Txiaj Ntsig:
Kev tiv thaiv kev ua kom muaj zog: kev tiv thaiv ua cov neeg sawv cev tuab dua, tiv thaiv kev daws teeb meem ntawm cov pigments thiab lwm yam khoom siv hauv cov xim looj. Qhov no ua kom muaj kev faib tawm cov khoom sib xyaw ntawm cov khoom siv thoob plaws cov xim tha xim, ua kom muaj kev ruaj ntseg thiab lub neej.
Txhim kho khov-yaj ruaj khov: Hi txhawb rau lub freex xim uas txwv tsis pub siv cov dej sib xyaw los ntawm kev sib cais los ntawm kev sib cais lossis theem sib cais thaum kub sib cais. Cov cuab yeej no yog qhov tseem ceeb rau cov xim pleev xim rau lossis siv cov huab cua txias.
3. Zaj duab xis tsim thiab adhesion:
Zaj duab xis Tsim: HEC ua kom yooj yim tsim kev tsim ntawm cov khaub ncaws hnav, cov yeeb yaj kiab du thaum ntxuav kom zoo nkauj ntawm cov xim tsev zoo. Nws txhawb nqa cov kev faib tawm ntawm txoj hlua khi thiab cov pigments, ua rau muaj cov yeeb yaj kiab zoo nkauj thiab kev pab them nqi.
Adhesion nce qib: Hec txhim kho cov nplaum ntawm cov xim nplaum ntawm cov xim pleev xim rau ntau hom substrates rau ntau yam av, suav nrog ntoo, hlau, thiab tshuab ziab khaub ncaws. Nws tsim cohesive matrix uas khi pigments thiab binders ua ke thaum txhawb nqa cov nplaum muaj zog rau cov sab nrauv.
4. Kev thov cov yam ntxwv:
Splates Restance: Cov xim pleev xim looj cov qauv tsim nrog HEC pom kev txo qis thaum daim ntawv thov, ua rau cov txheej txheem nqus tsev thiab ua kom cov txheej txheem pleev xim ntxiv.
Cov xim muaj zog thiab cov menyuam daim ntawv thov: HEC-hloov kho cov xim looj cov xim zoo thiab cov khoom siv kom du, muaj kev sib zog sib xyaw nrog kev siv zog tsawg.
5. Sib tsam thiab versatility:
Kev sib xyaw nrog cov quav ntxiv: HEC tau tshaj tawm ntau yam ntawm cov khoom ntxiv siv hauv cov xim sib ntxiv, suav nrog cov xim av zoo, suav nrog cov tshuaj tiv thaiv cov tshuaj txhuas, suav nrog cov tshuaj tiv thaiv cov tshuaj tsw qab, suav nrog cov yeeb yaj kiab, thiab cov xim. Qhov kev sib xyaw ua ke no ntawm cov xim hlau ntawm Hec-tau hloov kho, tso cai rau kev sib txuam ntawm ntau yam kev ua tau zoo ntxiv.
Dav Ph Ua siab ntev: HEC Cov Khoom Taw Qhia Zoo Kev Ruaj Ntseg thiab Kev Ua Tau Zoo Thoob Plaws, Ua Kom Tsim Nyog Rau Siv Nyob Hauv Cov Xim Alkaline thiab Acidic Xim.
6. Ib puag ncig thiab kev txiav txim siab nyab xeeb:
Dej-raws li daim qauv: Raws li cov dej-soluble polymer, HEC ua rau cov qauv ntawm cov phooj ywg ib puag ncig, cov dej ntws nrog cov khoom siv ntawm VOC tsawg) cov ntsiab lus. Qhov no ua kom haum nrog cov kev cai tswj hwm thiab cov neeg siv khoom nyiam rau kev ruaj khov, cov pa roj qis qis.
Tsis-toxicity: HEC yog tsis muaj tshuaj lom thiab muaj kev nyab xeeb rau siv nyob rau hauv looj cov xim zoo nkauj rau cov neeg ua haujlwm, cov neeg ua haujlwm, thiab cov neeg siv khoom tsawg kawg nkaus.
Hydroxyethyl cellulose (HEC) yog ib qho ntxiv additive uas muaj ntau ntau ntawm cov txiaj ntsig rau cov xim looj xim looj. Los ntawm rheatorological tswj thiab ruaj khov ua yeeb yam rau zaj duab xis thiab kev thov cov yam ntxwv, HEC ua tau lub luag haujlwm tseem ceeb hauv kev ua tau zoo thiab kev ua tau zoo ntawm cov xim huv. Nws cov kev sib raug zoo, ib puag ncig kev ua phooj ywg, thiab kev nyab xeeb ntxiv underscore nws tus nqi ua tus nyiam ntxiv hauv kev lag luam xim. Los ntawm kev siv tus yam ntxwv ntawm HEC, cov xim pleev xim tau tuaj yeem tsim cov txheej txheem ua tau zoo uas ua tau raws li cov neeg siv khoom uas ua raws li cov qauv kev tswj hwm.
