Xaiv txoj cai hydroxyethyl cellulose (HEC) cov xim tuab rau cov khoom siv roj hmab, suav nrog lwm cov xim xim, thiab cov kev cai tshwj xeeb ntawm daim ntawv thov. Qhov kev qhia dav dav no yuav qhia tau tias cov kev txiav txim siab tseem ceeb los pab koj txiav txim siab ntawm kev xaiv hec thickeal rau koj cov xim looj xim.
1. Taw qhia rau looj xim tuab tuab:
1.1 rheological yuav tsum muaj:
Lasx pleev xim xav tau kev ntseeg rheology kom ua tiav qhov kev xav tau ua kom tiav, ruaj khov, thiab cov khoom siv. HEC yog ib qho kev xaiv ib txwm vim nws cov hauj lwm zoo hauv cov dej ua thickening.
1.2 Qhov tseem ceeb ntawm thickening:
Thickening cov neeg sawv ntxov txhim kho cov xim viscosity, tiv thaiv txhuam, txhim kho txhuam, txhim kho cov kev pab nqus / cov menyuam cov xim thiab muab cov puv.
2. Nkag siab hydroxyethyl cellulose (HEC):
2.1 Kev Siv Tshuaj thiab Khoom:
HEC yog dej-soluble polymer muab tau los ntawm cellulose. Nws tus qauv tshwj xeeb uas cuam tshuam cov khoom siv thiab kev ruaj khov rau cov xim pleev xim.
2.2 Cov qib ntawm HEC:
Cov qhab nia sib txawv ntawm HEC muaj, sib txawv hauv cov phaus molecular thiab hloov ntau cov qib. Qhov hnyav dua molecular hnyav thiab qhov hloov pauv tuaj yeem ua rau muaj peev xwm nce ntxiv.
3. Qhov ntau yam cuam tshuam HEC xaiv:
3.1 looj xim tsim:
Xav txog qhov tsim txhua yam, suav nrog cov hom luulation, pigments, fillers, thiab ntxiv, kom paub tseeb nrog kev xaiv tau nrog kev xaiv.
3.2 Xav tau Rheological Profile:
Txhais cov kev cai tshwj xeeb rheological rau koj cov xim looj kua yas, xws li shear thinning, leveling, thiab spoiled tiv taus.
4. Cov kev txiav txim siab tseem ceeb hauv HEC xaiv:
4.1 Viscosity:
Xaiv qib hec uas muab cov viscosity xav tau nyob rau hauv cov xim tha xim kawg. Kev coj ua viscosity ntsuas nyob rau hauv daim ntawv thov-cuam tshuam.
4.2 shear thinning yuavhavior:
Txheeb xyuas tus cwjp-theb-thev, uas cuam tshuam rau qhov yooj yim ntawm daim ntawv thov, qib, thiab ua yeeb yaj kiab tsim.
5.Uspatibility thiab stability:
5.1 Kev Sib Tw Tau:
Nco ntsoov tias HEC tau sib xws nrog cov latex polymer kom tsis txhob muaj teeb meem xws li theem sib cais lossis xiam kev ruaj khov.
5.2 PH rhiab heev:
Xav txog qhov rhiab phem ntawm HEC thiab nws cov kev cuam tshuam rau kev ruaj khov. Xaiv ib qib tsim nyog rau hom xim koj ntawm koj cov xim looj.
6.Application cov txuj ci:
6.1 txhuam thiab cov menyuam daim ntawv thov:
Yog tias txhuam thiab cov ntaub ntawv muab khoom siv yog ib qho muaj, xaiv HEC cov qib uas muab cov txhuam txhuam zoo / cov menyuam yaus tsis kam.
6.2 Tshuaj Tsuag Daim Ntawv Thov:
Rau cov ntawv thov txau, xaiv HEC qib uas tswj hwm kev ruaj khov thaum lub sij hawm atomization thiab ua kom muaj zog txawm tias txheej.
7. Kuaj thiab Tswj Xyuas Zoo:
7.1 Kev Ntsuam Xyuas Kev Tshawb Xyuas:
Kev ua haujlwm rau kev soj ntsuam kom ntsuas cov kev ua tau zoo ntawm HEC qib sib txawv raws li simulating tiag tiag-ntiaj teb daim ntawv thov.
7.2 Kev sim siab:
Ua daim teb raug mob kom siv tau cov kev tshawb pom kev kuaj nrhiav thiab saib xyuas qhov ua tau zoo ntawm kev xaiv HEC hauv cov xwm txheej pleev xim.
8. Cov kev txiav txim siab ib puag ncig thiab ib puag ncig:
8.1 Txoj Cai Raws Cai:
Xyuas kom cov kev xaiv hec ua raws li kev cai tswj cov kev cai rau cov xim thaib, xav txog yam xws li voc (volatile organic sib txuas) cov ntsiab lus.
8.2 Envirolal cuam tshuam:
Txheeb xyuas cov kev cuam tshuam ib puag ncig ntawm HEC thiab xaiv cov qib nrog kev rau qhov tsawg kawg nkaus.
9..Cov kev txiav txim siab:
9.1 tus nqi:
Txheeb xyuas tus nqi-ua tau zoo ntawm cov qhab nia sib txawv, txiav txim siab lawv cov kev ua tau zoo thiab cuam tshuam rau ntawm cov xim pleev xim tag nrho.
9.2 Cov saw muaj:
Xav txog cov kev muaj thiab kev ntseeg tau ntawm cov khoom siv muab rau cov HEC tau xaiv, ua kom zoo ua tau zoo.
10.Cov:
Xaiv txoj cai HEC Thickener rau looj cov xim yas yog qhov kev ntsuas kom zoo, sib xyaw, thiab kev txiav txim siab siv. Los ntawm kev xav txog cov xwm txheej no, koj tuaj yeem xaiv tus qib HEC uas ua kom raws li cov kev xav tau ntawm koj cov xim looj cov xim looj xim, kom ua tau zoo sib xws thiab qhov zoo hauv ntau qhov kev thov kev xaiv.
