EipponCell® HEC HS60000 Hydroxyethyl cellulose pom kev siv dav hauv kev lag luam xim thiab coatings, sawv tawm raws li cov khoom tseem ceeb.
Qhov tseeb, thaj av ntawm cov xim thiab cov txheej txheem yog qhov loj tshaj plaws rau kev siv HEC.Hauv qhov kev lag luam no, HEC siv lub luag haujlwm ntawm dispersant, thickener, thiab pigment suspending agent thaum lub sij hawm tsim cov xim latex.Nws cov kev pab yog multifaceted.Ua ntej, nws ua lub luag haujlwm tseem ceeb hauv kev ruaj khov ntawm cov viscosity ntawm cov xim, txo cov agglomeration, thiab ua kom cov xim zoo nkauj.Ntxiv mus, nws imparts zoo rheological zog rau cov xim latex, ua rau nws muaj peev xwm tiv taus siab zog thiab shear rog.Tsis tas li ntawd, HEC txhim kho cov xim ntawm qib, khawb tsis kam, thiab cov xim sib xws.
HEC kuj khav theeb ua haujlwm tshwj xeeb, tso cai rau cov xim tuab nrog HEC siv los ntawm ntau txoj kev tsim kho xws li txhuam, dov, txhaws, thiab tshuaj tsuag.Qhov kev ua tau zoo no ua rau muaj txiaj ntsig zoo xws li kev siv zog txo qis, txo qis qis thiab sagging, thiab txo qis splashing thaum siv.
Tsis tas li ntawd, HEC nthuav tawm cov xim zoo nkauj thiab nthuav tawm kev sib raug zoo nrog feem ntau ntawm cov xim thiab cov binders.Qhov kev sib raug zoo no txhais ua cov xim latex tsim nrog HEC muaj cov xim tshwj xeeb sib xws thiab ruaj khov, yog qhov tseem ceeb hauv kev lag luam xim thiab txheej txheej.
