Hydroxyethyl cellulose (HEC) yog ib qho tseem ceeb uas tsis yog-ionic dej-soluble polymer compound nrog ntau yam kev siv hauv kev lag luam xim thiab txheej.
1. Thickener
Hydroxyethyl cellulose yog cov thickener zoo heev. Nws tuaj yeem ua kom cov viscosity ntawm cov xim los ntawm kev nqus dej hauv cov kua dej kom nthuav dav thiab tsim cov tshuaj colloidal. Qhov no tsis tsuas yog pab tiv thaiv cov xim los ntawm kev daws teeb meem thaum khaws cia thiab kev thauj mus los, tab sis kuj txhim kho nws cov qib thiab ncua kev kawm, kom ntseeg tau qhov sib xws thiab du ntawm cov xim txheej.
2. Rheological tswj
Hydroxyethyl cellulose tuaj yeem kho cov khoom rheological ntawm cov xim, uas yog, hloov nws cov yam ntxwv ntws ntawm cov nqi sib txawv. Nws tuaj yeem khaws cov xim ntawm ib qho viscosity hauv lub xeev zoo li qub los tiv thaiv sagging; thiab thaum lub sij hawm daim ntawv thov, viscosity yuav txo nrog qhov nce ntawm shear tus nqi, uas yog yooj yim rau kev tsim kho. Cov cuab yeej no pab txhim kho kev tsim kho thiab kev ua haujlwm ntawm cov xim.
3. Kev tuav dej
Hydroxyethyl cellulose muaj kev tuav dej zoo heev. Nws tuaj yeem tiv thaiv cov evaporation ntawm cov dej sai heev, yog li ncua lub sij hawm ziab ntawm cov xim thiab tso cai rau cov xim pleev xim kom muaj sij hawm txaus rau leveling thiab zaj duab xis tsim thaum lub sij hawm ziab. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog rau cov xim pleev xim rau hauv dej, vim tias qhov poob dej sai tuaj yeem ua rau muaj teeb meem xws li pinholes thiab tawg hauv cov xim pleev xim.
4. Kev ruaj ntseg thiab tiv thaiv kev daws teeb meem
Nyob rau hauv cov xim formulations, tshwj xeeb tshaj yog cov tshuab uas muaj cov pigments thiab fillers, hydroxyethyl cellulose tuaj yeem muab kev ncua kev ruaj ntseg zoo los ntawm thickening. Nws tuaj yeem tiv thaiv cov sedimentation ntawm cov xim thiab cov khoom ua kom zoo, ua kom cov xim sib xws ntawm cov xim thaum khaws cia, thiab ua kom cov xim sib xws thiab kev ua haujlwm ruaj khov ntawm txheej.
5. Txhim kho zaj duab xis-tsim cov khoom
Hydroxyethyl cellulose tuaj yeem txhim kho cov yeeb yaj kiab tsim cov xim ntawm cov xim. Nws tuaj yeem tsim ib txheej txheej zaj duab xis rau saum npoo ntawm txheej, txhim kho gloss thiab uniformity ntawm cov xim zaj duab xis. Tsis tas li ntawd, hydroxyethyl cellulose kuj tseem tuaj yeem txhim kho cov hmoov av thiab dej tsis kam ntawm cov yeeb yaj kiab txheej, ua kom nws cov kav ntev thiab cov khoom zoo nkauj.
6. Ib puag ncig tus phooj ywg khoom
Raws li non-ionic thickener, hydroxyethyl cellulose tsis muaj cov hlau hnyav thiab cov kuab tshuaj lom, thiab ua tau raws li kev tiv thaiv ib puag ncig. Nws siv hauv cov xim pleev xim rau hauv dej tuaj yeem txo cov ntsiab lus ntawm cov organic tsis sib haum xeeb (VOCs), uas pab txo cov pa phem rau ib puag ncig thiab ua rau tib neeg noj qab haus huv.
Daim ntawv thov ntawm hydroxyethyl cellulose hauv cov xim tsis tsuas yog txhim kho lub cev thiab kev tsim kho kev ua haujlwm ntawm cov khoom, tab sis kuj ua tau raws li kev tiv thaiv ib puag ncig thiab kev nyab xeeb ntawm kev lag luam niaj hnub coatings. Raws li ib tug multifunctional additive, nws plays lub luag hauj lwm tseem ceeb nyob rau hauv lub formulation tsim thiab daim ntawv thov txheej txheem ntawm cov xim.
