HEC muaj kev ua haujlwm ntawm thickening thiab txhim kho lub zog tensile ntawm txheej hauv cov xim latex.
HEC (Hydroxyethyl cellulose) yog cov dej-soluble polymer nrog viscosity hloov kho, soluble hauv dej thiab cov kuab tshuaj organic, thiab tuaj yeem tsim cov emulsions ruaj khov hauv dej.Nws muaj kev ua haujlwm zoo halogen, kub thiab alkali tsis kam, thiab tshuaj lom neeg ruaj khov.HEC yog siv los txhim kho cov viscosity ntawm latex xim, stabilize cov khoom ntawm cov mis, tiv thaiv cov agglomeration ntawm latex xim, txhim kho cov adhesion, tensile zog, yooj thiab hnav tsis kam ntawm txheej zaj duab xis, uas yog ib qho kev tivthaiv ntawm kev loj hlob. high-quality latex xim.
Lub luag haujlwm tseem ceeb ntawm HEC yog txhawm rau txhim kho cov khoom siv kho tshuab ntawm txheej txheej.Nws kuj tuaj yeem siv los ua tus neeg sawv cev tiv thaiv sedimentation, preservative lossis anti-viscosity tus neeg sawv cev.Yog tsis muaj HEC concentration, nws tuaj yeem ua kom cov viscoelasticity ntawm txheej txheej, ua kom lub zog tensile thiab yooj ntawm txheej, thiab tshem tawm cov shrinkage thiab tawg ntawm zaj duab xis.
Hydroxyethyl cellulose muab cov txheej txheem zoo heev rau cov txheej txheem latex, tshwj xeeb tshaj yog cov txheej PVA siab.Thaum lub txheej yog tuab, flocculation yuav tsis tshwm sim.
Hydroxyethyl cellulose muaj cov nyhuv thickening ntau dua.Nws tuaj yeem txo qhov ntau npaum li cas, txhim kho kev lag luam ntawm cov mis, thiab txhim kho cov tshuaj txhuam hniav ntawm txheej.
Cov tshuaj aqueous ntawm hydroxyethyl cellulose yog non-Newtonian, thiab cov khoom ntawm cov tshuaj hu ua thixotropy.
Nyob rau hauv lub xeev zoo li qub, txheej txheej txheej tseem thickened thiab qhib tom qab cov khoom tiav lawm.
Nyob rau hauv lub xeev poured, lub kaw lus tswj ib tug nruab nrab degree ntawm viscosity, ua rau cov khoom muaj zoo fluidity, thiab tsis txaws.
Nyob rau hauv cov txhuam thiab yob txheej, cov khoom yog ib qho yooj yim mus kis rau ntawm lub substrate.Yooj yim rau kev tsim kho.Nyob rau tib lub sij hawm, nws muaj zoo splash kuj.Thaum lub txheej tiav lawm, lub viscosity ntawm lub system yog rov qab tam sim ntawd, thiab txheej tam sim ntawd ua ntws dai.
