Kev ua tau zoo ntawm hydroxyethyl methylcellulose hauv cov nplais pobzeb nplaum: cov nyhuv anti-sag zoo, lub sijhawm qhib ntev, lub zog thaum ntxov, muaj zog kub hloov tau yooj yim, yooj yim rau do, yooj yim rau kev khiav lag luam, tsis-stick riam, thiab lwm yam.
Cov khoom siv
Dej solubility thiab thickening peev xwm: Hydroxyethyl methylcellulose yog soluble nyob rau hauv dej txias, tsim ib tug pob tshab thiab viscous kua.
Yooj yim soluble hauv cov kuab tshuaj organic: Vim muaj qee yam ntawm hydrophobic methoxy pawg, hydroxyethyl methylcellulose yog soluble hauv qee cov kuab tshuaj organic thiab cov kuab tshuaj uas cov dej thiab cov organic sib xyaw.
Salt kam rau ua: Txij li hydroxyethyl methylcellulose yog ib qho uas tsis yog-ionic, tsis yog-polymer electrolyte, nws yog ib qho ruaj khov nyob rau hauv aqueous daws ntawm hlau ntsev los yog organic electrolytes.
Deg kev ua si: Aqueous daws ntawm hydroxyethyl methylcellulose yog nto active thiab yog li ntawd muaj ib tug emulsifying nyhuv.
Thermal gelation: Thaum rhuab saum ib qho kub, cov tshuaj hydroxyethyl methylcellulose aqueous ua opaque thiab precipitates, ua rau cov tshuaj poob viscosity.Tab sis maj mam txias thiab hloov mus rau hauv thawj lub xeev daws teeb meem.Qhov kub ntawm qhov coagulation thiab nag lossis daus tshwm sim nyob ntawm seb hom khoom, qhov concentration ntawm cov tshuaj thiab cov cua kub npaum li cas.
Cov ntsiab lus tsis tshua muaj tshauv: Vim tias hydroxyethyl methylcellulose tsis yog-ionic thiab tuaj yeem ua kom zoo nrog dej kub thaum lub sijhawm npaj, cov hmoov tshauv tsawg heev.
PH stability: Lub viscosity ntawm hydroxyethyl methylcellulose aqueous tov yog tsis tshua muaj cuam tshuam los ntawm alkali.Cov khoom no kuj ruaj khov nyob rau hauv pH ntau ntawm 3.0-11.0.
Cov nyhuv dej khaws cia: Txij li hydroxyethyl methylcellulose yog hydrophilic thiab nws cov tshuaj aqueous muaj viscosity siab, ntxiv rau mortar, plaster, xim, thiab lwm yam.
Puab tuav: Piv nrog rau lwm cov dej-soluble polymers, aqueous tov ntawm hydroxyethyl methylcellulose muaj viscoelastic tshwj xeeb.Nws yog ntxiv ribbed los txhim kho lub peev xwm ntawm extruded ceramic khoom kom khaws lawv cov duab.
Lubricity: Ntxiv cov khoom no tuaj yeem txo qhov kev sib txhuam coefficient ntawm extruded ceramic khoom thiab cement khoom thiab txhim kho lubricity.
Cov khoom ua yeeb yaj kiab: Hydroxyethyl methylcellulose tuaj yeem tsim cov ntawv tawv, hloov tau, pob tshab nrog cov roj zoo thiab ester tsis kam.Nws tuaj yeem ua kom cov viscosity ntawm cov cement mortar zoo heev.Siv cov mortar tshiab nrog cov viscosity uas tsim nyog tuaj yeem nyob ruaj khov yam tsis muaj ntshav rau qee lub sijhawm, ua rau cov mortar yooj yim heev kom du thiab txhim kho kev tsim kho.
