Cov khoom lag luam
Hydroxyethyl cellulose (HEC) yog cov dej-soluble polymer compound nrog cov tshuaj muaj tshuaj [C6h7o2 (Oh) 2oC2h4oh Nws yog xim dawb lossis me ntsis daj ua hmoov me, tsis muaj ntxhiab tsw qab ntawm 0.55 ~ dog dig, lossis swells hauv butyaltraldehyde thiab acetic acid. HEC tsis muaj ionize hauv dej, muaj cov kua qaub zoo thiab alkali tsis kam, thiab tsis muaj kev cuam tshuam nrog cov hlau hnyav los ua cov dej nag. Thaum ph <3, HEC yuav acidolyze kom txo cov viscosity ntawm cov kua aqueous. Nyob rau hauv qhov kev txiav txim ntawm muaj zog alkali, HEC yuav yauv yais oxidative oxidative ntawm cov aqueous kev daws yuav txo qis vim kub thiab lub teeb. Nws yog ruaj khov nyob rau hauv lub phua ntawm 6.5 ~ 8.0.
Cov khoom lag luam
1. HEC yog Soluble nyob rau hauv dej kub lossis dej txias, thiab tsis precipitate ntawm qhov kub lossis rhaub, uas ua rau nws muaj ntau yam ntawm solubility, thiab tsis-thermal gelation;
2. Nws yog tsis-ionic thiab tuaj yeem uake nrog lwm cov dej-soluble polymers, solfactants, thiab salts hauv ntau yam. Nws yog qhov zoo tshaj plaws colloidal tuab rau cov kev daws teeb meem dientectrtric;
3
4. Piv nrog lees paub methyl cellulose thiab hydroxypropyl cellulose, HEC muaj qhov phem tshaj plaws, tab sis muaj zog tiv thaiv kev tiv thaiv muaj peev xwm.
