HPMC gel kub

Muaj ntau tus neeg siv tsis tshua them sai sai rau qhov teeb meem ntawm hydroxypropyl methyl cellulose HPMC gel kub. Niaj hnub no, hydroxypropyl methyl cellulose HPMC feem ntau yog qhov sib txawv los ntawm viscosity, tab sis rau qee qhov chaw tshwj xeeb thiab kev lag luam tshwj xeeb, tsuas yog viscosity ntawm cov khoom raug cuam tshuam. Tsis txaus, cov hauv qab no luv luv qhia txog hydroxypropyl methylcellulose HPMC gel kub.

Cov ntsiab lus ntawm pawg methoxy muaj feem cuam tshuam ncaj qha rau qib ntawm etherification ntawm cellulose ether. Cov ntsiab lus ntawm pawg methoxy tuaj yeem hloov kho los ntawm kev tswj cov mis, qhov kub thiab lub sijhawm teb. Tib lub sijhawm, qib ntawm etherification cuam tshuam rau qib ntawm kev hloov pauv ntawm hydroxyethyl lossis hydroxypropyl. Yog li ntawd, qhov khaws dej ntawm cellulose ether nrog qhov kub gel siab feem ntau yog qhov phem dua me ntsis. Cov txheej txheem tsim khoom no yuav tsum tau tshawb nrhiav, yog li nws tsis yog vim cov ntsiab lus methoxy qis, tus nqi ntawm cellulose ether qis, ntawm qhov tsis sib xws, tus nqi yuav siab dua.

QUALICELL's hydroxypropyl methyl cellulose HPMC hydroxypropyl cov ntsiab lus yog 25%. Qhov kub ntawm gel yog qhov tseem ceeb rau kev siv cellulose ether. Thaum qhov kub ntawm ib puag ncig tshaj qhov kub ntawm gel, cellulose ether yuav poob tawm ntawm dej thiab poob nws cov dej khaws cia. Qualicell's cellulose ether gel kub yog 65 degrees, uas tuaj yeem ua tau raws li qhov xav tau ntawm kev siv mortar thiab putty ib puag ncig (tshwj tsis yog rau ib puag ncig tshwj xeeb). Yog tias koj yuav QualiCell HPMC, thov qhia ua ntej yog tias koj muaj cov kev xav tau tshwj xeeb.
