Qhov teeb meem kub ntawm HPMC gel

Txog qhov teeb meem ntawm qhov kub ntawm gel ntawmHydroxypropyl Methyl Cellulose HPMC, ntau tus neeg siv tsis tshua them sai sai rau qhov teeb meem ntawm qhov kub ntawm Hydroxypropyl Methyl Cellulose. Niaj hnub no, Hydroxypropyl Methyl Cellulose feem ntau yog qhov sib txawv raws li nws cov viscosity, tab sis rau qee qhov chaw tshwj xeeb thiab kev lag luam tshwj xeeb, nws tsis txaus los tsuas yog cuam tshuam qhov viscosity ntawm cov khoom. Cov hauv qab no luv luv qhia txog qhov kub ntawm Hydroxypropyl Methyl Cellulose.

Tus nqi ntawm Methoxyl pawg yog ncaj qha cuam tshuam rau qib ntawm cellulose sourization, thiab cov ntsiab lus ntawm Methoxyl pawg tuaj yeem hloov kho los ntawm kev tswj cov mis, qhov kub thiab lub sijhawm teb. Tib lub sijhawm, qib ntawm inactivation 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 yuav tsis zoo. Cov txheej txheem tsim khoom no yuav tsum tau tshawb nrhiav, yog li nws tsis yog tias tus nqi tsim khoom ntawm cellulose ether qis yog tias cov ntsiab lus Methoxy qis, ntawm qhov tsis sib xws, tus nqi yuav siab dua.

Qhov kub ntawm cov gel yog txiav txim siab los ntawm cov pab pawg methoxyl, thiab qhov khaws dej yog txiav txim siab los ntawm cov pab pawg Hydroxypropoxy. Tsuas muaj peb pawg hloov tau ntawm cellulose. Nrhiav koj qhov kub siv tsim nyog, qhov khaws dej tsim nyog, thiab tom qab ntawd txiav txim siab tus qauv ntawm cov cellulose no.

Qhov kub ntawm cov gel yog qhov tseem ceeb rau kev sivcellulose etherThaum qhov kub thiab txias tshaj qhov kub ntawm gel, cov cellulose ether yuav raug sib cais ntawm cov dej thiab poob nws cov dej khaws cia. Qhov kub ntawm gel ntawm cellulose ether ntawm kev ua lag luam tuaj yeem ua tau raws li qhov xav tau ntawm qhov chaw siv mortar (tshwj tsis yog rau qhov chaw tshwj xeeb). Kuv tus kheej xav tias nws tsis tas yuav them sai sai rau qhov ntsuas kub ntawm gel thaum siv mortar. Tau kawg, kev tsim cov cellulose ether Cov chaw tsim khoom yuav tsum xav txog nws.
