Kev Paub Txog Kev Lag Luam

Hydroxypropyl Methylcellulose (HPMC) yog ib qho polymer semi-synthetic, uas siv dav hauv ntau qhov chaw. HPMC yog ib qho hmoov dawb lossis dawb uas yaj tau zoo heev hauv dej thiab ruaj khov rau qhov kub.

Hydroxypropyl Methylcellulose (HPMC) yog ib qho khoom xyaw uas siv tau ntau yam hauv kev lag luam tshuaj.

Qhov ntxiv ntawm methylcellulose admixture rau hauv cement tuaj yeem muaj ntau yam teebmeem rau cov khoom siv kho tshuab ntawm cov khoom siv cementitious.

Hydroxypropyl Methylcellulose (HPMC) yog ib qho khoom siv ntxiv uas muaj txiaj ntsig zoo thiab siv tau ntau yam hauv kev lag luam kev tsim kho.

Cellulose ether yog siv dav hauv ntau yam khoom siv hauv tsev vim nws cov khoom siv tau ntau yam

Methyl cellulose ethers yog ib pawg ntawm cov cellulose derivatives uas tau hloov kho los ntawm kev qhia cov pab pawg methyl rau ntawm cellulose backbone. Cov derivatives no paub txog lawv cov dej-soluble thiab muaj ntau yam kev siv hauv kev lag luam xws li zaub mov, tshuaj, kev tsim kho, thiab tshuaj pleev ib ce. Nov yog qee hom methyl cellulose ethers:

Hydroxypropyl methylcellulose (HPMC) yog cov polymer uas yaj tau hauv dej uas feem ntau siv rau ntau yam kev siv, suav nrog ua tus neeg sawv cev tuab, tus khi

Hydroxyethylcellulose (HEC) yog ib qho polymer uas tsis yog ionic uas yaj tau hauv dej los ntawm cellulose. Nws siv rau ntau yam lag luam vim nws cov khoom ua kom tuab, ruaj khov, thiab ua zaj duab xis. Nov yog qee qhov kev siv Hydroxyethylcellulose:

Carboxymethyl Cellulose (CMC) yog ib qho cellulose derivative uas siv tau ntau yam thiab siv dav dav nrog ntau yam kev siv thoob plaws hauv kev lag luam.

Hydroxypropyl Methylcellulose (HPMC) yog cais ua cellulose ether thiab ua haujlwm ua ib qho khoom siv ntau yam hauv cov tshuaj formulations.
