Dab tsi yog Txoj Kev Ua Kom Zoo Ntawm Hydroxypropyl Methyl Cellulose (HPMC)?

Hydroxypropyl methyl cellulose (HPMC) yog cov khoom siv polymer feem ntau hauv kev lag luam tshuaj, zaub mov, thiab tshuaj pleev ib ce.Txoj kev sib cais ntawm HPMC tuaj yeem sib txawv nyob ntawm qhov kev npaj siv thiab kev siv ntawm cov khoom.

Nov yog qee txoj kev sib cais ntawm HPMC:

1. Stirring method: Txoj kev no suav nrog ntxiv ib qho tshwj xeeb ntawm HPMC rau cov kuab tshuaj thiab nplawm cov sib tov kom txog thaum lub polymer yaj tag.
2. Cov txheej txheem cua sov: Hauv txoj kev no, HPMC tau ntxiv rau cov kuab tshuaj thiab ua kom sov rau qhov kub thiab txias kom yooj yim rau kev sib cais.
3. Ultrasonic txoj kev: Txoj kev ultrasonic yuav ntxiv HPMC rau cov kuab tshuaj thiab subjecting cov sib tov rau ultrasonic tsis los txhawb lub dissolution ntawm lub polymer.
4. Txau kom qhuav txoj kev: Txoj kev no yuav ua rau HPMC yaj hauv cov kuab tshuaj, tom qab ntawd tshuaj tsuag kom qhuav cov tshuaj kom tau cov hmoov qhuav.
5. High-pressure homogenization txoj kev: Txoj kev no yuav tsum dissolving HPMC nyob rau hauv ib tug hnyav, ces muab cov kev daws rau high-pressure homogenization los pab txhawb lub dissolution txheej txheem.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qhov kev xaiv ntawm kev sib cais yog nyob ntawm qhov kev thov tshwj xeeb ntawm cov khoom HPMC thiab cov khoom xav tau ntawm cov khoom kawg.
