HPMC sawv cev rau hydroxypropyl methylcellulose, cellulose derivative siv dav hauv kev tsim kho, suav nrog cov nplais nplaum.HPMC yog ib qho kev ua tau zoo ntxiv uas paub txog nws txoj kev siv ntau yam, lub zog thiab kev cia siab tau zoo.Hauv tsab xov xwm no, peb tshawb nrhiav lub luag haujlwm ntawm HPMC hauv cov nplais nplaum thiab nws tuaj yeem muaj txiaj ntsig zoo rau kev tsim kho kev lag luam.
1. Kev tuav dej
Ib qho ntawm cov haujlwm tseem ceeb ntawm HPMC hauv cov nplais nplaum yog dej tuav.HPMC absorbs noo noo thiab khaws cia rau lub sijhawm ntev, cov khoom tseem ceeb ntawm cov nplaum nplaum.Dej ua lub luag haujlwm tseem ceeb hauv cov nplais nplaum, ua kom muaj kev ua haujlwm thiab kub ua haujlwm ntawm cov nplaum slurry.HPMC txhim kho kev ua haujlwm thiab kev ua haujlwm ntawm cov nplais nplaum los ntawm kev ua kom cov dej evaporation qeeb, kom ntseeg tau tias qhov sib tov tseem ua haujlwm tau ntev dua.
2. Txhim kho kev ua haujlwm
Kev tsim kho ntawm pobzeb nplaum yog hais txog nws lub peev xwm los sib tov yooj yim, kis tusyees, thiab siv tusyees.HPMC txhim kho kev ua haujlwm ntawm cov nplais nplaum los ntawm kev ua cov roj nplaum thiab cov khoom tawg.Los ntawm kev ntxiv HPMC rau qhov sib tov, cov nplais nplaum ua kom yooj yim dua rau kev sib kis, ua kom muaj txiaj ntsig zoo hauv ntau yam kev siv.
3. Txhim kho lub sij hawm ua kom cov ntshav khov
Lub sijhawm teem sijhawm yog lub sijhawm nws siv rau cov pobzeb nplaum kom tawv thiab khi rau lub substrate.HPMC pab ncua lub sijhawm teem sijhawm ntawm cov nplais nplaum, tshwj xeeb tshaj yog thaum siv nrog lwm cov tshuaj ntxiv.Los ntawm kev siv HPMC, cov nplais nplaum tuaj yeem ua tiav qhov zoo tshaj plaws ntawm daim ntawv cog lus lub zog thiab ua haujlwm ntev los ntawm kev ua kom cov nplaum ua kom zoo.
4. Txhim kho adhesion
Adhesion yog hais txog lub peev xwm ntawm cov nplais nplaum kom ua raws li lub substrate.HPMC tuaj yeem txhim kho qhov adhesion ntawm cov nplais nplaum los ntawm kev ua kom muaj zog ntawm cov nplaum nplaum thiab qhov chaw nws tau siv rau.Cov cuab yeej no ua rau HPMC zoo tagnrho rau cov nplais nplaum vim nws ua kom cov vuas yuav tuav ruaj khov tom qab tso.
5. Zoo heev durability
HPMC yog ib qho zoo heev additives nyob rau hauv cov pobzeb nplaum vim nws muab durability thiab ntev lub zog rau kev sib raug zoo ntawm pobzeb thiab substrate.Cov cellulose nyob rau hauv HPMC txhim khu lub zog ntawm cov pobzeb nplaum, ua rau nws tiv taus cov dej thiab lwm yam khoom ib puag ncig uas tuaj yeem ua rau tsis muaj zog ntawm daim ntawv cog lus.HPMC kuj txhim kho kev yooj yim thiab pab tiv thaiv cov kab nrib pleb.
6. Ntau yam
HPMC yog cov khoom siv ntau yam uas tuaj yeem siv rau hauv ntau hom ntawv nplaum nplaum.Nws tuaj yeem siv nrog ntau hom pobzeb nplaum sib xyaw xws li cov vuas cement-based thiab cov vuas latex.HPMC tuaj yeem muab ntxiv rau hauv kev sib xyaw kom ntseeg tau tias cov nplais nplaum ua haujlwm tau zoo, ruaj khov thiab muaj peev xwm ua kom ruaj khov rau qhov sib txawv, txawm tias du lossis ntxhib.
nyob rau hauv xaus
Hauv cov ntsiab lus, lub luag haujlwm tseem ceeb ntawm HPMC hauv cov nplais nplaum tsis tuaj yeem tsis quav ntsej.HPMC txhim kho kev ua haujlwm thiab kev ua haujlwm ntawm cov pobzeb nplaum thaum txhim kho lawv cov kav ntev thiab yoog raws.Nws yog ib tug ntau yam additive uas yuav siv tau nyob rau hauv ntau yam ntawm cov pobzeb nplaum formulations.HPMC ua kom cov pobzeb nplaum muaj cov ntawv cog lus ntev, ua rau lawv xaiv zoo rau kev tsim kho kev lag luam.Yog li ntawd, HPMC yog ib qho tseem ceeb ntxiv rau hauv kev tsim cov nplais nplaum.
