3. Daim Ntawv Thov:
Pobzeb Cov Ntawv Qhia: HPMC yog qhov dav dav hauv cov nplais nplaum nplaum txhawm rau txhawm rau txhim kho adhesion, kev ua haujlwm, thiab dej rov qab.
Masonry collove: hauv Masonry Mas, HPMC pab txhawb kev ua haujlwm tau zoo, ua kom zoo nkauj, thiab txo qis shrinkage.
Plastering cap: nws yog siv hauv plastering cap hlau kom txhim kho kev ua haujlwm, adhesion rau substrates, thiab kev tiv taus kom tawg.
Kev Ntsuas Tus Kheej: HPMC kuj tseem siv nyob rau hauv kev tswj hwm tus kheej los tswj cov khoom txaus thiab txhim kho saum npoo tiav.

4. DOSAGE THIAB POM ZOO:
Qhov ntau npaum ntawm HPMC txawv nyob ntawm kev ua haujlwm tshwj xeeb thiab cov qauv ntawm cov tshuaj khib.
Nws yog sib xws nrog lwm cov tshuaj ntxiv thiab admixtures feem ntau siv hauv cov mixed tsis muaj tshoob, xws li superplasticizers, thiab teeb tsa cov neeg sawv cev, thiab teeb tsa cov neeg sawv cev.

5. Cov qauv zoo thiab kev txiav txim siab:
HPMC siv hauv kev siv kev siv cov ntawv thov yuav tsum ua raws cov qauv kev ua tau zoo thiab cov kev qhia tshwj xeeb kom muaj xwm yeem thiab ua tau zoo.
Kev khaws cia zoo thiab tuav yog qhov tseem ceeb kom muaj txiaj ntsig ntawm HPMC, suav nrog kev tiv thaiv los ntawm kev tiv thaiv noo noo thiab huab cua sov heev.

6. Ib puag ncig thiab kev txiav txim siab nyab xeeb:
HPMC yog feem ntau suav tias muaj kev nyab xeeb rau kev siv hauv kev siv cov ntawv thov thaum daws raws li cov lus qhia uas pom zoo.
Nws yog biodegradable thiab tsis ua rau ib puag ncig tseem ceeb thaum siv raws li npaj siab.

HydroxyPropyyl methylcellulose (HPMC)yog ib qho ntau ntau yam zoo dua siv hauv cov khoom sib xyaw qhuav rau nws lub peev xwm los txhim kho, kev ua haujlwm zoo, dej ua tau zoo ntawm cov ntaub ntawv tsim kho. Nws cov kev sib xyaw nrog ntau yam kev ntxiv thiab cov ntawv thov hla cov khoom siv sib txawv ua rau nws muaj txiaj ntsig zoo hauv kev tsim kho niaj hnub no.
