• Kev sib xws: Xyuas kom meej tias daim ntawv thov sib xws yam tsis muaj sagging.

4. Cov Tshuaj Sib Xyaws Uas Ua Rau Nws Tus Kheej Zoo Li Qub

Rau cov ntaub ntawv self-leveling, HPMC ua kom muaj kev ntws zoo thiab kev teeb tsa tus cwj pwm.
Cov Kev Cuam Tshuam Tseem Ceeb:

• Kev Tswj Xyuas Qhov Ntsws: Pab ua tiav qhov ntws xav tau thaum tswj kev ruaj khov.
• Kev Txo Qhov Kev Ntshai Ntawm Huab Cua: Txo cov npuas dej, ua rau qhov chaw du.
• Kev ruaj khov: Pab txhawb rau lub zog thiab kev ruaj khov mus sij hawm ntev.

5. Cov Txheej Txheem Rwb Thaiv Sab Nraud thiab Cov Txheej Txheem Ua tiav (EIFS)

HPMC yog siv los txhim kho cov khoom ntawm cov nplaum mortars thiab cov tsho tiv no hauv EIFS.
Cov Kev Cuam Tshuam Tseem Ceeb:

• Kev Tiv Thaiv Huab Cua: Ua kom ruaj khov dua thaum muaj ntau yam xwm txheej ib puag ncig.
• Kev ywj pheej: Txo qhov brittleness, ua rau muaj kev tiv thaiv rau thermal expansion thiab contraction.

6. Cov Plasters thiab Renders

HPMC yog qhov tseem ceeb hauv kev txhim kho kev ua tau zoo ntawm cov qauv plaster ib txwm muaj thiab niaj hnub.
Cov Kev Cuam Tshuam Tseem Ceeb:

• Tiv Thaiv Kev Qaug Zog: Muab kev tuav zoo heev rau ntawm cov chaw ntsug.
• Kev nplaum zoo dua: Ua rau kev sib txuas nrog cov substrates nce ntxiv.
• Kev Ua Haujlwm Tau: Tso cai rau kev nthuav dav thiab kev ua cov plasters yooj yim.

7. Pob zeb ua vaj tse

Txawm hais tias HPMC yog siv sparingly hauv cov qauv pob zeb, nws tuaj yeem txhim kho cov khoom tshwj xeeb.
Cov Kev Cuam Tshuam Tseem Ceeb:

• Kev Khaws Dej: Txo cov dej evaporation thaum lub sijhawm kho, txhim kho lub zog.
• Tiv Thaiv Kev Los Ntshav: Tiv thaiv kom dej tsis txhob sib cais ntawm qhov chaw.
• Pumpability: Ua kom cov dej ntws ntawm cov pob zeb hauv cov ntawv thov twj tso kua mis zoo dua.

8. Xim thiab Cov Tshuaj Pleev Xim

HPMC ua haujlwm ua cov khoom ua kom tuab thiab ruaj khov hauv cov txheej txheem kho kom zoo nkauj thiab tiv thaiv rau cov ntaub ntawv tsim kho.
Cov Kev Cuam Tshuam Tseem Ceeb:

• Kev Hloov Kho Rheology: Txhim kho cov dej ntws thiab cov khoom sib npaug.
• Kev Ruaj Ntseg: Tiv thaiv kev sib cais ntawm cov xim thiab cov khoom sau.
• Kev Tsim Yeeb Yam: Ua kom qhov tsos ntawm qhov chaw zoo nkauj thiab ua kom ruaj khov.

Cov txiaj ntsig ntawm kev siv HPMC hauv cov ntaub ntawv tsim kho

• Kev Ua Tau Zoo Dua: Txhim kho kev ua haujlwm, kev nplaum, thiab kev ua haujlwm ntev.
• Kev siv tau ntau yam: Haum rau ntau yam substrates thiab formulations.
• Cov txiaj ntsig kev lag luam: Txo cov khoom pov tseg thiab cov nqi zog ua haujlwm.
• Ib puag ncig-phooj ywg: Biodegradable thiab tsis muaj tshuaj lom, ua raws li cov qauv kev tsim kho kom ruaj khov.
