4. Teem Sijhawm: Plastering mortar yuav tsum muaj lub sijhawm tswj xyuas uas tso cai rau lub sijhawm txaus rau daim ntawv thov, kev tswj xyuas, thiab ua tiav ua ntej lub mortar pib tawv. Lub sijhawm teeb tsa yuav tsum tsim nyog rau qhov kev xav tau ntawm qhov project, tso cai rau kev ua haujlwm tau zoo yam tsis muaj kev cuam tshuam qhov zoo ntawm qhov tiav.
5. Lub zog: Plastering mortar yuav tsum tsim kom muaj lub zog txaus tom qab teeb tsa thiab kho kom tiv taus cov kev ntxhov siab thiab cov khoom uas tau ntsib thaum lub sijhawm ua haujlwm. Lub mortar yuav tsum muaj lub zog txaus compressive los txhawb nws tus kheej qhov hnyav thiab tiv thaiv deformation los yog tawg nyob rau hauv sab nraud loads.
6. Durability: Plastering mortar yuav tsum ua kom ruaj khov thiab tiv taus kev puas tsuaj, huab cua, thiab ib puag ncig yam xws li ya raws, kub hloov pauv, thiab tshuaj lom neeg raug. Lub plaster ruaj khov ua kom muaj kev ua haujlwm ntev thiab txo qhov kev xav tau ntawm kev tu lossis kho.
7. Kev tuav dej: Plastering mortar yuav tsum khaws cov dej kom zoo thaum lub sijhawm teeb tsa thiab kho cov txheej txheem los txhawb dej ntawm cov ntaub ntawv cementitious thiab txhim kho kev sib raug zoo thiab kev sib raug zoo. Kev tuav dej kom raug zoo txhim kho kev ua haujlwm thiab txo qhov kev pheej hmoo ntawm shrinkage, tawg, lossis deg tsis xws luag.
8. Shrinkage Control: Plastering mortar yuav tsum muaj qhov me me thaum lub sij hawm ziab thiab kho kom tsis txhob muaj cov kab nrib pleb lossis qhov tsis zoo. Shrinkage tswj additives los yog cov tswv yim yuav siv tau los txo qhov shrinkage thiab xyuas kom meej ib tug du, uniform tiav.
9. Compatibility: Plastering mortar yuav tsum tau sib xws nrog cov substrate, cov ntaub ntawv tsim kho, thiab cov khoom tiav siv hauv qhov project. Compatibility ua kom zoo adhesion, daim ntawv cog lus lub zog, thiab kev ua haujlwm ntev ntawm plaster system.
10. Kev zoo nkauj: Plastering mortar yuav tsum ua kom du, zoo ib yam, thiab ua kom zoo nkauj tiav uas ua tau raws li tus qauv tsim thiab kev tsim vaj tsev ntawm qhov project. Lub mortar yuav tsum muaj peev xwm ua tau raws li qhov xav tau kev ntxhib los mos, xim, thiab qhov chaw tiav los txhim kho cov tsos ntawm phab ntsa lossis qab nthab.

Los ntawm kev ua tau raws li cov kev cai no, plastering mortar tuaj yeem muab qhov ruaj khov, txaus nyiam, thiab ua tiav zoo rau sab hauv thiab sab nrauv hauv vaj tse, kev lag luam, thiab kev tsim kho vaj tse. Cov neeg tsim khoom ua tib zoo tsim cov plastering mortars kom ntseeg tau tias lawv ua tau raws li cov qauv no thiab ua tau zoo nyob rau hauv ntau hom kev siv thiab ib puag ncig.
