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 kev deformation lossis tawg nyob rau hauv cov khoom sab nraud.
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 qis qhov xav tau kev saib xyuas 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, cracking, los yog 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.
