6. Qhov xwm txheej: plastering collter yuav tsum ua kom ruaj khov thiab tiv taus tsis zoo, huab cua, thiab ib puag ncig, ntsuas hluav taws xob, thiab tshuaj lom neeg raug tshuaj lom neeg. Lubricable plaster ua kom muaj kev ua tau ntev ntev thiab txo qis kev xav tau kev saib xyuas lossis kev kho vaj tse.
7. Dej khaws cia: Plastering coll yuav tsum tau khaws cov dej thiab cov txheej txheem kho kom txhawb nqa cov khoom siv thiab txhim kho txoj hlua khi. Cov dej kom zoo txhim kho kev ua haujlwm ua haujlwm thiab txo cov kev pheej hmoo ntawm shrinkage, tawg, lossis nto yam tsis xws luag.
8. Shrinkage tswj: plastering cug yuav tsum muaj kev sib tw tsawg kawg thaum ziab thiab kho kom tiv thaiv tau cov kab nrib pleb lossis kev ua tsis tiav. Shrinkage tswj addititives lossis cov tswv yim yuav siv tau los txo cov shrinkage thiab ua kom muaj kev ua kom tiav.
9. Kev sib xyaw ua tau: plastering coll yuav tsum tau tshaj nrog substrate, cov ntaub ntawv tsim kho, thiab cov ntaub ntawv tiav siv nyob rau hauv txoj haujlwm. Sib cav ua kom tiav cov adhesion tsim nyog, nyiaj txiag dag zog, thiab kev ua tau ntev ntawm lub plaster system.
