Plaster retarders pab txo cov kev cuam tshuam ntawm ib puag ncig cov teeb meem no los ntawm kev muab kev tswj hwm ntau dua ntawm cov txheej txheem teeb tsa.

plaster retarder yog ib qho tseem ceeb ntxiv rau hauv daim ntaub ntawv plastering, muab lub sijhawm ua haujlwm ntev, nce kev tswj, thiab txo cov khib nyiab.
