摘要

PVC flooring systems exposed to humid and alkaline conditions have been studied during extended periods of time both in the field and in the laboratory. Moisture barriers of conventional thickness did not restrain moisture penetration. However, alkali resistant materials could serve as alkali barriers and protect the adhesive layer and PVC flooring from degradation up to at least 1.5 years. Some moisture barriers were not alkali resistant and could not protect the upper layers from alkaline hydrolysis. An evident smell of octanol was observed and the flooring showed staining. Without moisture barrier, the glue was rapidly destroyed, and the floor showed staining and smelled of octanol.
