VAP 膜透氣性測試及影響因素分析

打開文本圖片集

摘 要 研究測試了不同批次、不同型號單向透氣膜（VAP膜）的透氣性能，并利用掃描電鏡對VAP膜的微觀結(jié)構(gòu)進(jìn)行掃描分析，測試結(jié)果表明，VAP膜透氣性與其成型工藝相關(guān)，并且與涂層截面的孔隙相關(guān)，涂層截面孔隙率越高，透氣性越好；另外，透氣性與涂層表面孔洞數(shù)量無直接相關(guān)性。

關(guān)鍵詞 防水透氣膜；涂層；孔隙率；透氣性；濕法涂布

ABSTRACT The air permeability of different batches and different types of VAP membranes was tested， and the microstructure of VAP membranes was scanned and analyzed by scanning electron microscope， and the test results showed that the air permeability of VAP membrane was related to its molding process and the porosity of the coating section， and the higher the porosity of the coating section， the better the air permeability. It is worth mentioning that the air permeability is not directly related to the number of pores on the surface of the coating.
