对三种不同厚度的氯丁橡胶,丁基橡胶,天然橡胶和聚氯乙烯塑料薄膜进行了测量,结果表明厚度对渗透率没有影响,这证明了材料结构的连续性。还表明弹性材料和聚合材料的湿度对材料的渗透率是有影响的。丁基橡胶,天然橡胶和聚氯乙烯薄膜随浸泡时间的增加,渗透率减小。一般在27℃浸泡一周就达到饱和 Three different thicknesses of neoprene, butyl rubber, natural rubber and PVC film were measured. The results show that thickness has no effect on permeability, which proves the continuity of the material structure. It has also been shown that the moisture content of the elastomeric and polymeric materials has an effect on the permeability of the material. The permeability of butyl rubber, natural rubber and polyvinyl chloride film decreases with immersion time. Generally soaked in a week at 27 ℃ to reach saturation
