搭接方式对高分子湿铺防水卷材防水可靠性的影响

Influence of overlap methods on waterproof reliability of polymer wet installed waterproof sheets

通过模拟高分子湿铺防水卷材施工时采用的湿铺搭接(S)和自粘搭接(Z)2种方法,对搭接边进行卷材-卷材剪切强度、卷材-卷材剥离强度及抗窜水性试验,比较2种搭接方式对高分子湿铺防水卷材防水可靠性的影响。结果表明,当卷材采用Z或者S搭接方式时,卷材的剪切强度、剥离强度及抗窜水性均能满足应用要求,且试验结果未见明显差异。

Through testing the shear strength,peel strength and. water channeling prevention of polymer wet installed waterproof sheets by simulating the overlap methods when applied self-adhering（Z） and wet installed （S）. The influence of Z and S on waterproof reliability of waterproof sheets is compared in this article. The results show that when adopting the overlap of Z and S,the shear strength,peel strength and water channeling prevention of waterproof sheets can meet the application requirements,and the results did not see obvious difference.
