     对于防水工程的施工人员来说，他们经常会听到防水卷材或防水涂料。虽然他们每天都受到影响，但你真的知道他们之间的区别吗？[雷邦石]比较了两者的综合x能，使防水工人在今后选材时能够根据需要准确选材；

    （1） 防水卷材

    防水卷材主要用于建筑墙体、屋面、隧道、公路、垃圾填埋场等场所。它是一种柔x建筑材料产品，可卷曲成卷，以抵抗外部雨水和地下水的泄漏。作为工程基础与建筑物之间的无泄漏连接，

     it is the first waterproof barrier of the whole project ad plays a vital role i the whole project. The mai products are asphalt waterproof coiled material ad polymer waterproof coiled material.

    1. Advatages of waterproof coiled material:

    It has the advatages of coveiet costructio, short costructio period, o maiteace after formig, o ifluece of air temperature, small evirometal pollutio, easy to master the layer thickess accordig to the desig requiremets, accurate material calculatio, coveiet costructio site maagemet, ot easy to cut corers, uiform layer thickess,并能有效克服空铺时基层的应力（基层出现较大裂缝时可保持防水层的完整x）；

    2.防水卷材x能：

    （1） 耐水x

    耐水x是指在水的作用下，经水浸泡后，其x能基本不变。在压力水的作用下是不透水的。通常用抗渗x、吸水率等指标来表示。

    （2） 温度稳定x

    温度稳定x是指高温下不流动、不起泡、不滑动、低温下不脆化的x能，即，

     the ability to maitai the origial performace uder a certai temperature chage. It is commoly expressed by heat resistace, heat resistace ad other idicators.

    (3) Mechaical stregth, elogatio ad fracture resistace

    It refers to the performace that the waterproof coiled material bears certai load, stress or does ot break uder certai deformatio coditios. It is usually expressed by idexes such as tesile force, tesile stregth ad elogatio at break.

    (4) Flexibility

    Flexibility refers to the ability to maitai flexibility at low temperatures. It is very importat to esure easy costructio ad o embrittlemet. It is usually expressed by flexibility, low temperature bedig ad other idicators.（5） 大气稳定x

    大气稳定x是指在阳光、热量、臭氧等化学侵蚀介质的长期综合作用下，抵抗侵蚀的能力。通常用耐老化x、热老化保持率等指标来表示。
