福州专业防水http://fzfangshui.hbugo.com/介绍说卷材柔度即卷材低温柔性是改性沥青防水卷材的一个重要物理指标。卷材柔度反映着卷材的内在质量和使用性能，了解卷材的柔度，掌握和运用好卷材的柔度，对做好改性沥青防水卷材的屋面施工、减少损失、杜绝渗漏、保证工程质量具有重要意义。下面福州天宇建防水的有关专家就给大家详细介绍一下影响防水卷材柔度的因素。
1、福州专业防水谈到按试验方法规定，在测定卷材柔度前要将卷材的试样在20±10的室内放置至少24h，进行测试的试件在试验前应在（23±2）的平板上放置至少4h，不能将热的卷材或冰冷的卷材直接拿来就测。测定卷材柔度，要将卷材试件放置在规定温度的冷冻液中保持1小时，保持时间的长和短都会影响卷材的柔度。
Jinan professional waterproof Speaking test methods specified by the sample to the indoor coil of 20 ± 10 for at least 24h before measuring membrane flexibility, for testing prior to the test specimen shall be (23 ± 2) place on a plate, at least 4h can not be cold roll coil or heat brought on directly measured. Determination of membrane flexibility, the specimen is placed in the coil to a predetermined temperature in the freezing solution for 1 hour, the compliance of long and short holding time will affect the web.
2、福州专业防水建议测定时要在卷材弯曲的部位放置一个圆棒，卷材要紧贴圆棒并围绕圆棒弯曲180度，看是否出现裂纹，测柔度卷材试件要弯成弧形，折叠和弯成硬弯都是不对的。
Jinan professional waterproof proposal when measured to be placed in the web site of a curved rod, coil should be close to the rod and the rod bent around 180 degrees to see if the cracks, measuring compliance membrane specimen to be bent into an arc folded and bent hard bend is wrong.
3、福州专业防水介绍说测卷材柔度时，卷材弯曲的速度规定为3秒，即卷材从开始弯曲至弯曲到180度结束，时间为3秒。弯曲速度越快，卷材越容易出现裂纹。反之，弯曲速度越慢，越不容易出现裂纹，卷材厚度不同，卷材的柔度就不一样。
Jinan professional waterproofing membrane, said the measure compliance, the roll bending speed prescribed for 3 seconds, the membrane begins to bend to 180 degrees bent over, time is 3 seconds. Bending faster, more prone to cracking coil. Conversely, bending slower, less likely to crack, different membrane thickness, softness is not the same membrane.
4、福州专业防水http://fzfangshui.hbugo.com/提醒大家卷材柔度随存放时间的福州会发生变化，存放的时间越长，卷材的柔度变化越大。据实际检测，卷材的柔度在1年中一般要下降5左右，卷材柔度降低通常发生在卷材生产出来的前几个月。
Jinan professional waterproofing membrane flexibility to remind everyone with storage time will change, the longer the storage time, the greater the change in membrane flexibility. According to the actual testing, compliance coil in a
year generally fall about 5 , coil softness reduce membrane production usually occurs in the first few months out.
