濟南專業防水http://m.1222777.com/介紹說卷材柔度即卷材低溫柔性是改性瀝青防水卷材的一個重要物理指標。卷材柔度反映著卷材的內在質量和使用性能，了解卷材的柔度，掌握和運用好卷材的柔度，對做好改性瀝青防水卷材的屋面施工、減少損失、杜絕滲漏、保證工程質量具有重要意義。下面濟南天宇建防水的有關專家就給大家詳細介紹一下影響防水卷材柔度的因素。
1、濟南專業防水談到按試驗方法規定，在測定卷材柔度前要將卷材的試樣在20±10℃的室內放置至少24h，進行測試的試件在試驗前應在（23±2）℃的平板上放置至少4h，不能將熱的卷材或冰冷的卷材直接拿來就測。測定卷材柔度，要將卷材試件放置在規定溫度的冷凍液中保持1小時，保持時間的長和短都會影響卷材的柔度。
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、濟南專業防水建議測定時要在卷材彎曲的部位放置一個圓棒，卷材要緊貼圓棒并圍繞圓棒彎曲180度，看是否出現裂紋，測柔度卷材試件要彎成弧形，折疊和彎成硬彎都是不對的。
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、濟南專業防水介紹說測卷材柔度時，卷材彎曲的速度規定為3秒，即卷材從開始彎曲至彎曲到180度結束，時間為3秒。彎曲速度越快，卷材越容易出現裂紋。反之，彎曲速度越慢，越不容易出現裂紋，卷材厚度不同，卷材的柔度就不一樣。
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、濟南專業防水http://m.1222777.com/提醒大家卷材柔度隨存放時間的延長會發生變化，存放的時間越長，卷材的柔度變化越大。據實際檢測，卷材的柔度在1年中一般要下降5℃左右，卷材柔度降低通常發生在卷材生產出來的前幾個月。
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.
