濟(jì)南專(zhuān)業(yè)防水http://www.7788qn.com/介紹說(shuō)卷材柔度即卷材低溫柔性是改性瀝青防水卷材的一個(gè)重要物理指標(biāo)。卷材柔度反映著卷材的內(nèi)在質(zhì)量和使用性能，了解卷材的柔度，掌握和運(yùn)用好卷材的柔度，對(duì)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(zhì)量具有重要意義。下面濟(jì)南天宇建防水的有關(guān)專(zhuān)家就給大家詳細(xì)介紹一下影響防水卷材柔度的因素。
1、濟(jì)南專(zhuān)業(yè)防水談到按試驗(yàn)方法規(guī)定，在測(cè)定卷材柔度前要將卷材的試樣在20±10℃的室內(nèi)放置至少24h，進(jìn)行測(cè)試的試件在試驗(yàn)前應(yīng)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(lái)就測(cè)。測(cè)定卷材柔度，要將卷材試件放置在規(guī)定溫度的冷凍液中保持1小時(shí)，保持時(shí)間的長(zhǎng)和短都會(huì)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(jì)南專(zhuān)業(yè)防水建議測(cè)定時(shí)要在卷材彎曲的部位放置一個(gè)圓棒，卷材要緊貼圓棒并圍繞圓棒彎曲180度，看是否出現(xiàn)裂紋，測(cè)柔度卷材試件要彎成弧形，折疊和彎成硬彎都是不對(duì)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(jì)南專(zhuān)業(yè)防水介紹說(shuō)測(cè)卷材柔度時(shí)，卷材彎曲的速度規(guī)定為3秒，即卷材從開(kāi)始彎曲至彎曲到180度結(jié)束，時(shí)間為3秒。彎曲速度越快，卷材越容易出現(xiàn)裂紋。反之，彎曲速度越慢，越不容易出現(xiàn)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(jì)南專(zhuān)業(yè)防水http://www.7788qn.com/提醒大家卷材柔度隨存放時(shí)間的延長(zhǎng)會(huì)發(fā)生變化，存放的時(shí)間越長(zhǎng)，卷材的柔度變化越大。據(jù)實(shí)際檢測(cè)，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(fā)生在卷材生產(chǎn)出來(lái)的前幾個(gè)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.
