在卷材防水層中粘結(jié)不實(shí)的部位，窩有水分和氣體，當(dāng)其受到太陽(yáng)照射或人工熱源影響后，體積膨脹，造成鼓泡。 如果僅有一層不明顯的白色小霧，說明保溫層基本干燥，可以準(zhǔn)備進(jìn)行防水層的施工。測(cè)試完畢應(yīng)注意將圓孔補(bǔ)平。采取這種測(cè)試方法，可以使施工人員比較準(zhǔn)確地掌握保溫層的干燥程度，以便及時(shí)安排防水層的施上。測(cè)試的時(shí)間宜選樣在下午2—3點(diǎn)鐘，此時(shí)保溫定溫度高，相對(duì)溫差人，測(cè)試的結(jié)果明顯、準(zhǔn)確，對(duì)大面積屋面保溫層應(yīng)多測(cè)試幾點(diǎn)，全面綜合其檢測(cè)數(shù)據(jù)，以提高其測(cè)試的準(zhǔn)確性。
1、直徑100mm以下的中、小鼓泡可用抽氣灌膠法治理，并壓上幾塊磚，幾天后再將磚移去即成。
100mm diameter or less, and small bubbling available plastic irrigation pumping method of governance, and pressed a few bricks, a few days before the bricks removed Serve.
2、直徑100～300mm的鼓泡可先鏟除鼓泡處的保護(hù)層，再用刀將鼓泡按斜十字形割開，放出鼓泡內(nèi)氣體，擦干水分，清除舊膠結(jié)料，用噴燈把卷材內(nèi)部吹干。隨后按順序把舊卷材分片重新粘貼好，再新貼一塊方形卷材（其邊長(zhǎng)比開刀范圍100mm），壓入卷材下，最后粘貼覆蓋好卷材，四邊搭接好，并重做保護(hù)層。上述分片鋪貼順序是按屋面流水方向先下再左右后上。
Bubbling 100 ~ 300mm diameter may be bubbling at the eradication of the protective layer, and then a knife bubbling by oblique cross cut, release the bubbling gas, dry water, remove the old binder with a blowtorch to roll interior dry. Then in order to re-paste the old membrane fragments good, and then posted a new square coil (which side is larger than the surgery range 100mm), under the pressure of the membrane, and finally paste membrane covering the good, good lap four sides, both as a protective layer. Paving the above sequence is fragmented by roofing direction before you get on the water and then left.
3、直徑更大的鼓泡用割補(bǔ)法治理。先用刀把鼓泡卷材割除，按上一做法進(jìn)行基層清理，再用噴燈烘烤舊卷材槎口，并分層剝開，除去舊膠結(jié)料后，依次粘貼好舊卷材，上鋪一層新卷材（四周與舊卷材搭接不小于100mm），然后貼上舊卷材。再依次粘貼舊卷材，上面覆蓋第二層新卷材，最后粘貼卷材，周邊壓實(shí)刮平，重做保護(hù)層。
Larger diameter bubbling with cut and fill method of governance. A knife to cut off the first bubble membrane, a practice carried out by the primary clean-up, and then blowtorch baking sheet Croucher old port and layered peel, remove the old binder, and then click Paste good old roll, capped a the new membrane layers (four weeks old sheet lap of not less than 100mm), and then paste the old membrane. Then followed paste the old membrane, covering the top of the second layer of the new membrane, and finally paste membrane surrounding compacted Calibrating, redo protective layer.
