沥青油毡防水层只能与干燥、洁净的基层产生理想的粘结。积水的或有水珠的潮湿基层表面不仅不能与卷材防水层产生良好的粘结,而且由于施工过程中常把水分或潮气带入各层卷材和沥青之间,使整个卷材防水层遭到破坏。因此如何为地下卷材防水层的施工创造一个即使是暂时相对干燥、洁净的基层条件,对整个地下卷材防水层来说是一个关键性问题。 Bituminous tarpaulin waterproof layer can only produce ideal bonding with dry, clean base layer. The surface of a watery or beaded wet base not only fails to produce a good bond with the coil waterproof layer, but also often causes moisture or moisture into the space between the coils and the bitumen during the construction process, making the entire coil waterproof layer. been destroyed. Therefore, how to create a base condition that is even relatively dry and clean for the construction of the waterproofing layer of the underground coil is a key issue for the entire waterproof layer of the underground coil.
