防水补漏基本知识

水的特性
Characteristics of Water
水是无孔不入的，它借着风压、对流、冲击、附着、毛细等力量，逐渐渗入建筑内部，而且在渗透 的过程不易从表面发觉。换言之，找寻漏水原因必须深入“内脏”分析判断，才能对症下药。[1]
Water is all-pervasive, it gradually infiltrates into the interior of the building by means of wind pressure, convection, impact, adhesion, capillary and other forces, and the process of infiltration is not easy to detect from the surface. In other words, in order to find out the cause of water leakage, we must go deep into the "viscera" analysis and judgment, in order to suit the symptoms. [1]
压力变化
Pressure change
水一旦渗透到建筑物里面，在有限的空间内，等太阳一晒，产生热能，就形成水蒸气，这些水蒸气 产生大量的压力足以破坏原有的防水层，甚至于表面的装璜及饰材(譬如，油漆脱落、壁纸发黑、磁砖鼓 起、木质地板膨鼓)换句话说，一单位的水，如果全部变成水蒸气，在建筑物内部有限度的空间里面，就 产生了1240倍的压力，这个压力的破坏性实在太可怕了。(所以我们时常发现防水胶施工在含水的泡沫水 泥上，不久就整个鼓起剥落了
Once water penetrates into the building, in the limited space, when the sun shines, it generates heat energy, and forms water vapor, which produces a large amount of pressure enough to destroy the original waterproof layer, and even change the surface decoration and decorative materials (such as paint shedding, wallpaper blackening, magnetic brick bulging, wooden floor bulging). In other words, a unit of water, if it all turns into steam, produces 1240 times the pressure in the limited space inside the building. The destructive effect of this pressure is terrible. (so we often find that waterproofing glue is constructed on water containing foam cement, and it soon flake off.
