关于防水补漏知识，很多都不甚了解，今天我们来深入研究下，防水补漏相关知识点:
A waterproof knowledge, many of them do not know, today we study, waterproof related knowledge:
1 水与水蒸气的压力变化： 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)这中间的变化是：1 mole的水18g 体积为18㏄；1 mole的水蒸气，体积为22.4升＝22400㏄。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，不久就整个鼓起包了。
The 1 water and water vapor pressure change: once the water penetration into the building, in a limited space, such as the sun, heat, the formation of water vapor, the water vapor generated a lot of pressure is enough to destroy the original waterproof layer, even surface decoration and decorative material (for example, peeling paint, wallpaper black tile, wood flooring, with bentonite drum) is in the middle of this change: 1 mole 18G water volume is 18; 1 mole water vapor, volume of 22.4 liters = 22400. In other words, if a unit of water is completely vapour and has a limited space inside the building, it will generate 1240 times of pressure. The destructive force of this unit is really terrible. So we often find waterproof glue built on water - bearing foam cement, and soon it's all wrapped up.
2 水的特性： 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，才能对症下药。
2, the characteristic of water is that water is pervasive. It penetrated into the interior of buildings by means of wind pressure, convection, impact, attachment, capillary and other forces, and the process of infiltration is not easy to detect from the surface. In other words, to find out the cause of water leakage must be deep "viscera" analysis, in order to remedy the problem.
3 防水必须做在坚实的躯体上面： 与防水材料接着的界面必须不可有膨鼓、起沙、蜂巢、木头、纸屑、污泥、小石块、也不能做在松动不牢固的表体上，原因是附着性不良，再加上太阳紫外线破坏，建筑物本身热涨冷缩，以及水蒸气压力破坏，容易造成防水层老化、失败。
3 waterproof must be made in solid body and waterproof material must be above: then the interface can not have expansion drum, sand, wood, paper, honeycomb, sludge, small stones, can not do in the loose loose body, the reason is attached to adverse, coupled with the solar ultraviolet radiation damage, the building itself thermal expansion and contraction, and the water vapor pressure is likely to cause damage, aging, failure of waterproof layer.
4围堵式的防水容易失败： 防水应该从根源治起，用围堵方法，水是无孔不入，也会产生压力破坏，根源不治焉能持久，举例来说：顶楼漏水的位置，刚好在加盖违建房间里面，一般人就想要从外围
The 4 type of waterproof containment: Waterproof should be prone to failure from the root of the problem. With the method of containment, the water will produce pressure get in by every opening, destruction, root treatment can lasting, for example: the top Water Leakage position, just stamped illegally built room, ordinary people want from the periphery
5 正面防水优于负面防水： 如屋顶防水，直接做在屋顶表面，墙壁防水应直接做在外墙、水箱漏水直接做在水箱内层、浴室渗水就要将浴缸、磁砖打除，重新做防水，为什么呢？水有压力会往他处扩散，房子里死角的地方也不容易施工。这里所讲的"优于"是相对比较的，而非绝对性的。因为随着科技的发达，市面上陆续有人推出负面施工的防水材料───抗负水压的硅酸质系列渗透性粉末，以及高低压注入合成树脂产生膨胀结晶体，亦可防水，但是并非所有的场合都可成功的施工，所以非不得己，应该采正面防水施工。
5 is better than negative: such as waterproof waterproof waterproof roof, directly on the surface of the roof, the wall waterproof should be directly on the wall, water in the water tank, the inner Water Leakage directly to the bathtub and bathroom seepage tile play in, re do the waterproofing, why? Water pressure will spread to him, and the corner of the house is not easy to build. The "superior" here is relative, not absolute. Because with the development of science and technology, there have been launched construction waterproof material negative -- anti negative pressure silicate series permeability and expansion of crystal powder, synthetic resin, high and low pressure injection can also be waterproof construction, but not all situations can be successful, so not himself, should take positive construction waterproof.
