防水补漏的四点基本知识介绍!

 文章来源:http://www.jnldfs.com/ 发布时间:2021-09-30   

在我们的日常生活中如果家里要防水补漏的话,这可是一个非常令人烦燥的问题,在这里普及防水补漏的四点基本知识。
In our daily life, it is a very annoying problem if we want to waterproof and repair leaks at home. Here we popularize the four basic knowledge of waterproof and repair leaks.
基本知识一,水的特性,我们知道水是无孔不入的,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。
Basic knowledge 1: the characteristics of water. We know that water is pervasive. It gradually infiltrates into the interior of the building through wind pressure, convection, impact, adhesion, capillary and other forces, and it is not easy to find from the surface in the process of infiltration. In other words, to find the cause of water leakage, we must go deep into the "internal organs" to analyze and judge, so as to suit the remedy to the case.
基本知识二,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)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。
Basic knowledge 2: the pressure change of water and steam. Once water penetrates into the building and generates heat energy in a limited space, it will form steam. These steam generate a large amount of pressure, which is enough to destroy the original waterproof layer, and even the decoration and decoration materials on the surface (for example, paint falling off, wallpaper blackening, tile bulging, wooden floor bulging) In other words, if a unit of water turns into steam, it will produce 1240 times the pressure in the limited space inside the building. The destructiveness of this pressure is terrible.
基本知识三,基层要求,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。
Basic knowledge 3. The base course requires that the interface with the waterproof material must be free from swelling, sand, honeycomb, wood, paper scraps, sludge and small stones, and cannot be made on the loose and unstable table body. The reason is poor adhesion, coupled with the damage of solar ultraviolet rays, the heat rise and cold contraction of the building itself, and the damage of water vapor pressure, which is easy to cause the aging of the waterproof layer Failed.
基本知识四,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,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,而非性的。因为随着科技的发达,市面上陆续有人推出背水面施工的防水材料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,所以非不得已,应该采正面防水施工。
Basic knowledge 4. Positive waterproofing is better than negative waterproofing. For example, roof waterproofing should be done directly on the roof surface, wall waterproofing should be done directly on the outer wall, water leakage in the water tank should be done directly on the inner layer of the water tank, water pressure will spread to other places, and it is not easy to construct in dead corners of the house. The "superior" mentioned here is relatively comparative, not sexual. With the development of science and technology, waterproof materials for back surface construction and expanded crystals produced by high and low pressure injection of synthetic resin are successively introduced in the market, which can also be waterproof. However, not all occasions can be successfully constructed, so it is necessary to adopt front waterproof construction.
