如果彩钢瓦用的时间久了，有些地方已经生锈漏水了。工业排放的酸碱腐蚀会产生轻微的腐蚀和泄漏，严重时会造成整个彩钢瓦脱落，影响正常工作。彩钢瓦使用寿命缩短。如果穿锈后换了彩钢瓦，不仅影响你的正常生产，还会很贵。

If the colored steel tile has been used for a long time, some places have rusted and leaked. The acid and alkali corrosion from industrial discharge will cause slight corrosion and leakage, and in serious cases, the whole color steel tile will fall off, affecting the normal operation. The service life of color steel tile is shortened. If you change the colored steel tile after wearing rust, it will not only affect your normal production, but also be very expensive.

彩钢瓦屋面的渗漏部位应进行系统防水，主要包括彩钢瓦的螺孔、彩钢瓦的搭接、彩钢瓦的屋面接缝和天沟的檐口。

The leakage part of the color steel tile roof shall be subject to systematic waterproofing, mainly including the screw hole of the color steel tile, the overlap of the color steel tile, the roof joint of the color steel tile and the cornice of the gutter.

彩钢屋面长期以来被环境和气候破坏。气候的温差导致彩钢瓦收缩变形。此外，强风和暴雨导致彩钢屋顶长期振动。铁皮的钉孔和接头会长期磨损，导致橡胶垫损坏，漏水严重。

Color steel roof has been damaged by environment and climate for a long time. The temperature difference of the climate causes the shrinkage and deformation of the colored steel tile. In addition, strong wind and rainstorm lead to long-term vibration of color steel roof. The nail holes and joints of the iron sheet will be worn for a long time, resulting in damage to the rubber pad and serious water leakage.

济南彩钢瓦厂发现，有些屋顶跨度大，中间会积水，中间会增加重力。雨越大，屋顶变形越严重。有些屋顶是用矿棉做的，能吸水。

Jinan Color Steel Tile Factory found that some roofs have a large span, and water will accumulate in the middle and gravity will increase in the middle. The more the rain, the more serious the roof deformation. Some roofs are made of mineral wool and can absorb water.

下雨天，所有从屋顶漏下的雨水都会聚集在矿棉里，增加重量，甚导致屋顶坍塌。女儿墙高低跨屋面转角处渗水。初次防水施工时，应用水泥抹平八字角，并用密封胶或防水涂料进行防水保护。水泥不与金属结合，容易产生裂缝，密封胶或涂料延伸率小，也会产生较大的裂缝。

In rainy days, all the rainwater leaked from the roof will gather in the mineral wool, increase the weight, and even cause the roof to collapse. Water seepage at the corners of the parapet high and low span roof. During the initial waterproof construction, cement shall be used to smooth the splay corners, and sealant or waterproof coating shall be used for waterproof protection. The cement is not combined with metal, which is easy to produce cracks. The small elongation of sealant or coating will also produce large cracks.

处理“天沟防水”是容易的，也是困难的，很难找到本质的漏点。因为天沟的设计尺寸和宽度不一样，施工难度也不一样，有的太窄了，需要剪掉多余的彩钢瓦檐口，把整个天沟包裹起来。

It is easy and difficult to deal with "gutter waterproofing", and it is difficult to find the essential leakage point. Because the design size and width of the gutter are different, the construction difficulty is also different, and some are too narrow. It is necessary to cut off the redundant colored steel tile cornice and wrap the entire gutter.

排水管渗漏一般有两个方面。一是天沟设计不合理，淤泥堆积太厚，排水不及时，残留积水长期浸泡，导致天沟漏水。只要每年按时定期对天沟进行清洗和冲洗，天沟内就不会有过多的灰层堆积，雨水也能及时排出，不会磨损。更多相关内容就来我们网站http://www.jnjgcg.com咨询！

There are generally two aspects of drainage pipe leakage. First, the gutter design is unreasonable, the sludge accumulation is too thick, the drainage is not timely, and the residual water is soaked for a long time, resulting in the gutter leakage. As long as the gutter is cleaned and washed regularly every year, there will not be too much ash accumulation in the gutter, and the rainwater can also be drained in time without wear.
