If the color steel plate has been used for about ten years, some parts have rusted and leaked. The acid-base corrosion of industrial emissions will produce slight corrosion and leakage, which will seriously cause the whole color steel tile to fall off and affect the normal work. The service life of color steel tile is shortened. If you change the color steel plate after wearing rust, it will not only affect your normal production, but also the price is very expensive.

彩钢瓦屋面易渗漏的部位应进行系统的防水处理，主要是彩钢瓦的螺孔、彩钢瓦的搭接缝、彩钢瓦的屋面接缝、天沟的檐口。

Systematic waterproof treatment shall be carried out for the parts of the roof surface of color steel tile that are easy to leak, mainly including the screw hole of color steel tile, the lap joint of color steel tile, the roof joint of color steel tile, and the cornice of gutter.

彩钢板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，大风和暴雨导致彩钢板屋面长期震动。铁片的钉孔和接头会长期磨损，导致橡胶垫损坏，造成严重漏水。

The color steel roof has been damaged by environment and climate for a long time. The temperature difference of climate leads to shrinkage and deformation of color steel tile. In addition, strong wind and rainstorm caused long-term vibration of color steel plate roof. The nail hole and joint of iron sheet will be worn for a long time, resulting in damage of rubber pad and serious water leakage.

有的屋顶跨度大，人踩久了会造成中间积水，中间重力加大。雨越大，屋顶变形越严重。有些屋顶是由矿棉制成的，它有一个吸水的作用。

Some roof span, people stepped on for a long time will cause water in the middle, the middle of gravity increase. The bigger the rain, the more serious the roof deformation. Some roofs are made of mineral wool, which can absorb water.

在雨天，所有从屋顶泄漏的雨水都会聚在矿棉中，这将增加重量，甚导致屋顶坍塌。女儿墙高低跨屋面转角处渗水。初始防水施工用水泥抹八字角，防水保护用密封胶或防水涂料。水泥不与金属结合，容易产生裂缝，密封胶或涂料延伸率小，也会产生大裂缝。

On rainy days, all the rainwater leaking from the roof will gather in the mineral wool, which will increase the weight and even cause the roof to collapse. There is water seepage at the corner of high and low span roof of parapet. The initial waterproof construction uses cement to wipe the octagonal angle, and the waterproof protection uses sealant or waterproof coating. Cement is not combined with metal, easy to produce cracks, sealant or coating elongation is small, also can produce large cracks.

较容易也是难处理的就是“天沟防水”。非专职人士很难找到本质泄漏点。由于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，所以需要剪掉彩钢板多余的檐口来包裹整个天沟。

Easier and more difficult to deal with is "gutter waterproof". It is difficult for non professionals to find the essential leak. Because the design size and width of the gutter are not the same, the construction difficulty is not the same, some are too narrow, so it is necessary to cut off the extra cornice of the color steel plate to wrap the whole gutter.

排水沟漏水一般有两个方面。一是天沟设计不合理，淤泥堆积太厚，排水不及时，残留的积水长期浸泡，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，就不会被磨损。看完以上的内容，如果你对产品还有其它疑问，欢迎联系我们，我们期待与您达成合作。

Generally, there are two aspects to the leakage of drainage ditch. First, the design of the gutter is unreasonable, the silt accumulation is too thick, the drainage is not timely, and the residual water is soaked for a long time, resulting in the leakage of the gutter. 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 be discharged in time, so it will not be worn.
