彩钢瓦屋面为什么需要翻新？济南彩钢瓦厂为您讲解下。

Why does the color steel tile roof need to be renovated? Jinan Color Steel Tile Factory will explain to you.

彩钢瓦厂房主要是钢结构建筑，屋顶防水是由彩钢瓦刚性自防水起作用，并且是以排水为主，防水为辅，屋面没有系统的防水层，当彩钢瓦受到温差伸缩形变和松动后，在风雨较大的天气时容易造成彩钢瓦渗漏，经常需要进行彩钢瓦屋面翻新。

The color steel tile workshop is mainly a steel structure building. The roof waterproofing is mainly performed by the rigid self waterproofing of the color steel tile, and is mainly drainage, supplemented by waterproofing. There is no systematic waterproof layer on the roof. When the color steel tile is subject to temperature difference expansion deformation and looseness, it is easy to cause the color steel tile to leak in windy and rainy weather. The color steel tile roof often needs to be renovated.

这种特殊的结构形式是造成彩钢瓦漏水的主要原因。而彩钢瓦生锈主要是紫外线对彩钢瓦表面的保护漆造成破坏，从而使彩钢瓦的金属部分与外界空气水分进行连接，产生化学氧化作用。

This special structure is the main reason for water leakage of color steel tiles. The rust of color steel tile is mainly caused by the damage of ultraviolet ray to the protective paint on the surface of color steel tile, so that the metal part of color steel tile can be connected with the external air moisture to produce chemical oxidation.

生锈长时间不处理，容易将彩钢瓦锈穿孔，也可能造成渗漏水。所以我们需要经常检查屋面，发现问题后，选择通过耐久型彩钢瓦翻新专用漆翻新处理，这样省钱又省事。

If the rust is not treated for a long time, it is easy to pierce the color steel tile rust, and may also cause water leakage. Therefore, we need to check the roof frequently. After finding problems, we choose to renovate the durable color steel tile with special paint, so as to save money and trouble.

彩钢瓦生锈是一个不容易发现的问题，需要有维护人员经常到屋面进行检查，保持半年一次的检查周期比较合理。

Rust of color steel tiles is not easy to find, and maintenance personnel should often go to the roof for inspection. It is reasonable to keep the inspection cycle of half a year.

彩钢瓦本身是有使用寿命的，不同质量的彩钢瓦出现生锈的时间不一样，同时受到当地环境影响也所不同，根据经验，国内大部分彩钢瓦在使用5-10年内容易出现生锈问题。一旦出现闪修或局部生锈时，我们应该尽早进行处理。

Color steel tiles have their own service life. The rusting time of color steel tiles of different quality is different, and the impact of local environment is also different. According to experience, most color steel tiles in China are prone to rusting within 5-10 years of use. In case of flash repair or partial rust, we should deal with it as soon as possible.

处理越早越容易，等到全部烤漆脱落，整个彩钢瓦锈黑，这时就只能更换彩钢瓦屋面，此时如果再想要进行彩钢瓦翻新施工已经毫无意义可言了，喷涂任何的彩钢瓦翻新专用漆也于事无补了。关注我们http://www.jnjgcg.com，了解更多！

The earlier the treatment is, the easier it will be. When all the paint falls off and the whole color steel tile is rusty black, then the color steel tile roof can only be replaced. At this time, if you want to carry out the color steel tile renovation construction again, it is meaningless. Spraying any special paint for color steel tile renovation will not help.
