彩钢瓦不同生锈情况如何翻新处理

彩钢瓦锈蚀一般分为轻度锈蚀彩钢瓦、轻度中度锈蚀彩钢瓦、较严重锈蚀彩钢瓦。根据不同的锈蚀情况，处理方法也不同。我国工业兴起以来，钢结构厂房遍布全国，每年不断增加。钢结构厂房屋顶、墙面彩钢瓦因风、日、酸雨、化学污染等不同因素老化生锈，加之彩钢瓦市场混乱，质量参差不齐，有的厂家为了节约成本，使用劣质烤漆，而原漆膜的耐候性和耐腐蚀性能较差，导致使用寿命下降。

1.轻度锈蚀的 彩钢瓦：轻度锈蚀的彩钢瓦平屋顶较易翻新。人们只需遵循上述生产流程，即可正常操作。由于轻微锈蚀，可立即选用1-2倍的防腐涂料进行涂装，具有很好的防腐效果，此外，还可合理降低装修成本。
2.彩钢瓦有轻度到中度腐蚀：这种情况比较常见。彩钢瓦屋面锈蚀，但尚未达到渗水程度。因此，人们只需进行一切正常的装修。标准施工步骤为打磨、除灰、1-2遍防锈处理面漆、1-2遍面漆。
3、锈蚀严重的彩钢瓦：锈蚀严重的彩钢瓦翻新成本很高。除腐蚀问题外，部分部位还会出现渗水和砂眼。这种修理必须进行。工程施工工艺同打磨、除灰、防水、封堵，面漆两道，油漆两道

Colr steel tile rust is generally divided into slight corrosion color steel tile, light moderate corrosion color steel tile, more serious corrosion color steel tile. According to different rust situation, the disposal method is different. Since the rise of China's industry, steel structure workshops are all over the country, increasing continuously every year. The colored steel tiles on the roof and wall of steel structure workshops are aged and rusted due to different factors such as wind, sun, acid rain, chemical pollution, etc. In addition, the market of color steel tile is chaotic, the quality is different, some manufacturers use inferior baking paint to save cost, and the original paint film has low weatherability and anti-corrosion performance, which leads to the decline of service life.

1. Slightly rusted color steel tile: it is relatively easy to renovate the slightly rusted color steel tile flat roof. People only have to follow the above production process and operate normally. Because it is slightly rusted, they can immediately select 1-2 times of anti-corrosion paint for painting, which can have very good anti-corrosion effect, In addition, it can reasonably reduce the renovation cost.
2. Color steel tile with mild to moderate corrosion: this situation is more common. The roof of color steel tile is corroded, but it has not reached the degree of water seepage. Therefore, people only have to carry out all normal renovation. The standard construction steps are polishing, ash removal, 1-2 times of antirust treatment topcoat, 1-2 times of surface paint.
3. Color steel tile with serious corrosion: the renovation cost of color steel tile with serious corrosion is very high. In addition to the problem of corrosion, there will still be water seepage and sand holes in some parts. This kind of repair must be carried out. The engineering construction process is the same as polishing, ash removal, waterproof and plugging, two coats of topcoat and two coats of paint.
