彩钢瓦翻新施工大多采用底漆搭配面漆喷涂施工工艺。底漆是基面喷涂的层，环氧底漆用于提高基面附着力和防锈作用，增加面漆的丰满度、抗碱性、防腐性等。下面济南彩钢瓦厂来讲讲彩钢瓦翻新修缮技术与施工流程。

The renovation construction of color steel tile mostly adopts the construction process of primer and finish paint. The primer is the layer sprayed on the base surface. The epoxy primer is used to improve the adhesion and anti-rust effect of the base surface, and increase the fullness, alkali resistance, corrosion resistance, etc. of the finish paint. Next, Jinan Color Steel Tile Factory will talk about the renovation technology and construction process of color steel tiles.

彩钢瓦翻新修缮技术措施

Technical measures for renovation and repair of color steel tile

施工过程注意查漏补缺

Pay attention to check and fill in the gaps during construction

彩钢瓦打磨干净后，在进行局部找补有漏水地方。用金属加工胶补。

After the color steel tile is polished, make up the leaking part locally. Repair with metalworking adhesive.

施工环境温度

Construction ambient temperature

温度在5度-35度,相对湿度<85%,雨、雾、雪和灰尘条件下不可施工。

The construction can not be carried out under the conditions of rain, fog, snow and dust when the temperature is between 5 ℃ and 35 ℃ and the relative humidity is less than 85%.

重复涂刷

Repeated painting

施工时确保涂层完全均匀覆盖，有遗漏或者薄弱涂层需及时修补;对于重防腐施工建议12小时后再涂刷一道。

During construction, ensure that the coating is completely and evenly covered, and any missing or weak coating needs to be repaired in time; For heavy anti-corrosion construction, it is recommended to apply another coat after 12 hours.

彩钢瓦翻新施工流程

Construction process of color steel tile renovation

1、对屋面表面进行清理清洗，腐蚀生锈处进行轻微打磨除锈，打磨掉表面松动浮锈及其它杂质。

1. Clean and clean the roof surface, slightly polish the corroded and rusty parts to remove the loose rust and other impurities on the surface.

2、彩钢瓦屋面清理干净后，对屋面加固，在无松动、无粉尘、无明水时做以下防腐翻新处理。

2. After the color steel tile roof is cleaned, the roof shall be reinforced, and the following anti-corrosion renovation treatment shall be carried out when there is no looseness, dust or open water.

3、整个屋面喷涂带锈转化底漆--遍，按照厚锈多涂，薄锈少涂,凹凸不平部位重复施涂的原则，使锈层完全润透，并及时用绵纱流坠与淌。

3. The whole roof shall be sprayed with rust conversion primer for one time. The principle of applying more thick rust, less thin rust, and repeated application of uneven parts shall be followed to make the rust layer completely wet, and remove the sagging and flowing with cotton yarn in time.

4、喷涂完之后，铁锈在1~2h内将转化形成黑色或灰色的防锈膜层，如果局部厚锈部位出现红锈色未转变,表干之前再补涂，使其浸透。

4. After spraying, the rust will be converted into black or gray antirust film within 1~2h. If the red rust color does not change at the local thick rust part, it shall be re-coated before the surface is dry to make it saturated.

5、防锈膜层表干后，一般情况下2~4h即达成实干,即干透后直接进行面漆施工。在不赶工期的情况下，建议表干8h后进行油漆施工，此时防锈膜固化完全，达到高结合力。

5. After the surface of the antirust film is dry, it is generally dry within 2~4 hours, that is, the finish coat is directly applied after it is dry. Under the condition of not catching up with the construction period, it is recommended to carry out the paint construction after the surface is dried for 8 hours. At this time, the anti-rust film is fully solidified to achieve high adhesion.

在此厂家提醒您，操作人员要做好自身的防护，毕竟喷漆本身是化学品，要佩戴手套，身体也穿上一些保护的衣物，防止身上沾染喷漆。为重，希望您能理解，关注我们网站http://www.jnjgcg.com了解事项吧！

Here, the manufacturer reminds you that the operators should take good care of their own protection. After all, spray paint itself is a chemical, so they should wear gloves, and wear some protective clothing to prevent the body from being contaminated with spray paint. We hope you can understand and pay attention to our website http://www.jnjgcg.com Understand the matter!
