With the development of market economy, China's color steel plate has made great progress in all aspects, laying a solid foundation for other industries, but also brought great changes and convenience to people. Especially in the construction industry,
the pattern of building materials mainly consisting of bricks, tiles, lime and stone has been changed, and coloured steel plate structures have emerged. But there are also some shortcomings, such as color steel plate, the main problems are: roof,
rivet, plate seam leakage phenomenon, affecting the normal use. Through research, test and construction, some effective maintenance methods of large-scale color steel roof seepage are summarized by relevant experts. Maintenance methods for rainwater
leakage of color steel plate are as follows:
1. Rain Leakage Method of Coloured Steel Plate Joints:
1. Brush three times on non-woven or glass fiber cloth. The width and thickness of the second brush are 50 mm and 1.8 mm wider than that of the previous brush. The last coat is not sticky to the hand.
2. It can be coated with 60 mm sunshine 2000 PA single component waterproof glue at both ends of the seam, but not near the seam 20 mm.
3. Non-woven fabric, 150 mm wide, pasted on sunshine 2000 PA waterproof glue.
2. Maintenance method of water leakage at rivet: apply sunshine one-component waterproof glue to brush 4 times, the thickness is about 1.5mm, the diameter is about 50-60mm, the next time the coating is not sticky to the hand, and the diameter is bigger than that of the first time, showing the middle thickness and circumference thin. So the rivet won't leak.
Attention should be paid to some details. Coloured steel plate is generally not a big problem, so it is a better building material in building materials.
