With the development of the market economy, China's steel industry has developed rapidly in terms of quantity and quality, laying a solid foundation for other industries. The pattern of building materials dominated by bricks, tiles, ash and stone was changed, and steel-structured color-slab structure buildings appeared. The emergence of this building structure has led to the widespread adoption of power plant steam turbine plants, automobile manufacturing, aircraft manufacturing, large-scale factories, large-scale supermarkets, and logistics warehouses. The biggest advantage of this type of building structure is that the construction period is short, the basic requirements are low, the span can be large, the indoor space is large, and the use is convenient. However, there are certain problems. The main problems are: leakage at the roof, rivets, and joints, which affects the use. After research, testing and construction, Shandong Juxinda Steel Co., Ltd. has concluded a set of effective large-scale color steel roof roof seepage maintenance methods. good results. The specific method is as follows:

First, the water leakage repair method at the seam of the board:
1, small seam repair methods:
1After the seam, apply a 60mm wide waterproof 2000PA one-component waterproof glue at both ends of the seam. The seam is adjacent to 20mm without coating.
2 Non-woven fabric (or glass fiber cloth), pasted on the sun-coated 2000PA waterproof rubber.
3 Brush on the non-woven fabric or glass fiber cloth for 3 times. After painting, the width is 50mm wider than the previous one and the thickness is about 1.8mm. Brushing more than once
A coating is not sticky. Shandong Juxinda Steel Co., Ltd. specializes in production and sales: color steel plate, color coated plate, printing plate, color steel coil, color coated roll, printed color coated board. The manufacturer is located in Dianzi Industrial Park, Boxing County, Binzhou, Shandong.

2, the board joints larger maintenance methods:
1 can fill the seam with DM-600 sealer PU sealant
2 Apply 60mm wide sunlight 2000PA single-component waterproof glue at both ends of the seam, and the seam is adjacent to 20mm without coating.
3 non-woven or glass fiber cloth, pasted on the coated sun 2000PA waterproof glue.
4 Apply 3 times of Sunshine 2000PA one-component waterproof glue on the cloth. The time after painting is 50mm wider than the previous one, and the thickness is about 1.8mm.
It is thin in the middle and thick on both sides. The last time the coating is applied, the coating is not sticky. Shandong Juxinda Steel Co., Ltd. specializes in production and sales: color steel plate, color coated plate, printing plate, color steel coil, color coated roll, printed color coated board. The manufacturer is located in Dianzi Industrial Park, Boxing County, Binzhou, Shandong.

Second, the repair method of leakage at the rivet:
Apply Sunshine 2000PA one-component waterproof glue for 4 times, the thickness is about 1.5mm, the diameter is about 60mm, the next time the coating is applied, the coating is not sticky, and the diameter of the coating is Φ15mm. The middle is thick and thin.
