What should I pay attention to when fixing the PC solar panel?

Today, the editor of Chaomei will share with you what precautions should be taken when fixing the PC Sunshine Board?

1. The diameter of the fixed nail head should be more than 1.5 times larger than the diameter of the screw handle, and waterproof adhesive should be applied. Do not directly press the nail head on the board surface to reduce pressure.

2. Do not tighten the screws too tightly, otherwise it may cause stress and local cracks on the board surface.

3. Waterproof adhesive cannot use PVC pads or asphalt based waterproof adhesive tapes; Sealant, neutral glass adhesive must be used, and acidic adhesive must not be used.

4. During the installation process, it is not allowed to fix both ends first and then the middle. One end should be fixed first and constructed in the same direction, otherwise it will cause concentration of intermediate stress and cause deformation or cracking of the product.

5. Due to the fact that the linear expansion coefficient of the solar panel is about 6 times larger than that of metal materials, it is necessary to drill holes on the panel before fixing them with self tapping screws, and the self tapping screws must be inserted in the middle of the holes.

6. Reserve expansion space.

7. If a layer of sunlight board is added below the wave board, metal strips must be added to the fixed position of the lower layer of sunlight board, otherwise the self weight of the sunlight board will cause the sunlight board to sag, leading to cracks in the sunlight board around the screws.
