铝塑板广告牌开胶了怎么修复
What tools are used to cut aluminum-plastic panels:
Select according to specific circumstances. 1. If the batch of aluminum-plastic panels is large, it can be cut to length and then cut with an electric saw. 2. When the aluminum-plastic panels are of different sizes and the quantity is small, you can use a wallpaper knife to cut them. 3. When the aluminum-plastic panel needs to be bent and cut, it needs to be cut with an edge trimmer and then cut with a wallpaper knife. 4. Use aluminum-plastic panels to make signboards, which need to be cut with an electric saw.
Aluminum-plastic is a new type of decorative material. It was introduced to China from Germany and has been used in China for decades. It is not only affordable, but also has good processing performance and is fire-proof and moisture-proof. Therefore, it is widely used in buildings. Exterior walls, renovation of old buildings, billboards and display racks are in progress.
How to choose an aluminum-plastic panel:
1. First of all, when choosing an aluminum-plastic panel, you should look at its flexibility. A good aluminum-plastic panel has strong flexibility. Pick up the plate and bend it. It is uniform and not easy to be damaged or broken. On the contrary, if the aluminum-plastic panel breaks easily with just a slight fold, it means it is of inferior quality.
2. Secondly, when purchasing aluminum-plastic panels, the merchant is required to provide product instructions and relevant qualification certificates. If the merchant cannot provide them, it means that the product quality needs to be studied. It is recommended to go to a regular brand store to buy. Not only the quality is assured, but also if you encounter problems later, there is no need to worry about the after-sales aspect.
3. Finally, when choosing an aluminum-plastic panel, you should look at its appearance. The surface of a good plate is smooth and smooth, without bulges, burrs and other defects, and the thickness also meets national standards. On the other hand, if the surface of the panel is rough and uneven, and the thickness is light and thin, it may be a low-quality panel, which will affect the quality of the later construction.
Lay out the wiring → fix the frame’s connector → fix the frame → install the aluminum plate → closing structure Process → Install advertising words → Inspection
1. Installation pre cautions
1. The variety, quality, color, pattern, and lines of the aluminum plate should meet the design requirements, and there should be a product certificate.
2. If the frame of the advertising sign adopts light steel keel, its specifications and shape should meet the design requirements, and rust removal and anti-rust treatment should be carried out.
3. When installing aluminum plates, when there are no design requirements, core-pulling aluminum rivets should be used, and rubber rings must be placed in the middle. The blind rivet spacing should be controlled within 100-150mm.
(1) Laying out the wires
Fix the skeleton and pop the position of the skeleton onto the base layer. The skeleton is fixed on the main structure, and the quality of the main structure is checked before laying out the wires.
(2) Connectors for fixing the skeleton
Weld the connectors on the columns of the main structure to fix the skeleton.
(3) Fixed skeleton
The skeleton has been treated with anti-corrosion treatment in advance. The installation frame is in accurate position and the combination is firm. After installation, check the centerline, surface elevation, etc. In order to ensure the installation accuracy of the board, it is advisable to use theodolite to penetrate the beams and mullion members. Properly handle deformation joints, settlement joints, variable cross-sections, etc. to ensure that they meet usage requirements.
(4) Installation of aluminum plates
The installation and fixation of aluminum plates must be firm, reliable, simple and easy.
1. The gap between the boards should be processed internally to make it flat and smooth.
2. After the aluminum plate is installed, cover and protect the parts easily contaminated with plastic film or other materials.
