How to attach aluminum-plastic panels to billboards with arcs

If it is bent at 90 degrees, you need to use an edge trimmer to break the inner layer of the double-sided plastic aluminum panel (the relatively thin side of the aluminum film) to the black plastic layer in the middle About half the thickness, then place the broken part on the straight edge, and slowly bend it from the intact side to the broken side to 90 degrees. The 90° bent plastic aluminum plate should be 4° thick, and the thickness of the aluminum film should not be less than 15S, otherwise it will easily wrinkle and break when folded. If it is not a 90-degree bend, there are two ways. The simple method requires first processing a cylinder with the same radius as the required radius, then fixing one edge of the plastic aluminum plate on the cylinder, and then slowly pre ssing the plastic aluminum plate toward the cylinder along the fixed edge outward until the plastic aluminum plate is The arc meets the requirements; then the more formal method is to process the arc on the pre ssing machine. The quality of processing by pre ssing machine is better

(4) Panels, sign boards and display racks.

(5) Interior wall decorative panels, ceilings, and billboards.

(6) Industrial materials and refrigerated truck bodies.

(7) Air conditioners, televisions and other household appliances.

2. Use of aluminum gussets: Aluminum gussets are widely used in outdoor curtain wall decoration, indoor high-end home decoration, advertising decoration, etc. because of their many colors, strong decorative properties, and good weather resistance.

2. Different characteristics

1. Characteristics of aluminum-plastic panels:

(1) Super peelability

Aluminum-plastic panels adopt A new process has been developed to improve the peel strength, a key technical indicator of aluminum-plastic composite panels, to an excellent state, and accordingly improve the flatness and weather resistance of aluminum-plastic composite panels.

(2) The material is easy to process

Aluminum-plastic panels weigh only about 3.5-5.5 kilograms per square meter, which can reduce damage caused by earthquake disasters and are easy to operate. Its superior construction capabilities can use simple woodworking tools to complete cutting, cutting, edge shaping, bending into arcs, right angles and other shapes, and can cooperate with designers to make various changes. Installation is simple and quick, reducing construction costs.

(3) Excellent fire resistance

The middle of the aluminum-plastic panel is a polyethylene plastic core of flame-retardant material, and the aluminum layers on both sides are extremely difficult to burn. Therefore, it is a safe fire-resistant material that meets the fire protection requirements of building regulations.

2. Features of aluminum gusset plates:

(1) Excellent plate surface coating performance. High-quality aluminum alloy fasteners generally use high-quality paint and are painted using imported automatic high-speed coating lines. The surface of the board is flat and uncoated.

Fluorocarbon coated board is an ideal decorative material for outdoor use. The service life is more than 20 years and it is easy to maintain. It can resist the erosion of acid, alkali and salt spray for a long time and does not change color. Fluorocarbon coated panels are cleaned with water and look like new.

(2) Extremely strong composite fastness. High-quality aluminum gussets are made of polymer plastic and polymer materials by hot pre ssing. Under normal circumstances, after a 2-hour boiling water test, there is no damage to the bonding layer.

(3) Strong temperature adaptability. Aluminum gussets can generally be used under large temperature changes without affecting their excellent performance.

(4) Light weight and high strength. Generally speaking, the average weight of each board is about 8.5 kg. At the same stiffness, the weight is much lighter than other materials.

Extended information:

Aluminum-plastic panels are composed of multiple layers of materials. The upper and lower layers are high-purity aluminum alloy plates. It is a non-toxic low-density polyethylene (PE) core board with a protective film on the front. The front of the outdoor aluminum-plastic panels uses fluorocarbon resin (PVDF) paint, and the front of the indoor aluminum-plastic panels uses non-fluorocarbon resin paint.

Since the aluminum-plastic panel is made up of two layers of inner and outer aluminum plates sandwiched between LDPE sheets, it is strictly prohibited to damage the aluminum-plastic panel that is directly exposed to the atmosphere without decoration or sealing during use. Cut the edges or machined holes, otherwise it will cause cracking of the aluminum plate and composite layer. In order to save materials, some construction units often use aluminum-plastic panels for direct decoration without decoration, causing unimaginable serious consequences.

(1), installation process
Measure and lay out→Structural drilling, burying components→Installation skeleton→Lighting line reservation→Installation of aluminum Plastic board → glue, cleaning and tearing film → installation pre ssure limit.
(2) Installation and construction methods
1. Make connectors according to design requirements. The finished connecting iron parts are galvanized and rust-proofed.
2. Embedded parts are connected by welding. When installing embedded parts, first carefully measure the installation site to determine the center position and surrounding position. Use the same reference line for segmented control. The errors should be adjusted in time and should not be accumulated.
3. Check the vertical and facade position of the wall.
4. Keel installation: The connecting parts are welded and fixed with the embedded parts on the main structure. When there are no embedded iron parts embedded in the main structure, holes can be drilled in the main structure to install expansion bolts and Fasten with connecting iron parts.
Install the skeleton using the welding method. Check the elevation and centerline position at any time during installation. At the same time, the cross-section connecting welds should be treated with anti-rust paint, and the fixed connectors should be covered with hidden inspection records, including the welding of connectors. Seam length, thickness, location, embedding elevation, quantity, and embedding depth.
(3) Installation of aluminum-plastic panels:
First tap and mill the screw holes, and use rivets (or screws) to fix the aluminum-plastic panel facings piece by piece to the steel frame. Above; the gap between the panels should be 10~15mm before injecting silicone weather-resistant sealant; it is strictly forbidden to remove the packaging paper before installing the aluminum panels, and tear off the packaging protective film before completion.
(4). Acrylic character production and construction technology
1. Acrylic characters are divided into three types according to their shapes:
(1) Flat drum (2) Pointed drum character; (3) Round drum character. Other shapes basically evolved from these three types. For example, a pointed drum can evolve into a diamond shape, and a round drum can evolve into an arc shape. However, the shape of the characters will be completely different depending on the choice of tool and the depth of the cutter.
(1) Production and requirements of flat drum characters:
Use copy paper to trace the desired characters on the density board, leaving 5cm on each side, and install them with a manual engraving machine Use the corresponding straight knife to cut out the mold along the outer line of the word (the inner line is taken internally, and the other lines are taken outer). After the mold is cut out, use a file to smooth the mold. Then use a file and sandpaper to grind the sides and corners of the male and female molds of the characters into arc shapes.
It must be smooth and even, and finally smooth with sandpaper. You can also use a computer engraving machine to engrave the mold, add enough height and then smooth the edges and corners.
(2) The production and requirements of the pointed drum characters:
The first step: The production method of the flat drum characters is the same, except that the sides and corners are not ground yet. Arc shape.
The second step: heightening and shaping. According to the size of the characters and the width of the strokes (based on the widest stroke, draw a middle line starting from the second layer to see if the inclination on both sides is a 90-degree right angle, use this angle to position the thickness of the heightening, and then select the appropriate Install a 45-degree bevel knife on a multi-functional milling machine, and cut out a sharp drum with the face facing downwards. Use 502 glue or three-second glue to drip glue on each part of the sharp point to make it harder and not damaged during pre ssing. There are no sharp parts in the mold. Those that need to be raised should be raised and those that need to be repaired should be repaired properly. Extra large characters cannot be purchased and can only be made by hand.
(3) Round drum characters. The production and requirements:
The first step: The production method is the same as the flat drum character, except that the sides and corners are not ground into arcs for the time being.
The second step. Step: Heightening and shaping. The thickness of the heightening should be proportional to the size of the characters and the result should be beautiful. The steps are roughly the same as those for making pointed drum characters, except that the cutter is a rounded corner knife.
(5) Installation and construction plan
1. Cut the materials according to the specifications and dimensions confirmed in the design drawings, process the semi-finished products in the factory, and install them on the construction site.
2. Installation. At this time, the font frame should be firmly connected to the aluminum plate of the billboard and the base layer, the lighting circuit should be connected to the reserved circuit pipe, and the lamp tubes should be reasonably distributed according to the design requirements.
3. After installation, clean the surface and protect the finished product. . Alternate movement and segmented delivery to improve efficiency.
