Metal material knowledge | Aluminum-plastic composite panel
Aluminum-plastic composite panel, referred to as aluminum-plastic panel, is a kind of aluminum composite panel, it is a composite material processed on special aluminum-plastic panel production equipment with chemically treated coated aluminum panel as the surface material and polyethylene plastic or high mineral as the core material. The unique properties of the aluminum-plastic composite panel itself determine its wide range of uses: it can be used for building exterior walls, curtain wall panels, renovation and renovation of old buildings, interior wall and ceiling decoration, advertising signs, display stands, purification and dust-proof. project. It belongs to a new type of building decoration material.
Material properties and characteristics
As a new type of decorative material, aluminum-plastic composite panel (also known as aluminum-plastic panel) has been introduced to China from Germany in the late 1980s and early 1990s. The construction method, excellent processing performance, excellent fire resistance and noble quality are quickly favored by people.
1．Super-strength peeling degree: The aluminum-plastic composite panel adopts a new process, which improves the most critical technical index of the aluminum-plastic composite panel-peel strength to an excellent state, so that the flatness and weather resistance of the aluminum-plastic composite panel are improved accordingly.
2．The material is easy to process: the weight per square meter of the aluminum composite panel is only about 3.5-5.5 kg, so it can reduce the damage caused by the earthquake, and it is easy to handle. Its superior construction only needs simple woodworking tools to complete cutting, Various shapes of cutting, planing, bending into arcs and right angles can be made to make various changes, which are easy to install and reduce construction costs.
3．Excellent fire performance: The middle of the aluminum-plastic panel is a flame-retardant PE plastic core material, and the two sides are extremely difficult to burn aluminum layers. Therefore, it is a safe fireproof material that meets the fire resistance requirements of building regulations.
4．Impact resistance: strong impact resistance, high toughness, no damage to the topcoat by bending, strong impact resistance, and no damage caused by wind and sand in areas with large sandstorms.
5．Super weather resistance: Due to the use of PVDF fluorocarbon paint based on KYNAR-500, it has unique advantages in weather resistance, no matter in the hot sun or in the cold wind and snow, it will not damage the beautiful appearance, it can be Up to 20 years without fading.
6．The coating is uniform and colorful: After chemical treatment and the application of Henkel's film technology, the adhesion between the paint and the aluminum composite panel is uniform and the color is diverse.
7．Easy to maintain: Aluminum-plastic panels have been significantly improved in terms of pollution resistance. my country's urban pollution is relatively serious, and it needs maintenance and cleaning after a few years of use. Due to its good self-cleaning properties, it only needs to use a neutral cleaning agent and water, and after cleaning, the board will be permanently as new.
8．Easy to process: Aluminum-plastic panel is a good material that is easy to process and form. It is also an excellent product for the pursuit of efficiency and time, which can shorten the construction period and reduce costs. Aluminum composite panels can be cut, cut, slotted, band sawed, drilled, countersunk, or cold-formed, cold-folded, cold-rolled, riveted, screwed, or glued.
Product technology and classification
There are many varieties of copper-containing aluminum-plastic panels, and it is a new type of material. The total thickness of 3mm, 4mm, 6mmb, width 1220mm, 1500mmc. Inside is called the standard board. Therefore, as of classification, there is no unified classification method, and it is usually classified according to use, product function and surface decoration effect.
1. Sort by use
a. Aluminum-plastic panels for building curtain walls—the minimum thickness of the upper and lower aluminum panels should not be less than 0.50mm, and the total thickness should not be less than 4mm. The coating should be fluorocarbon resin coating.
b. Aluminum-plastic panels for exterior wall decoration and advertising—the upper and lower aluminum panels are made of rust-proof aluminum with a thickness of not less than 0.20mm, and the total thickness should not be less than 4mm. The coating generally adopts fluorocarbon coating or polyester coating.
c. Indoor aluminum composite panels - the upper and lower aluminum panels generally use aluminum panels with a thickness of 0.20mm, the minimum thickness is not less than 0.10mm, and the total thickness is generally 3mm. Coatings are polyester or acrylic.
2. Sort by product function
a. Fireproof board - use flame retardant core material, and the combustion performance of the product reaches flame retardant grade (B1 grade) or non-combustible grade (A grade); at the same time, other performance indicators must also meet the technical requirements of aluminum composite panels.
b. Antibacterial and anti-mildew aluminum-plastic panels - coating the aluminum-plastic panels with antibacterial and bactericidal coatings to control the reproduction of microbial activities and ultimately kill bacteria.
c. Anti-static aluminum-plastic panels - anti-static aluminum-plastic panels are coated with anti-static paint, and the surface resistivity is below 109Ω, which is smaller than that of ordinary aluminum-plastic panels, so it is not easy to generate static electricity, and dust in the air is also Not easy to adhere to its surface.
3. Classified by surface decoration effect
a. Coated decorative aluminum-plastic panels - Coating various decorative coatings on the surface of aluminum panels. Commonly used are fluorocarbon, polyester, acrylic coatings, mainly including metallic, plain, pearlescent, fluorescent and other colors, which have a decorative effect.
b. Oxidized and colored aluminum-plastic panel - the aluminum alloy panel is treated in time by anodizing, and has unique colors such as rose red and bronze, which has a special decorative effect.
c. Film decorative composite board - that is to use the color pattern film according to the set process conditions and rely on the action of the adhesive to make the color pattern film adhesive on the primed aluminum plate or directly on the degreased aluminum plate. In the above, the main varieties are gang grain, wood grain board and so on.
d. Color-printed aluminum-plastic board - different patterns are printed on the transfer paper with various imitation natural patterns through advanced computer graphics printing technology, and then indirectly copied on the aluminum-plastic board through thermal transfer technology a variety of imitation natural patterns.
e. Brushed aluminum-plastic panel - The aluminum alloy panel with brushed surface is used, and the common ones are gold brushed and silver brushed products, which bring different visual enjoyment to people.
f. Mirror aluminum composite panel - the surface of the aluminum alloy panel is polished to look like a mirror.
