1. Material and structure of aluminum-plastic panel:
Aluminum-plastic panel is a new type of decorative material with a series of excellent properties. It has been widely used in curtain wall, indoor and outdoor decoration and other fields soon after it came out, creating a new world of contemporary architectural decoration.
The so-called aluminum-plastic panel refers to a panel made of aluminum and plastic. Specifically, it is a plate made of aluminum plate and plastic core material bonded and compounded by special adhesive under certain process conditions. In fact, the front and back aluminum plates are usually coated first, and then compounded with the plastic core material. The front panel is generally given a decorative coating and the back panel is given a protective coating. Regarding the structure of the aluminum-plastic panel, generally speaking, it is a sandwich structure. This is a vivid metaphor. There is a layer of plastic core material sandwiched between two layers of aluminum panels. In fact, the structure of aluminum-plastic panels is much more complicated.
2. Classification and specifications of aluminum-plastic panels:
1. Classification of aluminum-plastic panels:
There are many varieties of aluminum-plastic panels, and they are a new type of material. Therefore, there is no unified classification method so far. They are usually classified according to their use, product function and surface decoration effect.
(1) Classified by purpose:
a. Aluminum-plastic panels for building curtain walls:
The minimum thickness of the upper and lower aluminum plates shall not be less than 0.50mm, and the total thickness shall not be less than 4mm. The aluminum material should meet the requirements of GB/T 3880. Generally, aluminum alloy plates of 3000 and 5000 series should be used, and the coating should be fluorocarbon resin coating.
b. Aluminum-plastic panels for exterior wall decoration and advertising:
The upper and lower aluminum plates are made of anti-rust aluminum with a thickness not less than 0.20mm, and the total thickness should not be less than 4mm. Coating generally adopts fluorocarbon coating or polyester coating.
c. Aluminum-plastic panels for indoor use:
The upper and lower aluminum plates generally use aluminum plates with a thickness of 0.20mm and a minimum thickness of not less than 0.10mm, and the total thickness is generally 3mm. The coating is polyester coating or acrylic coating.
(2) Classification by product function:
a. Fire board:
The flame-retardant core material is selected, and the combustion performance of the product reaches the 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-plastic panels.
b. Antibacterial and mildew-proof aluminum-plastic panels:
Apply antibacterial and bactericidal coatings on aluminum-plastic panels to control microbial activity and reproduction and ultimately kill bacteria.
c. Antistatic aluminum-plastic panel:
The antistatic aluminum-plastic panel is coated with antistatic paint, and its surface resistivity is below 109Ω, which is smaller than that of ordinary aluminum-plastic panels. Therefore, it is not easy to generate static electricity, and it is not easy for dust in the air to adhere to its surface.
(3) Classified by surface decoration effect:
a. Coated decorative aluminum-plastic panel:
Coating various decorative coatings on the surface of the aluminum plate. Commonly used are fluorocarbon, polyester, and acrylic coatings, mainly including metallic colors, plain colors, pearlescent colors, fluorescent colors and other colors, which are decorative and are the most common varieties on the market.
b. Oxidized colored aluminum-plastic panel:
The aluminum alloy panel is processed in time by anodic oxidation, and has unique colors such as rose red and bronze, which have a special decorative effect.
