Aluminum Plastic Board Lecture Hall-Aluminum Plastic Board Knowledge Aluminum Plastic Board Material Structure Classification and Specification I. Material and structure of aluminum-plastic boards:
Aluminum -plastic plate is a new type of decorative material, which has a series of excellent performance. It has been widely used in the fields of curtain walls, indoor and outdoor decoration, and created a new world of contemporary architectural decoration.
The so -called aluminum plastic board refers to the plate compounded by aluminum and plastic. Specifically, aluminum plates and plastic core materials are compounded by bonding of special adhesive under certain process conditions.
In fact, it is generally used as positive and back aluminum plates to paint, and then compounds with plastic core materials. The front panel is generally coated with decorative coating, and the back panel coating protective coating.
Regarding the structure of aluminum -plastic plates, it is generally a sandwich structure. This is a comparative metaphor. A layer of plastic core material is sandwiched in the middle of the two layers of aluminum plates.
In fact, the structure of aluminum plastic panels is much more complicated.
Second, the classification and specifications of aluminum plastic plates:
1. Classification of aluminum plastic board:
There are many types of aluminum -plastic boards, and they are a new material. Therefore, there is no unified classification method so far. Usually, it is classified according to use, product function and surface decoration effect.
(1) Classification according to use:
A. Aluminum -plastic panel for building curtain walls:
The minimum thickness of the upper and lower aluminum plates is not less than 0.50mm, and the total thickness should not be less than 4mm.
Aluminum materials should meet the requirements of GB/T 3880. Generally, 3000, 5000 and other series of aluminum alloy plates should be used. The coating should be coated with fluorocarbon resin.
B. Outer wall decoration and advertising aluminum plastic board:
The upper and lower aluminum plates adopt rust -proof aluminum with a thickness of not less than 0.20mm, and the total thickness should not be less than 4mm. The coating is generally used with fluorocarbon coating or polyester coating.
C. Aluminum -plastic plate for indoor:
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 uses polyester coating or acrylic coating.
(2) Classification by product function:
Select the flame retardant core material, the product combustion performance reaches the difficulty level (B1 level) or non -combustible (A -level); at the same time, other performance indicators must also meet the technical indicators of aluminum plastic boards.
B. Antibacterial and moldy aluminum plastic plate:
Painting the coatings with antibacterial and sterilization effects on aluminum -plastic panels, so that it has the effect of controlling microbial activity and eventually killing bacteria.
C. Anti -static aluminum plastic board:
The anti -static aluminum plastic plate is coated with anti -static coating coating aluminum -plastic panels. The surface resistivity is below 109Ω, which is smaller than the surface resistivity of ordinary aluminum plastic plates. Therefore, it is not easy to generate static electricity. The dust in the air is not easy to attach to its surface.
(3) Classification according to the surface decoration effect:
A. Coating decorative aluminum plastic board:
Apply various decorative coatings on the surface of the aluminum plate.
It is generally used in fluorocarbon, polyester, and acrylic coating, which mainly include metal, plain, pearl, fluorescent color and other colors. It has decorative effects and is the most common variety in the market.
B. Oxidation color aluminum plastic plate:
The use of anode oxidation Timely and timely treatment of aluminum alloy panels have unique colors such as rose red and copper colors, and play a special decorative effect.
C. Film decoration composite board:
That is, the color pattern film is based on the set process conditions and rely on the effect of adhesive to make the colorful film adhesive on the aluminum plate with a primer or directly on the abandoned aluminum plate.
The main varieties are job patterns, wood grain boards, etc.
D. Color printed aluminum plastic board:
Different patterns printing technology through advanced computers, printed colorful inks on the transfer paper various imitation natural patterns, and then indirectly copy various imitation natural patterns on aluminum -plastic plates through thermal transfer technology. Can satisfy the designer's creativity and the individual choice of the owner.
E. Brushing aluminum plastic board:
The aluminum alloy panels treated by the surface are commonly treated with gold and silver products, which brings different visual feelings.
F. Mirror aluminum plastic board:
The surface of the aluminum alloy panel is polished, like a mirror.
2. Specifications of aluminum plastic boards:
The common specifications of ordinary aluminum plastic boards are as follows:
A. The total thickness of 3mm, 4mm, 6mmb. Width 1220mm, 1500mmc. 1000mm, 2440mm, 3000mm, 4000mm, 6000mmd. Size 1220*2440mm aluminum plastic boards are called standard boards in the industry.
