1. Classification of ACP sheets:
There are many kinds of ACP sheet
and it is a new material. So far, there is no unified classification method. Usually, it is classified by use, product function and surface decoration effect.
(1) Classification by use:
A. Aluminum-plastic panels for curtain walls of buildings:
The minimum thickness of upper and lower ACP sheets
shall not be less than 0.50 mm, and the total thickness shall not be less than 4 mm. Aluminum materials should meet the requirements of GB/T 3880. Generally, 3000, 5000 series of aluminium alloy sheets should be used, and fluorocarbon resin coatings should be used for the coatings.
B. Aluminum-plastic panels for exterior wall decoration and advertising:
Rust-proof aluminium with thickness not less than 0.20 mm is used for upper and lower ACP sheets
, and the total thickness should not be less than 4 mm. Fluorocarbon coatings or polyester coatings are commonly used for coatings.
C. Indoor ACP sheets:
Aluminum sheets with thickness of 0.20 mm and minimum thickness of no less than 0.10 mm are generally used for upper and lower ACP sheets
, and the total thickness is generally 3 mm. The coating is made of polyester or acrylic acid.
(2) Classification by product function:
A. Fireproof board:
The flame retardant core material is selected, and the combustion performance of the product reaches the level of flame retardant (B1) or non-combustible (A). At the same time, other performance indicators must also meet the requirements of the technical indicators of the aluminum-plastic sheet.
B. Antibacterial and mildew-proof ACP sheets:
Coatings with antimicrobial and bactericidal effects are coated on the ACP sheet to control microbial activity and reproduction and ultimately kill bacteria.
C. Antistatic ACP sheets:
Antistatic ACP sheet is coated with antistatic coating. Its surface resistivity is below 109, which is smaller than that of ordinary ACP sheets. Therefore, it is not easy to generate static electricity and dust in the air is not easy to adhere to its surface.
(3) According to the effect of surface decoration:
A. Coated decorative ACP sheets:
All kinds of decorative coatings are coated on the surface of ACP sheets. Fluorocarbon, polyester and acrylic acid coatings are widely used, including metal, plain, pearlescent and fluorescent colors. They have decorative effect and are the most common varieties in the market.
B. Oxidized colored ACP sheets:
The aluminium alloy panel treated by anodic oxidation in time has unique colors such as rose red and bronze, which has a special decorative effect.
C. Decorative laminate with film:
That is to say, according to the set technological conditions and depending on the role of adhesives, the color film adhesives are pasted on the primer coated ACP sheets or directly on the degreased ACP sheets. The main varieties are gang grain, wood grain board and so on.
D. Color printed ACP sheets:
Different patterns are printed on transfer paper by advanced computer Phototypesetting technology, and then various natural imitation patterns are indirectly copied on ACP sheets by thermal transfer technology. This can satisfy the designer's creativity and the owner's personalized choice.
E. Wire-drawn ACP sheets
Aluminum alloy panels with surface treated by wire drawing are commonly made of gold and silver wire drawing products, which bring different visual perception to people.
F. Mirror finish aluminum sheet:
The surface of aluminium alloy panel is polished like a mirror.
