A, aluminum plastic plate material and structure
Aluminum-plastic plate is a new type of decoration material, with a series of excellent performance, after coming out, it has been widely used in curtain wall, indoor and outdoor decoration and other fields, creating a new world of contemporary architectural decoration.
Alleged aluminium model board, it is to point to by aluminium and plastic compound and become plank.Specifically, aluminum plate and plastic core material in a certain process conditions through special adhesive bonding and composite plate.In fact, it is generally used as the front, back aluminum coating, and then composite plastic core material.The front panel is generally coated with decorative coating and the back panel with protective coating.
About the structure of aluminium model board, it is sandwich type structure generally speaking, this is a kind of comparison image metaphor, two aluminium board sandwiched between a layer of plastic core material.In fact, the structure of aluminum plastic plate is much more complex.
Ii. Classification and specification of aluminum plastic plate
1. Classification of aluminum plastic plate
Aluminous model board breed is more, and it is a kind of new-style material, because this does not have unified classification method up to now, press use normally,
Product function and surface decoration effect are classified.
(1) classification by use
A. Aluminum plastic plate for building curtain wall
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.Aluminum materials should meet the requirements of GB/T 3880, generally 3000, 5000 series of aluminum alloy plate, coating should be fluorocarbon resin coating.
B. Aluminum plastic plate for exterior decoration and advertising
The upper and lower aluminum plates shall adopt anti-rust aluminum with thickness not less than 0.20mm, and the total thickness shall not be less than 4mm.The coating usually adopts fluorocarbon coating or polyester coating.
C. Aluminum plastic plate for indoor use
The thickness of upper and lower aluminum plate is generally 0.20mm, the minimum thickness is not less than 0.10mm aluminum plate, the total thickness is generally 3mm.
The coating adopts polyester coating or acrylic coating.
(2) according to product function classification
A. fire prevention board
Choose flame retardant core material, the combustion performance of the product to reach the combustible level (B1) or non-combustible level (A);At the same time, other performance indicators must also meet the technical requirements of aluminum plastic plate.
B. Antibacterial and mildew-proof aluminum plastic plate
Coating the coating with antibacterial and bactericidal effect on the aluminum plastic plate, so that it can control the activity and reproduction of microorganisms and ultimately kill bacteria.
C. Anti-static aluminum plastic plate
Antistatic aluminum-plastic plate is made of antistatic coating coated aluminium plate, surface resistivity under 109 Ω, smaller than normal aluminum-plastic plate surface resistivity, therefore not easy to produce static electricity, dust in the air of not easy also attached on the surface.(3) according to the surface decoration effect to classify
A. Decorative aluminum plate with coating
Apply various decorative coatings on the surface of aluminum plates.Commonly used fluorocarbon, polyester, acrylic coating, mainly including metal color, plain color, pearl color, fluorescent color, decorative effect, is the most common market varieties.
B. Anodized aluminum plastic plate
The aluminum alloy panel is treated by anodizing in time and has unique colors such as rose and bronze, which can play a special decorative effect.
C. Laminated decorative composite board
It is the color grain film according to the set process conditions, rely on the role of the adhesive, make the color grain film adhesive coating primer on the aluminum plate or directly stick on the aluminum plate after degreasing treatment.Main breed has grain, wood grain board to wait.
D. Color printed aluminum plate
Different patterns through advanced computer phototypesetting printing technology, the color ink on transfer paper printing out a variety of imitation of natural patterns, and then through heat transfer technology indirectly copied on the aluminum plate out of a variety of imitation of natural patterns.Can satisfy the originality of stylist and the individuation choice of owner.
E. Brushed aluminum sheet
Aluminium alloy face plate that USES surface to pass drawing processing, common is gold drawing and silver drawing product, bring different visual experience to the person.
F. Mirror aluminum plastic plate
The surface of aluminum alloy panel is polished like a mirror.
2. Specification of aluminum plastic plate
Common specifications of ordinary aluminum plastic plate are as follows:
A. The total thickness is 3mm, 4mm and 6mm
B. Width 1220mm and 1500mm
C. the length of 1000mm, 2440mm, 3000mm, 4000mm, 6000mm d. the size of 1220*2440mm aluminum plastic plate in the industry is known as the standard plate
