Fireproof Aluminum Composite Panel
Aluminum composite panel refers to a new type of decorative materials which has a series of excellent performance. It has been widely applied in curtain wall, indoor and outdoor decoration and other fields since it's created opening a new world for contemporary architectural decoration.
Aluminum composite panel classified by products function
a. fireproof aluminum composite panel
Non combustible aluminium composite panel's main material is the flame retardant core material that has the combustion performance reaching the refractory level (class B1) or non-combustible (class A); At the same time, other performance indicators should meet the technical requirements of the aluminum composite panel.
b. antibacterial and anti-mold aluminum composite panel
The antibacterial and bactericidal coating is coated on the aluminum composite panel so that it has the function of controlling microbial activity and eventually killing bacteria.
c. Anti-static aluminum composite panel
The antistatic aluminum composite panel is coated with an antistatic coating. The surface resistivity is below 109Ω smaller than that of the ordinary aluminum composite panel, thus, it is not easy to generate static electricity and the dust in the air is not easy to attach to its surface...
The fire protection grade of the aluminum composite panel is determined by two indexes, namely the national compulsory standard GB8624 and GB/T17748 'aluminum composite panel'.
The combustion performance of building materials in China is classified as follows:
Class A: non-combustible building materials.
Class B1: refractory building materials.
Class B2: combustible building materials.
Class b: flammable building materials.
The grade of the fireproof aluminum composite panel should not be lower than B1.
1. Detection indicators and requirements of the fire-resistant aluminum composite panel (class B1):
According to GB/T8625-88 standard, the average length of each group specimens is 150 mm or more, (either remaining length > 0), and the average flue gas temperature is 200 ℃ or less.
According to GB/ t8626-88, the flame tip height indicator is below 150mm, and the phenomenon of burning filter paper is not allowed.
According to GB/ t8627-1999, the smoke density level (SDR) is less than 75.
2. Detection indicators and requirements of the fire-resistant aluminum composite panel (A class non-combustible composite sandwich material):
According to GB/T8625-88 standard, the average length of each group specimens is 350 mm or more, (either remaining length > 200mm), and the average flue gas temperature is 125 ℃ or less and no combustion on the back of the specimen.
According to GB/ t8627-1999, the smoke density level (SDR) is less than 15
According to GB/ t14402-93 and GB/ t14403-93 standard, the material heat 3 value is less than or equal to 4.2MJ/kg, and the released heat of the unit area of the specimen is less than or equal to 16.8MJ/m2;
Features of the fireproof aluminum composite panel:
The aluminum composite panel is a new type of decoration material, compared with other decorative materials, it has many incomparable advantages. The reason for this is that the aluminum composite panel is a kind of composite material, which can obtain many new properties which are not in the original material. On the other hand, the aluminum composite panel is a high-tech product, which has high technical content in both production and application. Many advanced technologies are adopted in the aluminum composite panel production, such as rolling process and continuous thermal composite process ensuring the full play of material performance.
Main characteristics of the aluminum composite panel:
1. Light in weight
The aluminum composite panel is made of aluminum and plastic composite core material with smaller density, and therefore when compared to aluminum (or other metal) with the same rigid or have the same thickness, it is lighter.
2.Good in rigidity
The aluminum composite panel cleverly utilize the mechanical principle of the I shaped steel structure, and it gives its unique mechanical properties. Furthermore, the aluminum composite panel is compounded under high temperature. Besides, in the process, the two layers of the aluminum composite panel are in a certain state of tension, after molding and cooling, because of the shrinkage rate of the symmetrical aluminum plate and core material, the internal stress of sheet is formed and good rigidity is created.
3. Rich in color and suitable for decoration.
The picture plane of the aluminum composite panel can be made into a variety of colors and can be designed into all kinds of pictures. In addition, photocopying technology enables to simulate the patterns of granite, wood grain and metal to provide the design with precise texture and high quality. Rich colors and pattern designs meet different environment making a harmonious feeling. Colors and patterns' perfect combination achieve a great artificial unification giving out a Bright and soft visual feast. The curtain wall that is decorated with the aluminum composite panel can be compared to the gorgeous glass curtain wall and elegant stone curtain wall. Under the sunlight, it is both gorgeous and dignified, while avoiding light pollution.
4. High surface smoothness.
The aluminum composite panel is produced by the continuous thermal composite production process, so the surface flatness is higher than that of the single material, especially the large size plate. When used for building decoration, it shows a smooth and uniform feeling.
5. Good durability
The aluminum composite panel adopts the thermal composite technology of metal and core material, and the bonding is firm, and the surface coating is selected according to the different materials used in the environment. Three kinds of coatings are commonly used, namely fluorocarbon coating, polyester coating, and acrylic coating, among which fluorocarbon coating has excellent weather ability, which is widely used in curtain wall decoration and special occasions. Experimental studies have shown that it can be used for more than 20 years in harsh outdoor environments.
6. Excellent fireproof performance.
The fire aluminum composite panel adopted new research and development of the core material. The core material filled or inorganic filling material, so the improvement of the performance of the fire made a leap which can achieve B1 level standard satisfying the requirement of building regulations.
