The scientific name of aluminum-plastic panel is also called aluminum-plastic composite panel. It is a three-layer composite panel with plastic as the star layer and aluminum on both sides, and a decorative and protective coating and film on the surface of the panel. Material. The common size on the market is 2 meters 44 times 1 meter 22, of course, other sizes can also be customized according to customer requirements, for example, 2 meters long, 3 meters long, 4 meters long. According to different specifications, its thickness varies from 1 mm to 6 mm. Generally, the thickness of 4 mm is used for outdoor use, and the aluminum composite panel below 4 mm is used for indoor use.
Aluminum composite panels can be divided into: 1 Class b 1 and class a aluminum composite panels with fire resistance This aluminum composite panel is mostly used for outdoor and indoor public spaces that require Manchuria fire protection. 2 Antibacterial and mildew proof aluminum composite panel This type of aluminum composite panel is mostly used in damp and poorly ventilated spaces. 3 Aluminum composite panel with antistatic coating This type of aluminum composite panel is mostly used in computer control rooms and other spaces. The space decorated with this type of aluminum composite panel is not easy to generate static electricity, and the dust in the air will not adhere to the surface of this decorative material.
According to this use, it can be divided into: 1 Building wood wall aluminum composite panel This type of aluminum composite panel requires that the minimum thickness of the aluminum skin is not less than 0.5 mm, and the total thickness is not less than 4 mm. Generally, the surface coating adopts fluorocarbon resin technology. 2 Advertising special aluminum composite panel This kind of aluminum-plastic panel requires that the thickness of the upper and lower aluminum cladding is not less than 0.2 mm, and the total thickness of the aluminum-plastic panel is not less than 4 mm, and the layer is generally made of fluorocarbon layer or polyester layer. 3 Aluminum-plastic panels for indoor use The thickness of the aluminum skin above and below this type of aluminum composite panel is generally 0.2 mm, and the minimum thickness is not less than 0.1 mm. The total thickness of this aluminum panel is generally 3 mm, and the coating is polyester coating or acrylic coating.
Because the quality of this type of aluminum composite panel is not very good, it is generally not used on the wall of the decorative space, and most of it is used on the top surface of the space, such as the mirrored ceiling aluminum composite panel.
First of all, it is the price advantage. The price of aluminum composite panel is much lower than that of aluminum veneer. The second is that the material can be processed at will on site, unlike aluminum veneer, which has a long processing cycle and needs to be customized in the factory. The third is that the flatness of the aluminum composite panel is better than that of the aluminum veneer, such as the mirror aluminum composite panel, the aluminum veneer spraying cannot be achieved. Fourth, the sound insulation and shock absorption effect of the aluminum composite panel is better than that of the aluminum veneer.
But this aluminum composite panel also has its disadvantages, mainly in: 1 The core of the aluminum composite panel is a bad conductor of electricity, the current cannot pass through quickly, and it is easily attacked by high-voltage lightning. 2. Since the core of the aluminum composite panel is made of polyethylene material, it is poor in terms of fire resistance, weather resistance and aging resistance. At the same time, it will release harmful gases when burning, causing serious damage to human health. 3 When the bending strength is too large, the surface will break and the paint will fall off. 4 Since this aluminum-plastic panel is a decorative panel made of two materials, the thermal expansion coefficients are different in the natural environment, and the panel is easily deformed, thus affecting the aesthetic effect of the decorative surface.
To choose a good aluminum composite panel, you must do it: take a look at the principles of two measurements, three folds, four burns, and five essentials A look: to see whether the surface of the aluminum composite panel is smooth and smooth, without ripples, and whether there are any flaws or scratches. Two sides: measure whether the thickness of the aluminum composite panel meets the international requirements. Generally, the inner wall panel is 3 mm, the outer wall panel is generally more than 4 mm, and the thickness of aluminum must be 0.5 mm. Three folds: Break the corner of the aluminum-plastic panel to see if the aluminum-plastic panel is easy to break. If it is easy to break, it is not a clothing material or mixed with other materials. Four burning: If the material in the middle of the aluminum composite panel is completely burned, it means that it is a real batch material. If there are impurities after burning, it is an inferior aluminum composite panel. Five requirements: It is to ask for the quality inspection report of the manufacturer, as well as the international quality system certification.
