What is auminum composite plate

Aluminum composite plate is a composite material which is processed with chemically coated aluminum plate as surface material and polyethylene plastic as core material on special auminum composite plate production equipment. The unique performance of aluminum composite panel itself determines its wide use: it can be used for building exterior wall, curtain wall panel, old building renovation, interior wall and ceiling decoration, advertising signs, display platform, purification and dust prevention engineering. It belongs to a new type of building decoration material.

The advantages and disadvantages of auminum composite plate are introduced

The shortcomings of auminum composite plate

One is the structure of the aluminum material for three layers, commonly on both sides of 0.1 a 0.5 mm thick aluminum outside layer, intermediate sandwich material is mainly used in low pressure polyethylene (hdpe) polymer materials, such as in a tree, vinegar class gluewater core material and glue containing toxic ingredients, and fire prevention, weather resistance, durability, anti-aging, such as poor performance, Toxic gases that are harmful to human health are released during combustion or at high temperatures or even under sun exposure.

Second, the composite strength is not high, curved curved surface is easy to break, local heat when the core material will expand causing surface aluminum deformation and fall off, coupled with its thermal expansion coefficient is generally larger than keel and building, often appear bulge phenomenon so as to lose effect and affect the appearance;

Third, the installation is generally shared with the main body of the building lightning protection device, and the auminum composite plate core material and fasteners are bad conductors of electricity, the current can not pass quickly, easy to suffer from high voltage lightning attack;

Fourth, the strength of the material itself is not high because of its strength against wind pressure. At present, the high-rise buildings in foreign advanced countries have rarely used aluminum-plastic composite panels as curtain walls, and use single-layer aluminum panels with relatively high safety and reliability.

The advantages of auminum composite plate

Aluminum composite plate is characterized by light weight, appropriate steel, shock absorption and sound insulation, and its decorative effect is good, its surface can be anti-corrosion, ginning, painting, printing and other secondary processing, and aluminum plate can be comparable, but the cost is much lower. People who support this view believe that aluminum composite plate after years of development, technology gradually mature, materials before delivery generally through corrosion resistance, weather resistance, crash resistance, bending resistance, compression and so on processing, in use has a certain safety and reliability. In high-rise buildings using aluminum plastic composite plate curtain wall, although the wind pressure requirements are high, but the size of the compressive strength is not only related to the quality of the wall material itself, but also related to the installation size specification, the length and width ratio of the plate and keel configuration of the density and so on. If strictly in accordance with the requirements of the construction code, generally meet the quality indicators of the aluminum composite plate can be used as the curtain wall of high-rise buildings. In addition, the current lightning-proof technology and measures have been more mature, high-rise buildings are generally thoughtful in this respect, as for the aluminum plastic composite panel curtain wall due to lightning damage, in practical application is extremely rare, has not found any precedent at home and abroad. Therefore, it can be widely used in the exterior decoration of high-rise buildings.

If you need to decorate the wall, or the need for mobile advertising decoration, or the need for wallboard decoration, you can choose and buy aluminum plastic composite plate, the quality of aluminum plastic composite plate is far higher than other wallboards of the same type. And aluminum plastic composite plate manufacturers are very many, among which there is no lack of exquisite production quality of some auminum composite plate. Customers can use hand percussion method to verify the quality of aluminum composite plate in the end, whether it meets their own needs and standards.
