What Is an Aluminum Composite Panel?

As a new type of decorative material, aluminum-plastic composite board (also known as aluminum-plastic board) was introduced from Germany to China in the late 1980s and early 1990s. The construction method, excellent processing performance, excellent fire resistance and noble quality are quickly favored by people.

Aluminum-plastic board

In foreign countries, there are many names of aluminum-plastic panels, some are called Aluminum Composite Panels; others are called aluminum

Aluminum-plastic composite board is composed of multiple layers of materials, and the upper and lower layers are of high purity

1. Exterior wall and curtain wall panels of the building.

2. Modification and renovation of old building exterior walls.

3. Balcony, equipment unit, indoor compartment.

4. Panel, identification plate, display stand.

5.Interior wall installation

Super peeling

A new process is adopted for the aluminum-plastic composite board, which improves the peeling strength, the most important technical index of the aluminum-plastic composite board, to improve the flatness and weatherability of the aluminum-plastic composite board.

Easy processing

The aluminum-plastic board weighs only about 3.5-5.5 kilograms per square meter, so it can reduce the damage caused by the earthquake and is easy to transport. Its superior workability requires only simple woodworking tools to complete cutting, cutting, and planing. Various shapes such as sides, bends into arcs, and right angles can cooperate with the designer to make various changes, and the installation is simple and quick.

Dry hanging aluminum-plastic board construction process

The laying-out work is carried out according to the actual centerline and elevation point of the civil engineering; the design of the finish is based on the axis of the building. The aluminum-plastic plate skeleton is composed of horizontal and vertical members. First, the position line of the vertical rod is played. The anchoring point of the vertical member is determined.

, install the fixed connector on the basis of pay-off, use electric welding to fix the connector, the anti-rust paint at the weld is twice. The connecting piece is fixed by welding with the embedded parts on the main structure. When no embedded iron parts are embedded on the main structure, an expansion bolt can be punched in the main structure to fix the connecting iron parts.

Install the skeleton. Use a welding method to install the skeleton. Check the elevation and centerline position at any time during the installation. At the same time, the cross-section connection welds shall be treated with anti-rust paint. Set elevation, quantity, embedding depth.

Install the aluminum-plastic plate on the inner frame of the profile, first tap and mill the screw holes, and use rivets to fix the aluminum-plastic plate finish on the profile steel frame one by one; the gap between the plate is 10 to 15, and then inject silicone Weather-resistant sealant; it is strictly forbidden to remove the packaging paper before installation of the aluminum plate until the packaging protective film is torn off before completion; construction is performed according to the direction indicated by the arrow of the aluminum-plastic plate.

Discoloration and discoloration of plastic board

The discoloration and discoloration of the aluminum-plastic board are mainly caused by improper selection of the board. Aluminum-plastic board is divided into indoor board and outdoor board. The surface coating of the two boards is different, which determines the different occasions for which it is applicable. The surface of the board used in the interior is generally sprayed with a resin coating. This coating cannot adapt to the harsh outdoor natural environment. If it is used outdoors, it will naturally accelerate its aging process and cause discoloration and discoloration. The surface coating of outdoor aluminum-plastic board is generally selected from the anti-aging and UV-resistant polyfluorocarbon coating, which is expensive. Some construction units have deceived the owners, posing as anti-aging and anti-corrosion high-quality fluorocarbon boards with indoor boards, squeezing unreasonable profits, thus causing serious discoloration and discoloration of the aluminum boards used in the project.

Opening and peeling of plastic board

The opening and peeling of the aluminum-plastic board is mainly due to improper selection of the binder. As an ideal binder for outdoor aluminum-plastic panel engineering, silicone glue has unique advantages. In the past, China's silicone rubber mainly relied on imports, and its value was discouraged by many people. Only those expensive curtain wall projects on high-rise buildings dare to ask questions. Now, China's Zhengzhou, Guangdong, Hangzhou and other places have successively put into production different types of silicone rubber, which has caused prices to plummet. Now, when buying aluminum-plastic panels, sellers will recommend that kind of special quick-drying glue. This kind of glue can be used indoors. If it is used outdoors with volatile climate, the board will open and peel off.

Deformation and bulging on the surface of aluminum-plastic board

If you walk around in any city, it is not difficult to find some projects that are deformed and bulging on the surface of aluminum-plastic panels. This phenomenon appears on small facade decoration projects, as well as on large high-rise buildings. In the past, there were such quality problems in construction. We thought that it was the quality of the plate itself. Later, after everyone's concentrated analysis, we found that the main problem was the base plate of the aluminum-plastic board, followed by aluminum-plastic. The quality of the board itself. Dealers often provide us with the construction process of aluminum-plastic panels, and the recommended base material is mainly high

Regardless of the current problems in the application of aluminum-plastic panel curtain walls, due to its inherent characteristics, aluminum-plastic panel curtain walls will still be the main force of aluminum-plate curtain walls. However, if the current problems are not correctly understood and corrected, it will bring immeasurable losses to the building curtain wall industry and the aluminum-plastic panel industry, and a large amount of hidden dangers will also remain in the building exterior walls in China. Analysis of the existing problems, we should start to correct from the following aspects.

The aluminum-plastic panel curtain wall is a common work of the aluminum-plastic panel industry and the building curtain wall industry, and it is also the crystallization of the management of the two industry competent departments. Propose effective methods to overcome and improve to eliminate the potential hidden dangers of construction insecurity.

As an aluminum-plastic panel product manufacturer, it should strictly produce aluminum-plastic panel exterior wall product standards, reject all unjust requirements, and block the formation of unqualified aluminum-plastic panel curtain wall products from the source of the material. In order to ensure the quality of special products for aluminum-plastic board exterior walls, it is very important to revise the national product standard of "aluminum-plastic composite board". For the production process of aluminum-plastic board products that are not suitable for the use of aluminum-plastic board curtain walls, such as the cold-pressed board process, the use should be prohibited.

At present, the quality of aluminum-plastic panel curtain wall products is not good, and another major reason for the poor image comes from the processing and installation control problems of curtain wall processing enterprises. Due to different system problems between the current standards and specifications in China and foreign standards and specifications, China does not yet have a strict and complete set of specifications and acceptance standards for the production and processing of aluminum-plastic panel curtain walls. An important link affecting the quality of aluminum-plastic panel curtain wall in China. Relevant authorities should formulate special specifications and acceptance standards suitable for the production, installation, and installation of composite aluminum panel curtain walls nationwide as soon as possible to regulate the behavior of the entire industry.

As the vitality of a product, its most important component is to have new development, which includes the development of new materials, new processes and new systems. In terms of materials, we can develop from how to further improve the stability, strength, heat resistance, heat insulation, and flame retardancy of aluminum-plastic board materials. From the production of curtain wall products, we can develop more new products and systems to meet the needs of different building structures. Such as the open aluminum-plastic panel curtain wall system, because its inner layer has a ventilation function, if properly designed, it can reduce the use of materials, and can improve all aspects of physical properties. It can also greatly reduce the wall caused by silicone structural adhesives. Surface smudges, and enhance the three-dimensional sense of the wall.

The unlimited price reduction, which causes unreasonable cost and infringes on the quality and function of the building curtain wall products, is absolutely not desirable. The end result is that the product image is damaged, and the engineering safety hazards are increased. In the end, the construction unit and The environment in which we live. We should appeal to investors and construction units to follow the final value and the laws of the market economy. We must not blindly focus on the word price. Instead, we should focus on the actual connotation of the product, such as the materials and technology used in the product. And manufacturing processes. The Chinese saying of "one cent for one cent" is the eternal truth.

Sustainable development of aluminum-plastic panel industry

For the healthy and sustainable development of the aluminum-plastic panel industry, we must be guided by a comprehensive, coordinated and sustainable scientific outlook on development, and do a good job in several aspects:

1. Be sure to work hard to improve product quality:

Product quality is the life of an enterprise and the foundation of industry development. We must change the tendency of focusing only on output and not on quality, and work hard on product quality.

2. Aluminum-plastic board production should be closely combined with market demand:

The main purpose of aluminum-plastic panels is to be used as building curtain wall and interior and exterior wall decoration. Therefore, the development of aluminum-plastic panels should be guided by the needs of the construction industry and the building decoration industry, and must be closely integrated with the building industry's building decoration industry. Development and common prosperity.

3. Actively play the role of the association:

The Association should establish a scientific development concept, enhance service functions, promote a sustainable, rapid, coordinated, and healthy development concept for the aluminum-plastic panel industry, give full play to the association's bridge, coordination, service, and self-discipline functions to create a good environment for the development of the aluminum-plastic panel industry.

4. Actively carry out technological innovation activities:

Promoting the technical progress of the aluminum-plastic panel industry Technology is the basis for the development of the aluminum-plastic panel industry. Only by continuous innovation and continuous progress in the technology can the aluminum-plastic panel industry last forever. As a new type of decoration materials, as a kind of organic-inorganic composite materials, aluminum-plastic panel still has continuous development and progress, although it has many excellent properties, because the market and demand are not static and technology is constantly improving.

Future development and outlook of aluminum-plastic panel curtain wall

Although there are many problems and difficulties in the aluminum-plastic panel curtain wall, this is only an inevitable process in the development of things. As long as we can know him and solve it as soon as possible, coupled with the advantages of aluminum-plastic panel curtain wall itself and the continuous development of new high-performance aluminum-plastic panel products and the application of new aluminum-plastic panel curtain wall system, we believe that the future of aluminum-plastic panel curtain wall should be broad As one of the building curtain wall products, it is irreplaceable and will continue to develop.

In addition, the export volume of aluminum-plastic board foreign trade has doubled in recent years. In order to avoid domestic project arrears and vicious competition with the industry, some manufacturers have made great efforts to open up foreign markets. At present, the regions with more exports are the CIS, Turkey, Africa, Southeast Asia and other regions, I believe that in the near future, aluminum-plastic panels produced in China will be used in engineering projects around the world.
