Hlcaluminium -aluminium composite Panels Manufacturers
In recent years, with the rapid economic development, the decoration standards of the construction units have also risen. Some newer building exterior walls are becoming increasingly popular with some high -end decoration materials. It seems that it is not enough to display its grade without the curtain wall. A few years ago, it was popular glass and natural stone curtain walls.
At present, it is mainly used for some public buildings, and there are also a few residential areas that are used for high -end routes. Because the use of aluminum -plastic composite boards for high -rise buildings has always been left -handed, aluminum -plastic composite board has become the latest hot topic in the industry since its birth. One opinion is that the aluminum -plastic composite board curtain wall should be used less or cautious.
The use of aluminum -plastic composite plates (ie, aluminum -plastic plates) as high -rise buildings will become "air killer" or "invisible killer", which is extremely dangerous. Those who hold this opinion believe that its disadvantages are four: First, the structure of the aluminum -plastic composite board is generally three layers, and the two sides of the outside are 0.1 to 0.5mm thick aluminum layer. Polyethylene) and other polymer materials are bonded with tree vinegar glue. The core materials and glue contain toxic ingredients, and the fire prevention, weather resistance, durability, anti -aging and other properties are poor. It will release a poisonous gas that is harmful to human health; the second is that the compound strength is not high, and it is easy to break when the corner curved surface. When the partial heating is heated, the core material will expand and cause the surface aluminum plate to deform and fall off. In addition, its thermal expansion coefficient is generally larger than the keel and building. Frequent sudden drum phenomenon is often lost to affect the beauty; the third is that it is generally shared with a lightning protection device with the building subject during installation. Lightning attack; Fourth, the strength of its wind pressure is not high due to the strength of the material itself. At present, high -rise buildings in advanced countries abroad have rarely adopted aluminum -plastic composite boards as curtain walls, and they have switched to single -layer aluminum plates with relatively high security and reliability.
Another opinion is that the aluminum -plastic composite plate is characterized by light weight, proper steel, can be reduced and soundproof, and its decorative effect is better. The second processing is comparable to the aluminum plate, but the cost is much low. Those who support this view believe that after these years of development, the aluminum -plastic composite board has gradually matured technology. Before the material is leaving the factory, it is generally processed by corrosion resistance, weather resistance, collision resistance, folding, pressure resistance, etc. Safety and reliability. The use of aluminum -plastic composite boards on high -rise buildings is used as curtain walls. Although the requirements of wind resistance and pressure are high, the size of the pressure resistance is not only related to the quality and performance of the wall material itself, but also involves the size of the installation size, the length and width ratio of the plate, and the keel configuration of the keel configuration. The degree of denseness and so on.
If strictly follow the requirements of the construction specifications, the aluminum -plastic composite board that is generally composed of quality indicators can be used as a curtain wall for high -rise buildings. In addition, the current techniques and measures for lightning protection are relatively mature. High -rise buildings are generally thoughtful in this regard. As for the aluminum -plastic composite board curtain wall, it is damaged by lightning strikes. There are any precedents outside. Therefore, it can be widely used in the exterior wall decoration of high -rise buildings.
At present, it is more difficult for the aluminum -plastic composite curtain wall to fully obtain consensus in the industry, because "the public says that the public is reasonable, and the mother -in -law is reasonable." However, ordinary citizens, aluminum -plastic composite board manufacturers, and owners of high -rise buildings hope to give aluminum -plastic composite board curtain walls, because citizens and owners are most concerned about the safety they use, and the company is concerned about the market's market. Essence The production of aluminum -plastic composite boards in my country began in the 1990s and has developed rapidly. In just a few years, aluminum -plastic composite board has become the third largest curtain wall decoration material in my country after stone and glass.
At present, my country has become the country with the largest use and export volume in the world, with an annual output of 200 million square meters and an output value of nearly 20 billion yuan. However, counterfeit and inferiority makes the aluminum -plastic composite board facing a disaster. Standard aluminum plastic plates are divided into two types: inner and outer walls. The inner hanging consists of two layers of 0.12 mm aluminum plates and PVC. The thickness of the aluminum -plastic composite plate on the outer wall should reach 4 mm. PVC material composition, the paint surface uses anti -aging fluorocarbon paint.
But now many products on the market are only 0.005 mm thick, and even garbage in plastic for core materials. According to international standards, the reasonable price of the outer wall aluminum plastic composite board is 200 to 220 yuan per square meter, but the lowest price on the market has been sold to 50-60 yuan per square meter. Low -priced products accompanied by inferior products, which seriously affected the reputation of aluminum -plastic composite boards, causing some experts to lose confidence in it and solidify their opposition by some people.
Behind the prosperous market phenomenon, some counterfeit and inferior and cut corners are constantly organized, and the phenomenon of wrong application of aluminum -plastic plates also occurs from time to time. Some use the inner wall plate to impersonate the outer wall plate, some use ordinary decorations as a thin plate as a curtain wall board, some use ordinary plates to impersonate fluorica carbon plates, etc. Some users cannot understand the aluminum -plastic composite board. Correctly apply aluminum -plastic boards and misunderstand aluminum plastic boards. The original national standard of "Aluminum Plastic Composite Plate" was formulated in the early stage of the development of aluminum -plastic composite boards. In the standard, the understanding of aluminum -plastic composite board naturally has a certain historical limitations.
For example, in the original "Aluminum Plastic Composite Board" standard, the aluminum -plastic composite plate was simply divided into the inner wall board and the outer wall board. Through the development of applications and markets over the past few years, the application of aluminum -plastic composite boards has become more detailed and clear. Therefore, the amendment to the standards in a timely manner will help better guide production and application, guide the correct development of the industry, and better meet the needs of society.
As far as the designer is concerned, in addition to ensuring the safety of its use, the aluminum -plastic composite curtain wall is mainly considered from two aspects of building shape and later maintenance of the building. Because the aluminum plate has a large single block, strong plasticity, excellent manufacturing process, the perception of the surface metal texture is more characteristic. It is very modern and has a lot of color varieties. Therefore, it can better reflect the designer's design ideas. one. And the materials we usually use usually changes faster over time, or it is difficult to clean up after dirty.
These have undoubtedly increased the difficulty of maintenance and maintenance, resulting in the oldest after three or five years. The advantage of the easier cleaning of aluminum -plastic composite curtain wall This is the second reason why designers are willing to use aluminum -plastic composite board curtain wall. However, high -rise or ultra -high -rise buildings use aluminum board curtain walls.
I think it should be extremely cautious. Because first, the high -level overthrow area is usually large, and the investment involved is very large. Second, most of the high levels are far from the ground, and most of them can look far away from people.
The consequences can only look at a big effect, and it is impossible to see the level of crafts on the surface of the exterior wall. Therefore, the necessity of most exterior walls using such high -end materials is questionable. Third, from the perspective of ancient times, there are not many examples of decorating themselves by decorating themselves alone.
Each material has its own characteristics and advantages, and we should not measure its advantages and disadvantages from the grade and price of the material. The installation process of aluminum -plastic composite board has its own characteristics. Its construction technology currently has three types: opening installation method, joint installation and paste installation method. As long as the correct processing methods and construction processes are mastered, the performance and indicators of all aspects can meet national standards.
The national standard of "Aluminum Plastic Composite Plate" was released in 1999. The release and implementation of standards have played an important role in ensuring product quality, regulating market behavior, and guiding the healthy development of the industry. Until now, manufacturers have rapidly developed to more than 100, with an annual output of more than 500 million square meters.
Products are widely used in many industries such as curtain walls, indoor and outdoor decoration, advertising, automobiles, entertainment, and business. In recent years, the production and application of aluminum -plastic composite board has developed rapidly. With the continuous development and improvement of production technology, equipment, management, and application levels, aluminum -plastic composite boards have become more and more important industries. Very great attention from all walks of life. Especially as a new type of curtain wall material, it has received more and more attention from all walks of life.
Now, China has become the world's largest aluminum -plastic composite board manufacturing and application center, and has established an aluminum -plastic composite material association and aluminum -plastic composite material inspection center.
