The advantages and disadvantages of aluminum -plastic panel curtain wall

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. A vantaxe da limpeza máis sinxela da parede de cortina composta de aluminio, esta é a segunda razón pola que os deseñadores están dispostos a usar parede de cortina composta de aluminio -plástico. Non obstante, os edificios de alto nivel ou ultra -alto -ris utilizan paredes de cortina de placa de aluminio.

Creo que debería ser extremadamente prudente. Porque primeiro, a área de derrocamento de alto nivel adoita ser grande e o investimento implicado é moi grande. En segundo lugar, a maioría dos niveis altos están lonxe do chan e a maioría poden mirar lonxe das persoas.

As consecuencias só poden mirar un gran efecto, e é imposible ver o nivel de manualidades na superficie da parede exterior. Polo tanto, a necesidade da maioría das paredes exteriores empregando materiais tan elevados é cuestionable. En terceiro lugar, desde a perspectiva dos tempos antigos, non hai moitos exemplos de decorar a si mesmos decorándose só.

Cada material ten as súas propias características e vantaxes e non debemos medir as súas vantaxes e desvantaxes da cualificación e prezo do material. O proceso de instalación do taboleiro composto de aluminio ten as súas propias características. A súa tecnoloxía de construción ten actualmente tres tipos: método de instalación de apertura, instalación conxunta e método de instalación de pega. Sempre que se dominen os métodos de procesamento correctos e os procesos de construción, o rendemento e os indicadores de todos os aspectos poden cumprir as normas nacionais.

O estándar nacional de "placa composta de plástico de aluminio" foi lanzada en 1999. A liberación e implementación de estándares xogaron un papel importante para garantir a calidade do produto, regular o comportamento do mercado e guiar o saudable desenvolvemento da industria. Ata o de agora, os fabricantes desenvolveron rapidamente a máis de 100, cunha produción anual de máis de 500 millóns de metros cadrados.

Os produtos son amplamente empregados en moitas industrias como paredes de cortinas, decoración interior e exterior, publicidade, automóbiles, entretemento e negocios. Nos últimos anos, a produción e aplicación do taboleiro composto de aluminio desenvolveuse rapidamente. Co desenvolvemento continuo e a mellora da tecnoloxía de produción, os equipos, a xestión e os niveis de aplicación, as placas compostas de aluminio convertéronse en industrias cada vez máis importantes. Moi gran atención de todos os ámbitos. Especialmente como un novo tipo de material de parede de cortina, recibiu cada vez máis atención de todos os ámbitos da vida.

Agora, China converteuse no centro de fabricación e aplicación de placas de plástico de aluminio máis grande do mundo e estableceu unha asociación de materiais compostos de aluminio e un centro de inspección de material composto de aluminio en aluminio.
