In the Process of Continuous Development of the Construction Industry, What Are the Materials Used in the Curtain Wall? -WJW Aluminum Supplier Aluminum

Curtain wall material:

The classification material of curtain wall materials is a material basis for ensuring the quality and safety of curtain walls. The materials used in the curtain wall are basically available in four types. That is, skeleton materials, plates, structural bonding, sealing filling materials, hardware accessories, etc. There are two main skeleton materials: aluminum profile and steel. This board mainly includes glass, aluminum plates, stone, stainless steel plates, ceramic plates, thousands of thoughts, color steel plates, solar boards, etc. Structural bonding and sealing filling materials mainly include organic silicon structure adhesives, meteorological sealing, double -sided tape, sealing strips, foam sticks, insulation rock wool, etc. Hardware attachments mainly include opening accessories, embedded parts, rotary connectors, connectors, etc.

2. Basic requirements for curtain wall materials

1 Most of the domestic curtain wall materials in China meet the corresponding specifications and standards, and most of them have national or industry standards. However, due to the differences in production technology and management level, the quality of similar materials in cities is also very different due to the different quality of manufacturers. "The curtain wall, as the outer wall of the building, does not bear the load of the main structure, it is on the outer surface of the building. In addition to its own weight, it is also affected by the effects of wind load, earthquake, and temperature. It must be safe and reliable. The materials used in the curtain wall shall meet the quality indicators of national standards or industry standards. A few materials have no national or industry standards for the time being. According to the requirements of similar foreign product standards, manufacturers formulate corporate standards as product quality control. Basis. In short, the use of unqualified materials must be strictly prohibited, and a factory certificate must be.

2 The curtain wall with weather resistance and durability is located on the surface of the building, and it is often affected by adverse factors such as the natural environment such as the sun, rain, and sand. Therefore, curtain wall materials must have sufficient weather and durability. It has the functions of wind and rain, sun protection, theft, anti -collision, insulation and other functions. Therefore, in addition to stainless steel and weather -resistant steel, effective anti -corrosion measures such as hot -dip galvanized, inorganic zinc -rich coating should be used to deal with steel. Aluminum alloy materials should be performed on the surface anode oxidation, electric swimming, powder spraying, or spraying fluorocarbon to ensure the durability of the curtain wall.

3 The unsatisfactory and non -flammable curtain wall, whether in processing, installation and construction, after delivery, it is very important for preventing fires from preventing fires. Therefore, non -combustible materials and non -combustible materials should be used as much as possible, but there are many materials at home and abroad, such as double -sided tapes and filling rods, all of which are flammable materials. Therefore, pay more attention in installation and construction and take fire prevention measures.

Two skeleton materials

There are two main types of skeleton materials on the curtain wall, one is aluminum alloy profile, and the other is steel. It is mainly used to make the screen frame frame (also known as curtain wall keel) and surface material board. Generally speaking, aluminum alloy profile is a keel and auxiliary framework for glass and aluminum -sheet curtain walls, while steel is a keel on the lack wall.
