The curtain wall of the building has developed rapidly with the emergence of high-rise buildings and a lot of demand. Throughout the development of the century-old building curtain wall, as early as the first half of the 21st century, the curtain wall gradually appeared in people's vision. The emergence of new technologies, new industries, new structures, and new materials led the curtain wall to new reform step by step.
Nowadays, in addition to transforming people’s living environment, architectural design also has a certain degree of influence on the spiritual level. The accumulation of years of individualized expression of architectural art has brought people visual and spiritual enjoyment. But in addition to its functional shape, the architectural image itself also includes the texture and effectiveness of the building materials.
Metal building material curtain wall materials have been used for decades, and materials that have been retained so far include aluminum veneer, aluminum-plastic composite board and aluminum honeycomb board. The most commonly used is aluminum veneer, followed by aluminum-plastic composite panels, and finally aluminum honeycomb panels.
1. Aluminum Veneer
The high-quality aluminum alloy panel is used as the base material, and the advanced numerical control bending technology is used to ensure that the plate can be flat and not deformed after processing, and has excellent external force resistance during installation. The surface coating is made of PVDF coating, which ensures that the surface is evenly polished, can maintain no fading, no chalking, and has a long service life. The aluminum veneer also has excellent characteristics such as resistance to cold and heat, oxidation, ultraviolet radiation, and corrosion. It is the most commonly used curtain wall construction material in China.
2. Aluminum-plastic Composite Board
The aluminum-plastic composite board was invented by Germany in the late 1960s and early 1970s. It uses chemically treated coated aluminum plate as the surface layer material and polyethylene plastic as the core material. It is a composite processed by using special aluminum-plastic plate production equipment. material. Due to the characteristics of the material, it has the excellent characteristics of optional color diversity, convenient construction, and easy processing. The low cost made it quickly gain people's favor after it was introduced into the country.
3. Aluminum Honeycomb Panel
The panel is mainly made of aluminum alloy aluminum plate or high-manganese alloy aluminum plate as the base material. It adopts hot-press forming technology and sliding mounting buckle system to ensure that it will not cause structural deformation during heat shrinking and expansion. It has good performance in scratch, acid resistance and anti-corrosion. Because aluminum honeycomb material has excellent properties such as high wind pressure resistance, shock absorption, sound insulation and heat insulation, the curtain wall material made of it has the advantages of light weight, high strength and high rigidity. It is also widely used in high-rise building exterior wall decoration in China.
