As an emerging architectural decoration material, aluminum veneer is gradually becoming the preferred material for modern architectural design with its unique properties and wide application fields. In this paper, the material characteristics, processing technology, application advantages and market prospects of aluminum veneer will be elaborated.
Material characteristics
Aluminum veneer is a new type of building decoration material, which is made of aluminum alloy sheet as base material, after pretreatment such as chromium, and then processed by fluorocarbon spraying technology. Its main features include:
Light and high strength: Compared with traditional materials such as stone and glass, aluminum veneer has a lighter weight, but at the same time has good structural strength and load-bearing performance. For example, the 3.0mm thick aluminum plate weighs only 8kg per square meter, but its tensile strength can reach 100-280N/mm2, ensuring the safety of the building.
Corrosion resistance and oxidation resistance: After special surface treatment, aluminum veneer forms a dense oxide layer, which can effectively resist the erosion of acid and alkali exhaust gas and bad weather conditions, and extend the service life. PVDF fluorocarbon paint with kynar-500 and hylur500 as the base material can ensure that the aluminum veneer will not fade in 25 years.
Good process: Aluminum veneer adopts the process of first processing and then painting, which can be processed into a variety of complex geometric shapes such as plane, arc and sphere, to meet the complex modeling requirements of buildings. At the same time, the advanced electrostatic spraying technology makes the adhesion between the paint and the aluminum plate uniform, diverse colors, large choice space.
Convenient installation: The aluminum veneer is formed in the factory, and the construction site does not need to be cut, only needs to be fixed on the skeleton, which greatly shortens the construction period and reduces the construction cost.
Environmentally friendly recyclable: Aluminum veneer can be 100% recycled and reused, with high recycling residual value, in line with modern environmental protection concepts.
Processing technology
The processing process of aluminum veneer includes the process design stage, opening, punching, punching, grooving, bending, welding, corner coding and backbar, polishing and spraying steps. Among them, the spraying process is particularly critical, mainly divided into powder spraying and fluorocarbon spraying two. Fluorocarbon spraying has become the most widely used surface treatment method for its excellent weather resistance and decoration.
Application advantage
Because of its unique properties, aluminum veneer has a wide range of application advantages in the field of architectural decoration:
Diversified appearance effect: Aluminum veneer can be bent, stretched, stamped and other processing according to design requirements to achieve diversified appearance effect and meet personalized architectural design requirements. At the same time, the rich color choice also enables it to adapt to the needs of different architectural styles.
Good weather resistance and durability: fluorocarbon spraying technology makes the surface of aluminum veneer form a dense protective film, which can effectively resist the erosion of harsh environmental factors such as ultraviolet light and acid rain, and extend the service life.
Easy to clean and maintain: the non-adhesion of fluorine coating film makes it difficult to attach contaminants to the surface of aluminum veneer, which is easy to clean and maintain and reduces the later maintenance cost.
Fire safety: Aluminum veneer contains non-combustible metal aluminum material, with excellent fire performance, effectively reduce the risk of fire, increase the safety of the building.
Market prospect
With the continuous development and innovation of the construction industry, the application prospect of aluminum veneer in the field of building exterior wall decoration will be more and more broad. Its characteristics of light and high strength, corrosion resistance and oxidation resistance, strong plasticity, easy installation and maintenance make aluminum veneer the preferred material for green environmental protection. In the future, aluminum veneer is expected to continue to promote the innovation of architectural design, and inject a new fashion and era atmosphere into modern architecture.
In summary, aluminum veneer with its unique performance and wide application fields, is gradually becoming a high-quality choice for modern architectural design. With the continuous progress of science and technology and the improvement of people's environmental awareness, the market prospect of aluminum veneer will be broader.
