1、 Introduction to column wrapped aluminum veneer
Currently, fluorocarbon spraying is available Aluminum veneer And roller coating, but there is no roller coating in China production line Therefore, the processing of veneer here is mainly about fluorocarbon spraying production. Spray production Aluminum veneer There are two steps: Sheet metal processing 。
This process is mainly through Flat After cutting, flanging, arc bending, welding, polishing and other processes Aluminum veneer Processed into the shape and size required for construction.
The second step is spraying. Spraying refers to spraying on processed sheet metal paint 。 There are two kinds of spraying: manual spraying and machine spraying. Generally, machine spraying is only suitable for regular plates, but it is seldom used in actual use. Most domestic manufacturers use manual spraying.
Manual spraying is a dangerous job, because the volatility and toxicity of paint are relatively strong, which is easy to cause chronic benzene A series of poisoning seriously affects people's health.
One of the advantages of manual spraying is that the color can be selected regardless of the amount, while it is recommended that the roll coating of aluminum plastic plate can be processed only after reaching a certain amount. Compared with the processing of aluminum plastic plate Aluminum veneer It is more complicated, mainly including four processes of formation, coating, compounding and trimming, which are all automatic production except trimming.
II Specification of column wrapped aluminum veneer
The structure of aluminum veneer is mainly composed of panel, stiffener, corner code and other components. The size of formed large workpiece can be 8000mm × 1800mm (L × W)
The coating adopts well-known coatings such as PPG of the United States, Valspar of the United States, AkzoNobel of the Netherlands, KCC of the Republic of Korea, etc. The coating is divided into two layers of coating, one layer of baking, three layers of baking, and the coating performance meets the AAMA2605-98 standard of AAMA (American Building Manufacturers Association) and ASCA (American Building Spraying Association).
Normal thickness: 1.5mm, 2.0mm, 2.5mm, 3.0mm.
Common specifications: 600 * 600mm, 600 * 1200mm
III Wrapped column Features of aluminum veneer
1. It is characterized by light weight, good rigidity and high strength, 3.0mm thick aluminum plate weighs 8kg per square plate, and tensile strength is 100-280n/mm2
2. Good weather resistance and corrosion resistance. Pvdf fluorocarbon paint based on kynar-500 and hydrar500 can make the surface of aluminum veneer fade for 50 years.
3. Good processability. The aluminum plate can be processed into various complex geometric shapes such as plane, arc and sphere by the process of processing before painting.
4. The coating is uniform and colorful. The electrostatic spraying technology makes the adhesion between the paint and the aluminum plate uniform, with various colors and large selection space.
5. It is not easy to stain and is convenient for cleaning and maintenance. The non adhesion of the fluorine coating film makes it difficult to attach pollutants to the surface, and has better self-cleaning property.
6. The installation construction is convenient and fast. The aluminum plate is formed in the factory, and can be fixed on the skeleton without cutting on the construction site.
7. It can be recycled, which is beneficial to environmental protection. The aluminum plate can be recycled, which is different from glass, stone, ceramics, aluminum plastic plate and other decorative materials, with high recycling residual value.
IV Wrapped column Advantages of aluminum veneer
As a new type of exterior wall decoration material, it has many good characteristics: rich colors, which can meet the color requirements of modern buildings.
PVDF fluorocarbon coating is selected as the surface coating, with good color stability and fastness; Weather resistance, anti-aging, long-term UV resistance, resistance to wind, acid rain, industrial waste gas and other erosion.
In addition, the fluorocarbon coating surface is difficult to attach pollutants, which can be kept smooth and clean for a long time, easy to clean and maintain, light weight, high strength, and strong wind pressure resistance.
V Wrapped column Aluminum veneer installation
（1） Setting out: fix the skeleton and snap its position to the base course. The skeleton is fixed on the main structure, and the quality of the main structure is checked before setting out
（2） Fix the connector of the skeleton: weld the connector on the column of the main structure to fix the skeleton.
（3） Fixed skeleton: the skeleton is pre treated with anti-corrosion treatment. The installation framework shall be accurately positioned and firmly connected. Check the center line and surface elevation after installation. In order to ensure the installation accuracy of the plate, it is advisable to use a theodolite to run through the crossbar mullion members. The deformation joint, settlement joint and variable section shall be properly treated to meet the use requirements.
（4） Installation of aluminum plate: the installation and fixation of aluminum plate shall be firm, reliable, simple and easy.
1. The gap between plates shall be treated internally to make it flat and smooth.
2. After the aluminum plate is installed, the parts easy to be polluted shall be covered with plastic film or other materials for protection.
VI Wrapped column Use of aluminum veneer
It is suitable for decoration of interior and exterior walls of various buildings, lobby facades, column decorations, elevated corridors, pedestrian overpasses, elevator edging, balcony packaging, advertising signs, indoor profiled ceiling, etc.
Building exterior walls, beams and columns, balconies, awnings, airports, stations, conference halls, opera houses, stadiums, reception halls and other high-rise buildings.
