Then the use of fluorocarbon spraying technology, processing of the formation of building decoration materials. Fluorocarbon coatings mainly refer to polyvinylidene fluoride resin (kanar500), primer, topcoat and varnish. The spraying process is generally divided into two coatings. The three-coated aluminum veneer refers to the building decoration materials which are processed by fluorocarbon spraying technology after being treated with chromium and so on. Fluorocarbon coatings mainly refer to polyvinylidene fluoride resin (kanar500), primer, topcoat and varnish. Spraying process is generally divided into two coating, three or four coating. Fluorocarbon coating has excellent corrosion resistance and weather resistance, can be resistant to acid rain, salt fog and a variety of air pollutants, excellent resistance to cold and heat, can resist strong ultraviolet radiation, can maintain long-term non-fading, non-powdering, long service life.
1, light weight, good steel, high strength 3.0mm thick aluminum plate weight 8 kg per square plate, tensile strength 100-280n/mm2
2, good durability and corrosion resistance. Pvdf fluorocarbon paint based on kynar-500,hylur500 can be used for 25 years without fading.
3, the craftsmanship is good. The aluminum plate can be machined into a variety of complex geometric shapes, such as plane, arc, sphere and so on.
4, the coating is uniform and colorful. Advanced electrostatic spraying technology makes the adhesion between paint and aluminum plate uniform and consistent, the color is diverse, and the selection space is large.
5, not easy to defile, easy to clean and maintain. The non-adhesion of fluorine coating film makes it difficult to attach pollutants to the surface and has good cleanliness.
6, the installation and construction is convenient and fast. Aluminum plate is formed in the factory, the construction site does not need to be cut, fixed on the skeleton can be.
7. it can be recycled and recycled, which is beneficial to environmental protection. Aluminum plate can be 100% recovery, different from glass, stone, ceramics, aluminum plastic board and other decorative materials, recovery residual value is high.
Metal panel curtain wall has been used for decades, including aluminum veneer, aluminum-plastic composite board and aluminum honeycomb board. Of these three materials, the most commonly used are aluminum veneer and aluminum plastic board. Aluminum veneer first appeared, and then in the late 1960s and early 1970s, aluminum-plastic composite plate was invented in Germany and became popular all over the world. What is the difference between aluminum plastic board and aluminum veneer? Here I would like to make a simple comparison between the two materials:
Materials and Cost：
Aluminum veneer generally adopts 2-4mm thick aa1100 pure aluminum plate or aa3003 and other high quality aluminum alloy plate, 2.5mm thick aa3003 aluminum alloy plate is generally used in China, aluminum-plastic composite plate generally adopts 3-4mm three-layer structure, including upper and lower 0.5mm clamping pvc or pe.. We can see from the material that the cost of aluminum-plastic composite board is certainly much lower than that of aluminum veneer. The market is about 4mm thick composite plate price is more than 120 yuan / square lower than 2.5mm thick aluminum veneer price, a ten thousand square project, the use of aluminum plastic board than the use of aluminum veneer cost of 1.2 million yuan.
There are two kinds of aluminum veneer in the world: fluorocarbon sprayed aluminum veneer and roll coating. There is no roller coating production line in China for the time being, so the processing process of veneer here is mainly about fluorocarbon spraying production. Spray aluminum veneer is divided into two steps: the first step is sheet metal processing. This process is mainly through cutting, folding, arc bending, welding, grinding and other procedures to process the aluminum veneer into the shape and size needed for construction. The second step is spraying. Spraying is spraying paint on processed sheet metal. Spraying is divided into two kinds, one is manual spraying, the other is machine spraying. Artificial spraying is a dangerous job, because the volatile and toxic process of paint is easy to cause chronic benzene series poisoning, which seriously affects people's health. One advantage of artificial spraying is that aluminum plastic board can be used in environmental protection and safety.
