What Is the Current Status of China's Fluorocarbon Spraying Industry-Huachang Aluminum-Aluminum Profiles Supplier

With the rapid development of my country's construction industry, the emergence of the curtain wall industry in my country, aluminum profiles require a variety of colors, and the rise of the aluminum curtain wall industry, especially after recognizing that aluminum composite boards should not be used for high -rise buildings, my country's single -layer aluminum plates and aluminum aluminum are The amount of fluorocarbon spray coating of profiles has doubled from double the early 1990s. It turned out that there were only two oil plants (that is, fluorocarbon spraying professional factory) in Dongguan, Guangdong, and increased from my country to more than 30 since 1995. It was also supported. Coastal area. Not only did the professional spray plant, but some aluminum factories and curtain wall companies also invested in the construction of spraying factories, and still maintained the enterprise small and the entire department. There are only more than a dozen of more than ten officials, and there are obvious quality differences. Most of the new domestic fluorocarbon spraying equipment is designed by the United States, Germany, and Japan, and introduced computer software to introduce different types of electrostatic spray guns in various countries. There are suspension types with semi -suspension, suspension, that is, the front treatment and spraying of aluminum materials, and the solidification process. All aluminum materials are suspended. Clean, spray multiple times, curing until the spray is sprayed out of the product. This kind of automatic line is not much domestic, and the investment is large.

The other is the front treatment of aluminum plates in several grooves (such as an aluminum anode oxidized cleaning slot), chromiumization is also performed in the groove fluid, and then the aluminum is hung up. Complete the spraying cite sequence until the product is produced. Domestic hanging lines grow from 100 meters to up to 420 meters.

Generally, automatic fluorocarbon spray coating is mostly used for surface spraying on the aluminum plate. Because the length of the aluminum profile is 6 meters, it is difficult to hang and spray in the general automatic hanging type. A professional oil company said in Hong Kong to say a successful professional oil company. Recently, the longest 420 -meter -long full -automatic hanging fluorocarbon spraying wire has been built in the country. Six meters long aluminum profile, an annual spray area of 600,000 square meters, is also the largest and longest domestic, long -term, and automatic spray lines of the profile board. Any product, the advanced and backwardness of the equipment for manufacturing products is of course an important factors of the product quality, but often the equipment is too heavy. It seems that as long as the equipment is good, it can produce good products. There are no high -level technicians, skilled workers, only good equipment can also produce satisfactory products. Just like a driver with a low driving technology, driving a Mercedes -Benz car, there will also be an accident. Fluorocarbon spraying is strong. In the new spray line in China, regular debugging is enough for 2-3 months, but some debugging for half a year or even longer will not be adjusted. sex. Recently, the engineering chart has been cheap, so that a spray plant that has just been tested to spray nearly a thousand square meters of aluminum plates. As a result, the color difference is very large, the membrane is uneven, and only a small part can be used. When choosing a spray factory, not only depends not only on the advanced equipment, but also pay attention to the conditions and experience of technical personnel, that is, we must pay attention to the software. Aluminum materials have been treated for many years, all of which are anode oxidation. In order to achieve the solid oxidation film and luster of the color, the aluminum -oriented number of aluminum doors and windows and windows is made carefully at home and abroad. Finally, choose 6063 alloy (China is LD31). The characteristics of this alloy: the squeezing performance is easy to squeeze, the medium strength, the key is that it has good oxidation performance, a good decorative surface for aluminum doors and windows. This table is now: oxidation film is easy to generate and high degree of firmness. The thickness and color difference of the oxide film can be controlled, and the color adhesion is strong and shiny. But the oxidation color color is only white and bronze, and the color is monotonous.

Because the oxidation production process is to clean, oxidize, color and seal the hole in the oxidation groove fluid. The groove liquid is made from a variety of chemical elements. Each batch of aluminum is oxidized. The chemical components in the slot are changing. Therefore, the groove fluid is variable. It is not obvious to see the naked eye. If it is placed together in a large area, the color difference is very obvious. So the aluminum board curtain wall must not be treated with anode oxidation. Otherwise, the aluminum board curtain wall will be very ugly. The emergence of static spraying makes the surface treatment of the curtain wall aluminum plate solved, which not only makes the color differences smaller, but also can get a variety of colors of aluminum plate. Electricity spray scores: powder spray and fluorocarbon spraying, the raw materials of powder sprayed are: polyuretin, polysamine resin, epoxy resin, hydroxycol resin, and epoxy/polyester resin. Features of powder spraying: The spraying equipment is handmade, with automatic hanging type, simple construction, and coating thickness of more than 30 microns, resistance, friction resistance, corrosion, weather resistance, etc. Cheap. The biggest weakness of powder spraying is that the sun is afraid of the exposure of the sun. Long-term exposure will cause natural decoration. The color difference between the aluminum plate and the non-yang surface for a few years will be obvious. Generally, the obvious color difference is generated in 2-5 years. The name appears on the market is colorful aluminum profile. It is used for aluminum doors and windows, which is sprayed with ordinary aluminum -type powder foam. Increasing the color variety of aluminum doors and windows, but also enhance the corrosion resistance. In short: Fluorocarbon spraying in my country is a newer product. It is necessary to initially understand it to know it in order to correctly use it. I hope that some new spray lines in the country must improve the technology, summarize experience, and stabilize the development of fluorocarbon spraying business. There are more than 30 spray lines in China, and the annual spray area has exceeded 4 million square meters. For more than demand, do not repeat the fluorocarbon spraying line in a short time.
