The use of fluorocarbon coatings
The application of fluorocarbon coatings in the field of steel first appeared on color steel plates and was installed on the top of workshops and warehouses. Because of its durability, easy installation and gorgeous colors, it quickly became popular around the world. The global giant in the field of steel structure construction and products, Butler, almost all of the color steel plate business and the steel structure business of buildings and bridges she undertakes use fluorocarbon coatings. The roof of Shanghai Pudong International Airport is painted with fluorocarbon paint.
In the field of road and bridge construction, the anti-corrosion requirements for all steels are very high. According to the statistics of some countries in the world, the total corrosion loss can account for 2%-4% of the gross national economic output (GDP) every year. The loss related to the corrosion of steel bars in the United States can account for 40% of the total corrosion loss. The corrosion damage of bridges alone accounts for the total 20% of corrosion loss. Therefore, 90% of the key bridges designed or renovated after 2000 are designated with fluorocarbon coatings for protection.
In the field of construction, especially high-end buildings and factory buildings, steel structures have begun to be widely used. In order to maintain long-term safety and beauty, and reduce the cost of cleaning and maintenance, most designers specify the use of fluorocarbon coatings on exterior walls and steel structure surfaces when designing. Successful cases include: Shanghai Science and Technology City, Pudong International Airport, Hongkou Stadium, Shanghai Hongqiao Airport.
In the field of steel structures for overhead antennas and TV towers, fluorocarbon coatings are still indispensable. The annual direct cost of steel tower and mast renewal in my country is more than 10 million yuan. The annual average metal protection cost of the central radio station accounts for about 10% of the total maintenance cost. Individual projects use weathering steel with fluorocarbon coatings, and the coating cost is about 10%. It accounts for 10%-25% of the cost of the steel structure, and the maintenance cost is saved by about 10% every year. The 10-year savings would allow for the construction of another tower of the same height.
concrete
The application of fluorocarbon coatings on concrete is mainly reflected in the exterior walls of buildings. The exterior walls of buildings in developed countries such as the United States, Europe, and Japan have gradually abandoned decorative materials such as tiles and mosaics, and more than 80% of them are decorated with coatings. Among them, the excellent comprehensive performance and performance-price ratio of fluorocarbon coatings make it have an unparalleled competitive advantage in ultra-high buildings, landmark buildings, key projects, etc. With the development and application of water-based fluorocarbon coatings, it can be sprayed , and can also be mixed, which greatly reduces the cost of construction. This is also the main growth point of the fluorocarbon coatings market. In the field of building exterior walls in my country, the use rate of coatings is very low, only 10%, and the use of fluorocarbon coatings is even less. With the restrictions on building materials such as ceramic tiles, mosaics, and glass curtain walls in national regulations, the share of coatings in the construction market will rise sharply, and it is expected that by 2015, it will reach more than 60%. Among them, fluorocarbon coatings have unique advantages in large buildings, ultra-high buildings, and landmark buildings. The buildings that have used fluorocarbon coatings on the exterior walls include: Shanghai Seaside Defense Checkpoint, Oriental Art Center, Zhengda Plaza, Shenzhen Shekou Science and Technology Building , Changde Cigarette Factory and so on.
organic material
In the 1990s, it was impossible for fluorocarbon coatings to be applied to organic materials such as plastic-steel profiles, FRP, and plexiglass. Because organic materials cannot withstand the baking temperature of 230-250 °C, it was not until the beginning of this century that fluorocarbon coatings began to be used on organic materials with the advent of room temperature-curable fluorocarbon coatings.
Aluminum alloy
In the past, the coating of domestic aluminum alloys and aluminum-plastic panels relied on PVDF fluorocarbon coatings imported from abroad. With the advancement of domestic technology, domestic PVDF, medium and low temperature, and room temperature fluorocarbon coatings have gradually replaced imported coatings.
Other areas
Fluorocarbon coatings have excellent weather resistance, friction resistance, wiping resistance, stain resistance, acid resistance, alkali resistance, oil repellency, water repellency and other properties.
Fluorocarbon coatings are divided into water-based and oil-based; they are also divided into civil and industrial. Fluorocarbon coatings can be used on cars, but the hardness of fluorocarbon coatings is not high enough, only 4-6H.
Auto parts, outdoor home appliance shells, hardware accessories, etc., are also using fluorocarbon coatings in large quantities to increase the wear resistance, lubricity, cushioning and service life of the parts themselves. Shipbuilding is considered another huge market for fluorocarbon coatings.
The application of fluorocarbon coatings in foreign countries has been quite common, which is related to their economic strength, coating penetration rate, use experience, quality concept and other factors. The application and sales volume of domestic fluorocarbon coatings are still at a relatively low level. People don’t know enough about its performance and usage. With the advancement of fluorocarbon coating technology and the improvement of construction application technology, the excellent performance-price ratio of fluorocarbon coatings will make it more and more competitive in various fields.
