Fluoro-Coatings Should Go Out of the Misunderstanding of "homogenization"
- Interview with "China Anti-corrosion Master" Liu Weicheng
In recent years, due to the general rise in chemical raw materials, the domestic fluorine coating industry has entered the era of meager profits, coupled with China's fluoroplastic coating species is too single, the vicious competition among peers makes the fluororesin coating market chaos. Faced with this extremely unfavorable trend of development, Liu Weicheng, chief engineer of Dalian Zhenbang Fluor Coatings Co., Ltd., who has won the title of “China Antiseptic Masterâ€, believes that for the development of China's fluorine coating industry, it must go out of the “homogenization†misunderstanding.
Fluorine paint is also called fluorocarbon paint. Because of the extremely stable chemical properties of fluorocarbon bonds of fluorine materials, fluorocarbon paint has excellent performance. Practice has proved that under the conditions of increasingly serious environmental pollution, the durability of fluorine coatings can be up to 20 years outside the house, and the chemical resistance can reach more than 1,500 hours. Some urban landmarks in the United States use aluminum curtain wall panels treated with fluorocarbon paint. The paint film has not changed for 30 years. The excellent performance of fluorocarbon paint brings a qualitative leap for the development of the coating industry.
According to Liu Weicheng, China's fluorocoating industry started late, but it has developed rapidly. At present, there are two major series of products. First, thermoplastic vinylidene fluoride coatings for high-temperature baking of aluminum curtain wall panels, and second, solvent-soluble, room-temperature curing FEVE. Fluorine resin coating. Among them, FEVE fluororesin coating can be cured at room temperature and can also be formed by baking at low temperature. It is the leading product in fluorine coatings in China. At present, there are more than 70 companies with production capacity of FEVE fluororesin coatings in China, and the annual production capacity of fluororesin coatings has reached nearly 20,000 tons in less than 5 years, and the total expansion is 2O times. In contrast, the domestic fluorine coating market is relatively slow. The annual sales volume is only about 2,000 tons. The fluorine coating production capacity has greatly exceeded the domestic market demand. At the same time, the development of FEVE fluorine resin coating market in China is chaotic. The homogeneity of products is serious and the market is fiercely competitive. Various manufacturers lack differentiated products to open up the market.
In view of the current status of domestic fluorine coatings, Liu Weicheng suggested that, first, companies should use some new monomers for copolymerization modification or find some new polymerization of fluorine-containing monomers to prepare new types of fluorine resin coatings, improve the performance of fluorine coatings and open up new applications, The use of material innovation to improve the industrial structure; Second, the product should be functional, differentiated, marginal development, in the existing fluorocarbon composite insulation board, aluminum powder special fluorine resin and fluorine resin for steel structure, fluorine resin for coiled material basis The development of architectural engineering, corrosion protection of steel structures, and metal surface decoration are particularly applicable to new products such as the Qinghai-Tibet Plateau where the temperature difference between day and night is large, the radiation intensity is high, the climate is dry and other harsh natural conditions; in addition, the thermoplastic vinylidene fluoride must be accelerated. The research of ethylene and water-based fluororesin coatings breaks through the limited application difficulties of thermoplastic vinylidene fluoride coatings during the use process, and seizes market opportunities.
