Coating knowledge: introduction to fluorocarbon coating products

Core tip: the earliest "fluorocarbon coating" with a hundred years' service life of baotianxingzhou Yangtze River Bridge was actually born in 1938, which is the well-known Teflon coating of DuPont company, i.e polytetrafluoroethylene (PTFE), polytetrafluoroethylene (FEP) and other copolymers This kind of material has unique and excellent heat resistance (180 ℃ - 260 ℃), low temperature resistance (- 200 ℃), self lubrication and chemical stability It is known as "Teflon that is corrosion resistant and will never stick" The fluorocarbon paint is generally divided into trifluoroethylene and tetrafluorone, which have higher corrosion resistance Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Home of coatings news: the earliest "fluorocarbon coating" with a hundred years' service life of baotianxingzhou Yangtze River Bridge was actually born in 1938, which is the well-known Teflon coating of DuPont company, i.e polytetrafluoroethylene (PTFE), polytetrafluoroethylene (FEP) and other copolymers This kind of material has unique and excellent heat resistance (180 ℃ - 260 ℃), low temperature resistance (- 200 ℃), self lubrication and chemical stability It is known as "Teflon that is corrosion resistant and will never stick" The fluorocarbon paint is generally divided into trifluoroethylene and tetrafluorone, and the corrosion resistance of tetrafluorone is higher Due to the extremely high liquefying temperature and poor dispersion of pigments, it has been used only in non stick pot, medical, aviation and other fields, not in the construction field It was not until 1965 that pennwalt company in the United States successfully developed a building fluorocarbon coating based on polyvinylidene fluoride (PVDF) (trademark Kynar 500) The fluorocarbon coating realized commercialization, and people saw the application prospect of fluorocarbon coating in the construction field At present, tens of thousands of buildings in the world are shining under the protection of PVDF fluorocarbon coating Because this kind of coating is still baking coating, although the baking temperature is much lower than that of polytetrafluoroethylene, which is about 230 ℃, it can not be used on site and needs to be processed in the factory, which also restricts the further promotion of fluorocarbon coating It was not until 1982 that Japan's Asahi company developed FEVE, a kind of room temperature curing fluororesin which can dissolve in aromatic, lipid and ketone solvents at room temperature It overcomes the shortcomings of the original fluorocarbon coating which can not be cured at room temperature, realizes the ideal of coating fluorocarbon coating on the construction site, and greatly expands the application field of fluorocarbon coating Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
