Valve plate spraying ECTFE refers to the technology of applying ethylene chlorotrifluoroethylene copolymer (ECTFE) coating on the surface of the valve core component valve plate through professional spraying process, with the aim of improving the comprehensive performance of the valve plate. The following briefly introduces the core advantages, key processes, and main applications:
1. Core advantage: The important aspect of this technology is its strong corrosion resistance, which can resist the erosion of strong corrosive media such as strong acids, strong alkalis, and various organic solvents, and can cope with harsh media environments in industries such as chemical engineering; The coating also has low friction characteristics, which can reduce the wear between the valve plate and the valve seat during opening and closing, and improve the flexibility of valve opening and closing; At the same time, it is resistant to high temperatures and has good mechanical strength. It can maintain stability under certain temperature and pressure fluctuations, and is not prone to coating cracking or peeling. It can also reduce the adhesion of the medium on the surface of the valve plate through anti adhesion, reducing the difficulty of cleaning and maintenance.
2. Key process: Firstly, the surface of the valve plate needs to be pre treated with sandblasting, polishing, etc., to remove oil and impurities and improve surface roughness, ensuring coating adhesion; Next, primer treatment can be carried out according to the requirements, and then ECTFE powder can be loaded into a professional spray gun. After adjusting the parameters, it can be evenly sprayed on the surface of the valve plate; Put the sprayed valve plate into the curing oven, control the temperature and time according to the material requirements to complete the curing. After curing, check the uniformity of the coating and repair the defective parts. However, this process is more suitable for conductor substrates, and for valve plates with complex shapes, manual spraying may be required to avoid uneven coating.
3. Main applications: Valve equipment commonly used in industries such as chemical, pharmaceutical, and food processing, such as butterfly valves and valve plates in chemical pipelines. After spraying, it can be adapted to transport corrosive fluids such as hydrochloric acid and caustic soda; The valves for reaction vessels that come into contact with various chemical reagents in the pharmaceutical industry can prevent corrosion and contamination of the reagents after the valve plate is sprayed; Valves in the field of food processing that come into contact with acidic and alkaline cleaning solutions or various types of food juices, this coating not only prevents corrosion but also meets hygiene requirements, ensuring food safety.
