PTFE heater exchanger
PTFE heater exchanger is widely used for heat conversion in acid-base environments in the chemical industry that be heated and chilled the liquid
The heat exchanger made of PTFE, also known as polytetrafluoroethylene, commonly known as "Plastic King", is a polymer compound formed by the polymerization of tetrafluoroethylene. It has excellent chemical stability, corrosion resistance, sealing, High lubricating, non-sticky, electrical insulation and good anti-aging endurance. The heat exchanger made of this material has the same performance as the raw material, and has the advantages of corrosion resistance, strong aging resistance, high temperature resistance, low temperature resistance, and non-toxicity.
1.heater
The heater heats the fluid to the necessary temperature, but there is no phase change in the heated fluid.
2. Preheater
The preheater preheats the fluid and provides standard process parameters for process operations.
3. Superheater
The superheater is used to heat the fluid (process gas or steam) to a superheated state.
4. Evaporator
The evaporator is used to heat the fluid to a temperature above the boiling point, so that the fluid evaporates, generally with a phase change.
PTFE, PTFE (polytetrafluoroethylene) non-stick coatings can be used continuously at 260°C, with a maximum operating temperature of 290-300°C, extremely low friction coefficient, good wear resistance and excellent chemical stability . Teflon FEP: FEP (fluorinated ethylene propylene copolymer) non-stick coating melts and flows to form a non-porous film during baking. It has excellent chemical stability and excellent non-stick characteristics. The maximum use temperature is 200 ℃.
PTFE (polytetrafluoroethylene) non-stick coating can be used continuously at 260, with a maximum operating temperature of 290-320, extremely low friction coefficient, good wear resistance and excellent chemical stability. It cannot be injection molded, but can be extruded or used as paint. High mechanical strength, good toughness, high tensile and compressive strength. The specific tensile strength is higher than that of metal, and the specific compressive strength is comparable to that of metal, but its rigidity is not as good as that of metal. The tensile strength is close to the yield strength, more than twice as high as ABS. The ability to absorb shock, stress and vibration is strong, and the impact strength is much higher than that of general plastics, and is better than acetal resin.
