The General Administration of Quality Supervision, Inspection and Quarantine announced yesterday that as of September 15, it received 6,692 complaints related to automobile products, and 70 enterprises carried out 119 recalls involving 201,600 vehicles with defective vehicles, including the recall of enterprises under the influence of the defects of the AQSIQ. There were 1,115,200 vehicles, accounting for 55% of all recalls. In addition, the implementation of children's toys recalled 25 times, involving 24,600 children's toys. The implementation of household appliances recalled 5 times, involving 1,182,300 household appliances. PTEF Immersion Heaters, PTFE Immersion Heater Element, Fluoropolymer Heaters, PTFE Guangzhou Quanxu Technology Co Ltd , https://www.silicamattingagent.comTeflon is Polytetrafluoroetylene, referred to as Teflon, PTFE, F4, etc.It is also known as Teflon, Teflon, Teflon, Teflon and so on because of its pronunciation.Polytetrafluoroethylene (ptfe) is a kind of plastic, which is used to manufacture heaters. It has been successfully used in chemical equipment heating. It has the characteristics of multi-layer and three-dimensional heating.
The working pressure, working temperature, heat transfer coefficient and installation method of the teflon heater vary greatly according to different types, different shell materials and different thermal media.The chemical properties of teflon are very stable and the corrosion resistance is especially good.The surface of the teflon tube is smooth and moderately flexible, so it is not easy to scale due to the slight vibration when using it.The teflon heater is small in size and compact in structure. The heat transfer area per unit volume of the equipment is more than 4 times of that of the shell heater.Flexible teflon tubes work safely under shock and vibration of fluids, and the tubes can be made into special shapes as needed.Teflon has low thermal conductivity, poor mechanical properties than metal, and is not resistant to high temperature.The use of small diameter, thin wall, although the thermal conductivity and mechanical properties of compensation, but can only be used in the case of low pressure and low temperature.The production of teflon steam heater and teflon hot water heater has become more and more mature, and widely used in chemical industry, medicine, pickling and other corrosive industries.
