Teflon 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.

For the current road engineering, it is very important to make the street lamp configuration when purchasing solar led street lamps. In order to ensure the quality of street lamps, how to optimize the design of the system when performing solar led street lamp configuration? The solar led street light system is composed of photovoltaic components. Therefore, in order to ensure the optimal design of the system, it is necessary to ensure the reasonable configuration of each component: 1. The battery plays a very important role in the whole street lamp system, in addition to considering the battery in the system configuration. In addition to the capacity configuration, the service life of the battery should also be taken into consideration. In order to ensure the life of the battery, the sealing process of the battery, especially the wiring, must be done during the installation process to prevent the short circuit of the battery from being affected by the humidity. 2. The configuration of the light source is very important to ensure the quality of the entire road illumination. The main consideration is the light decay of the light source when the light source is selected. The theoretical illumination duration of the LED light source takes 100,000 hours to take into account the light decay. The actual light source illumination duration is 5- About 80,000 hours. 3. When the street lamp system is configured, the loss of the line should also be taken into consideration. In the current configuration of the solar led street lamp system, the power is actually the total power including the power of the light source and the line loss. If the street lamp system is configured only Considering the power of the light source will affect the stability of the entire system and the service life of the group price. When the street lamp is configured, the solar street lamp manufacturer can only optimize the design of the street lamp system to ensure long-term stable lighting in the solar led street lamp road project.
