The Tetrafluoroethane Heat Exchanger Has A Long Service Life
PTFE heat exchanger tube bundle using PTFE thin-walled capillary, to make up for the shortcomings of plastic thermal conductivity low, PTFE Tetrafluoroethane Heat Exchanger to overcome the liquid laminar flow phenomenon, that is, to play a strong corrosion resistance of PTFE, but also improve the heat transfer Efficiency and the same size of the heat transfer area. Heat exchanger using advanced welding technology, to overcome the previous PTFE heat exchanger welding leakage problem, the welding strength of up to 1.5MPa.
PTFE heat exchanger is divided into tube-type and shell-and-tube; tube bundle is the heat exchanger is installed directly in the heat exchanger solution to the container, to achieve the exchange of heat. Tube-type heat exchanger installation, easy maintenance, easy to use; tube-type heat exchanger plate (placed on the side of the groove) W-shaped, U-shaped, L-shaped (placed in the bottom), one or the shape, PTFE Tetrafluoroethane Heat Exchanger Shaped and other special shape, can also be formed according to customer requirements
The choice of tetrafluoroethane heat exchanger
There are two main categories of tetrafluoroethane heat exchangers for the pre-treated production line: Tubular, Tubular. Its structure and selection of the details of our factory to provide the product description, PTFE Tetrafluoroethane Heat Exchanger where the main talk about how to use different heating methods using tetrafluoroethane heat exchanger.
1, tube-type heat exchanger is a direct heating method, it has a simple structure, the price is cheaper than the shell and tube heat exchanger, heat transfer efficiency than the shell heat exchanger, easy installation and maintenance features. However, the tube-type heat exchanger is an open-type structure, PTFE Tetrafluoroethane Heat Exchanger such as improper operation, easy to be injured by the workpiece, it must do protection frame to protect the tube bundle, and the frame fixed to the groove.
2, shell and tube heat exchanger with slot outside the heating method, is a closed structure, due to the cycle of heating, must use the circulating pump, an increase of power consumption, and heating process has a certain heat loss, so the heat exchanger efficiency Slightly lower than the tube bundle, but it is heated evenly, the cycle of the process to promote the mixing of the bath to accelerate the chemical reaction, PTFE Tetrafluoroethane Heat Exchanger because it belongs to the closed structure, not contact with the workpiece, but maintenance than the tube heat exchanger trouble.
In the pickling station, we recommend the use of tube-type heat exchanger, which is the most economical and efficient heating, and its long service life.
Phosphorus chemical plant, depending on the specific circumstances, can be used tube heat exchanger or shell and tube heat exchanger heating solution, the use of tube-type heat exchanger is simple and economical, but to regularly carry out the tube and the deposition of phosphorus deposition on the framework, Teflon tube bundle smooth and thermal expansion, clearance is also relatively easy, the general cycle of 1 week to half a month.
Small coating equipment pretreatment pickling and phosphating, but also the choice of polytetrafluoroethylene electric heater, generally in the tank less than 2m3 can choose this way heating, the input cost is low, PTFE Tetrafluoroethane Heat Exchanger no heat, heating time quickly.
Development Trend of Tetrafluoroethane Heat Exchanger
As the tetrafluoroethane heat exchanger with corrosion resistance, anti-scaling, energy efficient performance, in the domestic and international surface treatment of professional heating or cooling and other fields, has been rapidly promoted and used, but the tetrafluoroethane heat exchanger raw materials Expensive, to a certain extent, limited its popularity of large areas. In recent years, for this issue, we organize the strength of the research and trial success of polytetrafluoroethylene-soluble polytetrafluoroethylene (PFA), poly perfluoroethylene (FEP) heat exchangers, polyethylene (PE) This kind of polymer polymer temperature to adapt to the narrow regional shortcomings, we have a major breakthrough in the structure of the heat exchanger, from the thermodynamic theory, PTFE Tetrafluoroethane Heat Exchanger the use of tube fluid volume diffusion method, so that the fluid into the capillary pressure, the temperature quickly Down to ensure the heat resistance of such heat exchangers. At the same time, in these polymer polymer by adding anti-aging agent to ensure that the life of these heat exchangers up to 3-6 years, and we were pleasantly surprised to find that according to Ou good good low temperature performance of ultra-high molecular weight polyethylene Heat exchanger, not only long-term adaptation to -35 ℃ below the low temperature environment, but also in the 1.5Mpa pressure without leakage, the air tightness is much better than other materials, thus solving the tetrafluoroethane heat exchanger due to high pressure air tightness Leading to leakage, and can not produce a direct cooling system heat exchanger problems for low-temperature refrigeration (hard anodizing) process provides a highly efficient energy-saving, affordable heat transfer equipment.
The application of the new polymer polymer heat exchanger is successful because we have better grasp and develop the structural characteristics of the capillary type of the tetrafluoroethane heat exchanger. Under the condition of different working conditions, the most suitable tetrafluoroethylene Heaters, PTFE Tetrafluoroethane Heat Exchanger conform to the development of the market economy law, in the surface treatment industry plating and coating equipment to make more value online.
