PTFE Heat exchanger is a kind of important chemical heat exchange equipment, its development, development and practical application has undergone more than 20 years of evolution process, PTFE Tetrafluoroethane Heat Exchanger now has many different structures, different uses and performance of poly four vinyl chloride products. In the current industrial production use is more common is the row tube type and tube type heat exchanger.
PTFE heat exchanger and international chemical equipment new varieties, because of the corrosion resistance of poly Four vinyl chloride in a variety of alloys, non-metallic and even precious metals, such as gold, silver, zirconium and so on, such equipment to solve the pharmaceutical industry, PTFE Tetrafluoroethane Heat Exchanger petrochemical and other strong corrosive fluid materials heat transfer is of great significance. According to information reports, there are the United States, Britain, France, Germany, Italy, Japan and other countries, a number of factory enterprises widely used this new equipment, and China's manufacturing and application of this equipment has not been fully spread. 1965 a company developed successfully poly four vinyl chloride hydrochloric acid condensation absorber, PTFE Tetrafluoroethane Heat Exchanger replaced the traditional ceramic hydrochloric acid condensation absorber, glass condenser absorber and graphite equipment, PTFE Tetrafluoroethane Heat Exchanger greatly improving the heat exchanger corrosion resistance and heat transfer medium clean rate. In petrochemical, sulfuric acid, pharmaceutical electroplating, light industry and other fields have been widely used.
PTFE Heat Exchanger has a very broad development prospects, strengthen the research of F4 base materials to improve product application scope is the main direction of future development, and strive to develop new varieties, new series to adapt to the market. China's vast market, sulfuric acid, fertilizers, PTFE Tetrafluoroethane Heat Exchanger pharmaceuticals and other industries to upgrade equipment, and therefore need a large number of advanced, according to four vinyl chloride equipment.
Features of PTFE heat exchanger.
PTFE is a chemical lazy data, in addition to the high-temperature elements of fluorine, triclosan, such as a small amount of chemical substances, can be in all the media work, its spray after the PTFE heat exchanger has a very good anti-corrosion function, its functional characteristics are as follows:
1, because of the chemical laziness of PTFE tube, smooth appearance, winding and high expansion coefficient, so that its heat transfer surface is very difficult to scale, PTFE Tetrafluoroethane Heat Exchanger greatly reducing the number of equipment repair, to ensure a relatively stable heat transfer coefficient and production of long time operation.
2, PTFE heat exchanger Teflon does not contain photosensitive genes, so it has excellent resistance to atmospheric aging. In the strong corrosive medium its service life is 20 to 30 times times of stainless steel, PTFE Tetrafluoroethane Heat Exchanger plus eliminates the repair, the loss which the trouble stoppage forms, its induction cost certainly is lower than other heat exchanger.
3, PTFE heat exchanger heat transfer function is good, because the heat exchanger is selected thin-walled tube, so the PTFE data to overcome the low thermal conductivity of the defect, PTFE Tetrafluoroethane Heat Exchanger so that its total heat transfer coefficient can reach $number (w/㎡k). The heat transfer technique is used to improve the pressure resistance and the total heat transfer coefficient is improved.
4, PTFE heat exchanger small size, light weight, compact layout, PTFE Tetrafluoroethane Heat Exchanger unit volume of heat transfer area is exceptionally large, in transport, installation, repair is very convenient.
