1. Teflon (PTFE1) Introduction
PTFE (Polytetrafluoroethylene), abbreviatedPTFE, (commonly known“Plastic King, Hala”), trade nameTeflon®In China, because of the pronunciation,“Teflon”This trademark is also called“Teflon”,“Teflon”,“Tiefulong”,“Teflon”,“Teflon”And so on, all“Teflon”The transliteration.
Brief Introduction of 2. Teflon Capillary
1,Introduction of Teflon Capillary
Teflon capillary tube is made of polytetrafluoroethylene (pteeCommonly known as Teflon, plastic king) material extrusion sintering, drying, high temperature sintering, shaping and other processes made of special pipes. Because the tube is the same size as the blood vessel, it is also knownTeflon Capillary.
2, what is teflon capillary?
Teflon capillary tube is made of polytetrafluoroethylene dispersion resin at room temperature with organic solvent as an extrusion aid.,It is then dried and sintered. According to the size of the pipe diameter can be divided into capillary andHOSETubeTwo kinds.hoseTube inner diameter>4mm,Capillary inner diameter≤ 4mm. With high temperature resistance (260℃), corrosion resistance, high insulation, with excellent electrical characteristics. The colors are transparent, black, blue, red, yellow, green, the product has excellent dielectric properties andChemical resistance, High temperature resistance, high pressure resistance, non-absorbent, non-sticky, non-conductive, low friction coefficient and non-aging properties. Widely used in transformers, electronic appliances, communication equipment, chemical fluids, machinery manufacturing, medical equipment and automotive aerospace and other fields.

3,Teflon capillary specific performance
Teflon capillary has a high degree of chemical stability: it can withstand all strong acids, including aqua regia, hydrofluoric acid, concentrated hydrochloric acid, nitric acid, fuming sulfuric acid, organic acids, strong alkali, strong oxidant, reducing agent and various organic solvents. Ideal for high purity chemical feeding use.
4, What are the characteristics of Teflon capillary?
Teflon capillaries have a low coefficient of friction, which is generally only0.04, Is a very excellent self-lubricating material, and the friction coefficient does not change with temperature. Excellent anti-adhesion, the inner wall of the tube is not easy to adhere to colloids and chemicals.※excellentAging resistanceIt can be used outdoors for a long time. Teflon capillary excellent electrical insulation properties:ptfeIt is a highly non-polar material with good dielectric properties, great resistance, and a dielectric constant2.0It is small in all electrically insulating materials. Teflon capillary tube part of high transparency, easy to observe the internal fluid condition.

3Teflon Capillary FAQ
1,Teflon capillary heat exchanger
Teflon material temperature characteristics and corrosion resistance in the application of heat exchanger, so that the Teflon heat exchanger in the corrosion industry has been widely used, such as chemical industry, pickling, electroplating, medicine, anodic oxidation and other industries. Teflon heat exchanger mainly has excellent corrosion resistance, good anti-scaling, good anti-aging performance, good heat transfer performance, low resistance, small size, light weight and compact structure.
2,Teflon Capillary Connector
Teflon Capillary Connector,Disclosed is a capillary connector that is easy to disassemble.,It includes studs,Seal press ring and threaded joint,Threaded connection of the stud and threaded joint,TheSeal pressure ringThe two ends are respectively in contact with the stud and the threaded joint,The capillary in turn passes through the threaded joint,Seal ring and stud,The surfaces of the sealing pressure ring and the stud in contact with each other are respectively conical surfaces with matching structures.,This kind of joint after the sealing pressure ring is seriously deformed and the threaded joint is stuck,Due to its combinatorial design structure,Makes it fairly easy to disassemble.The sealing joint only needs to seal the contact surface of the stud and the sealing pressure ring and the contact surface of the sealing pressure ring and the capillary tube,Less jacking force required to complete the seal,Small extrusion deformation caused by sealing pressure ring during use,Sealing pressure ring is less damaged,It is beneficial to reuse many times and has a certain effect of preventing the pressure ring from sticking to other components.
4.Teflon capillary applications
Teflon capillaries are widely used in machinery, electronic appliances, automobiles, aerospace, chemicals, computers, electric heating, military, petroleum, education, environmental protection, health, scientific research and communications and other important scientific and technological industries, such as micro-transformers.Teflon CapillaryWith its superior characteristics can be used as corrosive gas, liquid pipeline, in order to ensuretetrafluoro capillaryFor the tightness of the connection and the convenience of use, two-way, three-way, clamping sleeve and other instrument pipe fittings can be used.
