Teflon CapillaryThe molding process includes molding method, pushing method, extrusion method, hydraulic method, welding method, winding method, etc.
Push, extrusion is the most common, the most widely used.
Teflon CapillaryAfter mixing the dispersed resin and the booster, the fibers are subjected to shear forces in a die with a cone angle, so that the fibers are oriented and subjected to shear forces.
Drying, high temperature sintering, shaping and other processes made of special pipes.
1.Introduction of Teflon
PTFE (Polytetrafluoroethylene), abbreviatedPTFE, (commonly known“Plastic King, Hala”), trade nameTeflon®, in
Because of the pronunciation,“Teflon”This trademark is also called“Teflon”,“Teflon”,“Tiefulong”,“Teflon”,“Teflon”Wait
and so on, all“Teflon”The transliteration.
2. PTFECapillaryName
Teflon Capillary (PTFE), Teflon Capillary for TransformerHOSE tube, Teflon capillary tube, transformer bushing/capillary tube.

3. PTFECapillaryofCharacteristics
（1）High chemical stability: can withstand all strong acids, including aqua regia, hydrofluoric acid, concentrated hydrochloric acid, nitric acid, fuming sulfuric acid, organic acids
The role of strong bases, strong oxidants, reducing agents and various organic solvents. Ideal for high purity chemical feeding use.
（2）Low coefficient of friction: the coefficient of friction is generally only0.04, is a very excellent self-lubricating material, and the coefficient of friction does not vary with temperature.
Change and change;
（3）Excellent anti-adhesion, the inner wall of the tube is not easy to adhere to colloids and chemicals;
（4）Excellent aging resistance, can be used outdoors for a long time;
（5）Excellent electrical insulation properties:PTFE is a highly non-polar material with good dielectric properties, great resistance and a dielectric constant of 2.0
Left and right, which is the smallest of all electrical insulating materials;

According to the size of the pipe diameter can be dividedCapillaryandTwo types of HOSE tubes. HOSE tube inner diameter> 4mm, capillary inner diameter ≤ 4mm (generally speaking, inner diameter less than or equal to 4mm
called capillary).
5. PTFECapillaryofUse
Teflon capillary is suitable for petroleum, chemical, education, environmental protection, health, scientific research and other industries, PTFE capillary with its superior characteristics can be used as corrosion
For gas and liquid pipelines, in order to ensure the tightness and ease of use of PTFE capillary connection, two-way, three-way, ferrule and other instrument fittings can be used to connect
