  1. Teflon spiral protective casing

  There are several types of Teflon spiral protective sleeves. Teflon straight pipes can be used, or Teflon rotary cut pipes can be used. They are wound pipes on the market, depending on the application requirements.

  Teflon spiral protective sleeve is a special pipe made of polytetrafluoroethylene (PTFE commonly known as Teflon, plastic king) material after extrusion and sintering, drying, high temperature sintering, and shaping. Teflon is also called Teflon, Teflon, Teflon, Teflon, Teflon, PTFE, Plastic King, and Teflon in English. It is widely used in machinery, electronic appliances, automobiles, aerospace, and chemicals. , Computers, electric heating, military, communications and other important technology industries, such as miniature transformers.

  Features of Teflon spiral protection casing:

  1. High chemical stability: can withstand all strong acids, including aqua regia, hydrofluoric acid, concentrated hydrochloric acid, nitric acid, fuming sulfuric acid, organic acids, etc., strong alkalis, strong oxidants, reducing agents and various organic solvents . It is very suitable for feeding high-purity chemicals.

  2. Low coefficient of friction: The coefficient of friction is generally only 0.04, which is a very excellent self-lubricating material, and the coefficient of friction does not change with changes in temperature.

  3. Excellent anti-sticking property, and 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 performance: PTFE is a highly non-polar material with good dielectric properties, great resistance, and a dielectric constant of about 2.0, which is the smallest among all electrical insulation materials.

  6. Part of the tube has high transparency, and the internal fluid condition can be easily observed.

  Two, Teflon tube

  Teflon is a registered trademark used by DuPont on its series of fluoropolymer products. It was invented and manufactured in the Jackson laboratory by Dr. Roy J. Plunkett.

  The scientific name of Teflon tube is polytetrafluoroethylene, the full English name is Polytetrafluoroetylene, PTFE, F4, etc. for short. It is a synthetic polymer material that uses fluorine to replace all hydrogen atoms in polyethylene. This material is resistant to acids, alkalis, and various organic solvents, and is almost insoluble in all solvents. At the same time, PTFE has the characteristics of high temperature resistance, and its friction coefficient is very low, so it can be used for lubrication, and it has become an ideal coating for easy cleaning and maintenance and the inner layer of water pipes.

  Teflon tube characteristics:

  1. Non-sticky: Almost all substances are not bonded to the PTFE film. Very thin films also show good non-stick properties.

  2. Heat resistance: PTFE coating film has excellent heat resistance and low temperature resistance. It can withstand high temperature to 300°C in a short time, and generally can be used continuously between 240°C and 260°C. It has remarkable thermal stability. It can work at freezing temperature without embrittlement and does not melt at high temperature.

  3. Sliding property: PTFE coating film has a low friction coefficient. The friction coefficient changes when the load is sliding, but the value is only between 0.05-0.15.

  4. Moisture resistance: The surface of the PTFE coating film does not stick to water and oil, and it is not easy to stick to the solution during production operations. If there is a small amount of dirt, it can be removed by simply wiping. Short downtime, saving working hours and improving work efficiency.

  5. Wear resistance: Under high load, it has excellent wear resistance. Under a certain load, it has the dual advantages of wear resistance and non-sticking.

  6. Corrosion resistance: PTFE is hardly corroded by chemicals, and can withstand all strong acids (including aqua regia), strong oxidants, and reduction except molten alkali metals, fluorinated media, and sodium hydroxide above 300°C The role of chemicals and various organic solvents can protect parts from any kind of chemical corrosion.

  3. Ptfe thin-walled tube production plant

  The conventional wall thickness of Teflon tube is 1 wall thickness, thicker ones have 2 wall thicknesses, 3 wall thicknesses, and thicker ones can reach 10 wall thicknesses. Thin-walled tubes refer to those with a wall thickness of 0.8/0.6/0.5/0.3 and so on. Most of the thin-walled tubes are used in the medical industry.

  Ptfe thin-walled tube characteristics:

  High temperature resistance: long-term use temperature 200~260 degrees;

  Low temperature resistance: still soft at -100 degrees;

  Corrosion resistance: resistant to aqua regia and all organic solvents;

  Weather resistance: the best aging life among plastics;

  High lubrication: has the smallest coefficient of friction in plastics (0.04);

  Non-sticky: It has the smallest surface tension among solid materials and does not adhere to any substances;

  Non-toxic: with physiological inertness; excellent electrical properties, is an ideal C-level insulating material.

  Ptfe thin-walled tube is made of suspension polymerized polytetrafluoroethylene resin through plunger extrusion processing. Among the known plastics, PTFE has the best chemical resistance and dielectric properties. Polytetrafluoroethylene braided packing is a good dynamic sealing material. It is woven from expanded polytetrachloroethylene tape. It has low friction coefficient, wear resistance, chemical corrosion resistance, good sealing, no hydrolysis, no Excellent performance such as hardening. Used for gasket seals and lubricating materials working in various media, as well as electrical insulation, capacitor media, wire insulation, electrical instrument insulation, etc. used under various frequencies.
