Teflon
Teflon, Teflon, etc. It is a polymer compound
made of tetrafluoroethylene
. Its simplified structural formula is: It has excellent chemical stability and corrosion resistance. It is the most corrosion-resistant
br/>One of the best performing materials, except molten alkali metals, chlorine trifluoride, chlorine pentafluoride and liquid fluorine
It is resistant to all other chemicals and does not change when boiled in aqua regia
, widely used in various occasions that require resistance to acids, alkalis and organic solvents. Sealing, high lubrication, non-stick, electrical insulation and good anti-aging ability, excellent temperature resistance (can work for a long time at temperatures from ℃ to ℃). PTFE itself is not toxic to humans.
The operating temperature is ~℃, allowing rapid cooling and heating, or alternating hot and cold operations.
The pressure is fully negative to /) ( )
Today, various types of plastic products have been used in chemical machinery
electronics
electrical appliances
military industry
aerospace
/>Environmental protection
and bridges
have played a decisive role in the national economy.
Advantages
High temperature resistance and working temperature up to ℃.
Low temperature resistance and good mechanical toughness, it can maintain a high elongation even if the temperature drops to ℃.
Corrosion resistance to most chemicals and solvents, showing inertness and resistance to strong acid and alkali water and various organic solvents.
Weather resistant and has the best aging life among plastics.
High lubrication is the lowest friction coefficient among solid materials.
Non-adhesion is the smallest surface tension in a solid material and does not adhere to anything.
It is non-toxic and physiologically inert. As artificial blood vessels and organs, it can be implanted in the body for a long time without adverse reactions.
Electrical insulation can resist high-voltage electricity.
The relative molecular weight of polytetrafluoroethylene is relatively large, ranging from hundreds of thousands to more than 10 million.
Usage
It is used in the production of materials such as rods, tubes, sheets, cable materials, raw materials and tapes. After secondary processing, it can also be made into thin sheets, films and various special-shaped products. It can also be used as a lubricant thickener.
As an additive for plastics, rubber coatings, inks, lubricants, greases, etc.
Thin-wall tubes and thin bars are made by push molding, special-shaped bars, and the insulation layer of wires and cables is rolled into thin strips to be used as pipe thread sealing materials.
In the mechanical, electronic, chemical and other industries, it is used for spraying, impregnation, etc.
Used for making impregnated coatings.
It is made into rods, sheets, tubes, films and various special-shaped products, which are used in aerospace, chemical, electronic machinery, medicine and other fields.
Made into high-insulation electrical parts, high-frequency resistant wire and cable sheaths, corrosion-resistant chemical vessels, high-cold-resistant oil pipelines, artificial organs, etc.
Used in battery fiber cloth, etc.
Manufacture of film tubes, plates, rods, bearings, gaskets, valves, chemical pipeline fittings, equipment container linings, etc., used in electrical, chemical, aviation, machinery and other fields.
It is used in the electrical industry and is used as an insulating layer of corrosion-resistant and wear-resistant materials for power supply and signal lines in aerospace, aviation, electronics, instrumentation, computers and other industries.
Quartz glassware is used in ultra-pure chemical analysis and storage of various acid-base organic solvents in atomic energy, medical semiconductor and other industries.
