The application of PTFE film is more and more extensive, and the application of similar functional materials has been developed recently.
PTFE film heat resistance and good self-wetting, can be widely used as high temperature liquid pipe and corrosive liquid pipe sealing material. For example, pipe joints in the heating industry have been
With hemp mixed with adhesive, now switch to PTFE film, can greatly increase the use cycle.
After a certain treatment of PTFE film with selective permeability, can be selectively through the gas or liquid, can be used as a separation material. For example, the graft copolymerization of TFE and N-vinyl pyrrole
The film produced by the material is a weak alkaline membrane, which can be used as a pervaporation membrane for separation and concentration, such as the concentration of ethanol and dimethylacetamide in concentrated water, and the separation distillation method is not.
Azeotrope capable of separation.
PTFE membranes produced by calendering are stretched at high temperatures and then heat treated to make porous membranes for gas-liquid separation, gas-gas separation and liquid-liquid separation, such as argon and its
Isotope separation, chloroform and water separation, etc.
In addition, such porous membranes can also be used to filter corrosive liquids. Because the film allows the diffusion of moisture and does not allow the diffusion of liquid water, it can also be made into ski clothing and golf balls.
It can keep the relative humidity of the skin at a certain level.
PTFE has the optical properties of low refractive index. PTFE can be coated on a specific substrate (quartz, transparent plastic) to produce an optical fiber material with a light guide loss of less than 10dB/km.
material. For example, PTFE coated quartz materials are being tested for plant cultivation and underground mall lighting. High transparent methyl and dimethacrylic polymers coated with fluorine resin can be used.
Made of optical fiber material, high light guide efficiency, has been successfully used in the production of medical endoscopes.
Some fluorine trees are ray-sensitive and belong to the radiation decomposition type materials, so they can be used as resists for integrated circuit production.
PTFE has the characteristics of preventing far infrared, and can be used for far infrared heaters to replace traditional single crystal materials such as NaO1 and AgC1.
PTFE is flame-resistant and heat-resistant. At present, many states in the United States have approved the use of PTFE film coated wires to replace indoor wires that were previously required to be installed in metal tubes.
50% down.
PTFE film has the advantages of flame retardant, aging resistance and anti-pollution, and can be used as a roof material. Japan's Daikin Industries successfully uses PTFE membrane for large inflatable support buildings
Roof materials, such as stadiums, tennis courts and sales centers. This kind of house can be kept clean for a long time; in snowy days, the snow can automatically slide down to prevent the roof from accumulating snow.
PTFE film has no side effects on the human body and is non-toxic, and can be widely used as human organs, such as artificial blood vessels, heart valves, etc.
