Description
Technical field
The present invention relates to polytetrafluoroethylfilament filament strand technical field, more particularly to a kind of polytetrafluoroethylfilament filament strand are equal
Even hot gas spring device.
Background technology
High-performance fiber prepares Nomex or spun lacing felt by acupuncture or liquid drugs injection technique, Nomex or spun lacing felt it is clipped,
Suture obtains the high temperature filtration bag of filtering high-temperature flue gas.Polytetrafluoroethylene (PTFE) has excellent heat endurance, can be in 260 DEG C of environment
In work long hours；Good chemical stability, it is any insoluble in other except being slightly soluble in itself fluoride and molten alkali metal
Solvent；Prominent surface non-stick, it is known that solid material all cannot be bonding with it.Therefore, polytetrafluoroethylfilament filament strand is
Ideal material as filtering high-temperature flue gas bag suture.During filtering high-temperature flue gas, high-temperature flue gas is to the continuous of filter bag
Impact is easily so that the breakage of polytetrafluoroethylfilament filament strand, fracture, cause high temperature filtration bag to fail.Therefore, polytetrafluoroethylene (PTFE) is improved
The intensity and uniformity of filament yarns have great importance the service life for extending high temperature filtration bag.Wherein, to polytetrafluoro
Ethene filament yarns carry out the main method that drawing and heat-setting is the intensity and uniformity that improve polytetrafluoroethylfilament filament strand.For
This, people carry out numerous studies to filament yarns drawing and heat-setting device, and specific method is as follows：
(1) CN200310111699.0 discloses a kind of device for improving fiber yarn forming performance, the thermal finalization dress in patent
Put be it is a kind of be made of inner and outer tubes, the closure member of connection closed at both ends.Interlayer is formed between inner and outer tubes, fibre bundle is worn
Heat setting device inner tube is crossed, high temperature steam state medium makes macromolecular chain elongation, sliding in fibre bundle, so as to improve the intensity of fibre bundle
And uniformity.But the heat setting device is only applicable to the production of the short fine resultant yarn system of chemical fibre, is not suitable for polytetrafluoroethylfilament filament
The production of strand thermal finalization.

Lower housing shell surrounds inner chamber body, and inner chamber body includes the upper cavity being located in upper shell and the lower chamber in lower housing shell.Pacify respectively
Heating unit on upper shell and lower housing shell provides heat and passes through inner chamber body, inner cavity to inner chamber body, filament fiber or yarn
The heat of body makes the macromolecular chain in filament fiber or yarn stretch, slide, so as to improve the strong of filament fiber or yarn
Degree and uniformity.But for the heat setting process of one filament or strand, the heat setting device high energy consumption and long filament or strand
Local heating is uneven, influences the intensity and the uniformity of long filament or strand.
(3) CN201320215305.5 discloses a kind of PBO filament fibers heat setting device, and the heat setting device is using high
The flowing of warm circulating nitrogen gas to provide heat to thermal finalization furnace chamber, and PBO filament fibers absorb heat from thermal finalization furnace chamber again makes PBO
Macromolecular chain stretches and forms the preferable PBO filament fibers of comprehensive performance in filament fiber.But the device is passed using nitrogen circulation
Defeated heat system, causes the waste of energy.If the heat setting device is used for polytetrafluoroethylfilament filament strand drawing and heat-setting, nitrogen
Gas dissolves in polytetrafluoroethylene (PTFE) at high temperature, influences the ordered arrangement of polytetrafluoroethylene (PTFE) macromolecular chain, reduces polytetrafluoroethylene (PTFE) length
The intensity and the uniformity of thread line.
In conclusion improve the stove of the device of fiber yarn forming performance, high temperature cavity heat setting device and high temperature circulation nitrogen
Chamber heat setting device is not all suitable for polytetrafluoroethylfilament filament strand drawing and heat-setting.In order to overcome above-mentioned heat setting device can not
