Abstract
The utility model relates to band Vltrasonic device finish groove, and mainly solve in prior art and adopt common finish device, oil uneven, the carbon fibre precursor intensity of spinning gained is low, the problem of unstable properties.The present invention is by adopting a kind of finish groove, comprise the finish groove cell body (3) that band is ultrasonic, it is characterized in that, also comprise ultrasonic generator, described ultrasonic generator is positioned at the technical scheme of finish groove cell body, solve this problem preferably, in the industrial production of the carbon fibre precursor that can be used for.
Description
Technical field
The utility model relates to spinning process finish groove, and more particularly, the utility model relates to for carbon fibre precursor spinning process finish groove.
Background technology
Precursor is the prerequisite producing high-performance carbon fibre, and in spinning process, the uniformity oiled often determines the wire broken rate of fiber and the stability of line density, impact finally obtains the performance of precursor, thus affect pre-oxidation carbonization process, finally directly affects the performance of carbon fiber, in spinning process, use suitable oiling device to be obtain the basis of stablizing high-quality carbon fiber precursor thus.And suitable oiling device can increase convection current, increase mass transfer flowing, finish is fully infiltrated in fiber, can the effect that oils be improved, make to oil evenly, be conducive to follow-up pre-oxidation carbonisation.
Chinese patent CN203294593U discloses a kind of circulating oil type finish groove, comprise finish groove body, finish dispensing pump and finish mouth, one end of described finish dispensing pump connects finish groove body, the other end connects finish mouth, it is characterized in that, this finish groove body is configured with one can impel the circulating pump that in finish groove body, finish mixes, and the import of circulating pump is all communicated with finish groove body with outlet.But for how for more effectively making to oil evenly, be not described later in detail, because the technological requirement prepared than general fiber due to the preparation of carbon fibre precursor is higher, convergence requires also high, uneven if oiled, will make the phenomenons such as fibre spinning process generation lousiness, prepared fibre property is unstable, the final performance affecting carbon fiber, so must prepare a kind of effective oiling method to solve this problem.
Utility model content
The utility model relates to band Vltrasonic device finish groove, mainly solves in prior art and adopts the carbon fibre precursor intensity of common finish device spinning gained low, the problem of unstable properties.The present invention oils by being with the finish groove of Vltrasonic device, and the finish groove of this Vltrasonic device solves this problem preferably, in the industrial production of the carbon fibre precursor that can be used for.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows: a kind of finish groove, comprises finish groove cell body (3), it is characterized in that, also comprise ultrasonic generator, and described ultrasonic generator is positioned at finish groove cell body.
In technique scheme, this Vltrasonic device described is preferably ultrasonic generator; The quantity of described ultrasonic generator is preferably 2-10, is more preferably 3-5; Interval between described ultrasonic generator is preferably 5-20mm, is more preferably 8-15mm; Described ultrasonic generator is positioned at bottom finish groove cell body, sidewall or end wall, is more preferably positioned at finish trench bottom, is more preferably positioned at bottom finish groove cell body, below finish groove live-roller; The live-roller diameter of described finish groove is preferably 80-500mm, is more preferably 100-400mm; The live-roller of described finish groove is preferably one or more; The live-roller material of described finish groove cell body, finish groove is all preferably steel; In described finish groove, the temperature of finish is preferably 10-50 DEG C, more preferably 15-30 DEG C.
The band ultrasonic finish groove of the utility model owing to selecting special construction, makes the fiber uniformity that oils be improved, can increase convection current, increase mass transfer flowing, finish is fully infiltrated in fiber, can the effect that oils be improved, make to oil evenly, be conducive to follow-up pre-oxidation carbonisation.This design can control the uniformity that fiber oils effectively, thus ensures the stability of fibre number, can obtain the carbon fibre precursor of high compactness, high strength.
Adopt the technical solution of the utility model, gained precursor oils evenly, and oil applying rate can reach 1.37%, and fiber number is 1.21dtex, and filament strength is 6.5cN/dtex, and precursor density is 1.183, achieves good technique effect.
