Description
Technical field
The invention belongs to spinning device tool technical field, relate to a kind of spinnerets, especially relate to a kind of carbon fiber spinning tantalum spinnerets.
Background technology
The effect of spinnerets is with the high polymer molten of viscous state or solution, is transformed into the thread that the particular cross section shape is arranged by micropore, and process setting medium such as air or solidification liquid are solidified to form strand.Press the different of the classification of fiber and specification, present different specifications, shape and pass.Along with the development of science and technology, the synthetic fiber technology has also had significant progress, because it has the characteristics such as good fixed effect, high strength, good springiness, ABRASION RESISTANCE corrosion resistance are strong, synthetic fiber are used in the industrial production such as weaving, clothes in large quantities.In the production process of synthetic fiber, ejection forms as-spun fibre the spinneret orifice of melt from spinnerets, is processed into the finished product synthetic fiber through later process again.Existing circular hole spinnerets lacks enough variations, usually only has identical shaped spinneret orifice, the fiber of producing is solid construction, arranges closely the intermolecular hydrophilic-structure that lacks, the peripheral structure of fiber is also comparatively fixing, therefore smooth surface exists regain little, and hygroscopicity is poor, the technical problems such as warming effect is not good, simultaneously discharging pore structure is comparatively single.
The problem that exists in order to solve prior art, people have carried out long-term exploration, have proposed solution miscellaneous.For example, Chinese patent literature discloses a kind of profile spinneret [application number: 200920191737.0], charging face and to go out charge level all rounded, and charging face is provided with a plurality of charging holes, and charging hole is the concentric structure array from inside to outside, and the charging hole cross section is rounded; Go out charge level and be provided with a plurality of discharge openings, discharge opening is the concentric structure array from inside to outside, discharge opening by the center outwards radially the regularly arranged identical groove of five strips size consist of, the angle angle between two grooves of arbitrary neighborhood is identical.
Such scheme has improved prior art to a certain extent, and hole structure is novel, and spun silk gap is many, can make fabric have good gas permeability and warmth retention property.But, the defective such as because the structure of this scheme spinnerets is single circular configuration, thereby it still exists withstand voltage properties relatively poor, and is impaired easily during the spray silk, and service life is short, and the scope of application is extensive not.
Summary of the invention
The objective of the invention is for the problems referred to above, provide a kind of reasonable in design, simple in structure, can reduce wear, improve withstand voltage properties, corrosion resistance is strong, and is applied widely, the carbon fiber spinning tantalum spinnerets of long service life.
For achieving the above object, the present invention has adopted following technical proposal: this carbon fiber spinning tantalum spinnerets, comprise tabular body, be provided with some spinneret orifices at body, the one side of spinneret orifice is charging aperture, another side is discharging opening, and described body is made by tantalum material, described spinneret orifice in the form of a ring array distribution on body.
Make the body of spinnerets by tantalum material, so that the spinnerets quality is hard, have splendid ductility, the feature such as it is little to have simultaneously a thermal coefficient of expansion, and chemical property is outstanding, and corrosion resistance is strong.Spinneret orifice is the structure of array distribution on body in the form of a ring, and the circular jetting filament plate compared to traditional has the raising withstand voltage properties, prolongs the advantages such as life cycle, and it is required to be particularly useful for the spinning such as carbon fiber, aromatic series fiber, polyimide fiber, pbo fiber.
As preferably, in above-mentioned carbon fiber spinning tantalum spinnerets, described tantalum material thickness is greater than 0.5mm.
As preferably, in above-mentioned carbon fiber spinning tantalum spinnerets, described spinneret orifice is the concentric structure array from inside to outside on body.
In above-mentioned carbon fiber spinning tantalum spinnerets, described spinneret orifice is special-shaped spinneret orifice.The abnormity spinneret orifice be provided with the plying bunchy that is beneficial in the fibre spinning process, can select different spinneret orifice types according to different spinning needs simultaneously.
Further, in above-mentioned carbon fiber spinning tantalum spinnerets, described spinneret orifice is cross shaped spinneret orifice.The version of the spinneret orifice here can be taked according to actual spinning needs the alternative of multiple various kinds.
Further, in above-mentioned carbon fiber spinning tantalum spinnerets, described cross shaped spinneret orifice is comprised of four elongated cylindrical void concurrents, and the angle between the adjacent cylindrical void is the right angle.Similarly, the version of cross shaped spinneret orifice here also can be selected according to actual needs.
As preferably, in above-mentioned carbon fiber spinning tantalum spinnerets, described cylindrical void is wide structure.This structure is conducive to the even of spinning, and certain cylindrical void here also can adopt not wide structure.
As preferably, in above-mentioned carbon fiber spinning tantalum spinnerets, the width of described cylindrical void is between the 0.2-0.3mm.
Compared with prior art, the advantage of this carbon fiber spinning tantalum spinnerets is: reasonable in design, simple in structure, can reduce wear, improve withstand voltage properties, corrosion resistance is strong, and is applied widely, long service life, it is required to be particularly useful for the spinning such as carbon fiber, aromatic series fiber, polyimide fiber, pbo fiber.
