Performance fibers material, has been widely used for Aero-Space, national defense construction, Leisure Sport articles for use, medical apparatus and instruments and building trade.
Carbon fiber can be divided into polyacrylonitrile-radical, asphaltic base, viscose-based carbon fiber, and wherein polyacrylonitrile-based carbon fibre purposes is the widest, consumption
Maximum, with the fastest developing speed, have overwhelming superiority in carbon fiber produces.
Polyacrylonitrile-based carbon fibre is prepared through pre-oxidation, carbonization process by polyacrylonitrile fibre.Polyacrylonitrile fibre
Cost accounts for the 50~60% of carbon fiber totle drilling cost.Low cost, the polyacrylonitrile fibre of high-quality are commercial production high-performance polypropylenes
The basis of itrile group carbon fiber.At present, domestic more main flow is that polyacrylonitrile fibre is prepared in spinning in a wet process, full-bodied poly-third
The dimethyl sulphoxide solution (polymer fluid) of alkene nitrile successively through multistage coagulating bath molding, washing, hot water drawing-off, oil, be dried densification
Change, steam drafting, relaxation heat setting technique prepare polyacrylonitrile fibre.
During polymer fluid coagulation forming, solvent dimethyl sulfoxide separates send out simultaneously with coagulator water double diffusion and solidifying phase
Raw, tow solidification is from outward appearance to inner essence gradually completing, fiber surface and the asynchronism of solidified inside, causes fibrous inside to produce a large amount of
Hole.Tow washing step mainly completes fiber surface and pore interior carries the washing work of dimethyl sulfoxide, to ensure silk
The internal dimethyl sulfoxide content of bundle is reduced to less than 0.09%.Under the conditions of certain washing process, the dimethyl that tow carries is sub-
Sulfone is the most, and water rinses water loss is the biggest, and wastewater discharge also can increase accordingly, and dimethyl sulfoxide waste increases, and poly-third
Alkene nitrile fiber production cost rises.
Big tow (12K, 24K, 48K etc., term " 12K " represents that every bundle fiber contains 12000 ultimate fibres) polyacrylonitrile
During wet spinning, go out coagulating bath tow because carrying the dimethyl sulphoxide solution of a large amount of high concentration containing a large amount of holes, go out
After coagulating bath tow enters follow-up washing process, because carrying a large amount of sulfoxide solution, washing load is relatively big, and water consumption is relatively big, simultaneously
The water lotion overwhelming majority is discharged with sewage form, and therefore dimethyl sulfoxide loss is more, and spinning cost is bigger.
Summary of the invention
The purpose of this utility model patent is to provide a kind of big tow polyacrylonitrile wet spinning press-roller device, and this device can
Polyacrylonitrile wet spinning is gone out the substantial amounts of high-concentration dimethyl sulfoxide aqueous solution carried in coagulating bath tow surface and hole
Extrusion, centralized recovery, reduces the cleaning load of follow-up washing process, reduces sulfoxide loss, reduce wet spinning cost.
This utility model be the technical scheme is that
A kind of big tow polyacrylonitrile wet spinning press-roller device, it includes that live-roller, press roll adjusting device and sulfoxide are molten
