High-strength high-modulus polyethylene fiber or elongation chain (ECPE) polyethylene fibre, it is in (1-6) × 10 by relative molecular mass6It is poly-
Ethene obtains after spinning, super drawing.Superhigh molecular weight polyethylene fibers composite material has compared with other fibre reinforced composites
There are lighter quality, more preferable dielectricity and impact resistance, therefore be widely used in aerospace, marine site defence, weapon dress
The field such as standby.
At present, the main technological steps of common gel spinning manufacture superhigh molecular weight polyethylene fibers have：By superelevation
The polyethylene of molecular weight is dissolved in solvent and is made into polyethylene solution, which extrudes through screw extruder, after spinning, cooled and solidified
Gelation collagen silk, then extracts solvent therein with volatile extractant, dry, and super multiple stretching, finally obtains superelevation
Molecular weight polyethylene fiber.According to the difference for selecting solvent, gel spinning is divided into two kinds of dry and wet.Dry spinning is adopted
Make solvent with decahydronaphthalene, decahydronaphthalene is volatile, eliminates follow-up extraction workshop section, but decahydronaphthalene is expensive, greatly improves
The cost of production, in addition to Dutch DSM, Japanese Japan spin company and uses dry process, other companies use wet processing.
Wet spinning uses high boiling solvent (such as paraffin oil, mineral oil), and the precursor prepared through gel spinning is a kind of highly molten
Swollen gelinite, including a large amount of high boiling solvents makes macromolecular chain solvation, reduces the secondary bond power of interchain and the point that tangles is close
Degree.Solvation reduces the relaxation activation energy of macromolecular chain, activity increase, in bearing tension force, especially at high temperature
Relative sliding during stretching, reduces the intensity and modulus of fiber, it is therefore necessary to remove solvent.
High boiling solvent in gel strand is generally removed using extraction mode at present, the extractant used be mainly gasoline,
Benzene,toluene,xylene, fluorochlorohydrocarbon, petroleum ether, halogenated hydrocarbons etc., the inflammable and explosive characteristic of such solvent generally existing, production process
In be prone to accidents, the production safety of serious threat to enterprise.And currently in order to the effect of extracting of raising precursor, generally uses
Supersonic generator is set in extraction equipment, and the power of ultrasonic wave reaches 30 kilowatts per hour, and which not only improves equipment
Input cost, also there is the possibility that apparatus failure occurs, and high-frequency ultrasonic vibration can produce thermal energy, improve extraction equipment
Interior temperature, this can all increase the danger that burning or explosion occur for extractant.
