Wherein, UNMWPE extrusion molding main frame assembly 1 comprises the first extruder 15, and this first extruder 15 can adopt double screw extruder or plunger piston extrusion machine.Those skilled in the art know, and also can adopt the extruder that can realize superhigh molecular weight polyethylene material melt molding of other types.
UHMWPE material base formation mould 1 comprises UHMWPE material base extrusion molding die body 6 and UHMWPE material base extrusion molding core rod 7.As shown in fig. 1, UHMWPE material base extrusion molding die body 6 in this embodiment is cuboid (certainly, also can use other suitable shapes, such as cylindrical etc.), can be by the ultra-high molecular weight polyethylene melting charge of fusion plastification through shunting, enter in the UHMWPE material base extrusion molding core rod 7 of built-in one or more (quantity needs design according to technique).As required, described UHMWPE material base extrusion molding core rod 7 can laterally and/or longitudinally carry out array arrangement, to enhance productivity.Those skilled in the art know, and in the time that UHMWPE material base extrusion molding core rod 7 carries out array distribution, follow-up equipment also needs array distribution accordingly.As shown in Figure 1, UHMWPE material base extrusion molding core rod 7 is the fiber material base formation die cores that can be installed in UHMWPE material base extrusion molding die body 6.The runner of this formation die core presents taper shape, conical runner can make the compound of molten condition that distribution of orientations occurs in flow process, UHMWPE molecule streamwise is distributed, the coning angle of conical runner is generally designed to 25 ~ 40 °, is conducive to so large molecule streamwise and distributes.UHMWPE material base extrusion molding core rod 7 has columniform runner in mouth mould section.Columniform runner needs to be designed to different bore different lengths according to technique, general length is 50 ~ 100mm, and compound can be quickly heated up to the heater of high temperature (statement of TRANSIENT HIGH TEMPERATURE seem not meet common custom) in this port mould forming section setting, heating-up temperature general control is at 300 ~ 350 DEG C.Processing aid in compound precipitate into fiber surface under the effect of high temperature and orientation stretching, is more conducive to the orientation stretching of fiber.Due to high power heating at short notice, can avoid plastics to degrade simultaneously.
The modified assembly 4 of UHMWPE material base is mounted in the temperature-adjusting device after UHMWPE material base formation mould 1.This device will carry out UHMWPE material base cooling, be similar to an insulating box, be circulated and will be regulated temperature by cold air, can be used for regulating in process of production the temperature of extruding material base.This device can be very easy carry out dismounting, the length of this device is adjustable, be convenient to material base under different speeds of production by adjusting material base modified length, thereby required appropriate technological parameter when obtaining material base and entering UHMWPE material base draw forming and surface and apply mould 2.The modified length 13 of material base regulates according to speed of production, and length is generally 1-4 rice.UHMWPE material base also carries out predraft carry out thermoregulator process in the modified assembly 4 of UHMWPE material base in, makes UHMWPE fiber generation preorientation, and then improves the final strength of fiber.The degree of predraft is set according to the requirement of final products.Refining temperature general control, at 100-230 DEG C, finally should be able to ensure that fiber material base reaches viscoelastic state in the time entering UHMWPE material base draw forming and the deposited mould 2 in surface, to carry out follow-up processing.
UHMWPE material base draw forming and surface are applied mould 2 and are comprised that UHMWPE material base draw forming core rod 8 and UHMWPE material base draw forming and surface apply die body 9.It realizes two step functions: first by the UHMWPE material base through modified, through UHMWPE material base draw forming core rod, 8 drawing-offs make UHMWPE material base become the fiber with certain degree of orientation, because drafting process attenuates material base, it is coarse that material base surface can become, at this moment polythene material is melt extruded and is entered the deposited melt flow channel 12 of moulding of UHMWPE fiber surface by the second extruder, be coated on UHMWPE fiber surface, form and there is certain thickness polyethylene coating.The bore of this runner 12 can need to be designed to corresponding bore according to technique, thus the fiber predraft material base that obtains setting fibre diameter and set coating layer thickness.
Subsequently, the fiber predraft material base after coating enters into spinning assembly 5, for further processing according to conventional melt-spinning technology, thereby becomes the UHMWPE fiber with easy melting interface.Because spinning assembly 5 is well-known parts in field, its structure and effect do not repeat them here.
The technological process corresponding with the said equipment can simplified summary be: after ultrahigh molecular weight polyethylene powder or pellet mix with appropriate processing aid as raw material, send into the first extruder in UNMWPE extrusion molding main frame assembly 3, after conveying, compacting and heating, extruded by the first extruder successively.The compound of the fusing point state of extruding from the first extruder high pressure enters UHMWPE material base formation mould 2, forms ultra-high molecular weight polyethylene fused fiber material base at the spinning nozzle of material base formation mould.The High molecular weight polyethylene fused fiber material base of melting enters in the modified assembly 4 of UHMWPE material base, after modified homogenizing, the draw forming and the surface that enter tapered contraction are applied in mould 2, make fiber material base orientation stretching, simultaneously, by common molecular weight polyethylene raw material plastifying fusion, enter the deposited mould 2 in draw forming and surface by the second extruder, be attached on ultra-high molecular weight polyethylene melting material base surface at a mouth mould place for the deposited mould of draw forming and surface.The fiber material base that is attached with low molecular weight polyethylene material carries out orientation stretching under the tractive of spinning assembly 5, completes the superhigh molecular weight polyethylene fibers production with easy fused interface.
