Description
Technical field
The present invention relates to textile chemical fiber spining technology field, and in particular to a kind of Mixing of Polymer Melt tower.
Background technology
The BP of 1845 is come from the earliest record of melt spinning process.Nineteen thirty-nine melt spinning is as manufacture nylon
The production technology of 66 fibers obtains industrial applications.Melt spinning basic process include material melts, from spinneret micropore extrusion,
Melt stream cooling and solidifying shaping.Manufactured long filament can be used bobbin coiling and molding or carry out other processing.In melt spinning
During, polymer feeding extruder, it is tired to be sent to metering further along after screw rod transmission, plasticizing, melting:Metering is poly- to pass through essence
Really metering ensures that the melt of polymer can be flowed into stable and uniform in critical component filament spinning component, the melt in filament spinning component
By the filtering of filter medium, eliminating to be provided with porous spinneret by high pressure press-in after impurity and bubble turns into thread；Carefully
Stream is while cooling (quenching) quick by horizontal blowing, because the effect of following wireline reel also produces super drawing so that diameter
Attenuate；As-spun fibre is wound into certain package.
Under normal circumstances filament spinning component be mainly be made up of upper strata excessively stream lid, wire netting and filter sand filter layer, distribution plate and
Porous spinneret is formed.Spinning melt is after top-level entries flow into filament spinning component, the mistake for type of being lain prone via the back taper minister in ancient times in sand chamber
Stream lid diffusely enters in the inner chamber of component, and filtration combination layer is ingeniously entered in the presence of upper stressor layer.Filter layer generally has multilayer
Screen pack and METALLIC FILTRATION SAND composition.The a piece of coarse net for not luring steel wire to weave into often is laid in the superiors of filter layer, turns into cover net
Or cover net, it is therefore an objective to which the debris for stopping bulk and the layer of sand for preventing bottom move.When being filtered using filter sand, in principle by sand grains
Granularity is carefully sequentially arranged by thick.When placing multistorey strainer mesh, and by the descending principle of mesh size.In filtration combination layer
The bottom laid one layer of supporting network, it be typically be made up of a piece of or two panels coarse net, it is therefore an objective to support upper level filter layer,
Increase longitudinal rigidity, have the function that not to be depressed, it can also prevent from draining to the effect of spinneret orifice under broken filter sand sometimes.By
Melt after fine filtering is flowed into the hole of distribution plate.On the one hand the effect of distribution plate is to play support upper level filter layer, another
Aspect is before polymer melt is assigned into spinneret plate as homogeneously as possible so that the uniform flow per hole, also tubing flow displacement filament plate
The melt pressure of part is shared so that spinning plate surface is unlikely to superpressure and deformed.Polymer melt is squeezed into spinneret
Guide hole after, micropore gives the certain shape of melt and is extruded as strand, finishes to dazzle body like this inside filament spinning component
The design of the filament spinning component of flowing need to mainly determine its structure snd size.Wherein component external structure snd size mainly need to examine
The problems such as considering the intensity and corrosion resistance of itself, the problem of also relating to installing/dismounting and sealing.The inside member of filament spinning component
Part just really carries main spinning function, it should how to select filtration combination element, hybrid element, distribution member and spinneret
Panel element etc., it is necessary to comprehensive to go fully to be calculated and considered from multi-angles such as hydrodynamics, melt rheology and heat conductions.
Certainly the problem of inner sealing of each element and strong rigidity can not be ignored while design.Melt spinning is to carry out at high temperature
, if polymer melt is chronically at high humidity state, it may occur that degraded influences the quality of precursor, and institute W is inside design component
During passage, melt should be made to be uniformly distributed in each micropore of spinneret as far as possible, channel resistance should be equal, can not exist in component
Dead angle, in case melt residence time is long and decomposes.It should process smooth with king's part surface of melt contacts, it is impossible to make thing
Material is detained due to wall surface resistance.Fluid motion uniformity mainly includes fluid motion speed, pressure, stop in filament spinning components
The contents such as time, discharging distribution.Preferable filament spinning component should be able to ensure that above-mentioned parameter is all identical simultaneously, and sample presentation just can ensure that
Polymer melt is evenly distributed in each spinneret orifice of spinneret with identical matter, and it is uniformly high-quality finally to spin out structural behaviour
Measure fiber.However, the factor for influenceing flow field uniformity in filament spinning component is numerous, wherein mainly having material properties, process conditions, setting
Standby structural parameters etc..When the above two control identical, device structure is its most important influence factor again.
The flow behavior of polymer melts is more complex compared with for small molecule solution.Under external force, melt is not only
Irreversible viscous yielding is shown, but also shows reversible elastic deformation.Because the flowing of polymer is not
Simple Relative sliding between macromolecular chain, but the overall result of moving cell transition successively.Under external force, macromolecular chain
Inevitably stretched along external force direction, remove external force, macromolecular chain will be spontaneously rolled up again.This conformation change
Caused elastically-deformable development and Recovery Process are relaxation, and the process depends on polymer molecular weight, external force acts on
Time, temperature etc..It is the outward appearance of elastic deformation and its subsequent lax pair fiber, dimensional stability, interior in molding process
Stress etc. has substantial connection.
High polymer molten viscosity is cut flowing and is mainly characterized in that:It is very high to cut viscosity；Viscosity strong depend-ence trimming speed is cut, absolutely
Most of high polymer moltens belong to pseudoplastic fluid；Velocity flow profile of the pseudoplastic behavior high polymer molten in pipe is not parabolically
It is linear, and plunger flow is close to, velocity gradient concentrates on near-wall, is moved that may have tube wall to slide in some cases,
Molecular-weight gradation effect is there may also be in flowing, low molecular weight fraction is more than pipe axle in near-wall.
It is not constant temperature process in actual production process, and is unstable state, but above-mentioned " spinnability " is theoretical, it is right
The forming process of chemical fibre still has preferably reference and directive significance, and the principal element drawn from " spinnability " in theoretical is all
It is the factor for controlling spinning to be smoothed out.Such as be viscosity and surface tension to capillary mechanism major influence factors, to cohesive energy
The principal element that failure mechanism influences is deformation speed and viscoplasticity size etc..Understanding the spinnability principle of melt contributes to us
When adjusting spinning technique, optimal conditions are targetedly selected, so as to avoid occurring wild effect in spinning.Change and spin
The rheological property of silk Wang Yi parameters and raw material may cause the variable element scope for stablizing spinning fully to increase, convenient and technique
Adjustment.
Because the high temperature polymer melt of melting needs to shift and flow, therefore, high-temperature fusant and spinning group in filament spinning component
Part quality inspection inevitably there are contact, adhesion on the inwall of filament spinning component also just inevitably be present, although
At present when preparing filament spinning component can by the smooth enough of its inwall processing, largely reduced due to
Inner wall surface problem and caused by attachment of polymers, still, due to the limitation of machining accuracy and process technology, it is difficult to accomplish inwall
It is completely smooth, still can so produces the adhesion of polymer；Also have in the prior art in spinning process in polymer and spinning
The scheme of lubricant is added between the inwall of component, can so play certain anti-adhesiving effect, but what these were added
Lubricant will certainly be entered in polymer, and then the property of polymer and the property of follow-up spinning produce unpredictable shadow
Ring, and it is worthless.Due to the adhesion of the polymer in spinning process, all needed after the production schedule of a batch is not completed
Filament spinning component thoroughly to be cleaned, the cleaning to filament spinning component can cause time and cost greatly to consume, but also
It is difficult to be cleaned that some dead angles, which can be there are, and follow-up production can be adversely affected again.Therefore, exploitation one is needed badly
The anti-adhesion of various pieces or anti-blocking techniques in kind new filament spinning component, the shortcomings that to overcome in the prior art.
