Description
Technical field
The present invention relates to a kind of face shearing plasticizing method and devices, and in particular to uses pectination butt muff mill forming face
Shearing grinding, achievees the purpose that efficiently to be plasticized, and belongs to polymer material molding processing technique field.
Background technique
Plasticizing quality is well the prerequisite of all polymer material molding processing.Traditional plasticizing method has two rollers to open
Refining, mixing, single screw rod or twin-screw mixer, basic plasticizing principle are that material is forced to form spatial variations, are generated to material
Shearing is mediated, is pulled, the immixture of place-exchange.Namely pull shearing and be squeezed and deformed and mediate, plasticizing cut mode is not
It is face shearing, common problem is that shear action is weak, and mixing dispersion is bad.
Occur earliest and the open mill used till today always, the basic principle is that two have speed difference, it is open
Roller is close together to form a linear narrow slit, and material is dragged under the differential of roller and rubbing action and passes through above-mentioned line
Shape narrow slit, material are extruded in narrow slit, and volume becomes smaller, and are formed and are pulled shearing, then carry out tumble mixed by hand.Therefore mill
The plasticization mechanism of machine is to pull shearing and be squeezed and deformed to mediate, the disadvantage is that mixing efficiency is low, system is not closed, lacks pure-surface
Strong shear effect.
Mixer is poor for mixing (mixed essence is material place-exchange) ability of open mill, and system is not closed to be lacked
Two rollers are changed to Z-type class rotor and are placed in closed container with being staggered by point, due to two Z-type class rotor shapes
On be staggered, form spatial variations when it is rotated, material generated and mediates, pull, the immixture of place-exchange.It is newly-increased
Closed container and the outer ring of Z-type rotor constitute linear narrow slit and can produce certain shearing, due to rotor be changed to it is Z-shaped, with mill
The pure circle cylinder of machine is compared, and the linear narrow slit of mixer is shorter, and shearing is weaker than open mill, and plasticizing effect is not so good as open mill, work
Pressure is extremely low.In summary, the common drawback of open mill and mixer be can not continuous discharge.
Screw extruder by screw rod rotate, the material in its screw channel is conveyed, using in material transportation process with
The speed difference that static material tube inner wall is formed generates towed shearing, realizes continuity plasticizing.It is also carried out around screw extruder
Various improvement make spiral groove depth gradual change such as to generate volume compression, have been developed the double screw extruder with kneading elements, but
It is that there is no essential variations for the basic structure of screw rod or kneading --- it mediates, towed shearing plasticizing, plasticizing pressure is only
30MPa。
Injector generally uses spreader or short screw to be plasticized, and plasticizing quality is poor.Chinese patent
CN201310402782.7 discloses " a kind of Novel grinding disc extruder being blended for trace material ", and principle is screw rod one end
Increase a mill and realize face shearing plasticizing, the disadvantage is that the too small then resistance in mill gap is big, mill gap is increased, then is plasticized difference；
Chinese patent CN201410004634.4 discloses a kind of " series connected type grinding disc extrusion of the not equal gaps screw channel volume variation of reducing
Machine ", it is the screw rod series connection using two sections of different-diameters, mill of the leading portion major diameter screw rod with face shearing plasticizing, using differing
Screw channel volume variation in gap is plasticized, the disadvantage is that two sections of screw rod series connection, axial dimension is too big, stop of the material in barrel
Time is too long, is easy to be thermally decomposed for a long time.
Zhou Haiying etc. discloses " a kind of taper rubbing disc extruder " in periodical " Chinese Plastics " (2006,07:65-68),
Its shortcoming is there is a problem of that mill gap resistance is big.
Chinese patent CN201010218180 discloses a kind of " combined impeller abrasive disk type extrusion plasticizing method and device ",
Basic principle is face shearing plasticizing to be realized using the discoid plane mill of multiple groups, and be provided with blade wheel structure, grinds each group
Disk forms inter-layer passages between gap, reduces the resistance in mill gap, increases the mixing of material.The disadvantage is that: if wanted
The area for increasing mill shear surface, needs to increase the diameter of mill, this will lead to the increase of mill face axial compressive force, if do not increased
Add axial compressive force, then can reduce the pressure (compressive load per unit area) of material in mill gap, on the other hand structure mill assembling
And maintenance is very inconvenient, and it is very high to the required precision of assembly, increase maintenance cost.
