Further, described heating wires (4) is connected with the optional position of control panel (3); Heating wires (4) is connected with the optional position of barrel (2).
Further, the cross-sectional area of described heating collar (4) is 0.060-3.000mm
2.
Further, described heating collar (5) is made up of one deck sheath material (7) of ring-type copper cash (6) and ring-type copper cash outer wrapping thereof.
Further, the core material of described ring-type copper cash (6) is tinned wird.
Further, described tinned wird maximum outside diameter is 1.41mm.
Further, described sheath material (7) is Teflon, and insulation thickness is 0.30mm.
The melt temperature gap of bi-material is large, if perform with the single operation temperature of routine, as easy as rolling off a log cause the plasticizing of wherein a kind of material bad or degraded, such as processing temperature is set to PA66(280-300 degree) time, close to degradation temperature 300 degree, during production, easily there is the exceptions such as Jiao expects, aging in PA6.If when temperature being set to PA6 (230-250 degree), PA66 cannot plastify completely, easily there is the non-resinifying agents such as brilliant point in product surface, directly affects quality.The utility model, by multi-layer co-extruded structure, controls separately the temperature of every one deck, reduces the temperature difference to the impact of materials processing.PA66 content is more, spendable maximum temperature is higher, when PA66 content lower than less than 16.7 % by weight time, the maximum temperature of product cannot break through 180 DEG C because of the restriction of PA6 heatproof, when PA66 content higher than 75 % by weight time, because of processing temperature restriction, PA6 very easily degrades aging, and the physical property of product significantly declines.
The each interlayer of the utility model heats separately, reduces single heating temperature to the impact of composite bed different materials, promotes plasticizing quality, reduces apparent flaws and occurs.
Process equipment needs to do die bearing individual layer independent heating, and avoid the plasticizing of different materials under same processing temperature bad, this effectively can improve apparent flaws, improves the quality of products.
Described extruder comprises main frame, control panel, heating wires, the heating collar of material tube inner wall, described main frame is connected with extruder barrel, extruder barrel is connected with control panel, control panel is connected with heating wires, this heating wires is connected with extruder barrel, any position, the temperature of setup control panel is carried out according to the order added materials, (after first adding PA6 and additive, add PA66 and additive again, temperature bottom that is set to the heating-up temperature of PA6, last layer arranges the heating-up temperature of PA66) setting after first barrel itself is heated, after being all heated to the temperature that each material mates, start main frame, then start to heat material and extrude.
Heating collar is made up of one deck sheath material of ring-type copper cash and ring-type copper cash outer wrapping thereof; The core material of ring-type copper cash is tinned wird, and copper cash maximum outside diameter is 1.41mm, and sheath material is Teflon, and insulation thickness is 0.30mm, and the temperature that can bear is-100 DEG C-+350 DEG C;
It is 250 degree that PA6 heating collar arranges temperature classification, and it is 300 degree that PA66 heating ring arranges temperature classification.
Gained finished product is toasted 2 hours in 170-230 DEG C of environment, extremely occur without curling, melting, break etc., hot strength is between 75-85MPa, fracture rate is all greater than 300%, absolutely prove that the vacuum bag film of the utility model gained is high temperature resistant, the highest serviceability temperature of bearing 230C, meets most resin system forming requirements, far away higher than the limitation of existing composite membrane 120C.
