It is please referred to shown in Fig. 8 to Figure 11 again, the mixed organization 10 ' provided in the second preferred embodiment of the invention, Main technology contents be it is identical as taken off person in aforementioned first preferred embodiment, do not exist together be second preferably implement It is to make the combined structure of the confluence part 30 ' and the mixer element 50 ' be different from the first preferred embodiment to be taken off in example.

Specifically, be in the present embodiment combine the body portion 51 ' of the mixer element 50 ' in the confluence part 30 ' directly, and It is to be fixed in the radial side in the body portion 51 ' with the binding members such as bolt (not showing on figure) via the combined cover 38 ' of a scalariform and be somebody's turn to do On First body 311 ', and the pan feeding runner 53 ' is made to radially extend and pass through from the hole wall in the mixing space 52 ' in straight hole shape Wear the portion 51 ', and with provide in 53 ' coaxial communication of runner should be gone out on the combined cover 56 ', to make the confluence space 32 ' The supercritical fluid and macromolecule molten mass of middle confluence are able to go out via this runner 53 ' and the pan feeding runner 53 ' by mixing sky Between mixed in 52 ' the radial inflow mixing space 52 ', and be different from as the first preferred embodiment by axially into structure It makes.

In other words, the combination between the mixer element 50 ', the confluence part 30 ' and the material feeding extremity piece 60 ' is to make the material feeding extremity piece 60 ' are located at the axis of a cylinder both ends in body portion 51 ' with the power part 55 ', and the confluence part 30 ' is made to be located at the radial side in the body portion 51 ' On, and it is different from taken off person in the first preferred embodiment, however, the change of the relative tertiary location, has no effect on the present embodiment The identical effect that can reach with the first preferred embodiment can be reached.

Followed by, the present invention is to be then a kind of mixed method, and can be with above-mentioned first disclosed by third preferred embodiment Mixed organization disclosed in case is implemented before preferred embodiment, the second preferred embodiment or aforementioned patent, specifically, the mixing The main technical characteristic of method is that macromolecule raw material molten mass and supercritical fluid is made alternately to enter same remittance in different time It is excessive to avoid the pressure in the confluence space in fluid space, and its specific step then includes:

A. stop supercritical fluid enter the confluence space when, with one first power make the macromolecule raw material molten mass via One first air stream enter runner enters in the confluence space.

B. when the macromolecule raw material molten mass is after step a flows into the predetermined amount in the confluence space, then stop the high score Sub- raw material molten mass is gone successively to.

C. former supercritical fluid for stopping flowing being made with one second power, flows into the confluence space via one second air stream enter runner In.

D. repeatedly implementation steps a to step c.

E. the macromolecule raw material molten mass and supercritical fluid being located in the confluence space, are to flow into one outward after confluence In the mixing space being connected to the confluence space.

F. the macromolecule raw material molten mass entered in the mixing space is mixed with supercritical fluid, makes equal Raw material supply source after the solution of matter, as external processing device.

Wherein, when step b is implemented, due to stopped going successively to for macromolecule raw material molten mass, meanwhile, it is present in Macromolecule raw material molten mass in the confluence space is still sustainably flowed out outward to enter the mixing space, and can reduce this Pressure in confluence space, in this way, be somebody's turn to do to get to reduce enter the supercritical fluid when step c is implemented Second power in confluence space, and make the pressure reduction of the confluence space interior, to reduce the influence of high pressure effect.

More specifically, the supply of first power can be as taken off in case before two preferred embodiments of the invention or aforementioned patent The spinning motion of crowded cylinder internal screw provided, but the construction is in the well-known technique belonged in known ejaculator or extruder Hold, this case simultaneously no longer needs to add superfluous words, specifically, the screw rod is using bar axis as axis along a first party when step a is implemented To (such as clockwise) rotated to form first power, and so that solid macromolecule raw material is squeezed cylinder via this and supplied Thermal energy be melt into flowable molten mass after, continue by first power promotion, and enter the confluence space in.

And when step b is implemented, in addition to the rotation that merely can stop the screw rod, it can also further make the screw rod along anti- It is rotated to the second direction (such as counterclockwise) in the first direction to form one reversed with first power the Three power, the difference between the two are as follows: the former is only to stop the promotion of first power to the macromolecule molten mass, not yet enters the confluence Macromolecule molten mass in space is the state for being able to stop to have entered the macromolecule molten mass in the confluence space and generating adverse current, And due to lower second power of demand, the supercritical fluid entered in step c will be not easy toward elevated pressures Cylinder direction adverse current is squeezed, and can avoid missing described in derivative prior art；And described in the latter, macromolecule is melted with the third power When body applies reversal interlocking relay, such as again along one circle of second direction rotation after three circle of first direction rotation, hereat, to avoid Entered macromolecule molten mass in the confluence space and generated adverse current, can as disclosed herein two preferred embodiments mention The pressure for being provided with the unidirectional flow passage configuration based on check valve, being avoided, and can be greatly reduced in the confluence space, compared to Merely stop second power effect, apply the third power it is expectable ground can further reduce it is required to second power Intensity.
