Embodiment Construction
[0020] like figure 2 As shown, the present invention provides an extruder, which includes a first-stage extruder 1 and a second-stage extruder 2, the first-stage extruder 1 is a twin-screw extruder, and the second-stage extruder 2 It is a single-screw extruder, the first-stage extruder has a first material inlet 3 and a first material outlet 4, the second extruder has a second material inlet 5 and a second material outlet 6, and the first The material outlet 4 is connected to the second material inlet 5 . Preferably, the diameter-to-length ratio of the first-stage extruder is 1:45, and the diameter-to-length ratio of the second-stage extruder is 1:65. Of course, the diameter-to-length ratio can be changed according to requirements. Above-mentioned twin-screw extruder and single-screw extruder are existing equipment. The invention combines the two, the equipment modification is simple and quick, and the effect of chain extension is quite different, which is an innovation to...
