Embodiment Construction
[0016] Below in conjunction with specific embodiment the present invention is described in further detail:
[0017] In the shown embodiment, a kind of cable core insulating layer pushing method comprises the following steps:
[0018] 1. Put the polytetrafluoroethylene powder and the propulsion aid into the mixing bottle for mixing;
[0019] 2. The mixing bottle after mixing is placed in a rolling storage step at 25-27°C;
[0020] 3. The compacting step of pre-pressing the mixed material into a billet;
[0021] 4. After the billet is preformed, the inner conductor layer and the billet are loaded into the barrel of the extruder to carry out the extrusion step of cold extrusion and extrusion;
[0022] 5. The sintering step of introducing the extruded cable core with an insulating layer into the sintering equipment through the traction equipment for sintering;
[0023] 6. After the sintering is completed, carry out the cooling step of fan cooling.
[0024] Further, a drying st...
