| titleOfInvention | Manufacture of foam insulation cable |
| abstract | PURPOSE: To secure formation of a high foam insulation cable by letting chemical foam agent of a high water absorption which generates gas by heat decomposition absorb a predetermined quantity of water, and setting the inner pressure of a hopper for storing it to be higher than the inner pressure of an extruder for equalizing heat mixture of resin with the foam agent in the extruder. n CONSTITUTION: A center conductor 1 from a winder is sent to an extruding head 3 of an extruder 2 where foam resin 4 is coated, and is cooled in a cooling tank 5 and then taken up. The extruder 2 is of a two-stage constitution, and material pellets charged into a hopper 6 are sent to a first stage extruding mechanism 7 including a screw feeder 9 where they are heated and mixed, they are sent to a second extruding mechanism 8 and reheated, and they are supplied to an extruding head 3. The material pellets include chemical foam agent which generates gas by heat decomposition, and nuclear agent such as zeolite and silica gel having a water absorption of about 0.3-1.0wt.% is added to it. The inner pressure of the hopper 6 for storing resin is set higher than the inner pressure of the extruding mechanism 7, and a sufficient quantity of water for a foam agent is given to the resin. n COPYRIGHT: (C)1991,JPO&Japio |
