The double screw extruder, screw slenderness ratio is 25：1, the workflow of double screw extruder order is：Feed(raw material)inlet, One area DEG C, 2nd area, 3rd area, 4th area, 5th area, flange and head；Granulate the entrance double screw extruder from feed(raw material)inlet, an area Temperature 130 ± 5, the material for mixing enters in machine barrel from loading hopper, and due to the effect of temperature, material is started preheating and many Remaining gas is discharged from charge door；Two 150 ± 5 DEG C of area's temperature, three 160 ± 5 DEG C of area's temperature, in 2nd area and 3rd area, due to temperature The effect of degree, is compressed by the rotation of screw rod, and plastic molten condition is become by the material for preheating；Four area's temperature 165 ± 5 DEG C, five 170 ± 5 DEG C of area's temperature in four He Wu areas of area, keep material melt adhesive temperature uniform and stabilization molten condition；Flange 170 ± 5 DEG C of temperature, in flange, screw rod rotation produces thrust, and makes plastics fine and close by porous filter plate and plastify pressure Real to ensure plasticizing effect, the temperature of Simultaneous Stabilization ensures that plastics smoothly enter head；175 ± 5 DEG C of head temperature, nose region makes Material is kept molten by, while making the insulating materials surfacing of final preparation smooth；
The insulating materials that will be prepared is produced for cable, prepares the fire-retardant resistance to daylight self-lubricating cable of house wiring.
