1. The method that head is moulded in the electrical detonator insulation is produced in the waste high pressure polyethylene recycle, it is characterized in that:

  • get waste high pressure polyethylene (primacord waste material), after pulverizing, boiling, rinsing, screening, oven dry;

    Add whiteruss, its weightmeasurement ratio is 1;

    4-6, forms mixture;

    Mixture is mixed with new high-pressure polyethylene, weight ratio is 2-3;

    1 again;

    Send into the injection moulding machine injection moulding again, produce electrical detonator insulating plastics head, its injection temperature is 150 ℃

    -160 ℃
