Description
Claims (4)
- 주압출기(2)에서 중공부(10)가 형성된 프로파일(3)을 공급하여 냉각장치(4)를 통과시킨 후 와인더장치(5)에서 프로파일(3)의 사이에 보조압출기(6)로부터 연결수지(12)가 공급되어 합성수지관(1)을 성형함에 있어서,상기 합성수지관(1)의 성형시에 일측으로 편수칼라(15)가 동시에 성형되며 합성수지관(1)의 표면 전체면에 감마선이 조사되어 가교된 표면처리층(13)을 갖도록 함을 특징으로 하는 연소방지와 강도가 향상된 합성수지관.
- 주압출기(2)에서 중공부(10)가 형성된 프로파일(3)을 공급하여 냉각장치(4)를 통과시킨 후 와인더장치(5)에서 프로파일(3)의 사이에 보조압출기(6)로부터 연결수지(12)가 공급되어 합성수지관(1)을 제조함에 있어서,상기 합성수지관(1)이 성형되면서 공급되는 과정에서 조사장치(8)를 통과하면서 감마선이 조사되어 합성수지관(1)의 표면 또는 내경에 가교가 이루어진 표면처리층(13)이 성형되도록 하는 조사과정과,합성수지관(1)의 표면 또는 내경에 가교가 이루어진 후 일정한 규격으로 절단장치(9)에서 절단하여 합성수지관(1)이 제조됨을 특징으로 하는 연소방지 합성수지관의 제조방법.
- 제2항에 있어서, 합성수지관(1)이 성형되는 과정에서 합성수지를 공급하여 합성수지관(1)의 일측으로 편수칼라(15)가 성형되어 조사과정에 공급되도록 함을 특징으로 하는 연소방지 합성수지관의 제조방법.
- 제2항에 있어서, 합성수지관(1)의 외측으로 보조압출기(16)를 통하여 외피층(14)을 성형한 후 감마선을 조사하여 외피층(14)에 표면처리층(13)이 성형됨을 특징으로 하는 연소방지와 강도가 향상된 합성수지관의 제조방법.
