발포 플라스틱의 제조 방법
[도면의 간단한 설명]
본 발명은 첨부된 도면을 참고로하여 하기에 더욱더 상세히 설명될 것이다.
제1 및 2도는 상기의 a) 내지 g) 단계를 수행하기 위한 2가지 가능한 장치를 도시한다.
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음

Claims (1)

  1. a) 원료물질들을 플라스틱 가공처리 장치에 공급하는 단계로 구성된 발포제 및, 임의로 다른 반응 조절제 및 첨가제를 포함하는 플라스틱 화합물로 부터 발포 플라스틱재료를 연속식 또는 반연속식으로 제조하는 방법에 있어서, b) 압력 제거시에만 발포화합물이 제조되도록 하는 온도 및 압력조건하의 플라스틱 가공처리 장치중에서 원료물질을 배합하고, c) 플라스틱 화합물을 냉각지대에 직접 이동시키고, d) 냉각지대에서의 화합물을 높은 점도 및 경도를 가지며 상류를 향한 압력성분에 의해 형성된 압력 하에서 거의 일정한 속도분포를 갖는 연속적인 원료로 냉각시키고, e) 임의로, 제동-보유 지대에 이동시키고, f) 상류에 위치한 지대에서의 플라스틱 화합물의 압력이 플라스틱 화합물의 발포를 방해하는 데에 충분하게 될때까지 상류를 향한 압력성분을 구조화하고, 그리고 g) 가열/발포/성형지대에 이동시킨 후 상기 화합물을 원하는 밀도로 발포시키기 위해 조절하는 단계들을 구성됨을 특징으로 하는 플라스틱 화합물로 부터 발포 플라스틱 재료를 연속식 또는 반연속식으로 제조하는 방법.
