Abstract

본 발명은 블록 발포체 설비의 컨베이어 벨트상에 포말을 적용하고 이 포말은 하부 컨베이어 벨트상에 사실상 수직으로 자유 낙하하고 컨베이어 벨트의 이동 방향과 반대 방향으로 포말이 유동하는 것은 컨베이어 벨트상에 횡방향으로 배치된 사실상 수직인 고정 장벽에 의해 방지되는 폴리우레탄 발포체를 제조하기 위한 방법 및 장치에 관한 것이다.

Claims (3)

  1. a) 포말이 사실상 수직으로 자유 낙하하는 것을 특징으로 하는, 블록 발포체 설비의 컨베이어 벨트상에 상기 포말을 적용하는 단계; 및 b) 상기 컨베이어 벨트상에 횡방향으로 사실상 수직인 장벽을 배치하여 상기 포말이 상기 컨베이어 벨트의 이동 방향과 반대 방향으로 유동하는 것을 방지하는 단계를 포함하는 폴리우레탄 발포체의 제조 방법.
  2. 제1항에 있어서, 상기 포말이 상기 컨베이어 벨트에 대해 직각으로 상기 컨베이어 벨트 폭의 20% 미만으로 연장되는 발포 장치에서 발생되고; 상기 발포 장치는 감압 유닛으로서 디자인되고 사실장 대칭인 원형 형상인 방법.
  3. a) 컨베이어 벨트를 가지는 연속 블록 발포체 설비; b) 상기 컨베이어 벨트의 위에 위치하여 폴리우레탄 액상 포말을 적용점에 공급하는, 사실상 수직으로 하향 배향된 출구를 포함하는 장치; 및 c) 상기 컨베이어 벨트의 이동 방향에 대해 상기 포말에 대한 상기 적용점의 후방으로 배치되고 상기 컨베이어 벨트를 가로질러 연장되는 사실상 수직인 장벽을 포함하는 폴리우레탄 발포체의 제조 장치.
