Abstract
Description
DE 196 35 706 A1으로부터 고점도(high-viscosity) 중합체 용융물의 가소화, 여과, 정량 주입 및 이송 방법이 공지되어 있으며, 이 명세서에서는 용융물이 가소화되지 않은 상태로 연속 용융물 스트립으로서 기어 펌프에 공급되어, 상기 기어 펌프에 의해 흡입된다. 여기서 기어 펌프는 용융물의 흡입 및 예비 가소화에 사용되고, 용융물의 정량 주입에는 사용되지 않는다. 그런 다음 상기 용융물이 거의 가소화된 상태에서 가소화를 수행하는 스크류 머신으로 전달된다. 그러나 이 경우, 용융물 온도가 기어 펌프의 개수에 의해서만 조절될 수 있고, 용융물 스트립에 균열이 생기면 상기 용융물 스트립을 다시 수작업으로 기어 펌프 내에 삽입해야만 하는 단점이 있다.
EP 1 080 863 A1으로부터 고무 혼합물을 처리하기 위한 스크류 압출기와 기어식 압출기의 직렬 접속이 공지되어 있다. 이러한 직렬 접속에서는 재료의 가소화가 기어식 압출기에 의해 완전히 실시되는 반면, 스크류 압출기는 오로지 재료 공급에만 사용되며 고유의 가소화 구역을 갖지는 않는다.
Claims (5)
- 이축 스크류 압출기를 사용하여 고무 혼합물을 연속 제조하기 위한 방법으로서, 상기 고무 화합물이 쇼트 스크류 압출기(short-screw extruder)(5) 내에서 가소화되고, 기어 펌프(3)를 통해 미리 정해진 온도 및 미리 정해진 체적 유량으로 이축 스크류 압출기에 공급되며, 상기 기어 펌프(3)의 유입측은 쇼트 스크류 압출기(5)에 연결되고, 배출측은 이축 스크류 압출기(2)의 유입측으로 직접 연결되는, 고무 혼합물의 연속 제조 방법.
- 제 1항에 있어서, 상기 기어 펌프(3)와 상기 쇼트 스크류 펌프(5)가 각각 독립적으로 제어 가능하게 구동되는 것을 특징으로 하는, 고무 혼합물의 연속 제조 방법.
- 제 1항 또는 제 2항에 있어서, 출발 재료로서 스트립 형태로 절단된 고무 베일(rubber bale)이 사용되는 것을 특징으로 하는, 고무 혼합물의 연속 제조 방법.
- 제 1항 또는 제 2항에 따른 방법을 실시하기 위한 장치에 있어서,압출될 재료의 유입구(7)를 구비한 쇼트 스크류 압출기(5),유입측은 쇼트 스크류 압출기(5)와 연결되고, 배출측은 이축 스크류 압출기(2)의 유입측에 직접 연결되는 기어 펌프(3), 및기어 펌프(3) 및 쇼트 스크류 압출기(5)를 위한 각각 별도로 제어 가능한 구동 장치(4;6)를 포함하는, 고무 혼합물의 연속 제조 방법을 실시하기 위한 장치.
- 제 4항에 있어서, 기어 펌프(3)의 배출구가, 상기 기어 펌프의 맞물림부의 외부 직경이 이축 스크류 압출기의 스크류의 외측 맞물림부와 최소의 거리를 두고 이격되도록 이축 스크류 압출기(2)의 유입구에 연결되는 것을 특징으로 하는, 고무 혼합물의 연속 제조 방법을 실시하기 위한 장치.
