Claims (11)
- 수성 분산액 또는 용액을 향류식 원리에 의해 유동화 챔버의 개스 스트림속으로 분무시켜 유동화시키고, 시동단계(start-up phase)로 최대 개스흐름의 10 내지 60% 및 분산액 또는 용액의 최대 공급속도의 단지 30%이하에서 과립의 형성공정을 개시시키며, 이어서 공급속도 및 개스흐름을 공급속도 및 개스흐름에 대한 최대값까지 증가시키고, 본가동단계(main phase)로 최대 개스흐름 및 최대 공급속도에서 과립의 형성 공정을 계속시킴을 포함하여, 고형물의 수성 분산액 또는 용액(경우에 따라서는, 또한 제형화 보조제를 함유함)으로부터 수분산성 과립을 제조하는 방법.
- 제1항에 있어서, 상기 과립의 형성공정을 시동단계로 최대 개스흐름의 40내지 50% 및 분산액 또는 용액의 최대 공급속도의 5내지 15%에서 시작하는 방법.
- 제1항 또는 제2항에 있어서, 유동화 챔버속으로 유입되는 지점에서의 개스스트림의 온도가 90 내지 180℃ 특히 120내지 150℃의 범위인 방법.
- 제1항 내지 제3항중 어느 한 항에 있어서, 유동화 챔버속으로 유입되기 전의 개스 스트림이 공정 수행도중 일정한 온도를 갖는 방법.
- 제1항 내지 제4항중 어느 한 항에 있어서, 상기 시동단계에서의 공급속도를 형성된 과립의 온도(t)가 (tm+20℃) 내지 (tm-20℃)(여기서, tm은 온도의 평균값(℃)이다)의 범위로 유지되도록 하는 속도로 실질적으로 개스흐름과 동시에 증가시키는 방법.
- 제1항 내지 제5항중 어느 한 항에 있어서, 상기 시동단계에서의 공급속도를 0.1분 내지 4분 사이클로 사이클당 최대 공급속도의 1내지 5%씩 증가시키거나, 시동단계에서의 공급속도를 연속적으로 증가시키는 방법.
- 제1항 내지 제6항중 어느 한 항에 있어서, 개스 스트림에 의해 운반된 미세 과립 및 분진을 하향류(down stream)식으로 놓인 필터에 의해 트래핑 시킨 다음, 필터를 공정수행도중에 연속적으로 또는 일정한 시간간격으로 진동(shaking)시켜 트래핑된 과립 또는 분진을 유동화 챔버속으로 낙하시키거나 운반하는 방법.
- 제1항 내지 제7항중 어느 한 항에 있어서, 경우에 따라서는 농약 및 과립용의 통상적인 제형화 보조제의 존재하에, 분산액 또는 용액중에 각각 분산되거나 용해된 고체가 농약을 포함하는 그룹에 속하는 활성 화합물인 방법.
- 제1항 내지 제8항중 어느 한 항에 있어서, 상기 분산액 또는 용액이 과립의 형성에 도움을 주는 접착제, 점착 부여제, 습윤제, 분산제 및 안정화제를 하나 이상 함유하는 방법.
- 제1항 내지 제9항중 어느 한 항에서 청구된 바와 같은 방법에 의해 제조된 수분산성 과립.
- 제8항에서 청구된 바와 같은 방법에 의해 제조된 과립의 식물보호제 또는 해충방제제로서 용도.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
