초록

벨 디스크(Bell disc, 오토마이저 Atomizer)를 사용한 회전식 도장기술은 뛰어난 도료 전달효율, 도장 패턴 및 입자크기의 균일성, 스프레이 건 방식에 비해 적은 압축공기 사용량 등의 장점이 있다. 또한 회전식 분무기는 모든 페인트 재료에 적용할 수 있고 자동차 연속도장 같은 대규모 도장이 필요한 환경에 적합하다. 도장기기의 성능과 밀접하게 관계된 도장품질은 벨 디스크 표면설계에 따른 액적 크기와 균일성에 의해 결정된다. 따라서 이번 연구는 도료의 점성, 밀도, 표면친화도 등의 염료 특성이 고려된 작동하는 벨 디스크의 회전수, 직경, 표면의 각도, 무화시의 박막두께에 대한 모델링을 시행하여 표면설계 방법의 기초를 수립하였다.
