초록
산업체에서 부품을 가공하거나 완성품을 제조하는 과정에서 세정 공정은 필수적으로 사용하고 있고 현재 국내외 대부분의 제조업체에서는 오존파괴물질인 CFC-113이나 1,1,1-TCE 대신에 보다 환경친화적인 수계 세정제로의 대체가 진행중이다. 그러나 수계 세정시스템은 세정공정이나 헹굼공정에서 다량의 물을 사용하기 때문에 많은 폐수를 발생시키는 단점이 있다. 따라서 수계 세정시스템에서는 이러한 발생을 최소화하고 세정액과 헹굼수의 성능을 오랫동안 유지시키기 위한 모니터링 기술과 재활용 기술의 도입이 긴요하다. 본고에서는 수계 세정시스템에 사용하는 세정제와 주요 오염물질인 절삭유를 조사 분석하였고 산업현장에서 도입 가능한 수계 세정시스템의 모니터링 기술과 재활용 기술 등을 분석 평가하였다.
Cleaning process is necessary for machining parts or manufacturing finished products in the industry. Most of domestic and foreign companies are now trying to adopt environment-friendly aqueous cleaning agents instead of CFC-113 and 1,1,1-TCE which are ozone-depleting substances. However, the aqueous cleaning system has a disadvantage due to its generation of lots of waste water since the system utilizes water in cleaning and rinsing processes. Thus, it is very important that monitoring and recycling technologies of the cleaning solution and the rinse water should be introduced in the aqueous cleaning system in order to minimize generation of waste water and to maintain its cleaning performance for a quite long time. In this paper, the cleaning agents utilized in the aqueous cleaning system and cutting oils which are main contaminants were examined and analyzed. And the monitoring and recycling technologies of the aqueous cleaning system which can be employed in the industrial fields were also reviewed and evaluated.
