Abstract

A process programmable vacuum saturation system has been developed and tested, which is veryimportant process in the laboratory measurement of physical properties. It can program ON/OFF time of eachunits including a vacuum pump, a cold trap, two vacuum ovens, four small pumps and 10 valves to performthe vacuum saturation processes automatically. It can be saved as a template time table and can be reloadedto perform exactly the same process. Either dry-type or wet-type vacuum saturation can be programed andperformed. There’s no need to watch the system until the end of the process and manual operation is also possible,whenever needed, using the touch screen in the main front panel. One can adjust the vacuum pressure andtemperature using vacuum controller, which is not fully automated yet like several separate stand-alone units.Further development of the system is needed to upgrade toward the fully automated vacuum saturation system.

실내 물성 측정에서 매우 중요한 과정 중 하나인 시험편의 수포화 작업을 편리하게 수행할 수 있도록공정 프로그래머블 진공 수포화시스템을 개발하고 그 성능을 확인하였다. 개발된 시스템은 진공 펌프, 냉동수분포집조, 진공 오븐 두 개를 포함하고 4 개의 소형펌프와 10 개의 밸브, 각각의 ON/OFF 공정 시간을 프로그램할수 있고, 각 유닛의 시간표를 템플릿으로 생성하여 공정입력 파일로 저장하였다가 필요할 때 불러와서 자동제어로 구동할 수 있다. 또한, 습식 진공포화 공정 뿐 아니라 진공 효율이 좋다고 알려진 건식 진공포화 공정도소화하며 진공 수포화 작업의 시작으로부터 끝날 때까지의 전 과정에서 실험자의 감독이 필요하지 않으므로충분히 사용자의 편의를 보장한다. 필요에 따라서는 언제든지 수동 제어로 전환이 가능하고 터치스크린을 통한수동 운전도 가능하다. 또한, 이 시스템은 진공 조절기를 이용하여 진공 압력과 진공 시간의 조절이 가능한데,이 기능은 다른 몇가지 독립형(stand-alone) 장치들과 함께 아직 자동화되어 있지는 않다. 향후 지속적인 개선을통해서 더 발전된 형태 혹은 완전자동화된 형태의 진공 수포화시스템으로 발전될 수 있을 것으로 기대한다.
