1P-373 알루미늄 합금 절삭가공용 변성 PAG 합성유 개발에 관한 연구
홍진숙,정근우,김영운,공호열 한국공업화학회 2017 한국공업화학회 연구논문 초록집 Vol.2017 No.1
평균 분자량이 500~2000 인 공업용 폴리 알켄글리콜(PAG)을 원료로 하여 말단에 세바식산을 축합 반응하여 PAG-ester를 합성하거나 carbonate, methoxy, phosphorus 등 다양한 관능기를 도입하여 변성 PAG를 합성하였다. 합성된 변성 PAG에스테르는 NMR 및 GPC로 구조와 분자량을 확인하였고 유제로서의 금속과의 표면특성을 관찰하기 위해 표면장력과 접촉각을 측정하였다. 또한 torque 시험기를 이용하여 변성 PAG의 절삭 성능을 평가하였다.

The identification of power flow in dynamically loaded structures Is essential in the analysis of structure-borne noise. However there are no general purpose tools to estimate powers flow. To make matters worse. It is very difficult to measure it. The power flow can be formulated in terms of balance forces(ELFORCE) at each element and velocities at the associated node obtained with MSC/NASTHAN. In this paper the procedure which is consist of the computations of the balance forces of al1 elements and the velocities at all nodes using MSC/NASTRAN. The calculations of the power f1ow at each element using PCL(PATRAN Command Language) and the Preparation of post -processes is set UP.

The purpose of this study was to develop a recipe for high quality Yackwa (fried cake made of wheat flour) by adjusting the mixing ratio of flours, frying temperature and time. Yackwas were prepared by using 3 kinds of flour mix (3:7, 4:6, and 2:8 of weak to medium ratio), fried at various temperatures and times, and evaluated by mechanical characteristics and sensory evaluation. It was found that Yackwa prepared with 3:7 mixing ratio of flour and fried at 160℃ for 9 min was most preferred. Yackwas with the same flour mixing ratio and fried at 150∼155℃ for 12∼16 min were also within the range of acceptance. The characteristics of desirable Yackwa were suggested to be soft, crispy, and to have little taste of oil.
