A Practical Design of Environmental Conscious Coolant Recycling System

我们研究了无胺水溶性冷却剂多次循环使用的可能性。与含胺冷却液相比，循环无胺冷却液除防锈性能外，表现出良好的润滑和冷却性能。可以通过提高油浓度来改善锈蚀控制。此外，提出了一种利用红、绿、蓝三色LED灯的观察技术，作为一种无损检测油液浓度和浑浊度变化的方法。

We examined the possibility of multiple recycle use of amine-free water solublecoolants. The recycle amine free coolant showed an excellent lubricating and coolingperformance compared to the amine-containing coolant except for the rust control. Therust control can be improved by increasing the oil concentration. In addition, an observation technique using red, green and blue LED lights was proposed as a nondestructive measured method to detect the oil concentration and turbidity change.
