영문 초록

Vapor pressure of MWF(Metalworking Fluids) is so low that they would not normally be thought to evaporate. However, MWF mist that dispersed into air has so great a surface area that evaporation can be appreciable. Based on thi s assumption , this study was conducted to determine if MWF loaded into PVC filter evaporates. MWF loaded into PVC filter lost 2.0% - 16.1 % of its original mass during desiccating. As air flowed into filter more longer, MWF lost was high. Loss range caused by airstream was 8.4% - 40.5 % of spiked mass. Loss from fresh MWF was more than that from used MWF. This fact means that evaporable components in used MWF were already lost. There was difference of MWF loss between Millipore and SKC manufacturers. Relationship between total MWF loss and flowing airstream time was statistically significant. Adjusted R-square was 96% - 97% in 3401 MWF and 75% - 79% in 570 L MWF. This results shows that total MWF loss and flowing airstream time is strongly related. Up to now, there is no a sampling method to estimate accurately worker s exposure to airborne MWF. Factor to correct loss caused during sampling including desiccating must be studied
