Polymer Additives as Mist Suppressants in Metalworking Fluids Part I: Laboratory and Plant Studies - Straight Mineral Oil Fluids 950245

Ambient oil mist levels in automotive manufacturing plants where coolant is used as a metalworking fluid is an on-going concern, in particular, its effect on worker's breathing zone air quality. To find a means suppressing oil mist from being generated during these operations was studied in the laboratory, where several polymer additives were analyzed. It was found that a small amount (less than 100 ppm) of polyisobutylene (PIB) was extremely effective in suppressing mist formation by increasing the oil droplet size of typical straight mineral oil aerosols generated. Subsequent plant pilot tests confirmed these results, yielding 70-90% oil mist reductions using only 20-100 ppm PIB additions. In addition, no adverse impact was observed on the machined part quality.
