Measurement of the performance of air cleaners against the particulate element of rosin-based solder flux fume

摘要

A number of commercially available air cleaners designed for use against solder fume have been examined. The fume capture efficiencies have been measured with a tracer gas comprising a neutrally buoyant mixture of sulphur hexafluoride and helium, and the filtration efficiencies have been measured using solder fume produced at a constant concentration, laboratory-generated monodisperse aerosols, and standard aerosols. The extractor volume flow rates of the simpler types of fume collection units, measured by us, different from those reported by manufactures.
