ゴムシートによるインパクタ衝突板表面での粒子の跳ね返り抑制 Suppression of Particles Bounce-Off from Impaction Surfaces Using Rubber Sheet
Inertial impactors classify particles according to their aerodynamic diameter for the measurement of particle size distribution. When using inertial impactors, bounce-off, re-entrainment, and break up of particles upon the particle collision onto the impaction plate are inevitable problems. In this study, we investigated the effectiveness of rubber sheets to suppress particles bounce-off. We measured the adhesion efficiency of various rubbers by changing the particle diameter, impaction velocity and the temperature of rubber sheet. The adhesion efficiency of particles increases with impaction velocity when a rubber with a lower glass transition temperature was used as the impaction substrate. Furthermore, the particle bounce-off can be controlled for various kinds of rubber sheets by adjusting the temperature of rubber sheets.
