Triboelectric charging of polyethylene powders: Comparison of same-material and different-material contributions to the charge build-up
Original language description
The understanding of triboelectric charging of industrially important powders can help in avoiding or controlling the particle agglomeration and wall sheeting. We developed a new experimental approach to study both same-material particle-particle (P[sbnd]P) and different-material particle-wall (P[sbnd]W) charging of nascent polyethylene (PE) particles born by catalytic polymerization. We constructed a simple tribocharger consisting of a metal box divided inside into several compartments filled with the PE sample and attached to the vibration shaker. The particle charge distribution was characterized by a self-constructed electrostatic separator. This way, we investigated the charging dynamics of PE particles colliding with other PE particles as well as with metal walls of the box compartments. Both P[sbnd]P and P[sbnd]W charging were measured either separately, or in sequence, and in combination of simultaneous P[sbnd]P and P[sbnd]W. The different-material P[sbnd]W charging produced unipolarly charged particles and was much faster than the same-material P[sbnd]P charging leading to bipolar particle charge distribution. © 2020 Elsevier B.V.
