| Research Abstract |
To develop new electro-magnetic powder process, an experimental research work of plastic film or ceramic powder coating on various metal particles was successfully finished.
Experimental apparatus is a quartz-glass fluidized bed to fluidize plastic or ceramic powder. To produce high frequency electron-magnetic field in the bed, high frequency power is loaded to a coil around the out side of the bed.
When the electro-magnetic field is produced in the bed, the temperature of non-electro-conductive plastic or ceramic powder is not changed. However, the temperature of the electro-conductive metal particles fed into the bed from the top of the bed are immediacy increased during their passing through the coil part and they are cooled down at the bottom part of the bed. For the case of the ceramic powder, increasing the metal temperature higher than their melting point, the ceramic powder is coated on the surface of the metal particles. For the case of the plastic powder, increasing the temperature of the metal particles higher than the melting point of the plastics, the plastic film is coated around the metal particles. It is also found that the film tickness of the plastics can be controlled by changing operating conditions.
It is confirmed by this work that this new technology can be widely applied to utilize various wasted plastics.
