Raman dispersion acquisition of signal manner and Raman dispersion acquisition of signal device, and identification manner and identification unit of plastic

摘要

Topic The transparent or translucent plastic being, it identifies that material accurately. SolutionsMounting suffering identification plastic P on belt 4a which was formed by the stainless steel steel board the conveyer it irradiates laser light L to suffering identification plastic P on 4 which it conveys and conveyer 4, obtaining the Raman scattered light R which, disperses from this suffering identification plastic P it has with the Raman dispersion identification machine 5 which identifies the material of suffering identification plastic P. Suffering identification plastic P being transparent or translucent, the laser light which transmitted suffering identification plastic P is reflected with the surface of belt, 4a because influence of the Raman effect by belt 4a decreases, can obtain the Raman dispersion signal where the suffering identification plastic P whose influence of this belt 4a is little is prominent, more accurate identification becomes possible.
