The development technology to recycle waste compact disk treatment by arc-discharge

High concentration alkali has been used for waste disk recycling treatment for many years. This paper proposes a novel process to handle recycling with a high voltage high frequency arc-discharge. This process can replace the original recycling process, which smashes the disks up and then separates metal cladding material from the disks, and reduce secondary pollution. The proposed approach instantly changes the metal cladding material temperature of the disk surface. The different coefficients of expansion between plastics and metal cladding material can be used to strip the disk surfaces. The variation of stripped quantity and the influence of polycarbonate (PC) structures were investigated using various voltages, frequencies, and discharging times. In the field tests, both the treatment time of waste disks and the influence of recycling quantities were improved effectively.
