4 FAQs about Photovoltaic panel grinding and peeling principle diagram

Can selective grinding remove resin from glass in silicon-based PV panels?

Selective grinding during the initial stage of grinding is effective for removing resin from glass in silicon-based PV panels. Many previous studies on the separation of glass from resin have investigated the applicability of chemical processes, but we achieved separation by brief physical processes.

Can a PV panel be used as a raw material?

The selectivity was high at a high rotation speed and during the initial stage of grinding. We found that 97% of the glass in a PV panel can be recovered with less than 1% C contamination for particles smaller than 5.6 mm by grinding at 2500 rpm for 5 min. The resulting glass particles are suitable for use as raw material for glass fiber.

How is selective grinding used to remove resin from glass particles?

Selective grinding was used to remove resin from glass particles as a secondary grinding process for the recycling of glass from silicon-based PV panels.

What is a silicon based PV panel?

Most silicon-based PV panels have a three-layer structure consisting of flat glass, a cell sealed with ethylene–vinyl acetate (EVA), and a back-sheet made of a multi-layer film comprising polyvinyl fluoride (PVF), polyethylene terephthalate (PET), polyethylene (PE), and other components.
