6 FAQs about [Separation of photovoltaic panel glass and silica gel]

Does solid-liquid ratio affect the separation time of PV modules?

While the increasing in solid-liquid ratio does not affect the separation of immersed PV modules. Meanwhile, results show that the separation time of PV modules is determined by the peeling time of the glass. Compared with toluene, pieces of Silicon wafer can keep their initial size due to the low swelling ability of DMPU.

Can shredded EOL PV panels be recycled?

Volume 72, pages 2615–2623, (2020) One of the technical challenges with the recovery of valuable materials from end-of-life (EOL) photovoltaic (PV) modules for recycling is the liberation and separation of the materials. We present a potential method to liberate and separate shredded EOL PV panels for the recovery of Si wafer particles.

How to separate glass from PV glass?

To effectively separate glass from the PV piece, the penetration of separation reagents into the glass-EVA gap is extremely important. Therefore, the wettability of the medium on glass is an important factor. The PV glass used in this experiment has one side with a rough surface and the other side with a smooth surface.

What is the difference between mechanical and thermal treatment of photovoltaic panels?

The mechanical methods include crushing, attrition, and vibration for glass separation and is the less polluting method compared to the other two [ 10, 11, 12 ]. Thermal treatment is mainly used to remove the polymeric fraction of the photovoltaic panel, i.e., EVA resin and backsheet materials [ 13, 14 ].

What are the separation methods for different layers in PV modules?

Separation methods for different layers in PV modules include physical methods, pyrolysis and chemical methods [ , , ]. Physical methods such as crushing, hammer crushing, triple crushing and high voltage pulse crushing are relatively environmentally friendly and simple to operate.

Can Egda be used as a separation reagent for waste PV modules?

Based on the above study, a new method for recycling waste PV modules using EGDA as a separation reagent was proposed. As shown in Fig. 10c, the aluminum frame and junction box are removed mechanically in advance, and then the backsheet is removed by physical methods like an edge milling machine used.
