Scope

Scope: This document specifies the terms and definitions, crushing requirements, wet dismantling requirements, post-processing requirements, dismantling degree requirements, safety requirements, environmental protection requirements, and management requirements for the physical field-enhanced wet dismantling process of discarded photovoltaic laminates. This document is applicable to the wet dismantling of discarded crystalline silicon photovoltaic laminates encapsulated by ethylene-vinyl acetate copolymer (EVA) film. The wet dismantling of other types of discarded photovoltaic laminates can be carried out by referring to this document. Main technical content: This standard includes the following six chapters of technical content: - Chapter 4: Crushing requirements: This section specifies the crushing processing method and the size of the laminates after crushing for discarded photovoltaic laminates, and proposes requirements for crushing equipment and dust emission control during the crushing process. - Chapter 5: Wet dismantling requirements: This section specifies the processing method for wet dismantling of discarded photovoltaic laminates, and puts forward requirements for the wet dismantling system from the aspects of mass transfer and heat transfer, and requirements for wet dismantling equipment from the aspects of annual processing capacity, equipment volume, and processing time. - Chapter 6: Post-processing requirements: This section specifies the post-processing method for wet dismantling of discarded photovoltaic laminates, and stipulates that the post-processing system should be equipped with metering pumps, centrifugal devices, circulating solvent storage tanks, recirculation pumps, and recirculation pipelines, etc., and stipulates the specific requirements for the above devices. - Chapter 7: Dismantling degree requirements: This section gives the calculation method of the dismantling degree, stipulates the dismantling degree that should be achieved fo
