Tempered glass is generally considered as a safety glass, when it breaks, it will split into small blunt particles, reducing the risk of injury to the human body. Laminated glass is composed of two or more layers of glass sandwiched by one or more layers of PVB (polyvinyl butyral) film, even if the glass breaks under impact or damage, laminated glass can still maintain a certain structural integrity, and the PVB layer can adhere the fragments together to prevent splashing injury.
[0003] Currently, the main problems and difficulties in sorting out scrap tempered and laminated glass include:
[0004] (1) High cost of manual sorting: Since tempered glass and laminated glass are usually mixed together, manual sorting is required, which not only is low in efficiency, but also is high in cost.
[0005] (2) Small difference in physical properties: The difference in physical properties between tempered glass and laminated glass is small, which makes it difficult to effectively separate them by traditional mechanical or automated methods.
[0006] (3) Safety risk: Tempered glass forms sharp small pieces after breaking, posing a safety risk to workers, and appropriate safety measures need to be taken.
[0007] (4) Difficulty in removing impurities: Tempered glass sales standards cannot have laminated glass, including PVB glue in laminated glass. If the PVB glue is embedded in the broken glass, it is very difficult to sort manually.
