Description

Technical Field

[0001] The utility model relates to the technical field of PMI foam recovery, in particular to equipment for crushing and centrally processing PMI scraps. Background Art

[0002] PMI refers to polymethacrylimide foam plastic, which is a lightweight closed-cell rigid foam plastic. The foam plastic board made of this material has high strength, light weight and is widely used.

[0003] When processing PMI sheets, a large amount of scraps and unusable block-shaped residual materials are generated. When cleaning up these waste materials, the waste materials of similar sizes must first be sorted and bagged, and they take up a lot of space for stacking. The existing methods for processing PMI waste include first crushing the PMI waste. One way to use the crushed PMI waste is to mix it with glue and press it into composite sheets. Another way to treat it is to dissolve it in alkali solution and use it as a raw material for preparing phenolic resin.

[0004] Due to the high hardness of PMI itself, it is easy to appear overhead when crushing PMI materials, which affects the crushing efficiency.

[0005] Based on this, we now provide PMI scrap crushing and centralized processing equipment to eliminate the disadvantages of existing equipment. Utility Model Content
