[0002] With the continuous development of technology, waste or damaged engineering plastic products can be recycled. Through sorting, cleaning, crushing and drying, the crushed materials are mixed with various repairing auxiliaries according to the formula, then the mixture is fed into a twin-screw extruder. Under the conveying, shearing, kneading and heating of the screws, the materials are melted, the auxiliaries are uniformly dispersed, and some in-situ chemical reactions (such as grafting and chain extension) may occur at the same time to repair the broken molecular chains.
