The invention discloses a high-performance processing technology and equipment for polymer disentanglement through supercritical fluid micro-explosion. Supercritical fluid penetrates into molecular chain clusters to realize micro-explosion and disentanglement of single molecular chains while orienting the chain segments. Through kneading and exhausting simultaneously, the orientation effect formed by micro-explosion is maintained, secondary orientation is completed, and internal gas is discharged. Combined with lamination processing, the chain clusters in materials are fully oriented to obtain textured structural materials, and the final reinforced products are free of bubbles. The supporting equipment consists of drying system, impregnation system, micro-explosion system, exhaust extrusion system, temperature control system and other basic units. The proposed processing technology and equipment can continuously, efficiently and cost-effectively disentangle polymer chain clusters and primary particles via supercritical fluid micro-explosion. Mechanical exhausting ensures that micro-explosion oriented chain segments smoothly enter the subsequent orientation process. Combined with laminated extrusion technology, bubble-free materials with higher orientation degree and neatly arranged molecular chains are produced, which effectively optimize the comprehensive service performance of polymers.
