The invention relates to the technical field of polymer material processing, in particular to a twin-screw configuration and processing technology for melt modification processing of polyvinyl alcohol (PVA) materials. According to the rheological characteristics of PVA materials, the invention defines the length proportion of each functional section in the screw and the model of screw elements adopted, so that the twin-screw configuration is fully matched with PVA materials, improving the melt mixing of PVA and effectively enhancing the plasticizing effect during PVA modification processing, thereby endowing modified PVA materials with better mechanical properties. Compared with the traditional research idea of modifying the formula of PVA materials, the invention provides a novel, universal and environmentally friendly solution, which plays a positive role in the improvement and in-depth development of twin-screw melt plasticizing modification technology for PVA materials.
