AI Technical Summary
The current process of blending recycled PVC with virgin PVC does not involve precise analysis of the rheological properties of the materials, resulting in a cumbersome and inefficient process for optimizing the blending ratio, and making it difficult to meet the production requirements for mechanical and thermal properties.
By obtaining the complex viscosity and loss tangent of recycled and new materials at a preset angular frequency, the viscosity difference factor and elasticity difference factor are determined, a mapping relationship library is constructed, and the blending ratio reference range and processing parameter adjustment values are output to achieve precise matching of the operating parameters of the main processing equipment.
The process of optimizing the blending ratio of recycled PVC materials has been simplified, improving the quality stability of finished products and recycling efficiency, and ensuring that the materials maintain a stable and controllable rheological state during melt blending.
