A writing device assembly and a writing content identification method are provided. The assembly includes a writing apparatus including a pressure sensing unit, an optical identification unit and a processor, and a writing medium having code points printed thereon. The pressure sensing unit generates a pressure sensing signal when sensing that the writing apparatus contacts the writing medium. The optical identification unit captures a code point image of the code points in the writing medium when the pressure sensing unit generates the pressure sensing signal, analyze the code point image to obtain a code point value, and send the code point value to the processor. The processor identifies a code point type of the code point value, analyzes the code point value to determine a writing trace when the code point type is identified to be a coordinate code, and identifies the writing trace to obtain writing content.

The present invention discloses a regenerated HIPS/PPO alloy material based on chemical and physical co-modification, which is mainly composed of the following components in parts by mass: waste HIPS 60-70, PPO 30-40, HIPS-based macromolecular chain extender 2-8, elastomer toughening agent 2-10, oxazoline chain extender 0.2-1, and chain-extension catalyst 0.1-0.4. The alloy material uses chemical modification of in-situ chain extension and compatibilization of the macromolecular chain extender to restore a molecular chain structure, improve a phase interface and increase compatibility of the alloy. Through physical modification introduced by adding the elastomer toughening agent, a combined effect of chemical modification and physical modification is exploited, with target properties improved, a regenerated plastic alloy material with an excellent comprehensive property prepared, and the waste fully utilized to achieve energy saving and emission reduction. A method for preparing the above-described alloy material is also disclosed.
