This application provides a forming process database-driven adaptive optimization method for loading parameters, comprising: Step 1, constructing a forming process database for metallic materials; Step 2, searching the forming process database to obtain a loading scheme for the metallic material from an initial macro-micro state to a target macro-micro state; Step 3, continuously loading and forming the metallic material based on the loading scheme and obtaining real-time loading parameter combinations, and estimating the real-time macro-micro state of the metallic material; Step 4, determining whether the deviation between the expected macro-micro state and the real-time macro-micro state exceeds a set threshold. If the determination result is yes, proceed to Step 5; otherwise, return to Step 3; Step 5, re-searching to obtain a loading scheme for the metallic material from the macro-micro state at the moment the deviation exceeds the set threshold to the target macro-micro state, and then returning to Step 3. The method of this application can optimize the forming process under the high-density loading parameter-forming evolution data driving of metallic materials.

This invention relates to the field of olefin polymerization technology, and discloses a novel SiO2-supported nickel catalyst and its application in ethylene polymerization. The catalyst uses a nickel complex containing a pyridine imine structure as the active center, and forms a stable heterogeneous catalytic system through the interaction of anchoring groups with an activated SiO2 support. Compared with traditional homogeneous nickel catalysts, this SiO2-supported nickel catalyst exhibits higher catalytic activity and better thermal stability in ethylene homopolymerization and copolymerization reactions, and can maintain stable polymerization performance over a wide temperature range. At the same time, by designing the catalyst structure and controlling the loading method, the molecular weight, molecular weight distribution, and branching degree of the polymer can be effectively adjusted, thereby achieving controllable adjustment of the structure and properties of polyethylene.
