Description

Technical Field

[0001] This invention relates to a green manufacturing method and system for engineering plastics and synthetic resins, belonging to the field of green manufacturing technology. Background Technology

[0002] In the current context of promoting green development, engineering plastics, as a widely used product, have attracted much attention. Currently, the manufacturing of engineering plastics involves high energy consumption, high costs, and high carbon emissions, whether in raw material collection, transportation, or plastic manufacturing. This contradicts the concept of green development. For example, unreasonable raw material transportation routes can lead to excessive fuel consumption, significantly increasing fuel usage and thus carbon emissions. Furthermore, the inefficient polymerization of synthetic resins into engineering plastics also increases carbon emissions and heat energy consumption. At the same time, the economic impact must also be considered in green manufacturing, meaning that while reducing environmental pollution, economic losses must not be prevented.

[0003] Most existing green manufacturing processes are controlled by humans, which saves costs by reducing the funds consumed in raw material collection, transportation and plastic preparation, thereby reducing environmental consumption and pollution to some extent. However, in the context of existing big data and AI technologies, green manufacturing processes carried out through such manual methods are obviously less efficient.

[0093] It should be noted that both the polymerization reaction process and the processing reaction process are multiple reaction processes. For example, there are three polymerization reaction processes. These three reactions have different chemical reaction equations, reactants, and products. However, all three polymerization reaction processes can produce synthetic resins, and the types of synthetic resins produced can also be different (as long as the final engineering plastics produced are consistent, this is to meet the user's requirements for engineering plastics).

[0109] Where S1 represents the carbon emissions from polymerization, and s2 represents the weight of the resin synthesized during the polymerization reaction. S3 represents the carbon content in the synthetic resin, and S3 represents the weight of the non-synthetic resin during the polymerization reaction. S1 represents the carbon content in the non-synthetic resin, and S2 represents the weight of the reactants during the polymerization reaction. Indicates the carbon content of the reactants during the polymerization reaction;
