Description

Technical Field

[0002] In the current environment of promoting green development, engineering plastics as a widely used product have attracted much attention. At present, in the manufacture of engineering plastics, whether it is the collection of raw materials, the transportation of raw materials or the manufacture of plastics, there are problems of energy consumption, high cost and high carbon emissions, which are contrary to the concept of green development. For example, unreasonable raw material transportation routes will lead to excessive fuel consumption, greatly increase the use of oil, and thus increase carbon emissions. Furthermore, the reaction process of inefficient synthetic resin polymerization into engineering plastics will also increase carbon emissions and heat energy consumption. At the same time, in the green manufacturing process, the economic impact also needs to be considered. That is to say, while ensuring the reduction of environmental pollution, it is also necessary to ensure that the economy does not regress.
