Extrusion granulation unit for the 450,000-ton/year full-density polyethylene plant in the second phase of Zhejiang Petrochemical’s 40 million tons/year integrated refining and chemical processing project
Thread Content
The extrusion granulation unit for the 450,000-ton/year full-density polyethylene plant in the second phase of Zhejiang Petrochemical’s 40 million tons/year integrated refining and chemical processing project is a set of large-scale equipment supplied by the Japanese supplier JSW. This complete set of equipment is the core equipment for the project. It features a complex production process, high degree of interdependence among its components, significant difficulties in design, manufacturing, and operation, as well as high costs. It is a large-scale integrated system that combines machinery, electricity, and instrumentation to a high degree.
It is said that the localization of PP/PE extrusion granulation units has made rapid progress in recent years; it remains to be seen whether they can keep up with the pace of the times.
It depends on the attitude of domestic users; it is said that the core components are still imported
It seems like you know some things; could you tell me more? For example, provide a brief overview of the localization status of melt pumps, pelletizers, mixers, reducers, high-pressure high-power motors, and so on
You can also start discussions on the forum; the mobile devices section is available for that
