Since the production of metallocene polyethylene began on March 5th, after optimized operation, as of March 15th, Yangzi Petrochemical Plastics Plant has produced more than 3,000 tons of metallocene polyethylene pipe material mPE P3806R in 10 days, successfully realizing the metallocene polyethylene pipe material product mPE P3806R.
Industrial mass production of polyethylene

As a replacement import project of Sinopec Group Corporation, Yangzi Petrochemical attaches great importance to the research and development of metallocene polyethylene products, and has carried out long-term follow-up and research and exploration
.
The development and production of metallocene polyethylene series products is a key part of Yangzi Petrochemical's plastic product structure adjustment and optimization work, and it is also the highlight of tackling difficulties and creating benefits
.
Since the metallocene catalyst is extremely sensitive to impurities, a little carelessness may lead to production failure.
Therefore, in this high-volume production, the polyethylene workshop carried out equipment cleaning and maintenance in advance to create conditions for the production of metallocene products
.
In order to ensure the activity of the metallocene catalyst and avoid the generation of crystal points, the polyethylene workshop starts from the regeneration of the refining system, the cleaning and debugging of the dry powder feeder, the jet cleaning of the circulating gas line, the cleaning of the inner wall of the reactor distribution plate, the replacement of the filter bag, and the degassing chamber.
Cleaning and inspection, workshop cadres and employees carry forward the spirit of nailing nails, strictly implement two rules and one card in the production process, carefully operate, pay close attention to various indicators of the product, and overcome the disturbance of feeding, the fluctuation of reaction temperature, and the mutual interference of hexene and hydrogen copolymerization in the production process After a series of difficulties, we finally successfully produced qualified metallocene polyethylene products
.
