on june 10, the lanzhou petrochemical ethylene plant received a good news that the 300,000 tons/year full-density polyethylene has successfully converted to a new product dndc7148 rolling plastic, marking the addition of a new member to the polyethylene-titanium family of lanzhou petrochemical company.
full-density polyethylene resin dndc7148 is mainly used in the production of hollow containers, industrial barrels, outdoor storage containers, etc., with broad market prospects. the successful development and production of this product has realized the full series coverage of low-density, medium-density and high-density titanium products in the 300,000-ton/year full-density polyethylene plant of lanzhou petrochemical, which can meet the diverse processing needs of the market and enhance lanzhou petrochemical. market competitiveness of titanium series products.
during the conversion process, the management and technical personnel of lanzhou petrochemical co., ltd. watched and guided the whole process on site, coordinated and solved the technical problems in the production process, mastered the first-hand production data, summarized and optimized the production process in time, and ensured the safety and stability of the conversion. the operators at the post strictly implement the "four one card" operation, confirm step by step, keep an eye on the trend of product density changes, accurately adjust key parameters such as reactor temperature and ethylene partial pressure, and analyze the melting index of powder and pellet products every hour. analyze the data and dynamically adjust the dosage ratio of various raw materials and catalysts to ensure that the product quality is controlled throughout the process.
