Recently, Lanzhou Petrochemical Company's full-density polyethylene plant successfully completed the first stage of chromium-based catalyst polyethylene with a total of 43,000 tons of production tasks, with significant synergies.
This year, Lanzhou Petrochemical Company plans to produce two grades of 96,000 tons of chromium-based catalyst polyethylene products in two stages. In production, Lanzhou Petrochemical Company changed its equipment, extruder drive, PDS plugging and other difficult solutions and product melting. Body strength, density, mechanical properties and other indicators control points are compiled into a book, systematically combing the process control of chromium-based catalyst polyethylene production, index control, key operational steps, and accumulated valuable practical experience for the next stage of production.
Lanzhou Petrochemical is also working hard to improve product quality, organize product quality research, and further improve the performance optimization plan of chromium-based catalyst polyethylene products. At the same time, they have completely solved the problem based on the quality control analysis of the central control, strict process index control and fine operation. The problem of yellowing of large blow molding barrels in pellet processing improves the tensile yield strength and meets the market demand for high-strength film processing.
In view of the difficulty in safety management during high-load production of chromium, Lanzhou Petrochemical strictly enforces the regulations for safe operation management, strengthens the special management of the operation of key equipment such as extruders and feeders, and strictly implements 'listening, watching, asking, Check, look at the 'five-word inspection method, increase the implementation of production programs and process discipline, labor discipline assessment, laid a solid foundation for the successful completion of the first half of the production tasks.
