Maoming Petrochemical: Optimized quality of linear polyethylene products

Since the beginning of this year, the Maoming Petrochemical Chemical Division's full-density workshop has focused on the goal of “implementing quality responsibility, consolidating the quality foundation, and steadily improving the overall quality level”, and intensifying efforts to improve production optimization and product quality, and strictly control product production. The various details of the process promote the steady improvement of product quality. Recently, in the September product quality stability ranking issued by the headquarters, linear full-density polyethylene products ranked first in the Sinopec system.

At present, the competition in the polyethylene product market is fierce. In order to further improve the quality of the products, we will win by quality. They will start from the details, carefully control each parameter of the reaction and granulation system, and focus on monitoring the appearance and cleanliness of the pellets. According to the small change of the differential pressure parameter before and after the changer, it is judged whether the filter screen in the system needs to be replaced. At the same time, the control range of the melt index of the product is reduced, and the QC control mode of the APC control system is used, and the tracking is performed for 24 hours. The change of product quality, timely adjustment, to ensure that the control value of the product is close to the central value. Quality is life, every detail on the production line can not be neglected, each pellet is a promise. In recent years, DFDA produced by full-density devices -7042, PE-L M2720 and other resin products, good processing performance, high quality products, praised by downstream customers.
