Since this year, aiming at the quality goal, Yangzi Petrochemical has continuously strengthened technology research, optimized production process control, and continuously promoted the quality management level of polyolefin products. The product pass rate has reached 100%, the first-class product rate has reached more than 99%, the excellent product rate has exceeded 96%, and the product quality stability Process Capability index (Cpk) assessment index has been better improved.

Yangzi Petrochemical set up a number of polyolefin product quality improvement teams, from the preparation of catalyst, production process control, auxiliary use, accurate measurement of instruments, process discipline and other aspects of the work, focusing on the bottleneck affecting product quality organization and technical research. Summarize and examine the shortcomings in quality management work in a timely manner, comprehensively sort out the quality management process, and clarify the responsibility of quality management.

Focus on the production of key products, make a timely production summary, and analyze the use of different batches of catalysts and the impact on product quality. In-depth analysis of the causes of product quality problems in this year, formulate measures for the existence of product quality problems, and put forward improvement measures for the key problems and weak links that affect and restrict the operation of the quality system, to ensure that each process, each step and each process in the production process can meet the standards and requirements, and continue to improve and improve the quality of the work.

In the first 8 months of this year, customized chlorinated polyethylene special material series products, high density wire drawing material and a number of fist products to achieve mass production, extra high and ultra-high molecular weight polyethylene special material output exceeded the plan 255%.

Yangzi Petrochemical further compacting quality management responsibility, promote the improvement of quality awareness of all staff, improve the quality control level of the whole process of production. Revised the "Rules for the quality Management of polyolefin grade switching", carried out the quality risk contracting mechanism, and improved the quality risk list.

The company schedules and tracks the quality fluctuations of upstream raw materials at any time, timely notifying the finished product production workshop to do a good job of monitoring and adjustment, the material laboratory increases the analysis frequency of raw material process samples, the personnel on duty carry out samples on time according to the analysis project and frequency, and the laboratory takes samples on time for analysis. Within 1 hour, the analysis results will be notified to the workshop or uploaded to the LIMS system. If the central control analysis project exceeds the indicator phenomenon, the staff on duty will adjust the operating parameters in time, and the duty monitor will organize the sampling and notify the analyst until it returns to normal.
