A few days ago, the SINOPEC convened training for various companies under the “Synthetic Resin Stability Study” project. Among them, the HDHM plastic HDPE HHM5502LW produced by the high-density unit of the Maoming Petrochemicals Division was obtained with a large-scale improvement in quality. The recognition of the headquarters, at the meeting to experience the experience of various brother companies.
It is reported that in 2016, the Chemical Industry Department organized the North Chemical Research Institute to conduct a sampling comparison of hollow blown container polyethylene resins on the market. Among the 8 products at home and abroad, the HHM5502LW produced by Maoming Branch ranked behind, and the product quality was stable. Poor performance. Maoming Branch attached great importance to this and immediately led the Quality Management Department to set up a quality improvement research team to do everything possible to carry out the quality improvement 'fighting and fighting'. They organized production workshops, research institutes, supply, sales, quality inspections, etc. several times. The department discussed the research, analyzed the problems, combined the product status and market research conditions to determine the direction of quality improvement. By narrowing the control range of the melt index, it invested in the QC control mode of the APC control system to track changes in product quality in 24 hours. Make quality adjustments to ensure that the product's control value is similar to the center value.
Since the beginning of this year, HHM5502LW has achieved remarkable progress in product quality stability through the efforts of all parties. Recently, according to the sampling data of the "2017 Synthetic Resin Stability Study Report" of the Chemical Industry Division, the current HMM5502LW indicators of Maoming Branch are all better than In 2016, it has been significantly improved, and has been 'liked' by downstream customers.
