Since the beginning of this year, Maoming Petrochemical has been doing a good job in the development, production and optimization of resin products. It has actively promoted high-end and high-end resin products and strived to form a brand advantage. They optimized their product quality and promotional efforts, expanded product application scope, and improved key product indicators. Measures to achieve a significant increase in product structure and grade.
“In order to enhance market competitiveness and seize the commanding heights of benefits, we have taken great steps to innovate and optimize. In the past two years, there have been two scientific and technological breakthroughs in the success of resin products, which have won 4 patents. Three scientific and technological awards; three research results in cooperation with research institutes and universities were successfully applied industrially. 'The person in charge of Maoming Petrochemical said.
Key indicators are leading internationally. Recently, Maoming Petrochemical, Zhenhai Refining and Beijing Research Institute of Chemical Industry jointly undertook the key scientific and technological research project of the company's group - the development of a thin-walled injection-molded polypropylene resin resin project successfully passed the appraisal and won the unanimous praise from experts. It is considered that the product has excellent performance and the key indicators are leading internationally with significant benefits and advancements. It is reported that in the early stage of successful trial production of special materials for PPR-M55-S special-purpose materials for the development of thin-walled injection-molded polypropylene resin without warpage, the customer once Reflect the volatility of the brand, the product is unstable.
'2 # polypropylene plant operations, how do you order sample analysis? Clearly the last point of the melt index analysis in the normal range of ± 5g/10min or less ah!' In the beginning of a PPR-M55-S production, Quality inspection center inspectors call to ask the situation.
'This time our control standard is narrower than the normal range and must be within ±3g/10min. The current device's online melt index analysis detector has deviated from the central value of 2.7, according to the process control requirements, must add sample analysis. If exceeded The upper limit of control, the need to cut out processing. Trouble you!'s main operation Su Haibao explained one by one.
Polypropylene workshop carefully summarized the product quality control according to the customer's trial feedback, deeply studied, continuously improved the production plan, gradually refined the parameters of the control index, and tried every possible means to reduce the melt index range, and strived to improve the product quality in every production. 'One small step' .
In order to improve product quality, the Maoming Petrochemical project development team also re-adjusts the amount of hydrogen added during the grade switching process, steadily optimizes the timing and duration of ethylene addition under high-concentration hydrogen conditions, and narrows the range of process parameter settings. Through precision operations, they reduced the time required to switch grades, reduced the amount of transition materials, and improved product performance. Through technological transformation, they overcome difficult problems such as high melt index material extrusion molding and hard-to-drive vehicles, and finally produced products that satisfied customers. It is reported that since the PPR-M55-S product was successfully developed in April 2016, it has produced a total of 12,400 tons, with an increase of about 15 million yuan.
