Recently, various high-end products such as random thin-wall injection molded polypropylene of Maoming Petrochemical have achieved large-scale mass production. Among them, PPR-M55-S random injection molding products are the international leader in key indicators, and their excellent performance indicators benefit from the company’s Constantly optimize the quality of new products.
PPR-M55-S is a high-flow, high-rigidity product resin that requires the addition of ethylene in high-concentration hydrogen. Its melt index is very high. The material is extremely difficult to control in extrusion control and has reached the design of the device extrusion press. limit.
In order to increase the market share of the product, the Maoming Petrochemical Organization Research Institute, the Technical Quality Division of the Chemical Division, and the backbone of the polypropylene plant have been vigorously carrying out technological innovations. They have undergone several special meetings and technical forums, and have adjusted the scheduling plan accordingly. Grade switching sequence, optimizing the operating parameters of each parameter, refining the optimal 'match' of hydrogen and ethylene at the same time adding the reaction, and continuously optimizing the production scheme. In the production of PPR-M55-S this year, the switching transition time is better than before. Less than 5 hours, the parameters have been significantly improved.
'The new PPR-M55-S product we produce is currently highly recognized in the market. The customer's overall feedback on the product's liquidity is good, the rigidity is excellent, the odor is low, and the molding is fast!' Polypropylene workshop director Li Rongbo said happily.
In order to improve the new product control indicators and achieve a large-scale production scheduling, Maoming Petrochemical, while optimizing various new product solutions, strictly controls the adjustment of process parameters, and increases the qualification rate and smoothness rate of the process indicators in the 'Learning to Do More' technology module. The number of process parameters alarms, product qualification rate, etc., gradually solidify the product production model, so that the new product production will become more extensive and mature.
This year, Maoming Petrochemical's T4401 material, automobile fuel tank material HXB4505M, and high-fluidity impact polypropylene K7726H have all achieved industrial mass production. The output of new resin products reached 69,200 tons. First, increase efficiency over 10 million yuan.
