On February 21, the polypropylene plant of North China Petrochemical Corporation successfully carried out pilot production of high melt index fiber material, marking an important step forward for the company in the field of high-performance resin materials and laying a solid foundation for future large-scale production. The high melt index fiber material developed using this degradation-based technology features high fluidity, a narrow molecular weight distribution, and low odor. It can be widely used in various fields such as medical and sanitary non-woven fabrics, clothing fabrics, and carpet yarns, offering broad application prospects and strong market demand. North China Petrochemical attaches great importance to this new product development effort. Technical personnel and the team of technicians hold regular seminars to develop trial production plans in strict accordance with production control requirements, revise the indicators and parameters related to the trial production process, and establish detailed emergency response plans for production. Inspections were carried out on the key equipment components such as the cutting knife, template, and feed hydraulic system of the pelletizer; maintenance was performed on the wear-prone parts to ensure the smooth progress of the trial production process. During the trial production phase, technical staff worked closely with equipment experts from Dalian Petrochemical Company to overcome various challenges. They kept a close eye on key parameters such as the torque of the main motor, the temperature of the cylinder, the temperature of the heat transfer oil, and the temperature of the water used for granulation. They strictly followed the procedures for adding degradation agents, and adjusted the amount of these agents added accordingly based on the data obtained from melt index analysis. Through joint efforts, 500 tons of qualified products were successfully produced. The successful trial production of this product has tested the company’s technical capabilities in the field of polypropylene production, bringing positive impacts and facilitating advancements in areas such as product diversification, market expansion, and the extension of the industrial chain.
