Zhongke Refinery successfully trial-produced bimodal polypropylene pipe material

On July 21, Zhongke Refinery's 200,000-ton/year polypropylene plant successfully trial-produced bimodal polypropylene pipes, which further enriched the company's polypropylene product structure
.
The product has the characteristics of high stiffness, impact resistance, high temperature resistance and precipitation stability, and is widely used in underground drainage systems, sewer pipes and other fields
.

This product has the lowest melt index since the plant was put into operation.
Regional technicians have carried out technical research in combination with the actual production of the plant, reviewed and summarized the previous production experience of new products, optimized the trial production plan, formulated emergency plans in advance for production risks, and organized teams to conduct training and deductions
.

During the conversion at night, technicians and internal operators pay close attention to the circulation state of the reactor, finely adjust the reaction temperature and hydrogen concentration, and ensure that the density and pressure difference of the ascending section remain stable
.
At the same time, pay close attention to the change of melt index, and adjust the key parameters of reaction and extrusion granulation unit in time to ensure product quality
.
External operators increase inspection efforts, pay attention to the appearance of pellets in a timely manner, and ensure safe production of the device and stable product quality
