Zhongke Refinery successfully trial-produced new high-rigidity and high-crystalline polypropylene products

On April 4, Zhongke Refinery's 350,000-ton/year polypropylene plant successfully trial-produced PPH-MH20, a new high-rigidity and high-crystalline polypropylene product, filling the market gap of high-rigidity and high-crystalline polypropylene products in South China and will effectively alleviate the Import situation of this series of products in South China

Members of the Huang Jixing Labor Model Innovation Studio of Zhongke Refinery and Chemical Industry visited the market and found that there are many small household appliance companies in South China, and there is a huge demand for high-crystalline polypropylene, but most high-crystalline polypropylene products need to be imported

During the conversion process, the operator of the device carefully operated, using two sets of valves in parallel to control the amount of hydrogen added to the second reactor, with regular preventive vibrations; on-site repeated confirmation of the addition of electrons to ensure product isotacticity; use of a melt-finger instrument to check the particle size.

The plant management personnel cooperated closely with the team operators and operated meticulously, overcame the difficulties of large reaction fluctuations and the difficulty of stable discharge of the system, and successfully produced 1,000 tons of new products that meet the requirements of product quality indicators and meet customer needs
