On September 26, Maoming Petrochemical solved the problem in the No. 3 polypropylene plant, overcoming the difficulty of production control, the powder is easy to stick, the reactor is easy to agglomerate, the extruder is difficult to cut, and so on. The ternary amalgamated polypropylene product F4608 is used to complete the first trial production of the grade. It is reported that at present, there are few varieties of ternary copolymer products in China, and there is a serious shortage of raw materials, which is still monopolized by imported products. F4608 It has the advantages of high heat sealing strength, low heat sealing initiation temperature, wide heat sealing window and good retort resistance and impact performance. It is widely used in food, stationery, cosmetics, clothes, cigarettes and other high-quality packaging fields.
During the trial production, they conducted research and exploration on the process hydration reaction and the three-effect evaporation system operation process parameters and the central control quality indicators. Through accurate analysis and calculation, the control process parameters of the system were adjusted and controlled, which not only ensured the system water balance and sewage after the installation. COD qualified emission, and the ethylene glycol product refining tower runs at high load. They also keep track of product quality, timely adjust relevant indicators according to product quality, guide the team to do a smooth operation, and lay a solid foundation for further increasing the load of the device. The foundation has set a new high in production.
