China Drying Network News As of today, Jingmen Petrochemical's large-scale polypropylene special escort unit—pressing and extruding machine running continuously for 112 days without trouble, once again broke the 91-day operating record, achieved two record-breaking results in one year, reached new heights and became a The same type of device and the same type of unit are listed first.
As a large-scale chemical special-protection unit, the polypropylene extrusion granulation unit has the characteristics of complex design and high degree of self-control. It has been known for many interlocks and is difficult to continuously operate. The industry average continuous trouble-free operation time is less than 50. day.
Jingmen Petrochemical's No. 1 polypropylene extrusion machine was running for 14 years and was in a period of “bottleneck†of equipment. From the beginning of the production cycle on March 21, the unit maintained a high load operation of nearly 14 tons per hour and produced 30,513.55 tons of qualified polypropylene, of which the high value-added product Z30S non-woven special material reached 6511 tons, not only improving Market competitiveness, and achieve maximum benefits.
Since the fourth quarter of last year, Jingmen Petrochemical's polypropylene production has been market-oriented, and its products have been sold at a fixed rate. Processing five kinds of grades within one month has become the norm. This has enabled the production of polypropylene devices to reach the ultimate level and stabilize the extrusion equipment. Operation put forward higher requirements.
The company strengthens the unit's special protection management and regulates the use of three chemical additives and extrusion additives. In particular, the production of high-thickness index products “has a good care†to avoid impact on the extrusion granulation unit during the conversion process. They also reconstructed the instrument control system and took the lead in increasing the production load and the pelletizer speed control interlock in the industry, which greatly improved the reliability of equipment operation.
In the current round of production cycle, Jingmen Petrochemical's extrusion granulating unit “has not lived up to expectationsâ€, operating at an average load of 13.97 tons per hour, setting a record for the same time, and entering the advanced ranks of the same type of installations and units of the same type in the entire system.
