Method for monitoring melt index of product on line based on preceding physical property correction term correction extruder model |
| abstract |
The invention discloses a method for monitoring a product melt index on line based on a precursor physical property correction term correction extruder model, which monitors the quality of a polyolefin product through parameters such as current of a screw extruder, pressure of an extrusion die head and the like, and uses a precursor correction term to replace a model corrected by the change of product structure parameters along with process conditions, thereby greatly improving the monitoring precision of the model when monitoring different brands. The invention can realize the on-line monitoring of the product quality in the normal production process of the olefin homopolymer and the olefin copolymer, is timely and reliable, can warn the large change of the product quality, provides effective monitoring basis for the safe and stable production of the polyolefin production granulation process, and improves the product quality and the industrial production economic benefit. |
