Description

Technical Field

[0001] This utility model relates to the field of stirring device technology, and in particular to a polypropylene catalyst feeding and stirring device. Background Technology

[0002] In recent years, with the continuous development of my country's economy and the sustained improvement of consumption levels, the plastics processing industry has faced challenges from new demand trends such as "functionalization," "lightweighting," and "micro-molding." This is particularly true in the field of transparent polypropylene injection molded products, such as medical devices, food storage containers, and food storage boxes, where market demand is growing rapidly, driving the rapid development of polypropylene injection molding technology and the upgrading of production equipment. Polypropylene (PP), as an inexpensive and rigid general-purpose plastic, has seen its applications continuously expand. To meet the market's demand for high-quality, high-transparency polypropylene products, manufacturers are adopting advanced manufacturing processes and high-quality raw materials to improve product performance and appearance.

[0003] Polypropylene catalysts and other added catalysts typically contain a significant amount of impurities. Uneven distribution or excessive levels of these impurities can disrupt the equilibrium, leading to decreased transparency. Sulfides have a profound impact on the activity of the catalyst used in the polymerization reaction. They can chemically react with the active sites of the catalyst, deactivating them and severely disrupting the normal progress of the polymerization reaction. This results in problems such as yellowing of the product, decreased transparency, and substandard mechanical properties. Furthermore, some existing stirring devices are prone to uneven mixing between the polypropylene catalyst and other added catalysts during actual use, which can also affect the performance. Therefore, it is necessary to address these issues. Utility Model Content
