Abstract


Impact copolymer polypropylene plant Plastic Factory of Qilu Petrochemical Corporation product SP179 development research project summarized the the SP179 product development background , process and technology characteristics of Qilu polypropylene plant , especially from the angle of product structure analysis analysis explores the impact of the SP179 product quality the important factors such as the gas phase reactor gas phase composition, the ratio of hydrogen ene , ethylene content , xylene solubles , intrinsic viscosity , finalize the product development and production in the control indicators , and in accordance with a predetermined the indicators of the development process before the scheduled checking of the control parameters . By scanning electron microscopy SEM , transmission electron microscopy TEM , differential thermal analysis DSC , NMR NMR , gel permeation chromatography GPC analysis of the product structure , and well-known foreign car bumpers AW191 products compared processing properties of the product were investigated. The results indicate that the development and production of the product is fully able to achieve similar products imported the AW191 quality indicators to meet user needs . SP179 as domestic development and production of car bumpers products , has become the iconic products of of Qilu polypropylene device .
