Muva nje, i-catalyst ye-polypropylene ye-metallocene eyenziwe ngokuzimela yi-Beijing Research Institute of Chemical Industry iqede ngempumelelo ukuhlolwa kokuqala kwesicelo sezimboni kuyunithi yenqubo ye-polypropylene yepayipi eliyindandatho ye-Zhongyuan Petrochemical, futhi yakhiqiza ama-resin e-polypropylene e-homopolymerized kanye ne-random copolymerized metallocene asebenza kahle kakhulu. I-China Sinopec yaba yinkampani yokuqala e-China ukuthuthukisa ubuchwepheshe be-polypropylene ye-metallocene ngempumelelo ngokuzimela.
I-polypropylene ye-Metallocene inezinzuzo zokuqukethwe okuncibilikayo okuphansi, ukucaca okuphezulu kanye nokucwebezela okuphezulu, futhi iyisiqondiso esibalulekile sokuguqulwa nokuthuthukiswa kwemboni ye-polypropylene kanye nentuthuko ephezulu. I-Beihua Institute yaqala ucwaningo kanye nokuthuthukiswa kwe-catalyst ye-metallocene polypropylene ngo-2012. Ngemva kokuhlolwa okuncane, ukuhlolwa kwemodeli kanye nokulungiswa kokuhlolwa kokuhlolwa kokuhlola, yaxazulula izinkinga zobuchwepheshe ezifana nokuklama isakhiwo se-catalyst, inqubo yokulungiselela kanye nokwenza ngcono umsebenzi we-catalytic, futhi yathuthukisa ngempumelelo i-catalyst ye-metallocene polypropylene. Ubuchwepheshe be-catalyst ye-propylene kanye nokukhiqizwa kwemikhiqizo ye-catalyst. Ekuhlolweni okuqhathanisayo ngaphansi kwezimo ezifanayo ze-polymerization, i-catalyst inomsebenzi ophezulu kune-catalyst engenisiwe, kanti umkhiqizo we-polypropylene olungiselelwe unesimo sezinhlayiya ezingcono futhi awunayo i-agglomeration.
Kusukela ngoNovemba kulo nyaka, i-catalyst iqede izivivinyo zezimboni ngokulandelana esitshalweni se-Hypol process polypropylene saseYangzi Petrochemical kanye nesitshalo se-ring pipe process polypropylene saseZhongyuan Petrochemical, futhi yathola imiphumela emihle yokuqinisekisa. Lokhu kuhlolwa kwezimboni eZhongyuan Petrochemical kungokokuqala eShayina ukukhiqiza i-polypropylene ye-metallocene engahleliwe emshinini we-polypropylene yepayipi lendandatho, okubeke isisekelo esiqinile sentuthuko ephezulu yemboni ye-polypropylene yeSinopec.
