Muva nje, i-metallocene polypropylene catalyst eyakhiwe ngokuzimela yi-Beijing Research Institute of Chemical Industry iqede ngempumelelo ukuhlolwa kwesicelo sokuqala semboni kuyunithi yenqubo yepayipi eliyindandatho ye-polypropylene ye-Zhongyuan Petrochemical, futhi yakhiqiza izinhlaka ze-metallocene polypropylene eziyi-homopolymerized futhi ezingahleliwe ezisebenza kahle kakhulu.I-China Sinopec yaba inkampani yokuqala e-China ukuzimela ngempumelelo ukuthuthukisa ubuchwepheshe be-metallocene polypropylene.
I-Metallocene polypropylene inezinzuzo zokuqukethwe okuncibilikayo okuphansi, ukukhanya okuphezulu kanye nokucwebezela okuphezulu, futhi iyisiqondiso esibalulekile sokuguqulwa nokuthuthukiswa kwemboni ye-polypropylene kanye nentuthuko ephezulu.I-Beihua Institute yaqala ucwaningo nokuthuthukiswa kwe-catalyst ye-metallocene polypropylene ngo-2012. Ngemva kokuhlolwa okuncane, ukuhlolwa kwemodeli kanye nokulungiselela ukuhlolwa kokuhlolwa komshayeli, yaxazulula izinkinga zobuchwepheshe ezifana nokuklama kwesakhiwo se-catalyst, inqubo yokulungiselela kanye nokwenza ngcono umsebenzi we-catalytic, futhi yathuthukisa ngempumelelo i-metallocene polypropylene. i-catalyst.Ubuchwepheshe be-propylene catalyst kanye nokukhiqizwa kwemikhiqizo ye-catalyst.Ekuhloleni okuqhathanisayo ngaphansi kwezimo ezifanayo ze-polymerization, i-catalyst inomsebenzi ophezulu kune-catalyst engenisiwe, futhi umkhiqizo we-polypropylene olungisiwe unomumo wezinhlayiyana ongcono futhi awunakho i-agglomeration.
Kusukela ngoNovemba kulo nyaka, i-catalyst iqede ukuhlolwa kwezimboni ngokulandelana kwe-Hypol process polypropylene plant ye-Yangzi Petrochemical kanye ne-ring pipe process polypropylene plant ye-Zhongyuan Petrochemical, futhi yathola imiphumela emihle yokuqinisekisa.Lokhu kuhlolwa kwezimboni e-Zhongyuan Petrochemical ngokokuqala ngqa e-China ukukhiqiza okungahleliwe i-copolymerized metallocene polypropylene kudivayisi yepayipi eliyindandatho ye-polypropylene, eye yabeka isisekelo esiqinile sokuthuthukiswa okuphezulu kwemboni ye-polypropylene ye-Sinopec.
