I kēia mau lā, ua hoʻokō pono ka metallocene polypropylene catalyst e ka Beijing Research Institute of Chemical Industry i ka hoʻāʻo noiʻi ʻoihana mua i ka pūʻulu apo polypropylene kaʻina hana o Zhongyuan Petrochemical, a hana i ka homopolymerized a me ka copolymerized polypropylene resins metallocene me ka hana maikaʻi loa.Ua lilo ʻo China Sinopec i hui mua ma Kina i hoʻomohala kūʻokoʻa kūʻokoʻa i ka ʻenehana metallocene polypropylene.
Loaʻa i ka Metallocene polypropylene nā mea maikaʻi o ka haʻahaʻa haʻahaʻa haʻahaʻa, ke aniani kiʻekiʻe a me ka ʻālohilohi kiʻekiʻe, a he kuhikuhi koʻikoʻi no ka hoʻololi a me ka hoʻomaikaʻi ʻana i ka ʻoihana polypropylene a me ka hoʻomohala kiʻekiʻe.Ua hoʻomaka ʻo Beihua Institute i ka noiʻi a me ka hoʻomohala ʻana o ka metallocene polypropylene catalyst ma 2012. Ma hope o ka hoʻāʻo liʻiliʻi, ka hoʻāʻo ʻana a me ka hoʻomaʻamaʻa hoʻokele hoʻomaʻamaʻa hoʻomākaukau ʻana, ua hoʻoponopono ʻia nā pilikia ʻenehana e like me ka hoʻolālā ʻana i ka hoʻolālā catalyst, ke kaʻina hana hoʻomākaukau a me ka hana catalytic optimization, a ua hoʻomohala maikaʻi i ka metallocene polypropylene. mea hoʻopāpā.ʻenehana propylene catalyst a me ka hana ʻana i nā huahana catalyst.Ma ka loiloi hoʻohālikelike ma lalo o nā kūlana polymerization like, ʻoi aku ka nui o ka hana o ka catalyst ma mua o ka catalyst i lawe ʻia mai, a ʻoi aku ka maikaʻi o ka huahana polypropylene i hoʻomākaukau ʻia a ʻaʻohe agglomeration.
Mai Nowemapa i kēia makahiki, ua hoʻopau ka catalyst i nā hoʻokolohua ʻenehana i ka Hypol kaʻina polypropylene mea kanu o Yangzi Petrochemical a me ke apo paipu kaʻina polypropylene mea kanu o Zhongyuan Petrochemical, a loaʻa nā hopena hōʻoia maikaʻi.ʻO kēia hoʻokolohua ʻoihana ma Zhongyuan Petrochemical ʻo ia ka manawa mua ma Kina e hana i ka polypropylene copolymerized metallocene polypropylene ma luna o kahi mea hana polypropylene ring pipe, kahi i hoʻokumu i kahi kumu paʻa no ka hoʻomohala kiʻekiʻe o ka ʻoihana polypropylene a Sinopec.
