ʻO ka polypropylene kiʻekiʻe e pili ana i nā huahana polypropylene ma waho aʻe o nā mea maʻamau (ka kaha kiʻi, haʻahaʻa haʻahaʻa melt copolymerization, homopolymer injection molding, fiber, etc.), me ka ʻaʻole i kaupalena ʻia i nā mea maopopo, CPP, nā mea paipu, ʻekolu huahana kiʻekiʻe.

I kēia mau makahiki i hala iho nei, ua lilo ka polypropylene kiʻekiʻe i kahua kaua, ke hoʻomau nei ka hoʻonui ʻana i ka mana hana PP kiʻekiʻe, ka polypropylene foaming, metallocene polypropylene, ʻekolu polypropylene kiʻekiʻe, ultra-low ash polypropylene a me nā ʻano hou o ka māhele mākeke he haʻahaʻa, akā ʻo ka he ākea ka makemake, nui ka hiki ke hoʻomohala i ka mākeke;Ma ka makahiki 2021, hiki i ka 7,963,400 tons ka puka o ka polypropylene kiʻekiʻe, ʻo ka nui o ka lawe ʻana mai he 2,399,100 tons, a ʻo ka hilinaʻi lawe mai i 23.57%.Ke kū nei kekahi mau huahana i ke kūlana monopoly haole a ke hele nei i ke kaʻina hana o ka hoʻomaka ʻana mai ka ʻōpala.ʻO ka manawa o 2021-2025 ka pae hoʻomohala holomua o ka polypropylene kiʻekiʻe, a e lohi ka ulu ʻana ma 2025-2030.

I ka makahiki 2022-2030, 35.63 miliona tons / makahiki o ka hoʻokomo ʻana i ka polypropylene e hoʻolālā ʻia e hoʻokomo ʻia i loko o ka hana ʻoihana ma Kina, akā ʻo ka polypropylene kiʻekiʻe wale nō ka helu ma kahi o 30% o ka hoʻonui polypropylene hou, no laila ma kahi o 10,7 miliona. mau tona.Ma waho aʻe o ka ʻāpana o ke kaʻina hana PDH, no ka mea hiki i kāna kumu ethylene manuahi ke hana wale i ka polymer homogeneous, ʻaʻole ia e hoʻokaʻawale ʻia i nā pae o ka polypropylene kiʻekiʻe i ka manawa pōkole, a me kahi ʻāpana o ka mea hoʻomaʻemaʻe lanahu a me nā mea hana ʻē aʻe. no ka mea, ʻaʻole paʻa ke kaʻina hana hou, ʻaʻole oʻo ka ʻenehana a ʻo nā kumu ʻē aʻe e hoʻonui ai i ka hoʻomohala ʻana i ka ʻoihana hoʻomaʻemaʻe a me ka lanahu, no laila, ʻo nā mea maʻamau e like me ka uea e huki ana i ka copolymerization hoʻoheheʻe haʻahaʻa i pā i ka mākeke, ʻaʻole ia i helu ʻia he polypropylene kiʻekiʻe. no ka manawa;I ka wā e hiki mai ana, e hoʻonui aku ʻo Sinopec a me CNPC i ka mana ma muli o kā lākou moʻolelo waiwai a me ka hana paʻa.ʻO kā lākou hoʻolālā e kālele ana i ka noi mākeke kiʻekiʻe.I ka wā e hiki mai ana, e hoʻomau ka hoʻokūkū no ka polypropylene kiʻekiʻe i nā ʻaila ʻelua.

I ka ʻōlelo o ka noi, ʻo ka polypropylene kiʻekiʻe i kēia manawa i ka noi nui loa no ka hoʻololi ʻana i ka automotive.ʻO ka hoʻomohala wikiwiki ʻana o ka manaʻo māmā automotive a me nā kaʻa ikaika hou i hāʻawi i ka ikaika nui i ka mākeke hoʻololi automotive.ʻO ke kumu nui o ka ulu ulu ʻana ʻo ka medium-high fusion copolymerization.ʻO ka lua, ʻo ia ka hoʻoheheʻe ʻia ʻana o ka paia lahilahi.Ua hoʻohui ʻia ka ʻeke lawe lawe i loko o nā ʻano maʻamau.Ua ulu wikiwiki ka ʻoihana lawe waho ma lalo o ke kōkua o nā hanana olakino lehulehu.ʻOi aku ka nui o ka ulu ʻana ma mua o ka nui o ka ulu ʻana o ka noi polypropylene.Hoʻohana nui ʻia ka ʻoihana māmā a loaʻa ka manaʻo ākea.Hoʻohana nui ʻia ia i loko o nā ʻeke infusion lāʻau lapaʻau, nā lāʻau lapaʻau, ka pahu pahu pahu, nā huahana pēpē, a me nā mea ʻē aʻe ma waena o lākou, ʻo ka ʻike olakino olakino e pili ana i ka 40% o ka huina maopopo, ukali ʻia e ka pahu pahu.Ma muli o ke ʻano o ka ʻelemakule ma Kina a me ke kūlana o ka maʻi maʻi maʻamau, pono e hoʻomaikaʻi ke kila aniani, a ke hilinaʻi nui nei ka mākeke kūloko kūloko i ka lawe ʻana mai, no laila aia kahi wahi nui no ka hoʻomohala ʻana i ka mākeke kūloko i ka wā e hiki mai ana.ʻO ka mea hope loa, ʻo nā mea kiʻekiʻe kiʻekiʻe e like me ka binary a me ka ternary copolymerization CPP film a me ka paipu wai wela ua kaupalena ʻia i ka lako mākeke ma muli o kā lākou liʻiliʻi mākeke liʻiliʻi a me ka haʻahaʻa haʻahaʻa.Hiki i ka lako hale ke helu wale no ma kahi o 50% o ka māhele mākeke, a aia nō kahi wahi nui no ka pāʻani ma ka mākeke kūloko.I ka hōʻuluʻulu ʻana, ʻoi aku ka liʻiliʻi o ka ulu ʻana o ka hiki ʻana o ka polypropylene kiʻekiʻe kiʻekiʻe ma mua o ke kaomi mākeke holoʻokoʻa o ka polypropylene, a ʻo ka noi o ka mākeke he wahi nui no ka hoʻomohala ʻana, ʻo ka hoʻolālā e hiki mai ana o ka noiʻi polypropylene kiʻekiʻe a me ka hana hoʻomohala. pono.
