I nā makahiki i hala iho nei, me ka ulu mau ʻana o ka hiki ke hana i ka ʻoihana polypropylene kūloko, ua piʻi ka hana ʻana o ka polypropylene i kēlā me kēia makahiki. Ma muli o ka piʻi ʻana o ke koi no nā kaʻa, nā lako hale, ka uila, a me nā pallets, ke ulu wikiwiki nei ka hana ʻana o ka copolymer polypropylene kūpaʻa i ka hopena. ʻO ka hana i manaʻo ʻia o nā copolymers kūpaʻa i ka hopena i ka makahiki 2023 he 7.5355 miliona tons, he piʻi ʻana o 16.52% i hoʻohālikelike ʻia me ka makahiki i hala (6.467 miliona tons). Ma ke ʻano kikoʻī, ma ke ʻano o ka mahele ʻāpana, ʻoi aku ka nui o ka hana ʻana o nā copolymers haʻahaʻa melt, me ka hopena i manaʻo ʻia ma kahi o 4.17 miliona tons i ka makahiki 2023, e helu ana no 55% o ka nui o nā copolymers kūpaʻa i ka hopena. Ke hoʻomau nei ka hapa o ka hana ʻana o nā copolymers melting medium high a me nā copolymers kūpaʻa i ka hopena, e hiki ana i ka 1.25 a me 2.12 miliona tons i ka makahiki 2023, e helu ana no 17% a me 28% o ka huina.
Ma ke ʻano o ke kumukūʻai, i ka makahiki 2023, ua emi mua ke ʻano holoʻokoʻa o ka copolymer polypropylene kū i ka hopena a laila piʻi aʻe, a ukali ʻia e ka emi ʻana o ka nāwaliwali. ʻO ka ʻokoʻa o ke kumukūʻai ma waena o ka co polymerization a me ke kaha kiʻi uea i loko o ka makahiki ma waena o 100-650 yuan/ton. I ka hapaha ʻelua, ma muli o ka hoʻokuʻu mālie ʻana o ka hana ʻana mai nā hale hana hou, me ka wā ʻole o ke koi, ua nāwaliwali nā kauoha o nā ʻoihana huahana terminal a ʻaʻole lawa ka hilinaʻi kūʻai holoʻokoʻa, e hopena ana i ka emi ʻana o ka mākeke. Ma muli o ka piʻi nui ʻana o nā huahana homopolymer i lawe ʻia e ka hāmeʻa hou, ua ikaika ka hoʻokūkū kumukūʻai, a ke piʻi nei ka emi ʻana o ke kaha kiʻi uea maʻamau. Ma ke ʻano hoʻohālikelike, ua hōʻike ka copolymerization kū i ka hopena i ka pale ikaika i ka hāʻule ʻana, me ka ʻokoʻa o ke kumukūʻai ma waena o ka copolymerization a me ke kaha kiʻi uea e hoʻonui ana i kahi kiʻekiʻe o 650 yuan/ton. I ka hapaha ʻekolu, me ke kākoʻo kulekele mau a me ke kākoʻo kumukūʻai ikaika, ua hoʻokele nā mea maikaʻi he nui i ka hoʻihoʻi ʻana o nā kumukūʻai PP. I ka piʻi ʻana o ka lako o nā copolymers anti-collision, ua lohi iki ka piʻi ʻana o ke kumukūʻai o nā huahana copolymer, a ua hoʻi hou ka ʻokoʻa o ke kumukūʻai o ke kaha kiʻi copolymer i ka maʻamau.
ʻO ka nui o ka plastic i hoʻohana ʻia i nā kaʻa ʻo PP, a ukali ʻia e nā mea plastic ʻē aʻe e like me ABS a me PE. Wahi a ka lālā ʻoihana pili o ka Automobile Industry Association, ʻo ka hoʻohana ʻana i ka plastic no kēlā me kēia sedan hoʻokele waiwai ma Kina ma kahi o 50-60kg, hiki i nā kalaka kaumaha ke hiki i 80kg, a ʻo ka hoʻohana ʻana i ka plastic no kēlā me kēia sedan waena a me ke kiʻekiʻe ma Kina he 100-130kg. Ua lilo ka hoʻohana ʻana i nā kaʻa i mea nui ma hope o ka copolymer polypropylene kūpaʻa i ka hopena, a i nā makahiki ʻelua i hala iho nei, ua hoʻomau ka ulu ʻana o ka hana ʻana o nā kaʻa, ʻoiai me ka piʻi nui ʻana o nā kaʻa ikehu hou. Mai Ianuali a ʻOkakopa 2023, ua hiki ka hana ʻana a me ke kūʻai aku ʻana o nā kaʻa i 24.016 miliona a me 23.967 miliona, he piʻi ʻana o 8% a me 9.1% i kēlā me kēia makahiki. I ka wā e hiki mai ana, me ka hōʻiliʻili mau ʻana a me ka hōʻike ʻana o nā hopena kulekele o ka ulu ʻana o ka hoʻokele waiwai paʻa ma ka ʻāina, me ka hoʻomau ʻana o nā kākoʻo kūʻai kaʻa kūloko, nā hana hoʻolaha a me nā hana ʻē aʻe, manaʻo ʻia e hana maikaʻi ka ʻoihana kaʻa. Ua manaʻo ʻia e nui ka hoʻohana ʻana o nā copolymers kūpaʻa i ka hopena i ka ʻoihana kaʻa i ka wā e hiki mai ana.
