Loaʻa i ka Polyethylene nā ʻano huahana like ʻole e pili ana i nā ʻano polymerization, nā pae kaumaha molecular, a me ke degere o ka lālā.ʻO nā ʻano maʻamau ka polyethylene kiʻekiʻe (HDPE), polyethylene haʻahaʻa haʻahaʻa (LDPE), a me ka polyethylene haʻahaʻa haʻahaʻa laina (LLDPE).
ʻO ka polyethylene he mea ʻala ʻole, ʻaʻohe mea ʻawaʻawa, manaʻo e like me ka wax, maikaʻi loa ke kūpaʻa haʻahaʻa haʻahaʻa, kūpaʻa kemika maikaʻi, a hiki ke kū i ka ʻino o ka hapa nui o nā waikawa a me nā alkalis.Hiki ke hoʻohana ʻia ka polyethylene me ka hoʻohana ʻana i ka injection molding, extrusion molding, blow molding, a me nā ʻano hana ʻē aʻe e hana ai i nā huahana e like me nā kiʻiʻoniʻoni, paipu, uea a me nā kaula, nā pahu hollow, nā paʻi paʻi a me nā nakinaki, nā kaula, nā ʻupena iʻa, a me nā fiber i ulana ʻia.
Manaʻo ʻia ka emi ʻana o ka hoʻokele honua.E kū'ē i ke kumu o ka hoʻonui kiʻekiʻe, nāwaliwali ka hoʻohana a hoʻemiʻia ka noi.Eia kekahi, ke hoʻomau nei ka Federal Reserve i ka hoʻonui ʻana i ka uku ukupanee, ua hoʻopaʻa ʻia ke kulekele kālā, a ua paʻa nā kumukūʻai kūʻai.Eia kekahi, ke hoʻomau nei ka hakakā ʻo Russia-Ukraine a ʻaʻole maopopo ka manaʻo.He ikaika ke kumukūʻai o ka aila ʻaila, a ke kiʻekiʻe nei ke kumukūʻai o nā huahana PE.I kēia mau makahiki i hala iho nei, aia nā huahana PE i ka manawa o ka hoʻomau a me ka wikiwiki o ka hoʻonui ʻana i ka mana hana, a ua lohi nā ʻoihana huahana hope i ka hahai ʻana i nā kauoha.ʻO ka kū'ē kū'ē i ka hoʻolakoʻana ua lilo i hoʻokahi o nā pilikia nui i ka hoʻomohalaʻana i kaʻoihana PE i kēia manawa.
ʻIke a me ka wānana o ka hoʻolako ʻana a me ka koi ʻana o ka honua polyethylene
Ke hoʻomau nei ka ulu ʻana o ka polyethylene o ka honua.I ka makahiki 2022, ua ʻoi aku ka nui o ka hana polyethylene o ka honua ma mua o 140 miliona tons i kēlā me kēia makahiki, kahi hoʻonui makahiki-ma-makahiki o 6.1%, me ka piʻi ʻana o ka makahiki-ma-makahiki o 2.1% i ka hana.ʻO ka awelika o ka hana ʻana o ka ʻāpana he 83.1%, he emi o 3.6 pakeneka i hoʻohālikelike ʻia i ka makahiki i hala.
ʻO ka ʻĀkau Hikina o Asia ka hapa nui loa o ka mana hana polyethylene honua, ʻo ia ka 30.6% o ka nui o ka nui o ka polyethylene i ka makahiki 2022, a ukali ʻia e ʻAmelika ʻĀkau a me ka Hikina Waena, ʻo 22.2% a me 16.4% kēlā me kēia.
Ma kahi o 47% o ka mana hana polyethylene o ka honua i hoʻopaʻa ʻia i nā ʻoihana hana ʻumi kiʻekiʻe me ka mana hana.Ma 2022, aia ma kahi o 200 mau ʻoihana hana polyethylene nui ma ka honua.ʻO ExxonMobil ka ʻoihana hana polyethylene nui loa o ka honua, e helu ana ma kahi o 8.0% o ka nui o ka mana hana o ka honua.Aia ʻo Dow a me Sinopec i ka lua a me ke kolu.
I ka makahiki 2021, he 85.75 biliona kālā ʻAmelika Hui Pū ʻIa ka nui o ka nui o nā kālepa o ka honua, he 40.8% ka nui o ka makahiki ma ka makahiki, a ʻo ka nui o ke kālepa he 57.77 miliona tons, he 7.3% ka emi ʻana o ka makahiki ma ka makahiki.Mai kahi hiʻohiʻona kumu kūʻai, ʻo ke kumukūʻai kūʻai maʻamau o ka polyethylene i ka honua he 1484.4 US kālā no ke tona, he piʻi makahiki i ka makahiki he 51.9%.
ʻO Kina, ʻAmelika Hui Pū ʻIa, a me Pelekiuma nā mea lawe nui mai ka honua i ka polyethylene, ʻo ia ka 34.6% o ka nui o nā mea i lawe ʻia mai ka honua;ʻO ʻAmelika Hui Pū ʻIa, Saudi Arabia, a me Pelekiuma nā ʻāina nui e hoʻopuka ana i ka polyethylene ma ka honua, ʻo ia ka 32.7% o ka nui o nā hoʻoiho honua.
ʻO ka mana hana polyethylene o ka honua e mālama i ka ulu wikiwiki.I nā makahiki ʻelua e hiki mai ana, e hoʻonui ka honua ma mua o 12 miliona tons o ka polyethylene production capacity i kēlā me kēia makahiki, a ʻo kēia mau papahana ka hapa nui o nā papahana i hana ʻia me nā mea kanu ethylene upstream.Manaʻo ia mai 2020 a 2024, ʻo ka awelika o ka ulu ʻana o ka makahiki o ka polyethylene he 5.2%.
ʻO ke kūlana o kēia manawa a me ka wānana o ka hoʻolako ʻana a me ke koi ʻana o ka polyethylene ma Kina
Ua hoʻonui ʻia ka mana hana polyethylene a Kina i ka manawa like.I ka makahiki 2022, ua hoʻonui ʻia ka mana hana polyethylene o Kina e 11.2% makahiki-ma-makahiki a ua hoʻonui ʻia ka hana e 6.0% makahiki-ma-makahiki.Ma ka hopena o 2022, aia ma kahi o 50 mau ʻoihana hana polyethylene ma Kina, a ʻo ka mana hana hou ma 2022 ka nui o nā hui e like me Sinopec Zhenhai Refinery, Lianyungang Petrochemical, a me Zhejiang Petrochemical.
Ka Papa Hoʻohālikelike o ka Polyethylene Production ma Kina mai 2021 a 2023

ʻO ka piʻi ʻana o ka hoʻohana ʻana i ka polyethylene i kaupalena ʻia, a ʻo ka nui o ka pono ponoʻī e mālama i ka ulu.I ka makahiki 2022, ua hoʻonui ʻia ka hoʻohana ʻana o ka polyethylene ma Kina e 0.1% i ka makahiki, a ua hoʻonui ʻia ka nui o ka pono ponoʻī e 3.7 pakeneka i hoʻohālikelike ʻia i ka makahiki i hala.
Ua emi ka nui o ka polyethylene i Kina i kēlā me kēia makahiki, ʻoiai ua hoʻonui ʻia ka nui o ka lawe ʻana i kēlā me kēia makahiki.I ka makahiki 2022, ua emi iho ka nui o ka polyethylene o Kina e 7.7% o ka makahiki;Ua hoʻonui ʻia ka nui o ka lawe ʻana aku e 41.5%.Ke noho nei ʻo Kina i mea lawe mai i ka polyethylene.ʻO ke kālepa hoʻokomo polyethylene o Kina e hilinaʻi nui ana i ke kālepa maʻamau, ʻo ia ka 82.2% o ka nui o ka lawe ʻana mai;ʻO ka mea aʻe ke kālepa hoʻoili lawe ʻana, helu no 9.3%.No nā ʻāina a i ʻole nā ​​ʻāpana e like me Saudi Arabia, Iran, a me United Arab Emirates, e helu ana ma kahi o 49.9% o ka nui o nā mea lawe mai.
Hoʻohana nui ʻia ka polyethylene ma Kina, me ka helu kiʻiʻoniʻoni no ka hapalua o ka huina.I ka makahiki 2022, ʻo ke kiʻi ʻoniʻoni ʻoniʻoni ʻoi aku ka nui o ka papa noi haʻahaʻa o ka polyethylene ma Kina, a ukali ʻia e ka hoʻoheheʻe ʻia ʻana, nā kiʻi paipu, hollow a me nā māla ʻē aʻe.
Aia ka polyethylene o Kina i kahi pae o ka ulu wikiwiki.Wahi a nā helu helu ʻole, hoʻolālā ʻo Kina e hoʻohui i 15 mau pūʻulu o nā mea kanu polyethylene ma mua o 2024, me ka mana hana hou o 8 miliona mau tons i kēlā me kēia makahiki.
2023 PE Domestic Mea Hou Hana Papa Hana

Ma Mei 2023, ua hōʻea ka nui o ka hana o nā mea kanu PE home i 30.61 miliona tons.Ma nā ʻōlelo o ka hoʻonui ʻia ʻana o PE ma 2023, manaʻo ʻia ʻo 3.75 miliona tons i kēlā me kēia makahiki.I kēia manawa, ua hoʻokomo ʻia ʻo Guangdong Petrochemical, Hainan Refining and Chemical, a me Shandong Jinhai Chemical, me ka nui o ka mana hana o 2.2 miliona mau tona.Loaʻa iā ia kahi hāmeʻa piha piha o 1.1 miliona tons a me kahi hāmeʻa HDPE o 1.1 miliona tons, ʻoiai ʻaʻole i hoʻokomo ʻia ka mea hana LDPE i ka makahiki.Ma ka hapa lua o ka makahiki e hiki mai ana, aia nō he 1.55 miliona tons/makahiki o nā hoʻolālā hana hana hou, e pili ana i 1.25 miliona tons o nā lako HDPE a me 300000 tons o nā lako LLDPE.Manaʻo ʻia e hiki i ka nui o ka hana ʻana o Kina i 32.16 miliona tons e 2023.
I kēia manawa, aia kahi kūʻē koʻikoʻi ma waena o ka hāʻawi ʻana a me ka koi o PE ma Kina, me ka mana o ka hana ʻana o nā ʻāpana hana hou i ka pae hope.Eia naʻe, ke kū nei ka ʻoihana huahana i lalo i kahi paʻa o nā kumukūʻai maka, nā kauoha huahana haʻahaʻa, a me ka paʻakikī i ka hoʻonui ʻana i nā kumukūʻai ma ka hopena kūʻai;ʻO ka emi ʻana o ka loaʻa kālā a me nā kumukūʻai hana kiʻekiʻe ua alakaʻi i ke kahe kālā paʻa no nā ʻoihana, a i nā makahiki i hala iho nei, ma lalo o ke ʻano o ka piʻi nui ʻana, ua hoʻonui nā kulekele hoʻopaʻa kālā o nā ʻāina ʻē i ka hopena o ka hoʻokele waiwai, a me nā koi nāwaliwali i alakaʻi i kahi hōʻemi. i nā kauoha kālepa haole no nā huahana.ʻO nā ʻoihana huahana lalo, e like me nā huahana PE, aia i kahi manawa o ka ʻeha ʻoihana ma muli o ka hāʻawi ʻana a me ke koi ʻole.Ma kekahi ʻaoʻao, pono lākou e hoʻolohe i ka noi kuʻuna, ʻoiai e hoʻomohala ana i nā koi hou a loaʻa i nā kuhikuhi hoʻoiho
Mai ka mahele mahele o ka hoʻohana ʻana i ka PE ma lalo o Kina, ʻo ka hapa nui o ka hoʻohana ʻana he kiʻiʻoniʻoni, a ukali ʻia e nā ʻāpana huahana nui e like me ka hoʻoheheʻe ʻana, paipu, hollow, kaha kiʻi uea, kelepona, metallocene, uhi, etc. No ka ʻoihana huahana kiʻiʻoniʻoni, ʻO ke kumu nui he kiʻiʻoniʻoni mahiʻai, kiʻiʻoniʻoni ʻenehana, a me nā kiʻiʻoniʻoni hōʻailona huahana.Eia nō naʻe, i nā makahiki i hala iho nei, ua hoʻololi lohi ʻia ka noi no nā huahana kiʻiʻoniʻoni plastic disposable e ka kaulana o nā plastic degradable ma muli o ka palena o nā lula plastic.Eia kekahi, ʻo ka ʻoihana kiʻi ʻoniʻoni pū kekahi i ka manawa o ka hoʻoponopono ʻana i ka hoʻoponopono, a ʻo ka pilikia o ka overcapacity i nā huahana haʻahaʻa ke koʻikoʻi.
ʻO ka hoʻoheheʻe ʻana, ka paipu, ka hollow a me nā ʻoihana ʻē aʻe i pili pono i nā pono o ka ʻoihana a me ke ola kīwila i kēlā me kēia lā.I nā makahiki i hala iho nei, ma muli o nā kumu e like me ka manaʻo maikaʻi ʻole o ka poʻe kūʻai mai ka poʻe kamaʻāina, ua kū ka ulu ʻana o ka ʻoihana huahana i kekahi mau pilikia ulu, a ʻo ka hahai ʻana i nā kauoha hoʻokuʻu aku i alakaʻi i ka hiki ke emi i ka ulu ʻana i ka wā pōkole.
He aha nā wahi ulu o ka noi home PE i ka wā e hiki mai ana
ʻO ka ʻoiaʻiʻo, ma ka 20th National Congress i ka hopena o 2022, ua manaʻo ʻia nā ʻano hana like ʻole e hoʻoulu i ka noi kūloko, me ka pahuhopu e wehe i ke kaila kūloko ma Kina.Eia kekahi, ua ʻōlelo ʻia ʻo ka hoʻonui ʻana i ka helu urbanization a me ka nui o ka hana ʻana e lawe mai i ka hoʻoulu ʻana i ka noi i nā huahana PE mai ka manaʻo o ka hoʻolaha ʻana i loko.Eia kekahi, ʻo ka hoʻomaha piha ʻana o ka mana, ka hoʻihoʻi ʻana i ka hoʻokele waiwai, a me ka piʻi ʻana o ka noi no ka hoʻokele kūloko e hāʻawi pū i nā hōʻoia kulekele no ka hoʻihoʻi hou ʻana o ka noi home.
ʻO ka hoʻomaikaʻi ʻana i nā mea kūʻai aku ua hoʻāla i ka koi e kū mai ana, me nā koi kiʻekiʻe no nā plastics i nā kula e like me nā kaʻa, nā hale akamai, nā uila, a me nā kaʻa kaʻa.ʻO nā mea kiʻekiʻe kiʻekiʻe, hana kiʻekiʻe, a me nā mea pili i ke kaiapuni i lilo i mea makemake.ʻO ka nui o nā wahi ulu no ka noi e hiki mai ana ma nā wahi ʻehā, me ka ulu ʻana o ka ʻeke i ka ʻoihana hoʻopuka express, nā kiʻi ʻoniʻoni i alakaʻi ʻia e e-commerce, a me ka ulu ʻana o nā kaʻa ikehu hou, nā ʻāpana, a me nā koi olakino.Aia nō nā wahi ulu ulu no ka koi PE.
Ma keʻano o ka noi o waho, he nui nā mea i maopopo ʻole, e like me China US pili, Federal Reserve policy, Russia Ukraine kaua, geopolitical policy kumu, etc. huahana.Ma ke kahua o nā huahana kiʻekiʻe, nui nā loea a me nā ʻenehana i paʻa paʻa i nā lima o nā ʻoihana ʻē aʻe, a ʻoi aku ka koʻikoʻi o ka blockade ʻenehana o nā huahana kiʻekiʻe, no laila, ʻo ia hoʻi kahi wahi holomua no ka huahana o Kina e hiki mai ana. nā hoʻokuʻu aku, kahi e noho pū ai nā manawa a me nā pilikia.Ke kū nei nā ʻoihana kūloko i ka ʻenehana a me ka hoʻomohala ʻana.
