Mumakore achangopfuura, zvigadzirwa zvePE zvakaramba zvichienderera mberi munzira yekuwedzera-kumhanya. Kunyangwe hazvo PE inotengeswa kunze kwenyika ichiri kuverengera chimwe chikamu, nekuwedzera zvishoma nezvishoma kwesimba rekugadzira mudzimba, mwero wenzvimbo wePE wakaratidza maitiro ekuwedzera gore negore. Maererano nenhamba dzeJinlianchuang, kubva muna 2023, iyo yemba PE kugadzirwa kwesimba yasvika 30.91 miriyoni matani, ine vhoriyamu yekugadzira yakapoteredza 27.3 miriyoni matani; Zvinotarisirwa kuti kuchave kuchine 3.45 miriyoni matani emagetsi ekugadzira anoiswa mukushanda muna 2024, kunyanya akaiswa muhafu yechipiri yegore. Zvinotarisirwa kuti huwandu hwekugadzira hwePE huchaita 34.36 miriyoni matani uye kuburitsa kuchave kunosvika mamirioni makumi maviri nematatu emamiriyoni muna 29.
Kubva 2013 kusvika 2024, mabhizinesi ekugadzira polyethylene anonyanya kukamurwa kuita matanho matatu. Pakati pavo, kubva 2013 kusvika 2019, ndiyo inonyanya danho rekudyara remarasha kumabhizinesi eolefin, neavhareji yegore rekugadzira chiyero chekuwedzera kweanenge 950000 matani / gore; Nguva kubva 2020 kusvika 2023 ndiyo yepakati kugadzirwa nhanho yehombe-mwero yekunatsa uye makemikari indasitiri, panguva iyo avhareji yegore rekugadzira chiyero muChina yakawedzera zvakanyanya, inosvika 2.68 miriyoni matani pagore; Zvinotarisirwa kuti 3.45 miriyoni matani emagetsi ekugadzira acharamba achiiswa mukushanda muna 2024, nekukura kwe11.16% zvichienzaniswa ne2023.
Kutengeswa kwePE kwakaratidza kuderera kwemaitiro gore negore. Kubva 2020, nekuwedzera kwakadzama kwekunatsiridza kwakakura, huwandu hwekufambisa kwepasirese hwave hwakasimba nekuda kwezviitiko zvehutano hweveruzhinji, uye mitengo yekutakura zvinhu mugungwa yakawedzera zvakanyanya. Pasi pesimba revatyairi vemitengo, huwandu hwekunze hwe polyethylene yemumba hwakadzikira zvakanyanya kubva muna 2021. Kubva 2022 kusvika 2023, kugona kweChina kwekugadzira kuri kuramba kuchiwedzera, uye hwindo re arbitrage pakati pemisika yepamba nekunze rinoramba rakaoma kuvhura. Huwandu hwepasi rose hwePE yekunze hwadzikira kana ichienzaniswa ne2021, uye zvinotarisirwa kuti vhoriyamu yePE yekunze ichave 12.09 miriyoni matani muna 2024. Zvichienderana nemutengo uye yepasi rose-inoda kuyerera kwemaitiro, ramangwana kana yemukati PE yekupinda vhoriyamu ichaenderera mberi. kuderera.
Panyaya yezvinotengeswa kunze kwenyika, nekuda kwekugadzirwa kwakawanda kwekukwenenzvera kwakakura uye kwakareruka hydrocarbon zvikamu mumakore achangopfuura, kugona kwekugadzira uye kubuda kwakawedzera nekukurumidza. Zvikwata zvitsva zvine zvirongwa zvakawanda zvekugadzira, uye kudzvanywa kwekutengesa kwakawedzera mushure mekunge mayunitsi aiswa mukushanda. Kuwedzerwa kwemakwikwi emitengo yepasi pasi kwakonzera kukuvadzwa kwepurofiti pasi pemakwikwi emitengo yakaderera, uye mutsauko wenguva refu wakapidiguka wemutengo pakati pemisika yemukati neyekunze waita kuti zviome kune vatengi vekupedzisira kugaya chiyero chakadai chekuwedzerwa kwemari munguva pfupi. nguva. Mushure me2020, huwandu hwekutumira kunze kwePE kuenda kuChina hwakaratidza maitiro ekuwedzera gore negore.
Nekumanikidza kuri kuwedzera kwemakwikwi emumba gore negore, maitiro ekutsvaga kutumira kunze kwe polyethylene haigone kuchinjwa. Panyaya yezvinotengeswa kunze kwenyika, Middle East, United States nedzimwe nzvimbo dzichine nhamba huru yezviwanikwa zvisingadhuri, uye vanoramba vachiona China semusika mukuru wekutengesa kunze kwenyika. Nekuwedzera kwesimba rekugadzira mudzimba, kutsamira kwekunze kwepolyethylene kuchaderera kusvika 34% muna 2023. Zvisinei, inenge 60% yezvigadzirwa zvepamusoro zvePE zvichiri kuvimba nekutenga kunze kwenyika. Kunyangwe pachine tarisiro yekudzikira kwekutsamira kwekunze nekudyara kwesimba rekugadzira mudzimba, gaka rekuda kwezvigadzirwa zvemhando yepamusoro hazvigone kuzadzwa munguva pfupi.
Panyaya yezvinotengeswa kunze kwenyika, nekuwedzera zvishoma nezvishoma kwemakwikwi emumba uye kuendeswa kwemamwe maindasitiri ekugadzira edzimba akaderera kuenda kuSoutheast Asia, kudiwa kwekunze kwavewo nzira yekutsvaga kutengesa kumabhizinesi ekugadzira uye vamwe vatengesi mumakore achangopfuura. Mune ramangwana, zvichapawo mukana wekutengesa kunze, kuwedzera kutengesa kunze kwenyika kuSoutheast Asia, Africa, neSouth America. Padivi remukati menyika, kuenderera mberi kwekuita kweBelt uye Road uye kuvhurwa kweSino Russian kutengeserana zviteshi zvakagadzira mukana wekuwedzera kudiwa kwepolyethylene muNorthwest Central Asia uye Northeast Russian Far East matunhu.
