Polyethylene ine marudzi akasiyana echigadzirwa akavakirwa panzira dzepolymerization, mazinga ehuremu hwemamorekuru, uye dhigirii rebazi.Mhando dzakajairika dzinosanganisira yakakwirira-density polyethylene (HDPE), yakaderera-density polyethylene (LDPE), uye mutsara yakaderera-density polyethylene (LLDPE).
Polyethylene haina hwema, haina muchetura, inonzwa kunge wakisi, ine yakanakisa kudzikira tembiricha kuramba, kugadzikana kwakanaka kwemakemikari, uye inokwanisa kumira nekukukurwa kwemaasidhi mazhinji nemaalkali.Polyethylene inogona kugadzirwa uchishandisa jekiseni molding, extrusion molding, blowing molding, nedzimwe nzira dzekugadzira zvigadzirwa zvakaita semafirimu, pombi, waya netambo, midziyo isina maburi, matepi ekurongedza nematayi, tambo, mambure ehove, uye shinda dzakarukwa.
Hupfumi hwenyika yose huri kutarisirwa kudzikira.Kutarisana nemamiriro ekuwedzera kwepamusoro, kushandiswa hakuna simba uye kudiwa kunoderedzwa.Pamusoro pezvo, iyo Federal Reserve inoenderera mberi nekukwidza mitengo yemubereko, mutemo wemari wakasimbiswa, uye mitengo yezvinhu iri pasi pekumanikidzwa.Mukuwedzera, mhirizhonga yeRussia-Ukraine inoenderera mberi uye tarisiro haisati yanyatsojeka.Mutengo wemafuta asina kuchena wakasimba, uye mutengo wezvigadzirwa zvePE uchiri wakakwira.Mumakore achangopfuura, zvigadzirwa zvePE zvave munguva yekuenderera uye nekukurumidza kuwedzera kwehuwandu hwekugadzira, uye kudzika kwekupedzisira kwechigadzirwa mabhizinesi akanonoka kutevera pamaodha.Iyo yekupokana-yekuda kupokana kwave rimwe rematambudziko makuru mukusimudzira indasitiri yePE panguva ino.
Kuongorora uye Kufanotaura kweWorld Polyethylene Supply uye Demand
Nyika yekugadzira polyethylene inoramba ichikura.Muna 2022, kugadzirwa kwepolyethylene yepasirese kwakapfuura matani emamiriyoni e140 pagore, kuwedzera kwegore negore kwe6.1%, nekuwedzera kwegore negore kwe2.1% mukugadzirwa.Avhareji yehuwandu hwekushanda kwechikwata chaive 83.1%, kuderera kwe3,6 percentage points kana zvichienzaniswa negore rapfuura.
Kumaodzanyemba kwakadziva kumabvazuva kweAsia ndiko kune chikamu chikuru chepasi rose chekugadzira polyethylene, inoverengera 30.6% yehuwandu hwekugadzira polyethylene muna 2022, ichiteverwa neNorth America neMiddle East, inoverengera 22.2% uye 16.4% zvakateerana.
Inosvika makumi mana nenomwe muzana epasi rose rekugadzira polyethylene inonangana mumabhizinesi gumi epamusoro ekugadzira ane huwandu hwekugadzira.Muna 2022, pakanga paine mabhizinesi anoda kusvika mazana maviri ekugadzira polyethylene munyika.ExxonMobil ndiro bhizinesi hombe repasi rose rekugadzira polyethylene, rinoverengera ingangoita 8.0% yehuwandu hwepasi rose hwekugadzira.Dow neSinopec vari pachinzvimbo chechipiri nechechitatu zvakateerana.
Muna 2021, huwandu hwekutengeserana kwepasi rose hwepolyethylene hwaive 85.75 bhiriyoni US madhora, gore-pa-gore kuwedzera kwe40.8%, uye huwandu hwekutengesa huwandu hwaive 57.77 miriyoni matani, gore-pa-gore kuderera kwe7,3%.Kubva pamaonero emutengo, muvhareji wekutengesa kunze kwepolyethylene munyika ndeye 1484.4 US madhora patani, gore negore kuwedzera kwe51.9%.
China, United States, neBelgium ndidzo dzinotenga zvikuru pasi rose polyethylene, inotora chikamu che34,6% chezvose zvinotengwa kunze kwenyika;United States, Saudi Arabia, neBelgium ndidzo nyika huru dzinotumira kunze kwepolyethylene munyika, inoverengera 32.7% yezvese zvinotengeswa kunze kwenyika.
Nyika yekugadzira polyethylene inokwanisa kuchengetedza kukura nekukurumidza.Mumakore maviri anotevera, nyika ichawedzera anopfuura mamirioni gumi nemaviri ematani ekugadzirwa kwepolyethylene pagore, uye mapurojekiti aya anonyanya kubatanidzwa mapurojekiti anogadzirwa pamwe chete neakakwira ethylene zvidyarwa.Zvinotarisirwa kuti kubva muna 2020 kusvika 2024, avhareji yegore yekukura kwe polyethylene ichave 5.2%.
Ikozvino Mamiriro uye Kufanotaura kwePolyethylene Supply uye Kudiwa muChina
China's polyethylene kugadzira uye kubuda kwakawedzera panguva imwe chete.Muna 2022, huwandu hwekugadzira polyethylene hweChina hwakawedzera ne11.2% gore negore uye kugadzirwa kwakawedzera ne6.0% gore negore.Kubva pakupera kwa2022, kune angangoita makumi mashanu emabhizimusi ekugadzira polyethylene muChina, uye hutsva hwekugadzira muna 2022 hunosanganisira zvikamu zvakaita seSinopec Zhenhai Refinery, Lianyungang Petrochemical, uye Zhejiang Petrochemical.
Kuenzanisa Chati yePolyethylene Kugadzirwa muChina kubva 2021 kusvika 2023

Kuwedzera kwekushandiswa kunoratidzika kwepolyethylene kunogumira, uye chiyero chekuzvigadzirisa chinochengetedza kukura.Muna 2022, kushandiswa kuri pachena kwepolyethylene muChina kwakawedzera ne 0.1% gore negore, uye chiyero chekuzvigadzirisa chakawedzera ne 3.7 percent percent kana zvichienzaniswa negore rapfuura.
Huwandu hwekupinza kwepolyethylene muChina hwakadzikira gore negore, ukuwo huwandu hwekutengesa kunze kwenyika huchiwedzera gore negore.Muna 2022, China polyethylene yekupinda vhoriyamu yakadzikira ne7.7% gore-pa-gore;Kutengeswa kunze kwenyika kwakawedzera ne41.5%.China inoramba iri mutengesi wepolyethylene kunze kwenyika.Kutengeserana kwepolyethylene yeChina kunonyanya kutsamira pakutengeserana kwakawanda, kuverengera 82.2% yehuwandu hwekupinza huzhinji;Inotevera ndeyekutengesa kunze kwekugadzirisa kutengeserana, inoverengera 9.3%.Zvinotengeswa kunze kwenyika zvinonyanya kubva kunyika kana matunhu akaita seSaudi Arabia, Iran, neUnited Arab Emirates, zvichitora chikamu chinosvika 49.9% chezvose zvinotengeswa kunze kwenyika.
Polyethylene inoshandiswa zvakanyanya muChina, ine firimu accounting inopfuura hafu yehuwandu.Muna 2022, firimu rakatetepa rinoramba riri rakakura kudzika pasi pekushandisa munda we polyethylene muChina, ichiteverwa nekuumbwa kwejekiseni, pombi mbiri, hollow uye mamwe minda.
Polyethylene yekuChina ichiri mudanho rekukura nekukurumidza.Zvinoenderana nehuwandu husina kukwana, China inoronga kuwedzera gumi neshanu seti yemiti yepolyethylene gore ra2024 risati rasvika, nekuwedzera kwekugadzira kweanodarika matani mamirioni masere pagore.
2023 PE Domestic New Chishandiso Kugadzira Chirongwa

Kubva muna Chivabvu 2023, huwandu hwese hwekugadzira hwezvidyarwa zvePE zvirimwa hwasvika 30.61 miriyoni matani.Panyaya yekuwedzera kwePE muna 2023, zvinotarisirwa kuti huwandu hwekugadzira huve matani 3.75 miriyoni pagore.Parizvino, Guangdong Petrochemical, Hainan Refining uye Chemical, uye Shandong Jinhai Chemical yakaiswa mukushanda, iine huwandu hwekugadzira huwandu hwematani 2.2 miriyoni.Inosanganisira yakazara density mudziyo wematani miriyoni 1.1 uye HDPE mudziyo wematani miriyoni 1.1, nepo LDPE mudziyo hausati waiswa kushanda mukati megore.Muchikamu chechipiri chegore rinotevera, kuchine 1.55 miriyoni matani / gore rezvirongwa zvitsva zvekugadzira michina, zvinosanganisira 1.25 miriyoni matani eHDPE michina uye 300000 matani emidziyo yeLLDPE.Zvinotarisirwa kuti huwandu hwese hwekugadzira hweChina huchasvika 32.16 miriyoni matani panosvika 2023.
Parizvino, pane kupokana kwakakomba pakati pekupa uye kudiwa kwePE muChina, iine yakanyanya kusimba kugadzirwa kwezvikamu zvitsva zvekugadzira mune inotevera nhanho.Nekudaro, iyo indasitiri yezvigadzirwa zvepasi yakatarisana nekuoma kwemitengo yezvinhu, yakaderera zvigadzirwa odha, uye kuomerwa nekuwedzera mitengo pakupera kwekutengesa;Kudzikira kwemari yekushanda pamwe nemitengo yakakwira yekushanda kwakakonzera kuyerera kwemari kumabhizinesi, uye mumakore achangopfuura, pasi pekukwira kwemitengo yakakwira, mitemo yekusimbisa mari yekune dzimwe nyika yakawedzera njodzi yekuderera kwehupfumi, uye kushaikwa kusina simba kwakakonzera kudzikiswa. mumaodha ekutengeserana kunze kwenyika kune zvigadzirwa.Mabhizinesi echigadzirwa akadzika, senge zvigadzirwa zvePE, ari munguva yekurwadziwa kwemaindasitiri nekuda kwekupa uye kuda kusaenzana.Kune rimwe divi, ivo vanofanirwa kutarisisa kudiwa kwechinyakare, uku vachigadzira kutsva kutsva uye kutsvaga mafambiro ekunze kwave
Kubva pachikamu chekugoverwa kwekudzika kwePE kushandiswa muChina, chikamu chikuru chekushandiswa ifirimu, rinoteverwa nezvikamu zvikuru zvechigadzirwa zvakadai sekugadzira jekiseni, pombi, hollow, kudhirowa kwewaya, tambo, metallocene, coating, nezvimwewo. iyo huru ifirimu rekurima, firimu remaindasitiri, uye chigadzirwa chekurongedza firimu.Nekudaro, mumakore achangopfuura, kudiwa kwezvinhu zvechinyakare zvinoraswa zvepurasitiki zvemufirimu zvakatsiviwa zvishoma nezvishoma nekuzivikanwa kwemapurasitiki anoparara nekuda kweiyo shoma mitemo yepurasitiki.Uye zvakare, iyo yekurongedza indasitiri yefirimu iri zvakare munguva yekugadziriswa kwemaitiro, uye dambudziko rekuwandisa mune yakaderera-magumo zvigadzirwa richiri rakakura.
