M'zaka zaposachedwa, makampani a polyethylene ku China akhala akutukuka kwambiri, ndikukula kwazinthu ndikugwiritsa ntchito kutsogolera padziko lonse lapansi.Panthawi imodzimodziyo, China idakali yogulitsa kunja kwa polyethylene padziko lonse lapansi.Komabe, pamodzi ndi chitukuko chofulumira cha mafakitale, kutsutsana kwapangidwe kwakhalako pang'onopang'ono, monga kuchuluka kwa zinthu zapakatikati ndi zotsika, mpikisano waukulu wa homogeneous, ndi vuto la kutayika kwa unit.Chifukwa chake, ndiye gawo lofunikira kwambiri pamakampani kuti alimbikitse kukweza kwazinthu zamtundu wa polyethylene ndikuzindikira luso lazogulitsa, kusiyanitsa, kutha, kubiriwira komanso makonda.Ndichinthu chofunikiranso kuti mabizinesi agwiritse ntchito mwayiwu pansi pa mpikisano wowopsa m'makampani amtsogolo.

Pakali pano, polyethylene makamaka ntchito zotsatirazi minda 5, filimu, jekeseni akamaumba, dzenje ndi kujambula, chitoliro.Ndi chitukuko cha munda degradable, polyethylene amakakamizika kulanda ena msika, pamene ena UHMWPE, MLLDPE, EVA ndi POE elastomers adzapereka ubwino wa mankhwala m'madera asanu, monga mkulu-mapeto lifiyamu batire diaphragm, photovoltaic ma CD filimu. , photovoltaic packaging agent ndi filimu yopangira mapepala apamwamba kwambiri komanso ntchito zankhondo za Marine field.

Mu 2022, mphamvu yopanga polyethylene yaku China idzawonjezeka mpaka matani 29.81 miliyoni / chaka, ndikukula kwapakati pa 12.32%, ndipo ikhalabe ndi liwiro lalikulu la 12% m'zaka zisanu zikubwerazi.Chifukwa chake, kukweza kwazinthu zomwe zidachitika ndi The Times.Makampani opanga ma polyethylene apanyumba amagawidwaZithunzi za HDPE, LDPEndi DFPE mitundu itatu ya zida, zida zitatu zomwe zili pamwambazi zimawerengera 44%, 16% ndi 40% ya mphamvu zonse motsatana.Pakalipano, ndi chitukuko chachangu cha mafakitale a polyethylene ku China, kuti athetse kutsutsana kwapangidwe kwa "mankhwala otsika kwambiri ndi kusowa kwa zinthu zamtengo wapatali", chitsanzo cha mafakitale chidzasintha kusiyanitsa ndi kutha.Pofuna kulanda msika wamtsogolo wa ogula pasadakhale, luso lazogulitsa, kusiyanitsa ndi kutha kwapamwamba kuli pafupi.

Pakalipano, pali mitundu itatu ya mankhwala apamwamba a pulasitiki omwe amatha kupangidwa m'mafakitale oyambirira a malonda, omwe ndi MLLDPE (metallocene polyethylene), UHMWPE (ultra-high molecular weight polyethylene) ndi EVA;POE elastomer ndi zinthu zapulasitiki zowonongeka ziyenera kupangidwa ndi chipangizo chatsopano.Mitundu isanu yazinthu izi ndi yamitundu yapulasitiki yapamwamba yokhala ndi mitengo yokwera, phindu lolemera komanso chiyembekezo chachikulu.Poyendetsedwa ndi cholinga cha ndondomeko ya "carbon double" ndi ndondomeko zoteteza chilengedwe, China, monga wogula wamkulu, idzagwiritsa ntchito mphepo yakum'mawa kwa ndondomekoyi, ndi mphamvu zopanda malire komanso tsogolo labwino.
