Mumakore achangopfuura, indasitiri yeChina ye polyethylene yakaramba yakamira yakasimba yebudiriro, nekukura kwekubuda uye kushandiswa kuri kutungamira pasirese.Panguva imwecheteyo, China ichiri mutengesi mukuru wepolyethylene munyika.Nekudaro, pamwe nekukurumidza kusimudzira kweindasitiri, kupesana kwemaitiro kwakabuda zvishoma nezvishoma, sekunge kuwanda kwezvigadzirwa zvepakati uye zvakaderera, kukwikwidza kwakakomba kwehomogeneous, uye dambudziko rekurasikirwa kweyuniti.Naizvozvo, ndiyo yakakosha kutungamira kweindasitiri kusimudzira kukwidziridzwa kwechigadzirwa chimiro chezve polyethylene zvigadzirwa uye kuziva chigadzirwa hunyanzvi, kusiyanisa, kwepamusoro-kuguma, girinhi uye kugadzirisa.Icho chinhu chakakosha zvakare kuti mabhizinesi abate mukana pasi pemakwikwi anotyisa mune ramangwana indasitiri.

Parizvino, polyethylene inonyanya kushandiswa muminda 5 inotevera, firimu, jekiseni kuumba, buri uye kudhirowa, pombi.Nekuvandudzwa kwemunda unoparara, polyethylene inosungirwa kubata imwe musika mugove, nepo mamwe UHMWPE, MLLDPE, EVA uye POE elastomers ichapa zvakanakira zvigadzirwa muminda mishanu, yakadai seyepamusoro-kuguma lithium bhatiri diaphragm, photovoltaic packaging firimu. , photovoltaic packaging agent uye yepamusoro-yekupedzisira munda wekurongedza firimu uye mauto Marine field applications.

Muna 2022, kugadzirwa kwepolyethylene yekuChina kuchawedzera kusvika pamamiriyoni makumi maviri nepfumbamwe nemazana masere nerimwe pagore, neavhareji yekukura kwepagore ye12.32%, uye icharamba ichiwedzera kukurumidza kwe12% mumakore mashanu anotevera.Naizvozvo, kukwidziridzwa kwechigadzirwa chimiro ndiwo maitiro eThe Times.Mabhizinesi ekugadzira emudzimba polyethylene akakamurwa kuitaHDPE, LDPEuye DFPE mhando nhatu dzemidziyo, iyo mitatu iri pamusoro apa midziyo inomiririra 44%, 16% uye 40% yehuwandu hwese zvichiteerana.Parizvino, nekukurumidzira kukura kweindasitiri yepolyethylene yeChina, kuitira kugadzirisa kupokana kwechimiro che "yakawandisa yakaderera-yekupedzisira zvigadzirwa uye kushayikwa kwezvinhu zvepamusoro-soro", iyo maindasitiri maitiro achachinja kune kusiyanisa uye yakakwirira-kuguma.Kuti ubate musika wevatengi wenguva yemberi, hunyanzvi hwechigadzirwa, kusiyanisa uye kuguma kwepamusoro kwave pedyo.

Parizvino, kune marudzi matatu ezvigadzirwa zvepurasitiki zvepamusoro-soro zvinogona kugadzirwa muzvivako zvekutanga zvekugadzira zvebhizimisi, zvinoti MLLDPE (metallocene polyethylene), UHMWPE (ultra-high molecular weight polyethylene) uye EVA;POE elastomer uye zvigadzirwa zvepurasitiki zvinoparara zvinoda kugadzirwa nemudziyo mutsva.Mhando shanu dzezvigadzirwa ndedzemhando dzepurasitiki dzepamusoro-soro dzine mitengo yakakwira, purofiti yakawanda uye tarisiro yakafara.Inotungamirirwa nechinangwa che "double carbon" uye mitemo yekuchengetedza zvakatipoteredza, China, semutengi mukuru, ichatora mukana wemhepo yekumabvazuva yepurogiramu, ine simba risingagumi uye ramangwana rinovimbisa.
