[Introduction] : Kutanga kubva muna 2020, polyethylene yekuChina yakapinda muchikamu chitsva chekuwedzera simba repakati, uye huwandu hwayo hwekugadzira huri kuramba huchiwedzera, iine 2.6 miriyoni matani ehunyanzvi hwekugadzira muna 2023, uye inosvika 32.41 miriyoni matani ekugadzira polyethylene. , kuwedzera kwe8.72% zvichienzaniswa ne2022; Muna 2023, kugadzirwa kwepolyethylene yekuChina kunotarisirwa kuita 28.1423 miriyoni matani, kuwedzera kwe11.16% pamusoro pe2022.

Kubva 2019 kusvika 2023, China yekugadzirwa kwe polyethylene yakawedzera zvishoma nezvishoma, nekukura kwechikamu che13.31%. Kubva 2020, nekusimuka kwemabhizinesi emuno, polyethylene yakapinda mudenderedzwa nyowani yepakati yekuwedzera nguva, yakamiririra mabhizinesi Wanhua Chemical, Zhejiang Petrochemical uye Lianyungang Petrochemical, polyethylene raw materials yakawedzera kusiyanisa, uye izwi remabhizinesi emuno riri kuramba richivandudza. .

Mushure megore ra2020, China yakapinda munguva yekunatswa kukuru uye kuwedzera kwemakemikari ekuwedzera, nekufambira mberi kwekunatsa uye mapurojekiti ekubatanidza makemikari uye kuenderera mberi kwekugadzirisa uye kuvandudzwa kwechimiro cheindasitiri, pesvedzero yemusika iri kusimbisa zvakare, uye kutsamira kune polyethylene kunze kwenyika kuri zvakare. zvishoma nezvishoma zvichiderera, uye kuvimba kwepolyethylene kunze kwenyika kunotarisirwa kudonha kusvika pa32% muna 2023. Kubva pakuona kwehuwandu hwekugadzirwa kwezvigadzirwa zvemabhizimisi epamba, kunyange zvazvo chikamu chezvigadzirwa zvakakosha chakawedzera, chikamu chezvinhu zvakajairika zvichiri zvakare. hombe, homogenization yakakomba, uye makwikwi emabhizinesi ari kuwedzera kuwedzera.

Muna 2023, huwandu hwemamiriyoni mazana maviri nemazana matanhatu ematani ekugadzira polyethylene ichawedzerwa, iine HDPE uye yakazara-density yekumisikidza ichiri iyo huru, iyo HDPE yekugadzira huwandu huchawedzera nematani 1.9 miriyoni uye LLDPE kugadzirwa huchawedzera ne700,000 matani. . Nedunhu, mabhizinesi anoiswa mukugadzira anonyanya kutariswa muSouth China, South China hutsva hwekugadzira huwandu hwakazara matani miriyoni 1.8, inoverengera 69.23% yekuwedzera kwegore, uye kumanikidzwa kwekupa muSouth China kwakawedzera. Muna 2023, kugadzirwa kwe polyethylene yeChina kwakasvika mamiriyoni makumi matatu nemaviri emakumi mana nemazana mana, kuwedzera kwe8,72% zvichienzaniswa ne2022. Pakati pavo, HDPE ine simba remamiriyoni e15.115 emamiriyoni, LDPE ine simba remamiriyoni e4.635 (kusanganisira 1.3 mamiriyoni eLDPE / EVA matani e1. Co-production units), uye LLDPE ine huwandu hwematani 12.66 miriyoni.

China's polyethylene indasitiri indasitiri inoenderera mberi nekuwedzera, ichisundwa nekuwedzera kwekugadzira gore negore, 2023 polyethylene nyowani yekugadzira matani 2.6 miriyoni matani, superposition mafuta asina kuchena mitengo yakadonha kubva pakakwirira gore rapfuura, mabhizinesi ekugadzira kugona kushandiswa kwakagadziriswa, kugadzirwa kwakawedzera zvishoma. Zvinoenderana nehuwandu kubva kuLongzhong Ruzivo, huwandu hwekukura kwehuwandu hwekugadzirwa kwepolyethylene muChina kubva muna 2019 kusvika 2023 hunotarisirwa kuita 12.39%, uye kuburitswa kwepagore kwe polyethylene muChina muna 2023 kunotarisirwa kuita 28.1423 miriyoni matani, kuwedzera kwe11.16% zvichienzaniswa ne2022.

Muna 2023, kugadzirwa kweChina kweHDPE polyethylene kwakaverengera 46.50% yezvakabuda, LLDPE polyethylene kugadzirwa kwakaverengera 42.22% yezvakabuda, LDPE polyethylene kugadzirwa kwakaverengera 11.28% yezvakabuda, uye zvishandiso zvakaiswa muna 2023 zvichiri. inotongwa neHDPE uye yakazara-density zvishandiso, uye chiyero chekubuda cheHDPE chawedzera. Chikamu cheLDPE neLLDPE kugadzirwa chakadzikira zvishoma.
