[Isingeniso] : Kusukela ngo-2020, i-polyethylene yaseChina isingene emzuliswaneni omusha wokunwetshwa kwamandla aphakathi nendawo, futhi umthamo wayo wokukhiqiza uyaqhubeka nokukhula, ngamathani ayizigidi ezingu-2.6 womthamo wokukhiqiza omusha ngo-2023, kanye nengqikithi yamathani ayizigidi ezingu-32.41 zomthamo wokukhiqiza we-polyethylene , ukwanda ngo-8.72% uma kuqhathaniswa no-2022; Ngo-2023, ukukhiqizwa kwe-polyethylene yaseChina kulindeleke ukuthi kube amathani ayizigidi ezingama-28.1423, okuwukukhuphuka ngo-11.16% ngo-2022.

Kusukela ngo-2019 kuya ku-2023, umthamo wokukhiqiza we-polyethylene waseChina ukhule kancane kancane, ngesilinganiso sokukhula esiyinhlanganisela esingu-13.31%. Kusukela ngo-2020, ngokukhula kwamabhizinisi endawo, i-polyethylene ingene emzuliswaneni omusha wesikhathi sokunwetshwa endaweni eyodwa, egameni lamabhizinisi i-Wanhua Chemical, i-Zhejiang Petrochemical kanye ne-Lianyungang Petrochemical, izinto zokusetshenziswa ze-polyethylene zihlukahluka kakhulu, futhi izwi lamabhizinisi endawo lithuthuka njalo. .

Ngemuva kuka-2020, i-China ingene enkathini yokucwenga okukhulu kanye nokwandiswa kwamandla amakhemikhali, ngokuthuthukiswa kwamaphrojekthi wokucwenga kanye nokuhlanganiswa kwamakhemikhali kanye nokwenza kahle okuqhubekayo nokuthuthukiswa kwesakhiwo sezimboni, ithonya lemakethe liyaqina, futhi ukuncika ekuthengisweni kwe-polyethylene nakho kuyaqina. kancane kancane ukwehla, futhi ukuncika ekuthengisweni kwe-polyethylene kulindeleke ukuthi kwehle cishe ku-32% ngo-2023. Ngokombono wesakhiwo somkhiqizo jikelele wemboni yasekhaya, nakuba ingxenye yezinto ezikhethekile ikhulile, ingxenye yezinto ezijwayelekile zisalokhu kakhulu. enkulu, i-homogenization ibucayi, futhi ukuncintisana kwamabhizinisi kuya ngokuya kuqina.

Ngo-2023, kuzokwengezwa amathani ayizigidi ezingu-2.6 omthamo wokukhiqiza we-polyethylene, kanti i-HDPE nokufakwa kwe-full-density kuseyiyona eyinhloko, lapho umthamo wokukhiqiza we-HDPE uzokwenyuka ngamathani ayizigidi ezingu-1.9 kanye namandla okukhiqiza e-LLDPE azokwenyuka ngamathani angu-700,000. . Ngokwesifunda, amabhizinisi afakwe ekukhiqizeni agxile kakhulu eSouth China, amandla amasha okukhiqiza eSouth China afinyelela amathani ayizigidi eziyi-1.8, okubalelwa ku-69.23% wokwanda konyaka, kanye nengcindezi yokuhlinzeka eNingizimu China. Ngo-2023, umthamo wokukhiqiza we-polyethylene waseChina wawungu-32.41 wamathani ayizigidi, okuwukunyuka ngo-8.72% uma kuqhathaniswa no-2022. Phakathi kwazo, i-HDPE inomthamo wamathani ayizigidi ezingu-15.115, i-LDPE inomthamo wamathani ayizigidi ezingu-4.635 (kuhlanganisa amathani ayizigidi ezingu-1.3 we-LDPE/EVA amayunithi okukhiqiza ngokubambisana), kanti i-LLDPE inomthamo wamathani ayizigidi eziyi-12.66.

Umthamo wemboni ye-polyethylene yaseShayina uyaqhubeka nokukhula, eqhutshwa ukwanda kokukhiqiza unyaka nonyaka, i-2023 i-polyethylene entsha yokukhiqiza amathani ayizigidi ezingu-2.6, amanani entengo kawoyela ongahluziwe we-superposition ehle kusukela ngonyaka odlule, ukusetshenziswa kwamandla kwamabhizinisi okukhiqiza kuye kwalungiswa, ukukhiqizwa kwanda kancane kancane. Ngokwezibalo ezivela ku-Longzhong Information, izinga lokukhula elihlanganisiwe lokukhiqizwa kwe-polyethylene e-China kusukela ngo-2019 kuya ku-2023 kulindeleke ukuthi libe ngu-12.39%, kanti umphumela wonyaka we-polyethylene e-China ngo-2023 kulindeleke ukuthi ube amathani ayizigidi ezingu-28.1423, ukukhuphuka ngo-11.16% uma kuqhathaniswa no-2022.

Ngo-2023, ukukhiqizwa kwe-HDPE polyethylene yaseChina kwabalelwa ku-46.50% womkhiqizo ophelele, ukukhiqizwa kwe-polyethylene ye-LLDPE kubalwe u-42.22% womkhiqizo usuphelele, ukukhiqizwa kwe-LDPE polyethylene kubalwe u-11.28% womkhiqizo ophelele, kanti imishini esetshenziswe ngo-2023 isasebenza. ubuswa i-HDPE namadivayisi agcwele ukuminyana, futhi isilinganiso sokuphumayo se-HDPE sinyukile. Ingxenye yokukhiqizwa kwe-LDPE ne-LLDPE yehle kancane.
