[Isingeniso]: Kusukela ngo-2020, i-polyethylene yaseShayina isingene emzuliswaneni omusha wokwandiswa kwamandla aphakathi, futhi amandla ayo okukhiqiza ayaqhubeka nokukhula, ngamathani ayizigidi ezingu-2.6 omthamo omusha wokukhiqiza ngo-2023, kanye namathani ayizigidi ezingu-32.41 omthamo wokukhiqiza i-polyethylene, ukwanda ngo-8.72% uma kuqhathaniswa no-2022; Ngo-2023, ukukhiqizwa kwe-polyethylene yaseShayina kulindeleke ukuthi kube ngamathani ayizigidi ezingu-28.1423, ukwanda ngo-11.16% ngaphezu kuka-2022.

Kusukela ngo-2019 kuya ku-2023, amandla okukhiqiza i-polyethylene yaseShayina anda kancane kancane, ngesilinganiso sokukhula okuhlanganisiwe esingu-13.31%. Kusukela ngo-2020, ngokukhula kwamabhizinisi endawo, i-polyethylene ingene emzuliswaneni omusha wesikhathi sokunwetshwa esihlanganisiwe, egameni lamabhizinisi i-Wanhua Chemical, i-Zhejiang Petrochemical kanye ne-Lianyungang Petrochemical, izinto zokusetshenziswa ze-polyethylene ziyahlukahluka kakhulu, futhi izwi lamabhizinisi endawo lihlala lithuthuka.

Ngemuva kuka-2020, iShayina ingene enkathini yokucwenga okukhulu kanye nokwanda kwamandla amakhemikhali, ngokuthuthuka kwamaphrojekthi okuhlanganisa ukucwenga kanye nokuhlanganiswa kwamakhemikhali kanye nokwenza ngcono okuqhubekayo kanye nokuthuthukiswa kwesakhiwo sezimboni, ithonya lemakethe nalo liyaqina, futhi ukuncika ekungenisweni kwe-polyethylene nakho kwehla kancane kancane, futhi ukuncika ekungenisweni kwe-polyethylene kulindeleke ukuthi kwehle kuye cishe ku-32% ngo-2023. Ngokombono wesakhiwo somkhiqizo sonke semboni yasekhaya, yize isilinganiso sezinto ezikhethekile sikhulile, isilinganiso sezinto ezijwayelekile sisakhulu kakhulu, ukuhlanganiswa kwezinto kukhulu, futhi ukuncintisana kwamabhizinisi kuya ngokuya kukhula.

Ngo-2023, kuzongezwa amathani ayizigidi ezingu-2.6 omthamo wokukhiqiza i-polyethylene, kanti ukufakwa kwe-HDPE kanye nobuningi obugcwele kuseyizona eziyinhloko, lapho umthamo wokukhiqiza i-HDPE uzokhuphuka ngamathani ayizigidi ezingu-1.9 kanti umthamo wokukhiqiza i-LLDPE uzokhuphuka ngamathani angu-700,000. Ngokwesifunda, amabhizinisi afakwa ekukhiqizeni agxile kakhulu eNingizimu China, umthamo wokukhiqiza omusha waseNingizimu China ufinyelele amathani ayizigidi ezingu-1.8, okwenza kube ngu-69.23% wokwanda konyaka, kanti ingcindezi yokuphakelwa eNingizimu China yanda. Ngo-2023, umthamo wokukhiqiza i-polyethylene waseShayina ufinyelele amathani ayizigidi ezingu-32.41, ukwanda ngo-8.72% uma kuqhathaniswa no-2022. Phakathi kwazo, i-HDPE inamandla angamathani ayizigidi ezingu-15.115, i-LDPE inamandla angamathani ayizigidi ezingu-4.635 (kufaka phakathi amathani ayizigidi ezingu-1.3 amayunithi okukhiqiza i-LDPE/EVA), kanti i-LLDPE inamandla angamathani ayizigidi ezingu-12.66.

Umthamo wemboni ye-polyethylene yaseShayina uyaqhubeka nokukhula, uqhutshwa ukwanda kokukhiqiza unyaka nonyaka, umthamo omusha wokukhiqiza we-polyethylene wamathani ayizigidi ezingu-2.6 ngo-2023, amanani kawoyela ongahluziwe we-superposition ehle kusukela phezulu ngonyaka odlule, ukusetshenziswa kwamandla ezinkampani zokukhiqiza kuye kwalungiswa, ukukhiqizwa kwanda kancane kancane. Ngokusho kwezibalo ezivela ku-Longzhong Information, izinga lokukhula kwe-polyethylene e-China kusukela ngo-2019 kuya ku-2023 kulindeleke ukuthi libe ngu-12.39%, kanti umkhiqizo waminyaka yonke we-polyethylene eShayina ngo-2023 kulindeleke ukuthi ube ngamathani ayizigidi ezingu-28.1423, ukwanda okungu-11.16% uma kuqhathaniswa no-2022.

Ngo-2023, ukukhiqizwa kwe-polyethylene ye-HDPE yaseShayina kwaba ngu-46.50% womkhiqizo ophelele, ukukhiqizwa kwe-polyethylene ye-LLDPE kwaba ngu-42.22% womkhiqizo ophelele, ukukhiqizwa kwe-polyethylene ye-LDPE kwaba ngu-11.28% womkhiqizo ophelele, kanti amadivayisi aqaliswe ukusebenza ngo-2023 asabuswa yi-HDPE kanye namadivayisi agcwele ubuningi, kanti isilinganiso somkhiqizo we-HDPE sinyukile. Ingxenye yokukhiqizwa kwe-LDPE kanye ne-LLDPE yehle kancane.
