[Intshayelelo]: Ukususela ngo-2020, i-polyethylene yaseTshayina ingene kumjikelo omtsha wokwandiswa kwamandla aphakathi, kwaye amandla ayo emveliso ayaqhubeka nokukhula, ngeetoni ezi-2.6 zezigidi zamandla amatsha emveliso ngo-2023, kunye neetoni ezi-32.41 zezigidi zamandla emveliso ye-polyethylene, ukunyuka kwe-8.72% xa kuthelekiswa no-2022; Ngo-2023, imveliso ye-polyethylene yaseTshayina kulindeleke ukuba ibe ziitoni ezingama-28.1423 zezigidi, ukunyuka kwe-11.16% ngaphezu ko-2022.

Ukususela ngo-2019 ukuya ku-2023, amandla okuvelisa i-polyethylene yaseTshayina anda ngokuthe chu, ngesantya sokukhula okuhlanganisiweyo se-13.31%. Ukususela ngo-2020, ngokunyuka kwamashishini asekuhlaleni, i-polyethylene ingene kumjikelo omtsha wexesha lokwandiswa eliphakathi, egameni lamashishini i-Wanhua Chemical, i-Zhejiang Petrochemical kunye ne-Lianyungang Petrochemical, izinto ezikrwada ze-polyethylene zahlukahlukene ngakumbi, kwaye ilizwi lamashishini asekuhlaleni lihlala liphucuka.

Emva kowama-2020, iTshayina ingene kwixesha lokuphucula kakhulu amandla eekhemikhali, kunye nokuqhubela phambili kweeprojekthi zokucoca kunye nokudibanisa iikhemikhali kunye nokuphuculwa okuqhubekayo kunye nokuphuculwa kwesakhiwo semizi-mveliso, impembelelo yemarike nayo iyaqina, kwaye ukuxhomekeka ekungenisweni kwe-polyethylene nako kuyehla kancinci kancinci, kwaye ukuxhomekeka ekungenisweni kwe-polyethylene kulindeleke ukuba kwehle kuye kuthi ga kwi-32% ngo-2023. Ngokwembono yesakhiwo semveliso iyonke kushishino lwasekhaya, nangona umlinganiselo wezinto ezikhethekileyo unyukile, umlinganiselo wezinto eziqhelekileyo usemkhulu kakhulu, ukuhambelana kwezinto kukhulu, kwaye ukhuphiswano lwamashishini luya lukhula ngakumbi.

Ngowama-2023, kuza kongezwa iitoni ezizizigidi ezi-2.6 zemveliso ye-polyethylene, apho i-HDPE kunye nokufakelwa okupheleleyo kusezezona ziphambili, apho amandla emveliso ye-HDPE aza kunyuka ngeetoni ezizizigidi ezili-1.9 kwaye amandla emveliso ye-LLDPE aza kunyuka ngeetoni ezingama-700,000. Ngokwemimandla, amashishini afakwe kwimveliso agxile kakhulu eMzantsi China, amandla emveliso amatsha eMzantsi China afikelela kwiitoni ezizizigidi ezili-1.8, nto leyo ebangela i-69.23% yokwanda konyaka, kwaye uxinzelelo lokubonelela eMzantsi China lwanda. Ngowama-2023, amandla emveliso ye-polyethylene yaseTshayina afikelela kwiitoni ezizizigidi ezingama-32.41, ukunyuka kwe-8.72% xa kuthelekiswa nowama-2022. Phakathi kwazo, i-HDPE inomthamo weetoni ezizizigidi ezili-15.115, i-LDPE inomthamo weetoni ezizizigidi ezi-4.635 (kubandakanya iitoni ezizizigidi ezi-1.3 zeeyunithi zemveliso ye-LDPE/EVA), kwaye i-LLDPE inomthamo weetoni ezizizigidi ezili-12.66.

Umthamo weshishini le-polyethylene eTshayina uyaqhubeka nokukhula, uqhutywa kukwanda kwemveliso unyaka nonyaka, umthamo omtsha wemveliso ye-polyethylene ka-2023 weetoni ezizigidi ezi-2.6, amaxabiso eoli ekrwada e-superposition ehle ukusuka kwinqanaba eliphezulu lonyaka ophelileyo, ukusetyenziswa kwamandla eenkampani zemveliso kuye kwalungiswa, imveliso yanda ngokuthe chu. Ngokwezibalo ezivela kwiLongzhong Information, izinga lokukhula kwemveliso ye-polyethylene eTshayina ukususela ngo-2019 ukuya ku-2023 kulindeleke ukuba libe yi-12.39%, kwaye imveliso yonyaka ye-polyethylene eTshayina ngo-2023 kulindeleke ukuba ibe ziitoni ezingama-28.1423 ezigidi, ukunyuka kwe-11.16% xa kuthelekiswa no-2022.

Ngowama-2023, imveliso ye-polyethylene ye-HDPE yaseTshayina yaba yi-46.50% yemveliso iyonke, imveliso ye-polyethylene ye-LLDPE yaba yi-42.22% yemveliso iyonke, imveliso ye-polyethylene ye-LDPE yaba yi-11.28% yemveliso iyonke, kwaye izixhobo eziqaliswe ukusebenza ngo-2023 zisalawulwa yi-HDPE kunye nezixhobo ezigcweleyo, kwaye umlinganiselo wemveliso ye-HDPE unyukile. Umlinganiselo wemveliso ye-LDPE kunye ne-LLDPE wehle kancinci.
