Kwiminyaka yakutshanje, iimveliso ze-PE ziqhubekile ziqhubela phambili kwindlela yokwandiswa kwesantya esiphezulu. Nangona ukuthengwa kwempahla kumazwe angaphandle kwe-PE kusenomlinganiselo othile, ngokunyuka ngokuthe ngcembe kwamandla emveliso yangaphakathi, izinga le-PE lasekhaya libonise indlela yokukhula unyaka nonyaka. Ngokutsho manani Jinlianchuang kaThixo, ukususela 2023, amandla emveliso PE lwasekhaya ifikelele 30.91 yezigidi zeetoni, kunye nomthamo imveliso ngeenxa 27.3 yezigidi zeetoni; Kulindeleke ukuba kusekho i-3.45 yezigidi zeetoni zomthamo wemveliso owenziwe ekusebenzeni ngo-2024, ubukhulu becala bugxininiswe kwisiqingatha sesibini sonyaka. Kulindeleke ukuba umthamo wemveliso ye-PE ube yi-34.36 yezigidi zeetoni kwaye imveliso iya kuba malunga ne-29 yezigidi zeetoni ngo-2024.
Ukususela ngo-2013 ukuya ku-2024, amashishini okuvelisa i-polyethylene ahlulwe kakhulu abe ngamanqanaba amathathu. Phakathi kwabo, ukusuka ngo-2013 ukuya ku-2019, ikakhulu linqanaba lotyalo-mali lwamalahle kumashishini e-olefin, kunye nomndilili wokunyuka kwesikali semveliso yonyaka malunga neetoni ezingama-950000/ngonyaka; Ixesha elisuka ku-2020 ukuya ku-2023 linqanaba lemveliso elisembindini lokusulungekiswa okukhulu kunye neshishini lemichiza, apho umyinge wonyaka wemveliso e-China unyuke kakhulu, wafikelela kwi-2.68 yezigidi zeetoni ngonyaka; Kulindeleke ukuba i-3.45 yezigidi zeetoni zomthamo wemveliso isaza kuqaliswa ukusebenza ngo-2024, kunye nezinga lokukhula kwe-11.16% xa kuthelekiswa no-2023.
Ukungeniswa kwe-PE kumazwe angaphandle kubonise indlela ehlayo unyaka nonyaka. Ukusukela ngo-2020, ngolwandiso olugxininisiweyo lokusulungekiswa komyinge omkhulu, umthamo wezothutho wamazwe ngamazwe ubuqinile ngenxa yeziganeko zempilo yoluntu jikelele, kwaye amazinga okuthutha elwandle anyuke kakhulu. Ngaphantsi kweempembelelo zabaqhubi bexabiso, umthamo wokungenisa i-polyethylene yasekhaya unciphe kakhulu ukususela ngo-2021. Ukususela kwi-2022 ukuya kwi-2023, amandla okuvelisa e-China aqhubeka esanda, kwaye ifestile ye-arbitrage phakathi kweemarike zasekhaya kunye nezangaphandle ihlala kunzima ukuyivula. Umthamo wokungenisa we-PE wamazwe ngamazwe unciphile xa kuthelekiswa no-2021, kwaye kulindeleke ukuba umthamo wangaphakathi we-PE wangaphakathi uya kuba yi-12.09 yezigidi zeetoni ngo-2024. Ngokusekelwe kwindleko kunye nephethini yokuhamba kwemfuno yokubonelela-jikelele, ikamva okanye umthamo wasekhaya we-PE uya kuqhubeka. ukunciphisa.
Ngokumalunga nokuthunyelwa kwamanye amazwe, ngenxa yemveliso egxininisiweyo yokucocwa okukhulu kunye nokukhanya kweeyunithi ze-hydrocarbon kwiminyaka yamuva nje, amandla okuvelisa kunye nemveliso iye yanda ngokukhawuleza. Iiyunithi ezintsha zineeshedyuli ezininzi zemveliso, kwaye uxinzelelo lokuthengisa lunyukile emva kokuba iiyunithi zisebenze. Ukuqina kokhuphiswano lwasekhaya lwamaxabiso aphantsi kukhokelele kumonakalo wenzuzo phantsi kokhuphiswano lwexabiso eliphantsi, kwaye umahluko wexesha elide wexabiso eligqwethiweyo phakathi kweemarike zangaphakathi nezangaphandle kwenze kwanzima kubathengi besiphelo sokwetyisa isikali esinjalo sokunyuswa konikezelo ngexesha elifutshane. ixesha. Emva kowama-2020, umthamo wokuthunyelwa kwe-PE ukuya e-China ubonise umkhwa wokunyuka unyaka nonyaka.
Ngokunyuka koxinzelelo lokhuphiswano lwasekhaya unyaka nonyaka, umkhwa wokufuna uqhelaniso lokuthumela ngaphandle kwepolyethylene awunakuguqulwa. Ngokubhekiselele kwimpahla ephuma kumazwe angaphandle, uMbindi Mpuma, iMelika kunye nezinye iindawo zisenenani elikhulu lemithombo yexabiso eliphantsi, kwaye ziyaqhubeka nokuthatha i-China njengeyona marike inkulu ekujoliswe kuyo yokuthumela ngaphandle. Ngokunyuka kwamandla emveliso yasekhaya, ukuxhomekeka kwangaphandle kwe-polyethylene kuya kuncipha ukuya kuma-34% ngo-2023. Nangona kusekho ulindelo lokuhla kokuxhomekeka kwangaphandle notyalo-mali lwamandla emveliso yasekhaya, umsantsa wemfuno yeemveliso ezikumgangatho ophezulu awunakuzaliswa kwixesha elifutshane.
Ngokuphathelele ukuthunyelwa kwamanye amazwe, kunye nokuqiniswa ngokuthe ngcembe kokhuphiswano lwasekhaya kunye nokudluliselwa kwamanye amashishini asezantsi asezantsi kwi-Asia-mpuma ye-Asia, imfuno yangaphandle iye yaba ngumkhombandlela wokuhlola intengiso kumashishini emveliso kunye nabanye abarhwebi kwiminyaka yakutshanje. Kwixesha elizayo, iya kubangela uqhelaniso lokuthumela ngaphandle, ukwandisa ukuthunyelwa kwempahla kuMzantsi-mpuma Asia, eAfrika, nakuMzantsi Merika. Kwicala eliphakathi kwelizwe, ukuphunyezwa okuqhubekayo kweBhanti kunye neNdlela kunye nokuvulwa kwamazibuko ezorhwebo aseRashiya aseSino kuye kwadala amathuba okunyusa imfuno ye-polyethylene kwi-Northwest Central Asia kunye ne-Northeast Russian Far East.
