Ngokusho kolwazi lokuhlela iphrojekthi yomphakathi, imboni ye-polyethylene ingakhulula amathani ayizigidi ezingu-2.2 / ngonyaka wamandla okukhiqiza esikhathini esingaphansi kwezinyanga ezimbili.Lokhu ngokungangabazeki "kubi kakhulu" emakethe ye-polyethylene, esivele inokuncintisana kakhulu.Ngaleso sikhathi, ukuncintisana kwemboni kuzoqina, futhi izindleko zizohlehliswa noma zibe ezejwayelekile.
Njengoba i-polyethylene yaseShayina ingena enkathini yokucwenga ngezinga elikhulu kanye nokwanda kwamandla, amandla okukhiqiza akhule kakhulu.Ngesikhathi esifanayo, izinsiza ezisanda kwethulwa ziyimikhiqizo yamanani aphansi.Unyaka wezi-2021 unyaka wokunwetshwa kwamandla okugxilile we-polyethylene, ngamathani ayizigidi ezi-4.4 wamandla amasha ngonyaka kanye nokukhula kwamandla angama-20%.Ngokusho kwalolu hlelo, umthamo omusha wokukhiqiza i-polyethylene kulo nyaka ungamathani ayizigidi ezingu-3.95 / ngonyaka.Kusukela ekupheleni kuka-Okthoba, amandla okukhiqiza asetshenziswe amathani ayizigidi ezingu-1.75 ngonyaka.Kusenezigidi ezingu-2.2 zamathani/unyaka amandla okukhiqiza ngonyaka azofakwa ekukhiqizeni.Ukwengeza, kusukela ngo-2023 kuya ku-2024, kusenezingxenye eziyizigidi ezingu-4.95 ze-t/a ezihlelelwe ukukhiqizwa e-China, kuhlanganise namayunithi ama-3 ahlelelwe ukukhiqizwa ngo-2023, afaka umthamo we-1.8 million t/a.Uma amandla okukhiqiza angenhla esetshenziswa njengoba kuhleliwe, imakethe ye-polyethylene izoba yangaphakathi kakhulu.
Ukukhululwa okugxilile kwamandla okukhiqiza kuzokwandisa ingcindezi yokusebenza kwamabhizinisi okukhiqiza i-polyethylene.Imakethe ye-polyethylene ngo-Okthoba wokuqala walo nyaka yayiyivila kakhulu kusukela ngo-2008. Engxenyeni yokuqala yonyaka, ethintekile ngokunyuka okuqhubekayo kwamanani entengo kawoyela ongahluziwe wamazwe ngamazwe, ukusekelwa kwezindleko kwakunamandla, futhi intengo evamile ye-polyethylene imakethe yayiphakeme kunaleyo esikhathini esifanayo sika-2021. Nokho, ngemva kokungena engxenyeni yesibili yonyaka, imakethe ye-polyethylene ayizange yenze ngendlela egculisayo, futhi ngisho nentengo yashaya phansi okusha cishe iminyaka emibili ngo-August.Inkathi ephakeme kakhulu ‘yegolide eyisishiyagalolunye nesiliva eyishumi’ ayizange iphumelele.Ikakhulukazi, ngenxa yezindleko eziphezulu, izindleko zamafutha enziwe nge-polyethylene ziyaqhubeka zibheke phansi.Ngisho nangenkathi yokuthengisa ephezulu, lesi simo asizange sibe ngcono kakhulu, nokulahlekelwa cishe kwama-yuan angu-1000 ngethani lemikhiqizo.Ngaphezu kwalokho, ngenxa yomthelela ophindaphindiwe walolu bhubhane, ingcindezi yokusungula yamabhizinisi okukhiqiza iphezulu, okungase kuholele empini yamanani.
Ngesikhathi esifanayo, isimo somnotho samazwe ngamazwe sibi ngenxa yomthelela obanzi wokuqiniswa kwezinqubomgomo zezimali eYurophu nase-United States, izingxabano zezwe kanye nokuqubuka kwezindawo eziningi.Ngakho-ke, ama-oda aphansi omfula we-polyethylene ancishisiwe wonke, futhi amandla okugcwalisa izimboni ezibulalayo ancishisiwe kakhulu.Isikhathi esiningi, imodi yokusebenza ye-inventory ephansi iye yagcinwa, ngaleyo ndlela kuvimbela isidingo se-polyethylene.Ngaphezu kwalokho, ngokuphoqelelwa kokuvinjelwa kwepulasitiki kanye nama-oda okuvinjelwa aqiniswayo, amapulasitiki abolayo azophinde athathe indawo yesidingo endaweni yokupakisha ye-polyethylene.
Imakethe yasekhaya ye-polyethylene ikakhulukazi ibuthakathaka, futhi izinhlobo ezintathu zamabala ezinkulu zehlisiwe zaba ngamazinga ahlukahlukene.Imakethe ye-LLDPE ikhombise ukuthambekela kokukhuphuka kuqala bese iwa, kuyilapho i-LDPE ne-HDPE ikhombise umkhuba wokuwa kuqala bese izinza.Ngesonto, intengo yefekthri ye-polyethylene yehliswe kakhulu ngo-50-400 yuan/ton.Ngokwesidingo, umdwebo wamanje wezintambo ezinengcindezi ephansi kanye nepayipi kusenkathini engasebenzi, enama-oda ambalwa kanye nesidingo esibuthakathaka esiphansi somfula.Mayelana nokuhlinzekwa, muva nje, amanye amabhizinisi anciphise umkhiqizo wawo mayelana nokugcinwa kwemishini.Ngaphezu kwalokho, ekupheleni kwenyanga, amabhizinisi azimisele ukuya endaweni yokugcina impahla ekupheleni kwenyanga, futhi ikakhulukazi enze inzuzo eyengeziwe yokuthunyelwa.Nokho, imakethe yamafilimu apakishwayo yamanje ivuma ngenxa ye-“Double 11” futhi isidingo sizinzile.Isimo sengqondo sabathengisi sivamile, futhi ikhotheshini ilungiswa ebangeni elincane, futhi isimo sisonke naso asinamandla.
Ukuntengantenga kwemakethe yekusasa lika-Liansu akukukhulu, okuletha ukwesekwa okulinganiselwe endaweni.Ngomhla zingama-27 kuMfumfu, intengo yokuvula ye-polyethylene futures 2301 yayingu-7676, inani eliphakeme kakhulu lalingu-7771, inani eliphansi lalingu-7676, intengo yokuvala yayingu-7692, inani lemali yangaphambilini lalingu-7704, inani lokukhokhela lalingu-7713, lehle ngo-12, ukuhweba. umthamo wawungu-325,306, isikhundla sasingu-447,371, futhi isikhundla sansuku zonke sanyuswa ngo-2302. (Iyunithi yokucaphuna: yuan/ton)
Mayelana nezimpahla zamanje zokusetshenziswa, uwoyela ongahluziwe wamazwe ngamazwe ukhuphukile, okulethe ukusekelwa okuthile ohlangothini lwezindleko.Ngasohlangothini lwesidingo, amapayipi anengcindezi ephansi nezinto zokudweba ngezintambo zisesikhathini esingekho, futhi isidingo sefilimu ebamba ukushisa siyaphela.I-downstream iyaqaphela, futhi i-Duowei yenza ngokwesidingo, ngakho umdlandla usuphenduke waba buthaka.Ngasohlangothini lokunikezela, umkhiqizo wemakethe wehlile muva nje.Kulindeleke ukuthi imakethe yendawo ye-polyethylene izohlala ibuthakathaka esikhathini esifushane, kodwa isikhala esiwayo silinganiselwe.
Izinto eziningi ezingezinhle kudala zicindezela isimo semakethe.IJinjiu yalo nyaka inethemba eliqinile lemakethe lemakethe engcono.Ngesikhathi esifanayo, izinzuzo ezingenhla zinikeza isiqalo samabhizinisi.Isifiso sokuqagela sivutha ngokushesha, futhi isikhungo samanani sikhuphuka kakhulu.Kodwa-ke, kufanele kuqashelwe ukuthi ukucindezela okuphelele kokuhlinzekwa kwemakethe kusekukhulu: amanye amayunithi aqalwe kabusha ekuqaleni, futhi ukulahlekelwa kwesondlo ngoSeptemba kulindeleke ukuba kwehle kakhulu;Mayelana nokukhiqizwa okusha, i-Lianyungang Petrochemical Phase II amathani angu-400000 okucindezela okuphansi afakwe ekukhiqizeni;Ethintwe isidingo esibuthakathaka se-polyethylene evela phesheya, inani elikhulu lezimpahla zenani eliphansi lithululelwe eShayina, futhi ukufika kokungenisa kwanda.Ngaphezu kwalokho, uma kucatshangelwa ukuthi kunzima ukuvela kwesidingo ngokusobala, imakethe yendawo ibuswa ukuthengiselana phakathi kwabahwebi, futhi isimo esiwubhubhane siyaqhubeka ezweni lonke, esingase sinqande ukuthambekela okukhulayo kwemakethe.Umbhali ukholelwa ukuthi esikhathini esifushane, kuzoba nokumelana okukhulu ukuze amanani aqhubeke nokukhuphuka.
