Kusukela ngo-December 15, umkhuba wenzuzo wezinto zokusetshenziswa ezihlukene ze-polyethylene iyonke ubonise ukuthambekela okukhuphukayo, futhi inzuzo ye-ethylene ezinhlotsheni ezinhlanu zezinqubo inyuke kakhulu, isuka ku-+650 yuan/ton yaya ku-460 yuan/ton ekuqaleni. yenyanga; Kulandelwa inzuzo yamalahle namafutha ekuqaleni kwenyanga +212 yuan/ton kanye +207 yuan/ton to -77 yuan/ton kanye 812 yuan/ton; Okokugcina, inzuzo ye-methanol kanye nenzuzo ye-ethane, kusukela ku-+120 yuan/ton kanye +112 yuan/ton kuya ku-70 yuan/ton kanye no-719 yuan/ton ekuqaleni kwenyanga. Phakathi kwazo, ukukhiqizwa kwe-methanol ne-ethylene kwenza inzuzo kusuka kokubi kuya kokuhle. Inzuzo yamalahle kanye ne-ethane inyuke ngo-34.21% kanye no-18.45% kusukela ekuqaleni kwenyanga.

Okokuqala, inzuzo yenqubo ye-ethylene ikhuphuke kakhulu, ekuqaleni kwenyanga ukwanda komthwalo webhizinisi lokukhiqiza okuyinhloko, i-superposition esekela amadivaysi awela phansi aneziqu ezihlukene zokunciphisa umthwalo noma ukupaka, ukuthunyelwa komfula kwanda, abasebenzisi abangaphansi komfula wempahla eluhlaza uma kuqhathaniswa, isidingo sendawo sivilapha, okwenza insimu ibe sesimweni sokugcwala ngokweqile. Ngemva kwenani eliphezulu lezinto zokusetshenziswa kanye nokwenyuka kwengcindezi yezindleko kulezi zici ezimbili, inhloso yokuthenga ezansi nomfula i-ethylene icindezelekile, futhi ukugxila kwezingxoxo zemakethe kuphansi. Ngakho-ke, izindleko zendlela yokukhiqiza i-ethylene zilandela ukwehla, kusukela ngomhlaka-15, izindleko zaziyi-7660 yuan/ton, okwakungu -6.13% kusukela ekuqaleni kwenyanga.

Mayelana nendlela yenqubo yamalahle, igagasi elibandayo eliqine kakhulu lisanda kuhlasela izindawo eziningi zezwe lethu kulobu busika, esimweni sokwehla kweqhwa elinamandla ngokuzumayo, imakethe ayiphumanga ngenxa yokwethuka kwesitoko, intengo yomsuka iyehla ngisho, okwangempela. khuphuka impahla kuphela. Igagasi elibandayo alizange likukhuphule kakhulu ukusebenza kwentengo yendawo yokukhiqiza, intengo iqhubeka nesigqi sekhotheshini esithe thuthu samalahle ngesonto eledlule, lapho iqhwa lincibilika, intengo izoba sendaweni yokukhiqiza/impahla phambi kwendawo yokugcina izimpahla kanye nokubanda. qhweba uye eningizimu ukuze uqalise umdlalo. Izindleko zamalahle inyanga nenyanga -0.77% ngo-7308 yuan/ton.

Mayelana nendlela yenqubo kawoyela, amanani entengo kawoyela akamuva axubile, futhi isizathu esibi ukuthi ukukhathazeka kwemakethe mayelana nombono wokufunwa kusekhona. Isizathu esihle sokufakwa kwempahla kawoyela ongahluziwe ohweba e-US kwehle kakhulu kunalokho obekulindelwe, kuhlanganiswe ne-Federal Reserve eshiwo ekuncishisweni kwezinga lenzalo kathathu ngonyaka ozayo. Njengamanje, amanani kawoyela emhlabeni wonke aphinde afinyelela eqophelweni eliphansi kakhulu onyakeni, futhi umkhathi obuthakathaka awukaqedwa ngokuphelele. Ukuzamazama ngemva komhlangano we-OPEC+ kuhlanganiswe nengcindezi evela kumbono wesidingo esibuthakathaka kwakuyizinto eziyinhloko. Kodwa-ke, kulo nyaka, i-$ 70- $ 72 isengaphansi eqinile ku-Brent, futhi kulindeleke ukuthi amanani kawoyela asenayo indawo yokulungisa phezulu. Izindleko zamanje zokukhiqiza uwoyela yi-8277 yuan/ton, okuyi--2.46% kusukela ekuqaleni kwenyanga.
