Muva nje, intengo yei-ethylene glycolaphinde abe sezingeni eliphansi, okuholele ekukhuphukeni kwamakhemikhali amaningi.Mayelana nalokhu, u-Shi Jiaping, umhlaziyi ophezulu we-Huarui Information, wachaza ukuthi, ngakolunye uhlangothi, ukukhishwa kwe-ethylene glycol side supply kwakusobala kakhulu.NgoNovemba, umthamo wokuqala we-ethylene glycol wasekhaya wehle wafinyelela ku-55% - 56%, kuyilapho igesi yokwenziwa ku-ethylene glycol yokuqala umthwalo wehle wafinyelela cishe ku-30% - 33%, ngokuyisisekelo ukwehla komlando.Ngakolunye uhlangothi, intengo ye-ethylene glycol iwile ezingeni eliphansi, eliye laphambuka kakhulu ekulinganisweni.Njengamanje, umuzwa wemakethe usufudumala, futhi imikhiqizo enokucindezela okweqile kwenzuzo esigabeni sokuqala idinga ukulungiswa.

Muva nje, ikusasa le-ethylene glycol lihlehlisiwe futhi laphakama, "eliyingqayizivele" emkhakheni we-polyester.Eqinisweni, bekuwuhlobo lokulungiswa kokulinganisa ngemuva kokuthi wonke amabheji amabi adayiswe.Ngokuhamba kwesikhathi, kusenamasethi amaningi wamadivayisi okulindeleke ukuthi afakwe ekukhiqizeni esikhathini esizayo.Kodwa-ke, ngaphansi kwesizinda esinjalo esingenathemba, okuhlanganisa ukususwa kwempahla encane ethekwini kanye nokwenyuka kwesikhathi eside kokusetshenziswa okuvela kuzinqubomgomo ezinkulu, kuzonikeza umfutho okhuphukayo we-ethylene glycol ecatshangwe kancane.Kusukela emiphumeleni, ukukhuphuka kwakamuva kwe-ethylene glycol kungcono kuneminye imikhiqizo ye-polyester.

 

1. Umthamo wokukhiqiza uthuthukiswa ngokwengeziwe, futhi amandla okuthuthukiswa kwamalahle ku-ethylene glycol makhulu.

Ngokwe-In deep Analysis of China's Ethylene Glycol Industry Development and Future Investment Research Report (2022-2029) ekhishwe yi-Guanyan Report Network, eminyakeni yamuva nje, imboni yomhlaba wonke ye-ethylene glycol ithuthuke ngokushesha, njengoba umthamo wokukhiqiza i-ethylene glycol kanye nomphumela ukhula unyaka. ngonyaka.Ngo-2021, amandla okukhiqiza i-ethylene glycol emhlabeni wonke azokhula ngo-19.4% unyaka nonyaka, futhi umphumela uzokhula ngo-7.5% unyaka nonyaka.Ngaphansi kwalesi sizinda, amandla okukhiqiza kanye nokuphuma kwemboni ye-ethylene glycol yaseChina nakho kuyanda unyaka nonyaka.

Mayelana namandla okukhiqiza, njengoba izwe linaka kakhulu imboni ye-ethylene glycol, isiqondiso esifanele kanye nezinqubomgomo ezisekelayo ezifana neFomula Yokukhuthaza Nokusebenzisa Ubuchwepheshe Nemikhiqizo Embonini Yamakhemikhali Nezamakhemikhali ngo-2021, Imibono Eyisiqondiso Ekuthuthukisweni. Ukuthuthukiswa Kwekhwalithi Ephezulu Yemboni Yamakhemikhali Nezamakhemikhali phakathi “noHlelo Lweminyaka Eyishumi Nane” kanye Nemibono Eqondisayo mayelana Nokuthuthukiswa Kwekhwalithi Ephezulu Yemboni Yezimboni Zemicu Yamakhemikhali ngo-2022 iyaqhubeka nokukhishwa, futhi isimo senqubomgomo yezimboni siyaqhubeka nokuba sihle, i-ethylene glycol yaseChina. amandla okukhiqiza akhula unyaka nonyaka.Ngokusho kwedatha, umthamo wokukhiqiza we-ethylene glycol waseChina uzokhuphuka usuka kumathani ayizigidi eziyi-8.32 uye kumathani ayizigidi ezingama-21.45 ukusuka ngo-2017 kuya ku-2021, ngesilinganiso sokukhula kwenhlanganisela yonyaka esingaba ngu-31%.

Ngokwezinga lokusetshenziswa kwamandla, izinga lokusebenzisa inani le-ethylene glycol e-China liphansi okwamanje, elalingaba ngu-68.63% ngo-2017;Izokwenyuka ifinyelele ku-73.42% ngo-2019. Kodwa-ke, kusukela ngo-2020 kuya ku-2021, ngenxa yomthelela wokuhlukaniswa nobhubhane ekhaya, ukugcinwa kwedivayisi ye-ethylene glycol, isilinganiso samandla kanye namanani aphezulu amalahle, umthwalo wokuqala we-ethylene glycol wasekhaya uphansi, futhi jikelele imboni iqala ukwehla kakhulu, okuholela ekutheni izinga lokusebenzisa umthamo we-ethylene glycol e-China lehle laya ku-60.06% kanye no-55.01% ngokulandelana eminyakeni emibili edlule.

Mayelana nokuphumayo, ngokwanda komthamo wemakethe ye-ethylene glycol kanye nokwanda okuphelele kwesidingo esingaphansi komfula, okukhiphayo nakho kukhombisa ukuthambekela kokukhula konyaka.Kusukela ngo-2017 kuya ku-2021, ukukhiqizwa kwe-ethylene glycol yaseChina kukhuphuke kusuka kumathani ayizigidi ezingu-5.71 kuya kumathani ayizigidi ezingu-11.8, futhi izinga lokukhula komkhiqizo walo liphinde labonisa umkhuba okhuphukayo eminyakeni emibili edlule, eqhutshwa ukukhula okukhulu kwamandla ayo okukhiqiza.Ngo-2021, izinga lokukhula kwe-ethylene glycol yaseChina lalicishe libe ngama-21.65% unyaka nonyaka, ngamaphesenti angama-2.63 ngaphezulu kwalelo lango-2020.

Kusukela ekushintsheni kwamandla okukhiqiza e-ethylene glycol eShayina, kuyabonakala ukuthi amandla okukhiqiza i-ethylene glycol aseShayina athuthuke nakakhulu eminyakeni emihlanu yakamuva, futhi imboni isesigabeni sokukhula nokuthuthuka.

Ngokwenqubo yemboni, kunezinqubo ezintathu zokukhiqiza ezijwayelekile ze-ethylene glycol e-China: ukuhlanganiswa (inqubo ye-naphtha/ethylene), i-MTO (i-methanol ku-olefin) namalahle ku-ethylene glycol.Njengamanje, ngenxa yobuchwepheshe obunekhono kakhulu be-petroleum kuya ku-ethylene glycol eShayina, okuwumzila wenqubo ojwayelekile, umthamo wokuklama we-petroleum kuya ku-ethylene glycol uba nenani eliphakeme kakhulu.Ngo-2021, umthamo wokukhiqiza we-petroleum ku-ethylene glycol e-China uzoba ngaphezu kuka-60%, futhi umphumela uzodlula amathani ayizigidi ezingu-7;Okwesibili ubuchwepheshe bamalahle kuya ku-ethylene glycol (umzila wamalahle owokusebenzisa igesi yokuhlanganisa amalahle kuqala, bese usebenzisa amanzi ne-carbon monoxide kugesi yokuhlanganisa njengezinto zokusetshenziswa ukulungisa i-ethylene glycol), amandla okukhiqiza abalwa ngaphezu kuka-30% kanye nomphumela ongaphezu kwamathani ayizigidi ezi-3.Intengo kawoyela ikhuphukile eminyakeni emibili yakamuva, futhi ukukhiqizwa kwamalahle ku-ethylene glycol eChina kukhule ngokushesha.Ngo-2021, ukukhiqizwa kwamalahle ku-ethylene glycol eChina kuzokhula cishe ngama-50% unyaka nonyaka.Njengoba iShayina inesakhiwo samandla “samalahle amaningi, igesi encane kanye nowoyela omncane”, amalahle aya ku-ethylene glycol yisici saseShayina mayelana nokuhlinzekwa okuphelele kwe-ethylene glycol eShayina.Esikhathini esizayo, amalahle aseShayina ku-ethylene glycol anamandla amakhulu okuthuthuka.
