Ukunikezwa okuphelele kwe-glaciali-acetic acidimakethe ngo-Agasti iphezulu, futhi enye engezansi komfula ikwisizini engasebenzi, ngakho-ke isidingo se-acetic acid singakhawulwa. Njengoba kunamabhizinisi ambalwa alungisa kabusha kule nyanga, yi-Shanghai Huayi kanye no-Dalian Hengli kuphela abanezinhlelo zokulungisa kabusha, ukunikezwa kuhlala kuphezulu, futhi i-inventory yefekthri isezingeni eliphakathi nendawo eliphezulu. Kunzima ukusekela ukwenyuka kwentengo ngoba kunezici eziningi ezingezinhle emakethe yesikhathi esifushane ye-glacial acetic acid.

Eminyakeni yakamuva, umthamo wokukhiqiza we-glacial acetic acid kanye nezimboni zayo eziyinhloko ezansi nomfula ubonise umkhuba okhulayo. Nokho, ukudluliswa kwenzuzo ochungechungeni lwemboni akulingani. Ngokuzayo, izohlala ingenye yezinto ezihamba phambili zenzuzo nokunwetshwa kwesidingo. Amandla okunikezwa kwe-glacial acetic acid nakanjani azokhuphuka kakhulu. Ngaleso sikhathi, ibhalansi phakathi kokunikezwa kanye nesidingo izophulwa.

Nakuba amandla okukhiqiza i-acetic acid ecwebezelayo ekhula kancane kancane, ukusetshenziswa nakho kubonisa inkambiso yokukhula, kodwa ukudluliswa kwenzuzo ochungechungeni lwemboni akulingani, futhi isimo senzuzo kwezinye izindawo ezingezansi ngeke kushiwo ukuthi silungile.

Amandla okukhiqiza i-acetic acid e-glacial ayanda kancane kancane

Phakathi kuka-2018-2022, umthamo wokukhiqiza i-acetic acid e-glacial e-China anda kancane kancane, esekelwa ukuthuthukiswa kwesidingo esiphansi kanye nenzuzo enhle. Kusukela ngo-2022, umthamo wonyaka osebenzayo we-glacial acetic acid ungamathani ayizigidi eziyi-10.46, akhuphuke ngo-18 t.86% kusukela ngo-2018.

Kule minyaka emihlanu edlule, intengo iyonke ye-glacial acetic acid ibilokhu ikhuphuka, isekelwa ukwanda kwesidingo sasekhaya kanye nemakethe esebenzayo yokuthekelisa. Ngesikhathi esifanayo, igcine umehluko omkhulu wamanani nge-methanol yempahla eluhlaza isikhathi esiningi, okuholela enzuzweni eqinile kanye nesikhathi eside senzuzo.

Ngo-2017-2018, isitshalo se-glacial acetic acid sangaphandle siqala singazinzile, futhi imakethe yokuthekelisa yanikeza ukwesekwa kwemakethe yasekhaya. Ngaphezu kwalokho, ngokuncipha komthamo wasekhaya we-glacial acetic acid kanye nokwanda komthamo womfula, isidingo se-glacial acetic acid sisanda kunyuka, okuhlangene kwasekela ukwenyuka kwamanani entengo ye-glacial acetic acid. Nakuba ukuthambekela ngokuyisisekelo kufana naleyo ye-methanol yezinto ezingavuthiwe, umehluko wamanani ulokhu ukhula futhi nenzuzo yenzuzo iyakhula. ngo-2018, isilinganiso senzuzo eyisamba setiyetha emakethe ye-China esempumalanga sasilinganiselwa ku-1,753 yuan/ton. ngo-2019-2020, umthamo wokukhiqiza we-glacial acetic acid wasekhaya ukhuphuka kancane futhi ukunikezwa kuyanda. Isidingo siyehla ngezigaba ngenxa yezinto ezingalindelekile. Izintengo zasekhaya ze-glacial acetic acid ziyaguquguquka, futhi umehluko wentengo nge-methanol wehla ngezinga elithile. ngo-2020, isilinganiso senzuzo eyisamba setiyetha emakethe ye-China esempumalanga cishe singama-yuan angama-504/ton. ngo-2021, nakuba zombili izintengo ze-methanol ne-glacial acetic acid zikhuphuka, intengo ye-glacial acetic acid ikhuphuka kakhulu ngenxa yokwenyuka kwesidingo sasekhaya nesangaphandle kanye nokwehla ngezigaba kokunikezwayo, okwenza umehluko wamanani phakathi kwakho kokubili uqhubeke nokukhula. Isilinganiso saminyaka yonke semaliji ephelele emakethe yase-East China sasilinganiselwa ku-RMB399/ton.41%.

Nakuba inzuzo yayinkulu kakhulu, isidingo esiphansi somfula sibonise ukukhula okuqhubekayo, okwenza abakhiqizi abakhona kanye nabadlali abasha bemakethe bathuthukise izinhlelo ezintsha zephrojekthi ye-glacial acetic acid, iningi lazo eliphinde laqaliswa.

Isidingo sesikhathi esizayo esingezansi sisakhula

Kusenezinhlelo zomthamo omusha wemikhiqizo eminingi ezansi nomfula esikhathini esizayo, okuqhubekisela phambili ukukhula komthamo we-glacial acetic acid.

Kusukela ngo-2021 kuya ku-2022, umthamo wokukhiqiza we-EVA ukhula ngokushesha futhi imikhiqizo nayo isondela ekukhuleni okuphezulu kokuqukethwe kwe-VA vinyl acetate, nokwanda okukhulu kwesidingo se-vinyl acetate, ukunwetshwa komthamo wokukhiqiza we-vinyl acetate, kanye nokushoda okuvelele kokutholakala kwe-non-calcium carbide. Kusukela ngo-2022, okunye ukuhlinzekwa kwe-calcium carbide kuye kwanezelwa kubasebenzisi bokuqala bokuhlinzeka nge-ethylene, iphethini yase-China ye-ethylene acetate ishintshile isuka ensaleni yesakhiwo yaba ukungezwani kwesakhiwo. I-EVA icubungula i-ethylene acetate yokuzakhela yona ngenxa yobunzima obukhulayo kanye nezindleko zokuthenga ngabasebenzisi. Kuze kube yileso sikhathi, inqwaba yamaphrojekthi asakhiwa ayaqhubeka futhi umthamo wokukhiqiza we-ethylene vinyl acetate uzokhishwa ngo-2023.

I-Ethyl acetate futhi ingenye yemikhiqizo emikhulu ephansi yomfula we-glacial acetic acid. Eminyakeni yamuva nje, ukungqubuzana phakathi kokunikezwa kanye nesidingo se-ethyl acetate bekugqamile, futhi izinga lokukhula komthamo lihamba kancane. 2022-2023, amandla amasha asatholakala ikakhulukazi ezinkampanini ezikhona, ikakhulukazi ukwandisa isabelo semboni, ukunciphisa izindleko nokuthuthukisa ukusebenza kahle. Ngaphezu kwalokho, ngokuthambekela kwamanje kokuhlanganiswa embonini ye-petrochemical ngokuya ngokusobala, ezinye izinkampani zihlela ukwakha izitshalo ezintsha ze-ethyl acetate ukuze zandise uchungechunge lwezimboni. Kodwa-ke, ngenxa yenqubo elula yokukhiqiza ye-ethyl acetate, ukushintsha okusheshayo kwemishini yasekhaya kanye nokukhiqizwa okuvumelana nezimo, ikakhulukazi ngokusekelwe ezindlekweni nezinguquko zesidingo, izinga lokukhula komkhiqizo lihamba kancane eminyakeni yamuva.

Mayelana ne-acetic anhydride, eminyakeni yamuva nje, amathuluzi amasha kanye nemishini engasasebenzi kuhlangene, futhi ukunikezwa sekukonke kubonisa inkambiso yokukhula. Ngokombono wesakhiwo sokusetshenziswa, isetshenziswa kakhulu ekukhiqizeni i-acetate fiber, i-intermediate yemithi, izibulala-zinambuzane, izinongo, odayi, izithasiselo zokudla, ama-chemical dehydration agents kanye neminye imikhakha. Ezinye izitshalo zasekhaya ze-acetic fiber zifakwe izitshalo ze-acetic anhydride, futhi ukuhlanganiswa kwezinye izinkambu akuphakeme. Ngokuzayo, izitshalo ze-acetic anhydride zisazokwakhiwa. UNingxia Donghe uhlela ukufaka amathani ayi-150,000 engxenyeni yesibili yalo nyaka. UHenan Ruibai uhlela nokwakha isitshalo esisha se-acetic anhydride, futhi amandla okukhiqiza embonini kulindeleke ukuthi aqhubeke nokukhula. I-acetic anhydride inezinhlobonhlobo zezindawo ezansi nomfula futhi sisekhona indawo yokukhula ohlangothini lwesidingo, kodwa ngokwanda komthamo wokukhiqiza, imboni izoncintisana ngokwandayo.

Amaphrojekthi amaningi amasha e-glacial acetic acid esikhathini esizayo, ibhalansi yokunikezwa kanye nesidingo ingase yephulwe
Ukusebenza kwenzuzo okungcono kakhulu eminyakeni yamuva nje, kanye nokwenyuka okuqhubekayo kwesidingo esiphansi somfula, kwenza ukutholakala kwe-acetic acid ecwebezelayo nakho kuqhubeke kudlondlobala, kanti neminyaka emithathu ezayo injalo.

Ithebula elingenhla libonisa ezinye zezinhlelo ezintsha zamandla e-glacial acetic acid eminyakeni emithathu ezayo, ngaphezu kwezinye izinkampani futhi zinezinhlelo ezintsha zokwakha nokwandisa, kungabonakala ukuthi ukukhula kwamandla okuzayo kwe-glacial acetic acid kusalindeleke ukuthi kube kukhulu uma kuqhathaniswa. Nakuba isidingo esingezansi komfula sizophinde sibe nokunyuka okuqhubekayo, kodwa ukuthi ingakwazi yini ukumunca ngokuphelele ukunikezwa kwe-acetic acid ekhuphukayo kusazobhekwa futhi, futhi ngeke kukhishwe ukuthi i-glacial acetic acid e-China izoba namandla ngokweqile.
