Amanani emakethe yamakhemikhali aqhubekile ukwehla cishe isigamu sonyaka. Ukwehla okunjalo okude, ngenkathi amanani entengo kawoyela ahlala ephezulu, kuholele ekungalinganisweni ngenani lezixhumanisi eziningi embonini yezimboni zamakhemikhali. Ama-terminals amaningi ku-Industrial Chain, kulapho kucindezela ingcindezi ngezindleko zeketanga lezimboni. Ngakho-ke, imikhiqizo eminingi yamakhemikhali njengamanje isesimweni sezindleko eziphakeme kepha imakethe yabathengi evilaphayo, okuholela emnothweni wokukhiqiza ompofu wemikhiqizo eminingi yamakhemikhali.
Intengo yemakethe ye-vinyl acetate nayo iyaqhubeka nokuncipha. Eminyakeni yamuva nje, intengo yemakethe ye-vinyl acetate yehle ukusuka ku-14862 yuan / ithoni ngoJuni 2022 kuya kuJuni 2023, ngokuqhubekayo iyehla cishe unyaka, ngentengo ephansi kakhulu yehla ku-5990 yuan / ton. Ukusuka kumanani entengo yeminyaka embalwa edlule, intengo ephansi emlandweni ivele ngo-Ephreli 2020, inani eliphansi kakhulu livele ku-5115 yuan / ton, inani eliphakeme kakhulu livele ngo-Novemba 2021, kanti inani eliphakeme kakhulu livele ngo-16727 yuan / ton.

Yize intengo ye-vinyl acetate ibilokhu incipha unyaka olandelanayo, inzuzo yokukhiqiza ye-vinyl acetate ihlala iphakeme futhi umnotho wokukhiqiza muhle. Kungani uVinyl Acetate Gcina izinga eliphakeme lokuchuma?
Izinqubo ezahlukahlukene zokukhiqiza ze-Vinyl Acetate zivela enzuzo nasekulahlekelweni okuhlukahlukene
Ngokokuguqulwa kwezinga lenzuzo ye-vinyl acetate ekhiqizwa yindlela ye-ethylene, izinga lenzuzo ye-vinyl acetate ekhiqizwa yindlela ye-ethylene ibilokhu isesimweni senzuzo eminyakeni embalwa edlule, inani lenzuzo eliphakeme kakhulu lifinyelele kuma-50% noma ngaphezulu, Futhi isilinganiso senzuzo esejwayelekile singaba ngu-15%. Kungabonakala ukuthi i-vinyline acetate esekelwe e-vinyl ibe ngumkhiqizo onenzuzo enkulu eminyakeni emibili edlule, ngokuchuma okuhle okuphelele kanye nemishado yenzuzo ezinzile.

Ngokombono we-calcium carbide indlela vinyl acetate, eminyakeni emibili edlule, ngaphandle kwenzuzo enkulu evela ngoJulayi 2022 kuya kuJulayi 2022, zonke ezinye izikhathi ziye zisesimweni sokulahleka. Kusukela ngoJuni 2023, izinga lenzuzo yenzuzo ye-calcium carbide acetate ecishe ibe ngu-20%, kanye nomugqa wenzuzo wenzuzo ye-calcium carbide indlela vinyl acetate kule minyaka emibili edlule kwakungu-0.2% ukulahleka. Kungabonakala ukuthi ukuchuma kwendlela ye-calcium carbide ye-vinyl acetate kubi, futhi isimo sonke sibonisa ukulahleka.

Kungabonakala ukuthi akuyona into evamile ye-vinyl acetate ukuze ibe sezingeni lenzuzo ephezulu. Indlela ye-ethylene kuphela yokukhiqizwa kwe-vinyl acetate okwamanje isesimweni senzuzo, kuyilapho indlela ye-carbide ibilokhu ilahlekelwe yisimo sendawo yokulahleka eminyakeni embalwa edlule.
Ukuhlaziywa kokugcina inzuzo ephezulu ye-EthLyene Acetate Production
1. Ingxenye yezindleko ezibonakalayo ezingavuthiwe ziyahlukahluka ngezinqubo ezahlukahlukene zokukhiqiza. Ku-Ethylene based vinyl acetate Production, ukusetshenziswa kweyunithi kwe-ethylene kungu-0.35 kanye nokusetshenziswa kweyunithi ye-glacial acetic acid ngu-0.72. Ngokwezinga lentengo elijwayelekile ngoJuni 2023, inani le-Ethylene e-Ethylene actetate Production imayelana nama-37%, kanti i-glacial acetic acid ingama-45%. Ngakho-ke, ukuguquguquka kwentengo kwe-glacial acetic acid kunomthelela omkhulu kakhulu ekushintsheni kwezindleko ze-Ethylene Acetate Production, kulandelwe yi-Ethylene.
Ngokuqondene nezindleko ze-calcium carbide indlela ye-vinyl acetate, ama-47% ezindleko ze-calcium carbide indlela ye-vinyl acetate acetate, kanye ne-accounce acetic acid account cishe ama-35% wezindleko ze-calcium carbide indlela ye-vinyl acetate. Ngakho-ke, ngendlela ye-calcium carbide ye-vinyl acetate, ushintsho ngentengo ye-calcium carbide inomthelela omkhulu kwizindleko, ezihluke kakhulu emthonjeni wezindleko zendlela ye-ethylene.
2. Ukwehla okubalulekile kwezinto ezingavuthiwe ethylene kanye ne-glacial acetic acid kuholele ekunciphiseni okukhulu kwezindleko. Ngokusho kwemininingwane efanelekile, ngonyaka owedlule, intengo kaCfr eNorthast Asia Ethylene yehle ngo-33%, futhi intengo ye-glacial acetic acid yehle nge-32%. Kodwa-ke, izindleko zokukhiqiza ze-Vinyl Acetate zisebenzisa indlela yeCalcium Carbide zikhawulelwe yintengo ye-calcium carbide. Ngonyaka owedlule, intengo ye-calcium carbide yehle ngo-25%.
Ngakho-ke, ngokombono wezinqubo ezimbili ezihlukene zokukhiqiza, izindleko ezibonakalayo ezibonakalayo zendlela ye-Ethylene Acetate ye-Ethyl zinciphile kakhulu, futhi ukuncishiswa kwezindleko kukhulu kunaleyo ye-calcium carbide indlela.

3. Yize intengo ye-vinyl acetate yehle, ukwehla akubalulekile njengamanye amakhemikhali. Ngonyaka owedlule, intengo ye-vinyl acetate yehle ngo-59%, okubonakala sengathi yinto ebalulekile, kepha intengo yamanye amakhemikhali inwehlile kakhulu.
I-Vinyl Acetate ibilokhu igcina i-margin ethile yenzuzo, ikakhulukazi ngenxa yokuncishiswa kwezindleko okubangelwa ukwehla kwamanani entengo eluhlaza, kunokusekelwa kwemakethe yabathengi ngamanani ayo. Lesi futhi isimo samanje sokudluliselwa kwenani ekhasini le-Vinyl Acetate Imboni. Kusuka esimweni samanje semakethe yamakhemikhali yamakhemikhali yaseChina ngesikhathi esifushane, kunzima ukuguqula isimo esibuthakathaka emakethe yamakhemikhali amaShayina ngaphandle kwezinqubomgomo ezinkulu zokuvuselela amakethe. Kulindelwe ukuthi i-value chain ye-vinyl acetate izoqhubeka nokugcina i-logic yokudlulisa phansi, futhi kulindeleke ukuthi inzuzo yokukhiqiza emakethe ye-polyethylene kanye nemikhiqizo ye-eV, izogcinwa ngokunciphisa inzuzo ye-vinyl acetate.
