Unikezelo jikelele lwe-glacialiacetic acidimarike ngo-Agasti iphezulu, kwaye ezinye ezantsi kukwi-off-season, ngoko imfuno ye-acetic acid inokulinganiselwa.Njengoko kukho amashishini amancinci okulungisa kule nyanga, yiShailand Huayi kunye noDalian Hengli kuphela abanezicwangciso zokulungisa, unikezelo luhlala luphezulu, kwaye i-inventory yefektri ikwizinga eliphakathi.Kunzima ukuxhasa ukunyuka kwexabiso kuba kukho iinkalo ezininzi ezimbi kwimarike ye-glacial acetic acid yexesha elifutshane.

Kwiminyaka yakutshanje, amandla okuvelisa i-glacial acetic acid kunye namashishini ayo asezantsi abonise ukukhula.Nangona kunjalo, ukuhanjiswa kwengeniso kwikhonkco loshishino akulingani.Kwixesha elizayo, iya kuhlala ingomnye wabaqhubi benzuzo kunye nokwandiswa kwemfuno.Umthamo wokubonelela nge-glacial acetic acid unyanzelekile ukuba unyuke ngakumbi.Ngelo xesha, ibhalansi phakathi kokubonelela kunye nemfuno iya kwaphulwa.

Nangona umthamo we-acetic acid we-glacial ukhula ngokuthe ngcembe, ukusetyenziswa kukwabonisa ukukhula, kodwa ukuhanjiswa kwengeniso kwikhonkco loshishino akulingani, kwaye imeko yenzuzo kwezinye iindawo ezisezantsi ayinakuthiwa ilungile.

Umthamo wokuvelisa i-acetic acid yeglacial uyanda ngokuthe ngcembe

Ngexesha le-2018-2022, umthamo wokuvelisa i-acetic acid e-China yanda ngokuthe ngcembe, ixhaswa kuphuhliso lwemfuno esezantsi kunye nenzuzo enhle.Ukusukela ngo-2022, umthamo wonyaka osebenzayo we-glacial acetic acid yi-10.46 yezigidi zeetoni, ukuya kwi-18 t.86% ukusuka kwi-2018.

Kule minyaka mihlanu idlulileyo, ixabiso lilonke le-acetic acid belikwindlela enyukayo, lixhaswa kukonyuka kwemfuno yangaphakathi kunye nemarike esebenzayo yokuthumela ngaphandle.Kwangaxeshanye, iye yagcina umahluko omkhulu wamaxabiso ngemethanol ekrwada ixesha elininzi, okukhokelela kwingeniso eyomeleleyo kunye nexesha elide lenzuzo.

Ngo-2017-2018, isityalo sangaphandle se-acetic acid siqala ngokungazinzanga, kwaye imarike yokuthumela ngaphandle ibonelele ngenkxaso kwimarike yasekhaya.Ukongeza, ngokucotha komthamo we-acetic acid yasekhaya kunye nokwandiswa komthamo osezantsi, imfuno ye-acetic acid yomkhenkce isandula ukwanda, ethe xa idibene yaxhasa ukunyuka kwamaxabiso asekhaya e-acetic acid.Nangona imeko iyafana naleyo yemethanol ekrwada, umahluko wexabiso uqhubeka usanda kwaye nomda wenzuzo uyakhula.ngo 2018, i-avareji theory inzuzo gross kwimarike yasempuma China malunga 1,753 yuan/ton.ngo-2019-2020, umthamo wemveliso ye-acetic acid yasekhaya iyenyuka ngokuthe chu kwaye unikezelo luyanda.Imfuno iyehla ngezigaba ngenxa yezinto ebezingalindelekanga.Amaxabiso e-acetic acid yasekhaya ayaguquguquka, kwaye umahluko wexabiso kunye nemethanol uyehla ukusa kwinqanaba elithile.ngo-2020, i-avareji yengeniso yethiyori kwimarike yasempuma China imalunga ne-504 yuan/ton.ngo-2021, nangona omabini amaxabiso e-methanol kunye ne-glacial acetic acid ekwindlela enyukayo, ixabiso le-glacial acetic acid linyuka ngakumbi ngenxa yokunyuka kwemfuno yasekhaya neyangaphandle kunye nokwehla ngezigaba konikezelo, okwenza umahluko wamaxabiso phakathi kwezi zimbini uqhubeke andisa.Umyinge wonyaka we-gross margin kwimarike yase-East China yayimalunga ne-RMB399/ton.41%.

Nangona inzuzo yayininzi kakhulu, imfuno esezantsi yomlambo ibonise ukukhula okuqhubekayo, okubangela ukuba abavelisi abakhoyo kunye nabadlali abatsha bemarike baphuhlise izicwangciso zeprojekthi ye-glacial acetic acid, uninzi lwazo lwaphunyezwa.

Imfuno esezantsi yomlambo isakhula

Kusekho izicwangciso zomthamo omtsha kwiimveliso ezininzi ezisezantsi kwikamva, ukuqhuba ukukhula okuqhubekayo kwi-glacial acetic acid umthamo wokubonelela.

Ukusukela ngo-2021 ukuya ku-2022, amandla okuvelisa i-EVA akhula ngokukhawuleza kwaye iimveliso nazo zisondela ekukhuleni okuphezulu komxholo we-VA vinyl acetate, kunye nokwanda okukhulu kwemfuno ye-vinyl acetate, ukwandiswa komthamo wokuvelisa i-vinyl acetate, kunye nokunqongophala okubalaseleyo konikezelo lwe-calcium carbide.Ukusukela ngo-2022, unikezelo lwe-calcium carbide luye longezwa kubasebenzisi bokuqala bobonelelo lwe-ethylene, ipateni yobonelelo lwe-ethylene acetate yaseTshayina itshintshile ukusuka kwintsalela yesakhiwo ukuya kuxinzelelo lolwakhiwo.I-EVA icinga ngokuzakhela i-ethylene acetate ngenxa yobunzima obuninzi kunye neendleko zokuthenga ngabasebenzisi.Kude kube lelo xesha, inani leeprojekthi ezisakhiwayo ziyaqhubeka kwaye umthamo we-ethylene vinyl acetate uza kukhutshwa ngo-2023.

I-Ethyl acetate yenye yeemveliso eziphambili ze-acetic acid.Kwiminyaka yakutshanje, ukuchasana phakathi kokubonelela kunye nemfuno ye-ethyl acetate kuye kwabonakala, kwaye izinga lokukhula komthamo lihamba kancinci.Ngo-2022-2023, amandla amatsha asafumaneka ikakhulu kwiinkampani ezikhoyo, ubukhulu becala ukwandisa isabelo seshishini, ukunciphisa ngakumbi iindleko kunye nokuphucula ukusebenza kakuhle.Ukongeza, kunye nendlela yangoku yokudityaniswa kwishishini lepetrochemical libonakala ngakumbi nangakumbi, ezinye iinkampani ziceba ukwakha izityalo ezitsha ze-ethyl acetate ukwandisa ikhonkco leshishini.Nangona kunjalo, ngenxa yenkqubo elula yokuvelisa i-ethyl acetate, utshintsho olukhawulezayo lwezixhobo zasekhaya kunye nemveliso eguquguqukayo, ikakhulu ngokusekelwe kwiindleko kunye neenguqu zemfuno, izinga lokukhula kwemveliso liye lacotha kwiminyaka yamuva.

Ngokumalunga ne-acetic anhydride, kwiminyaka yakutshanje, izixhobo ezitsha kunye nezixhobo eziphelelwe yisikhathi zikhona, kwaye ukunikezelwa ngokubanzi kubonisa ukukhula.Ngokombono wesakhiwo sokusetyenziswa, isetyenziswa kakhulu kwimveliso ye-acetate fiber, i-pharmaceutical intermediates, i-pesticide intermediates, iziqholo, idayi, izongezo zokutya, i-agent dehydration agents kunye nezinye iindawo.Ezinye izityalo zasekhaya ze-acetic fiber zixhotyiswe ngezityalo ze-acetic anhydride, kwaye ukudibanisa kwamanye amasimi akuphezulu.Kwixesha elizayo, izityalo ze-acetic anhydride ziya kuba zisakhiwa.UNingxia Donghe uceba ukubeka iitoni ze-150,000 ekusebenzeni kwisiqingatha sesibini salo nyaka.U-Henan Ruibai uphinde uceba ukwakha isityalo esitsha se-acetic anhydride, kwaye umthamo wemveliso yeshishini kulindeleke ukuba uqhubeke nokwandisa.I-acetic anhydride inoluhlu olubanzi lweendawo ezisezantsi kwaye kusekho indawo yokukhula kwicala lemfuno, kodwa ngokunyuka kwamandla okuvelisa, ishishini liya kukhuphisana ngakumbi.

Iiprojekthi ezininzi ezintsha ze-glacial acetic acid kwixesha elizayo, ibhalansi yokubonelela kunye nemfuno inokophulwa
Ukusebenza kwengeniso engcono kwiminyaka yakutshanje, kunye nokunyuka okuqhubekayo kwimfuno ephantsi, yenza unikezelo lwe-acetic acid ye-glacial luhlala lukhula ngokukhawuleza, kwaye iminyaka emithathu ezayo ayifani.

Le theyibhile ingentla ibonisa ezinye zezicwangciso ezintsha ze-glacial acetic acid kule minyaka mithathu izayo, ukongeza kwezinye iinkampani zinezicwangciso ezintsha zokwakha kunye nolwandiso, kunokubonwa ukuba ukukhula komthamo we-acetic kwixa elizayo kusalindeleke ukuba kulingane. enkulu.Nangona imfuno esezantsi yomlambo nayo iya kuba nokunyuka okuqhubekayo, kodwa ingaba inokufunxa ngokupheleleyo unikezelo lwe-acetic acid eyongeziweyo yomkhenkce isaza kujongwa ngakumbi, kwaye ayinakukhutshelwa ngaphandle ukuba i-acetic acid yomkhenkce e-China iya kuba nomthamo ogqithisileyo.
