I-Acetic Acid – igama lamakhemikhali elizwakala limuncu kancane – empeleni “liyigazi” elibalulekile embonini yanamuhla. Akuyona nje kuphela umthombo wokunambitheka kuviniga wasekhishini kodwa futhi liyisisekelo esisekela izimboni zezindwangu, zepulasitiki, zemithi, ngisho nezimboni zamabhethri amasha.
Kulesi sihloko, sizohlola isikhathi esidlule nesamanje se-acetic acid, sihlaziye ukuguquguquka kwemakethe kwakamuva ngo-2026 - ikakhulukazi ukuthi amanani e-acetic acid akhuphuke kanjani ngo-80% ezinyangeni ezimbili nje - bese siphendula imibuzo yakho sisebenzisa ifomethi ye-Q&A.
Ingxenye 1: Ukuhlangana Kokuqala Ne-Acetic Acid – Okungaphezu Kokuthi “Kumuncu”
I-Acetic Acid, enefomula yamakhemikhali i-CH₃COOH, iyinhlanganisela eyisisekelo. Uma uhlangana nayo elebhu, qaphela: i-acetic acid emsulwa iyaqina ibe amakristalu afana neqhwa ngaphansi kuka-16.6°C, okwenza ibizwe ngokuthi “i-Glacial Acetic Acid.”
Empilweni yansuku zonke, sihlangana ne-acetic acid ekuhlungeni okungu-3-5% - okungukuthi, uviniga wetafula. Kodwa emkhakheni wezimboni, i-acetic acid ingumdlali oguquguqukayo onezindima ezibalulekile:
Isinyibilikisi se-PTA (i-Purified Terephthalic Acid): Lesi yisona sidakamizwa esikhulu kunazo zonke se-acetic acid, esibalelwa cishe ingxenye yesine yokusetshenziswa kwayo konke, esisetshenziswa ekukhiqizeni imicu yezingubo namabhodlela eziphuzo.
Izinto Ezingavuthiwe ze-VAM (i-Vinyl Acetate Monomer): Zisetshenziselwa ukukhiqiza amafilimu okunamathela e-photovoltaic, upende, kanye nokunamathela.
Ukudla Nemithi: Njenge-acidulent noma into ebalulekile yokwenza i-Aspirin.
Q: Ingabe i-Glacial Acetic Acid “ibanda kakhulu” ngempela?
A: Empeleni, akuphathelene nokushisa okuphansi, kodwa izinga layo eliphezulu lokuncibilika (16.6°C). Ezindaweni eziseningizimu ezingashisi ngesikhathi sasebusika, ibhodlela lonke le-acetic acid ehlanzekile kakhulu lingaqina libe yisigaxa esifana ne-ice cube enkulu, yingakho libizwa ngokuthi “i-Glacial Acetic Acid.”
Ingxenye 2: I-News Flash – “Ukwanda Okungazelelwe” kwe-Acetic Acid ka-2026
Uma ufuna ukwazi okwakamuva embonini ye-acetic acid, igama elingukhiye lithi: “Ukunyuka Kwentengo.”
Kusukela ngoMashi 2026, imakethe ye-acetic acid yasekhaya iqale ukuthambekela okunamandla ngokumangalisayo. Ngokusho kombiko wocwaningo oluvela ku-Guosen Securities, kusukela ngomhlaka-13 Ephreli 2026, intengo ejwayelekile ye-acetic acid emakethe yaseJiangsu yayifinyelele ku-4,500 RMB/ton. Kusho ukuthini lokhu? Kusukela ekuqaleni kukaMashi, amanani e-acetic acid ayezungeze u-2,500 RMB/ton.
Ngenyanga eyodwa nesigamu nje kuphela, ukwanda kufinyelele ku-80% omangalisayo!

Kungani ukwanda okukhulu?
Ngemuva kwalokhu kukhona “isiphepho esiphelele” ochungechungeni lokuhlinzekwa komhlaba wonke:
Ukusheshisa Izindleko: Izinto zokusetshenziswa ezikhuphukayo ze-acetic acid yi-methanol. Ngo-2026, ezithintwe yizingxabano zezepolitiki eMpumalanga Ephakathi, amanani e-methanol, izinto zokusetshenziswa eziyinhloko ze-acetic acid, akhuphuke ngo-50%, okwenza izindleko zokukhiqiza i-acetic acid zikhuphuke ngqo.
Ukuncishiswa Kokukhiqiza Kwamanye Amazwe: Ngenxa yamanani aphezulu egesi yemvelo eYurophu nase-US, izimboni ze-acetic acid zaphesheya kwezilwandle (isb., i-Celanese) bezilokhu zinciphisa amazinga okusebenza, okudala igebe elikhulu ekuhlinzekweni kwe-acetic acid emhlabeni jikelele.
Ukudonswa Kwempahla Ethunyelwa Ngaphandle: Bebhekene nokuntuleka kwamanye amazwe, abathengi baphendukela eShayina. Ku-Q1 2026, ama-oda okuthumela ngaphandle kwe-acetic acid yaseShayina aqhuma kakhulu, okuqinisa kakhulu ukutholakala kwe-acetic acid emakethe yasekhaya.
Q: Ingabe kusesephuze kakhulu ukutshala imali ekwakheni isitshalo se-acetic acid manje?
A: Lokho kudinga ukubheka izinhlangothi ezimbili. Esikhathini esifushane, i-acetic acid ngempela inenzuzo enkulu. Kodwa-ke, ngokuhamba kwesikhathi, izinkampani ezinkulu zezimboni sezivele zisesimweni esihle. NgoJanuwari 2026, iphrojekthi ye-acetic acid kaJuzhengyuan engamathani ayizigidi ezingu-1.5 ngonyaka eJieyang yaqala ukukhiqizwa - enye yamayunithi amakhulu kakhulu e-acetic acid emhlabeni. Njengoba la mandla amasha e-acetic acid efika ku-inthanethi ngonyaka olandelayo noma emibili, imakethe ingaphinde ingene esimweni esilinganiselayo noma esinikezwe ngokweqile.
Ingxenye 3: Izitayela Zemboni - Likuphi Ithuba Elikhulu Elilandelayo Le-Acetic Acid?
Liyaphi ikusasa lemboni ye-acetic acid? Sihlaziya ngezindlela ezintathu: ubuchwepheshe, isidingo, kanye nesifunda.
1. Intuthuko Kwezobuchwepheshe Basekhaya
Ngaphambilini, ukukhiqiza i-acetic acid kwakuncike kakhulu ekungeniseni amalungelo obunikazi obuchwepheshe bangaphandle. Manje, iShayina ayigcinanga nje ngobuchwepheshe obuyinhloko kodwa iyaqhubeka nokubenza ngcono. Ubuchwepheshe basekhaya be-carbonylation obusebenzisa umfutho ophansi obusetshenziswa kuphrojekthi yeJuzhengyuan bunezinga eliphezulu lokuguqulwa kanye nokusetshenziswa kwamandla okuncishisiwe kakhulu. Lokhu kusho ukuthi ukukhiqizwa kwe-acetic acid esikhathini esizayo kuzoba luhlaza futhi kube nezindleko eziphansi.
2. Isidingo Esihlukahlukene Esiphansi
I-Acetic acid ayiseyona nje "ikhemikhali yezimpahla"; ihlanganisa ubuchwepheshe obuphezulu:
Imboni ye-Photovoltaic: Isidingo samafilimu e-PV senza ukusetshenziswa kwe-acetic acid (VAM) kukhuphuke.
Amabhethri Amasha Amandla: I-Acetic acid iyisici esibalulekile kwezinye izinyibilikisi zebhethri ezisebenza kahle kakhulu kanye nama-electrolyte.
3. Ukuvuka Kwesifunda KweNingizimu China
Ngaphambilini, amandla okukhiqiza i-acetic acid ayegxile ezindaweni zamakhemikhali zamalahle njenge-East China ne-Shandong. Ngenxa yokuntuleka kwezinto zokusetshenziswa eziphezulu, iNingizimu China yayiyindawo esetshenziswa kahle i-acetic acid. Ngokuqaliswa kwephrojekthi ye-Jieyang, iphethini yokuhlinzekwa kwe-acetic acid eNingizimu China iye yaphazamiseka. Amabhizinisi angaphansi komhlaba anganciphisa kakhulu izindleko zezokuthutha futhi afinyelele uchungechunge lwezimboni oluvaliwe.
Ingxenye 4: Imibuzo Nezimpendulo Zokucwila Ngokujulile – Amaqiniso Abalulekile Okufanele Uwazi Nge-Acetic Acid
Ukuze sikusize uqonde i-acetic acid kabanzi, sihlanganise le mibuzo evame ukubuzwa:
Umbuzo 1: Ingabe i-acetic acid iyikhemikhali eyingozi?
A: Yebo. I-glacial acetic acid iyalimaza futhi iyacasula. Umhwamuko wayo uyacasula kakhulu amehlo nekhala, futhi iyasha (iphuzu lokukhanya elingu-39°C). Ezimbonini, ukuthutha i-acetic acid kudinga amaloli ethangi lensimbi engagqwali. Ukuze uthintane nsuku zonke, gqoka amagilavu amelana ne-acid-alkali kanye nezibuko zokuphepha.
Umbuzo 2: Ngaphandle kokusetshenziswa kwezimboni, yiziphi ezinye izindlela eziwusizo zokusebenzisa i-acetic acid ekhaya?
A: Ziningi! Ngoba i-acetic acid ine-asidi encane futhi inezakhiwo zokubulala amagciwane:
Ukususa usayizi: Isixazululo se-acetic acid esixutshiwe sisusa kalula i-limescale emaketeleni.
Ukuhlanza Okukhanyayo: Ukwengeza amaconsi ambalwa e-acetic acid exutshwe emshinini wokuhlanza izingubo ezimnyama kuqeda insipho ye-alkaline esele, okwenza imibala ikhanye kakhulu. Lesi simiso sisetshenziswa ezithambisweni eziningi zendwangu.
Ukubulala amagciwane: I-Acetic acid iyi-antiseptic yemvelo; ukukha imifino eqoshiwe kusebenzisa lesi sici.
UMBUZO 3: Ingabe amanani e-acetic acid azoqhubeka nokwenyuka engxenyeni yesibili ka-2026?
A: Imboni ivumelana ngokuthi amanani azohlala ephezulu kodwa ngenzuzo encane. Esikhathini esifushane, ngenxa yokulungiswa okuhleliwe kwezitshalo eziningi ze-acetic acid emhlabeni jikelele ngo-Ephreli nangoMeyi, ukutholakala kuzohlala kuncane. Kodwa-ke, ngokuhamba kwesikhathi, njengoba umthamo omusha we-acetic acid ufika kancane kancane, amanani cishe azobuyela emuva kusukela ekuphakameni kwawo aye ebangeni elifanele (cishe ama-RMB angu-3,000-3,500/ton).
Isiphetho
Kusukela esitsheni esilula seviniga ekhishini kuya ezintweni zamakhemikhali ezisekela izimboni ezinkulu zezwe, i-acetic acid, nakuba incane, ithinta kakhulu umnotho wezwe kanye nezindlela zokuphila zabantu. Isiphepho sika-2026 samanani e-acetic acid siwumphumela wezepolitiki kanye nethuba lomkhakha wokukhiqiza waseShayina lokushintshela ekuthuthukisweni okuluhlaza okwesiphezulu. Kumabhizinisi, kuphela ngokuqonda ukuguquguquka kwe-acetic acid lapho bengathola khona “indawo emnandi” “ebumuncu nasebumnandini” obukhona emakethe.
