I-Adipic Acid Industry Chain
I-adipic acid iyi-asidi ebaluleke kakhulu ye-dicarboxylic ezimbonini, ekwazi ukusabela okuhlukahlukene, okuhlanganisa ukwakheka kukasawoti, i-esterification, i-amidation, njll. Iyinhloko yokukhiqiza ye-nylon 66 fiber kanye ne-nylon 66 resin, i-polyurethane ne-plasticizer, futhi idlala indima ebalulekile ekukhiqizeni kwamakhemikhali, imboni ye-organic synthesis, imithi, njll. phenol, butadiene, cyclohexane kanye cyclohexene izinqubo. Njengamanje, inqubo ye-phenol isuswe kakhulu, futhi inqubo ye-butadiene isesigabeni socwaningo. Njengamanje, imboni ibuswa yi-cyclohexane kanye nezinqubo ze-cyclohexene, ezine-benzene, i-hydrogen ne-nitric acid njengezinto zokusetshenziswa.

Isimo Semboni Ye-Adipic
Kusukela ohlangothini lokuhlinzekwa kwe-adipic acid yasekhaya, amandla okukhiqiza i-adipic acid e-China akhula kancane futhi umkhiqizo ukhula kancane unyaka nonyaka. Ngokwezibalo, ngo-2021, umthamo wokukhiqiza i-adipic acid ungamathani ayizigidi ezingu-2.796/ngonyaka, ukukhiqizwa kwe-adipic acid kungamathani ayizigidi ezingu-1.89, ukukhuphuka ngo-21.53% unyaka nonyaka, kanti izinga lokuguqulwa kwamandla lingama-67.60%.

Ngasohlangothini lwesidingo, ukusetshenziswa okusobala kwe-adipic acid kukhuphuka kancane ngezinga lokukhula eliphansi unyaka nonyaka kusukela ngo-2017-2020. Ngokwezibalo, ngo-2021, isidingo esingezansi sokunamathisela kwe-PU siyalulama futhi ukusetshenziswa okusobala kwe-adipic acid kukhula ngokushesha, ngokusetshenziswa okubonakala minyaka yonke kwamathani ayizigidi eziyi-1.52, kwenyuke ngama-30.08% unyaka nonyaka.

Kusukela esakhiweni sesidingo se-adipic acid yasekhaya, imboni yokunamathisela ye-PU ilinganiselwa ku-38.20%, amasoli ezicathulo aluhlaza afinyelela ku-20.71% wesamba esidingekayo, kanti inayiloni engu-66 ithatha cishe u-17.34%. Futhi i-adipic acid yamazwe ngamazwe isetshenziswa kakhulu ukukhiqiza inayiloni engu-66 kasawoti.

Ukungenisa nokuthekelisa isimo semboni ye-adipic acid

Kusukela esimeni sokungenisa nokuthumela ngaphandle, ukuthunyelwa ngaphandle kwe-adipic acid yaseShayina kukhulu kakhulu kunempahla ethunyelwa ngaphandle, futhi inani lokuthekelisa liye lakhuphuka njengoba intengo yemakethe ye-adipic acid iqhubeka nokukhuphuka. Ngokwezibalo, ngo-2021, inani elithunyelwa ngaphandle le-adipic acid e-China lalingamathani angama-398,100, kanti inani lokuthekelisa lalingama-USD 600 wezigidi.

Kusukela ekusabalaliseni izindawo ezithunyelwa ngaphandle, i-Asia ne-Europe ibalele inani elingama-97.7% lokuthunyelwa ngaphandle. Amathathu aphezulu yiTurkey ngo-14.0%, iSingapore ngo-12.9% kanye neNetherlands ngo-11.3%.

Iphethini yokuncintisana yemboni ye-adipic acid

Ngokwephethini yokuncintisana yemakethe (ngomthamo), amandla okukhiqiza i-adipic acid yasekhaya agxile kakhulu, kanti abakhiqizi abaphezulu abahlanu be-adipic acid babalelwa ku-71% wengqikithi yomthamo wokukhiqiza wezwe. Ngokwezibalo, isimo se-CR5 se-adipic acid e-China ngo-2021 sithi: I-Huafeng Chemical (750,000 amathani, i-26.82%), i-Shenma Nylon (amathani angu-475,000, i-accounting engu-16.99%), i-Hualu Hensheng (326,000 yamathani ayi-6, i-accounting engu-11% ye-Jisuang, i-accounting engu-11%). (300,000 amathani, akhawunti 10.73%), Shandong Haili (225,000 amathani, 8.05%).

Umkhuba wokuthuthuka wesikhathi esizayo wemboni ye-adipic acid

1. Umehluko wentengo usemjikelezweni okhuphukayo

Ngo-2021, intengo ye-adipic acid yabonisa ukuguquguquka okunyukayo ngenxa yokukhuphuka kwentengo yezinto ezingavuthiwe eziwela phansi, futhi ngoFebhuwari 5, 2022, intengo ye-adipic acid yayingu-13,650 yuan/ton, eyayiphezulu ngokomlando. Ngokuthonywa intengo ekhuphukayo ye-benzene emsulwa, ukusabalala kwe-adipic acid kwehle kwaze kwaba phansi emlandweni engxenyeni yokuqala ka-2021, futhi kusukela ngo-Okthoba 2021, izintengo zempahla eluhlaza ziye zabuyela emuva futhi ukusabalala kwe-adipic acid kwenyuke ngokufanele. ukusabalala kwe-adipic acid kwaba ngu-RMB5,373/ton ngoFebhuwari 5, 2022, ngaphezu kwesilinganiso somlando.

I-2.PBAT kanye nokukhiqizwa kwenayiloni 66 ukugqugquzela isidingo

Ngokumenyezelwa kokuvinjelwa kwepulasitiki, i-PBAT yasekhaya idinga ukukhula, amaphrojekthi amaningi asakhiwayo; ngaphezu kwalokho, ukwakhiwa kwasendaweni kwe-adiponitrile ukuxazulula inkinga ye-nylon 66 intamo yempahla eluhlaza, ngaphansi kokwakhiwa nokuhlela umthamo we-adiponitrile wamathani angaphezu kwesigidi esi-1, ukukhululwa kwekhono le-adiponitrile elifuywayo ukusheshisa inayiloni yasekhaya 66 ingenise isikhathi sokukhula okusheshayo komthamo, i-adipic acid izoletha umjikelezo omusha wokukhula.

Njengamanje ngaphansi kokwakhiwa nokuhlela umthamo we-PBAT wamathani angaphezu kwezigidi ezingu-10, lapho amathani ayizigidi ezingu-4.32 kulindeleke ukuthi afakwe ekukhiqizeni ngo-2022 no-2023, ithani le-PBAT lisebenzisa amathani angaba ngu-0.39 we-adipic acid, okwenza isidingo se-adipic acid engaba amathani ayizigidi ezingu-1.68; ngaphansi kokwakhiwa nokuhlela inayiloni engu-66 engamathani ayizigidi ezingu-2.285, ithani lenayiloni 66 lidla amathani angu-0.6 e-adipic acid, okwenza isidingo se-adipic acid esingamathani ayizigidi ezingu-1.37.
