Izinkampani ezinkulu ezisohlwini embonini ye-adipic acid: i-Huafeng Chemical (002064), i-Shenma (600810), i-Hualu Hengsheng (600426), i-Danhua Technology (600844), i-Kailuan (600997), i-Yangmei Chemical (600691) Ima.
Amandla okukhiqiza i-adipic acid ezweni lami akhula ngokushesha, futhi izinga lokusebenza lihlala liphansi.Njengoba ukuthuthukiswa kwenqubo ye-adipic acid yezwe lami kuqhubeka nokuvuthwa futhi izinzuzo zezindleko zibonakala kancane kancane, izwe lami selibe umkhiqizi omkhulu we-adipic acid, enamandla okukhiqiza cishe amathani ayizigidi ezingu-2.655 ngo-2019, ukwanda konyaka ka-6.0%, kanye nezinga lokukhula elihlanganisiwe elifika eminyakeni emihlanu.9.1%, kuyilapho izinga lokukhula okuhlanganisiwe emhlabeni wonke ngesikhathi esifanayo lalingama-3.9% kuphela.Ngo-2019, umthamo wokukhiqiza i-adipic acid waseChina ubalele ama-54% engqikithi yomhlaba.Ngo-2020, amandla okukhiqiza asekhaya e-adipic acid azofinyelela amathani ayizigidi ezingu-2.71, ukukhuphuka konyaka ngonyaka ngo-2.65%, kanti i-CAGR izofinyelela ku-15.5% kusukela ngo-2009 kuya ku-2020. Njengoba izinga lokunwetshwa kwamandla okukhiqiza lishesha kakhulu izinga lokukhula kwesidingo esingaphansi komfula, imakethe yasekhaya ye-adipic acid ibinokuncintisana kakhulu eminyakeni yamuva nje, futhi izinga lokusebenzisa amandla ligcinwe cishe ku-60%, futhi amasethi amaningi emishini kade esesimweni sokuvalwa.
Izinkampani zaseChina ezikhiqiza i-adipic acid zimele ikakhulukazi izinkampani ezinkulu ezifana ne-Huafeng Chemical, i-China Shenma, i-Haili Chemical, ne-Qilu Hengsheng.I-CR3 ngo-2020 ingama-64.6%, futhi umthamo wokukhiqiza ugxile kakhulu.Phakathi kwazo, inkampani ehamba phambili, i-Huafeng Chemical, inamandla amathani angu-735,000 e-adipic acid, enkulu kunazo zonke emhlabeni ekukhiqizeni umthamo futhi inesabelo semakethe yasekhaya esingaphezu kuka-40%.
Njengamanje, i-China ingumthengi omkhulu we-adipic acid, futhi izinga lokukhula elisetshenziswayo lihamba phambili emhlabeni.Ngo-2019, ukusetshenziswa kwezwe lami kwe-adipic acid bekungamathani ayizigidi eziyi-1.139, okuwukunyuka konyaka ngo-2.0%, futhi izinga lokukhula belihamba kancane kunangaphambili.Izinga lokukhula elihlanganisiwe lokusetshenziswa kwe-adipic acid ezweni lami eminyakeni emihlanu edlule lingu-6.8%, elingaphezulu kakhulu kunezinga lokukhula elihlanganisiwe emhlabeni wonke lika-3.8%.Ngo-2020, ukusetshenziswa kwasekhaya kwe-adipic acid kuzoba amathani ayizigidi eziyi-1.27.
Isakhiwo sokusetshenziswa kwasekhaya kwe-adipic acid ezweni lami sihlukile kunesaseYurophu nase-United States.Phakathi kwazo, i-polyester polyol iyinkambu yesicelo esikhulu kunazo zonke ezansi nomfula, esetshenziselwa ikakhulukazi ukukhiqiza imikhiqizo yokugcina efana ne-polyurethane slurry, isisombululo se-shoe sole stock kanye ne-thermoplastic polyurethane elastomer.Ngo-2020, izilinganiso ze-PU slurry, isixazululo sesitoko sodwa kanye ne-PA66 ekusetshenzisweni kwasekhaya kwe-adipic ephansi komfula kuzoba ngu-38.2%, 20.7% no-17.3%, ngokulandelana.Kukhuthazwa ukukhula kwesidingo esingaphansi komfula, ukusetshenziswa kwasekhaya kwe-adipic acid kubonise ukukhula okuqhubekayo.Ngaphansi komkhawulo we-plastic order, i-PBAT inendawo yokuthuthuka ebanzi, ebangele isidingo esikhulu se-adipic acid.
