Iinkampani ezinkulu ezidweliswe kwi-adipic acid industry: Huafeng Chemical (002064), Shenma (600810), Hualu Hengsheng (600426), Danhua Technology (600844), Kailuan (600997), Yangmei Chemical (600691) Linda.
Amandla okuvelisa i-adipic acid kwilizwe lam akhula ngokukhawuleza, kwaye izinga lokusebenza lihlala liphantsi.Njengoko uphuhliso lwelizwe lam inkqubo ye-adipic acid iqhubeka nokuvuthwa kwaye izibonelelo zeendleko zibonakala ngokuthe ngcembe, ilizwe lam liye laba lelona lizwe livelisa i-adipic acid, enomthamo wemveliso omalunga ne-2.655 yezigidi zeetoni ngo-2019, ukonyuka konyaka ye-6.0%, kunye nezinga lokukhula elihlanganisiweyo ukuya kwiminyaka emihlanu.I-9.1%, ngelixa izinga lokukhula elihlangeneyo kwihlabathi ngexesha elifanayo laliyi-3.9% kuphela.Ngo-2019, umthamo wokuvelisa i-adipic acid yaseTshayina wenze i-54% yexabiso lilonke lehlabathi.Ngo-2020, umthamo wasekhaya wemveliso ye-adipic acid uya kufikelela kwi-2.71 yezigidi zeetoni, ukunyuka konyaka-ngonyaka we-2.65%, kwaye i-CAGR iya kufikelela kwi-15.5% ukusuka ku-2009 ukuya ku-2020. izinga lokukhula kwemfuno esezantsi, imarike ye-adipic yasekhaya iye yakhuphisana kakhulu kwiminyaka yakutshanje, kwaye izinga lokusetyenziswa kwamandla ligcinwe malunga ne-60%, kwaye ezininzi iiseti zezixhobo bezikwimeko yokuvalwa kwexesha elide.
Iinkampani zaseTshayina zokuvelisa i-adipic acid ikakhulu zimelwe ziinkampani ezinkulu ezifana neHuafeng Chemical, China Shenma, Haili Chemical, kunye neQilu Hengsheng.I-CR3 ngo-2020 yi-64.6%, kwaye umthamo wemveliso ugxininiswe kakhulu.Phakathi kwabo, inkampani ehamba phambili, i-Huafeng Chemical, inomthamo we-735,000 yeetoni ze-adipic acid, eyona nto inkulu kwihlabathi kumthamo wemveliso kwaye inesabelo semarike yasekhaya engaphezulu kwe-40%.
Okwangoku, i-China ingumthengi omkhulu we-adipic acid, kwaye izinga lokukhula kokusetyenziswa kwayo likhokela ihlabathi.Ngo-2019, ukusetyenziswa kwelizwe lam kwe-adipic acid yayiziitoni ezisisi-1.139 sezigidi, ukonyuka konyaka-ngonyaka nge-2.0%, kwaye izinga lokukhula lalicotha kunangaphambili.Izinga lokukhula elidityanisiweyo lokusetyenziswa kwe-adipic acid kwilizwe lam kule minyaka mihlanu idlulileyo yi-6.8%, engaphezulu kakhulu kunezinga lokukhula elidityanisiweyo lehlabathi le-3.8%.Ngo-2020, ukusetyenziswa kwasekhaya kwe-adipic acid kuya kuba yi-1.27 yezigidi zeetoni.
Isakhiwo sokusetyenziswa kwasekhaya kwe-adipic acid kwilizwe lam yahlukile kweyaseYurophu nase-United States.Phakathi kwazo, i-polyester polyol yeyona ndawo inkulu yesicelo esezantsi, esetyenziswa ikakhulu ukuvelisa iimveliso zokuphela ezifana ne-polyurethane slurry, isisombululo sesihlangu sodwa kunye ne-thermoplastic polyurethane elastomer.Ngo-2020, umlinganiselo we-PU slurry, isisombululo se-stock sole kunye ne-PA66 kwindawo ephantsi yokusetyenziswa kwe-adipic acid iya kuba yi-38.2%, i-20.7% kunye ne-17.3%, ngokulandelanayo.Ukukhuthazwa kukukhula kweemfuno ezisezantsi, ukusetyenziswa kwasekhaya kwe-adipic acid kubonise ukukhula okuzinzileyo.Ngaphantsi komyalelo weplastiki, i-PBAT inendawo yophuhliso ebanzi, ethe yavelisa imfuno enkulu ye-adipic acid.
