ʻO nā hui nui i helu ʻia ma ka ʻoihana adipic acid: Huafeng Chemical (002064), Shenma (600810), Hualu Hengsheng (600426), Danhua Technology (600844), Kailuan (600997), Yangmei Chemical (600691) E kali.
Ke hoʻonui wikiwiki nei ka mana hana o ka waikawa adipic i koʻu ʻāina, a haʻahaʻa mau ka helu hana.Ke hoʻomau nei ka hoʻomohala ʻana o ke kaʻina hana adipic acid o koʻu ʻāina a ke hōʻike mālie ʻia nei nā kumukūʻai, ua lilo koʻu ʻāina i mea hana nui loa o ka honua o ka adipic acid, me ka hiki ke hana ma kahi o 2.655 miliona tons ma 2019, hoʻonui makahiki-ma-makahiki. ʻo 6.0%, a me ka ulu ʻana o ka hui ʻana a hiki i ʻelima mau makahiki.9.1%, aʻo ka ulu ʻana o ka hui honua i ka manawa like he 3.9% wale nō.I ka makahiki 2019, ua helu ʻia ka mana hana adipic acid o Kina no 54% o ka huina o ka honua.I ka makahiki 2020, hiki i ka 2.71 miliona tons ka nui o ka hana ʻana o ka waika adipic, ka piʻi ʻana o ka makahiki he 2.65%, a ʻo ka CAGR e hōʻea i 15.5% mai 2009 a 2020. ʻO ka ulu ʻana o ka noi o lalo, ua hoʻokūkū nui ka mākeke adipic acid i nā makahiki i hala iho nei, a ua mālama ʻia ka nui o ka hoʻohana ʻana ma kahi o 60%, a ua paʻa ka nui o nā mea hana i kahi kūlana pani no ka manawa lōʻihi.
ʻO nā ʻoihana hana ʻakika adipic o Kina ka mea i hōʻike nui ʻia e nā hui nui e like me Huafeng Chemical, China Shenma, Haili Chemical, a me Qilu Hengsheng.ʻO ka CR3 i ka makahiki 2020 he 64.6%, a ʻoi loa ka mana o ka hana.Ma waena o lākou, ʻo ka hui alakaʻi, ʻo Huafeng Chemical, he 735,000 tons o ka adipic acid, ʻo ia ka mea nui loa o ka honua i ka mana hana a loaʻa iā ia ka mākeke kūloko ma mua o 40%.
I kēia manawa, he mea kūʻai nui ʻo Kina i ka waikawa adipic, a ke alakaʻi nei ka nui o ka ulu ʻana i ka honua.I ka makahiki 2019, ʻo ka hoʻohana ʻana o koʻu ʻāina i ka adipic acid he 1.139 miliona tons, kahi hoʻonui makahiki o 2.0%, a ʻoi aku ka lohi o ka ulu ʻana ma mua o ka wā ma mua.ʻO ka nui o ka ulu ʻana o ka hoʻohana ʻana i ka waikawa adipic i koʻu ʻāina i nā makahiki ʻelima i hala iho nei he 6.8%, ʻoi aku ka kiʻekiʻe ma mua o ka ulu ʻana o ka hui honua he 3.8%.I ka makahiki 2020, ʻo ka hoʻohana ʻana i ka ʻakika adipic he 1.27 miliona tons.
He ʻokoʻa ke ʻano o ka hoʻohana ʻana i ka ʻakika adipic i koʻu ʻāina mai ʻEulopa a me ʻAmelika Hui Pū ʻIa.I waena o lākou, ʻo ka polyester polyol ka mea nui loa o ka hoʻohana ʻana i nā huahana hope e like me ka polyurethane slurry, nā kāmaʻa sole stock solution a me ka thermoplastic polyurethane elastomer.I ka makahiki 2020, ʻo ka nui o ka PU slurry, ka hoʻonā waiwai hoʻokahi a me ka PA66 i ka hoʻohana ʻana i lalo o ka wai adipic he 38.2%, 20.7% a me 17.3%, kēlā me kēia.Hoʻoulu ʻia e ka ulu ʻana o ka noi o lalo, ʻo ka hoʻohana ʻana i ka waika adipic i hōʻike i ka ulu mau.Ma lalo o ke kauoha palena plastic, loaʻa i ka PBAT kahi ākea hoʻomohala ākea, kahi i hāpai ai i kahi koi nui no ka adipic acid.
