Mai i te taha tono, ka piki haere te kohi waikawa adipic i te iti o te tipu o ia tau mai i te 2017-2020.E ai ki nga tatauranga, i te tau 2021, ka hoki mai ano te tono whakararo mo te whakapiri PU me te kaha ake o te kai o te waikawa adipic, me te 1.52 miriona taranata ia tau, ka piki 30.08% ia tau.

Mai i te hanganga o te tono waikawa adipic kāinga, PU whakapiri ahumahi pūkete mo e pā ana ki 38.20%, pūkete hu raw mo e pā ana ki 20.71% o te katoa tono, me te nairona 66 pūkete mo e pā ana ki 17.34%.A ko te waikawa adipic o te ao ka whakamahia te nuinga ki te whakaputa nylon 66 tote.

Te mana kawemai me te kaweake o te ahumahi waikawa adipic

Mai i te mana o te kawemai me te kaweake, he nui ake te nui o nga hua o waho o Haina o te waikawa adipic i nga kawemai, a kua piki ake te moni kaweake i te mea kei te piki haere te utu o te maakete waikawa adipic.E ai ki nga tatauranga, i te tau 2021, ko te rahinga kaweake o te waikawa adipic i Haina ko te 398,100 tone, a ko te moni kaweake he $600 miriona.

Mai i te tohatoha o nga waahi kaweake, ko Ahia me Uropi te katoa o te 97.7% o nga kaweake.Ko te toru o runga ko Turkey me 14.0%, Singapore me 12.9% me te Netherlands me 11.3%.

Te tauira whakataetae o te ahumahi waikawa adipic

I runga i nga tauira whakataetae maakete (ma te kaha), ko te kaha o te hanga waikawa adipic o te kainga he tino kaha, me te rima o nga kaihanga waikawa adipic e 71% o te katoa o te kaha whakaputa o te whenua.E ai ki nga tatauranga, ko te ahuatanga CR5 o te waikawa adipic i Haina i te tau 2021 ko: Huafeng Chemical (750,000 tons, e 26,82%), Shenma Nylon (475,000 tons, e 16,99%), Hualu Hensheng (326,000 tons, kaute mo te 326,000 tons). ), Jiangsu Haili (300,000 tons, e 10.73%), Shandong Haili (225,000 tons, e 8.05%).

Te ahua whanaketanga o te ahumahi waikawa adipic

1. Ko te rereketanga utu kei roto i te huringa whakarunga

I te tau 2021, i whakaatu te utu o te waikawa adipic i te pikinga ake na te pikinga o te utu o nga rawa mata o raro, a, i te Hui-tanguru 5, 2022, ko te utu o te waikawa adipic he 13,650 yuan/ton, i te teitei o mua.I awehia e te pikinga o te utu o te benzene parakore, ka heke te horapa o te waikawa adipic ki te iti o mua i te haurua tuatahi o 2021, a mai i Oketopa 2021, kua heke te utu o nga rawa me te horapa o te waikawa adipic i runga ano.Ko te horahanga waikawa adipic he RMB5,373/ton i te Hui-tanguru 5, 2022, teitei ake i te toharite o mua.

2.PBAT me te nylon 66 hanga hei whakaihiihi i te hiahia

Na te panuitanga o te aukati kirihou, te tipu o te tono a te PBAT o te kaainga, he maha atu nga kaupapa kei te hangaia;i tua atu, te localization o adiponitrile ki te whakaoti i te raruraru o te nylon 66 raw rauemi kaki, i raro i te hanga me te whakamahere adiponitrile kaha o neke atu i te 1 miriona taranata, te tuku o te kaha adiponitrile kāinga ki te whakatere i te naiponitrile kāinga 66 i timata i roto i te wā o te tipu tere. i roto i te kaha, ka uru te waikawa adipic ki te tipu o te hiahia.

I tenei wa kei te hanga me te whakamahere i te kaha o te PBAT neke atu i te 10 miriona taranata, ko te 4.32 miriona taranata ka tukuna ki te hanga i te 2022 me te 2023, he ton o te PBAT e pau ana i te 0.39 toni o te waikawa adipic, ka puta he tono mo te waikawa adipic o tata ki te 1.68 miriona taranata;i raro i te hanga me te whakamahere nylon 66 kaha o 2.285 miriona taranata, he ton o nairona 66 pau e pā ana ki 0.6 taranata o te waikawa adipic, hanga he tono mo te waikawa adipic o e pā ana ki 1.37 miriona taranata.
