Laga soo bilaabo dhinaca baahida, isticmaalka muuqda ee adipic acid wuxuu si joogto ah kor ugu kacayaa heerka kobaca hooseeya sanadba sanadka ka dambeeya 2017-2020.Marka loo eego tirakoobyada, sanadka 2021, baahida hoose ee koollada PU-da ayaa soo kabsanaysa iyo isticmaalka muuqata ee adipic acid ayaa si degdeg ah u koraysa, iyadoo la isticmaalayo cadcad sannadkii 1.52 milyan oo tan, oo kor u kacday 30.08% sannadkiiba.

Laga soo bilaabo qaab dhismeedka baahida aashitada adipic ee gudaha, warshadaha koollada PU waxay ku xisaabtamaan 38.20%, kabaha cayriin ee kabaha cayriin waxay xisaabiyaan qiyaastii 20.71% wadarta baahida, iyo naylon 66 waxay ku xisaabtamaan 17.34%.Adipic acid-ka caalamiga ah waxaa inta badan loo isticmaalaa in lagu soo saaro naylon 66 milix ah.

Soo dejinta iyo heerka dhoofinta warshadaha adipic acid

Laga soo bilaabo heerka soo dejinta iyo dhoofinta, dhoofinta dibadda ee Shiinaha ee adipic acid aad ayey uga badan tahay tan la soo dejiyo, xaddiga dhoofinta ayaa kor u kacay iyada oo qiimaha suuqa adipic acid uu sii socdo.Marka loo eego tirakoobyada, sanadka 2021, tirada dhoofinta adipic acid ee Shiinaha waxay ahayd 398,100 tan, lacagta dhoofina waxay ahayd USD 600 milyan.

Marka loo eego qaybinta meelaha dhoofinta, Aasiya iyo Yurub waxay ku xisaabtameen wadar ahaan 97.7% dhoofinta.Saddexda waddan ee ugu sarreeya waa Turkiga oo leh 14.0%, Singapore 12.9% iyo Netherlands 11.3%.

Habka tartanka warshadaha adipic acid

Marka la eego qaabka tartanka suuqa (awood ahaan), awoodda wax-soo-saarka adipic acid ee gudaha waa mid kooban, iyadoo shanta shirkadood ee ugu sarreeya ee soo saara adipic acid ay ka yihiin 71% wadarta wax-soo-saarka dalka.Marka loo eego tirakoobyada, xaaladda CR5 ee adipic acid ee Shiinaha sanadka 2021 waa: Huafeng Chemical (750,000 tan, xisaabinta 26.82%), Shenma Nylon (475,000 tan, xisaabinta 16.99%), Hualu Hensheng (326,000 ilaa 6% ), Jiangsu Haili (300,000 tan, oo lagu qiyaaso 10.73%), Shandong Haili (225,000 tan, oo lagu xisaabinayo 8.05%).

Horumarka mustaqbalka ee warshadaha adipic acid

1. Farqiga qiimuhu waxa uu ku jiraa wareeg sare

Sannadka 2021, qiimaha adipic acid waxa uu muujiyay isbeddel kor u kacaya taas oo ay ugu wacan tahay qiimaha kor u kaca ee alaabta ceeriinka ah, iyo Febraayo 5, 2022, qiimaha adipic acid wuxuu ahaa 13,650 yuan/ton, kaas oo ahaa mid taariikhi ah.Iyada oo ay saamaysay kor u kaca qiimaha benzene saafiga ah, faafinta adipic acid ayaa hoos ugu dhacday heerar taariikhi ah qeybtii hore ee 2021, iyo tan iyo Oktoobar 2021, qiimaha alaabta ceeriin ayaa dib u dhacay oo faafitaanka adipic acid ayaa sidaas u kordhay.Faafitaanka adipic acid wuxuu ahaa RMB5,373/ton Febraayo 5, 2022, oo ka sarreeya celceliska taariikhiga ah.

2.PBAT iyo naylon 66 wax soo saarka si loo kiciyo baahida

Iyada oo la faafinayo xannibaadda caagga ah, kobaca baahida PBAT ee gudaha, mashaariic badan oo la dhisayo;Intaa waxaa dheer, degaanka ee adiponitrile si ay u xaliyaan dhibaatada naylon 66 qoorta alaabta ceeriin, hoos dhismaha iyo qorsheynta awoodda adiponitrile ka badan 1 milyan oo tan, sii daayo awoodda adiponitrile gudaha si loo dardar naylon gudaha 66 keentay in muddo koritaanka degdeg ah. awoodda, adipic acid waxay keeni doontaa wareeg cusub oo korriin baahida.

Hadda waxaa ku socda dhismaha iyo qorsheynta awoodda PBAT ee in ka badan 10 milyan oo tan, kuwaas oo 4.32 milyan oo tan la filayo in la geliyo wax soo saarka 2022 iyo 2023, tan PBAT ah waxay cuntaa qiyaastii 0.39 tan oo adipic acid ah, taasoo ka dhigaysa baahida adipic acid ee qiyaastii 1.68 milyan oo tan;Dhismaha iyo qorsheynta naylon 66 awoodda 2.285 milyan oo tan, tan naylon 66 ah ayaa cunaysa qiyaastii 0.6 tan oo adipic acid ah, taasoo ka dhigaysa baahida adipic acid ee ku saabsan 1.37 milyan oo tan.
