Adipic Acid Kev Lag Luam Chain
Adipic acid yog ib qho tseem ceeb hauv kev lag luam dicarboxylic acid, muaj peev xwm ntawm ntau yam kev cuam tshuam, nrog rau kev tsim ntsev, esterification, amidation, thiab lwm yam. Nws yog cov khoom siv tseem ceeb rau kev tsim cov nylon 66 fiber ntau thiab nylon 66 resin, polyurethane thiab plasticizer, thiab plays. lub luag haujlwm tseem ceeb hauv kev tsim tshuaj, kev lag luam organic synthesis, tshuaj, lubricant manufacturing, thiab lwm yam. Cov txheej txheem ntawm adipic acid feem ntau muab faib ua phenol, Cov txheej txheem butadiene, cyclohexane thiab cyclohexene. Tam sim no, cov txheej txheem phenol tau raug tshem tawm ntau, thiab cov txheej txheem butadiene tseem nyob rau theem tshawb fawb. Tam sim no, kev lag luam yog dominated los ntawm cov txheej txheem cyclohexane thiab cyclohexene, nrog benzene, hydrogen thiab nitric acid ua raw khoom.

Adipic Acid Kev Lag Luam Status
Los ntawm cov khoom siv sab hauv tsev adipic acid, kev tsim muaj peev xwm ntawm adipic acid nyob rau hauv Suav teb yog loj hlob qeeb thiab cov zis tau nce qeeb zuj zus txhua xyoo. Raws li kev txheeb cais, xyoo 2021, adipic acid ntau lawm muaj peev xwm yog 2.796 lab tons / xyoo, adipic acid ntau lawm yog 1.89 lab tons, nce 21.53% xyoo-rau-xyoo, thiab lub peev xwm hloov pauv yog 67.60%.

Los ntawm qhov xav tau sab, pom pom kev noj ntawm adipic acid nce tsis tu ncua ntawm kev loj hlob tsawg xyoo los ntawm xyoo los ntawm 2017-2020. Raws li kev txheeb cais, xyoo 2021, qhov kev thov qis qis rau PU muab tshuaj rov qab thiab pom meej ntawm kev noj cov adipic acid loj hlob sai, nrog kev pom tseeb txhua xyoo ntawm 1.52 lab tons, nce 30.08% xyoo-rau-xyoo.

Los ntawm cov qauv ntawm kev thov hauv tsev adipic acid, PU paste kev lag luam suav txog li 38.20%, cov khau tawv nqaij suav txog li 20.71% ntawm tag nrho cov xav tau, thiab nylon 66 suav txog li 17.34%. Thiab thoob ntiaj teb adipic acid feem ntau yog siv los tsim nylon 66 ntsev.

Ntshuam thiab export xwm txheej ntawm adipic acid kev lag luam

Los ntawm cov xwm txheej ntshuam thiab xa tawm, Tuam Tshoj cov khoom xa tawm sab nraud ntawm adipic acid ntau dua li kev xa tawm, thiab tus nqi xa tawm tau nce siab vim tias cov nqi lag luam adipic acid tseem nce ntxiv. Raws li kev txheeb cais, xyoo 2021, kev xa tawm ntau ntawm adipic acid hauv Suav teb yog 398,100 tons, thiab cov nyiaj xa tawm yog USD 600 lab.

Los ntawm kev faib tawm cov chaw xa tawm, Asia thiab Europe suav txog tag nrho 97.7% ntawm kev xa tawm. Peb sab saum toj yog Qaib Cov Txwv nrog 14.0%, Singapore nrog 12.9% thiab Netherlands nrog 11.3%.

Kev sib tw qauv ntawm adipic acid kev lag luam

Nyob rau hauv cov nqe lus ntawm kev ua lag luam kev sib tw qauv (los ntawm lub peev xwm), domestic adipic acid ntau lawm muaj peev xwm yog tseem concentrated, nrog rau sab saum toj tsib adipic acid manufacturers accounting rau 71% ntawm lub teb chaws lub peev xwm ntau lawm. Raws li kev txheeb cais, CR5 qhov xwm txheej ntawm adipic acid hauv Suav teb xyoo 2021 yog: Huafeng Chemical (750,000 tons, suav txog 26.82%), Shenma Nylon (475,000 tons, suav txog 16.99%), Hualu Hensheng (326,000 tons, suav txog 1.6%). ), Jiangsu Haili (300,000 tons, accounting rau 10.73%), Shandong Haili (225,000 tons, accounting rau 8.05%).

Kev txhim kho yav tom ntej ntawm adipic acid kev lag luam

1. Tus nqi sib txawv yog nyob rau hauv lub voj voog nce

Hauv xyoo 2021, tus nqi ntawm adipic acid tau pom qhov hloov pauv nce siab vim qhov nce nqi ntawm cov khoom siv qis qis, thiab thaum Lub Ob Hlis 5, 2022, tus nqi ntawm adipic acid yog 13,650 yuan / ton, uas yog keeb kwm siab. Kev cuam tshuam los ntawm kev nce nqi ntawm cov ntshiab benzene, adipic acid kis tau poob rau hauv keeb kwm qis hauv thawj ib nrab ntawm 2021, thiab txij li lub Kaum Hlis 2021, cov nqi raw khoom tau poob rov qab thiab adipic acid kis tau nce raws li. adipic acid kis tau RMB5,373 / tuj rau Lub Ob Hlis 5, 2022, siab dua qhov nruab nrab ntawm keeb kwm.

2.PBAT thiab nylon 66 ntau lawm los txhawb kev thov

Nrog rau kev tshaj tawm ntawm kev txwv cov yas, PBAT hauv tsev xav tau kev loj hlob, ntau cov haujlwm hauv kev tsim kho; Nyob rau hauv tas li ntawd, lub localization ntawm adiponitrile los daws qhov teeb meem ntawm nylon 66 raw khoom caj dab, nyob rau hauv kev tsim kho thiab npaj adiponitrile muaj peev xwm ntau tshaj 1 lab tons, kev tso tawm ntawm domestic adiponitrile muaj peev xwm mus accelerate lub domestic nylon 66 ushered nyob rau hauv ib lub sij hawm ntawm kev loj hlob sai. Nyob rau hauv lub peev xwm, adipic acid yuav coj mus rau ib puag ncig tshiab ntawm kev thov kev loj hlob.

Tam sim no nyob rau hauv kev tsim kho thiab npaj PBAT muaj peev xwm ntau dua 10 lab tons, ntawm 4.32 lab tons yuav tsum tau muab tso rau hauv kev tsim khoom hauv xyoo 2022 thiab 2023, ib tuj ntawm PBAT siv txog 0.39 tons ntawm adipic acid, tsim kev thov rau adipic acid ntawm txog 1.68 lab tons; nyob rau hauv kev tsim kho thiab npaj nylon 66 muaj peev xwm ntawm 2.285 lab tons, ib tuj ntawm nylon 66 siv txog 0.6 tons ntawm adipic acid, tsim ib qho kev thov rau adipic acid txog li 1.37 lab tons.
