Zuag qhia tag nrho cov khoom ntawm glacialacetic acidkev lag luam nyob rau lub yim hli ntuj yog siab, thiab ib co downstream yog nyob rau hauv lub off-lub caij, yog li qhov kev thov rau acetic acid tej zaum yuav txwv.Raws li muaj tsawg dua kev lag luam hauv lub hlis no, tsuas yog Shanghai Huayi thiab Dalian Hengli muaj kev npaj kho dua tshiab, cov khoom siv tseem muaj siab, thiab cov khoom lag luam hauv lub Hoobkas yog nyob rau nruab nrab-siab.Nws yog ib qho nyuaj rau kev txhawb nqa tus nqi nce vim tias muaj ntau yam tsis zoo hauv kev lag luam luv luv glacial acetic acid.

Nyob rau hauv xyoo tas los no, kev tsim muaj peev xwm ntawm glacial acetic acid thiab nws cov kev lag luam tseem ceeb hauv qab tau qhia txog kev loj hlob.Txawm li cas los xij, cov nyiaj tau los hauv kev lag luam saw tsis sib npaug.Nyob rau hauv lub neej yav tom ntej, nws yuav nyob twj ywm ib qho ntawm cov tsav tsheb ntawm cov nyiaj tau los thiab kev xav tau nthuav dav.Lub peev xwm muab khoom ntawm glacial acetic acid yog khi kom nce ntxiv.Lub sijhawm ntawd, qhov sib npaug ntawm cov khoom siv thiab kev thov yuav tawg.

Txawm hais tias glacial acetic acid muaj peev xwm nce ntxiv, kev noj haus kuj tseem qhia txog kev loj hlob, tab sis cov nyiaj tau los hauv kev lag luam cov saw tsis sib npaug, thiab cov nyiaj tau los hauv qee qhov qis qis tuaj yeem hais tias tsis zoo.

Glacial acetic acid ntau lawm muaj peev xwm maj mam nthuav

Nyob rau hauv 2018-2022, glacial acetic acid muaj peev xwm tsim nyob rau hauv Tuam Tshoj tsis tu ncua nce, txhawb los ntawm kev loj hlob ntawm downstream thov thiab zoo profitability.Raws li xyoo 2022, qhov muaj peev xwm ua tau zoo txhua xyoo ntawm glacial acetic acid yog 10.46 lab tons, nce 18 t.86% los ntawm 2018.

Tshaj li tsib xyoos dhau los, tag nrho cov nqi ntawm glacial acetic acid tau nce siab, txhawb nqa los ntawm kev xav tau hauv tsev thiab kev lag luam xa tawm.Nyob rau tib lub sijhawm, nws tau tswj hwm tus nqi loj sib txawv nrog cov khoom siv raw methanol feem ntau, ua rau muaj txiaj ntsig zoo thiab lub sijhawm ua haujlwm ntev.

Hauv 2017-2018, txawv teb chaws glacial acetic acid cog pib tsis ruaj khov, thiab kev lag luam xa tawm tau muab kev txhawb nqa rau kev lag luam hauv tsev.Tsis tas li ntawd, nrog kev qeeb ntawm kev lag luam hauv tsev glacial acetic acid muaj peev xwm thiab cov peev txheej qis qis, qhov kev thov rau glacial acetic acid cia li nce, uas ua ke txhawb kev nce ntawm cov nqi hauv tsev glacial acetic acid.Txawm hais tias tus qauv yog qhov pib zoo ib yam li cov khoom siv raw methanol, tus nqi sib txawv tseem nthuav dav thiab cov txiaj ntsig tau nthuav dav.Nyob rau hauv 2018, qhov nruab nrab theoretical tag nrho cov nyiaj tau los nyob rau hauv sab hnub tuaj Tuam Tshoj ua lag luam yog hais txog 1,753 yuan / ton.Nyob rau hauv 2019-2020, domestic glacial acetic acid muaj peev xwm nce tsis tu ncua thiab muab khoom nce.Kev thov poob qis hauv cov theem vim yog yam tsis tau xav txog.Cov nqi glacial acetic acid hauv tsev tsis hloov pauv, thiab tus nqi sib txawv nrog methanol txo qis rau qee qhov.Nyob rau hauv 2020, qhov nruab nrab theoretical tag nrho cov nyiaj tau los nyob rau hauv sab hnub tuaj Tuam Tshoj ua lag luam yog hais txog 504 yuan / ton.Xyoo 2021, txawm hais tias ob qho tib si methanol thiab glacial acetic acid cov nqi tau nce siab, tus nqi ntawm glacial acetic acid nce ntxiv vim qhov nce hauv kev thov hauv tsev thiab txawv teb chaws thiab cov theem qis hauv cov khoom, ua rau tus nqi sib txawv ntawm ob mus ntxiv. nthuav.Qhov nruab nrab txhua xyoo cov paj tau paj nyob rau hauv East Tuam Tshoj kev lag luam yog nyob ib ncig ntawm RMB399/ton.41%.

Txawm hais tias cov txiaj ntsig tau zoo heev, qhov kev thov qis qis tau pom tias muaj kev loj hlob txuas ntxiv, ua rau cov neeg tsim khoom thiab cov neeg ua lag luam tshiab los tsim cov phiaj xwm tshiab glacial acetic acid, feem ntau kuj tau siv.

Yav tom ntej downstream xav tau tseem nce ntxiv

Tseem muaj cov phiaj xwm tshiab rau lub peev xwm tshiab rau feem ntau cov khoom lag luam hauv qab yav tom ntej, tsav tsheb txuas ntxiv kev loj hlob hauv glacial acetic acid muaj peev xwm.

Los ntawm 2021 txog 2022, EVA muaj peev xwm tsim tau sai heev thiab cov khoom lag luam tseem nce mus txog kev loj hlob ntawm VA vinyl acetate cov ntsiab lus, nrog rau kev xav tau ntau ntxiv rau cov yas acetate, kev nthuav dav ntawm vinyl acetate muaj peev xwm, thiab qhov tseem ceeb uas tsis yog calcium carbide txaus txaus.Txij li xyoo 2022, qee qhov khoom siv calcium carbide tau ntxiv rau cov neeg siv khoom siv ethylene qub, Tuam Tshoj tus qauv ethylene acetate mov tau hloov pauv los ntawm cov khoom seem mus rau cov qauv nro.EVA yog ib feem xav txog tus kheej tsim ethylene acetate vim qhov nyuaj thiab nqi ntawm kev yuav khoom los ntawm cov neeg siv.Txog thaum ntawd, ntau qhov haujlwm hauv kev tsim kho tab tom ua thiab ethylene vinyl acetate muaj peev xwm tsim tawm hauv xyoo 2023.

Ethyl acetate kuj yog ib qho ntawm cov khoom lag luam hauv qab ntawm glacial acetic acid.Nyob rau hauv xyoo tas los no, qhov kev tsis sib haum xeeb ntawm kev muab khoom thiab kev thov ntawm ethyl acetate yog qhov tseem ceeb, thiab kev loj hlob ntawm lub peev xwm kuj qeeb.2022-2023, lub peev xwm tshiab tseem pom nyob rau hauv cov tuam txhab uas twb muaj lawm, feem ntau los nthuav qhia kev lag luam, ntxiv txo cov nqi thiab txhim kho kev ua haujlwm.Tsis tas li ntawd, nrog rau cov qauv tam sim no ntawm kev koom ua ke hauv kev lag luam petrochemical tau dhau los ua pom tseeb, qee lub tuam txhab npaj tsim cov nroj tsuag tshiab ethyl acetate los nthuav cov kev lag luam.Txawm li cas los xij, vim yog cov txheej txheem tsim khoom yooj yim ntawm ethyl acetate, kev hloov pauv sai ntawm cov khoom siv hauv tsev thiab cov khoom siv tau yooj yim, feem ntau raws li tus nqi thiab kev thov hloov pauv, cov khoom tsim tawm tau qeeb hauv xyoo tas los no.

Nyob rau hauv cov nqe lus ntawm acetic anhydride, nyob rau hauv xyoo tas los no, cov khoom tshiab thiab cov khoom siv tsis siv tau ua ke, thiab cov khoom siv tag nrho qhia txog kev loj hlob.Los ntawm qhov kev xav ntawm kev noj cov qauv, nws yog tsuas yog siv nyob rau hauv zus tau tej cov acetate fiber, tshuaj intermediates, tshuaj tua kab intermediates, spices, dyes, zaub mov additives, tshuaj dehydration agents thiab lwm yam teb.Qee cov nroj tsuag acetic fiber ntau tau nruab nrog cov nroj tsuag acetic anhydride, thiab kev sib koom ua ke hauv lwm qhov chaw tsis siab.Nyob rau hauv lub neej yav tom ntej, acetic anhydride nroj tsuag tseem yuav nyob rau hauv kev tsim kho.Ningxia Donghe npaj yuav muab 150,000 tons los ua haujlwm hauv ib nrab xyoo no.Henan Ruibai tseem npaj yuav tsim cov nroj tsuag acetic anhydride tshiab, thiab kev tsim cov peev txheej ntawm kev lag luam yuav tsum tau nthuav dav ntxiv.Acetic anhydride muaj ntau qhov chaw hauv qab dej thiab tseem muaj qee qhov chaw rau kev loj hlob ntawm kev thov sab, tab sis nrog kev nce hauv cov peev txheej ntau lawm, kev lag luam yuav dhau los ua kev sib tw.

Ntau cov haujlwm tshiab rau glacial acetic acid yav tom ntej, qhov sib npaug ntawm cov khoom siv thiab kev thov yuav raug tawg
Kev ua tau zoo ntawm cov txiaj ntsig zoo nyob rau xyoo tas los no, nrog rau kev nce ntxiv hauv cov kev xav tau qis qis, ua rau cov khoom siv glacial acetic acid kuj tseem ua kom muaj zog ntxiv, thiab peb xyoos tom ntej no tsis muaj qhov tshwj xeeb.

Cov lus saum toj no qhia tau hais tias qee qhov kev npaj muaj peev xwm tshiab rau glacial acetic acid nyob rau hauv peb lub xyoos tom ntej, ntxiv rau qee lub tuam txhab kuj tseem muaj kev tsim kho tshiab thiab nthuav dav, nws tuaj yeem pom tias glacial acetic acid yav tom ntej muaj peev xwm loj hlob tseem xav tias yuav muaj feem cuam tshuam. loj.Txawm hais tias qhov kev thov qis qis kuj tseem yuav muaj kev txhawb nqa tau nce, tab sis seb nws puas tuaj yeem nqus tag nrho cov khoom ntxiv glacial acetic acid tseem yuav tsum tau soj ntsuam ntxiv, thiab nws tsis tuaj yeem txiav txim siab tias glacial acetic acid nyob rau hauv Suav teb yuav muaj overcapacity.

Chemwinyog lub tuam txhab tshuaj raw khoom lag luam nyob hauv Suav teb, nyob hauv Shanghai Pudong New Area, nrog lub network ntawm cov chaw nres nkoj, cov chaw nres nkoj, tshav dav hlau thiab kev tsheb ciav hlau thauj mus los, thiab nrog cov khoom siv tshuaj lom neeg thiab phom sij hauv Shanghai, Guangzhou, Jiangyin, Dalian thiab Ningbo Zhoushan, Suav. , khaws cia ntau tshaj 50,000 tons ntawm cov khoom siv raw khoom txhua xyoo, nrog cov khoom txaus, txais tos yuav thiab nug.ximemail:service@skychemwin.comwhatsapp: 19117288062 Tel: +86 4008620777 +86 19117288062
