Kupereka kwathunthu kwa glacialasidi asidimsika mu Ogasiti ndi wokwera, ndipo ena kunsi kwa mtsinje uli mu nyengo yopuma, kotero kufunikira kwa asidi acetic kungakhale kochepa.Popeza pali mabizinesi ocheperako mwezi uno, Shanghai Huayi ndi Dalian Hengli okha ndi omwe ali ndi mapulani okonzanso, zoperekera zimakhalabe zapamwamba, ndipo kuwerengera kwafakitale kuli pamlingo wapakatikati.Ndizovuta kuthandizira kukwera kwamitengo chifukwa pali zinthu zambiri zoyipa pamsika wanthawi yochepa wa glacial acetic acid.

M'zaka zaposachedwa, kuchuluka kwa glacial acetic acid ndi mafakitale ake akuluakulu akumunsi kwawonetsa kukula.Komabe, kufalitsa phindu mumndandanda wamakampani sikuli bwino.M'tsogolomu, idzakhalabe imodzi mwazomwe zimapangitsa kuti phindu likhale lopindulitsa komanso liwonjezeke.Kuchuluka kwa glacial acetic acid kuyenera kukwera kwambiri.Pa nthawiyo, malire pakati pa kupereka ndi zofuna adzasweka.

Ngakhale kuchuluka kwa glacial acetic acid kukukulirakulira pang'onopang'ono, kumwa kukuwonetsanso kukula, koma kufalikira kwa phindu pamakina am'makampani sikuli koyenera, ndipo phindu lina m'munsi mwa mtsinje silinganene kuti ndi labwino.

Kuchuluka kwa glacial acetic acid kukukula pang'onopang'ono

Munthawi ya 2018-2022, kuchuluka kwa glacial acetic acid ku China kudakwera pang'onopang'ono, mothandizidwa ndi kukula kwa kufunikira kwa kutsika kwamadzi komanso phindu labwino.Pofika mu 2022, mphamvu yapachaka ya glacial acetic acid ndi matani 10.46 miliyoni, kukwera 18 t.86% kuyambira 2018.

Pazaka zisanu zapitazi, mitengo yonse ya glacial acetic acid yakhala ikukwera, mothandizidwa ndi kukwera kwa kufunikira kwapakhomo komanso msika wogwira ntchito kunja.Panthawi imodzimodziyo, yakhala ndi kusiyana kwakukulu kwamtengo wapatali ndi methanol yaiwisi nthawi zambiri, zomwe zimapangitsa kuti pakhale phindu lalikulu komanso nthawi yayitali yopindulitsa.

Mu 2017-2018, chomera chakunja cha glacial acetic acid sichinali chokhazikika, ndipo msika wotumizira kunja udapereka chithandizo kumsika wakunyumba.Kuphatikiza apo, ndi kuchepa kwa kuchuluka kwa acidic acid m'nyumba komanso kukula kwa mitsinje, kufunikira kwa glacial acetic acid kwangowonjezereka, zomwe pamodzi zidathandizira kukwera kwamitengo yapakhomo ya glacial acetic acid.Ngakhale kuti mchitidwewu ndi wofanana ndi wa methanol wakuthupi, kusiyana kwamitengo kukukulirakulirabe ndipo phindu limakula.mu 2018, phindu lalikulu pamsika wakum'mawa kwa China linali pafupifupi 1,753 yuan/ton.mu 2019-2020, zoweta glacial acetic acid mphamvu kupanga pang'onopang'ono kukwera ndi kukwera.Kufuna kumatsika pang'onopang'ono chifukwa cha zinthu zosayembekezereka.Mitengo yapakhomo ya glacial acetic acid ndi yosasunthika, ndipo kusiyana kwamitengo ndi methanol kumatsika pang'ono.mu 2020, phindu lalikulu pamsika wakum'mawa kwa China ndi pafupifupi 504 yuan/ton.mu 2021, ngakhale mitengo ya methanol ndi glacial acetic acid ikukwera, mtengo wa glacial acetic acid ukukwera kwambiri chifukwa cha kukwera kwa kufunikira kwapakhomo ndi kunja komanso kuchepa kwapang'onopang'ono, zomwe zimapangitsa kusiyana kwamitengo pakati pa ziwirizi kupitilirabe. kulitsa.Kuchuluka kwapakati pachaka pamsika wa East China kunali pafupifupi RMB399/ton.41%.

Ngakhale kuti phindu linali lalikulu kwambiri, kufunikira kwa kutsika kwamadzi kunawonetsa kukula, zomwe zidapangitsa opanga omwe alipo komanso osewera atsopano amsika kupanga mapulani atsopano a glacial acetic acid, ambiri omwe adakhazikitsidwanso.

Kufuna kwa m'munsi kwamtsogolo kukukulirakulirabe

Palinso mapulani opangira mphamvu zatsopano zazinthu zambiri zakunsi kwa mtsogolo, zomwe zikuyendetsa kukula kwa glacial acetic acid.

Kuchokera mu 2021 mpaka 2022, mphamvu yopanga ma EVA ikukula mwachangu ndipo zinthu zikuyandikira kukula kwakukulu kwa VA vinyl acetate, ndikuwonjezeka kwakukulu kwa kufunikira kwa vinyl acetate, kukulitsa mphamvu yopanga vinyl acetate, komanso kusowa kodziwika bwino kopanda calcium carbide.Kuyambira 2022, ma calcium carbide ena adawonjezeredwa kwa omwe akugwiritsa ntchito ethylene, njira yaku China ya ethylene acetate yasintha kuchoka pakuchulukirachulukira kupita ku zovuta zamapangidwe.EVA ikuganiza pang'ono zodzipangira ethylene acetate chifukwa chazovuta komanso mtengo wogula ndi ogwiritsa ntchito.Mpaka nthawiyo, ma projekiti angapo omwe akumangidwa akupitilira ndipo mphamvu yopanga ethylene vinyl acetate idzatulutsidwa mu 2023.

Ethyl acetate ndi imodzi mwazinthu zazikulu zakutsika kwa glacial acetic acid.M'zaka zaposachedwa, kutsutsana pakati pa kupezeka ndi kufunikira kwa ethyl acetate kwakhala kokulirapo, ndipo kukula kwa mphamvu kukucheperachepera.2022-2023, mphamvu zatsopano zikadalipobe m'makampani omwe alipo, makamaka kukulitsa gawo lamakampani, kuchepetsanso ndalama komanso kukonza bwino.Kuphatikiza apo, ndi zomwe zikuchitika pano pakuphatikizidwa mumakampani a petrochemical zikuwonekeratu, makampani ena akukonzekera kumanga mbewu zatsopano za ethyl acetate kuti akulitse unyolo wa mafakitale.Komabe, chifukwa cha njira yosavuta yopangira ethyl acetate, kusintha kwachangu kwa zida zapakhomo ndi kupanga zosinthika, makamaka kutengera kusintha kwa mtengo ndi kufunikira, kuchuluka kwa zotulutsa kwakhala pang'onopang'ono m'zaka zaposachedwa.

Pankhani ya acetic anhydride, m'zaka zaposachedwa, zida zatsopano ndi zida zachikale zimakhalapo, ndipo kupezeka kwathunthu kukuwonetsa kukula.Malinga ndi momwe amagwiritsidwira ntchito, amagwiritsidwa ntchito kwambiri popanga acetate fiber, intermediates mankhwala, intermediates mankhwala ophera tizilombo, zonunkhira, utoto, zowonjezera chakudya, mankhwala kutaya madzi m'thupi ndi zina.Zomera zina zapanyumba za acetic fiber zimakhala ndi zomera za acetic anhydride, ndipo kuphatikizana m'minda ina sikokwezeka.M'tsogolomu, zomera za acetic anhydride zidzamangidwabe.Ningxia Donghe akufuna kukhazikitsa matani 150,000 mu theka lachiwiri la chaka chino.Henan Ruibai akukonzekeranso kumanga chomera chatsopano cha acetic anhydride, ndipo mphamvu yopangira mafakitale ikuyembekezeka kupitiriza kukula.Acetic anhydride ili ndi madera ambiri akumunsi ndipo pali malo ena oti akule pambali yofunikira, koma ndi kuwonjezeka kwa mphamvu zopanga, makampaniwa adzakhala opikisana kwambiri.

Ma projekiti atsopano a glacial acetic acid mtsogolomo, kuchuluka kwa zinthu ndi kufunikira kungathe kusweka
Kuchita bwino kwa phindu m'zaka zaposachedwa, komanso kukwera kosalekeza kwa kutsika kwa mitsinje, kumapangitsa kuti glacial acetic acid ipitirire kukwera, ndipo zaka zitatu zikubwerazi ndi chimodzimodzi.

Gome ili pamwambapa likuwonetsa mapulani atsopano a glacial acetic acid m'zaka zitatu zikubwerazi, kuphatikiza makampani ena alinso ndi mapulani atsopano omanga ndi kukulitsa, zitha kuwoneka kuti glacial acetic acid kukula kwamtsogolo kukuyembekezeredwabe. chachikulu.Ngakhale kuti kufunikira kwa kumunsi kwa mtsinje kudzakhalanso ndi kukwera kosalekeza, koma ngati kungatengeretu kuchuluka kwa glacial acetic acid sikuyenera kuwonedwa, ndipo sitinganene kuti glacial acetic acid ku China idzakhala ndi mphamvu zambiri.
