Kuwunika kwamakampani acrylonitrile machitidwe ndi mawonekedwe mu 2022

Chiyambi: Ndikukula kosalekeza kwa mafakitale a acrylic ndi ABS resin, kugwiritsidwa ntchito kwa acrylonitrile kukuchulukirachulukira mdziko lathu.Komabe, kuwonjezereka kwakukulu kwa mphamvu kumapangitsa kuti makampani a acrylonitrile ayambe kukhala ochulukirapo komanso osowa.Pansi pa kusagwirizana kwa kupezeka ndi kufunikira, kutsutsana pakati pa kuperekera ndi kufunikira kwa acrylonitrile kukukulirakulira.

Malo ogwiritsira ntchito Acrylonitrile amagawidwa makamaka muzitsulo za acrylic, ABS resin (kuphatikizapo SAN resin), acrylamide (kuphatikizapo polyacrylamide), mphira wa nitrile ndi mafakitale abwino a mankhwala.Chifukwa chake, East China ndiye gawo lalikulu la ABS, acrylic fiber ndi AM/PAM kupanga mphamvu.Ngakhale kuti chiwerengero cha zomera za ABS ndizochepa, mphamvu yopangira gawo lililonse ndi yaikulu, choncho chipangizo cha ABS kuphatikiza ndi acrylamide chimakhala ndi 44% ya mowa wa acrylonitrile.Kumpoto chakum'mawa kwa China, makamaka chomera cha acrylic fiber choimiridwa ndi Jilin chemical fiber, chomera cha acrylamide ku Daqing, ndi gawo la ABS la matani 80,000 ku Jihua ndi pafupifupi 23% ya zomwe zimafunikira.Kumpoto kwa China, fiber ndi amide ndi mafakitale akuluakulu akumunsi, omwe amawerengera 26%.

Ndikukula kosalekeza kwa mafakitale a acrylic ndi ABS resin, kugwiritsiridwa ntchito kwa acrylonitrile kumawonjezeka mosalekeza m'dziko lathu.Makamaka mu 2018, chifukwa cha kukonza pakati pa zipangizo zapakhomo ndi zakunja, mtengo wa acrylonitrile unakwera kwambiri, ndipo phindu linafika pa 4,000-5,000 yuan / tani, zomwe zinayambitsa kuwonjezereka kwachangu kwa mphamvu zopanga.Chifukwa chake, mu 2019, kukuliraku kudadzetsa nthawi yogawa, ndipo zomwe zikuwoneka kuti zimagwiritsidwa ntchito zidakwera kwambiri, ndikuwonjezeka nthawi imodzi ndi 6.3%.Komabe, ndikufika kwa mliri mu 2020, kukula kwake kudatsika.Komabe, kugwiritsidwa ntchito kwa makampani a acrylonitrile kunakulanso kwambiri mu 2021, kukwera ndi 3.9% chaka ndi chaka, makamaka chifukwa cha kuyambiranso kwachuma chapadziko lonse lapansi komanso kuchuluka kwazinthu zogulitsa kunja.

Ponseponse, makampani a acrylonitrile tsopano ali ndi vuto lochulukirapo, zomwe zachititsa kuti fakitale yamakono ngakhale kupanga kuchepetsedwa, koma msika udakalibe bwino kwambiri, malonda akupitirizabe kutaya phindu.Kuonjezera apo, theka lachiwiri la mphamvu yatsopano ya acrylonitrile inakula kwambiri, kuperekedwa kwa zinthu kapena kupitiriza kukwera.Komabe, ABS yokha ndiyomwe ikuyembekezeka kuyika mayunitsi atsopano kunsi kwa mtsinje, ndipo kufunikira kwathunthu ndi kochepa.Pansi pa kusagwirizana kwa katundu ndi zofuna, kutsutsana pakati pa kupereka ndi kufuna kwa acrylonitrile kudzapitirira kuwonjezeka, ndipo zidzakhala zovuta kuonjezera ntchito ya fakitale panthawiyo.Mabizinesi omwe ali ndi mphamvu zambiri zopangira atengapo kanthu kuti achepetse kulemetsa
