Kunyangwe mhute yekorona nyowani denda muna 2021 ichiripo, kushandiswa kuri kuwedzera zvishoma nezvishoma nekusvika kwechirimo. Ichitungamirwa nekudzokororwa kwemafuta asina kukora, musika wemakemikari wepamba wakaunza musika wemombe. Panguva imwecheteyo, musika weaniline wakaunzawo nguva yakajeka. Kubva pakupera kwaKurume, mutengo wemusika weaniline wakasvika 13,500 yuan/ton, iyo yepamusoro-soro kubva 2008.

Pamusoro peiyo yakanaka mutengo wedivi, iyo aniline musika inosimuka panguva ino inotsigirwawo nedivi rekupa uye rekuda. Huwandu hwezvivakwa zvitsva hwakaderera pane zvaitarisirwa. Panguva imwecheteyo, kuiswa kukuru kwakagadziridzwa, pamwe nekuwedzera kweMDI yakadzika, rutivi rwekuda rwakanga rwakasimba, uye musika weaniline waikwira. Pakupera kwekota, fungidziro yekufungidzira yakadzikira, zvizhinji zvezvigadzirwa zvakakwira uye aniline yekugadziridza mudziyo yakanga yava kuda kutangazve, uye musika wakatendeuka ndokudonha, unotarisirwa kudzoka kune rationality.

Kubva pakupera kwa2020, huwandu hwenyika yangu hwekugadzira aniline hunosvika matani 3.38 miriyoni, zvichiverengera makumi mana nemana muzana ehuwandu hwekugadzira pasi rose. Kuwandisa kweindasitiri yeaniline, pamwe chete nezvirambidzo kwezvakatipoteredza, kwakadzikisira kuwanikwa mukati memakore maviri apfuura. Hakuzove nekuwedzera kutsva muna 2020, asi zvichisundwa nekukura kwekudzika kweMDI kugadzirwa kwesimba, aniline ichaunza kumwe kuwedzera muna 2021. Jiangsu Fuqiang's 100,000-ton itsva chirimwa chakaiswa kushanda muna Ndira gore rino, uye Yantai Wanhua's 540,000- ton new plant yakarongerwawo kutanga kushanda gore rino. Panguva imwecheteyo, chirimwa cheFujian Wanhua chine matani 360 000 chatanga kuvakwa uye chakarongwa kuti chitange kushanda muna 2022. Panguva iyoyo, huwandu hwekuChina hwekugadzira aniline huchasvika matani 4.3 miriyoni, uye Wanhua Chemical ichavawo mugadziri mukuru weaniline pasi rose. ine simba rekugadzira rematani mamiriyoni maviri.

Kudzika kwemvura kushandiswa kweaniline kwakatetepa. 80% yeaniline inoshandiswa kugadzira MDI, 15% inoshandiswa muindasitiri yerubber additives, uye mamwe acho anoshandiswa muminda yedhayi, mishonga nemishonga inouraya zvipembenene. Zvinoenderana nemakemikari epamhepo manhamba, kubva 2021 kusvika 2023, MDI ichave nekuwedzera kweanosvika 2 miriyoni matani ekugadzira kugona uye ichagaya 1.5 miriyoni matani ehuwandu hwekugadzira aniline. Rubber additives anonyanya kushandiswa mukugadzira matai uye anowedzera akabatana nemusika wemotokari. Munguva yeshure kwedenda, mota nematai zvakakwira kusvika kumwero wakati. Zvinotarisirwa kuti kudiwa kwerubber additives kuchawedzera zvishoma. Nekudaro, munaGunyana 2020, European Union yakazivisa aniline sechikamu 2 carcinogen uye chikamu 2 teratogen, uye inokurudzirwa kurambidza kushandiswa kwayo mune mamwe matoyi. Panguva imwecheteyo, zvipfeko zvakawanda zvezvipfeko zvakabatanidzawo aniline muzvinyorwa zvinorambidzwa mumakore achangopfuura. Sezvo zvinodiwa nevatengi zvekuchengetedza kwezvakatipoteredza uye hutano hunowedzera, chikamu chezasi cheaniline chichava pasi pezvimwe zvirambidzo.

Panyaya yekutenga kunze kwenyika uye kutumira kunze kwenyika, nyika yangu inotengesa kunze kwenyika aniline. Mumakore achangopfuura, huwandu hwekutengesa kunze kwenyika hwave hunosvika 8% yezvakabuda pagore. Nekudaro, huwandu hwekutengesa kunze kwenyika mumakore maviri apfuura hwakaratidza kudzikira gore negore. Pamusoro pekuwedzera kwechido chemumba, denda idzva rekorona, mimwe mitero yakatemerwa neUnited States, uye Indian anti-dumping ndizvo zvikonzero zvikuru zvekudzikira kwekutengesa kunze kwenyika aniline. Customs data inoratidza kuti kunze kwenyika muna 2020 kuchave 158,000 matani, gore-pa-gore kuderera kwe21%. Nyika huru dzinotumira kunze dzinosanganisira Hungary, India neSpain. Wanhua Bosu ine MDI mudziyo muHungary, uye pane kumwe kudiwa kwemba aniline. Nekudaro, iyo Bosu chirimwa chinoronga kuwedzera huwandu hweaniline gore rino, uye iyo yepamba aniline ekunze vhoriyamu ichawedzera kuderera panguva iyoyo.

Kazhinji, kukwira kwakanyanya mumusika weaniline kwakafambiswa nemabhenefiti akawanda maererano nemutengo uye kugovera uye kudiwa. Munguva pfupi, misika yakakwira zvakanyanya uye njodzi dzinodonha chero nguva; mukufamba kwenguva, iyo yakadzika inotsigirwa nepamusoro MDI inoda , Musika uchange uine tariro mumakore anotevera 1-2. Nekudaro, nekusimbiswa kwekuchengetedzwa kwezvakatipoteredza kwemumba uye kupera kwekubatanidzwa kweaniline-MDI, nzvimbo yekugara yemamwe mafekitori inosvinwa, uye kusungwa kwemaindasitiri kunotarisirwa kuwedzera kuwedzera.
