Muna 2023, maindasitiri ese ari muchikamu cheindasitiri chestyryl-ABS-PS-EPS chekuChina apinda muchikamu chekuwanda kwezvinhu, kubva pakuona kwekugona kutsva, styrene neABS zviri pamberi pekukura kwegore negore, zvichiteerana 21% ne41%, asi mwero wekukura kwezvinodiwa uri kunonoka, zvichikonzera kudzikira kuri kuramba kuchiita purofiti yemaindasitiri akasiyana muchikamu cheindasitiri. Kunyanya, purofiti yeABS nePS yakaderera zvakanyanya gore negore, nehuwandu hweinenge 90%. Kugona kweindasitiri muchikamu cheindasitiri kuramba kuchiwedzera mafambiro acho, asi divi rekudiwa kwakaoma kuva nenzvimbo itsva yekukura, maindasitiri ese achatarisana nemamiriro ezvinhu asina kunaka ekusawirirana kwekupa nekudiwa, kudzikira kwekukura kukuru uye indasitiri nezvimwe zvinhu zvakaipa, kumanikidzwa kwekushanda kweindasitiri kwakawedzera zvakanyanya.

Muna 2023, kugadzirwa kwestyrene nekushandiswa kwestyrene kwakaramba kuchikura nekugadzirwa kwepakati kwezvikamu zvitatu.

Kubva muna 2019 kusvika 2023, mwero wekukura kwekugadzirwa kwestyrene muChina waive 16.05%, zvichiratidza kuwedzera kwakasimba gore negore, uye kubva muna 2020-2022, kugadzirwa kwacho kwaive mukuwedzera kukuru, nekuwedzera kweavhareji pagore kweanosvika matani mamiriyoni 1.63. Muna 2023, nenguva itsva yekukwira kwesimba rekugadzira, kugadzirwa kwestyrene kwakawedzera zvakare kusvika pamatani anopfuura mamiriyoni maviri mugore. Kutanga muna 2021, mamiriro ekuwanda kwestyrene yemumba akaoneka zvishoma nezvishoma, uye nekuunzwa kwesimba idzva, kushandiswa kwesimba kwakaderedzwa zvakanyanya. Muna 2023, nekuda kwekugadzirwa kwezvirimwa zviri pasi pemvura, kune kuwedzera kukuru kwekudiwa, izvo zvinodzikamisa kutanga kwekuisa kutsva.

Kubva muna 2019 kusvika 2023, kushandiswa kwe styrene muChina kwakaramba kuchikwira gore negore, nekukura kwe7.89% pagore mumakore mashanu apfuura, uye kushandiswa kwe styrene kwakasvika matani mamiriyoni 16.03 panosvika 2023, kuwedzera kwe13.66% zvichienzaniswa negore ra2022. Kubva muna 2019 kusvika 2021, nekuda kwepurofiti yakanaka ye styrene, kuchinja kwemitengo ye styrene hakuna kukanganisa zvakanyanya kushandiswa kwe styrene. Muna 2022, purofiti yese ye styrene industry ichakwira, uye styrene nezvigadzirwa zve styrene zvicharasikirwa zvishoma nezvishoma, zvichikonzera kushandiswa kwe styrene zvishoma nezvishoma. Muna 2023, kunyangwe purofiti yekugadzirwa kwepasi pemvura isati yakwana, asi pasi pekumanikidzwa kwemakwikwi ekugadzirwa kwakasimba, fekitori iri pasi pemvura iri kuramba ichisimbisa kugadzirwa, panguva imwe chete, kudiwa kwekupedzisira kunewo kushanda kuri nani, kuchinyanya kugaya kuwedzera kwehuwandu hwekugadzirwa kwepasi pemvura, uye pakupedzisira zvichitungamira mukuwedzera kuri pachena kwekudiwa kwestyrene mukati megore.

二.Muna 2024, kugadzirwa kwestyrene kwava "kure", uye kumanikidzwa kwecheni yemaindasitiri kwadzikiswa!

Muna 2024, kuwanikwa kwemidziyo ye styrene uye kudiwa kwayo zvinotarisirwa kuramba zvichiratidza kukura. Sekureva kwedata reLongzhong, kubva pamaonero ehurongwa hutsva hwekudyara hwemidziyo ye styrene muna 2024, seti imwe chete yemidziyo mitsva ye styrene muhafu yechipiri yegore rapfuura, kureva, mudziyo weShandong Jingbo Petrochemical we 600,000 matani pagore unotarisirwa kutanga kushanda munaKurume kusvika Kubvumbi, uye mudziyo we POSM we 450,000 matani pagore we Shenghong Refining and Chemical wakarongwa kutanga kushanda muhafu yechipiri yegore, huwandu hwe 1.05 miriyoni matani pagore. Zvichienzaniswa na2023, kugona kwekugadzira kwegore negore kunotarisirwa kudzikira ne71.62%, uye kuwedzera kwe styrene kwakaganhurirwa mugore rese. Pasi pemvura, mari inotarisirwa kuwanikwa pari zvino, EPS inotarisirwa kunge iine matani miriyoni imwe pagore ehurongwa hwekutanga kwekudyara kwemidziyo mitsva, PS ine matani mamiriyoni 1.25 pagore ehurongwa hwekutanga kwekudyara kwemidziyo mitsva, ABS ine matani mamiriyoni maviri pagore ehurongwa hwekutanga kwekudyara kwemidziyo mitsva.

Muchidimbu: Muna 2023, kugadzirwa kwestyrene kwakaderera kunoonekwa, uye kudiwa kwacho kwakawedzera zvakanyanya, izvo zvinodzikamisa kutanga kwemidziyo mitsva yestyrene. Kunyangwe kugona kukuru kwekugadzira styrene kwakawedzera mukati megore, asi kushaikwa kwekudiwa kwekupedzisira kwekutevera kwakakonzera kudzikira kwekushandiswa kwechigadzirwa, asi nekukura kwemusika, zvinotarisirwa kuti kugona kutsva kwekugadzira styrene muna 2024 kwakaderera pane kuwedzera kukuru kwekuwedzera kwedownstream, uye mamiriro ekuwanikwa kwakasununguka uye kudiwa kwestyrene muna 2024 kuchaderedzwa.
