Dutegereje isoko ryimyambarire mu 2023, abari mu nganda bemeza ko isoko ishobora kuba iri murwego rwo hejuru kandi ruto. Uyu mwaka uracyari umwaka ubwo umusaruro wa styrene wagutse vuba. Kurengana igice -year anti-guta birarangiye. Ibicuruzwa byo hanze cyangwa guhanagura guhagarika isoko ryimbere mu gihugu. Mugihe kimwe, ubushobozi bwo hasi burarekurwa. Besium iri munsi ya 2022, inyungu iragoye kwiyongera.
Ubwiyongere bw'umusaruro bushobora kuba 17%
Ati: "Mu 2022, ubushobozi bwa styrene mu gihugu buracyari ku muyoboro mwinshi wo kwiyongera, kandi biteganijwe ko umuvuduko w’ubwiyongere uzagera kuri 20%, ibyo bikaba bizaba ibicuruzwa byihuta by’uruganda rw’inganda mu rwego rw’inganda. Kubera irekurwa ryihuse ry’ubushobozi bushya bw’umusaruro wa styrene, izamuka ry’umusaruro n’igurisha riziyongera, kandi igipimo cy’imikoreshereze y’ubushobozi ntikizaba cyiza ku buryo bushoboka.
Wang Li yavuze ko mu 2023, ibikoresho bishya nka Lianyungang Petrochemical, Zibo Junchen, Petrochemical Guangdong, Petrochemical Zhejiang bishobora gushyirwa mu musaruro, kandi biteganijwe ko umuvuduko w’umusaruro wa styrene uzagera kuri 23%. Niba komisiyo itinze kubera kwaguka kwivuguruza hagati y’ibitangwa n’ibisabwa, umuvuduko w’umusaruro wa styrene muri uyu mwaka urashobora kuba 17%.
Ingaruka zibi, isoko ryumwaka wa styrene rirakora cyangwa rifite icyerekezo cyo hejuru kandi kiri hasi, kandi igiciro cyumwaka cyumwaka ntikizaba munsi ya 2022. By'umwihariko, guhanura ibiciro bizamuka mugihembwe cya kabiri. Ku ruhande rumwe, kubera gukomeza kwaguka kwa styrene muri uyu mwaka, igitutu cy’umusaruro mu gihembwe cya mbere cyari kinini, kandi icyifuzo cyo kurengerwa mu gihe cy’impeshyi cyaragabanutse. Ku rundi ruhande, icyifuzo mu gihembwe cya kabiri cyari giteganijwe gukira, kandi umusaruro wo hasi nawo uzakurikirana. Mu gihembwe cya gatatu n'icya kane, itangwa rya styrene riri ku rwego rwo hejuru kandi ibyifuzo bigenda bigabanuka buhoro buhoro, kandi igiciro gishobora kugabanuka. Birakwiye ko tumenya ko mugihe cyo gufata neza ibikoresho bya styrene, hashobora kubaho umuraba wamasoko azamuka, ariko kwiyongera kugarukira.
Byongeye kandi, ikindi kintu kigira ingaruka kumihindagurikire yisoko rya styrene uyumwaka nuko anti-dumping izarangira. Ku ya 22 Kamena 2018, Minisiteri y’Ubucuruzi yatangaje icyemezo cya nyuma cy’ubushakashatsi bwo kurwanya ibicuruzwa biva muri Koreya yepfo, Tayiwani na Amerika. Nyuma yo kurangiza kurwanya ibiyobyabwenge muri Kamena uyu mwaka, Ubushinwa, nk’igihugu kinini cy’abaguzi muri styrene ku isi, kizakurura ibitekerezo by’abakora styrene ku isi. Nubwo ubushobozi bushya bwo kubyaza umusaruro styrene yimbere mu gihugu burarekurwa kandi ibicuruzwa biva mu mahanga bikomeza kugabanuka, ibicuruzwa bitangwa bizakomeza, kandi inzira nshya y’ubukemurampaka izagenda buhoro buhoro, cyangwa izashyira igitutu ku isoko ry’imbere mu gihe runaka.
Umwanya w'inyungu ukomeje kugabanuka
Muri 2022, usibye inganda za ingenuylene mu gihembwe cya gatatu, igihe gisigaye ahanini cyari mu gihombo. Igihombo cyamahame agera ku 1.000 (igiciro cya toni, kimwe hepfo), hamwe nimpuzandengo ya 379 mumwaka.
Han Xiaoxiao, umusesenguzi w'amakuru ya Longzhong, yizera ko usibye gusohora ku buryo bugaragara ubushobozi bushya bwo gukora, ikindi kintu cy'ingenzi ari uko igiciro kinini gikomeje kotsa igitutu. Benzene yuzuye ni kimwe mu bikoresho fatizo bya styrene, kandi ihindagurika ry’ibiciro ni ingenzi cyane kuri styrene.
Mu gice cya mbere cya 2022, igiciro cya benzene cyera cyazamutse cyane kubera itangwa ryinshi hamwe n’ibiciro biri hejuru y’ibiciro byo hanze, kandi byadindije mu gice cya kabiri cy’umwaka bitewe no gukusanya ibicuruzwa biva mu mahanga hamwe n’ibicuruzwa byinjira ku cyambu, igiciro cy’umwaka kigera ku 9000.
Mu myaka ibiri ishize, itandukaniro ryibiciro hagati ya benzene nziza na styrene ryaragabanutse cyane. Mu myaka yashize, itandukaniro ryibiciro hagati ya benzene yera na styrene ryagumishijwe mu 2000 ~ 2500, ryagabanutse kugera ku 1000 ~ 1500 mu myaka ibiri ishize, kandi rimwe na rimwe 200 ~ 500 gusa. Muri 2022, uruganda rwa styrene hamwe ninyungu nziza kubikoresho fatizo birangira benzene nziza.
Muri 2023, igiciro cya benzene yuzuye mugice cya mbere cyumwaka cyangwa ihungabana ryinshi, igice cya kabiri cyumwaka cyangwa ibyago byinshi byo kugwa. Hariho inganda nyinshi zo hasi za benzene nziza. Dufatiye ku kigereranyo cy’imikoreshereze, styrene iracyari igicuruzwa kinini cyo gukoresha benzene nziza, kingana na 47%. Muri icyo gihe, uyu mwaka ubushobozi bwa styrene bukomeje kwaguka byihuse, ibisabwa kuri benzene isukuye biracyakomeza umuyoboro. Mugihe cya "double carbone", kubera igipimo cyinganda zikora kokisi ntizihagije, kugereranya ibikoresho fatizo byo kugemura bitagabanijwe, biteganijwe ko uyumwaka igiciro cya benzene cyera giteganijwe gukomeza ibintu birangiye.
Mu giciro kinini hiyongereyeho gufata, inganda zo mu bwoko bwa styrene zikora kandi zikora ziracyafite igitutu kinini, umwanya wunguka cyangwa uzakomeza gukanda.
Kuvuguruza amasoko n'ibisabwa ntabwo bifite ishingiro
Polystyeyrene (PS), Umusatsi Polystyeyrene (EPS), Acryl -butadiene -Tartylene Poin Poin (ABS) ninzira eshatu nyamukuru zimanuka ya styrene, bingana hafi 70 zose zikoreshwa na styrene%. Ababishinzwe bemeza ko muri rusange ubushobozi bwo kubyaza umusaruro ibi bitatu byingenzi byamanutse muri uyu mwaka ari bike. Ukurikije ibiteganijwe kunozwa imbere, niba epfo na ruguru yizeye gukoresha neza ibikoresho fatizo, umuvuduko nyawo wa ABS, PS, na EPS urateganijwe Byari 12%, 6%, na 3%, byari munsi cyane ugereranije nubwiyongere bwumusaruro wa 17% bya styrene. Ibi bivuze kandi ko kwivuguruza hagati yo gutanga no gukenera styrene biracyagoye kugabanya neza.
Muri 2023, itangwa rya styrene ryuzura buhoro buhoro. Nubwo ibyifuzo biteganijwe kwiyongera, umuvuduko wubwiyongere uri munsi yikigereranyo cyubwiyongere bwa styrene, kandi ibyoherezwa mu mahanga bizakomeza kuba umuyoboro wingenzi wo kugabanya umusaruro nigitutu cyo kugurisha kugabanya ibicuruzwa n’ibicuruzwa. Ku bijyanye n’ibitumizwa mu mahanga, hamwe n’iseswa ry’imisoro yo kurwanya ibicuruzwa bya styrene, Ubushinwa na Koreya yepfo bizagabanuka cyane. Biteganijwe ko muri rusange ingano yatumijwe muri styrene mugice cya kabiri cyumwaka iziyongera gato. Ariko, kwiyongera kwa styrene bitumizwa ntabwo bizaba binini cyane bitewe no kongera ubushobozi bwo guhatanira amafaranga.
