Kuva muri Werurwe, isoko rya styrene ryibasiwe n’ibiciro bya peteroli mpuzamahanga, igiciro cyagiye kizamuka, guhera ku mutwe w’ukwezi kwa 8900 / toni) cyazamutse vuba, gica ku gipimo cy’amafaranga 10,000, kigera ku rwego rwo hejuru mu mwaka. Kugeza ubu ibiciro byasubiye inyuma gato kandi igiciro cyisoko rya styrene kiriho ni 9.462 yu toni.

Ati: "N'ubwo ibiciro bya styrene bikiri ku rwego rwo hejuru, ariko ntibishobora kugabanya umuvuduko w’ibiciro, hamwe n’ingaruka z’icyorezo cyoherezwa mu mahanga cyoherezwa mu mahanga gikennye cyane, bigatuma abakora styrene benshi barwanira umurongo ucika intege, cyane cyane ibigo by’ibikoresho bidahujwe bivuza induru kuri byinshi. Ukurikije isoko biteganijwe ko bizarekurwa, ibigo by’ibanze bikomeza kuba intege nke ndetse n’ibindi bintu, byitezwe ko ibigo by’ibikoresho bitarashyirwa mu bikorwa mu gihe gito. Mu isesengura, Wang Chunling, umusesenguzi mu makuru y’Ubushinwa-Ubumwe.

Kwiyongera kw'ibiciro kw'isoko ntigushobora gufata igipimo cy'ibikoresho fatizo byiyongera

Vuba aha, muri rusange izamuka ry’ibiciro bya peteroli mpuzamahanga, ibiciro bya styrene y’ibikoresho bibiri by’ibanze fatizo Ethylene na benzene nziza byageze ku rwego rwo hejuru mu mwaka. Ku ya 12 Mata, impuzandengo y’isoko rya Ethylene 1573.25 yuan / toni, nintangiriro yumwaka ugereranije no kwiyongera kwa 26.34%; benzene isukuye, guhera mu ntangiriro za Werurwe yatangiye kuzamuka, guhera ku ya 12 Mata, impuzandengo ya 8410 yuan / toni, benzene yera ndetse nintangiriro yumwaka ugereranije no kwiyongera kwa 16.32%. Noneho igiciro cyo hagati yisoko rya styrene nintangiriro yumwaka ugereranije no kwiyongera ni 12,65%, ntishobora gufata isoko ryibikoresho fatizo Ethylene hamwe nizamuka ry isoko rya benzene.

Zhang Ming, ukuriye uruganda rukora ibikoresho byo mu bwoko bwa styrene biva mu mahanga mu Bushinwa bw’Uburasirazuba, yavuze ko ibigo bitihanganira gusa igitutu cy’ibiciro, ahubwo ko byatewe n’ingaruka zatewe no kugabanuka kw’ibisabwa, muri Werurwe, nubwo igiciro mpuzandengo cya styrene kiva hejuru y’uyu mwaka, ariko kigahatirwa n’igitutu cy’ibiciro, dufite igihombo cya tewolojiya y’amafaranga agera kuri 600 kuri toni y’ibicuruzwa, byagabanutse ku kigero cya 260 mu mwaka ushize.

Nubwo ibiciro bya styrene biri hejuru, ariko benshi mubakora styrene barwanira kumurongo wacitsemo ibice, cyane cyane amasosiyete akora ibikoresho bidahujwe birababara, kuberako ibikoresho fatizo benzene na Ethylene biterwa namasoko yo hanze yibikoresho bidahujwe, ibicuruzwa bya styrene kumasoko yazamutse ntibishobora guhura nibiciro byazamutse, muri iki gihe ukwezi kwa Mutarama kugeza ku gipimo cy’inyungu cy’ibicuruzwa byinjira mu kwezi kwa Gashyantare. Mutarama kugeza Gashyantare.

Ubushobozi bushya bwa Styrene bwiyongereye cyane

Dukurikije imibare, mu 2021, Ubushinwa bushya bwa styrene muri toni miliyoni 2.67 / umwaka. Kandi uyumwaka haribintu byinshi bishya bya styrene. Guhera mu ntangiriro za Mata, Yantai Wanhua toni 650.000 / mwaka, Zhenli toni 630.000 / umwaka, Shandong Lihua Yi toni 720.000 / umwaka zararekuwe, zose hamwe zingana na toni miliyoni 2 / umwaka. Nyuma hazaba peteroli ya Maoming, Luoyang Petrochemical, Tianjin Dagu, ibikoresho bitatu hamwe hamwe toni 990.000 / umwaka byateganijwe ko bizasohoka mugihembwe cya kabiri cyuyu mwaka. Mu gihembwe cya mbere cyuyu mwaka, biteganijwe ko toni miliyoni 3.55 / umwaka zubushobozi bwa styrene zizasohoka. Kubwibyo, uyumwaka, igitutu cyo kugurisha kuruhande rwa styrene kirenze umwaka ushize, gifite ubushobozi buhagije, biragoye kuzamura ibiciro kugirango bishyigikire

Kubera igihombo, ibihingwa byinshi bya styrene mugihembwe cya mbere mugihe cyiperereza bahitamo guhagarika kubungabunga, ariko gahunda nyinshi zo kubungabunga ni ukurangira hagati na nyuma ya Mata. Inganda za styrene ziriho ubu zazamutse zigera kuri 75.9% kuva kuri 74.5% mu mpera za Werurwe. Hebei Shengteng, Shandong Huaxing nizindi nzego nyinshi zita ku kuzimya zizatangira umwe umwe, kandi igipimo cyo gutangira kiziyongera nyuma.

Uhereye kumwaka wose, styrene itanga-uruhande irahagije. Inganda zishingiye ku biteganijwe ko hasohoka ubushobozi bushya bw’umusaruro muri uyu mwaka biteganijwe ko zizacira imanza, kuko nyakwigendera ashobora gukuraho igihombo cya leta, muri rusange afite imyumvire yo kwiheba.

Ingaruka z'ibyorezo, kubura ibyifuzo byo hasi
Bitewe no gukwirakwiza ingingo nyinshi z'icyorezo cyo mu ngo, ibintu bitatu nyamukuru byo munsi ya styrene EPS, polystirene (PS), acrylonitrile-butadiene-styrene terpolymer (ABS) ikwirakwizwa ryibicuruzwa, ibicuruzwa byiyongera cyane. Nkigisubizo, ibihingwa byo hepfo ntibishishikarizwa gutangira akazi, igipimo cyo gutangira muri rusange kiri hasi, kandi ibisabwa kuri styrene mbisi ntabwo bikomeye.

Ikwirakwizwa rya polystirene (EPS): Ubushinwa busanzwe bwibikoresho bitanga 11,050 Yuan, ibarura ry’inganda ntangarugero ryagumanye icyiciro cya toni 26.300, igipimo cyo gutangiza cyaragabanutse kugera kuri 38.87%, ugereranije nintangiriro yigihembwe kigera kuri 55%, kugabanuka cyane.

Polystyrene (PS): Ibitangwa muri iki gihe mu gace ka Yuyao ni amafaranga 10,600, kandi ibarura ry’ibicuruzwa byarangiye mu nganda ntangarugero ryongeye kwiyongera kugera kuri toni 97.800 kuva muri Werurwe, aho igipimo cyo gutangira cyamanutse kigera kuri 65.94%, ugereranije n’urwego rwa 75% mu ntangiriro z’igihembwe, igabanuka rikabije.

Muri rusange, icyorezo cy’icyorezo cy’imbere mu gihugu ubu ntikiramenyekana, kandi ibikoresho byo mu bwoko bwa chimique byangiza mu gihugu ntibishobora kongera kubaho mu gihe gito, bigatuma ibicuruzwa bidahagije bikenerwa na styrene. Kubijyanye no gusubukura ibice byo kubungabunga hamwe nubushobozi bushya bwo kubyaza umusaruro, impuzandengo yikigereranyo cyisoko rya styrene biragoye gusubira mubipimo byamafaranga 10,000, kandi biragoye ko ababikora bakuramo inyungu mugihe gito.
