Kuva ku ya 25 Gicurasi, styrene yatangiye kuzamuka, ibiciro byacitse ku giciro cya 10,000 / toni, rimwe bigera ku 10.500 / hafi. Nyuma y’ibirori, ejo hazaza ha styrene hongeye kuzamuka cyane kugera kuri 11,000 yuan / toni, bigera ku rwego rwo hejuru kuva ubwo bwoko bwashyizwe ku rutonde.

Isoko ryibibanza ntirishaka kwerekana intege nke, murwego rwo gutanga ibicuruzwa bigaragara kugabanuka nigiciro cyinkunga ikomeye, 7 kamena Isoko ryubushinwa Uburasirazuba igiciro cya styrene cyageze ku 10.950 yuan / toni, bigarura ubuyanja!
Ibiciro bya styrene kumasoko akomeye mugihugu

Kuva mu mpera za Gicurasi, ibihingwa bya styrene byo mu rugo muri gahunda, hanze y’ivugurura byumviswe, Shandong Wanhua, Sinochem Quanzhou, Huatai Shengfu, Bay Qingdao n’ibindi bikoresho biri muri iki gihe cyo guhagarika imyitwarire y’ivugurura, nubwo hari Shandong Yuhuang, Amajyaruguru y’Ubushinwa. Jin gusubukura umusaruro muri iki gihe, ariko muri rusange kureba ivugurura rirenze gukira, bigatuma styrene yo murugo ikoreshwa buri cyumweru ubushobozi bwo gukoresha ubushobozi buri munsi, guhera mumibare yo ku ya 2 kamena, ubushobozi igipimo cyo gukoresha cyaragabanutse kugera kuri 69.02%, gishya kiri hasi mumyaka yashize, kandi muri iki cyumweru haracyari amahirwe yo gukomeza kumanuka.
Hamwe nigabanuka ryikoreshwa rya styrene murugo buri cyumweru, umusaruro wa styrene murugo buri cyumweru wagabanutse icyarimwe, ibarura ryuruganda naryo riri kurwego rwo hasi mumyaka yashize, nubwo icyifuzo cya terminal atari cyiza, ariko uruganda rwa styrene rwatangiye kugabanuka icyarimwe. igihe, amasezerano arasanzwe, birasa nkaho kugurisha nigitutu cyibarura atari byinshi, biha ibiciro bya styrene igice cyinkunga.
Usibye styrene ubwayo kugirango igabanye uruhande rutanga ibyiza, izamuka ryinshi ryibikoresho fatizo benzene nziza muri styrene yazamutse igera ku rwego rwo hejuru mu mwaka ni inguzanyo ikomeye. Kamena mbere na nyuma yUbushinwa Uburasirazuba benzene isukuye ikomeje kuzamuka, guhera ku ya 7 Kamena, Ubushinwa bw’Uburasirazuba bwa benzene bwera bugera kuri 9,990 yu / toni, nabwo ni ingingo nkuru y’umwaka kugeza ubu.
Iburasirazuba Ubushinwa bwera benzene ibiciro byerekana isoko

Vuba aha, kubera ibihe byingendo muri Amerika, toluene yaho yinjiye muri lisansi aho kugirango itagabanywa, maze umusaruro wa benzene ugabanuka. Hasi ya Ethylbenzene na isopropylbenzene irashobora kandi gukoreshwa mubigize lisansi, kandi ikoreshwa rya benzene nziza ryiyongereye, bityo igiciro cya benzene yera muri Amerika cyazamutse cyane ku nkunga y’ibisabwa ndetse n’ibisabwa. Kwuzuzanya hamwe n’ibarura ry’imbere mu gihugu bikomeje kuba hasi cyane, bikamanuka bikagera kuri toni 48.000, bitewe n’igiciro cy’ibicuruzwa byatumijwe mu mahanga, biteganijwe ko bizakomeza urwego ruto rw’ibicuruzwa by’ibyambu by’igihe gito muri Jiangnei.
Nubwo ibikoresho bya benzene byimbere mu gihugu byongeye gutangira bikurikiranye, inzira yo hasi itangira gukomeza kugabanuka, ariko kubera igiciro cyinshi cyikigo cy’ivunjisha, biteganijwe ko benzene itangwa ishobora gukomeza kuba ingume, haracyari abacuruzi kugura cyane, bikurura Ubushinwa bwi Burasirazuba ibiciro bya benzene bikomeje kuzamuka cyane.

Muri make, inkunga ikomeye, hamwe no kuvugurura uruganda rwa styrene rwatewe no kugabanuka kw'ibicuruzwa, kuvanga ibyiza, styrene byazamutse bigera ku rwego rwo hejuru mu mwaka, ariko ibyifuzo byo hasi byo kubikurikirana ntabwo ari byiza, bibuza styrene gukurikirana ibiciro hejuru. icyerekezo, usibye gukenera kwibanda ku kugaruka kwinyungu za styrene, ibikoresho bidahujwe kugirango byongere umusaruro biziyongera, impinduka z ibikoresho.
