Nigute umugozi wa polyester uterwa namavuta ya peteroli?

Uburusiya n’igihugu cya kabiri mu bihugu byohereza peteroli nyinshi ku isi, kandi ibicuruzwa byoherezwa mu mahanga bifata 25% mu bucuruzi bwohereza ibicuruzwa hanze.Igiciro cya peteroli nticyahindutse cyane kuva intambara y’Uburusiya na Ukraine yatangira.Mu gihe ibihano byafatiwe Uburusiya n'Uburayi na Amerika byagendaga byiyongera, impungenge zo guhagarika itangwa ry'ingufu z'Uburusiya zariyongereye.Mu minsi itandatu y’ubucuruzi, Brent ya peteroli ya Brent yigeze kwiyongeraho $ 41 / b, bituma igiciro cya peteroli kiva hejuru cyane kuva muri Nyakanga 2008.

Nyamara, ibiryo bya polyester, PSF hamwe na polyester yintambara biracyari murwego rwo hagati kuva 2007. Kuki batihuta?

1. Igiciro cya peteroli gikomoka kubitangwa nibisabwa, kandi bigena ibiciro byibicuruzwa byo hasi.

Ubwiyongere bwa peteroli ya peteroli ahanini yashinze imizi mu bwoba buterwa no gukenerwa gukabije ku ihagarikwa ry’ibicuruzwa bya peteroli by’Uburusiya.Ndetse no gusubukura peteroli ya Irani yoherezwa mu mahanga no gukuraho itegeko ryabuzanyaga peteroli yo muri Venezuwela ntibishobora kuziba icyuho.Rero, itangwa nibisabwa bigena igiciro cya peteroli.

Imbonerahamwe iri hejuru yerekana inzira yumusaruro wa PSF.Igiciro cyibiryo bya polyester = PTA * 0.855 + MEG * 0.335.Igiciro cyibikomoka kuri peteroli bigira ingaruka kubiciro bya PSF kurwego runini.Kubwibyo, hamwe no kuzamuka kwamavuta ya peteroli, urwego rwinganda rwa polyester ruzamuka, harimo nudodo twa polyester.

2. Gukenera ibyifuzo bikurura izamuka ryibiciro bya PSF no kwagura igihombo bigira ingaruka kubitangwa nibisabwa.

Kugeza ubu, PX, PTA na MEG bose bafite igihombo kinini, kandi PTA-PX ikwirakwizwa ndetse ihinduka nabi ku ya 8 Werurwe ku nshuro ya mbere muri dosiye.Ibicuruzwa bya polyester nka PSF, POY, FDY na PET fibre chip byose birakubitwa.Bivuye mubitinda kumanuka bikenewe cyane.Nyuma yiminsi mikuru yiminsi mikuru, inganda zimyenda n imyenda zabonye ibintu byoroshye.Ubwa mbere, hagati y’ifaranga ryinshi, icyifuzo cyaturutse hanze y’Ubushinwa cyaragabanutse.Icya kabiri, urusyo rwo mu majyepfo yuburasirazuba bwa Aziya rwasubukuye umusaruro, kandi amabwiriza amwe yatembereye.Byongeye kandi, kugabanuka kw'amatungo ya polyester byagabanije ibyifuzo byavuzwe mbere y’intambara yo mu Burusiya na Ukraine.Kubera iyo mpamvu, ibicuruzwa byamanutse ntabwo byateye imbere nyuma yikiruhuko cyibiruhuko, bityo, amatungo ya polyester hamwe n’ibiciro bya PSF yamanuwe kugeza ku gipimo gito ugereranije n’amavuta akomeye ya peteroli.

Mu gihombo, ibihingwa byakurikiranye gahunda yo kubungabunga, harimo PX, PTA, MEG, PSF na PFY.Biteganijwe ko igipimo cya PSF kizagabanuka kugera kuri 80% bitinze Mar kuva kuri 86%.Uruganda rwa polyester ntiruteganya guhagarika umusaruro hamwe nububiko buke ninyungu nziza.Noneho itangwa n'ibisabwa murwego rwose rwinganda zirahinduwe.

Intambara yo mu Burusiya na Ukraine yamaze iminsi mirongo kandi iruma hirya no hino.Niba amavuta ya peteroli akomeje guhindagurika hejuru ya $ 110 / b, urwego rwinganda rwa polyester ruzahangana kandi umugozi wa polyester uzagira uruhare runini muri Mata.
