Pa October 26th, mtengo wamsika wa n-butanol unakula, ndi mtengo wamtengo wapatali wa 7790 yuan / tani, kuwonjezeka kwa 1.39% poyerekeza ndi tsiku lapitalo.Pali zifukwa ziwiri zazikulu zowonjezeretsa mtengo.

1. Potsutsana ndi zinthu zoipa monga kutsika mtengo kwa propylene glycol kumtunda ndi kuchedwa kwa kanthaŵi kogula zinthu zaposachedwa, mafakitale awiri a n-butanol ku Shandong ndi kumpoto chakumadzulo akhala pa mpikisano woopsa wotumiza katundu, zomwe zachititsa kuti pakhale kuchepa kosalekeza. mitengo yamsika.Mpaka Lachitatu lino, mafakitale akuluakulu a Shandong adachulukitsa malonda awo, pamene n-butanol kumpoto chakumadzulo amagulitsa ndalama zambiri, kusonyeza zizindikiro zobwereranso pamsika.

1. Makina opangira mapulasitiki otsika komanso kutumiza kwa opanga ma butyl acetate ayenda bwino, kuphatikiza ndi zinthu zochepa zamafuta m'mafakitale, zomwe zapangitsa kuti pakhale kufunikira kwakukulu pamsika.Opanga otsika amakhala ndi malingaliro ogula kwambiri akamalowa mumsika, ndipo mafakitale akulu kumpoto chakumadzulo ndi Shandong onse agulitsa pamtengo wapatali, motero amakweza mtengo wa n-butanol pamsika.

Chomera china cha n-butanol ku Ningxia chidzakonzedwa sabata yamawa, koma chifukwa cha kuchepa kwa tsiku ndi tsiku, zotsatira zake pamsika ndizochepa.Pakalipano, chidwi chogula zinthu zapansi panthaka chikadali chabwino, ndipo opanga ambiri a n-butanol ali ndi zotumiza zosalala, ndipo pali malo oti mitengo yamsika yaifupi ikwere.Komabe, kufunikira kotsika kwamphamvu kwamphamvu kwalepheretsa kukula kwa msika wa n-butanol.Nthawi yoyambitsanso chipangizo china ku Sichuan ili patsogolo pa nthawi yake, zomwe zimapangitsa kuti msika uchuluke, ndipo pangakhale chiopsezo chotsika mtengo pamsika wapakati mpaka wautali.

Makampani a DBP akupitirizabe kukhala osasunthika komanso opindulitsa, koma kufunikira kwakutsika kwapansi sikuli kwakukulu, ndipo pali kuthekera kwakukulu kuti zipangizo zamakono zidzasunga katundu wawo wamakono.Zikuyembekezeka kuti kufunikira kwa msika wa DBP kudzakhalabe kokhazikika sabata yamawa.Pakalipano, sipanakhalepo kusintha kwakukulu kwa kagwiritsidwe ntchito ka zipangizo mufakitale yopanga viniga, ndipo sipadzakhala malipoti okonzekera sabata yamawa, zomwe zimapangitsa kuti msika ukhale wochepa.Mitengo yayikulu yotsika ndikutsika, ndipo mabizinesi amayang'ana kwambiri pakukonza makontrakitala, kuchedwetsa kwakanthawi kugula malo.

Mitengo yamafuta amafuta ndi propane imasinthasintha pamlingo wokwera, ndipo chithandizo chamitengo chidakalipo.Mtsinje waukulu wa polypropylene umakhalabe wofooka komanso pamphepete mwa phindu ndi kutayika, ndi chithandizo chochepa cha msika wa propylene.Komabe, ntchito zina zotsika pansi zinali zabwino, ndi katundu wa opanga propylene akuwonetsa ntchito yabwino kwa masiku awiri otsatizana, kupereka chithandizo chachikulu pazochitika zamtengo wapatali, ndipo opanga amakhalanso ndi chidwi chothandizira mitengo.Zikuyembekezeka kuti mitengo yayikulu yamsika yapakhomo ya propylene ikhala yamphamvu komanso yophatikizana pakanthawi kochepa.

Ponseponse, msika wa propylene ndi wolimba kwambiri pakuphatikizana, ndipo pakufunikabe kufunikira kwakukulu pamsika wakumunsi.Kutumiza kwa opanga n-butanol ndi kosalala, ndipo pali malo oti mitengo yamsika yamsika ikwere.Komabe, kufunikira kofooka kwa propylene glycol kumunsi kwamtunda kuli ndi zopinga zina pakukula kwa msika.Zikuyembekezeka kuti m'kanthawi kochepa, malonda a msika wa n-butanol adzasunthira kumalo apamwamba, ndi kuwonjezeka kwa 200 mpaka 400 yuan / ton.
