Ngomhla zizi-4 kuZibandlela, imakethe ye-n-butanol yaphinde yaqina kakhulu ngenani elimaphakathi lama-yuan angu-8027/ton, okukhuphuke ngo-2.37%

Izolo, intengo yemakethe emaphakathi ye-n-butanol ibingu-8027 yuan/ton, okukhuphuke ngo-2.37% uma kuqhathaniswa nosuku lwangaphambilini lokusebenza.Isikhungo semakethe samandla adonsela phansi sibonisa ithrendi ekhuphukayo kancane kancane, ikakhulukazi ngenxa yezinto ezifana nokukhuphuka kokukhiqizwa komfula, izimo zemakethe eziqinile, nomehluko wentengo owandayo ngemikhiqizo ehlobene efana ne-octanol.

Muva nje, nakuba umthwalo wamayunithi e-propylene butadiene aphansi komfula wehlile, amabhizinisi ikakhulukazi agxile ekwenzeni izinkontileka futhi azimisele kancane ukuthenga izinto ezingavuthiwe.Kodwa-ke, ngokutholwa kwenzuzo evela ku-DBP kanye ne-butyl acetate, inzuzo yenkampani yahlala esigabeni senzuzo, futhi ngokuthuthuka okuncane kokuthunyelwa kwefekthri, ukukhiqizwa komfula kancane kancane kwanda.Phakathi kwazo, izinga lokusebenza kwe-DBP lenyuke lisuka ku-39.02% ngo-Okthoba laya ku-46.14%, nokukhuphuka ngo-7.12%;Izinga lokusebenza kwe-butyl acetate lenyuke lisuka ku-40.55% ekuqaleni kuka-Okthoba laya ku-59%, nokukhuphuka ngo-18.45%.Lezi zinguquko zibe nomthelela omuhle ekusetshenzisweni kwezinto ezingavuthiwe futhi zanikeza ukusekelwa okuhle emakethe.

Amafekthri amakhulu aseShandong awakadayisi kule mpelasonto, futhi ukusakazwa kwemakethe kwehlile, okukhuthaza umuzwa wokuthenga wehla nomfula.Umthamo omusha wokuhweba emakethe namuhla usemuhle, obuye ukhuphule amanani emakethe.Ngenxa yabakhiqizi abangabodwana abalungiswayo esifundeni esiseningizimu, kukhona ukushoda kwendawo etholakalayo emakethe, futhi izintengo zamabala esifundeni esisempumalanga nazo ziqinile.Okwamanje, abakhiqizi be-n-butanol ikakhulukazi bama umugqa ukuze bathunyelwe, futhi indawo yemakethe iyonke iqinile, o-opharetha abaphethe amanani aphezulu futhi bamanqikanqika ukuyithengisa.

Ngaphezu kwalokho, umehluko wentengo phakathi kwemakethe ye-n-butanol kanye nemakethe ye-octanol yomkhiqizo ohlobene uyakhula kancane kancane.Kusukela ngoSepthemba, umehluko wentengo phakathi kwe-octanol ne-n-butanol emakethe uye wanda kancane kancane, futhi kusukela ngesikhathi sokushicilela, umehluko wentengo phakathi kwakho kokubili usufinyelele ku-4000 yuan/ton.Kusukela ngoNovemba, intengo yemakethe ye-octanol inyuke kancane kancane isuka ku-10900 yuan/ton yaya ku-12000 yuan/ton, ngokunyuka kwemakethe ngo-9.07%.Ukukhuphuka kwezintengo ze-octanol kunomthelela omuhle emakethe ye-n-butanol.

Kusukela kuthrendi yakamuva, imakethe yesikhathi esifushane ye-n-butanol ingase ibe nethrendi encane ekhuphukayo.Nokho, esikhathini esimaphakathi kuya kwelide, imakethe ingase ibe nokuthambekela kokwehla.Izici eziyinhloko ezinomthelela zihlanganisa: intengo yenye impahla eluhlaza, uviniga i-Ding, iyaqhubeka nokukhuphuka, futhi inzuzo yasefekthri ingase ibe senqenqemeni lokulahlekelwa;Umshini othile eSouth China kulindeleke ukuthi uqalise kabusha ekuqaleni kukaDisemba, nokwenyuka kwesidingo sendawo yemakethe.

Sekukonke, naphezu kokusebenza okuhloniphekile kokufunwa phansi komfula kanye nesimo esiqinile emakethe ye-n-butanol, imakethe ithanda ukukhuphuka kodwa kunzima ukwehla ngesikhathi esifushane.Nokho, kukhona ukwenyuka okulindelekile ekuhlinzekweni kwe-n-butanol esigabeni sakamuva, okuhambisana nokwenzeka kokwehla kwesidingo somfula.Ngakho-ke, kulindeleke ukuthi imakethe ye-n-butanol izobhekana nokukhuphuka okuncane esikhathini esifushane kanye nokwehla esikhathini esimaphakathi ukuya esikhathini eside.Ibanga lokuguquguquka kwentengo lingaba phakathi kwama-yuan angama-200-500/ton.
