Ngo-Okthoba 26, intengo yemakethe ye-N-Butanol yanda, ngentengo ephakathi yemakethe ye-7790 yuan / ton, ukukhuphuka kwe-1.39% kuqhathaniswa nosuku lwangaphambilini. Kunezizathu ezimbili eziphambili zokwanda kwentengo.

1. Ngokumelene ne-backrop yezinto ezingezinhle njengezindleko ezihlanekezelwe ze-towstream propylene glycol kanye nokubambezeleka kwesikhashana kokuthenga impahla, izifunda ezimbili zasenyakatho ntshonalanga zibe nomncintiswano ovuthayo ukuze zibe khona izimpahla, ziholele ekunciphiseni okuqhubekayo ngaphakathi Amanani emakethe. Kuze kube ngaleli sithathu, amafektri amakhulu kaShandong akhulisa ivolumu yawo yokuhweba, kuyilapho uN-Butanol ezifundeni ezisenyakatho ntshonalanga ethengiswa kwiprimiyamu, ekhombisa izimpawu zokuphindisela emakethe.

1. Amapulasitiki aphansi we-Downstream kanye nokuhanjiswa kwabakhiqizi be-Butyl Acetate abathuthukile, kuhambisana nokusungula okuluhlaza okuluhlaza emafektri, okuholela ekufuneni okuthile okuphezulu emakethe. Abakhiqizi abaphansi banomqondo ophakeme wokuthenga lapho ungena emakethe, namafektri amakhulu esifundeni saseNyakatho-Ntshonalanga futhi uShandong usuthengise ngentengo ye-N-Butanol emakethe.

Isitshalo esithile se-n-butanol eNingxia sihlelelwe ukulungiswa ngesonto elizayo, kepha ngenxa yokukhiqizwa kwayo kwansuku zonke okulinganiselwe, umthelela wawo emakethe ukhawulelwe. Njengamanje, enye intshiseko yokuthengwa kwe-Downstream isezingeni elifanele, futhi abakhiqizi abajwayelekile be-N-Butanol banokuthunyelwa okubushelelezi, futhi kusekhona indawo yamanani entengo yesikhathi esifushane ukukhuphuka. Kodwa-ke, abampofu abaphansi phansi kwamandla amakhulu baphoqe ukukhula kwemakethe ye-N-Butanol. Isikhathi sokuqalisa kabusha sedivayisi ethile eSichuan singaphambi kohlelo, okuholela ekwandeni kokuhlinzekwa kwemakethe, futhi kungahle kube nengozi yokuncipha kwentengo emakethe yesikhathi eside.

Imboni ye-DBP iyaqhubeka nokuba sesimweni esizinzile futhi esinenzuzo, kepha ukufunwa kwehlazo okuphelele akuphezulu, futhi kungenzeka ukuthi amathuba aphezulu azogcina umthwalo wabo wamanje. Kulindelwe ukuthi ukufunwa kwemakethe ye-DBP kuzohlala kuzinzile ngesonto elizayo. Njengamanje, akubanga khona ukulungiswa okubalulekile ekusebenzeni kwemishini esitshalweni sokukhiqizwa seviniga, futhi ngeke kube nemibiko yokulungiswa ngesonto elizayo, okuholela ekushintshashintsheni kwemakethe okulinganiselwe. Izindleko ezinkulu ezansi emfuleni ziyavela, futhi amabhizinisi agxile kakhulu ekusebenzeni izinkontileka, okubambezeleka okwesikhashana ukuthenga kwendawo.

Amanani entengo kawoyela we-crude ne-propane aguquguqukayo emazingeni aphezulu, futhi ukusekelwa kwezindleko kusekhona. I-polypropylene ephansi ephansi ihlala ibuthakathaka futhi emaphethelweni wenzuzo nokulahlekelwa, ngokusekelwa okulinganiselwe kwemakethe ye-propylene. Kodwa-ke, okunye ukusebenza kwe-Downstream kwakuhlosiwe, ukuthunyelwa kwabakhiqizi be-Preppener Kulindelwe ukuthi amanani entengo yemakethe ye-Mainteam Depylene Makerlene Personain azoqina futhi ahlanganiswe esikhathini esifushane.

Sekukonke, imakethe ye-propenene iqinile ngokuhlanganiswa, futhi kusekhona isidingo esiqinile emakethe ephansi. Ukuhanjiswa kwabakhiqizi be-N-Buthanol bushelelezi, futhi kusekhona indawo yamanani entengo yesikhathi esifushane akhuphuke. Kodwa-ke, isidingo esibuthakathaka se-Plyylene Glycol ku-Main DownTream sinezithiyo ezithile ekukhuleni kwemakethe. Kulindeleke ukuthi esikhathini esifushane, ukugxila kokuhweba emakethe ye-N-Buthanol kuzoshintshana kuze kube sekupheleni okuphezulu, ngokwanda cishe kwama-200 kuye ku-400 yuan / toni.
