Ngomhla zingama-26 ku-Okthoba, intengo yemakethe ye-n-butanol yenyukile, ngenani lemakethe elimaphakathi elingu-7790 yuan/ton, okukhuphuke ngo-1.39% uma kuqhathaniswa nosuku lwangaphambilini lokusebenza.Kunezizathu ezimbili eziyinhloko zokwenyuka kwentengo.

1. Ngokumelene nesizinda sezici ezingezinhle njengezindleko ezihlanekezelwe ze-propylene glycol ezansi nomfula nokubambezeleka kwesikhashana kokuthengwa kwezimpahla ezikhona, izimboni ezimbili ze-n-butanol eShandong kanye nezifunda ezisenyakatho-ntshonalanga bezilokhu zisemqhudelwaneni oshubile wokuthumela izimpahla, okuholele ekwehleni okuqhubekayo amanani emakethe.Kuze kube yilolu Lwesithathu, izimboni ezinkulu zaseShandong zandise umthamo wazo wokuhweba, kuyilapho i-n-butanol ezifundeni ezisenyakatho-ntshonalanga ihweba ngenani eliphansi, okubonisa izimpawu zokubuya kwemakethe.

1. Ama-plasticizers aphansi kanye nokuthunyelwa kwabakhiqizi be-butyl acetate sekuthuthukile, kuhlanganiswe nenani eliphansi lempahla eluhlaza ezimbonini, okubangele isidingo esikhulu esithile emakethe.Abakhiqizi abasezingeni eliphansi banomuzwa wokuthenga okuphezulu lapho bengena emakethe, futhi izimboni ezinkulu esifundeni esisenyakatho-ntshonalanga neShandong zithengiswe zombili ngenani eliphansi, ngalokho zenyusa intengo ye-n-butanol emakethe.

Imboni ethile ye-n-butanol e-Ningxia ihlelelwe ukunakekelwa ngeviki elizayo, kodwa ngenxa yokukhiqiza kwayo okulinganiselwe kwansuku zonke, umthelela wayo emakethe unomkhawulo.Njengamanje, umdlandla othile wokuthenga izinto ezingaphansi komfula usemuhle, futhi abakhiqizi abajwayelekile be-n-butanol banokuthunyelwa okushelelayo, futhi sisekhona isikhala sokuthi izintengo zemakethe zesikhashana zikhuphuke.Kodwa-ke, ukuswelakala phansi komfula kwamandla amakhulu kubambezele ukukhula kwemakethe ye-n-butanol.Isikhathi sokuqalisa kabusha kwedivayisi ethile e-Sichuan singaphambi kweshejuli, okuholela ekwenyukeni kokunikezwa kwemakethe, futhi kungase kube nengozi yokwehla kwentengo emakethe yesikhathi esimaphakathi neside.

Imboni ye-DBP iyaqhubeka nokuba sesimweni esizinzile nesinenzuzo, kodwa isidingo sisonke esingaphansi komfula asiphezulu, futhi kunethuba elikhulu lokuthi amadivaysi esikhathi esifushane azogcina umthwalo wawo wamanje.Kulindeleke ukuthi isidingo semakethe ye-DBP sihlale sizinzile ngesonto elizayo.Njengamanje, akubanga khona ukulungiswa okubalulekile ekusebenzeni kwemishini embonini yokukhiqiza uviniga, futhi ngeke kube nemibiko yokulungisa ngesonto elizayo, okuholela ekuguquguqukeni okulinganiselwe kwesidingo semakethe.Izindleko eziyinhloko zokwehla komfula zihlanekezelwe, futhi amabhizinisi ikakhulukazi agxile ekwenzeni izinkontileka, abambezela okwesikhashana ukuthengwa kwezindawo.

Amanani kawoyela ongahluziwe kanye ne-propane ayashintshashintsha emazingeni aphezulu, futhi ukusekelwa kwezindleko kusekhona.I-polypropylene eyinhloko engezansi ihlala ibuthakathaka futhi isemaphethelweni enzuzo nokulahlekelwa, ngokusekelwa okulinganiselwe kwemakethe ye-propylene.Kodwa-ke, okunye ukusebenza komfula bekuhloniphekile, ukuthunyelwa kwabakhiqizi be-propylene okubonisa ukusebenza kahle kwezinsuku ezimbili ezilandelanayo, okuhlinzeka ngokusekela okubalulekile kwamathrendi amanani, futhi abakhiqizi nabo babambe ukuzimisela ukusekela izintengo.Kulindeleke ukuthi amanani emakethe yasekhaya ye-propylene abe namandla futhi ahlanganiswe esikhathini esifushane.

Sekukonke, imakethe ye-propylene inamandla ngokuqhathaniswa ekuhlanganisweni, futhi kusenesidingo esinamandla emakethe engezansi.Ukuthunyelwa kwabakhiqizi be-n-butanol kuhamba kahle, futhi sisekhona indawo yokuthi amanani emakethe yesikhashana akhuphuke.Kodwa-ke, isidingo esibuthakathaka se-propylene glycol endaweni engezansi yomfula sinezingqinamba ezithile ekukhuleni kwemakethe.Kulindeleke ukuthi esikhathini esifushane, ukugxila kwezohwebo kwemakethe ye-n-butanol kuzoshintsha kufinyelele esiphethweni esiphakeme, ngokunyuka okungaba ngu-200 kuya ku-400 yuan/ton.
