【Isingeniso】NgoJulayi, imikhiqizo eketangeni lezimboni le-acetone ibonise kakhulu ukwehla. Ukungalingani kwesidingo sokulethwa kanye nokudluliselwa kwezindleko okungekuhle kuhlale kuyizimbangela eziyinhloko zokwehla kwamanani emakethe. Kodwa-ke, naphezu kokwehla kwemikhiqizo yeketangeni lezimboni, ngaphandle kokwanda okuncane kokulahlekelwa yinzuzo yemboni, inzuzo ye-MMA kanye ne-isopropanol yahlala ngaphezu komugqa we-breakeven (yize inzuzo yabo nayo yayincishisiwe kakhulu), kanti yonke eminye imikhiqizo yahlala ngaphansi komugqa we-breakeven.
Imikhiqizo eketangeni lezimboni le-acetone ibonise ukwehla ngoJulayi
Imikhiqizo eketangeni lezimboni le-acetone yehle kakhulu kule nyanga. Ukungalingani kwesidingo sokulethwa kanye nokudluliselwa kwezindleko okubi kwakuyizimbangela eziyinhloko zokwehla kwemakethe. Ngokuphathelene nobubanzi bokwehla, i-acetone ibone ukwehla kwenyanga nenyanga cishe ngo-9.25%, ibekwa kuqala eketangeni lezimboni. Ukunikezwa kwemakethe ye-acetone yasekhaya ngoJulayi kubonise ukuthambekela okwandayo: ngakolunye uhlangothi, amanye amabhizinisi ayemise ukukhiqizwa kabusha ngaphambilini, njengeYangzhou Shiyou; ngakolunye uhlangothi, iZhenhai Refining & Chemical yaqala ukuthengiswa kwemikhiqizo ngaphandle cishe ngoJulayi 10, okwacasula abantu bangaphakathi embonini, kwacindezela ukugxila kwezingxoxo zemakethe phansi. Kodwa-ke, njengoba amanani eqhubeka ehla, abaphathi babhekene nezingcindezi zezindleko, kanti abanye bazama ukuphakamisa izingcaphuno zabo, kodwa umfutho okhuphukayo wawuntula ukuzinza, futhi amanani okuthengiselana ehlulekile ukunikeza ukwesekwa.
Imikhiqizo ye-acetone esezansi yonke ibonise ukwehla okuzwakalayo. Phakathi kwayo, ukwehla kwenyanga nenyanga kwamanani ajwayelekile e-bisphenol A, isopropanol, kanye ne-MIBK konke kudlule u-5%, ku--5.02%, -5.95%, kanye no--5.46% ngokulandelana. Amanani ezinto zokusetshenziswa i-phenol kanye ne-acetone womabili ehle kakhulu, ngakho-ke uhlangothi lwezindleko lwehlulekile ukusekela imboni ye-bisphenol A. Ngaphezu kwalokho, amazinga okusebenza kwemboni ye-bisphenol A ahlala ephezulu, kodwa isidingo salandela kancane; ngokumelene nesizinda sezingcindezi zokunikezwa kanye nesidingo, ukwehla kwemboni jikelele kwaba kubi kakhulu.
Nakuba imakethe ye-isopropanol ngenyanga ithole ukwesekwa okuhle ngenxa yezinto ezifana nokuvalwa kwe-Ningbo Juhua, ukwehla komthwalo kaDalian Hengli, kanye nokubambezeleka kwempahla yokuhweba yasekhaya, uhlangothi lokufunwa lwalubuthakathaka. Ngaphezu kwalokho, amanani e-acetone yezinto zokusetshenziswa awe ngaphansi kwama-yuan angu-5,000/ton, okwashiya abantu bangaphakathi embonini bengenalo ukuzethemba, ababethengisa kakhulu ngamanani aphansi, kodwa amanani okuthengiselana ayentula ukwesekwa, okwaholela ekuthambekeni kwemakethe okuphansi.
Ukunikezwa kwe-MIBK kwahlala kwanele, kanti amanye amafektri asabhekene nengcindezi yokuthunyelwa kwezimpahla. Izilinganiso zehlisiwe ngesikhala sezingxoxo zangempela zokuthengiselana, kuyilapho isidingo esingezansi sasiphansi, okwaholela ekwehleni kwamanani emakethe. Intengo emaphakathi ye-MMA emakethe eyinhloko yase-East China yehle ngaphansi kophawu lwe-10,000-yuan kule nyanga, kanye nokwehla kwenyanga nenyanga okungu-4.31% entengo emaphakathi yanyanga zonke. Ukwehla kwesidingo ngesikhathi sokuphumula kwakuyimbangela eyinhloko yokwehla kwemakethe ye-MMA.
Inzuzo yemikhiqizo yeketanga lezimboni ngokuvamile yayibuthakathaka
NgoJulayi, inzuzo yemikhiqizo ochungechungeni lwezimboni lwe-acetone yayibuthakathaka ngokuvamile. Njengamanje, imikhiqizo eminingi ochungechungeni lwezimboni isesimweni sokutholakala okwanele kodwa ukulandelwa kwesidingo okwanele; kuhlanganiswe nokudluliswa kwezindleko okungekuhle, lokhu kube yizimbangela zokulahlekelwa kwemikhiqizo yochungechunge lwezimboni. Phakathi nenyanga, yi-MMA kanye ne-isopropanol kuphela ezigcine inzuzo ngaphezu komugqa we-breakeven, kuyilapho yonke eminye imikhiqizo ihlala ngaphansi kwawo. Kule nyanga, inzuzo enkulu yochungechunge lwezimboni yayisagxile kakhulu embonini ye-MMA, ngenzuzo enkulu engaba ngu-312 yuan/ton, kuyilapho ukulahlekelwa kwenzuzo enkulu engokwenkolelo yomkhakha we-MIBK kwanda kwaya ku-1,790 yuan/ton.
Imikhiqizo eketangeni lezimboni le-acetone ingasebenza ngobubanzi obuncane bokushintshashintsha ngo-Agasti
Kulindeleke ukuthi imikhiqizo eketangeni lezimboni le-acetone ingasebenza ngobubanzi obuncane bokushintshashintsha ngo-Agasti. Ezinsukwini eziyishumi zokuqala zika-Agasti, imikhiqizo yeketangeni lezimboni izogxila kakhulu ekugayeni izinkontileka zesikhathi eside, ngentshiseko ephansi yokuthengwa okusebenzayo emakethe. Amanani okuthengiselana azohlinzeka ngokusekelwa okulinganiselwe emikhiqizweni yeketangeni lezimboni. Ezinsukwini eziyishumi eziphakathi nasekupheleni, njengoba ezinye izinhloso zokuthengwa kwezindawo ezingezansi zanda futhi ukukhula kwemakethe "yeGolden September" kusondela, okunye ukufunwa kokuphela kungabuya, futhi amanani okuthengiselana angakha ukwesekwa okuthile kwamanani. Kodwa-ke, ngokwebanga lokushintshashintsha kule nyanga, okulindelwe kuhlala kulinganiselwe.
