Kusukela ngo-2023, ukutholwa kokusetshenziswa kwetheminali bekuhamba kancane, futhi isidingo esingezansi somfula asilandelanga ngokwanele.Ngekota yokuqala, umthamo omusha wokukhiqiza wamathani angu-440000 we-bisphenol A waqaliswa, okugqamisa ukungqubuzana kwesidingo sokuhlinzekwa kwempahla emakethe ye-bisphenol A.I-phenol yempahla eluhlaza ishintshashintsha ngokuphindaphindiwe, futhi isikhungo sisonke samandla adonsela phansi siyehla, kodwa ukwehla kuncane kunaleyo ye-bisphenol A. Ngakho-ke, ukulahleka kwemboni ye-bisphenol A sekuyinto evamile, futhi ingcindezi yezindleko kubakhiqizi iyabonakala.
Kusukela ngoMashi, imakethe ye-bisphenol A iye yakhuphuka futhi yehla ngokuphindaphindiwe, kodwa ububanzi bokushintshashintsha kwentengo yemakethe buphelele, phakathi kuka-9250-9800 yuan/ton.Ngemuva komhla ziyi-18 kuMbasa, isimo semakethe ye-bisphenol A "ngokungazelelwe" saba ngcono, ngokukhula kwemibuzo yemakethe ephansi, kanye nokufiphala.

isimo se-bisphenol A imakethe yephukile.

Ngomhla zingama-25 kuMbasa, imakethe ye-bisphenol A eMpumalanga China yaqhubeka nokuqina, kuyilapho imakethe yasekhaya ye-bisphenol A iphakama.Ukunikezwa kwamabala emakethe kuqinisiwe, futhi umnikelo ovela kumnikazi wempahla ukhushulelwe phezulu.Ngokushesha nje lapho abantu emakethe bedinga uphenyo, bazoxoxisana futhi balandele ngokucophelela ngokwezidingo zabo.Esikhathini esifushane, imakethe isebenza ngentengo ephezulu, futhi ikhotheshini yemakethe iyaqhubeka ikhuphukela ku-10000-10100 yuan/ton!

Njengamanje, izinga lokusetshenziswa komthamo wokukhiqiza we-bisphenol A e-China lilinganiselwa ku-70%, ukwehla ngamaphesenti angaba ngu-11 uma kuqhathaniswa nasekuqaleni kukaMashi.Kusukela ngoMashi, umthwalo wamayunithi we-Sinopec Sanjing kanye ne-Nantong Xingchen wehla, iyunithi ye-Cangzhou Dahua yavalwa, futhi izinga lokusebenzisa umthamo wokukhiqiza i-bisphenol A lehla laya cishe ku-75%.I-Huizhou Zhongxin kanye ne-Yanhua Polycarbon zivale ngokulandelana ukuze zilungiswe ekupheleni kuka-March nasekuqaleni kuka-April, futhi zehlisa izinga lokusetshenziswa kwe-bisphenol A umthamo wokukhiqiza wafinyelela cishe ku-70%.Imikhiqizo yomkhiqizi ikakhulukazi ngeyokuzisebenzisela yona kanye nokuphakela amakhasimende esikhathi eside, okuholela ekwehleni kokuthengiswa kwamabala.Ngesikhathi esifanayo, njengoba kunesidingo esingavamile sokuphinda sibeke ezansi nomfula, inani lendawo liyadla kancane kancane.

Kusukela maphakathi nasekupheleni kuka-April, ngenxa yokuhlinzekwa kwasekhaya kanye nokugcwaliswa kabusha kwe-bisphenol A, kanye nokwethulwa kwe-epoxy resin ne-PC, isidingo sokukhiqizwa kwansuku zonke kwe-bisphenol A siye sashintsha kancane kancane safinyelela kubhalansi esimweni sokunciphisa i-inventory ngo-April.Kusukela ngoFebhuwari, umkhawulo wenzuzo ye-bisphenol A ube uphansi uma kuqhathaniswa, umdlandla wabalamuli wokubamba iqhaza unciphile, kanye nenani lemikhiqizo edayiswayo lehlile.Njengamanje, azikho izinsiza eziningi ezitholakala emakethe ye-bisphenol A, futhi abanikazi abazimisele ukuthengisa, okubonisa inhloso ephezulu yokuphusha.

Ngasohlangothini olungezansi komfula, kusukela ngo-2023, ukutholwa kwesidingo setheminali esezansi nomfula kube ngaphansi kakhulu kunalokho obekulindelwe, futhi ukugxila kwe-epoxy resin kanye nezimakethe ze-PC nakho bekubuthakathaka futhi kuguquguquka.I-Bisphenol A isetshenziselwa kakhulu ukugcina ukusetshenziswa kwenkontileka, futhi abambalwa badinga nje ukuthenga ngentengo efanelekile.Umthamo wokuhweba wama-oda wezindawo unqunyelwe.Njengamanje, izinga lokusebenza lemboni ye-epoxy resin lizungeze i-50%, kanti imboni ye-PC iseduze ne-70%.Muva nje, i-bisphenol A kanye nemikhiqizo ehlobene ne-ECH yenyukile ngasikhathi sinye, okuholele ekwenyukeni kwezindleko ze-epoxy resin kanye nokwenyuka okuncane kokugxila emakethe.Kodwa-ke, bekumbalwa ukusebenza kwesitokwe esingaphansi komfula kwe-PC ngaphambi koSuku lukaMeyi, futhi izingcindezi zokuhlinzekwa kwemboni kanye nezimfuno zisekhona.Ngaphezu kwalokho, i-bisphenol A eluhlaza iyaqhubeka nokukhuphuka ngamandla, ngezingxabano zokuhlinzeka nezidingo kanye nezingcindezi zezindleko.Amabhizinisi ngokuyinhloko azinzile futhi azinzile futhi alinde futhi abone, futhi ukuthengwa kwezidingo ezingezansi akwanele, okuholela ekuhwebeni kwangempela okuyindlala.
Ngasekupheleni kwenyanga, akukho ngcindezi ekuthuthweni kwempahla, futhi ingcindezi yezindleko isekhona.Umnikazi wezimpahla unenhloso eqinile yokuphusha.Yize kuqaphile uma kuqhathaniswa ukuphishekela amanani aphezulu ezansi nomfula, ikakhulukazi okuthenga ngokufunwa, kunzima ukuthola inani eliphansi emakethe, futhi ukugxila kwemakethe ye-bisphenol A kuya kumanani aphezulu.Kulindeleke ukuthi i-Bisphenol A iqhubeke nokuba nokuguquguquka okuqinile futhi inake ukulandelwa kwesidingo esingezansi.
