Muva nje, intengo ye-bisphenol A iphinde yakhuphuka isuka ezingeni eliphansi. Yize lezi zimboni ezimbili ezansi nomfula ziqala ukuba ngcono, izinga lokuqala le-epoxy resin elicishe libe ngu-50%, izinga lokuqala le-PC elingu-60% ngaphezulu, kodwa i-bisphenol A ukuze kugcinwe ukusetshenziswa kwenkontileka noma ukuphathwa kwempahla, inani elincane labantu abangashadile lidinga nje ukungena emakethe ukuze lithenge, i-bisphenol A amandla okuthengiswa kwemakethe alanele, isikhungo sokuxoxisana sibe nzima ukuthola i-gravi.

Nakuba intengo ye-phenol ketones ekhuphukayo iguquguquka, kodwa izindleko ze-BPA zinomthelela omncane emakethe. Njengoba intengo yemakethe yehla yaba sezingeni eliphansi, umthelela wokuzimisela okuphansi kwabanikazi bamasheya kancane kancane waqala ukuba buthaka, okuhambisana nokuphathwa kohlu lokusalela emuva kwebhizinisi kancane kancane kwathuthukiswa futhi kwasetshenziswa, amathuba aphansi okubuyisela emakethe ayancipha, izinhloso zabaxhumanisi zokunyusa intengo. Kodwa-ke, uhlangothi lwesidingo aluzange lube ngcono okusobala, i-bisphenol A ibe yinkinga lapho ubhekene nesimo, kusukela ngo-Agasti 3, imakethe yezomnotho yaseMpumalanga yeChina i-bisphenol A imikhiqizo evamile inikeza phakathi kuka-11,800-12,000 yuan / ton, okujwayelekile ukugcina ikhono lokuxoxisana phakathi kwe-11,800n yuan / 11.

I-Bisphenol A August iyonke yokuhlaziya ukuthuthukiswa:

Uhlangothi lokuhlinzekwa kwempahla: Ngo-August ukukhiqizwa kwasekhaya kwe-bisphenol A ngenani elilinganiselwe lamathani angu-194,000, uma kuqhathaniswa noJulayi 184,600 amathani phakathi kokukhuphuka kwamathani ayizigidi ezingu-0.94, noma u-5.09%. Nakuba isilinganiso sokuqala se-bisphenol A phakathi kwamaphesenti angu-70, futhi maphakathi no-Agasti amasethi amabili emishini ehlelelwe ukushintshwa, futhi i-Cangzhou Dahua amathani angu-200,000 / ngonyaka i-bisphenol A ibekwe icala ekupheleni kukaJulayi, kulindeleke ukuthi iphume ngo-August emkhiqizweni, kuhlanganiswe ne-Zhejiang Petrochemical Phase II, i-Pingi iqale kabusha i-Shenzhou I-Zhongxin isanda kuqalisa kabusha izinhlelo, ukunikezwa kwasekhaya kuzokwenyuka uma kuqhathaniswa noJulayi; ukungenisa, kucatshangelwa izici eziningi, ngaphezulu Gcina inkontileka thatha ikakhulukazi, umthamo wokungenisa uzinzile. Ngakho-ke, ukunikezwa kwasekhaya kwe-BPA kuzokhuphuka kancane ngo-Agasti.

Uhlangothi lwesidingo: Njengamanje, ukulayisha kwe-epoxy resin engezansi komfula kusondele kumaphesenti angamashumi amahlanu, ngo-Agasti kunengxenye yedivayisi yomsebenzi ukuphakamisa amadivayisi angalungile namasha afakwe esivivinyweni sokusebenza, enye i-PC ebalulekile ephansi yonkana yobunjiniyela iqala ukulayisha ngo-60% kancane, ngo-Agasti ingxenye yohlelo lwedivayisi yokulawula iqala kabusha noma iphakamisa i-negative, ezimbili ezansi ngo-August umthwalo wokuqalisa ibhizinisi uzoba ukwanda okuncane. Nakuba ezimbili zamanje ezansi nomfula ziwukugcina ukusetshenziswa kwenkontileka ye-bisphenol A okugxile ebhizinisini, inani elincane lesidingo nje sokungena emakethe ukuze kuthengwe, ukuhweba ngamabala kulula, kodwa ukusetshenziswa okuphelele kwezinkinga ze-bisphenol A kubonisa umkhuba okhulayo.

Uhlangothi lwenzuzo: kusukela ngoJulayi, i-benzene emsulwa enokuguquguquka okuvamile kuwoyela ongahluziwe, i-upstream phenone nayo ithintwa izindleko nesidingo sokuhlaziywa kwemakethe phezulu naphansi ngokuphindaphindiwe, ukuguquguquka kokulawulwa kwezindleko ze-BPA ekuthuthukisweni kokuguquguquka kwenzuzo iyonke yebhizinisi lemboni phakathi kuka-1000, umnotho uwonke uphansi uma kuqhathaniswa. Uma kucatshangelwa amamajini ezindleko, amanani emakethe ye-BPA afinyelele izinga eliphansi lokumelana namanani, ngakho abanikazi be-BPA abazimisele kangako ukwehlisa amanani.

Ukunikezwa kwemakethe ye-BPA yango-August kukhule kancane, kwavimbela ukukhula komnotho ukusetshenziswa kwezinkampani ezansi nomfula, kanye nesakhiwo sokuhlinzekwa kwezinsizakalo kanye nesidingo sashintsha ngokuthula. Futhi i-phenol ketone ekhuphukayo iguquguquka ngokuphindaphindiwe, indawo yonke ngo-Agasti izinguquko zincane, ukusekelwa kwe-BPA yezindleko zokucindezela kusekhona, ukukhathazeka mayelana nesistimu yedivayisi yasekhaya emibili phakathi nasekupheleni konyaka ngemva kokugcinwa okulandelanayo kokuhlinzekwa komnotho wemakethe kanye nokufuna ukushintshashintsha kwezindaba ekuthuthukisweni.
