9,9-Bis(3,4-dicarboxyphenyl)fluorene Dianhydride/BPAF cas:135876-30-1
I-BDFA isetshenziswa kabanzi njengengxenye ebalulekile ekuhlanganiseni ama-polymers asebenza kahle kakhulu nezinto zokwakha.Isakhiwo sayo samangqamuzana esiyingqayizivele, esihlanganisa izindandatho ezimbili ze-benzene ezixhunywe kumgogodla we-fluorene, sinikeza izici ezishisayo ezingavamile kanye nemishini kuma-polymers avelayo.
Ukuzinza okushisayo okukhethekile kwama-polymers asekelwe ku-BDFA kuzivumela ukuthi zimelane namazinga okushisa aphezulu, okuwenza afanelekele ukusetshenziswa ezimbonini ze-aerospace, zezimoto, neze-electronics.Lawa ma-polymers akhombisa ukumelana nokushisa okumangalisayo, emisebeni ye-UV, nokugqwala kwamakhemikhali, okuqinisekisa ukuphila kwawo isikhathi eside nokuqina ezindaweni ezidinga kakhulu.
Ngaphezu kwalokho, ama-polymers asuselwa ku-BDFA anezakhiwo ezinhle kakhulu zokufakwa kukagesi, okuwenza abe yinketho efanelekile yezicelo zikagesi neze-elekthronikhi.Lawa ma-polymers angasetshenziswa ekwenziweni kwama-insulators, izakhi ze-elekthronikhi, namabhodi wesekethe aphrintiwe, lapho ukuqhutshwa kukagesi kudinga ukuncishiswa.
I-BDFA iphinde yaziwe ngamandla ayo okuthuthukisa amandla emishini kanye nokuqina kwama-polymers.Ngokuhlanganisa i-BDFA kumatrices e-polymer, izinto ezisetshenziswayo eziwumphumela zibonisa amandla athuthukisiwe aqinile, ukumelana nomthelela, nokuzinza kwe-dimensional.Lokhu kubenza bafanelekele izicelo embonini yokwakha, yezimoto, nempahla yabathengi.
Ngokungeziwe ekusebenziseni kwayo kuma-polymers asebenza kahle kakhulu, i-BDFA ithola usizo ekukhiqizeni amakhemikhali akhethekile, odayi, nezingulube.Isakhiwo sayo samangqamuzana esiyingqayizivele sinikeza amathuba okwenza ngokwezifiso, okuvumela abacwaningi nabakhiqizi ukuthi bakhe izinto ezintsha ezinezici ezihambisanayo.
