Iithegi zeMveliso

I-BDFA isetyenziswa ngokubanzi njengenxalenye ebalulekileyo ekudityanisweni kweepolymers ezisebenza kakhulu kunye nemathiriyeli.Isakhiwo sayo esikhethekileyo semolekyuli, esiquka amakhonkco amabini e-benzene ancanyathiselwe kwi-fluorene backbone, ibonelela ngeempawu ezikhethekileyo zobushushu kunye nezomatshini kwiipolymers ezibangelwayo.

Uzinzo olukhethekileyo lwe-thermal ye-BDFA-based polymers lubavumela ukuba bamelane namaqondo obushushu aphezulu, okwenza ukuba bafanelekele ukusetyenziswa kwi-aerospace, i-automotive, kunye ne-electronics industry.Ezi polima zibonisa ukuxhathisa okumangalisayo kubushushu, imitha ye-UV, kunye nokubola kweekhemikhali, iqinisekisa ubomi babo obude kunye nokuqina kwiindawo ezibango.

Ngaphaya koko, iipolima ezisekwe kwi-BDFA zineempawu ezibalaseleyo zokugquma umbane, zizenza zibe lolona khetho lufanelekileyo kusetyenziso lombane nolwe-elektroniki.Ezi polymers zingasetyenziselwa ukuveliswa kwee-insulators, amacandelo e-elektroniki, kunye neebhodi zeesekethe eziprintiweyo, apho ukuhanjiswa kombane kufuneka kuncitshiswe.

I-BDFA idume ngokukwazi kwayo ukomeleza amandla oomatshini kunye nokuqina kweepolima.Ngokubandakanya i-BDFA kwimatriki yepolymer, izinto ezifunyenweyo zibonisa ukomelela okuphuculweyo, ukuchasa impembelelo, kunye nokuzinza komda.Oku kubenza balungele izicelo kumashishini okwakha, eemoto, kunye nempahla yabathengi.

Ukongeza kwizicelo zayo kwiipolymers ezisebenza kakhulu, i-BDFA ifumana into eluncedo ekuveliseni iikhemikhali ezikhethekileyo, idayi, kunye nebala.Ubume bayo obukhethekileyo bemolekyuli bubonelela ngamathuba okwenziwa ngokwezifiso, ukuvumela abaphandi kunye nabavelisi ukuba baphuhlise izinto ezintsha ezineempawu ezilungiselelweyo.
