I-Pyromellitic dianhydride(PMDA) yinkomponi enemisebenzi emininzi edlala indima ebalulekileyo ekuphuhliseni i-polyimide resins ekwazi ukumelana nobushushu, iifilim, kunye nezaleko.Iimpawu zayo ezikhethekileyo ziyenza ibe yinto eyimfuneko ekrwada kwiintlobo ngeentlobo zezicelo eziphezulu zokusebenza, ukusuka kwiibhodi zesekethe eziguquguqukayo eziprintiweyo ukuya kwi-enameled wire insulation.Makhe sijonge ngakumbi ukubanakho kwe-PMDA kunye nefuthe layo kushishino.
I-PMDA ingundoqo ophakathi kwimveliso yeefilimu ze-polyimide, ezaziwa ngokuzinza kwazo okuphezulu kwe-thermal kunye namandla omatshini.Ezi bhanyabhanya zisetyenziswa ngokubanzi kwiibhodi zesekethe eziguquguqukayo eziprintiweyo kwaye zinokuthumela imiqondiso yombane ngaphandle komthungo ngelixa imelana nobushushu obuphezulu.Ukongezelela, iifilimu ze-PMDA ezisekelwe kwi-polyimide ziyinxalenye yeeteyiphu zokuzibamba, inkqubo ephambili yokuhlanganisa amacandelo e-elektroniki.
Ukongezelela, i-PMDA inceda ekuqulunqweni kwee-polyimide-based composites, ukuphucula iimpawu zabo ze-thermal kunye ne-mechanical.Ezi mbumba zikwimfuno ephezulu yokukwazi ukumelana neemeko zokusebenza eziqatha, zizenza zilungele ukusetyenziswa kwe-aerospace, i-automotive kunye ne-electronics.I-PMDA-based polyimide composites inokumelana nokushisa okukhulu kunye nokuzinza kwe-dimensional, okwenza kube yinto yokuqala yokukhetha kwiindawo apho izinto zemveli zingonelanga.
Kwintsimi ye-enameled wire insulation, i-PMDA idlala indima ebalulekileyo ekuqinisekiseni ixesha elide kunye nokuthembeka kweenkqubo zombane.Ngokubandakanya i-PMDA kwizinto zokugquma, abavelisi banokudala iingcingo ezinokumelana namaqondo okushisa agqithisileyo kunye neendawo ezibuhlungu.Oku kubaluleke kakhulu kumashishini afana nokuvelisa umbane, apho imfuno yezisombululo ezisebenza ngokuphezulu zibalulekile.
Ukongeza, i-PMDA iququzelela uphuhliso lweengubo ezikumgangatho ophezulu ezinokumelana ne-thermal kunye nokungangeni kweekhemikhali.Ezi zogquma zineendlela ezahlukeneyo zokusetyenziswa, ukusuka ekukhuseleni izixhobo zoshishino kwiindawo ezinobushushu obuphezulu ukubonelela ngezigqibo ezihlala zihleli kwi-electronics yabathengi.Iingubo ezisekelwe kwi-PMDA ziyakwazi ukugcina ingqibelelo yazo phantsi koxinzelelo, zibenza zibe yimpahla ebalulekileyo kwiindidi ezahlukeneyo zamashishini.
Njengoko amashishini eqhubeka nokutyhala imida yokusebenza kunye nokuthembeka, imfuno ye-PMDA kulindeleke ukuba inyuke.Idlala indima engenakulinganiswa ekuveliseni izinto eziphambili ezisebenza kwiimeko ezinzima.I-PMDA's versatility ekwandiseni i-thermal kunye ne-mechanical properties yeemveliso ze-polyimide igxininisa ukubaluleka kwayo ekuqhubeni izinto ezintsha kumashishini amaninzi.
Isishwankathelo, i-pyromellitic dianhydride (PMDA) ilitye lembombo lokuphuhliswa kwezinto eziphezulu zokusebenza kunye nokuchasana kwe-thermal kunye nokunyaniseka komatshini.Impembelelo yayo ivakala kuwo wonke amashishini ukusuka kwi-electronics ukuya kwi-aerospace, apho imfuno yezisombululo ezithembekileyo nezizinzileyo zingenakuxoxisana.Njengoko uphando kunye nophuhliso luqhubeka, i-PMDA ilindeleke ukuba iqhubeke ukuba yi-catalyst ye-innovation kunye nokubumba ikamva lezicelo eziphezulu zokusebenza.
