I-Pyromellitic dianhydride(PMDA) iyinhlanganisela enemisebenzi eminingi edlala indima ebalulekile ekwakhiweni kwezinsalela ze-polyimide ezingashisi ukushisa, amafilimu, nezimbozo.Izakhiwo zayo ezihlukile ziyenza ibe impahla eluhlaza engadingeki ezinhlelweni zokusebenza ezihlukahlukene, kusukela kumabhodi esekethe aphrintiwe aguqulekayo kuye kokufakwa kwezintambo ezinoqweqwe lwawo.Ake sibhekisise amandla e-PMDA kanye nomthelela wayo embonini.
I-PMDA iwukhiye omaphakathi ekukhiqizweni kwamafilimu e-polyimide, aziwa ngokuzinza kwawo okuhle kakhulu okushisayo namandla emishini.Lawa mafilimu asetshenziswa kakhulu kumabhodi esekethe aphrintiwe avumelana nezimo futhi angadlulisela amasignali kagesi ngaphandle komthungo kuyilapho emelana namazinga okushisa aphezulu.Ngaphezu kwalokho, amafilimu e-PMDA-based polyimide ayizingxenye zamateyipu azinamathelayo, inqubo eyinhloko yokuhlanganisa izingxenye ze-elekthronikhi.
Ukwengeza, i-PMDA isiza ekwakhiweni kwezinhlanganisela ezisuselwe ku-polyimide, ithuthukise izakhiwo zayo ezishisayo nezomshini.Lezi zinhlanganisela zidingeka kakhulu amandla azo okumelana nezimo zokusebenza ezinzima, okuzenza zilungele ukusetshenziswa kwe-aerospace, izimoto kanye ne-electronics.Izinhlanganisela ze-polyimide ezisekelwe ku-PMDA zinokumelana nokushisa okuhle kakhulu nokuzinza kobukhulu, okuzenza zibe yinketho yokuqala ezindaweni lapho izinto zendabuko zinganele.
Emkhakheni wokufakwa kwezintambo ezinoqweqwe oluqinile, i-PMDA idlala indima ebalulekile ekuqinisekiseni ukuphila isikhathi eside nokuthembeka kwezinhlelo zikagesi.Ngokuhlanganisa i-PMDA ezintweni zokufakelwa, abakhiqizi bangakha izintambo ezikwazi ukumelana nezinga lokushisa elidlulele kanye nezindawo ezinokhahlo.Lokhu kubaluleke kakhulu ezimbonini ezifana nokuphehla ugesi, lapho isidingo sezixazululo ezisebenza kahle kakhulu zokuhlanganisa sibalulekile.
Ukwengeza, i-PMDA isiza ukuthuthukiswa kwezingubo ezisezingeni eliphezulu ezinokumelana nokushisa okuhle kakhulu kanye nokungangeni kwamakhemikhali.Lezi zinhlobonhlobo zinezinhlelo zokusebenza ezihlukahlukene, kusukela ekuvikeleni imishini yezimboni ezindaweni ezisezingeni lokushisa eliphezulu ukuya ekuhlinzekeni okuhlala isikhathi eside kwama-electronics abathengi.Izembatho ezisekelwe ku-PMDA ziyakwazi ukugcina ubuqotho bazo ngaphansi kwengcindezi, zizenze zibe izimpahla ezibalulekile kuzo zonke izimboni ezihlukahlukene.
Njengoba izimboni ziqhubeka nokuphusha imingcele yokusebenza nokuthembeka, isidingo se-PMDA kulindeleke ukuthi sikhuphuke.Idlala indima engenakuqhathaniswa ekukhiqizeni izinto ezithuthukisiwe ezisebenza ezimweni ezimbi kakhulu.Ukuguquguquka kwe-PMDA ekuthuthukiseni izici ezishisayo nezokusebenza zemikhiqizo ye-polyimide kugqamisa ukubaluleka kwayo ekuqhubekiseni ukuqanjwa kabusha kuzo zonke izimboni eziningi.
Kafushane, i-pyromellitic dianhydride (PMDA) iyisisekelo sokuthuthukiswa kwezinto ezisebenza kahle ezinokumelana okuhle kakhulu kokushisa nobuqotho bemishini.Umthelela wayo uzwakala ezimbonini zonkana kusukela kugesi kuya emkhathini, lapho isidingo sezixazululo ezinokwethenjelwa nezihlala isikhathi eside singenakuxoxisana ngaso.Njengoba ucwaningo nentuthuko iqhubeka, i-PMDA kulindeleke ukuthi iqhubeke nokuba ngumgqugquzeli wokusungula izinto ezintsha futhi ilolonge ikusasa lezicelo ezisebenza kahle kakhulu.
