ethula:
Emkhakheni wezinto ezithuthukisiwe,i-pyromellitic dianhydride(PMDA) isichume njengesithako esibalulekile ekwakhiweni kwezinsalela ze-polyimide ezingashisi, amafilimu kanye nezimbozwe.Ngokuzinza kwayo okuhle kakhulu kokushisa nokuguquguquka, i-PMDA isibe yisinqumo sokuqala sezinhlelo zokusebenza eziningi ezisebenza kahle kakhulu.Kule bhulogi, sihlola amandla amakhulu ama-PMDA kanye neqhaza lawo ekuguquleni izimboni ezihlukahlukene.
Ukumelana Nokushisa Okungapheli:
I-PMDA inokumelana nokushisa okuhle kakhulu futhi iyimpahla eluhlaza efanelekile yokukhiqiza amafilimu e-polyimide.Lawa mafilimu asetshenziswa kakhulu kumabhodi esekethe aphrintiwe aguquguqukayo, i-tape yokubopha othomathikhi kanye nokufakwa kwentambo kazibuthe.Ngokuhlanganisa i-PMDA, lezi zinto zokusebenza zingakwazi ukumelana namazinga okushisa adlulele ngaphandle kokudela ubuqotho bazo besakhiwo.Kuzinhlelo zokusebenza lapho ukufakwa kwe-thermal kubaluleke kakhulu, amafilimu e-PMDA-based polyimide anikeza ukusebenza okungenakuqhathaniswa.
I-Powerpack Composites:
I-PMDA iphinde ibe neqhaza elibalulekile ekwakhiweni kwezinhlanganisela ezisuselwe ku-polyimide.Lezi zinhlanganisela zihlanganisa ukumelana nokushisa okuphezulu kwe-polyimide namandla kanye nezakhiwo ezingasindi zezinye izinto.Ngenxa yalokho, izimboni ezifana ne-aerospace, ezezimoto kanye ne-electronics ziyazuza ekuthuthukisweni kwezingxenye ezisebenza kahle kakhulu.Kungakhathaliseki ukuthi ukukhiqiza izingxenye zezindiza noma ukuthuthukisa ukuqina kwemishini kagesi, izinhlanganisela ezisekelwe ku-PMDA zinikeza isisombululo esiyimpumelelo.
I-Hardener:
Ngaphezu kwendima yayo kuma-polyimide resins, i-PMDA ingasetshenziswa futhi njenge-ejenti yokwelapha ama-epoxy resins kuma-powders okubumba.Uhlelo lokusebenza luvumela ukwakhiwa kwezingxenye ezikhethekile ezifana nezindandatho zophawu, amawasha ama-thrust, ama-spacers nama-insulators.Ngokungeza i-PMDA njenge-ejenti elaphayo, i-epoxy resin ingathuthukisa izakhiwo ezishisayo nezomshini, ngaleyo ndlela ithuthukise ukusebenza kwayo konke futhi yandise ububanzi bokusebenza kwayo.
Innovation Roadmap:
Izici ezinhle kakhulu ze-PMDA ziyenza ibe yisithako esibalulekile ekuphishekeleni ukuqamba okusha.Izimboni zithembele ekhonweni layo eliyingqayizivele lokumelana nezinga lokushisa eliphezulu ukuze ziqinisekise ukuphepha nokwethembeka kwemikhiqizo yazo.Ngokuphusha imingcele yokumelana nokushisa, ama-PMDA avula amathuba amasha entuthuko ku-electronics, i-aerospace, neminye imikhakha lapho ukunemba nokuthembeka kubaluleke kakhulu.
Ekuphetheni:
I-Pyromellitic dianhydride (PMDA) iwushintsho lwangempela lomdlalo emkhakheni wezinto ezithuthukisiwe.Ukumelana nokushisa kwayo okuhle kakhulu kanye nokuguquguquka kwayo kuyenza ibe isithako esibalulekile ekukhiqizweni kwama-polyimide resins, amafilimu nezinhlanganisela.Njengoba izimboni zilwela ukuqamba izinto ezintsha nokuthembeka, i-PMDA ihlinzeka ngesisekelo esidingekayo ukuze kuqhutshekwe nemingcele yokumelana nokushisa.Njengoba i-PMDA iphethe izintambo, singalindela ukubona intuthuko enkulu ezinhlelweni zokusebenza ezisebenza kahle kakhulu, okuqinisekisa izinga eliphezulu nokuphepha eminyakeni ezayo.
