Polymides (pi) ke li-polymmers tsa ts'ebetso e phahameng tsa tlhaho tse nang le li-nitrogen tse peli tse nang le li-Netrojene tse peli (n) tse nang le li-acyl tse peli (c = o). Li-polymers tsena li tsebahala ka 'mele oa tsona o phahameng oa mocheso o tsoang ho 400-500 ° C.
Lits'ebetso tse ngata tsa indasteri, li sebelisetsoa ho sebelisa khalase ea mofuta, tšepe esita le tšepe.
Polyimides e na le thepa e ntle ea ho aka ebile e ka sebelisoa likopo tse hlokang lisebelisoa tse matla tsa manyolo, mohlala:
Lisele tsa mocheso o phahameng
Lits'oants'o tsa Panel Flat
Lisebelisoa tsa Aerospace
Liindasteri tsa lik'hemik'hale le tikoloho
le likopo tse fapaneng tsa sesole
Li sebelisoa e le polasetiki, lifilimi, litloana le mabenkele le mabelo a mocheso a phahameng haholo.
Polyimides e fumaneha ka mefuta e 'meli: Thermoset le Thermoplane.
PI e ka aroloa ka therekotetsong le Thermoplanet, e ka aroloa ka boema-kepe (TETramethylene tetacarbimide), polyemide khono
PMMI ka 1.8 MPA e kenya mocheso o sokolla mocheso oa 360 ℃, mocheso o motle oa motlakase, litiiso, li ka sebelisoa ho ikopanya le ammonia e nang le metsi dikarolo tsa li-valve, enjene ea jese ea jete ea letsoai
Pei o na le thepa ea matsoho e phahameng haholo ea ho fana ka maikutlo sebelisoa bakeng sa mekhoa e itseng e jang le lisebelisoa tse ling tse kopantsoeng le lisebelisoa tsa motlakase le lisebelisoa tsa motlakase, aerospace, lisebelisoa tsa bongaka le liindasteri tsa bongaka li sebelisoa haholo.
Matla a Pai ke a phahameng ka ho fetisisa lipolelong tse seng tsa morao-rao, matla a mabenyane ke a 140 mpa, 'me mocheso o qholotsang o phahame joalo ka 274 ℃ ka tlasa mojaro oa 1,8 mpa. Pai o na le khanyetso e ntle ea thupelo ea kothahelo le maqhubu a motlakase a phahameng le lisebelisoa tse ling haholo-holo tsa mechini e arolang ea lifoto, jj., Le E ka sebelisoa bakeng sa thepa e mafolofolo ea lifofane, lisebelisoa tse ling tsa transpenda, 'me li ka sebelisoa tlhahiso ea lisebelisoa tsa elektroniki. E sebelisoa haholo ka leeba, likopano le likhoele tse arohanyang tsa baqapi, jj.
