Movie ea Polyimide (Polyimidefilm) e fetisetsoa ha filimi ea PI ke thepa e tšesaane ea lifilimi ka ts'ebetso e ntle. E entsoe ka li-pyromellitic dianhydride (pmda) le Diamidorony ether (dde) ka mokhoa o boima.

Likarolo tsa: Boraro-bo-bong le boselang, ba nang le likhoele tsa motlakase, ho hanyetsa mahlaseli, ho hanyetsa, ho hanyetsa, ho hanyetsa, ho hanyetsa - ho hana Ka nako e telele khaolong ea mocheso, 'me e ka fihla mocheso o phahameng oa 400 ° C ka nako e khuts'oane. Temple ea khalase ea khalase ke C (inilex R), 385 ° C (Kapton) le ka holim'a 500 ° C (Oneilex s). Matla a futhumetseng ke 200Le matla a ho 20 ° C le baholo ho feta 100mpa ka 200 ° C. E loketse haholo e le karolo ea potoloho e nang le maemo khafetsa le lisebelisoa tsa ho lekola lisebelisoa tse fapaneng tse thata mocheso o monyetsang le lisebelisoa tsa motlakase.

Melemo ea polyimide

(1) Ho hanyetsa ho futhumatsa mocheso haholo. Mefokolo ea ho bolaoa ha polyimipi e feta 500 ea C, ka linako tse ling ke botsitso bo phahameng ba polymers tse tsebahalang, haholo-holo kemiso e kholo.

(2) LITLHAKISO TSE KHOLO TSE KHOLO TSE LING. Matla a sa tsitsang a thepa ea matrix ea sa sebetseng a kaholimo ho 100Ma. Ho na le matla a hopton a lokiselitsoeng le Homoanhydride ke 170Ma, ha Biehenyl Polyimide (inilex s) e ka fihlela 400mpa. Mofumahali oa Elastics oa Polymimide Fiber o ka fihla 500Ma, oa bobeli ke khabone ea khabone ea khabone.

(3) botsitso ba lik'hemik'hale tse ntle tsa lik'hemik'hale le khatello ea maikutlo le mongobo. Lisebelisoa tsa polyimide hangata ha li khanyetsehe ka thata lithupa, li-corrolys-esistant, le hydrolysis e thibelang. Mefuta e mengata e nang le meaho e fapaneng e ka fumanoa ka ho fetola moralo oa limokek'hule. Mefuta e meng e ka ema e belang e belang ka lihora tse 120 ° C bakeng sa lihora tse 500 ho 5 Amatesphera.

(4) Ho hanyetsa hantle radiation. Matla a filmimide filmide e lula e le 86% kamora 5 × 109rad Case mahlaseli a 5; Likhoele tse ling tsa polyimide li boloka 90% ea matla a bona kamora 1 × 1010rad radiation ea Electron.

(5) thepa e ntle ea lefu la liketsahalo. Deectactric Constant e ka tlase ho 3.5. Haeba liathomo tsa fluorne li hlahisoa ka kemiso ea limolek'hule, Concentric e ka fokotsoa hoo e ka bang 10, matla a Dialectric ke 100 ho 300Kv / mm, 'me ho hanyetsa. Ka hona, li-synthes tsa phooki e nang le frurimide - ke lebala le chesang la ho lipatlisiso.
