Ifilimu ye-Polymimide (i-polyoindoidefilm) ekubhekiswa kuyo njengefilimu ye-PI yindawo yokugcina ifilimu ngokusebenza kakuhle. Yenziwe ngePyromellitic Dianhydride (PMDA) kunye ne-DEAINDODPE ETERE (DDE) ngokusebenzisa i-Polymerization iphoswa kwifilimu kwaye ihlawulwe.

Amanqaku: I-Bline kunye neNgcali, i-Demonity 1.39 ~ 1.45, ifilimu yombane ifanelekile, kwaye inokusetyenziswa kwi-1,29 ° C ° C ° I-CY ingaba isetyenzisiwe Ixesha elide kuluhlu lobushushu, kwaye linokufikelela kubushushu obuphezulu onama-400 ° C ngexesha elifutshane. Amaqondo obushushu eglasi angama-280 ° C (i-pupilex R), i-385 ° C (Kapton) nangaphezulu kwe-500 ° C (i-Cupilex s). Amandla obuzinile yi-200MPA nge-20 ° C kwaye ngaphezulu kwe-100MPA nge-200 ° C. Ibaluleke ngokukodwa njengeziko lesekethe eliguqulelweyo eliprintwe kunye nezinto ezifakiweyo ze-subring iimotor ezingathandekiyo kunye nezixhobo zombane.

Izibonelelo zoPolimide

(1) Ukumelana nobushushu obuhle. Iqondo lokushisa le-Polymimide lingaphezulu kwe-500 ° C, ngamanye amaxesha ngaphezulu, kwaye yenye yeentlobo zokuzinza okuphezulu kwe-thelymer ephakathi, ikakhulu kuba i-molecular iqulethe inani elikhulu le-molematic.

(2) Iimpawu ezibalaseleyo zoomatshini. Amandla e-sunsed onnrix yeMatrix engaphezulu kwe-100MPA. Amandla e-thapton yefilimu elungiselelwe i-HomoanDDDride i-170MPA, ngelixa i-biphenyl polylimide (i-biilex s) inokufikelela kwi-400MPA. Imowudi ye-elastic ye-fiber ye-pollimide inokufikelela kwi-500MPA, yesibini kuphela kwi-carbon fiber.

(3) Ukungazinzi kwekhemikhali kunye nobushushu kunye nokunganyangeki komswakama. Izinto zePolymide ngokubanzi zingena nzombulo, zichasene nokungavisisani, kunye ne-hydrolysis. Iintlobo ngeentlobo ezinamaziko awahlukeneyo zinokufumaneka ngokutshintsha uyilo lwemolekyuli. Ezinye iintlobo zinokukhusela ukubila nge-120 ° C i-500 iiyure kwi-2 ye-2.

(4) Ukunganyangeki kwe-radiation elungileyo. Amandla efilimu yepolimide ihlala i-86% emva kwe-5 × 109rad imitha yedosi; Ezinye iintsinga zepolimide zigcina iipesenti ezingama-90 zamandla azo emva kwe-1 × 1010rad ekhawulezayo.

(5) Iipropathi ezilungileyo zeDiectoric. I-Delectric rhoqo ingaphantsi kwe-3.5. Ukuba iiathom ze-fluorine zisiwe kwi-molecular thein, i-dielectric rhoqo inokuncitshiswa ibe yi-2,5, ilahleko ye-dielectric yi-1000kv / i-300KV / mm, kwaye ukunyangwa kwevolumu yi-1015-17ωm. Ke ngoko, i-synthesis ye-fluorine-enezinto ze-polyorines yintsimi yophando eshushu.
