Filimka Polyimide Insulation - Xakamaynta Waxqabadka Sare ee Ugu Dambeeya ee Deegaanka Ba'an

Sida maadada dahaarka khafiifka ah ee heer caalami ah, filimkeena polyimide (PI) ee dahaarka waxaa lagu sameeyay polycondensation of pyromellitic dianhydride (PMDA) iyo 4,4'-oxydianiline (ODA) ee dareeraha polar ee xooggan, oo ay ku xigto daadinta iyo ka hortagga daaweynta, hubinta tayada gaarka ah iyo xasilloonida inta lagu jiro habka wax soo saarka. Waxay caan ku tahay "filimka dahabka ah" ee is dhexgalka aadka u wanaagsan ee koronto, kulaylka, makaanikada, iyo guryaha kiimikada, taasoo ka dhigaysa shay lagama maarmaanka u ah goobaha farsamada sare.

Filimkeena dahaarka PI wuxuu ku faanaa iska caabin heerkul aad u daran, ilaalinta qaab dhismeedka iyo qaabdhismeedkiisa oo kala duwan laga bilaabo -269 ℃ (-452℉) ilaa 400℃ (752℉), oo leh iska caabin muddo gaaban ah ilaa 500℃, oo la qabsanaya labadaba cryogenic iyo heerkulka sare ee jawi shaqo oo aan dadaal lahayn. Waxay ka kooban tahay wax qabad koronto oo heer sare ah, oo leh awood dielectric ah 100-300kV/mm, dielectric joogto ah oo ah 3.0-3.5 (hoos udhaca 2.5 oo leh wax ka beddelka fluorine), iyo caabbinta mugga 10¹⁵-17Ω · cm, si wax ku ool ah u go'doominaya wareegyada korantada iyo hubinta hawlgalka badbaadada ee qalabka iyo xawaaraha-sare ee tamarta.
