Polyimide fim (polyimidefilm) zoro aka na ya dị ka PI ihe nkiri bụ ihe mkpuchi ihe nkiri dị mma na arụmọrụ dị mma. A na-eme ya nke pyromellatic dianhydride (PMDA) na diminodighenyl ether (DDE) site na polymeriation polymeriation ọ na-abata n'ime fim ma megharịa ya.

Atụmatụ: edo edo na transperent 1.39 ~ 1.45, ihe nkiri polyimation, na-eguzogide, na-eguzogide, na-eguzogide na-eguzogide na -26 ° C Enwere ike iji ya N'ihi na ogologo oge n'ime okpomọkụ okpomọkụ, ma nwee ike iru oke okpomọkụ nke 400 Celsius C na obere oge. Ọkpụkpụ iko ahụ bụ 280 ° C (RELLOX R), 385 Celsius C (KACON) na karịa 500 Celsius C (Worldx s). Ike Tensile bụ 200MPA na 20 Celsius C ma dị ukwuu karịa 100MPA na 200 Celsius C. Ọ dabara adaba dị ka mkpụrụ nke bọọdụ circts na-agbanwe agbanwe na ihe ndị na-eme ka ihe dị iche iche dị elu dị elu na ngwa eletriki.

Uru nke Polymide

(1) ezigbo iguzogide okpomoku. Ọnọdụ ndụ nke polyimide nke Polymimide Oversimide gafere 500 Celsius C, mgbe ụfọdụ elu, ọ bụ otu n'ime ụdị ndị agha a ma ama n'etiti polymon, tumadi na-enwe ọtụtụ mgbaaka dị ukwuu.

(2) Njirimara eji arụ ọrụ. Ike tensile nke ihe matrik matrik na-abụghị 100MPa. Ike Tonsale nke ihe nkiri Kpoton kwadebere na homoanhydride bụ 170MPA, ebe Biphenylylylylylylylylylyl (na-ewuli elu s) nwere ike iru 400MPA. A na-agbanwe agbanwe nke pollimidise fiber nwere ike iru 500MPA, nke abụọ naanị na eriri carbon.

(3) Ezigbo ntuli aka na okpomoku na iru mmiri. Ihe ndị ọzọ na - eme nke ọma na - ekwenyeghi na ha na - eguzogide ntụchi, na hydrolysis-na-eguzogide. Iche iche nwere ike inweta usoro dị iche site na ịgbanwe ihe eji eme ihe. Varietiesfọdụ iche nwere ike iguzogide esi na 120 Celsius C maka awa 500 na elekere abụọ.

(4) ezigbo nguzozi radieshon. Ike nke polyimide fim dị 86% mgbe 5 × 10 × 109rad dose radieshon; Fọdụ polyMide fillers na-ejide 90% nke ike ha mgbe 1 × 1010rad ngwa ngwa electron radieshon.

(5) ezigbo dielectric. The Deelectoric na-erughị 3.5. Ọ bụrụ na a na-ewebata atọm na-ebugharị n'ime akwara, enwere ike belata ihe dị ka 2.5, ike dielectric bụ 10, ike dielectric dị 100 ruo 300kv / mm, na nguzozi ụda bụ 1015-17ω. Ya mere, njikọta nke fluorine-nwere ihe nke polimidide bụ ubi na-ekpo ọkụ.
