Puas yog polyimide zaj duab xis tiv taus qhov kub thiab txias?

Polyimide zaj duab xis yog ib hom tshiab ntawm kub resistant organic polymer zaj duab xis, uas yog tsim los ntawm pyromellitic dianhydride (PMDA) thiab diaminodiphenyl ether (ODA) nyob rau hauv ib tug muaj zog heev hnyav dimethylacetamide (DMAC) nruab nrab condensation thiab salivation yog tsim, thiab ces imidization yog nqa. tawm. Nws yog qhov ua haujlwm zoo tshaj plaws nyias-zaj duab xis insulating khoom nyob hauv lub ntiaj teb thiab muaj lub zog zoo heev. Kev ua haujlwm hluav taws xob, tshuaj lom neeg ruaj khov thiab hluav taws xob tiv thaiv hluav taws xob, siab kub thiab kub tsis kam (-269 ~ + 400 ~ C).
