Izingxenye ze-polymide ze-polymide gaskets ezimisiwe

I-PolYimide ingenye yokusebenza okungcono kokusebenza okungcono kwezinto eziphilayo ze-polymer, ukumelana okuphezulu kwamazinga okushisa okungaphezulu kwama-400 ℃, ukusetshenziswa kwesikhathi eside kwamazinga okushisa -200 ~ 300 ℃, akukho phuzu eliphambili lokuncibilika, i-103 hz dielectric, , Ukulahleka kwe-dielectric kwe-0,004 ~ 0.007 engu-0,007, okungu-F ku-H ku-H A ku-H Izilinganiso Zezinto Zokufakelwa.

Ngokwesakhiwo samakhemikhali seyunithi ephindaphindwayo, i-polymide ingahlukaniswa ibe yi-polyomide e-aliphatic, enamakha amnandi futhi amnandi. Ngokwezakhiwo ezishisayo, zingahlukaniswa nge-thermoplastic ne-thermosetting polyomide.

Izici ze-Polyimide Gasket:

I-1, i-polymide inokuphikiswa okuphezulu kwe-irradiation, ifilimu yayo ku-5 × 109rad okusheshayo kwe-elektroni yokuqoshwa kwamandla okugcinwa kwamandla ka-90%.

2, i-polymide inezindawo ezinhle ze-dielectric, i-dielectric ihlala i-3.4 noma kunjalo, ukwethulwa kwe-fluorine, noma usayizi we-air nanometer ahlakazeka ePolymide, i-dielectric njalo ingancishiswa yaba ngu-2,5. Ukulahleka kwe-dielectric kwama-10-3, ama-dielectric amandla we-100-300kv / mm, i-geangcheng thermoplastic polyoplide ye-300kv / mm, ukumelana kwevolumu kwe-1017 ω-cm. Lezi zakhiwo ezisezinhlangeni eziningi zamazinga okushisa kanye nobubanzi bokujwayelekile zisagcinwa ezingeni eliphakeme.

I-3, i-polymide iyi-polymer yokuzicishanisa, izinga lokufutheka okuphansi, alishisi.

I-4, polymide endaweni ephakeme ngaphansi kwenani lokuphuma lincane kakhulu.

I-5, i-polymide non-anobuthi, ingasetshenziselwa ukwenza amathuluzi we-turview kanye nezokwelapha, futhi ibekezelele izinkulungwane zezikhathi zezikhathi ezithile. Kukhona amanye ama-polyomide anakho ukufana okuhle kakhulu, ngokwesibonelo, ekuhlolweni kokuhambisana kwegazi kwe-non-hemolytic, ekuhlolweni kwe-vitro cytotoxity for non-active.
