Polyimide film inogadzirwa sei?

Kune nzvimbo dzakawanda uko polyimide firimu rinogona kushandiswa. Nokudaro, vatengi vakawanda vanoteerera kune chigadzirwa ichi. Vazhinji vatengi uye shamwari vanoda kufunga kuti iyo polyimide firimu inogadzirwa sei. Pazasi, vagadziri vehunyanzvi vakaita sumo yakadzama, ngatitarisei zvakadzama pamwe chete.

Nzira yekugadzirira firimu ndeyotevera: kanda mhinduro ye polyamic acid mufirimu, tambanudza uye uitevedzere pakupisa kwepamusoro. Iyo firimu ndeyero uye yakajeka, ine hukama hwehukama hwe1.39 ~ 1.45. Iine yakanakisa kupisa tembiricha kuramba, radiation resistance, chemical corrosion resistance uye magetsi ekuisa zvivakwa, uye inogona kushandiswa kwenguva yakareba mumhepo pa250 ~ 280 ℃. Magirazi ekuchinja tembiricha ari pamusoro pe280°C (Upilex R), 385°C (Kapton) uye 500°C (Upilex S). Simba rekusimba ndeye 200 MPa pa20 ° C uye pamusoro pe100 MPa pa200 ° C. Iyo inonyanya kukodzera kushandiswa se substrates uye insulating zvinhu zve flexible akadhindwa edunhu mabhodhi emhando dzakasiyana dzepamusoro-tembiricha dzinodzivirira mota uye midziyo yemagetsi.
