Makhe sijonge kwiipropati zefilimu ye-polyimide
Indlela yokulungiselela ifilimu yile: isisombululo se-polyamic acid sifakwe kwifilimu, soluliwe, size sifaniswe kwiqondo lokushisa eliphezulu. Ifilimu iphuzi kwaye iyabonakala, kunye nokuxinana kwe-1.39 ~ 1.45. Inoxhathiso olubalaseleyo lobushushu obuphezulu, ukuxhathisa kwimitha, ukuxhathisa ukubola kweekhemikhali kunye neempawu zokugquma umbane. Ingasetyenziselwa ixesha elide emoyeni kwi-250 ~ 280 ℃. Amaqondo obushushu okutshintsha kweglasi ngokulandelanayo 280 ° C (Upilex R), 385 ° C (Kapton) nangaphezulu kwe500 ° C (Upilex S). Amandla e-tensile yi-200 MPa kwi-20 ° C kwaye inkulu kune-100 MPa kwi-200 ° C. Ikulungele ngokukhethekileyo ukusetyenziswa njenge-flexible eprintiweyo yebhodi yesekethe substrate kunye neentlobo ezahlukeneyo zobushushu obuphezulu obuxhathisa umbane kunye nezixhobo zokugquma umbane.
Okokuqala, makhe sijonge kwiimpawu ezibonakalayo zefilimu ye-polyimide
I-Thermosetting polyimide inozinzo oluhle kakhulu lwe-thermal, ukuxhathisa iikhemikhali kunye neempawu zoomatshini, kwaye ihlala i-orenji. Amandla e-flexural e-graphite okanye i-glass fiber eqiniswe i-polyimide inokufikelela kwi-345 MPa, kwaye i-modulus eguquguqukayo inokufikelela kwi-20 GPa. I-Thermoset polyimide ine-creep encinci kakhulu kwaye inamandla aphezulu. Uluhlu lobushushu bokusetyenziswa kwe-polyimide lugubungela uluhlu olubanzi, ukusuka ku-minus ikhulu le-degrees ukuya kwi-Baidu ezimbini okanye ezintathu.
Makhe sijonge kwiimpawu zeekhemikhali zefilimu ye-polyimide.
I-Polyimide izinzile ngokwekhemikhali. I-Polyimide ayifuni ukongeza i-flame retardant ukuthintela ukutsha. Iipolyimides ngokubanzi ziyakwazi ukumelana nezinyibilikisi zekhemikhali ezifana neehydrocarbons, esters, ethers, alcohols kunye nechlorofluorocarbons. Zikwaxhathisa kwiiasidi ezibuthathaka kodwa azikhuthazwa ukuba zisetyenziswe kwiindawo eziqinileyo zealkali kunye ne-inorganic acid. Iipolyimides ezithile ezifana ne-CP1 kunye ne-CORIN XLS ziyanyibilika kwizinyibilikisi. Le propati inceda ukuphuhlisa izicelo zabo kwi-spray coating kunye nokushisa okuphantsi kwe-crosslinking.
