Ziziphi iimpawu zefilimu ye-polyimide

Ifilimu yePolyimide yinto esebenzayo kakhulu, kukho iindawo ezininzi apho ingasetyenziselwa khona, kodwa kubathengi kunye nabahlobo abafuna ukuthenga, kufuneka siqale siqonde ukuba zeziphi iipropati zefilimu ye-polyimide. Apha, thina Makhe sijonge kwintshayelelo engezantsi ngokweenkcukacha.

Ifilimu yePolyimide

Ifilimu yePolyimide isetyenziswa kakhulu kwiinjini zokutsala, iimoto ezingaphantsi kwamanzi, izixhobo zamandla enyukliya, iingcingo ezinobushushu obuphezulu kunye neentambo, iingcingo ze-electromagnetic, izixhobo zombane ezikhethekileyo, imibhobho yebhasi, iimaski zerhasi, iinxalenye zesekethe eziprintiweyo ezinobushushu obuphezulu, iisekethe zephaneli ecaba, kunye izakhelo zekhoyili yelizwi lesithethi, njl njl. Yeyona kuphela ifilimu yepolyimide engajikiyo esetyenziselwa ukusika ukufa eTshayina. I-Thermosetting polyimide inozinzo oluhle kakhulu lwe-thermal, ukumelana neekhemikhali kunye neempawu zoomatshini, kwaye zihlala zi-orenji. Amandla e-flexural kunye ne-flexural modulus yegraphite okanye i-glass fiber eqiniswe i-polyimide inokufikelela kwi-345 MPa kunye ne-20 MPa, ngokulandelanayo. I-Thermosetting polyimide ine-creep ephantsi kunye namandla aphezulu okuqina. Uluhlu lobushushu besicelo se-polyimide lubanzi kakhulu, ukusuka ku-minus 100 degrees ukuya kwi-Baidu ezimbini okanye ezintathu. I-Polyimide izinzile ngokwekhemikhali.

I-Polyimide inokungatshi xa ivutha ngaphandle kokubuyiswa komlilo. Iipolyimides eziqhelekileyo zixhathisa kwiikhemikhali zokunyibilikisa, ezifana ne-hydrocarbons, esters, ethers, alcohols kunye ne-chlorofluorocarbons. Kananjalo ziyakwazi ukumelana ne-acids ezibuthathaka, kodwa azikhuthazwa ukuba zisetyenziswe kwiindawo eziqinileyo ze-alkali kunye ne-inorganic acid. Ezinye iipolyimides, ezifana ne-CP1 kunye ne-CORINXLS, zinyibilika kwi-solvents, ezinceda ukuphuhlisa izicelo zabo ngokutshiza okuphantsi kobushushu kunye nokudibanisa.
