Polyimide daim kab xev yog dab tsi? Hom nplaum no yog siv los khi ntau yam ntaub ntawv. Qhov tseeb, Kapton, ib zaj duab xis polyimide, yog siv los ua cov pam vov thiab hloov pauv hloov pauv. Nws kuj yog siv nyob rau hauv ntau yam cuab yeej cuab tam thiab spacecraft. Kapton ruaj khov nyob rau hauv ntau qhov kub thiab txias.
Kapton(r) polyimide daim kab xev nta tshwj xeeb hluav taws xob thiab thermal rwb thaiv tsev. Nws nyias, conformable zaj duab xis muaj qhov tshwj xeeb tsim kua muag thiab cuam tshuam tsis kam. High-temperature nplaum nplaum tso cai rau nws tiv taus ntau qhov kub thiab txias. Cov khoom no ua rau nws muaj ntau yam hluav taws xob thiab thermal insulator. Polyimide tapes yog kev lag luam, ua rau lawv xaiv rau ntau daim ntawv thov. Cov npe hauv qab no yog qee qhov txiaj ntsig ntawm Polyimide daim kab xev.
Polyimide daim kab xev muaj ob hom nplaum: silicone thiab acrylic. Silicone adhesive muaj qhov ntsuas kub siab dua, tab sis tsis tuaj yeem siv rau ntawm cov xim pleev xim lossis cov hlau nplaum. Polyimide daim kab xev nrog PSA muaj ob lub xyoo txee lub neej nyob rau hauv ib tug 75-degree ib puag ncig ntawm 50 feem pua ntawm cov av noo. Polyimide tapes nrog silicone nplaum kuj haum rau hluav taws xob rwb thaiv tsev thiab kub-kub hmoov txheej npog npog.
Kapton yog cov khoom siv thermoplastic polyimide uas haum rau kev siv hluav taws xob thiab hluav taws xob sib dhos. Nws yog punctured heev thiab txiav-resistant thiab ua raws li UL510 nplaim retardance qauv. Cov kab xev no muaj nyob rau hauv qhov dav txog li 20 ntiv tes thiab ntim nrog PET liner. High-temperature silicone adhesives pab tuav daim kab xev kom ruaj khov thiab sawb kom huv si. Nws tuaj yeem siv rau hluav taws xob rwb thaiv tsev thiab splicing insulating txheej ntawm cov khoom siv hluav taws xob thiab hluav taws xob.
Polyimide daim kab xevyog ib daim kab xev nplaum zoo heev rau cov ntawv thov kub. Nws cov nplaum silicone yog 1.4 millimeters tuab thiab muab cov thermal thiab tshuaj tiv thaiv zoo heev. Nws tuaj yeem txiav tau yooj yim kom haum rau ib qhov project tshwj xeeb thiab tsis tawm ntawm cov nplaum nplaum tom qab. Ntxiv mus, nws nyias thiab hloov tau rov qab ua rau nws yooj yim rau tshem tawm thiab siv daim kab xev sai sai thiab huv si, tso cai rau me ntsis mess.
Kapton daim kab xev yog lwm qhov piv txwv ntawm Polyimide daim kab xev. Kapton(r) HN yog ntau yam yeeb yaj kiab uas muaj qhov sib npaug zoo ntawm cov khoom nyob rau ntau qhov kub thiab txias. Nws yog ib qho kev xaiv zoo rau ntau daim ntawv thov thiab feem ntau yog siv rau kev tsim khoom siv hluav taws xob. Kapton polyimide daim kab xev kuj muaj nyob rau hauv cov xim ntshiab.
Kapton daim kab xev yog dav siv nyob rau hauv daim ntawv thov hluav taws xob thiab kuj yog feem ntau siv raws li ib tug kub daim npog qhov ncauj nyob rau hauv hmoov txheej txheej txheem. Polyimide daim kab xev kuj yog siv los ua hlau rwb thaiv tsev ntawm lub dav hlau. Nws muaj zoo heev mechanical zog thiab dielectric zog. Vim li no, nws yog feem ntau siv hauv electronics thiab satellites. Nws qhov kub-kub kuj ua rau nws zoo tagnrho rau ntau yam kev siv. Ntxiv rau qhov no, Kapton daim kab xev tuaj yeem ua thiab laminated.
Ntxiv rau nws qhov kub thiab txias thiab tshuaj tiv thaiv, Kapton daim kab xev yog nyias thiab ua tau raws, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau npog cov khoom muag muag lossis cov khoom rhiab. Tsis tas li ntawd, nws tseem muaj qhov ruaj khov thiab yuav tsis yaj, txawm tias raug tshav kub. Ntxiv rau cov txiaj ntsig no, Polyimide daim kab xev kuj tau siv dav hauv kev lag luam thiab kev tsim khoom. Cov ntaub ntawv nws muaj yog sib xws nrog ntau yam substrates, ua kom muaj txiaj ntsig zoo thiab ua haujlwm zoo.
