D279 Epoxy Pre-impregnation DMD oo loogu talagalay trasnformers nooca qalalan
D279 waxa laga sameeyay DMD iyo resin u adkaysta kulaylka epoxy ee gaarka ah. Waxay leedahay sifooyinka nolosha kaydinta dheer, heerkulka daawaynta hooseeya iyo wakhtiga daawaynta oo gaaban. Ka dib markii la daaweeyay, waxay leedahay sifooyin koronto oo heer sare ah, dhejis wanaagsan iyo iska caabbinta kulaylka. Cadaadiska kulaylka waa Class F. Waxa kale oo loo yaqaan 'Prepreg DMD', pre-impregnaed DMD, warqad jilicsan oo jilicsan oo isku dhafan oo loogu talagalay transformers qalalan.
Tilmaamaha Alaabta
D279 epoxy pre-impregnated DMD waxay leedahay sifooyin koronto oo aad u wanaagsan, xabag wanaagsan iyo iska caabin kulaylka.
Codsiyada
D279 epoxy pre-impregnated DMD waxa loo isticmaalaa dahaarka lakabka ama dahaarka xadhkaha hoose ee naxaasta/foil aluminium dabaysha ee isbedbedeliyeyaasha nooca engegan iyo sidoo kale dahaarka godka iyo dahaarka liner ee Class B iyo F matoorada korontada iyo qalabka korontada. Waxa kale oo loo yaqaan sida Prepreg DMD, Prepreg insulation warqad isku dhafan oo loogu talagalay transformers nooca qalalan.
Tilmaamaha Sahayda
Ballaca magaca:1000mm.
Miisaanka magaca: 50± 5kg / Roll.
Qaybaha waa in aanay ka badnaan 3 duub.
Midabka: midab cad ama casaan.
Muuqashada
Oogada sare waa inay ahaato mid fidsan, oo xor ka ah xabagta aan sinnayn iyo wasakhda saameeya waxqabadka. Marka la duubo, korkeeda waa inaan la isku dhejin midba midka kale. Ka madhan cilladahaas sida xuubabka, xumbo iyo laalaabyada.
Baakadaha iyo Kaydinta
D279 waa in lagu duuduubaa caag ka dibna lagu ridaa kartoon nadiif ah oo qalalan
Nolosha kaydinta waa 6 bilood heerkul ka hooseeya 25 ℃ ka dib markaad ka baxdo warshadda. Haddii muddada kaydinta ay ka badan tahay 6 bilood, badeecada weli waa la isticmaali karaa marka la tijaabiyo si loogu qalmo. Alaabta waa in la dhigaa oo/ama lagu kaydiyaa si toosan oo laga fogeeyo dabka, kulaylka iyo qorraxda tooska ah.
