EPGC203/G11 Epoxy iav ntaub laminated board
Kev piav qhia txog khoom
Cov khoom no yog ua los ntawm cov ntaub ntawv hluav taws xob uas tsis yog alkali iav fiber ua cov khoom siv thaub qab, nrog cov tshuaj epoxy TG siab ua cov binder los ntawm kev nias kub laminated hauv qab 155 degree kub. Nws muaj lub zog siab hauv qab qhov kub thiab txias, tseem muaj lub zog muaj zog, cov khoom siv hluav taws xob zoo hauv qab qhov chaw qhuav thiab ntub, tuaj yeem siv rau hauv qhov chaw ntub dej thiab roj transformer. Nws yog rau qib F kub tsis kam insulating khoom. Cov ntaub ntawv kev ua haujlwm zoo ib yam li FR5, tab sis tsis yog hluav taws kub retardant.
Kev Ua Raws Li Cov Qauv
Raws li GB/T 1303.4-2009 hluav taws xob thermosetting resin industrial hard laminates - Ntu 4: epoxy resin hard laminates, IEC 60893-3-2-2011 cov ntaub ntawv rwb thaiv tsev - hluav taws xob thermosetting resin industrial hard laminates - Ntu 3-2 ntawm cov khoom siv ib leeg EPGC203.
Cov yam ntxwv
1. Muaj kev ruaj ntseg hluav taws xob siab nyob rau hauv cov av noo siab;
2. Cov khoom siv kho tshuab zoo heev;
3. Muaj zog kho tshuab siab nyob rau hauv qhov kub siab;
4. Ua kom tsis muaj dej noo ntau;
5. Ua kom kub heev;
6. Kev kub tsis kam: Qib F
Daim Ntawv Thov
Siv tau rau txhua yam ntawm lub cev muaj zog, hluav taws xob, hluav taws xob thiab lwm yam teb, siv dav hauv lub cev muaj zog, cov khoom siv hluav taws xob ua cov khoom siv rwb thaiv tsev, cov hloov hluav taws xob siab, cov hloov hluav taws xob siab (xws li cov khoom siv rwb thaiv tsev ntawm lub cev muaj zog stator ntawm ob qho kawg, lub phaj kawg ntawm lub rotor, daim flange ntawm lub rotor, daim wedge ntawm qhov, phaj ntawm cov xov hlau, thiab lwm yam).
