3250 Epoxy Glassfiber Laminated Sheet
Tlhaloso ea Sehlahisoa
Sehlahisoa sena ke sehlahisoa sa laminated se entsoeng ka lesela la khalase le sa sebetseng la alkali, ka ho tobetsa ka mocheso o phahameng oa Tg epoxy resin joalo ka binder. mongobo.Thermostability ke grade F, e loketse mefuta eohle ea motlakase, lisebelisoa tsa motlakase, tsa elektroniki le tse ling.
Likaroloana
1.Botsitso bo botle ba motlakase tlas'a mongobo o phahameng;
2.Matla a phahameng a mochini tlas'a mocheso o phahameng,
sekhahla sa ho boloka matla a mochini ≥50% tlasa 180 ℃;
3.Ho hanyetsa mongobo;
4.Ho hanyetsa mocheso;
5.Ho hanyetsa mocheso: Kereiti ea H
Index ea Ts'ebetso e ka Sehloohong
Ho ea ka GB/T 1303.4-2009 thermosetting resin industrial hard laminates - Karolo ea 4: epoxy resin hard laminates.
Ponahalo: bokaholimo bo lokela ho ba bo bataletseng, bo se na li-bubble, likoting le masoba, empa liphoso tse ling tse sa amang ts'ebeliso li lumelletsoe, joalo ka: mengoapo, indentation, matheba le matheba a seng makae. sefahleho sa ho qetela se ke ke sa senyeha le ho phunyeha.
Kopo
E loketse mefuta eohle ea enjene, lisebelisoa tsa motlakase, tsa elektroniki le tse ling.
