Ke maemo afe a ts’ebeliso ea epoxy glass fiber board
Epoxy glass fiber board e boetse e le epoxy phenolic laminated glass cloth board. Epoxy resin hangata e bolela metsoako ea organic polymer e nang le lihlopha tse peli kapa ho feta tsa epoxy ka har’a molek’hule. Ntle le tse seng kae, boima ba tsona ba limolek’hule bo fapane kaofela. hodimo. Sebopeho sa molek’hule sa epoxy resin se khetholloa ke sehlopha se sebetsang sa epoxy ka har’a ketane ea molek’hule. Sehlopha sa epoxy se ka fumaneha qetellong, bohareng kapa ka sebopeho sa cyclic sa ketane ea molek’hule. Hobane sebopeho sa limolek’hule se na le lihlopha tse sebetsang tsa epoxy, li ka kopana le li-cross-linking reactions le mefuta e fapaneng ea pheko ho etsa li-polymers tse sa tsitsang le tse sa tsitsang tse nang le sebopeho sa marang-rang a litsela tse tharo. The epoxy glass fiber board ea sehlahisoa sena e entsoe ka ho futhumatsa le ho hatella ka epoxy resin. E na le ts’ebetso e phahameng ea mochine mocheso o bohareng le ts’ebetso e tsitsitseng ea motlakase tlas’a mongobo o phahameng. E loketse likarolo tsa sebopeho se phahameng sa insulation bakeng sa mechini, lisebelisoa tsa motlakase le lisebelisoa tsa elektroniki, tse nang le thepa e phahameng ea mochini le dielectric, ho hanyetsa mocheso o motle le ho hanyetsa mongobo, le sehlopha sa ho hanyetsa mocheso F (155 degrees).
Ho na le mefuta e mengata ea epoxy glass fiber board, tse tloaelehileng ke 3240, G11, G10, FR-4, joalo-joalo Li na le ts’ebetso e ts’oanang ea kakaretso, kaofela ke lisebelisoa tse phahameng tsa mocheso, ‘me lintlha li fapane hanyenyane. Ka mohlala, mocheso oa tšebeliso ea FR-4 ke Ho pota 130 ° C, ha mocheso oa tšebeliso ea G11 o ka fihla ho 180 ° C. Joale tšebetso e joang? Sehloohong sena, ke tla bua ka maemo a tšebeliso ea epoxy glass fiber board.
1. Mocheso o sebetsang oa epoxy glass fiber board ke likhato tse 120 tsa Celsius. E ka sebelisoa tikolohong ea likhato tse 130 tsa Celsius ka nako e khuts’oane. Haeba e feta mocheso ona, e tla sotheha, e pepesehe ‘me e se ke ea sebelisoa.
2. E na le lisebelisoa tse ntle tsa motlakase, tse nang le matla a dielectric a 1000V / MIL le matla a ho senya a 65 kV, a ka sebetsang ka ho tsoelang pele sebakeng se phahameng le tikoloho ea hona joale.
3. E na le matla a machina, bokhoni bo botle ba mochine, matla a ho hatella a 303 MPa, matla a ho tsitsa a 269 MPa, matla a ho khumama a 455 MPa, le matla a ho kuta a 130 MPa. E khona ho mamella litlamorao tse matla tse tsoang lefats’eng la kantle mme e na le boima bo botle.
4. Lintho tsa lik’hemik’hale li boetse li ntle, ka tekanyo e itseng ea ho hanyetsa ho bola.
5. Ha e chese lelakabe, ha e na bromine, ho latela litekanyetso tsa EU, ha e na tikoloho, ‘me e ke ke ea silafatsa tikoloho. E sebelisoa haholo kantle ho naha.
Ho ka bonoa ho tsoa ka holimo hore ts’ebetso ea epoxy glass fiber board e ntle haholo. E entsoe ka letlapa la fiber la khalase le lohiloeng ka likhoele tse tsoelang pele tse kopantsoeng le resin ea epoxy. E ka etsoa ka ho toba ho latela litlhoko tsa bareki. Haeba likarolo tse sebetsitsoeng li sebetsoa, ka kopo sheba litšoantšo tsa Ts’ebetso.
