Ziziphi iimeko zokusebenzisa i-epoxy glass fiber board

Ibhodi yefayibha yeglasi ye-epoxy ikwayibhodi yelaphu leglasi ye-epoxy phenolic elaminethiweyo. I-epoxy resin ngokubanzi ibhekisa kwiikhompawundi zepolymer eziphilayo eziqulethe amaqela amabini okanye ngaphezulu epoxy kwimolekyuli. Ngaphandle kwabambalwa, iimolekyuli zabo ezizalanayo zahlukile. phezulu. Isakhiwo se-molecular ye-epoxy resin ibonakaliswe liqela elisebenzayo le-epoxy kwi-chain chain. Iqela le-epoxy linokuthi libekwe ekupheleni, phakathi okanye kwi-cyclic structure ye-molecular chain. Ngenxa yokuba i-molecular structure iqulethe amaqela e-epoxy asebenzayo, banokungena kwi-cross-linking reactions kunye neentlobo ezahlukeneyo zee-agents zokunyanga ukwenza iipolymers ezinganyibilikiyo kunye ne-infusible kunye nesakhiwo senethiwekhi yeendlela ezintathu. Ibhodi yefiber yeglasi ye-epoxy yale mveliso yenziwe ngokufudumeza kunye nokucinezela nge-epoxy resin. Inomsebenzi ophezulu womatshini kwiqondo lokushisa eliphakathi kunye nokusebenza kombane okuzinzileyo phantsi komswakama ophezulu. Ifanelekile kwiindawo eziphakamileyo ze-insulation zezakhiwo zoomatshini, izixhobo zombane kunye ne-electronics, ezinezixhobo eziphezulu zoomatshini kunye ne-dielectric, ukumelana nobushushu obuhle kunye nokumelana nokufuma, kunye neklasi yokumelana nobushushu F (155 degrees).

Kukho iintlobo ezininzi ze-epoxy glass fiber board, eziqhelekileyo ziyi-3240, i-G11, i-G10, i-FR-4, njl. Zinentsebenzo eqhelekileyo efanayo, zonke zizinto zokushisa eziphezulu zokushisa, kunye neenkcukacha zihluke kancinci. Umzekelo, ubushushu bokusetyenziswa kwe-FR-4 bujikeleze i-130 ° C, ngelixa ubushushu bokusetyenziswa kwe-G11 bunokufikelela kwi-180 ° C. Ke injani intsebenzo? Kweli nqaku, ndiza kuthetha malunga neemeko zokusetyenziswa kwebhodi ye-epoxy glass fiber.

1. Ubushushu obusebenzayo bebhodi ye-epoxy glass fiber yi-120 degrees Celsius. Ingasetyenziswa kwindawo ye-130 degrees Celsius ngexesha elifutshane. Ukuba idlula eli qondo lobushushu, liya kujika, liqhekeke kwaye lingasebenziseki.

2. Ineempawu ezintle zombane, kunye namandla e-dielectric ye-1000V / MIL kunye ne-voltage breakdown ye-65 kV, enokusebenza ngokuqhubekayo kwi-voltage ephezulu kunye nendawo yangoku.

3. Inokusebenza okunamandla, amandla omatshini alungileyo, amandla acinezelayo angama-303 MPa, amandla okuqina angama-269 MPa, amandla okugoba angama-455 MPa, kunye namandla okucheba angama-130 MPa. Inokumelana neempembelelo ezinamandla ezivela kwihlabathi langaphandle kwaye inokuqina okuhle.

4. Iimpawu zeekhemikhali nazo zilungile, kunye neqondo elithile lokumelana nokubola.

5. I-non-flame retardant, i-non-bromine, ngokuhambelana nemigangatho ye-EU, ihambelana nokusingqongileyo, kwaye ayiyi kungcolisa indalo. Isetyenziswa kakhulu kumazwe angaphandle.

Inokubonwa koku ngasentla ukuba ukusebenza kwebhodi yefiber yeglasi epoxy kuhle kakhulu. Yenziwe ngephepha leglasi lefibre elukiweyo kunye nemicu eqhubekayo edityaniswe ne-epoxy resin. Ingenziwa ngokwezifiso ngokuthe ngqo ngokweemfuno zabathengi. Ukuba iinxalenye ezicutshungulweyo zicutshungulwa, nceda ubhekisele kwimizobo Ukusetyenzwa.
