Dab tsi yog qhov kev siv ntawm epoxy iav fiber board

Epoxy iav fiber board kuj tseem yog epoxy phenolic laminated iav ntaub board. Epoxy resin feem ntau yog hais txog cov organic polymer tebchaw uas muaj ob lossis ntau pawg epoxy hauv cov molecule. Tsuas yog qee qhov, lawv cov txheeb ze molecular pawg sib txawv. siab. Cov qauv molecular ntawm epoxy resin yog tus cwj pwm los ntawm pawg epoxy nquag hauv cov saw hlau molecular. Cov pab pawg epoxy tuaj yeem nyob ntawm qhov kawg, hauv nruab nrab lossis hauv cov qauv cyclic ntawm cov saw hlau molecular. Vim hais tias cov qauv molecular muaj active epoxy pawg, lawv muaj peev xwm mus hla kev sib txuas cov tshuaj tiv thaiv nrog ntau hom curing agents los tsim insoluble thiab infusible polymers nrog peb-txoj kev network qauv. Lub epoxy iav fiber ntau lub rooj tsavxwm ntawm cov khoom no yog tsim los ntawm cua sov thiab nias nrog epoxy resin. Nws muaj kev ua tau zoo txhua yam ntawm qhov nruab nrab kub thiab ruaj khov hluav taws xob ua haujlwm nyob rau hauv cov av noo siab. Nws yog qhov tsim nyog rau cov khoom siv hluav taws xob zoo rau cov tshuab, cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, nrog cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, cov cua sov zoo thiab cov dej tsis zoo, thiab cov cua sov ua haujlwm F (155 degrees).

Muaj ntau ntau hom epoxy iav fiber ntau lub rooj tsavxwm, cov khoom siv yog 3240, G11, G10, FR-4, thiab lwm yam. Lawv muaj cov kev ua tau zoo tib yam, yog tag nrho cov khoom siv rwb thaiv tsev kub, thiab cov ntsiab lus sib txawv me ntsis. Piv txwv li, kev siv kub ntawm FR-4 yog nyob ib ncig ntawm 130 ° C, thaum siv kub ntawm G11 tuaj yeem ncav cuag 180 ° C. Yog li cas qhov kev ua tau zoo? Hauv tsab xov xwm no, kuv yuav tham txog kev siv cov txheej txheem ntawm epoxy iav fiber board.

1. Kev khiav hauj lwm kub ntawm epoxy iav fiber board yog 120 degrees Celsius. Nws tuaj yeem siv rau hauv ib puag ncig ntawm 130 degrees Celsius hauv lub sijhawm luv luv. Yog hais tias nws tshaj qhov kub no, nws yuav warp, tawg thiab yuav siv tsis tau.

2. Nws muaj cov khoom siv hluav taws xob zoo, nrog lub zog dielectric ntawm 1000V / MIL thiab qhov hluav taws xob tawg ntawm 65 kV, uas tuaj yeem ua haujlwm tsis tu ncua nyob rau hauv ib puag ncig high voltage thiab tam sim no.

3. Nws muaj zog machinability, zoo txhua yam muaj peev xwm, compressive zog ntawm 303 MPa, tensile zog ntawm 269 MPa, dabtsi yog khoov zog ntawm 455 MPa, thiab shear zog ntawm 130 MPa. Nws tuaj yeem tiv taus qhov cuam tshuam zoo los ntawm lub ntiaj teb sab nraud thiab muaj qhov zoo toughness.

4. Cov khoom siv tshuaj lom neeg kuj zoo, nrog rau qee qhov kev tiv thaiv corrosion.

5. Nws yog non-flame retardant, non-bromine, raws li EU qauv, ib puag ncig tus phooj ywg, thiab yuav tsis ua phem rau ib puag ncig. Nws yog siv ntau nyob txawv teb chaws.

Nws tuaj yeem pom los ntawm cov saum toj no tias kev ua haujlwm ntawm epoxy iav fiber ntau pawg thawj coj saib zoo heev. Nws yog ua los ntawm iav fiber ntau daim ntawv woven nrog nruam filaments bonded nrog epoxy resin. Nws tuaj yeem raug kho ncaj qha raws li cov neeg siv khoom xav tau.
