yuav ua li cas xaiv epoxy fiberglass board?

Lub epoxy iav fiber ntau pawg thawj coj saib nyob rau hauv kev ua lag luam feem ntau muab faib ua: 3240 epoxy iav fiber board thiab FR4 epoxy iav fiber board.

Thaum peb yuav, yuav muaj qhov sib txawv ntawm halogen-dawb thiab halogen-dawb, yog li dab tsi yog cov ntsiab lus halogen siv hauv epoxy iav fiberboard? Dab tsi yog qhov txawv ntawm halogen dawb thiab halogen dawb? Peb yuav tsum xaiv li cas thaum peb yuav?

Cia peb pib tham txog dab tsi halogen? Nws lub luag haujlwm yog dab tsi?

Cov ntsiab lus halogen hais ntawm no yog hais txog fluorine, chlorine, bromine, iodine, thiab astatine. Lawv tuaj yeem ua rau cov nplaim hluav taws kub hnyiab, tab sis lawv muaj tshuaj lom. Yog tias lawv hlawv, lawv yuav tso cov pa phem xws li dioxins thiab benzofurans. , Nws kuj muaj cov pa luam yeeb hnyav thiab tsw, uas yooj yim ua rau mob qog noj ntshav thiab ua rau muaj kev phom sij loj. Nws kuj ua rau muaj kev phom sij rau ib puag ncig.

Txij li cov ntsiab lus halogen muaj teeb meem, vim li cas coob tus neeg thiaj xaiv cov khoom no? Tau kawg, qhov tseem ceeb tshaj plaws yog tus nqi. Txawm hais tias tsis muaj halogen yog qhov zoo hauv txhua qhov, tus nqi yog me ntsis kim dua. Tab sis tsis muaj qhov sib txawv tseem ceeb ntawm halogen-dawb thiab halogen-dawb.

Vim tias halogen-dawb epoxy iav fiber ntau pawg thawj coj tau ntxiv nrog phosphorus, nitrogen thiab lwm yam ntsiab lus, nws tuaj yeem ua rau cov nplaim hluav taws. Thaum cov phosphorus-muaj resin kub hnyiab, nws yuav decomposed rau hauv metaphosphoric acid los ntawm tshav kub los ua ib tug tiv thaiv zaj duab xis, uas tiv thaiv lub epoxy iav fiber board los ntawm kev sib cuag huab cua. , Yog tsis muaj oxygen txaus, cov xwm txheej rau kev sib txuas tsis tuaj yeem ncav cuag, thiab cov nplaim taws tawm ntawm nws tus kheej. Tab sis halogen-dawb yog ntau tus phooj ywg ib puag ncig thiab muaj txiaj ntsig zoo rau kev txhim kho yav tom ntej ntawm cov ntaub ntawv insulating.

Tsis tas li ntawd, lub halogen-dawb epoxy iav fiber ntau lub rooj tsavxwm muaj ntau yam zoo xws li ya raws tsis kam, kub tsis kam, thiab ruaj khov thermal ua haujlwm. Nws tuaj yeem siv nyob rau hauv qhov chaw ntub dej, txawm tias koj tau kov cov tshuaj tsis raug cai, koj tsis tas yuav txhawj xeeb txog kev corroded. Txawm li cas los xij, vim tus nqi siab ntawm halogen-dawb epoxy iav fiber board, nws raug txwv. Txawm li cas los xij, nrog rau kev txhim kho thev naus laus zis thiab kev txhim kho ntawm cov ntaub ntawv rwb thaiv tsev, peb ntseeg tias lub rooj tsav xwm zoo ib puag ncig no yuav txhawb nqa dav.
