Dielectric (insulator) yog ib qho ntawm cov nqi zoo thiab tsis zoo nyob rau hauv qhov kev txiav txim ntawm qhov hluav taws xob teb rau lub ntsiab polarization ntawm ib chav kawm ntawm cov ntaub ntawv.Lub dielectric band qhov sib txawv E yog loj (ntau tshaj 4eV), cov electrons nyob rau hauv lub valence band yog ib qho nyuaj rau kev hloov mus rau lub conduction band, tus nqi yog nyob rau hauv ib tug khi lub xeev, yog li ntawd nws yuav tsuas polarized nyob rau hauv hluav taws xob teb, nyuaj rau kev koom tes. hauv kev coj ua.

Lub hom phiaj ntawm kev sib cais conductors ntawm qhov sib txawv muaj peev xwm thiab txwv tsis pub cov khoom siv hluav taws xob tam sim no tuaj yeem ua tiav los ntawm kev siv hluav taws xob rwb thaiv tsev ntawm dielectric.Yog li ntawd, cov ntaub ntawv rwb thaiv tsev muaj cov yam ntxwv ntawm lub zog tawg siab thiab ntim cov khoom tiv thaiv thiab tsis tshua muaj tanδ.Nyob rau hauv daim ntawv thov, nws yog feem ntau yuav tsum tau mus ua si lub luag hauj lwm ntawm mechanical kev them nyiaj yug thiab fixation, tshav kub dissipation thiab txias, arc extinguishing thiab hais txog.Thaum dielectric siv los ua cov khoom siv hluav taws xob, nws tsis txwv rau cov hluav taws xob rwb thaiv tsev, tab sis siv nws cov yam ntxwv ntau yam.Nrog rau txoj kev loj hlob ntawm cov cuab yeej siv siab, kev ua haujlwm dielectric tsim tau sai thiab siv ntau thiab ntau dua.

Nws yuav tsum raug sau tseg tias cov khoom siv hluav taws xob ntawm cov ntaub ntawv insulating muaj feem cuam tshuam nrog ib puag ncig, thiab feem ntau tsis tuaj yeem siv los sawv cev rau kev ua haujlwm ntawm tag nrho cov kev ua haujlwm nrog cov kev ua tau zoo ntsuas nyob rau hauv ib lub voj voog.Tsis tas li ntawd, cov kev sim muaj kev cuam tshuam rau qhov ntsuas qhov tseem ceeb ntawm cov khoom siv.

Jiujiang Xinxing rwb thaiv tsev khoom Co., Ltdtsim thiab tsim ntau yam epoxy iav ntaub laminates, dav siv hauv hluav taws xob, hluav taws xobkev lag luam raws li rwb thaiv tsev qhov chaw, thiab lwm yam., nrog cov khoom zoo thiab cov khoom siv hluav taws xob.Cov khoom siv dav siv hauv hluav taws xob, hluav taws xob, khoom siv hluav taws xob kev lag luam PCB pwm, fixture, generators, switchgear, rectifier thiab lwm yam kev lag luam,lub tuam txhab tsim cov kev ua tau zoo, siab kub resistant, siab dielectric cov ntaub ntawvyog dav siv nyob rau hauv 5 g kev sib txuas lus, lub zog tshiab tsheb, tsheb thauj mus los, loj transformer substation, loj generating set, nuclear fais fab nroj tsuag, cua fais fab generators, thiab lwm yam teb, nws tus kheej-tsim multifunctional composite cov ntaub ntawv nyob rau hauv kev tiv thaiv kev lag luam, aviation thiab aerospace kev lag luam, kev pab cuam kev puas tsuaj thiab lwm yam kev lag luam.
