Aluminium Ntawv Nyiaj Mylar Daim kab xev:
Aluminium ntawv nyiaj Mylar daim kab xevyog tsim los ntawm mos aluminium ntawv ci thiab polyester zaj duab xis, uas yog ua ke siv gravure txheej. Tom qab kho, aluminium ntawv nyiaj Mylar yog txiav rau hauv yob. Nws tuaj yeem raug kho nrog cov nplaum, thiab tom qab txiav tuag, nws yog siv rau kev thaiv thiab kev sib dhos hauv av. Aluminium ntawv nyiaj Mylar feem ntau yog siv rau hauv kev sib txuas lus cables rau kev cuam tshuam kev tiv thaiv. Cov ntawv txhuas txhuas Mylar muaj xws li ib leeg-sab txhuas ntawv ci, ob-sided aluminium ntawv ci, npauj npaim aluminium ntawv ci, kub-kua aluminium ntawv ci, aluminium ntawv ci daim kab xev, thiab txhuas-yas daim kab xev. Aluminium txheej muab kev ua haujlwm zoo heev, tiv thaiv kev ua haujlwm, thiab tiv thaiv corrosion, ua rau nws tsim nyog rau ntau yam kev siv. Lub shielding ntau feem ntau spans ntawm 100KHz mus rau 3GHz.
Ntawm cov no, kub-melt aluminium ntawv nyiaj Mylar yog coated nrog ib txheej ntawm kub-kua nplaum nplaum ntawm sab uas hu rau cable. Nyob rau hauv high kub preheating, kub-melt nplaum bonds nruj nreem kaw nrog lub cable core rwb thaiv tsev, txhim kho lub cable tiv thaiv kev ua tau zoo. Nyob rau hauv sib piv, txheem txhuas ntawv ci tsis muaj cov nplaum nplaum thiab tsuas yog qhwv ib ncig ntawm lub rwb thaiv tsev, ua rau qis shielding efficiency.
Nta thiab Daim Ntawv Thov:
Aluminium ntawv nyiaj Mylar feem ntau yog siv los tiv thaiv cov hluav taws xob hluav taws xob ntau zaus thiab tiv thaiv lawv los ntawm kev sib cuag nrog cable tus neeg xyuas pib, uas tuaj yeem cuam tshuam tam sim no thiab nce crosstalk. Thaum high-frequency electromagnetic nthwv dej ntsib txhuas ntawv ci, raws li Faraday txoj cai electromagnetic induction, cov nthwv dej ua raws li cov ntawv ci thiab induce tam sim no. Lub sijhawm no, tus neeg xyuas pib yuav tsum tau coj cov induced tam sim no rau hauv av, tiv thaiv kev cuam tshuam nrog cov teeb liab kis. Cables nrog aluminium foil shielding feem ntau xav tau qhov tsawg kawg nkaus ntawm 25% rau cov ntawv txhuas txhuas.
Daim ntawv thov feem ntau yog nyob rau hauv kev sib txuas xov tooj, tshwj xeeb tshaj yog nyob rau hauv tsev kho mob, cov chaw tsim khoom, thiab lwm qhov chaw uas muaj hluav taws xob hluav taws xob tseem ceeb lossis ntau lub zog siv hluav taws xob. Tsis tas li ntawd, lawv tau siv hauv tsoomfwv cov chaw thiab lwm qhov chaw uas muaj kev ruaj ntseg network siab.
Copper/Aluminium-Magnesium Alloy Hlau Braiding (Hloov Shielding):
Hlau shielding yog tsim los ntawm braiding hlau xaim rau hauv ib qho qauv siv lub tshuab braiding. Cov ntaub thaiv npog feem ntau suav nrog tooj liab hlau (tinned tooj liab hlau), txhuas hlau hlau, tooj liab-clad txhuas,daim kab xev(copper-yas daim kab xev), aluminium daim kab xev (aluminium-yas daim kab xev), thiab steel daim kab xev. Cov qauv braiding sib txawv muab ntau qib ntawm kev tiv thaiv kev ua haujlwm. Kev tiv thaiv kev ua haujlwm ntawm cov txheej braiding yog nyob ntawm cov yam ntxwv xws li hluav taws xob conductivity thiab sib nqus permeability ntawm cov hlau, nrog rau cov txheej txheem, kev pab them nqi, thiab lub kaum sab xis braiding.
Qhov ntau cov khaubncaws sab nraud povtseg thiab ntau dua qhov kev tiv thaiv, qhov zoo ntawm kev tiv thaiv kev ua haujlwm. Lub kaum sab xis braiding yuav tsum tau tswj ntawm 30 ° -45 °, thiab rau ib txheej braiding, qhov kev pab yuav tsum yog tsawg kawg yog 80%. Qhov no tso cai rau lub shielding kom nqus electromagnetic nthwv dej los ntawm cov txheej txheem xws li sib nqus hysteresis, dielectric poob, thiab tsis kam tiv thaiv, hloov lub zog tsis xav tau mus rau hauv tshav kub lossis lwm yam ntaub ntawv, tiv thaiv cov cable los ntawm electromagnetic cuam tshuam.
Nta thiab Daim Ntawv Thov:
Braided shielding feem ntau yog tsim los ntawm tinned tooj liab hlau los yog txhuas-magnesium alloy hlau thiab feem ntau yog siv los tiv thaiv kev cuam tshuam tsawg zaus electromagnetic. Lub hauv paus ntsiab lus ntawm kev ua haujlwm zoo ib yam li cov ntawv txhuas txhuas. Rau cables siv braided shielding, lub mesh ntom yuav tsum tau ntau tshaj 80%. Hom braided shielding no yog dav siv los txo cov crosstalk sab nraud nyob rau hauv ib puag ncig uas muaj ntau cov cables muab tso rau hauv tib lub cable tais. Tsis tas li ntawd, nws tuaj yeem siv rau kev tiv thaiv ntawm cov khub hlau, ua rau qhov sib tw ntev ntawm cov hlua hlau thiab txo cov kev sib tw twisting rau cov cables.
