Aluminium foil Mylar: Cov ntawv txhuas txhuas Mylar siv cov ntawv txhuas mos thiab polyester zaj duab xis ua cov ntaub ntawv raw, thiab yog sib xyaw los ntawm gravure txheej. Tom qab aluminium ntawv nyiaj Mylar yog matured, nws yog txiav thiab dov. Yuav nruab nrog cov kua nplaum, aluminium ntawv nyiaj Mylar tuag-txiav tuaj yeem siv los sib sau ua ke tiv thaiv thiab hauv av. Aluminium ntawv nyiaj Mylar daim kab xev yog tsuas yog siv nyob rau hauv lub scramble screen ntawm kev sib txuas lus cables. Aluminium ntawv nyiaj Mylar muaj xws li: ib leeg-sab txhuas ntawv ci, ob-sided aluminium ntawv ci, finned aluminium ntawv ci, kub-melt aluminium ntawv ci, aluminium ntawv ci daim kab xev, aluminium-yas composite daim kab xev; txhuas txheej muab kev ua tau zoo heev, kev tiv thaiv kev ua haujlwm thiab kev tiv thaiv corrosion tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm ntau yam sib txawv. Kev tiv thaiv ntau yam yog 100K-3GHz, thiab kub-melt aluminium ntawv nyiaj Mylar yog coated nrog ib txheej ntawm kub-melt nplaum nplaum nyob rau sab qhov twg cov ntawv ci txhuas thiab cov cable sib cuag. Nyob rau hauv cov ntaub ntawv ntawm kub preheating, kub yaj nplaum nplaum yuav nruj nreem qhwv nrog lub cable core rwb thaiv tsev, uas yuav pab tau rau lub shielding kev ua tau zoo ntawm lub cable, thaum lub zoo tib yam aluminium ntawv ci tsis nplaum, thiab nws tsuas yog qhwv ntawm lub cable. core rwb thaiv tsev. Kev tiv thaiv kev ua haujlwm tsis zoo.
Nta thiab daim ntawv thov thaj chaw:
Aluminium ntawv nyiaj Mylar feem ntau yog siv los tiv thaiv cov hluav taws xob hluav taws xob ntau zaus, tiv thaiv cov hluav taws xob hluav taws xob tsis zoo los ntawm kev tiv tauj tus neeg xyuas pib ntawm cable thiab tsim cov hluav taws xob induced, nce crosstalk. Thaum high-frequency electromagnetic nthwv dej kov cov txhuas ntawv ci, raws li Faraday' txoj cai ntawm electromagnetic induction, electromagnetic nthwv dej yuav ua raws li qhov chaw ntawm aluminium ntawv ci thiab induce tam sim no. Lub sijhawm no, tus neeg xyuas pib yuav tsum tau coj cov induced tam sim no mus rau hauv av kom tsis txhob muaj qhov cuam tshuam tam sim no los ntawm kev cuam tshuam rau lub teeb liab kis. Cov hlau uas siv cov ntawv txhuas txhuas ua ib txheej thaiv feem ntau xav tau tias qhov rov ua dua ntawm cov ntawv txhuas tsis tuaj yeem tsawg dua 25%. Cov ntawv thov ntau tshaj plaws yog tam sim no nyob rau hauv kev sib txuas network. Hom kab hluav taws xob network no feem ntau yog siv hauv tsev kho mob, cov chaw tsim khoom thiab lwm qhov chaw uas muaj hluav taws xob hluav taws xob muaj zog lossis muaj cov khoom siv hluav taws xob ntau; Tsis tas li ntawd, nws kuj tseem siv rau hauv thaj chaw uas muaj kev ruaj ntseg network siab xws li tsoomfwv.
Braided mesh xws li tooj liab / txhuas-magnesium-kub hlau (hlau thaiv): hlau thaiv yog tsim los ntawm braiding hlau nyob ntawm tej yam braided qauv los ntawm cov khoom siv braiding. Cov ntaub thaiv npog feem ntau yog tooj liab hlau (tinned tooj liab hlau), aluminium alloy hlau, tooj liab-clad aluminium, tooj liab daim kab xev (tooj liab-yas daim kab xev), txhuas daim kab xev (aluminium-yas daim kab xev), steel daim kab xev thiab lwm yam ntaub ntawv, sib xws rau hlau braiding. , cov txheej txheem sib txawv muaj qhov sib txawv tiv thaiv kev ua tau zoo, kev tiv thaiv kev ua tau zoo ntawm cov hlua khi tsis yog tib yam li cov hlau nws tus kheej Cov hluav taws xob conductivity thiab sib nqus permeability muaj feem xyuam rau lwm yam kev ua haujlwm. Cov khaubncaws sab nraud povtseg ntau dua, qhov ntau dua qhov kev pab cuam, qhov me dua lub braid lub kaum sab xis, thiab qhov zoo dua qhov kev tiv thaiv ntawm braid. Lub kaum sab xis braid yuav tsum tau tswj ntawm 30-45 °. Txheej txheej, qhov kev pab them nqi yog nyiam tshaj 80%, yog li nws tuaj yeem hloov mus rau hauv lub zog hluav taws xob, lub zog muaj peev xwm thiab lwm yam ntawm lub zog los ntawm cov txheej txheem xws li hysteresis poob, dielectric poob, tsis kam tiv thaiv, thiab lwm yam., siv lub zog tsis tsim nyog, thiab ua tiav shielding thiab nqus ntawm electromagnetic tsis.
Nta thiab daim ntawv thov thaj chaw:
Woven nets feem ntau yog woven los ntawm tinned round tooj liab xov hlau los yog txhuas-magnesium-kub xov hlau, feem ntau yog los tiv thaiv tsis tshua muaj zaus electromagnetic yoj cuam tshuam, thiab lawv txoj kev ua hauj lwm yog tib yam li txhuas ntawv ci. Shielded cables siv braided nets feem ntau yuav tsum muaj tsawg kawg yog 80% qhov ceev ntawm cov nets braided. Hom braided nets no feem ntau yog siv los nteg ntau cov cables nyob rau hauv tib lub qhov, uas tuaj yeem txo cov crosstalk sab nraud ntawm ntau cov cables. Tsis tas li ntawd, nws kuj tseem siv tau rau kev tiv thaiv ntawm cov khub los ua kom qhov sib tw ntev ntawm cov khub thiab txo qhov kev sib tw sib tw rau cov kab.
