Electromagnetic shielding npuag yog cov khoom siv ua haujlwm los ntawm cov txheej txheem tshwj xeeb (xws li hlau fiber ntau sib xyaw, hlau plating, lossis txheej txheej txheej), feem ntau yog siv los thaiv lossis txo cov hluav taws xob hluav taws xob. Nws cov yam ntxwv tseem ceeb ntawm kev ua haujlwm muaj xws li:
Electromagnetic shielding muaj txiaj ntsig zoo: Qhov no yog qhov taw qhia tseem ceeb, feem ntau qhia hauv decibels (dB). High-Cov ntaub thaiv npog zoo tuaj yeem ua tiav kev tiv thaiv kev ua haujlwm ntawm 30-60dB lossis siab dua hauv 30MHz-3GHz zaus band, sib xws rau cov hluav taws xob thaiv hluav taws xob ntawm 99.9% mus rau 99.999%, tiv thaiv cov hluav taws xob tsis zoo uas tsim los ntawm cov khoom siv hluav taws xob xws li cov xov tooj ntawm tes, microwaves, qhov cub.
Conductivity: Qhov qis ntawm qhov chaw tiv taus, qhov zoo dua cov nyhuv shielding. Feem ntau, qhov kev tiv thaiv tsawg dua 100 milliohms / cm² yuav tsum tau ua kom muaj hluav taws xob zoo li qub lossis cuam tshuam tam sim no, tiv thaiv hluav taws xob theem nrab.
Kev ua pa thiab kev nplij siab: Tsis zoo li cov hlau ntshiab zoo tib yam, cov ntaub thaiv npog yuav tsum xav txog qhov hnav lossis siv cov xwm txheej. Los ntawm kev sib xyaw nrog cov fibers ntuj (xws li paj rwb thiab polyester) los yog siv cov txheej txheem microporous txheej, ua pa zoo thiab noo noo permeability tuaj yeem tswj tau thaum ua kom muaj kev tiv thaiv zoo, ua rau nws tsim nyog rau kev hnav khaub ncaws poj niam, tiv thaiv - cov khaub ncaws hluav taws xob, cov ntaub thaiv npog, thiab lwm yam. Washability thiab Durability: Kev ntxhua khaub ncaws ntau tuaj yeem cuam tshuam cov qauv ntawm cov hlau; yog li ntawd, siab - cov khoom zoo yuav tsum tsis txhob muaj kev tiv thaiv tus nqi qis dua 10%-20% tom qab kaum ob tus qauv ntxuav. Lawv kuj yuav tsum muaj qee yam kev tiv thaiv rau kev puas tsuaj thiab khoov.
Kev tiv thaiv ib puag ncig thiab kev nyab xeeb: Cov khoom yuav tsum tsis muaj cov hlau hnyav heev (xws li txhuas thiab cadmium), tsis muaj ntxhiab tsw ntxhiab, thiab ua rau tsis muaj kev fab tshuaj rau ntawm daim tawv nqaij. Qee cov khoom kuj tseem muaj cov haujlwm ntxiv xws li tshuaj tua kab mob thiab cov nplaim hluav taws.
