Nrog rau txoj kev loj hlob sai ntawm cov cuab yeej siv hluav taws xob, cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob ntau dua tau siv rau hauv tib neeg kev tsim khoom thiab lub neej. Khoos phib tawj, xov tooj cua thiab lwm yam khoom siv kis tau tus mob electromagnetic nthwv dej sib txawv wavelengths thiab frequencies. Electromagnetic pollution yog ib qho tshiab ntawm cov pa phem tom qab huab cua muaj kuab paug, dej muaj kuab paug thiab suab nrov. Yog li ntawd, ntau thiab ntau xim yog them rau electromagnetic shielding ntawm lwm yam khoom siv.
Electromagnetic shielding yog siv cov khoom siv hluav taws xob tiv thaiv hluav taws xob xws li hlau los ua lub cev tiv thaiv, txhawm rau txhawm rau txhawm rau txhawm rau tiv thaiv thaj chaw, thiab cais cov hluav taws xob hluav taws xob los ntawm lub cev tiv thaiv. Tiv thaiv. Thaum cov mem tes tuaj txog, lub zog hluav taws xob ntawm daim thaiv yuav raug cuam tshuam, absorbed los yog thaiv. Txawm hais tias electromagnetic nthwv dej tuaj yeem nkag mus rau hauv cov ntaub thaiv npog, lub zog hluav taws xob thiab hluav taws xob hluav taws xob yog attenuated mus rau qib siab.
Electromagnetic shielding yog ib qho ntawm cov kev ntsuas tseem ceeb los tiv thaiv cov khoom siv hluav taws xob thiab cov tshuab hluav taws xob los ntawm kev cuam tshuam ntawm electromagnetic. Nws tuaj yeem txo qhov cuam tshuam ntawm electromagnetic cuam tshuam los ntawm qhov chaw nthuav tawm. Nws tuaj yeem txo cov hluav taws xob EMI ntawm cov khoom siv hluav taws xob thiab tiv thaiv kev cuam tshuam ntawm sab nraud electromagnetic cuam tshuam ntawm cov khoom siv hluav taws xob.
Raws li cov khoom siv tshwj xeeb, tus neeg xyuas pib nws tus kheej tsis tsuas yog muaj hluav taws xob conductivity, tab sis kuj tuaj yeem tiv thaiv electromagnetic tsis. Txawm li cas los xij, hauv kev siv cov khoom siv niaj hnub no, kev tiv thaiv kev tiv thaiv ntawm cov ntaub ntawv no tseem yuav cuam tshuam los ntawm qee yam cuam tshuam, xws li kev cuam tshuam ib puag ncig, zaus, kev siv, thiab lwm yam, thiab cov nyhuv shielding ntawm electromagnetic vuag yuav txawv thaum siv.

1. Cov ntsiab lus
Raws li rau cov ntaub ntawv ntawm conductive daim ntaub, nws yog ib tug kuj tiav conductive khoom nws tus kheej; Yog li ntawd, cov khoom siv no tuaj yeem raug khi rau txhua qhov chaw hlau, thiaj li ua kom ntseeg tau tias tom qab kev sib txuas, cov khoom siv hluav taws xob sib khi ntawm cov hluav taws xob sib txuas kuj tuaj yeem txhim kho. Tiv thaiv lub luag haujlwm ntawm electromagnetic signals.

2. Scope ntawm daim ntawv thov
Lub kaw lus muaj cov yam ntxwv ntawm kev tiv thaiv electromagnetic signals thiab muaj ntau yam kev siv. Nws tuaj yeem siv dav hauv qee qhov chaw muaj zog hluav taws xob uas yuav tsum tau tiv thaiv hluav taws xob hluav taws xob, xws li ua cov khaub ncaws tiv thaiv kev ua haujlwm, kev tiv thaiv chav ua cov ntaub thaiv npog, cov hnab looj tes tiv thaiv, cov ntaub thaiv hluav taws xob thiab lwm yam khoom.

3. Ua npuas ncauj
Ntxiv rau qhov tsim nyog rau qee thaj chaw uas yuav tsum tau tiv thaiv cov cim hluav taws xob, qhov system no kuj tuaj yeem siv rau EMI / EMC tswj ntawm ntau yam khoom siv hluav taws xob. Thaum npaj cov khoom ntawm cov paj rwb ua npuas ncauj, nws tsuas yog tsim nyog los qhwv nws nyob rau hauv lub siab elastic ib feem ntawm lub npaus, thiab txiav nws mus rau hauv txawv duab thiab ntau thiab tsawg pab raws li sib txawv xav tau kev pab nyob rau hauv tus txheej txheem ntawm kev siv, kom ntseeg tau tias sib txawv kev xav tau kev pab, thiab yuav ua tau. Cov duab sib thooj, cov txheej txheem ntau lawm yog qhov yooj yim heev. Vim tias cov khoom siv tuaj yeem hloov nws cov duab raws li qhov xav tau, nws tsis tsuas yog muaj ntau yam kev siv, tab sis kuj muaj zog adaptability.
