Kev sib piv ntawm Cov Teeb Meem Tiv Thaiv Kev Ua Haujlwm
Taw qhia
Kev tiv thaiv hluav taws xob yog qhov tseem ceeb rau kev tiv thaiv cov khoom siv hluav taws xob tsis zoo los ntawm electromagnetic cuam tshuam (EMI) thiab xov tooj cua cuam tshuam (RFI). Kab lus no muab kev sib piv zoo ntawm peb cov khoom siv feem ntau-galvanized phaj, steel phaj, thiab txhuas phaj- soj ntsuam lawv cov khoom, kev ua tau zoo, thiab kev siv tau zoo hauv kev tsim hluav taws xob enclosure.
Khoom Properties & Shielding Mechanisms
Hlau Phaj
Ua los ntawm cov pa roj carbon steel, nws pom muaj qhov sib nqus permeability siab (μᵣ ib ncig ntawm 200-}1000) thiab robustness. Nws lub zog tseem ceeb yog nyob rau hauv absorbing tsawg- zaus sib nqus teb, ua rau nws zoo tagnrho rau cov ntawv thov uas muaj ntau zaus EMI.
Cov kev txwv muaj xws li susceptibility rau xeb thiab ntau dua ntom piv rau txhuas.
Aluminium Phaj
Tsis yog-ferrous nrog cov khoom siv hluav taws xob zoo (≈3.5 × 10⁷ S / m) thiab qhov ntom ntom (2.7 g / cm³). Nws ua tau zoo ntawm kev xav txog siab - zaus electromagnetic nthwv dej, ua tiav kev tiv thaiv zoo tshaj plaws ntawm GHz ntau yam.
Cov txiaj ntsig muaj xws li kev tsim lub teeb yuag, ntuj tiv thaiv corrosion ntawm tus kheej - kho oxide zaj duab xis, thiab rov ua dua tshiab.
Galvanized phaj
Hlau phaj coated nrog zinc ntawm kub-dip galvanization, sib txuas cov hlau nplaum tiv thaiv nrog kev txhim kho corrosion. Lub zinc txheej ua raws li kev fij tseg, tiv thaiv xeb yam tsis muaj kev hloov pauv cov khoom siv hauv paus.
Muab kev tiv thaiv kev ua tau zoo piv rau cov hlau tsis kho (dhau 60 dB hauv 100 MHz-1 GHz ntau) nrog kev txhim kho durability nyob rau hauv ib puag ncig hnyav.

Kev Ntsuas & Cov Qauv
Kev ua haujlwm tiv thaiv kev ua haujlwm yog tus qauv raws li ASTM D4935 lossis IEEE 299, siv cov kab sib txuas sib txuas lossis cov chaw reverberation los ntsuas kev tiv thaiv kev ua tau zoo (SE).
Cov ntsiab lus tseem ceeb ntawm kev xeem:
1. Aluminium phaj outperforms ntawm GHz zaus
2. Hlau thiab galvanized daim hlau ua tau zoo ntawm MHz ntau thiab hauv qab
3. Seam tsim (welded vs. gasketed) cuam tshuam kev ua tau zoo
Xaus
Kev xaiv ntawm cov khoom yog nyob ntawm cov kev xav tau tshwj xeeb: steel phaj rau qis- zaus sib nqus shielding, aluminium phaj rau siab- zaus thiab qhov hnyav- cov ntawv siv rhiab heev, thiab galvanized phaj rau corrosion-ib puag ncig xav tau kev ua haujlwm sib luag. Hybrid le caag (xws li, txhuas sab saum toj panels nrog galvanized bases) feem ntau optimize tus nqi, durability, thiab shielding efficiency.Raws li cov khoom siv hluav taws xob hloov zuj zus, kev tshawb fawb tsis tu ncua rau hauv cov ntaub ntawv sib xyaw txuas ntxiv ua kom zoo dua cov teeb liab thaiv kev daws teeb meem rau lub ntiaj teb kev sib txuas ntxiv.
