Kodi mukudabwa chifukwa chake Copper foil ndiye chinthu chabwino kwambiri chotetezera?

Kusokoneza kwa maginito ndi ma radio-frequency (EMI/RFI) ndi vuto lalikulu pa ma waya otetezedwa omwe amagwiritsidwa ntchito potumiza deta. Kusokonezeka kochepa kwambiri kungayambitse kulephera kwa chipangizo, kuchepa kwa khalidwe la chizindikiro, kutayika kwa deta, kapena kusokonezeka kwathunthu kwa ma waya otetezedwa. Kuteteza, komwe ndi gawo la insulation lomwe lili ndi mphamvu zamagetsi ndipo limazunguliridwa ndi chingwe chamagetsi kuti lilepheretse kutulutsa kapena kuyamwa EMI/RFI, ndi gawo la ma waya otetezedwa. Njira zotetezera zomwe zimagwiritsidwa ntchito kwambiri, ndi "kuteteza zojambulazo" ndi "kuteteza kolukidwa."

Chingwe chotetezedwa chomwe chimagwiritsa ntchito utoto wochepa wa mkuwa kapena aluminiyamu kuti chikhale ndi moyo wautali chimadziwika kuti kutchingira zojambulazo. Waya wothira madzi a mkuwa wopangidwa ndi zitini ndi chishango cha zojambulazo zimagwira ntchito limodzi kuti chishangocho chigwe pansi.

Ubwino wogwiritsa ntchito mkuwa ngati zojambulazo ndi zotchingira zoluka

Mitundu iwiri yotchuka kwambiri ya zingwe zotchingira zomwe zimagwiritsidwa ntchito m'mafakitale ndi zojambula ndi zoluka. Mitundu yonse iwiri imagwiritsa ntchito mkuwa. Zotchingira zojambulazo zimapereka chitetezo chokwanira ndipo zimalimbana ndi ma RFI ambiri. Zotchingira zojambulazo ndi zachangu, zotsika mtengo, komanso zosavuta kupanga chifukwa ndi zopepuka komanso zotsika mtengo.

Zishango za ukonde ndi zoluka zathyathyathya zonse zimapezeka. Panthawi yopanga, zoluka zathyathyathya zopangidwa ndi mkuwa wopangidwa ndi zitini zimakulungidwa mu zoluka. Kusinthasintha kwake kwakukulu kumapangitsa kuti zikhale zoteteza bwino kwambiri pamapayipi ndi machubu. Zingagwiritsidwe ntchito ngati lamba wolumikizira zida zamagalimoto, ndege, ndi zombo komanso zingwe zotetezera, zingwe zomangira pansi, kuyika batire pansi, ndi kuyika batire pansi. Ndizoyenera kugwiritsa ntchito kulikonse komwe kumafuna kuluka kwa mkuwa wopangidwa ndi zitini komanso kuchotsa kusokoneza kwa kuyaka. Chishango chochepera 95% chimaphimbidwa ndi mkuwa wopangidwa ndi zitini. Zishango zamkuwa zolukidwa zimakwaniritsa zofunikira za ASTM B-33 ndi QQ-W-343 mtundu S.

Matepi a foil a mkuwaGuluu woyendetsa magetsi ndi wabwino kwambiri posintha ma circuit board osindikizidwa, kukonza ma alarm circuits achitetezo, ndikuyika ndikupanga ma prototypes a wiring board. Ndi wabwino kwambiri pakukulunga chingwe cha EMI/RFI komanso kuonetsetsa kuti magetsi akupitilizabe polumikizana ndi zipinda zotetezedwa za EMI/RFI. Kuphatikiza apo, imagwiritsidwa ntchito polumikizana ndi zinthu zosasungunuka monga pulasitiki kapena aluminiyamu ndikutulutsa magetsi osasinthika. Mtundu wake wowala ngati mkuwa umapangitsa kuti ukhale woyenera ntchito zaluso ndi zaluso chifukwa sudzawonongeka. Pepala lopyapyala la mkuwa kapena aluminiyamu limagwiritsidwa ntchito poteteza zojambulazo. Nthawi zambiri, "foil" iyi imalumikizidwa ku chonyamulira cha polyester kuti iwonjezere mphamvu ya chingwe. Mtundu uwu wa chingwe chotetezedwa, chomwe chimatchedwanso "tepi" shielding, chimateteza kwathunthu waya wa conductor womwe wazunguliridwa. Palibe EMI kuchokera ku chilengedwe yomwe ingalowe. Komabe, zingwe izi zimakhala zovuta kwambiri kuthana nazo, makamaka mukamagwiritsa ntchito cholumikizira, chifukwa zojambulazo mkati mwa chingwe ndi zofewa kwambiri. M'malo moyesa kumiza chishango cha chingwe kwathunthu, waya wotulutsa madzi nthawi zambiri amagwiritsidwa ntchito.

Chishango cha mkuwa chopaka utoto chimalangizidwa kuti chiteteze kwambiri chishango. Chishango chake chopaka utoto chochepera 95% chimaperekedwa chifukwa cha kapangidwe kake ka mkuwa wopangidwa ndi chitini. Ndi chosinthasintha kwambiri ndipo chili ndi makulidwe ochepa a.020″, zomwe zimapangitsa kuti chikhale choyenera kugwiritsidwa ntchito ngati lamba wolumikizira zida zapamadzi, magalimoto, ndi ndege.

Mawaya a mkuwa amalukidwa mu ulusi wa zingwe zotetezedwa ndi kuluka. Ngakhale kuti siziteteza kwambiri kuposa zishango za foil, zishango zolukidwa zimakhala zolimba kwambiri. Pogwiritsa ntchito cholumikizira, ulusiwo ndi wosavuta kuuthetsa ndipo umapanga njira yolimba yochepetsera kuuma. Kutengera momwe ulusiwo walukidwira mwamphamvu, ulusi wolukidwa nthawi zambiri umapereka chitetezo cha 70 mpaka 95 peresenti cha EMI. Chifukwa chakuti mkuwa umatulutsa magetsi mwachangu kuposa aluminiyamu ndipo chifukwa zishango zolukidwa sizingawonongeke mkati, zimakhala zothandiza kwambiri kuposa zishango za foil. Chifukwa cha kugwira ntchito bwino komanso kulimba kwawo, zishango zolukidwa zimakhala zolemera komanso zodula kuposa zishango za tepi.

Kampani yathu,Chitsulo cha Civen, tinapanga makina abwino kwambiri opangira ndi kupanga mizere yolumikizirana padziko lonse lapansi, komanso gulu lalikulu la akatswiri komanso akatswiri komanso gulu loyang'anira zinthu zapamwamba. Timatsatira njira ndi miyezo yapadziko lonse lapansi yosankha zinthu, kupanga, kuwongolera khalidwe, kulongedza, ndi mayendedwe. Kuphatikiza apo, timatha kuchita kafukufuku wodziyimira pawokha ndikupanga zipangizo zapadera zachitsulo kwa makasitomala.

Mukhoza kupita patsamba lathu (lomwe lili pansipa), kuti mudziwe zambiri zokhudza tepi ya foil, ndi zotchingira mkuwa zopangidwa ndi zitini, kapena mutha kutiyimbira foni kuti tikuthandizeni.
