Njira yopanga: Elastomer Yopangidwa ndi Yowonjezera
EMI zoteteza elastomer mankhwala amapangidwa makamaka ndi akamaumba ndi extrusion.
Conductive elastomer molding (extrusion) process flow chart:
Kupyolera mu njira yopangira, EMI yotsekereza elastomer imatha kupangidwa kukhala ma sheet opangira mphira, ma gaskets ndi ma gaskets opangira mphira. Ma gaskets amatha kusinthidwa kukhala mawonekedwe osiyanasiyana malinga ndi zojambulazo. Kudzera mu njira extrusion, EMI kutsekereza elastomer akhoza kupangidwa zosiyanasiyana mosalekeza n'kupanga mphira n'kupanga zonse conductive n'kupanga mphira n'kupanga. Magawo am'mbali mwa mizereyo ndi amakona anayi, ozungulira, "D" -woboola, "U" -woboola, "P" -woboola, "M" -woboola, "B" -woboola, obowola "B" -woboola pakati, ndi mitundu ingapo yopyapyala, kapena malupu otsekedwa amitundu yosiyanasiyana akhoza kusinthidwa mwachindunji kuchokera ku kampani.
Zida zazikulu zopangira zikuphatikizapo chosakanizira chamkati, chosakanizira chotseguka, extruder, vulcanizer yathyathyathya.
Mtundu wa EMI shielding conductive elastomer
EMI kutchingira conductive elastomer kuumbidwa gasket
Ma gaskets oyendetsa ndi zinthu zopangidwa ndipo amatha kugawidwa m'mambale, ma gaskets olumikizira, ma O-rings gaskets, ma waveguide flange gaskets, ndi ma gaskets ooneka ngati apadera malinga ndi mawonekedwe awo.
- Mawonekedwe￭Low volume resistivity
￭High electromagnetic shielding mphamvu
￭Mkulu wamakokedwe mphamvu ndi elongation pa nthawi yopuma
￭Wide ntchito kutentha osiyanasiyana
￭Zabwino kukana dzimbiri
￭Moyo wautali wautumiki
EMI kutchinga magalasi otulutsa elastomer owonjezera
Ma conductive n'kupanga amakhala ndi mawonekedwe otsika kachulukidwe, kupindika kwakukulu, kutalika kosalekeza komanso kudula kosasintha. Kupyolera m'mapangidwe amitundu yosiyanasiyana, kuponderezana kwa zinthu pakati pa nyumba zamagetsi kumatha kusinthidwa kuti zigwirizane ndi ntchito za msonkhano wa uinjiniya m'malo osiyanasiyana. Mizere yopangira ma conductive ndi zinthu zopangira ma extrusion, ndipo mawonekedwe ake amatha kugawidwa kukhala olimba komanso opanda kanthu. Izi makamaka zimaphatikizapo: olimba oboola pakati, olimba amakona anayi, olimba D-woboola pakati, dzenje O-woboola pakati, dzenje amakona anayi, dzenje P woboola pakati, dzenje D woboola pakati, U-woboola, etc.
- Mawonekedwe:￭Good magetsi madutsidwe
￭Kutalika kosalekeza ndipo kumatha kudulidwa mwakufuna￭Kugonjetsedwa ndi chinyezi ndi kutentha￭Moyo wautali wautumiki￭Kuteteza kwakukulu￭Wide ntchito kutentha osiyanasiyana￭Zabwino kukana dzimbiri
EMI kutchinga ma gaskets osindikiza a elastomer
Kusindikiza kosindikiza kwa elastomer kumapangidwa pophatikiza magawo oyendetsa komanso osagwiritsa ntchito njira yapadera. Gawo la conductive limapangitsa kuti zinthuzo zikhale ndi ma conductivity abwino, pomwe zotanuka kwambiri zomwe sizimayendetsa zimapangitsa kuti zinthuzo zikhale ndi ntchito yabwino yosindikiza mpweya wamadzi. Mphamvu yolumikizana mwamphamvu pakati pa magawo awiriwa imapangitsa kuti zikhale zovuta kuchotsa mawonekedwe azinthuzo. Composite conductive rabara imakhala ndi mphamvu yopondereza kwambiri, ndipo kapangidwe kake kapadera kamapangitsa kuti ikhale yolimbana ndi dzimbiri yamchere komanso kukana mildew.
- Mawonekedwe￭Ochepa kachulukidwe
￭Zabwino kwambiri psinjika seti ndi madzi nthunzi kusindikiza katundu
￭Kumanani ndi mulingo wapamwamba wosalowa madzi komanso magwiridwe antchito abwino amagetsi amagetsi
￭Mphamvu yabwino yokhazikika komanso kutalika kwa nthawi yopuma
￭Kupanikizika kwakukulu, mpaka 15% mpaka 60%
￭Easy compress ndi kukhazikitsa
￭Wide ntchito kutentha osiyanasiyana
￭Zabwino kukana dzimbiri
￭Moyo wautali wautumiki
Kusankhidwa kwa zida zopangira mphira
Siliva wangwiro & mphira wa silikoni: odana ndi nkhungu, oyenera mikhalidwe yomwe imalepheretsa kukula kwa tizilombo tating'onoting'ono, yokhala ndi chitetezo chabwino kwambiri komanso kuwongolera, komanso mawonekedwe abwino.
Galasi wokutidwa ndi siliva & mphira wa silikoni: chiŵerengero chabwino kwambiri cha mtengo wogwira ntchito, choyenera malo olankhulana ndi zochitika zankhondo wamba, ndikuchita bwino m'malo osawononga.
Mkuwa wokutidwa ndi siliva & mphira wa silikoni: woyendetsa bwino kwambiri, wosamva kukhudzidwa kwa EMP, woyenera pazochitika zankhondo, ndipo angagwiritsidwe ntchito ngati gasket wamafunde ndi zolumikizira.
Aluminiyamu wokutidwa ndi siliva & silikoni mphira: chitetezo chokwanira, electrochemically yogwirizana ndi aluminium chassis, ma gaskets ankhondo amagwiritsidwa ntchito m'malo owononga, ndipo ndi opepuka, ndipo amagwiritsidwa ntchito kwambiri popanga ma gaskets osindikizira osiyanasiyana.
Aluminiyamu wokutidwa ndi siliva & fluorosilicone mphira: chitetezo chokwanira, kukana kwa dzimbiri, kukana kwamafuta ambiri, kumatha kusintha kwambiri kudalirika ndi moyo wautumiki wa chinthucho.
graphite faifi tambala-yokutidwa & silikoni mphira: mtengo wotsika, wabwino electrochemical ngakhale ndi aluminiyamu, ndipo ali madutsidwe mkulu ndi kusindikiza bwino chilengedwe, amene angagwiritsidwe ntchito mankhwala wamba asilikali.
Mpweya wapamwamba kwambiri wa carbon & silikoni: Umapereka chitetezo chotsika, mphamvu yabwino yokhazikika, yosagonjetsedwa ndi dzimbiri, imatha kusunga zinthu zakuthupi ndi zamagetsi pa kutentha kwakukulu, ndipo ndi yabwino kwambiri kuti igwiritsidwe ntchito mu electrostatic discharge kapena corona discharge.
