Ma nanopowder asanu - zida zodzitchinjiriza za electromagnetic

Pakadali pano, zomwe zimagwiritsidwa ntchito kwambiri ndi zokutira zotchingira zamagetsi zophatikizika, zomwe zimapangidwa makamaka ndi utomoni wopanga filimu, ma conductive filler, diluent, coupling agent ndi zina.Pakati pawo, conductive filler ndi gawo lofunikira.Silver ufa ndi mkuwa ufa, faifi tambala, siliva wokutidwa mkuwa ufa, carbon nanotubes, graphene, nano ATO ndi zina zotero.

1.Mpweya wa carbon nanotube

Ma carbon nanotubes ali ndi chiyerekezo chachikulu komanso mphamvu zabwino kwambiri zamagetsi ndi maginito, ndipo amawonetsa magwiridwe antchito abwino kwambiri pamagetsi ndi zishango zoyamwa.Chifukwa chake, kufunikira kowonjezereka kumalumikizidwa ndi kafukufuku ndi chitukuko cha ma conductive fillers ngati zokutira zotchingira ma electromagnetic.Izi zili ndi zofunika kwambiri pa chiyero, zokolola ndi mtengo wa carbon nanotubes.Ma carbon nanotubes opangidwa ndi Hongwu Nano Factory, kuphatikiza ma CNT okhala ndi mipanda imodzi komanso okhala ndi mipanda yambiri, amakhala ndi chiyero mpaka 99%.Kubalalika kwa carbon nanotubes mu resin ya matrix komanso ngati ili ndi mgwirizano wabwino ndi utomoni wa matrix imakhala chinthu chachindunji chomwe chimakhudza magwiridwe antchito.Hongwu Nano imaperekanso njira yobalalitsira mpweya wa nanotube.

2. Low Bulk Density ndi SSA yochepaflake silver powder

Zovala zoyambirira zomwe zidapezeka poyera zinali zovomerezeka ku United States mu 1948 kuti apange zomatira zasiliva ndi epoxy.Utoto wotchinga ma elekitiroma wokonzedwa ndi ufa wopangidwa ndi siliva wopangidwa ndi Hongwu Nano uli ndi mawonekedwe amagetsi ang'onoang'ono, madulidwe abwino amagetsi, chitetezo chokwanira, kukana kwamphamvu kwa chilengedwe komanso zomangamanga zosavuta.Amagwiritsidwa ntchito kwambiri muzoyankhulana, zamagetsi, zamankhwala, zakuthambo, zida za nyukiliya ndi magawo ena a utoto wotchinga ndizoyeneranso kwa ABS, PC, ABS-PCPS ndi zokutira zina zamapulasitiki.Zizindikiro zogwirira ntchito zimaphatikizapo kukana kuvala, kukana kutentha kwambiri komanso kutsika, kukana kutentha ndi chinyezi, kumamatira, kukana kwamagetsi, komanso kuyanjana kwamagetsi.

3. Mkuwa wa ufandinickel ufa

Zovala za Copper powder conductive ndizotsika mtengo, zosavuta kugwiritsa ntchito, zimakhala ndi chitetezo chabwino chamagetsi, ndipo zimagwiritsidwa ntchito kwambiri.Ndiwoyenera makamaka kusokoneza mafunde amagetsi amagetsi okhala ndi mapulasitiki a uinjiniya ngati chipolopolo, chifukwa utoto wopangira ufa wa mkuwa ukhoza kupopera mosavuta kapena kupaka utoto pamitundu yosiyanasiyana ya pulasitiki yomwe imagwiritsidwa ntchito popanga pamwamba, ndipo pulasitiki pamwamba pake imapangidwa ndi zitsulo. electromagnetic shielding conductive layer, kuti pulasitiki ikwaniritse cholinga choteteza mafunde a electromagnetic.Maonekedwe ndi kuchuluka kwa ufa wamkuwa zimakhudza kwambiri ma conductivity a zokutira.Ufa wamkuwa uli ndi mawonekedwe ozungulira, mawonekedwe a dendritic, mawonekedwe a pepala ndi zina zotero.Tsambali ndi lalikulu kwambiri kuposa malo ozungulira ozungulira ndipo likuwonetsa kuwongolera bwino.Kuonjezera apo, ufa wa mkuwa (ufa wa siliva-wokutidwa ndi siliva) umakutidwa ndi chitsulo chosagwira ntchito cha siliva ufa, chomwe sichapafupi kukhala oxidized.Nthawi zambiri, zomwe zili siliva ndi 5-30%.Copper ufa conductive ❖ kuyanika ntchito kuthetsa electromagnetic chitetezo cha mapulasitiki zomangamanga ndi matabwa monga ABS, PPO, PS, etc. Ndipo mavuto conductive, ndi osiyanasiyana ntchito ndi mtengo Kukwezeleza.

Kuphatikiza apo, zotsatira za kuyeza kwamphamvu kwamagetsi oteteza ma electromagnetic zotchingira zotchingira zamagetsi zosakanikirana ndi ufa wa nano-nickel ndi ufa wa nano-nickel ndi ufa wawung'ono wa faifi tambala zikuwonetsa kuti kuwonjezera kwa nano-nickel ufa kumatha kuchepetsa mphamvu yamagetsi yotchinga, koma kumatha kukulitsa kuchepa kwa mayamwidwe chifukwa cha kuchuluka.Magnetic loss tangent amachepetsa kuwonongeka komwe kumachitika chifukwa cha mafunde a electromagnetic ku chilengedwe ndi zida komanso kuvulaza thanzi la anthu.

4. NanoATOTin oxide

Monga chojambulira chapadera, ufa wa nano-ATO umakhala wowonekera kwambiri komanso wowoneka bwino, ndipo umakhala ndi ntchito zambiri pazida zowonetsera, zokutira zoteteza antistatic, zokutira zowoneka bwino zamafuta ndi magawo ena.Pakati pa zida zopangira ma optoelectronic zida zokutira, zida za ATO zili ndi anti-static, anti-glare ndi anti-radiation, ndipo zidayamba kugwiritsidwa ntchito ngati zida zokutira zotchingira ma electromagnetic zowonetsera.Zida zokutira za Nano ATO zili ndi mawonekedwe owoneka bwino amtundu wowala, kuwongolera bwino kwamagetsi, mphamvu zamakina komanso kukhazikika.Ndi imodzi mwamafakitale ofunikira kwambiri a zida za ATO pazida zowonetsera.Zipangizo zamagetsi, monga zowonetsera kapena mawindo anzeru, ndizofunikira kwambiri pakugwiritsa ntchito nano ATO pagawo lowonetsera.

5. Graphene

Monga zinthu zatsopano za kaboni, graphene imatha kukhala chotchinga chatsopano chamagetsi kapena chotengera ma microwave kuposa ma carbon nanotubes.Zifukwa zazikulu ndi izi:

Kuwongolera kwa magwiridwe antchito a electromagnetic shielding ndi zinthu zoyamwa zimatengera zomwe zimayamwa, zomwe zimayamwa komanso kufananiza kwabwino kwa gawo lapansi loyamwa.Graphene sikuti imakhala ndi mawonekedwe apadera komanso mawonekedwe abwino kwambiri amakina ndi ma elekitiroma, komanso imakhala ndi mayamwidwe abwino a microwave.Kuphatikizidwa ndi maginito nanoparticles, chinthu chatsopano choyamwa chingathe kupezedwa, chomwe chimakhala ndi maginito otayika komanso kutaya magetsi.Ili ndi chiyembekezo chogwiritsa ntchito bwino pachitetezo chamagetsi ndi mayamwidwe a microwave.
