Nanopowder shanu-zvakajairika electromagnetic shielding zvinhu

Parizvino, inonyanya kushandiswa ndeye composite electromagnetic shielding coatings, kuumbwa kwacho kunonyanya kuumba firimu resin, conductive filler, diluent, coupling agent uye zvimwe zvinowedzera.Pakati pavo, conductive filler chinhu chakakosha.Sirivha hupfu uye hupfu hwemhangura , nickel poda, sirivha yakavharwa poda yemhangura, kabhoni nanotubes, graphene, nano ATO uye zvichingodaro zvinowanzoshandiswa.

1.Carbon nanotube

Carbon nanotubes ine yakakura chimiro ratio uye yakanakisa magetsi uye magineti zvivakwa, uye inoratidza kuita kwakanakisa mumagetsi uye inonwisa nhovo.Naizvozvo, kuwedzera kukosha kunobatanidzwa mukutsvagisa uye kusimudzira mafiritsi emagetsi semagetsi ekudzivirira machira.Izvi zvine zvakakwirira zvinodiwa pakuchena, kugadzirwa uye mutengo wecarbon nanotubes.Iyo kabhoni nanotubes inogadzirwa neHongwu Nano Factory, inosanganisira imwe-yakavakirwa uye yakawanda-yakavakirwa CNTs, ine kuchena kunosvika 99%.Kupararira kwekabhoni nanotubes mune matrix resin uye kana iine hukama hwakanaka nematrix resin inova chinhu chakananga chinokanganisa mashandiro ekudzivirira.Hongwu Nano inopawo yakaparadzirwa kabhoni nanotube dispersion solution.

2. Low Bulk Density uye yakaderera SSAflake sirivheri poda

Iwo ekutanga anowanikwa paruzhinji ma conductive coatings aive patented muUnited States muna 1948 kugadzira zvinonamira zvinogadzirwa nesirivheri uye epoxy.Iyo pendi yemagetsi yekudzivirira inogadzirwa nebhora-yakagayiwa sirivheri poda inogadzirwa naHongwu Nano ine hunhu hwekupokana nemagetsi, kunaka kwemagetsi conductivity, kukwirira kwekudzivirira, kwakasimba kuramba kwezvakatipoteredza uye kuvaka kuri nyore.Inoshandiswa zvakanyanya mukutaurirana, zvemagetsi, zvekurapa, aerospace, zvivakwa zvenyukireya uye mamwe minda yekudzivirira pendi inokodzerawo ABS, PC, ABS-PCPS uye humwe huinjiniya hwepurasitiki hwepamusoro.Zviratidzo zvekushanda zvinosanganisira kupfeka kuramba, yakakwirira uye yakaderera tembiricha kuramba, kupisa uye humidity kuramba, adhesion, magetsi resistivity, uye electromagnetic kuenderana.

3. Upfu hwemhangurauyenickel powder

Copper poda conductive coatings yakaderera mumutengo, iri nyore kuisa, ine yakanaka electromagnetic shielding effect, uye inoshandiswa zvakanyanya.Iwo akanyanya kukodzera kukanganiswa kwemagetsi emagetsi ezvigadzirwa zvemagetsi nemapurasitiki einjiniya segoko, nekuti pendi yemhangura yehupfu inogona kupfapfaidzwa zviri nyore kana kubhurashwa pamhando dzakasiyana dzepurasitiki dzinoshandiswa kugadzira pamusoro, uye nzvimbo yepurasitiki inogadzirwa nesimbi kuti iite electromagnetic shielding conductive layer, kuitira kuti purasitiki iwane chinangwa chekudzivirira mafungu emagetsi.Chimiro uye huwandu hwehupfu hwemhangura zvine simba guru pane conductivity yekuputira.Hupfu yemhangura ine spherical shape, dendritic shape, sheet shape nezvimwe zvakadaro.Iro shiti rakakura zvakanyanya kupfuura spherical yekuonana nzvimbo uye rinoratidza zvirinani conductivity.Mukuwedzera, poda yemhangura (silver-coated copper powder) yakafukidzwa nesimbi isingashande sirivha poda, iyo isiri nyore kuve oxidized.Kazhinji, zviri mukati mesirivha ndeye 5-30%.Copper poda conductive coating inoshandiswa kugadzirisa electromagnetic shielding yeinjiniya mapurasitiki uye huni senge ABS, PPO, PS, etc. Uye matambudziko ekuitisa, ane huwandu hwakawanda hwekushandisa uye kukosha kwekusimudzira.

Uye zvakare, iyo electromagnetic shielding yekubudirira kuyerwa mhedzisiro yemagetsi ekudzivirira machira akasanganiswa ne nano-nickel poda uye nano-nickel poda uye micro-nickel poda inoratidza kuti kuwedzera kwenano-nickel poda kunogona kuderedza kushanda kwemagetsi ekudzivirira, asi kunogona kuwedzera kurasikirwa kwekutora nekuda kwekuwedzera.Iyo magineti kurasikirwa tangent inoderedza kukuvadzwa kunokonzerwa nemagetsi mafungu kune zvakatipoteredza uye zvishandiso uye kukuvadza kuhutano hwevanhu.

4. NanoATOTin oxide

Seyakasarudzika mafirita, nano-ATO poda ine yakakwira kujeka uye conductivity, uye ine yakafara maapplication mukuratidzira coating materials, conductive antistatic coatings, transparent thermal insulation coatings nemimwe minda.Pakati peiyo optoelectronic mudziyo inoratidzira coating materials, ATO zvinhu zvine anti-static, anti-glare uye anti-radiation mabasa, uye zvakatanga kushandiswa semagetsi ekudzivirira ekuvhara zvinhu zvekuratidzira.Nano ATO yekupfekedza zvinhu zvine yakanaka mwenje ruvara kujeka, yakanaka magetsi conductivity, simba remuchina uye kugadzikana.Ndiyo imwe yeakanyanya kukosha maindasitiri ekushandisa kweATO zvinhu mumidziyo yekuratidzira.Electrochromic zvishandiso, sezviratidziro kana smart windows, chinhu chakakosha chezvino nano ATO application mumunda wekuratidzira.

5. Graphene

Sechinhu chitsva chekabhoni, graphene inogona kunge iri nyowani inoshanda yemagetsi kudzivirira kana microwave inonwisa zvinhu kupfuura kabhoni nanotubes.Zvikonzero zvikuru zvinosanganisira zvinotevera:

Iko kunatsiridzwa kwekuita kwemagetsi ekudzivirira uye kunwisa zvinhu kunoenderana nezviri mukati meiyo inonwisa mumiriri, zvimiro zvemumiririri anonwisa uye yakanaka impedance inoenderana neiyo inonwisa substrate.Graphene haingove neyakasiyana chimiro chemuviri uye yakanakisa mechanical uye electromagnetic zvivakwa, asiwo ine yakanaka microwave absorption zvivakwa.Kana yakabatanidzwa nemagnetic nanoparticles, chinhu chitsva chinotora chinogona kuwanikwa, icho chine zvese kurasikirwa kwemagineti uye kurasikirwa kwemagetsi.Iyo ine yakanaka application tarisiro mumunda we electromagnetic shielding uye microwave absorption.
