Magirazi madiki asina chinhu magirazi madiki akagadziriswa, ayo anonyanya kuzivikanwa nekudzikira kwehuwandu uye kuderera kwekupisa kupfuura magirazi madiki. Imhando itsva yezvinhu zvakareruka zve micron-scale zvakagadzirwa muma1950 nema1960. Chinhu chikuru chayo iborosilicate, ine saizi yezvikamu zve10~250μm uye ukobvu hwemadziro hwe1~2μm; magirazi asina chinhu ane hunhu hwekusimba kwakanyanya kwekumanikidza, nzvimbo yakakwira yekunyunguduka, resistivity yakakwira, uye thermal conductivity diki uye thermal shrinkage coefficient. Inozivikanwa se "space age material" muzana remakore rechi21. Magirazi madiki asina chinhu Zvine huremu hwakadzika uye zvinodzivirira ruzha uye zvinodzivirira kupisa, kuitira kuti zvigadzirwa zvive nekushanda kwakanaka kwekudzivirira kupwanyika uye kugadzirisa patsva, uye zvinoshandiswa zvakanyanya muzvinhu zvakasanganiswa zvakaita sepurasitiki yakasimbiswa nefiber yegirazi, marble yekugadzira, agate yekugadzira, pamwe chete neindasitiri yepeturu, indasitiri yendege neyemuchadenga. , zvitima zvitsva zvinomhanya zvakanyanya, mota nengarava, machira ekudzivirira kupisa nezvimwe zvakasimudzira budiriro yemabasa esainzi netekinoroji enyika yangu. Kuti zvizadzise zvinodiwa nezvinhu zvekutaurirana zve5G zvine dielectric shoma, kurasikirwa kwakaderera uye huremu hwakareruka, magirazi madiki asina chinhu anoitawo basa rakakura nekuda kwemutengo wakaderera uye kushanda zvakanaka.
1 - Chinhu Chinosanganisa
Kuumbwa kwemakemikari emagirazi madiki asina chinhu (chiyero chehukuru)
SiO2: 50% -90%, Al2O3: 10% -50%, K2O: 5% -10%, CaO: 1% -10%, B2O3: 0-12%
2- Zvinhu Zvikuru
ruvara ruchena chaiko
Inogona kushandiswa zvakanyanya mune chero zvigadzirwa zvine zvinodiwa pakuonekwa uye ruvara.
3- kuwanda kwechiedza
Kuwanda kwemagirazi madiki egirazi ane hollow glass microspheres kunosvika chikamu chimwe mugumi chehuwandu hwezvinhu zvechinyakare zvinozadza. Mushure mekuzadza, huremu hwechigadzirwa hunogona kuderedzwa zvakanyanya, maresini akawanda ekugadzira anogona kutsiviwa uye kuchengetwa, uye mutengo wechigadzirwa unogona kuderedzwa.
4-Kugona Kuchinja-chinja kwemafuta mumuviri
Magirazi madiki asina chinhu ari nyore kunyorovesa nekuaparadzira, uye anogona kuzadzwa nemaresini akawanda ethermoplastic anoiswa muthermosetting, akadai sepolyester, epoxy resin, polyurethane, nezvimwewo.
5-Kuwana mari yakawanda zvakanaka
Sezvo magirazi madiki ari madiki, ane kuyerera kuri nani mumaresini emvura pane mafirita, tsono kana mafirita asina kujairika, saka ane mashandiro akanaka ekuzadza mold. Chinonyanya kukosha ndechekuti madiki madiki ari isotropic, saka hapana chakaipa chekusawirirana kwehuwandu hwekudonha muzvikamu zvakasiyana nekuda kwekutarisa, izvo zvinoita kuti chigadzirwa chigadzikane uye chisatendere.
6- Kudzivirira kupisa uye ruzha
Mukati memagirazi madiki madiki igesi rakatetepa, saka rine hunhu hwekudzivirira ruzha uye kupisa, uye rinozadza zvakanaka zvigadzirwa zvakasiyana-siyana zvekudzivirira kupisa uye kupisa ruzha. Hunhu hwekudzivirira hwemagirazi madiki madiki madiki hunogonawo kushandiswa kudzivirira zvigadzirwa kubva mukupiswa kunokonzerwa nekuchinjana pakati pekupisa nekukurumidza uye mamiriro ekutonhora nekukurumidza. Kudzivirira kwakanyanya uye kushoma kwemvura kunoita kuti ishandiswe zvakanyanya mukugadzira zvinhu zvekudzivirira tambo.
7- Kusanyorova kwemafuta
Zvidimbu zvebhora zvinoona kuti rine nzvimbo diki pane imwe chete uye mwero wakaderera wekunyudzwa kwemafuta. Munguva yekushandisa, huwandu hweresin hunogona kuderedzwa zvakanyanya, uye viscosity haizowedzera zvakanyanya kunyangwe paine huwandu hwakawanda hwekuwedzera, izvo zvinovandudza zvakanyanya kugadzirwa uye mashandiro. Wedzera kushanda zvakanaka kwekugadzira ne10% kusvika 20%.
8- Chinogara chichitenderera che dielectric chakaderera
Kukosha kweDk kwema microspheres egirazi risina chinhu i1.2 ~ 2.2 (100MHz), izvo zvinogona kuvandudza zvinobudirira hunhu hwe dielectric hwechinhu chacho.
Mapurasitiki ekugadzira magirazi asina chinhu
(1) Pakugadzirisa mapurasitiki einjiniya akadai senylon, PP, PBT, PC, POM, nezvimwewo, inogona kuvandudza kuyerera kwemvura, kubvisa kusvibiswa kwegirazi nefiber, kukunda warpage, kuvandudza mashandiro emoto anodzora moto, kuderedza kushandiswa kwegirazi nefiber, uye kuderedza mari yekugadzira.
(2) Kuzadza nePVC yakasimba, PP, PE, uye kugadzira zvinhu zvakagadzirwa, mapaipi nemaplate zvinogona kuita kuti zvigadzirwa zvive nekugadzikana kwakanaka, kuvandudza kuomarara uye kupisa kunodzivirira kupisa, kuvandudza mashandiro emitengo yezvigadzirwa, kuvandudza kushanda zvakanaka kwekugadzira uye kuderedza mitengo.
(3) Kuzadza PVC, PE nedzimwe tambo uye zvinhu zvinodzivirira kupisa zvinogona kuvandudza kusimba kwekupisa kwakanyanya kwechigadzirwa, kusimba kwekupisa, kusimba kweasidhi nealkali nezvimwe zvinhu uye mashandiro ekugadzirisa chigadzirwa, kuwedzera kubuda uye kuderedza mitengo.
(4) Kuzadza ndiro ye epoxy resin copper clad kunogona kuderedza viscosity ye resin, kuwedzera simba rekukotama, kuvandudza hunhu hwayo hwemuviri uye hwemakanika, kuwedzera tembiricha yekuchinja kwegirazi, kuderedza dielectric constant, kuderedza kunyudzwa kwemvura, uye kuderedza mutengo.
(5) Kuzadza nepolyester isina kuguta kunogona kuderedza mwero wekupwanyika uye mwero wemvura yekugeza yechigadzirwa, kunatsiridza kuramba kupera uye kuomarara, uye kuva nemakomba mashoma panguva yekuputira nekuvhara. Inoshandiswa kune zvigadzirwa zveFRP, mavhiri ekupolisha, maturusi, nezvimwewo.
(6) Kuzadza nesilicone resin kunogona kuvandudza hunhu hwemuviri uye hwemakanika, uye huwandu hwakawanda hwekuzadza hunogona kuderedza zvakanyanya mutengo, inova chinhu chakanakira kugadzira maforoma.
