Zvishandiso mumabhodhi edunhu akadhindwa
Mukugadzira maitiro eakadhindwa edunhu mabhodhi (akazozivikanwa sePCB), aramid fibers anoshandiswa kubatanidza yakakwirira-density yemagetsi chip lead inotsigira.Rudzi urwu rwerutsigiro rune simba rakasimba, saka rinogona kudzivirira mapepa emhangura uye resin substrates mushure mekupisa.matambudziko ekuparadzana.Muindasitiri yemagetsi, kushandiswa kwezvinhu zvearamid kugadzira mabhodhi ePCB kunogona kuwedzera kusimba uye kunaka kwemabhodhi edunhu.Rudzi urwu rwebhodhi redunhu rine saizi yakanaka uye coefficient yekuwedzera ye3×10-6/℃.Nekuda kweiyo yakaderera dielectric dhizaini yedunhu bhodhi, inokodzera kukwirisa-kumhanya kutapurirana kwemitsara.
Kuenzaniswa negirazi fiber zvinhu, kuwanda kweiyi bhodhi redunhu kunoderedzwa ne20%, nekudaro kuona chinangwa chekugadzira chehuremu huremu uye diki sisitimu yemidziyo yemagetsi.Imwe kambani yekuJapan yakagadzira bhodhi rePCB rine kugadzikana kuri nani, kuchinjika kwepamusoro, uye yakasimba inodzivirira hunyoro.Mukugadzira nzira,aramid fibersanoshandiswa mune meta-nzvimbo, iyo inokurumidza kugadzirira epoxy-based resin zvinhu.Kana ichienzaniswa nekushandiswa kwezvinhu zvakapesana, zviri nyore kugadzirisa uye zvine hunyoro hwekunyudza kuita.MaPCB akagadzirwa nearamid fibers akareruka muhuremu uye akasimba mukuita, uye anogona kushandiswa mumafoni nematablet makomputa.Pamusoro pezvo, mabhodhi ematunhu emazuva ano akavakirwa paaramid fiber ane ma-multi-layer structure anogona kurongedza ma-high-density electronics, ayo akakodzera kufambiswa kwemaseketi nekumhanya-mhanya uye akashandiswa zvakanyanya muindasitiri yemauto.
Zvishandiso muAntenna Zvikamu
Nekuti iyo aramid material ine yakanaka dielectric properties, inoiswa muzvikamu zveradome, iyo yakatetepa kupfuura yechinyakare girazi radome, ine kusimba kwakanaka uye yakakwirira chiratidzo chekufambisa.Kuenzaniswa nehafu-wavelength radome, iyo radome iri munzvimbo yepakati inoshandisa aramid zvinhu kugadzira iyo.muzingainterlayer.Iyo yepakati zvinhu yakareruka mukurema uye yakakwirira mukusimba kupfuura yegirazi core material.Izvo zvisingabatsiri ndiyo mari yekugadzira.kumusoro.Nokudaro, inogona kushandiswa chete mukugadzirwa kwezvikamu zveradome muminda yepamusoro-soro yakadai seshibhodhi radar uye radar yemhepo.Makambani eAmerica neJapan vakabatana vakagadzira radar parabolic antenna, vachishandisa zvinhu zvepara-aramid pane radar inotaridza pamusoro.
Kubva patsvakiridzo paaramid fiberzvinhu zvakatanga kunonoka munyika yangu, tekinoroji yakagadzira nekukurumidza.Iyo parizvino yakagadziridzwa setiraiti APSTAR-2R inoshandisa muzinga wehuchi interlayer senzvimbo inotarisisa yeantenna.Matehwe emukati nekunze eantenna anoshandisa para-aramid zvinhu, uye kupindirana kunoshandisa muzinga aramid.Mukugadzirwa kweiyo ndege radome, para-aramid inoshandiswa kutora mukana weiyo yakanaka wave-yekufambisa kuita kwechinhu ichi uye yakaderera yekuwedzera coefficient, saka kuwanda kweiyo reflector inokwanisa kusangana nezvinodiwa zviviri zvechimiro chayo uye basa. .ESA yakagadzira maviri-mavara sub-type reflector ine dhayamita ye1.1m.Inoshandisa meta-huchi chimiro mune sandwich chimiro uye inoshandisa aramid zvinhu seganda.Iyo epoxy resin tembiricha yechimiro ichi inogona kusvika 25°C uye dielectric constant is 3.46.Iyo yekurasikirwa chinhu ndeye 0.013, kurasikirwa kwekutapurirana kwemhando iyi yekuratidzira ingori 0.3dB, uye kurasikirwa kwechiratidzo chekutapurirana ndeye 0.5dB.
Iyo miviri-yemavara sub-type reflector inoshandiswa musetelliti system muSweden ine dhayamita ye1.42m, kurasikirwa kwekutapurirana kwe <0.25dB, uye kurasikirwa kwechiratidzo che <0.1dB.Sangano renyika yangu reElectroniki rakagadzira zvigadzirwa zvakafanana, zvine chimiro chesangweji chakafanana nemaantenna ekunze, asi shandisa aramid zvinhu uye girazi fiber composite zvinhu sematehwe.Kurasika kwekuratidzira kweiyi antenna mune yekutumira link ndeye <0.5dB, uye kurasikirwa kwekutapurirana kuri <0.3 dB.
Zvikumbiro mune mamwe minda
Pamusoro pemashandisirwo ari muminda iri pamusoro, ma aramid faibha anoshandiswawo zvakanyanya muzvinhu zvemagetsi zvakaita semafirimu anoumbwa, tambo dzekudzivirira / tsvimbo, macircuit breaker, uye mabhureki.Semuyenzaniso: Mune 500kV transmission line, shandisa insulating tambo yakagadzirwa nearamid material pane insulating suspender semudziyo unotakura zvinhu, uye shandisa insulating tambo kubatanidza screw rod, iyo inobatsira kukurudzira kuchengetedza chinhu pamusoro pe 3. The insulating tambo tsvimbo inonyanya kuumbwa nearamid faibha uye polyester faibha yakabatana, inoiswa muvacuum, yakanyudzwa mu epoxy resin zvinhu, uye yakaumbwa mushure mekurapa.Iyo ine yakanaka corrosion resistance panguva yekushandiswa, huremu huremu uye simba rakakwirira, uye chinhu ichi chine yakanaka insulation performance.Mumutsara we110kV, kushanda kwekushandisa insulating rods kunowanzoitika, uye simba rayo remagetsi rakakwirira panguva yekushandiswa, uye ine maitiro akanaka ekugadzirisa kuneta.Mukugadzira michina yemagetsi, kushandiswa kwearamid fiber zvinhu zvinogona kuvandudza kusimba kwezvikamu uye kudzivirira kusakara kwakakomba pamusoro pekuumbwa kunotsiva.Inogona kutsiva magirazi egirazi mumidziyo yemagetsi.Fiber content yearamid fibers i5%, uye kureba kunogona kusvika 6.4mm.Iyo tensile simba ndeye 28.5MPa, iyo arc kuramba ndeye 192s, uye simba rekuita i138.68J/m, saka kusamira kwekupfeka kwakakwira.
Zvese muzvese,aramid zvinhuanoshandiswa zvakanyanya mumunda wemagetsi ekudzivirira uye zvemagetsi, asi ivo vari kutarisana nematambudziko.Nyika inofanirwa kuita mapurojekiti akadai sema transformer nemagetsi ekufambisa magetsi kusimudzira kusimudzira nekushandiswa kwemhando iyi yezvinhu mukudzivirira kwemagetsi, uye nekuramba vachidzikisira hunyanzvi hwekushandisa uye zvigadzirwa zvekunze.gap pakati.Panguva imwecheteyo, kushandiswa kwepamusoro-soro mumabhodhi ematunhu, radar nemimwe minda inofanira kukurudzirwa kupa kutamba kwakazara kune zvakanakira kushanda kwezvinhu uye kukurudzira kuvandudzwa kuri nani kwenyika yangu yekudzivirira magetsi uye magetsi emagetsi.
