Gushyira mu bikorwa ibikoresho bya fibre ya Aramide mumashanyarazi no mumashanyarazi (2)

Porogaramu mu icapiro ryumuzingo

Mubikorwa byo gukora imbaho ​​zicapye zicapuwe (aha bita PCB), fibre yamid ikoreshwa muguhuza ibyuma byinshi bya elegitoroniki ya chip.Ubu bwoko bwinkunga bufite ibintu bikomeye, birashobora rero kwirinda impapuro z'umuringa hamwe na resin substrate nyuma yo gushyuha.ibibazo byo gutandukana.Mu nganda za elegitoroniki, gukoresha ibikoresho bya aramid mugukora imbaho ​​za PCB birashobora kongera imbaraga nubwiza bwibibaho.Ubu bwoko bwumuzunguruko bufite ubunini bwiza hamwe na coefficient yo kwaguka ya 3×10-6 /℃.Bitewe na dielectric nkeya ihoraho yumuzunguruko, irakwiriye kwihuta kwihuta kumirongo.

Ugereranije nibikoresho bya fibre fibre, ubwinshi bwiki kibaho cyumuzunguruko bugabanukaho 20%, bityo ukamenya intego yo gukora uburemere bworoshye na sisitemu ntoya yibikoresho bya elegitoroniki.Isosiyete y'Abayapani yateje imbere ikibaho cya PCB gifite umutekano muke, guhinduka cyane, no kurwanya ubushuhe bukomeye.Mubikorwa byo gukora,aramid fibrezikoreshwa muri meta-imyanya, yihutisha gutegura ibikoresho bya epoxy ishingiye kubikoresho.Ugereranije no gukoresha ibikoresho bitandukanye, biroroshye gutunganya kandi bifite imikorere myiza yo kwinjiza neza.PCBs ikozwe muri fibre ya aramid yoroheje muburemere kandi ikomeye mubikorwa, kandi irashobora gukoreshwa muri terefone zigendanwa na mudasobwa ya tablet.Byongeye kandi, imbaho ​​zumuzunguruko zigezweho zishingiye kuri fibre ya aramid ifite imiterere-karemano irashobora gupakira ibikoresho bya elegitoroniki yuzuye cyane, bikwiranye nogukwirakwiza umuvuduko mwinshi kandi byakoreshejwe cyane mubikorwa bya gisirikare.

Porogaramu muri Antenna Ibigize

Kuberako ibikoresho bya aramide bifite imiterere ya dielectric, ikoreshwa mubice bya radome, bikaba byoroshye kuruta ibirahuri gakondo byikirahure, hamwe no gukomera no kohereza ibimenyetso byinshi.Ugereranije na kimwe cya kabiri cyumurambararo wa radome, radome mumwanya uhuza ikoresha ibikoresho bya aramid kugirango ikoreubukiinterlayer.Ibikoresho byibanze byoroheje muburemere kandi birenze imbaraga kuruta ibirahuri by'ibirahure.Ingaruka ni ikiguzi cyo gukora.hejuru.Kubwibyo, irashobora gukoreshwa gusa mugukora ibice bya radome mumirima yohejuru nka radar yubwato na radar yo mu kirere.Amasosiyete y'Abanyamerika n'Ubuyapani bafatanije gukora antenne ya radar parabolike, bakoresheje ibikoresho bya para-aramid hejuru yerekana radar.

Kuva ubushakashatsi kuriaramid fibreibikoresho byatangiye bitinze mugihugu cyanjye, ikoranabuhanga ryateye imbere byihuse.Kugeza ubu icyogajuru APSTAR-2R yateje imbere ikoresha ubuki hagati yubuki bugaragara nka antene.Uruhu rwimbere ninyuma rwa antenne rukoresha ibikoresho bya para-aramid, naho intera ikoresha ubuki bwikimamara.Mubikorwa byo gukora indege radome, para-aramid ikoreshwa mugukoresha inyungu nziza yohereza imiyoboro yibi bikoresho hamwe na coefficente yo kwaguka, bityo inshuro ya ecran irashobora kuba yujuje ibyangombwa bibiri byimiterere n'imikorere yayo. .ESA yakoze ibara ryibara ryibara ryibiri rifite diameter ya 1,1m.Ikoresha meta-ubuki muburyo bwa sandwich kandi ikoresha ibikoresho bya aramid nkuruhu.Epoxy resin ubushyuhe bwiyi miterere irashobora kugera kuri 25°C hamwe na dielectric ihoraho ni 3.46.Igihombo ni 0.013, igihombo cyo kugaragariza ihuriro ryikwirakwizwa ryubwoko nkubu ni 0.3dB gusa, naho gutakaza ibimenyetso byoherejwe ni 0.5dB.

Ibara ryibara ryibara ryibiri ryakoreshejwe muri sisitemu ya satelite muri Suwede rifite umurambararo wa 1,42m, igihombo cyoherejwe na <0.25dB, hamwe no gutakaza <0.1dB.Ikigo cyigihugu cya Electronics cyateje imbere ibicuruzwa bisa, bifite imiterere ya sandwich imwe na antenne zamahanga, ariko ikoresha ibikoresho bya aramid hamwe nibikoresho bya fibre fibre yibigize uruhu.Igihombo cyo kwerekana iyi antenne muguhuza ni <0.5dB, naho igihombo cyohereza ni <0.3 dB.

Porogaramu mu zindi nzego

Usibye porogaramu ziri mumirima yavuzwe haruguru, fibre ya aramid nayo ikoreshwa cyane mubice bya elegitoronike nka firime ikomatanya, imigozi ikingira imigozi / inkoni, imashini zangiza, na feri.Kurugero: Mumurongo wa 500kV wohereza, koresha umugozi wogukora wakozwe mubikoresho bya aramide aho kugirango uhagarike guhagarikwa nkigikoresho cyikoreza imitwaro, kandi ukoreshe umugozi wikingira kugirango uhuze inkoni ya screw, ifasha mukuzamura ibintu byumutekano hejuru 3. Gukingira inkoni igizwe ahanini na fibre ya aramid na polyester fibre ifatanye, igashyirwa mu cyuho, ikinjizwa mu bikoresho bya epoxy resin, hanyuma ikorwa nyuma yo gukira.Ifite ruswa irwanya ruswa mugihe ikoreshwa, uburemere bworoshye nimbaraga zisumba izindi, kandi ibi bikoresho bifite imikorere myiza yo kubika.Mu murongo wa 110kV, imikorere yo gukoresha inkoni irinda ni inshuro nyinshi, kandi imbaraga zayo zikoreshwa ni nyinshi mugihe cyo kuyikoresha, kandi ifite imiterere myiza yo kurwanya umunaniro.Mu gukora imashini zikoresha amashanyarazi, gukoresha ibikoresho bya fibre ya aramide birashobora kongera imbaraga zibigize kandi bikarinda kwambara cyane hejuru yabasimbuye.Irashobora gusimbuza fibre yibirahuri mubikoresho byamashanyarazi.Fibre yibikoresho bya aramid ni 5%, kandi uburebure bushobora kugera kuri 6.4mm.Imbaraga zingana ni 28.5MPa, kurwanya arc ni 192, naho imbaraga zingaruka ni 138.68J / m, bityo kwihanganira kwambara bikaba hejuru.

Byose muri byose,ibikoresho bya aramidzikoreshwa cyane mubijyanye no gukwirakwiza amashanyarazi na elegitoroniki, ariko kandi zihura ningorane.Igihugu kigomba gukora imishinga nka transformateur n’ibikoresho byohereza amashanyarazi hagamijwe guteza imbere no gukoresha ubu bwoko bwibikoresho mu gukumira amashanyarazi, kandi bikagabanya guhora bikoresha tekiniki n’ibicuruzwa byo hanze.icyuho hagati.Muri icyo gihe, porogaramu zinoze cyane mu mbaho ​​z’umuzunguruko, radar no mu zindi nzego zigomba gushishikarizwa gukina neza ibyiza byo gukora ibintu no guteza imbere iterambere ry’iterambere ry’amashanyarazi mu gihugu cyanjye ndetse n’ikoranabuhanga rya elegitoroniki.
