Izicelo kumabhodi esekethe aphrintiwe
Enqubweni yokukhiqiza amabhodi esekethe aphrintiwe (okuzobizwa ngawo manje ngokuthi i-PCB), amafayibha e-aramid asetshenziselwa ukuhlanganisa izisekelo ze-chip lead ze-electronic.Lolu hlobo lokusekela lunezakhiwo eziqinile eziqinile, ngakho-ke lungagwema amashidi ethusi kanye nama-resin substrates ngemva kokushiswa.izinkinga zokuhlukana.Embonini ye-electronics, ukusetshenziswa kwezinto ze-aramid ukwenza amabhodi e-PCB kungathuthukisa amandla kanye nekhwalithi yamabhodi wesifunda.Lolu hlobo lwebhodi lesifunda lunosayizi omuhle kanye ne-coefficient yokunweba engu-3×10-6/℃.Ngenxa ye-dielectric engaguquki ephansi yebhodi lesifunda, ifanele ukudluliswa kwemigqa ngesivinini esikhulu.
Uma kuqhathaniswa nezinto zokwakha ze-glass fiber, ubukhulu baleli bhodi lesifunda liyancipha ngo-20%, ngaleyo ndlela liqaphela umgomo wokukhiqiza wesisindo esilula kanye nesistimu encane yemishini kagesi.Inkampani yaseJapan ithuthukise ibhodi le-PCB elinozinzo olungcono, elivumelana nezimo eziphakeme, kanye nokumelana nomswakama okuqinile.Enqubweni yokukhiqiza,imicu ye-aramidezisetshenziswa ku-meta-position, esheshisa ukulungiswa kwezinto ezisekelwe epoxy-based resin.Uma kuqhathaniswa nokusetshenziswa kwezinto eziphambene, kulula ukusetshenzwa futhi kunokusebenza okungcono kokumunca umswakama.Ama-PCB enziwe ngamafayibha e-aramid anesisindo esilula futhi aqinile ekusebenzeni, futhi angasetshenziswa kuma-smartphones namathebulethi amakhompyutha.Ngaphezu kwalokho, amabhodi esekethe amanje asekelwe ku-aramid fiber anesakhiwo esinezingqimba eziningi angapakisha ama-elekthronikhi aphezulu kakhulu, afanele ukudluliswa kwamasekethe ngesivinini esikhulu futhi asetshenziswe kabanzi embonini yezempi.
Izicelo ku-Antenna Components
Ngenxa yokuthi impahla ye-aramid inezinto ezinhle ze-dielectric, isetshenziswa ezingxenyeni ze-radome, ezacile kune-radome yengilazi evamile, enokuqina okuhle kanye nokudluliswa kwesignali ephakeme.Uma kuqhathaniswa ne-radome yohhafu-wavelength, i-radome endaweni ye-interlayer isebenzisa impahla ye-aramid ukwenzaikhekheba lezinyosiinterlayer.I-core material ilula ngesisindo futhi inamandla amakhulu kune-glass core material.Ububi yizindleko zokukhiqiza.ngaphezulu.Ngakho-ke, ingasetshenziswa kuphela ekwenzeni izingxenye ze-radome ezindaweni eziphezulu ezifana ne-shipboard radar kanye ne-airborne radar.Izinkampani zaseMelika kanye neJapan ngokuhlanganyela bakha i-radar parabolic antenna, besebenzisa izinto ze-para-aramid endaweni ekhanyayo ye-radar.
Kusukela ucwaningo oni-aramid fiberizinto zokwakha zaqala sekwephuzile ezweni lami, ubuchwepheshe buthuthuke ngokushesha.Isathelayithi ethuthukisiwe i-APSTAR-2R isebenzisa i-interlayer yekhekheba lezinyosi njengendawo ekhanyayo ye-antenna.Izikhumba zangaphakathi nezingaphandle ze-antenna zisebenzisa izinto ze-para-aramid, kanti ukuhlangana kusebenzisa i-aramid yekhekheba lezinyosi.Enqubweni yokukhiqiza i-radome yendiza, i-para-aramid isetshenziselwa ukusizakala ngokusebenza okuhle kokudlulisa amagagasi kwalesi sisetshenziswa kanye ne-coefficient ephansi yokwandisa, ukuze imvamisa yesibonisi sikwazi ukuhlangabezana nezidingo ezimbili zesakhiwo nomsebenzi waso. .I-ESA ithuthukise isibonisi esinemibala emibili esinobubanzi obungu-1.1m.Isebenzisa isakhiwo se-meta-honeycomb esakhiweni sesemishi futhi isebenzisa impahla ye-aramid njengesikhumba.Izinga lokushisa le-epoxy resin yalesi sakhiwo lingafinyelela ku-25°C kanye ne-dielectric constant ingu-3.46.Isici sokulahlekelwa ngu-0.013, ukulahlekelwa kokubonisa kwesixhumanisi sokudlulisela salolu hlobo lwesibonisi yi-0.3dB kuphela, futhi ukulahlekelwa kwesignali yokudlulisela kungu-0.5dB.
Isibonisi esimibalabala esingaphansi kwezinhlobo ezimbili esisetshenziswa ohlelweni lwesathelayithi e-Sweden sinobubanzi obungu-1.42m, ukulahleka kokudlulisela okungu-<0.25dB, kanye nokulahlekelwa kokubonisa okungu-<0.1dB.I-Institute of Electronics yezwe lami ithuthukise imikhiqizo efanayo, enesakhiwo sesemishi elifanayo nezimpondo zakwamanye amazwe, kodwa isebenzisa izinto ze-aramid kanye nezinto ezihlanganisiwe ze-glass fiber njengezikhumba.Ukulahlekelwa kokuboniswa kwale antenna kusixhumanisi sokudlulisela kungu-<0.5dB, futhi ukulahlekelwa kokudlulisela kungu-<0.3 dB.
Izinhlelo zokusebenza kwezinye izinkambu
Ngaphezu kokusetshenziswa kule mikhakha engenhla, ama-aramid fibers nawo asetshenziswa kakhulu ezintweni zikagesi ezifana namafilimu ayinhlanganisela, izintambo/izinduku ezivikelayo, ama-circuit breaker, namabhuleki.Isibonelo: Kulayini kagesi ongu-500kV, sebenzisa intambo evikelayo eyenziwe ngezinto ze-aramid esikhundleni sokuvala isilengalenga njengethuluzi elithwala umthwalo, futhi usebenzise intambo evikelayo ukuxhuma i-screw rod, esiza ekukhuthazeni isici sokuphepha esingaphezulu kuka-3. i-rod yakhiwa ikakhulukazi i-aramid fibre kanye ne-polyester fiber ehlanganisiwe, ifakwe endaweni engenalutho, icwiliswe ku-epoxy resin material, futhi yakhiwe ngemva kokwelashwa.Inokumelana nokugqwala okuhle ngesikhathi sokusetshenziswa, isisindo esilula namandla aphezulu, futhi le nto inokusebenza okuhle kokufakwa.Elayini we-110kV, ukusebenza kokusebenzisa ama-insulating rods kuvame ukuqhathaniswa, futhi amandla ayo omshini aphakeme ngesikhathi sokufaka, futhi unezici ezinhle zokumelana nokukhathala.Ekwenziweni kwemishini kagesi, ukusetshenziswa kwezinto ze-aramid fibre kungathuthukisa amandla ezingxenye futhi kuvimbele ukuguga okungathí sina ebusweni bokushintshwa kokubumba.Ingashintsha imicu yengilazi emishinini kagesi.Okuqukethwe kwe-fiber emicu ye-aramid ku-5%, kanti ubude bungafinyelela ku-6.4mm.Amandla aqinile angama-28.5MPa, ukumelana kwe-arc kungu-192s, futhi amandla omthelela angu-138.68J/m, ngakho ukumelana nokugqoka kuphezulu.
Sekukonke,izinto ze-aramidasetshenziswa kabanzi emkhakheni wokufakelwa ugesi kanye ne-electronics, kodwa futhi abhekene nobunzima.Izwe kufanele lenze amaphrojekthi afana nama-transformer kanye nemishini yokudlulisa amandla ukukhuthaza ukukhuthazwa kanye nokusetshenziswa kwalolu hlobo lwezinto ezibonakalayo ekufakeni ugesi, futhi kunciphise ngokuqhubekayo izinhlelo zokusebenza zobuchwepheshe kanye nemikhiqizo yangaphandle.igebe phakathi.Ngesikhathi esifanayo, izinhlelo zokusebenza ezisebenza kahle kakhulu kumabhodi wesifunda, i-radar nezinye izinkambu kufanele zikhuthazwe ukunikeza umdlalo ogcwele izinzuzo zokusebenza kwezinto ezibonakalayo futhi zikhuthaze ukuthuthukiswa okungcono kokufakwa kukagesi kwezwe lami kanye nezinkambu ze-electronics.
