Ama-nanopowder amahlanu—izinto ezivamile zokuvikela i-electromagnetic

Njengamanje, okusetshenziswa kakhulu okuyinhlanganisela yokuvikela i-electromagnetic shielding, ukwakheka kwayo ikakhulukazi i-resin eyenza ifilimu, i-conductive filler, i-diluent, i-ejenti yokuhlanganisa nezinye izithasiselo.Phakathi kwabo, i-conductive filler iyingxenye ebalulekile.Impushana yesiliva ne-copper powder, i-nickel powder, i-powder yethusi ehlanganiswe ngesiliva, i-carbon nanotubes, i-graphene, i-nano ATO nokunye okuvame ukusetshenziswa.

1.I-Carbon nanotube

Ama-nanotubes e-carbon ane-aspect ratio enkulu kanye nezakhiwo ezinhle zikagesi nezikazibuthe, futhi abonisa ukusebenza okuhle kakhulu ekuvikelweni kukagesi nokumunca.Ngakho-ke, ukubaluleka okwandayo kunamathiselwe ocwaningweni nasekuthuthukisweni kwama-filler conductive njengama-electromagnetic shielding coatings.Lokhu kunezidingo eziphezulu zokuhlanzeka, ukukhiqiza kanye nezindleko ze-carbon nanotubes.Ama-carbon nanotubes akhiqizwe yi-Hongwu Nano Factory, okuhlanganisa nama-CNT anodonga olulodwa futhi anezindonga eziningi, anobumsulwa obufika ku-99%.Ukuhlakazwa kwe-carbon nanotubes ku-resin ye-matrix nokuthi inobungane obuhle ne-matrix resin iba yisici esiqondile esithinta ukusebenza kokuvikela.I-Hongwu Nano iphinde inikeze isisombululo sokuhlakazwa kwe-carbon nanotube ehlakazekile.

2. I-Low Bulk Density kanye ne-SSA ephansii-flake silver powder

Izingubo zokugqoka zokuqala ezitholakala esidlangalaleni zazinelungelo lobunikazi e-United States ngo-1948 ukwenza izinto ezinamathelayo ezenziwe ngesiliva ne-epoxy.Upende ovikela i-electromagnetic shielding olungiswe yimpushana yesiliva egaywe ngebhola ekhiqizwa yi-Hongwu Nano unezici zokumelana nogesi omncane, ukuhamba kahle kukagesi, ukusebenza kahle kokuvikela, ukumelana nemvelo okuqinile kanye nokwakhiwa okulula.Isetshenziswa kabanzi kwezokuxhumana, i-electronics, yezokwelapha, i-aerospace, izikhungo zenuzi kanye neminye imikhakha yopende wokuvikela ibuye ifanele i-ABS, i-PC, i-ABS-PCPS kanye nezinye izimbobo zepulasitiki zobunjiniyela.Izinkomba zokusebenza zifaka ukumelana nokugqoka, ukumelana nokushisa okuphezulu nokuphansi, ukumelana nokushisa nomswakama, ukunamathela, ukumelana nogesi, nokuhambisana kwe-electromagnetic.

3. Impushana yethusifuthii-nickel powder

I-Copper powder conductive coatings inezindleko eziphansi, kulula ukuyisebenzisa, inomphumela omuhle wokuvikela i-electromagnetic, futhi isetshenziswa kabanzi.Afaneleka ngokukhethekile ukuphazanyiswa kwamagagasi kagesi emikhiqizweni ye-elekthronikhi enamapulasitiki obunjiniyela njengegobolondo, ngoba upende we-copper powder conductive ungafuthwa kalula noma ubhulashwe emimoyeni ehlukahlukene yepulasitiki esetshenziselwa ukwenza indawo engaphezulu, futhi indawo yepulasitiki yenziwe ngensimbi ukwenza i-electromagnetic shielding conductive layer, ukuze ipulasitiki ifinyelele inhloso yokuvikela amagagasi kagesi.Ukuma kanye nenani le-powder yethusi kunethonya elikhulu ekuqhubeni kokugqoka.Impushana yethusi inomumo oyindilinga, umumo we-dendritic, umumo weshidi nokunye okunjalo.Ishidi likhulu kakhulu kunendawo yokuxhumana eyindilinga futhi libonisa ukuqhutshwa okungcono.Ngaphezu kwalokho, i-powder yethusi (impushana yethusi ehlanganiswe nesiliva) ihlanganiswe ne-powder yesiliva yensimbi engasebenzi, okungelula ukuthi ifakwe i-oxidized.Ngokuvamile, okuqukethwe kwesiliva ku-5-30%.I-Copper powder conductive coating isetshenziselwa ukuxazulula ukuvikelwa kwe-electromagnetic of engineering plastics kanye nezinkuni ezifana ne-ABS, i-PPO, i-PS, njll. Futhi izinkinga zokuqhuba, zinezinhlobonhlobo zezinhlelo zokusebenza kanye nenani lokuphromotha.

Ngaphezu kwalokho, imiphumela yokulinganisa ukusebenza kahle kokuvikela kuka-electromagnetic yezingubo zokuvikela ugesi ezixutshwe ne-nano-nickel powder kanye ne-nano-nickel powder kanye ne-micro-nickel powder zibonisa ukuthi ukungezwa kwe-nano-nickel powder kunganciphisa ukusebenza kahle kokuvikela ugesi, kodwa kungakhuphula izinga lokushisa. ukulahlekelwa ukumuncwa ngenxa yokwanda.I-tangent yokulahlekelwa kazibuthe inciphisa umonakalo odalwe amagagasi kagesi endaweni ezungezile namathuluzi kanye nokulimala empilweni yomuntu.

4. NanoI-ATOI-Tin oxide

Njengokugcwalisa okuyingqayizivele, i-nano-ATO powder inokucaca okuphezulu kanye nokusebenza kahle, futhi inezinhlelo zokusebenza ezibanzi ekuboniseni izinto zokumboza, i-conductive antistatic coatings, i-transparent thermal insulation coatings neminye imikhakha.Phakathi kwezinto zokumboza zedivayisi ye-optoelectronic, izinto ze-ATO zine-anti-static, anti-glare kanye nemisebenzi elwa nemisebe, futhi zaqala ukusetshenziswa njengezinto zokumboza zokuvikela ugesi ukuze ziboniswe.Izinto zokumboza ze-Nano ATO zinokucaca okuhle kombala wokukhanya, ukuhamba kahle kukagesi, amandla emishini nokuzinza.Kungenye yezicelo ezibaluleke kakhulu zezimboni zezinto ze-ATO kumishini yokubonisa.Amadivayisi we-Electrochromic, njengezibonisi noma amawindi ahlakaniphile, ayisici esibalulekile sezinhlelo zokusebenza zamanje ze-nano ATO kunkambu yokubonisa.

5. I-graphene

Njengento entsha yekhabhoni, igraphene kungenzeka ibe isivikelo sogesi esisha esisebenzayo noma into emunca i-microwave kunama-carbon nanotubes.Izizathu eziyinhloko zihlanganisa lezi ezilandelayo:

Ukuthuthukiswa kokusebenza kokuvikela kazibuthe kanye nezinto ezimuncayo kuncike kokuqukethwe yi-ejenti emuncayo, izici ze-ejenti emuncayo kanye nokumatanisa okuhle kwe-impedance ye-substrate emuncayo.I-graphene ayigcini nje ngokuba nesakhiwo somzimba esiyingqayizivele kanye nezakhiwo ezinhle kakhulu zemishini ne-electromagnetic, kodwa futhi inezindawo ezinhle zokumunca ama-microwave.Uma kuhlanganiswe ne-nanoparticles kazibuthe, kungatholakala into entsha emuncayo, enokulahlekelwa nguzibuthe nokulahlekelwa kukagesi.Inethuba elihle lokufaka isicelo emkhakheni wokuvikela i-electromagnetic kanye nokumuncwa kwe-microwave.
