Umnyombo osebenzayo we-ultrasonic graphene atomization sprailing imishini isuselwa emthonjeni we-cavitation wamagagasi e-ultrasonic kanye nomgomo wokuphakama komhlaba. Imishini ikakhulukazi yakhiwa nge-generator ye-ultrasonic, i-transducer, i-actifing nozzle kanye ne-spray control system.
Lapho kuqalwa imishini, i-generator ye-ultrasonic yakha okuphezulu - imvamisa kagesi kagesi, edluliselwa ku-transducer. I-transducer imvamisa isebenzisa izinto ze-piezoelectric ceramic ceramic, enesici sokuthi ngemuva kokuthola ukuphakama - imvamisa kagesi, ingaguqula ukudlidliza okunobudlova kube amashumi ezinkulungwane zamashumi ezinkulungwane noma ngaphezulu okuphezulu (20KHZ - 120khz). Lokhu kuphakama - ukudlidliza imvamisa kudluliselwa ku-atomizing nozzle. Lapho i-grapheneli solution igeleza ngokusebenzisa i-nozzle, ngaphansi komphumela onamandla wamagagasi e-ultrasonic, ama-bubble amaningi amancane akhiqizwa ngaphakathi kwesixazululo. Lawa ma-bubble akhiqizwa ngaso leso sikhathi futhi aqhume ngokushesha, akhiqize amandla omthelela aqinile, afake i-grapheling solution amaconsi amahle kakhulu futhi afanayo anobubanzi obunama-microns ambalwa kuphela (aguqukayo phakathi kwe-10 - 45μm).
Ngokungafani nesifutho sengcindezi yendabuko, ethembele phezulu - I-Presung Gas to blow uketshezi kumaconsi, inqubo yokwakheka kwamaconsi yokufafaza kwe-atomization ye-ultrasonic kuthambile futhi iyalawuleka. Lawa ma-micron - amaconsi we-graphene solution afafazwe ebusweni bezinto ezisezingeni eliphakeme ngendlela ezinzile futhi eyunifomu ngaphansi kokuholwa okuphezulu okulungiswe kahle - ijubane lokundiza. Ngemuva kokufinyelela ebusweni be-substrate, amaconsi afakwa ngokulinganayo futhi asakazeka, futhi njengoba i-solvent ivele, ungqimba lwe-graphen coating ngobukhulu bomfaniswano, ukuqina kanye nokunamathela okuqinile kuyakhiwa kancane kancane. Ngokulawulwa okuqondile kwamapharamitha asemqoka anjengemvamisa ye-ultrasonic, amandla okugeleza kwesixazululo kanye nesikhathi sokufafaza, ububanzi be-coation bungalawulwa ngokunembile kuma-nanometer, futhi ahlinzeka ngokuvikelwa okuthembekile ku-± 3 ama-nanometers ngezidingo eziphezulu zokunemba.
Izinkambu zohlelo lokusebenza: Ukunika amandla ama-Innovation and Development kuzimboni eziningi
Inkambu yolwazi nge-elekthronikhi
Ekwenziweni kwamadivayisi we-elekthronikhi aguqukayo, imishini yokufafaza i-atomization ye-ultrasonic graphene atomization idlala indima ebalulekile. Ngokufafaza isixazululo se-graphene ngokulinganayo kwi-flexible polymer substrate, ifilimu elivuthayo elinothando elinokuvuka okuphezulu nokuguquguquka okuhle kungalungiswa. Le filimu isetshenziswa kabanzi kwimikhiqizo efana nokuboniswa okuguquguqukayo kanye namadivayisi we-elekthronikhi agqoke ama-elekthronikhi, okwenza kube nokwenzeka ukufezekisa ukuncipha, ukuguquguquka nokusebenza okuphezulu kwemikhiqizo ye-elekthronikhi. Isibonelo, ekubonisweni okuguquguqukayo kwe-OLED, amafilimu afafazwe e-graphene afafazwe asetshenziswa njenge-electrodes. Uma kuqhathaniswa ne-electrodes yensimbi yendabuko, akunakuthuthukisa kuphela ukudluliselwa kokukhanya kwesikrini futhi kwenze okucashile kwesikrini, kepha futhi kuthuthukise ukuguquguquka kwesikrini futhi kunciphise ubungozi bomonakalo obangelwa ukugoba. Ekukhiqizeni okuhlanganisiwe kwesifunda, ukumbona kwe-graphene kungasetshenziswa ukwenza ngcono ukusebenza kokushisa kokushisa kwama-chip. Ngokufafaza nge-graphene ngaphandle kwe-chip futhi usebenzisa ukuvumelanisa kwayo okuhle kakhulu, ukushisa okukhiqizwe yi-chip kungadilizwa ngokushesha, ukunciphisa ngokuphumelelayo nokushisa kwe-chip kanye nokuphila kwe-chip.
Isitoreji samandla nensimu yokuguqula
Ensimini yamabhethri e-lithium, ukufafaza kwe-ultrasonic kwesixazululo se-graphene ngaphezulu kwezinto zokwakha i-electrode kungakha inethiwekhi esebenza kahle. Lokhu kusiza ekuthuthukiseni kakhulu ukuthuthuka kanye nezinga lokudlulisa le-elektroni le-electrode, ngaleyo ndlela kuthuthukise ukushaja kanye nokuphoqelela ukusebenza kahle kanye nokujikeleza impilo yebhethri le-lithium. Idatha yokuhlola ikhombisa ukuthi ukushaja kanye nokusebenza kahle kwe-lithium yebhethri le-electrodes ephethwe nge-20% - Impilo yebhethri, futhi i-battery cycle yempilo inganwetshwa ngo-30% - iziteshi zamandla okugcina amandla, njll. Emkhakheni wamaseli welanga, ukusebenzisa i-graphene coating ebusweni bamaseli we-Photovoltaic kungathuthukisa ukusebenza kahle kwebhethri lokuvalwa kwebhethri nokukhokhisa ukusebenza kahle, ngaleyo ndlela kuthuthukise ukusebenza kahle kwezithombe zamaseli elanga. Ngasikhathi sinye, ukuqina okuphezulu nokuphikiswa kokugqwala kwe-graphene kungathuthukisa futhi impilo yensizakalo yamaseli welanga ezindaweni zokwangaphandle, kanye nokukhuthaza ukusetshenziswa okusebenzayo kanye nokuthandwa okusabalele kwamandla elanga.
Ukuvikelwa Kwezinto Ezibonakalayo Nensimu Yokuthuthukiswa
Mayelana nokuvikelwa kwezinto ezibonakalayo zensimbi, ngemuva kokuxubana kwe-graphene ne-corrosion - ukumbona okuvimbela izimbotshana, ukufafaza kwe-atomization kwe-ultrasonic endaweni yensimbi kungakha ukuhlanganiswa okuminyene. Lokhu kuhlanganiswa akukwazi ukuhlukanisa insimbi kuphela ekutholeni okuhlobene ne-Complososive Medium, kepha futhi sebenzisa izakhiwo ezinhle kakhulu ze-grapheene ukuthuthukisa amandla okwenziwayo, futhi kuthuthukise kakhulu ukumelana nokugqwala kwezinto ezinolaka ezindaweni ezinokhahlo. Isibonelo, e-Marine Engineering, ukusetshenziswa kwalolu hlelo lwe-graphene yezingxenye zesakhiwo zensimbi ezinjengezingxenyekazi zemikhumbi namapulatifomu okumba olwandle kunganweba kakhulu impilo yabo futhi kunciphise izindleko zokulungiswa kanye nezindleko. Ekulungiseleleni izinto ezihlanganisiwe, i-graphene efafazwe ye-ultrasonic ingahlakazeka ngokulinganayo ezintweni ze-matrix, dlala indima yokuqinisa isigaba, futhi ithuthukise ngempumelelo izakhiwo zemishini zezinto ezihlanganisiwe. Isibonelo, engeza i-graphiene ene-ultrasonically efafazwe ngezinto ezisetshenziswayo ze-carbon fiber composite ezisetshenziselwa insimu ye-aerospace ingathuthukisa amandla nokuqina kwezinto ezibonakalayo, ngenkathi kunciphisa isisindo sezinto ezibonakalayo, ngenkathi kunciphisa isiqinisekiso sezinto ezibonakalayo, ukundiza okuphezulu kwezimoto ze-aerospace.
Inkambu ye-Biomedical
Ensimini ye-biomedical, imishini yokufafaza i-atomization ye-ultrasonic atomization iphinde ikhombise amandla wesicelo esihle. Isibonelo, lapho kulungiswa abathwali bezidakamizwa, isixazululo se-graphene equkethe izidakamizwa sifafazwa ebusweni be-nanoparticles ngokusebenzisa i-atomization ye-ultrasonic ukulungiselela izidakamizwa imisebenzi ethile. Lo mphathi wenethiwekhi angathola ukulethwa okuqondile nokukhishwa kwezidakamizwa okuqhubekayo, athuthukise umphumela wokwelapha wezidakamizwa, futhi anciphise imiphumela emibi yezidakamizwa ezicutshini ezijwayelekile. Ngokuya nge-biosensirs, ngokufafaza i-graphene coating ebusweni bezinzwa, ukuzwela nokukhetha kwenzwa kungenziwa ngcono, futhi ukutholakala okusheshayo nokutholwayo kwama-molekyuli eziphilayo kungatholakala, kunikeze ithuluzi elinamandla lokuxilongwa kwezifo kanye nocwaningo lwe-biomedical.
