Ukufafaza kwe-ultrasonic, eyaziwa nangokuthi i-ultrasonic spray, iyinqubo yokufafaza esebenzisa ubuchwepheshe be-atomiwation ye-ultrasonic. Izinto ezizofafazwayo ziqala ngesimo se-liquid. Uketshezi lungaba yisixazululo, i-sol, ukumiswa, njll. Upende we-liquid uqale wahlelwa ngezinhlayiya ezinhle ngokusebenzisa i-Ultrasonic Atomization Prep ngokusebenzisa inani elithile le-Carrier Great. , ngaleyo ndlela kwakheka ukuhlanganiswa noma ifilimu. Umehluko omkhulu phakathi kokufafaza kwe-ultrasonic kanye nendabuko eyodwa - uketshezi noma amabili - ukufafaza uketshezi ukuthi i-atomiting nozzle isebenzisa ithuluzi le-atomiting ye-ultrasonic, okungukuthi, i-nozzle ye-ultrasonic.
Uma kuqhathaniswa nesiko lesibili lendabuko - Ukufafaza kwe-Fluid, ukufafaza kwe-ultrasonic kunezinzuzo zokulingana okuphezulu, ukusetshenziswa okuphezulu okusetshenziswayo, ukuqina okuphezulu kokulawulwa kokuqina, ukuqina okuphezulu, akukho izindleko ze-nozzle, kanye nezindleko zokulungiswa okuphansi. Uma kuqhathaniswa nezinqubo ze-coating ezifana nokuhwamuka kwe-vacuum ne-CVD, isifutho se-ultrasonic siyinqubo yokuhlangana yezomnotho emphakathini. Ikakhulu lapho kulungiswa amafilimu akhudlwana - izindawo ezincanyana zendawo, izindleko zemishini yokufafaza kwe-ultrasonic ziphansi kunalezo zokusebenza ze-vacuum coating.
Izinzuzo eziphambili zokufafaza kwe-ultrasonic yilezi:
1. Ukufana okuphezulu okuphezulu
Ukufana kokusatshalaliswa kwezinhlayiyana okuwuketshezi ngemuva kokufakelwa kwama-nozzles we-ultrasonic kuphakeme kakhulu kunalena amabili - ama-nozzles ajwayelekile, abizwa ngokuthi ukufana kwezibhamu, ngakho-ke ukufana kwenhlamvu ngemuva kokufafaza ama-nozzles kuyathuthukiswa. Imvamisa, ukufana kwe-coating kokufafaza kwe-ultrasonic kungafinyelela ngaphezu kwama-95%.

Njengoba ukufafaza kwe-ultrasonic kungukuhlonza uketshezi ngokusebenzisa i-oscillation ye-ultrasonic, inqubo yokufaka i-paint ayidingi noma yiliphi igesi, okungukuthi, inqubo yokufakelwa kokufakelwa ayidingi ingcindezi. Ingcindezi yegesi ephansi kakhulu ephansi kakhulu esetshenziswayo ngemuva kokufakelwa phansi ukuthutha inkungu ye-liquid. Ngakho-ke, kunciphisa kakhulu i-ketshezi evuselelwayo kanye nokuqhekeka okubangelwa ukuphakama - ukufutheka komoya komoya koketshezi lwesibili, ngaleyo ndlela kuthuthukise kakhulu izinga lokusetshenziswa kopende. Izinga lokusetshenziswa okungavuthiwe kwezinto ezibonakalayo zokufafaza kwe-ultrasonic zingaphezu kwezikhathi ezi-4 zokufafaza komoya okujwayelekile, kanye nezinga lokusetshenziswa kungafinyelela ngaphezulu kwama-90%.
I-3. Ukuqina okuphezulu kokulawula ukunemba
Isici esiyinhloko esithinta ukunemba kokuqina kokuqina kwesilinganiso sokufafaza ukugeleza kwesilinganiso sokugobhoza, okuyinani lezinto ezibonakalayo ezilayishwe endaweni ephansi yesikhathi esithile. I-nozzle ye-ultrasonic ayinawo umphumela wokucindezela ku-ketshezi, ngakho-ke izinga lokugeleza koketshezi lwe-atomided Spray Paist lungalawulwa ngokuphelele yi-High - Ukucaciswa kwe-Metering Pump, ngaleyo ndlela kufinyelele ekuphepheni kokuphenya okuphezulu. Isibonelo, ukunemba kokulawulwa kokugeleza kokuphezulu - Ukuqonda okuyisirinji okuyisirinji kungafinyelela ezingeni lama-picolitres ngomzuzwana, futhi umklamo wesiteshi we-micro - isiteshi
I-4. Ubukhulu be-coating mncane, ufinyelela amashumi ama-nanometers
Njengoba umthamo wokufafaza we-nozzle we-ultrasonic ungafinyelela isilinganiso esisezingeni eliphakeme kakhulu sokugeleza (0.001ml / min), inani elincane kakhulu lokulayisha lingatholwa kwi-substrate, ngaleyo ndlela sifinyelele kwifilimu esomile kakhulu. Kwamanye ama-nanomatadium, ubukhulu befilimu owomile bungaphansi njengamashumi ama-nanometers. Ingasetshenziswa ukulungiselela amafilimu engilazi anjengamafilimu asobala aphaselayo, anti - amafilimu okukhombisa, amafilimu wokufaka insulaction, amafilimu we-hydrophilic kanye ne-hydrophobic.
