Daim Ntawv Thov Ntawm Ultrasonic Atomization Txau Hauv Kev Npaj Ntawm Nanomaterials?

Ultrasonic atomization spraying (UAS) yog ib lub tshuab uas siv ultrasonic vibration los rhuav cov ntaub ntawv raw rau hauv micron/nanometer- cov tee me me, uas tom qab ntawd thauj mus rau thaj chaw substrate lossis cov tshuaj tiv thaiv los ntawm cov pa roj. Nanomaterials tau npaj los ntawm kev ziab, sintering, lossis tshuaj lom neeg. Nws cov txiaj ntsig tseem ceeb yog nyob rau hauv qhov loj me me me (txog 1-10 μm), meej thiab tswj tau txheej tuab (nm- μm qib), tsis muaj kev puas tsuaj, thiab siv cov khoom siv raw. Nws tau siv dav hauv kev npaj nanofilms, nanopowders, thiab nanocomposite cov ntaub ntawv, thiab tshwj xeeb tshaj yog haum rau high-end teb xws li precision electronics, tshiab zog, thiab biomedicine.

 

1. Nanofilm Fabrication (Feem ntau daim ntawv thov)

Application Scenario:

◆ Semiconductor/Electronic Devices: Conductive nanofilms (xws li, ITO, graphene, carbon nanotube films), insulating films, photoresist coatings;

◆ Lub Zog Tshiab: Lithium{0}}ion roj teeb electrode films (nanosilicon, lithium hlau phosphate coatings), roj cell proton exchange membranes (Nafion film modification), solar cell light absorption layers (quantum dot films);

◆Functional Coatings: Transparent heat-insulating films (nanoTiO₂, ZrO₂ coatings), antibacterial films (nanosilver, zinc oxide coatings), self-tu films (nanoSiO₂ hydrophobic coatings).

Technical Advantages:

◆ Zoo heev Film Uniformity: Uniform droplet size zam txheej txheej tsis xws luag (xws li pinholes thiab tawg) tshwm sim los ntawm "droplet aggregation" nyob rau hauv ib txwm tshuaj tsuag;

◆ Precise thiab Controllable Thickness: Nanoscale rau micrometer- nplai txheej thickness (piv txwv li, 10 nm-5 μm) tuaj yeem ua tiav los ntawm kev kho cov atomization zaus (20-180 kHz), cov kua dej ntws (0.1-10 mL / min), thiab sijhawm txau;

◆ Tsawg-Kev Npaj Kub: Tsawg lub zog kinetic thaum cov tee cuam tshuam rau lub substrate tso cai rau kev npaj ntawm chav tsev kub lossis nruab nrab mus rau qhov kub qis (<200℃), making it suitable for flexible substrates (such as PET, PI films) or thermosensitive materials (such as biomacromolecules, quantum dots).

Tej Case:

◆ Graphene Transparent Conductive Film: Graphene dispersion yog ultrasonically atomized thiab txau rau hauv iav los yog hloov tau yooj yim PET substrate. Tom qab qis- kub kom qhuav, ib zaj duab xis nrog daim ntawv tsis kam<100 Ω/□ and a light transmittance >90% yog tsim, haum rau kov cov ntxaij vab tshaus thiab hloov pauv cov khoom siv;

◆ Lithium- ion roj teeb Silicon-raws li Anode Txheej: Nano- silicon particle dispersion yog sprayed mus rau ib tug tooj liab ntawv ci substrate los ua ib tug uniform silicon -raws li txheej (500 nm-2 μm tuab), kev txhim kho roj teeb muaj peev xwm thiab cycle stability.

2. Kev npaj Nanopowder

Application Scenario:

◆ Hlau / Alloy Nanopowders (piv txwv li, nano-silver, tooj liab, npib tsib xee hmoov): siv rau hauv cov khoom siv pastes, catalysts, thiab 3D luam ntawv raw khoom;

◆Oxide Nanopowders (piv txwv li, TiO₂, ZnO, Al₂O₃ hmoov): siv nyob rau hauv cov ntaub ntawv photocatalytic, ceramic raw khoom, thiab txheej additives;

◆Composite Nanopowders (piv txwv li, Fe₃O₄@SiO₂, quantum dot hmoov): siv rau hauv biosensing, fluorescent probes, thiab cov khoom sib nqus.

Technical Advantages:

◆ Uniform Powder Particle Size: Kev tswj cov tee me me ua rau muaj qhov nqaim particle loj (feem ntau 10-100 nm);

◆ High Purity: Droplets hnov ​​​​mob nyob rau hauv cov roj theem, tsis txhob muab cov impurities raws li nyob rau hauv ib txwm ntub ua;

◆ Controllable Morphology: Los ntawm kev kho cov tshuaj tiv thaiv kub, cov pa roj carbon monoxide ntws, thiab precursor concentration, nanopowders nrog txawv morphologies xws li spherical, flake, thiab pas nrig - zoo li tus hais tuaj yeem npaj tau.

Hom Case:

◆ Kev Npaj Nano-Silver Powder: Silver nitrate tov yog tov nrog ib tug txo tus neeg sawv cev (xws li ethylene glycol), atomized, thiab ces dhau mus rau hauv ib tug 300℃reactor kom txo tau thiab tsim spherical silver hmoov nrog ib tug particle loj ntawm 20-50 nm, siv nyob rau hauv hluav taws xob pastes (xws li volt LED packing).
