1. Preparation of nanomaterials: precise control of particle size distribution
Application fields:
Metal nanoparticles: Preparation of silver, gold, copper and other nanoparticles (particle size<100nm) for use in conductive inks and catalysts.
Oxide nano materials: synthesis of TiO ₂, ZnO and other nano powders (specific surface area>50m ²/g) to improve photocatalytic performance.
Carbon materials: Disperse graphene and carbon nanotubes (CNT) to prevent agglomeration and improve the conductivity of composite materials.
Technical advantages:
Compared to traditional ball milling methods, the particle size distribution is narrower (PDI<0.2), reducing subsequent screening steps.
The cavitation effect can strip layered materials (such as graphene), increasing the monolayer rate to over 90%.
2. Biopharmaceuticals: Cell lysis and drug delivery
Application fields:
Cell fragmentation: Extracting enzymes and proteins from bacterial/yeast cells (fragmentation rate>95%), with an efficiency 2-3 times that of high-pressure homogenizers.
Liposome preparation: Form uniform liposomes (particle size 50-200nm) to encapsulate drugs (such as anticancer drug paclitaxel) and improve targeting.
Vaccine production: Breaking down virus particles releases antigens (such as influenza virus HA protein) while retaining immunogenicity.
Technical advantages:
Low temperature operation (can be equipped with a cooling system) to avoid denaturation of thermosensitive biomolecules (such as proteins).
The cavitation effect can penetrate the cell wall, and the fragmentation efficiency is 50% higher than that of chemical lysis.
3. Food industry: improving texture and stability
Application fields:
Dairy products: prepare stable oil in water lotion (such as cream and ice cream) to prevent fat from floating (shelf life is extended by 30%).
Beverages: Disperse dietary fiber (such as inulin), pigments (such as beta carotene), and increase solubility (solubility increases 2-5 times).
Seasoning: Homogenize chili oil and Sichuan pepper oil to form uniform droplets (particle size<5 μ m), enhancing flavor release efficiency.
Technical advantages:
Replacing traditional high-pressure homogenizers, energy consumption is reduced by 40%, and there is no risk of metal contamination.
The cavitation effect can destroy the structure of starch granules and reduce viscosity (such as a 20% decrease in gelatinization degree of corn starch).
4. Coatings and inks: improving dispersion stability
Application fields:
Water based coating: Disperse pigments such as titanium dioxide and calcium carbonate (particle size D50<1 μ m) to prevent settling (no hard settling after 6 months).
UV ink: disperses photoinitiators and monomers to form a transparent system (light transmittance>90%), improving curing speed.
Conductive ink: Disperse silver powder and graphene to prepare low resistance (<10m Ω/sq) flexible circuits.
Technical advantages:
Compared to sand mills, the dispersion time is reduced to 1/5 and there is no medium wear and pollution.
The cavitation effect can activate the surface active groups of pigments, improving compatibility with resins (adhesion increased by 30%).
5. New energy materials: optimizing battery performance
Application fields:
Lithium ion batteries: dispersing positive electrode materials (such as NCM, LFP) and conductive agents (such as carbon black) to improve electrode conductivity (reducing internal resistance by 15%).
Fuel cell: Prepare platinum catalyst support (such as carbon nanotubes), disperse platinum particles (particle size 2-5nm), and enhance catalytic activity.
Supercapacitors: Disperse activated carbon and graphene to form high specific surface area electrodes (specific capacitance>300F/g).
Technical advantages:
The cavitation effect can remove the surface oxide layer of materials, exposing more active sites (increasing catalytic activity by 20%).
Low temperature operation avoids electrode deformation and is suitable for continuous production of roll to roll (R2R).
6. Environmental governance: efficient degradation of pollutants
Application fields:
Wastewater treatment: Degradation of organic pollutants (such as dyes and pesticides), COD removal rate>90%, and reaction time reduced to 1/10 of traditional methods.
Sludge treatment: Crushing microbial cells, releasing organic matter (such as proteins and fats), and improving anaerobic digestion efficiency (increasing gas production by 25%).
Soil remediation: Disperse heavy metal ions (such as Pb ² ⁺, Cd ² ⁺) for subsequent leaching or plant extraction.
Technical advantages:
The cavitation effect generates hydroxyl radicals (· OH), which have an oxidation ability 1.35 times that of ozone.
Can be used in combination with Fenton reagent to reduce H ₂ O ₂ usage by 30% and decrease sludge production.
