EHD industrial grade electrohydrodynamic spray film equipment, through the high pressure electric field guide high-speed jet tip to break the Rayleigh limit, burst several times to produce fL droplets, Can be deposited >50nm thick uniform dense film. Compared with 2D film spinning and scraping, can prepared 3D and hollow structure micro and nano films, used in microelectronics, semiconductors, energy batteries, biomedicine and other special equipment. We can also provide customers with special customized printing systems, mass production equipment and whole process supporting services according to specific project requirements.
Unique software algorithm, can design spraying path, accurately control spraying process.
Higher precision positioning vision, shooting spraying process and details, real-time online observation system.
Support standard CNC G code, equipment programming is convenient, convenient to achieve functions.
Applicable material system: photoresist, perovskite, nanomaterials, polymer monomers and other organic/inorganic inks.
Can integrate multi-nozzle, customized.
Minimum spray film thickness: ＞50nm.
Suitable for wide viscosity of materials.
30-50% less than conventional air nozzles.
| Technology | Air spray | Ultrasonic spray | Electrohydrodynamic spray |
Micromorphology |  |  |  |
| Advantage | -High capacity (High flow / 20 ml/min) | -Droplet size : 10~25μm | -Droplet size： 200nm~5μm. - Optimum uniformity. - Viscosity: Highest10000cPs. - High capacity (High flow rate20ml/min） - Save the amount of liquid medicine: low reflectivity of liquid. - Coating transfer rate: over 95%. - Suitable for most functional materials. - Electric field effect. |
| Disadvantage | - Droplet Size : 10~100μm - Viscosity : ~50cPs - Coating transfer rate：25%~35% -Stains due to unevenness. | - Low capacity (Low traffic/Maximum 100μl/min) -Viscosity : ~100cPs |
