Shanghai Yangmi's ultrasonic spraying equipment boasts a raw material utilization rate of over 90% (far exceeding the 30%-50% of traditional air spraying), significantly reducing zinc oxide solution loss and making it particularly suitable for high-value nano zinc oxide dispersions. Furthermore, ultrasonic spraying technology offers excellent process controllability, allowing for precise control of coating thickness (from tens of nanometers to tens of micrometers) and microstructure by adjusting parameters such as ultrasonic power, nozzle movement speed, and solution concentration.
1. Zinc Oxide Coatings and Coatings
As an additive for anti-corrosion and anti-mildew coatings: Zinc oxide solution can combine with resins in coatings to form a dense protective film, used in metal anti-corrosion coatings (such as ship and steel structure coatings) and wall anti-mildew coatings, improving the durability and antibacterial properties of the coating.
Functional Coatings: Adding zinc oxide solution to building exterior wall coatings utilizes its photocatalytic properties (decomposing organic matter under ultraviolet irradiation) to achieve a "self-cleaning" effect, reducing dust adhesion to walls.
2. Electronics and Semiconductor Fields
Transparent Conductive Films: Zinc oxide solution can be prepared into transparent conductive films using ultrasonic spraying processes, used in touchscreens, liquid crystal displays (LCDs), and electrode layers of solar cells. Compared to traditional ITO (indium tin oxide), zinc oxide raw materials are lower in cost and more environmentally friendly.
Semiconductor Devices: As a semiconductor material, zinc oxide solution is used to fabricate epitaxial layers for varistors, thin-film transistors (TFTs), and light-emitting diodes (LEDs), suitable for the miniaturization and high-performance requirements of electronic components.
3. Antibacterial and Medical Fields
Medical Dressings: Zinc oxide solution is coated onto gauze and non-woven fabrics to create antibacterial dressings, which can be used for wound healing (such as burns and ulcers). Its antibacterial properties inhibit bacterial growth while keeping the wound moist.
4. Textile and Dyeing Fields
Functional Textiles: Zinc oxide solution is coated onto fabric surfaces using ultrasonic spraying technology, giving the fabric antibacterial and UV-resistant properties. This is used in sun-protective clothing, antibacterial underwear, and medical protective clothing.
5. Energy Fields
Lithium-ion Battery Electrode Materials: Zinc oxide solution can be used to prepare negative electrode materials for lithium-ion batteries (such as zinc oxide/carbon composites), improving electrode conductivity and cycle stability.
Photocatalytic Hydrogen Production: Utilizing the photocatalytic properties of zinc oxide, its solution is coated onto a carrier to decompose water to produce hydrogen under light, representing a clean energy research direction.
Ultrasonic spraying technology meets the customized needs of different scenarios such as electronic transparent conductive films and new energy battery electrodes. Moreover, the equipment operates with low noise and without high-pressure airflow disturbance, making it more suitable for refined and large-scale industrial production.
