Ultrasonic spraying machine for spraying nano silver – Cheersonic

In diverse fields such as electronics manufacturing, biomedicine, textiles, and environmental catalysis, nano-silver, as a novel nanomaterial with a particle size of less than 100nm, has become a key material driving industrial technology upgrades due to its core advantages of low melting point, excellent conductivity, outstanding bactericidal efficacy, and large specific surface area. Nano-silver is mostly spherical particles, but can also be made into special morphologies such as triangles and lines. It has a high number of particles per unit volume and extremely high activity, possessing not only excellent conductivity and optical properties, but also effectively inhibiting and killing dozens of pathogenic microorganisms without drug resistance. It is widely used in the preparation of nano-silver conductive inks, antibacterial dressings, transparent conductive films, and catalytic materials. As a core link in the application of nano-silver, the spraying process directly determines the uniformity, adhesion, and performance of the nano-silver coating. Cheersonic ultrasonic spraying machines, with their core advantages of high precision, low damage, and high adaptability, perfectly meet the needs of nano-silver spraying, providing core equipment support for the mass production and quality improvement of nano-silver products in various fields.

The properties of nano-silver and the application requirements in multiple fields have placed extremely stringent standards on the spraying process, and its performance is deeply tied to the quality of the spraying. Due to the tiny size and high activity of nano-silver particles, it is crucial to avoid issues such as particle agglomeration, uneven coating, and substrate damage during the spraying process. The core spraying requirements focus on three main aspects: First, high uniformity coating requires precise control of the nano-silver coating thickness to adapt to different application scenarios, with a deviation of ≤±0.05μm and uniformity exceeding 98%. Defects such as pinholes and particle agglomeration must be avoided—these defects lead to discontinuous conductive networks and uneven antibacterial properties, preventing the nano-silver from realizing its core advantages. Second, low-damage adaptation is essential. Nano-silver particles are fragile, and the spraying substrates include flexible PET, glass, fabrics, medical dressings, and many other types. Some substrates are not resistant to high pressure and high temperature. The spraying process must be conducted under low pressure and without high temperature throughout to prevent nano-silver particle breakage and substrate damage, while preserving the activity of the nano-silver. Third, high-cleanliness spraying is crucial, especially in the medical and electronics fields. It must meet clean production standards to prevent the introduction of impurities, avoiding any impact on the antibacterial and conductive properties of the nano-silver, while ensuring strong adhesion between the coating and the substrate, preventing it from easily peeling off.

In the current field of nano-silver coating, traditional coating processes (spin coating, air spraying, and dip coating) have many shortcomings, making it difficult to adapt to the characteristics of nano-silver and the application needs of multiple fields, thus becoming a bottleneck restricting its large-scale application. Spin coating has a material utilization rate of less than 40%, wasting a large amount of expensive nano-silver material. High-speed rotation can easily lead to agglomeration of nano-silver particles and excessive coating stress. Moreover, it is only suitable for flat substrates and cannot be adapted to irregular or flexible substrates such as fabrics and flexible electronics. Air spraying relies on high-pressure airflow, which can easily cause nano-silver particle breakage and substrate damage. Uneven droplets can cause pinholes and coating accumulation. At the same time, high-pressure airflow can easily introduce impurities, reducing the cleanliness of the coating. Dip coating is difficult to control the coating thickness precisely, and nano-silver particles are prone to sedimentation, resulting in uneven coating performance. It is only suitable for simple scenarios and cannot meet the high-precision requirements of the electronics and medical fields.

Cheersonic ultrasonic spraying machine addresses the characteristics and spraying challenges of nano-silver by leveraging its core high-frequency atomization technology and incorporating key process points across multiple applications to create customized solutions that completely break through traditional process bottlenecks. The equipment converts industrial frequency electricity into a 40-150kHz high-frequency electrical signal via an ultrasonic generator. This signal is then converted into high-frequency mechanical vibration by a piezoelectric ceramic transducer. Utilizing the ultrasonic cavitation effect, the nano-silver dispersion is atomized into fine droplets of 0.01-3 microns, effectively de-agglomerating nano-silver particle clusters and ensuring uniform dispersion, avoiding agglomeration. This perfectly complements the small particle size and high activity of nano-silver. The atomization process is conducted under low pressure and without high temperature. The droplets are gently deposited on the substrate surface guided only by a slight carrier gas, preventing damage to the nano-silver particles and the substrate. This maximizes the preservation of the conductive and antibacterial activities of the nano-silver while precisely controlling the coating thickness and distribution, laying a solid foundation for subsequent sintering and other processes.

Addressing the core needs of nano-silver spraying, Cheersonic ultrasonic spraying machines demonstrate four key advantages, helping companies across various sectors improve mass production quality and efficiency. First, high uniformity: coating uniformity exceeds 98%, with a deviation of ≤±1%, ensuring uniform distribution of nano-silver particles and guaranteeing consistent conductivity and antibacterial properties, suitable for high-precision applications such as transparent conductive films and antibacterial dressings. Second, low-damage protection: low-pressure, gentle atomization technology avoids damage to nano-silver particles and the substrate, suitable for various substrates including flexible, fabric, and medical materials, balancing coating adhesion and material activity. Third, high material utilization: reaching over 95%, significantly reducing nano-silver material waste and lowering production costs, especially suitable for spraying high-priced nano-silver materials. Fourth, multi-scenario adaptability: supporting automated continuous spraying and cleanroom adaptation, seamlessly integrating into large-scale production lines in electronics, medical, and textile industries, adapting to nano-silver with different morphologies and particle sizes, overcoming the problems of low efficiency, high loss, and poor consistency in traditional processes.

Currently, Cheersonic ultrasonic spraying machines are widely used in nano-silver spraying applications, covering core areas such as nano-silver conductive ink preparation, medical antibacterial dressing coating, transparent conductive film deposition, and textile antibacterial finishing. This helps companies solve problems such as performance degradation and uneven coating caused by traditional spraying processes, achieving breakthroughs in improved nano-silver product coating quality and large-scale mass production. As a leading company in the field of ultrasonic electronic equipment, Cheersonic Ultrasonic has been deeply involved in the nanomaterial spraying field for many years, keeping abreast of nano-silver technology development trends. It can provide customized spraying solutions, covering the entire process from equipment selection and process parameter optimization to nano-silver dispersion adaptation, helping customers fully leverage the core advantages of nano-silver.
