In the field of atomization technology, the diameter of atomized particles of Atomizer Plate directly determines the application effect, especially the two common specifications of 1 micron and 5 micron, which show significant differences in medical and consumer electronics scenarios. Shenzhen Liandaqi Precision Ceramic Co., Ltd., as a core R&D enterprise of Ceramic Atomizer Plate and Piezoceramic Transducer, has deeply analyzed the effect differences between the two particle sizes through technical measurement and scene verification, providing professional reference for the selection of different industries.
From the core performance point of view, the 1-micron particle size Atomizer Plate relies on high-precision Piezoceramic Transducer drive, with a vibration frequency of up to 120kHz, which can crush liquid into finer fog droplets. The advantage of this type of atomizing sheet is that the droplets have strong penetration and uniform diffusion, and the droplets can be suspended in the air for a long time. In medical scenarios, Liandaqi's Nasal Spray Atomizer Atomizer Plate adopts a 1-micron particle size design. The drug droplets can accurately penetrate the nasal mucosa and reach respiratory lesions. The absorption efficiency is more than 40% higher than the 5-micron particle size, especially suitable for local drug administration for diseases such as asthma and rhinitis.

The Ceramic Atomizer Plate with a particle size of 5 microns has a vibration frequency of 80-100kHz. Although the atomized particles are slightly larger, the atomization amount is higher (usually 30%-50% higher than the 1 micron specification), and the droplets settle faster. This type of atomized sheet is more suitable for scenarios where there is low requirement for the suspension of mist drops. For example, household humidifiers - 5-micron droplets can quickly merge with the air to avoid the "white mist accumulation" caused by excessive fine particles, and at the same time reduce the problem of water stains caused by the adhesion of the droplets on the surface of the furniture. In aromatherapy machine applications, 5-micron droplets can carry more intense essential oil molecules, with a wider range of fragrance diffusion and a longer period of fragrance.
From the perspective of technical difficulty and cost, the Atomizer Plate with a particle size of 1 micron has more stringent requirements on material and process. Liandaqi uses high-purity alumina ceramic to make Ceramic Atomizer Plate substrate, and uses laser micro-engraving technology to process micro-scale atomization holes on the surface. In combination with customized Piezoceramic Transducer, it ensures uniform transmission of vibration energy and avoids particle size fluctuations caused by channel blockage. Although the process of 5-micron particle size atomization sheet is relatively simplified, Liandaqi still optimizes the ceramic sintering density to improve the consistency of atomization holes and ensures that the particle size deviation of each droplet is controlled within ±0.5 micron.
"The core of selection is to match scenario needs, rather than simply pursuing particle size." The head of Liandaqi Technology said that the company can provide 1 micron, 5 micron and other customized particle size Atomizer Plate solutions according to customer needs, such as supporting medical device manufacturers Nasal Spray Atomizer Plate, and supply high atomization 5 micron Ceramic Atomizer Plate to consumer electronics customers, so as to help various industries improve their product core competitiveness with technical adaptability.
