1. Working Principle
Ultrasonic nano-dispersion equipment is mainly based on the cavitation effect of ultrasound. When ultrasound propagates in a liquid medium, a series of sparse and dense longitudinal waves are generated, causing the internal pressure of the liquid to change rapidly. In the negative pressure stage, tiny cavitation bubbles are formed between liquid molecules; in the positive pressure stage, these cavitation bubbles collapse instantly, generating local high temperature, high pressure, strong shock waves and microjets. This powerful energy acts on the agglomerates of nanoparticles, which can effectively break the interaction between particles and make them evenly dispersed in the liquid medium.
2. Outstanding features
2.1 Efficient dispersion: Compared with traditional dispersion methods such as stirring and grinding, ultrasonic nanodispersion equipment can achieve a more uniform dispersion effect in a shorter time. Its powerful cavitation energy can penetrate deep into the agglomerate and fully break up the nanoparticles, greatly improving the dispersion efficiency.
2.2 Nanoscale dispersion precision: This equipment can accurately disperse nanoparticles to the nanoscale size range, meeting the high-precision requirements for nanomaterials in different fields. Whether in biomedicine, electronic materials, cosmetics an
d other industries, it can provide a strong guarantee for product performance improvement.
2.3 Mild treatment process: The ultrasonic dispersion process is relatively mild and will not cause significant damage to the structure and properties of the nanoparticles themselves. This is particularly important for some environmentally sensitive nanomaterials, such as bioactive nanoparticles, organic nanomaterials, etc., which can retain their original characteristics to the greatest extent.
2.4 Easy and flexible operation: The equipment is simple to operate and easy to control. By adjusting parameters such as ultrasonic power, frequency, and processing time, it can be optimized according to different material characteristics and dispersion requirements to adapt to diversified production processes.
3. Widely used fields
3.1 Biomedicine: In drug research and development and preparation production, ultrasonic nano-dispersion equipment is used to prepare nano-drug carriers, such as nano-liposomes, nano-emulsions, etc. These nano-carriers can improve the solubility, stability and targeting of drugs, enhance drug efficacy, and reduce toxic side effects. For example, anti-cancer drugs are encapsulated in nano-liposomes and evenly dispersed by ultrasonic dispersion technology, which can be better taken up by tumor cells and improve the therapeutic effect.
3.2 Electronic materials industry: In the preparation process of electronic pastes, nano-coatings, semiconductor materials, etc., ultrasonic nano-dispersion equipment plays a key role. By evenly dispersing nano-scale metal particles, oxide particles, etc. in solvents or matrices, the conductivity, thermal conductivity, optical properties, etc. of the material can be improved to meet the development needs of the continuous miniaturization and high performance of electronic devices. For example, when preparing high-performance lithium-ion battery electrode materials, ultrasonic dispersion technology can be used to evenly disperse the active substances and improve the battery's charge and discharge performance and cycle life.
3.3 Cosmetics industry: In order to improve the efficacy and texture of cosmetics, nanotechnology is widely used. Ultrasonic nano-dispersing equipment is used to evenly disperse nano-level whitening agents, moisturizers, antioxidants, etc. in the cosmetic matrix, making them easier to be absorbed by the skin and enhancing the skin care effect of the product. At the same time, the texture of the cosmetics after nano-dispersion is more delicate, uniform, and has a better application feel.
3.4 Food industry: In the production of food additives and functional foods, ultrasonic nano-dispersing equipment helps to evenly disperse nano-level nutrients, probiotics, etc. in the food system to improve their bioavailability and stability. For example, dispersing nano-level vitamins, minerals and other nutritional enhancers in beverages can be better absorbed by the human body and meet consumers' demand for healthy food.
