Ultrasonic dispersion has many help, benefits and significant effects, as follows:
1. Efficient dispersion:
A. Fast dispersion: ultrasonic waves can disperse particles evenly in a medium such as liquid or gas in a short time. For example, when preparing paints, inks and other products, the pigment particles can be quickly dispersed evenly, greatly improving the production efficiency, and saving a lot of time compared to the traditional mixing and other dispersion methods.
b. Fine dispersion: the high-frequency vibration and cavitation effect generated by ultrasound can break the agglomeration particles into smaller sizes, making the degree of dispersion higher and achieving micron or even nanoscale dispersion effects. This helps to improve the quality and performance of products, such as in the preparation of nanomaterials, ultrasonic dispersion is an important means.
2. Improve dispersion stability:
a. Uniform distribution: The microjet and shock wave generated by ultrasonic action can make the particles evenly distributed in the medium, reducing the accumulation and precipitation of particles. After ultrasonic dispersion of the suspension, the particles can maintain a stable dispersion state for a long time, extending the shelf life and service life of the product.
b. Reduce interfacial tension: ultrasound can reduce the interfacial tension between the particles and the medium, making the particles more easily wetted and wrapped by the medium, thus enhancing the stability of dispersion. This is particularly important for the dispersion of some highly hydrophobic particles in water-based media.
3. Wide applicability to materials:
A. Suitable for a variety of materials: whether it is solid particles, liquid droplets or gas molecules, ultrasonic can be effectively dispersed. For example, in the food industry, ultrasound can be used to disperse fat globules in dairy products and refine pulp particles in fruit juices; In the pharmaceutical industry, it can be used for the dispersion of drug particles and the preparation of suspension 4.
b. Not limited by the nature of the material: for materials with different viscosity, density and hardness, ultrasonic dispersion can play a better role. Even for high-viscosity materials, such as polymer solutions, adhesives, etc., ultrasonic waves can overcome the viscous resistance of materials and achieve good dispersion effects.
4. Easy to operate and control:
a. Simple operation: ultrasonic dispersion equipment is usually simple in structure, easy to operate and easy to use. Only need to put the material into the equipment, set the parameters of the ultrasonic wave, such as frequency, power, processing time, etc., the equipment can automatically carry out decentralized operation.
b. Parameter control: By adjusting the parameters of the ultrasonic wave, the dispersion effect can be accurately controlled. According to different materials and dispersion requirements, the ultrasonic frequency, power and processing time can be flexibly adjusted to obtain the best dispersion effect.
5. Energy saving and environmental protection:
a. Low energy consumption: Compared with some traditional dispersion equipment, such as high-speed mixers, ball mills, etc., the energy consumption of ultrasonic dispersion equipment is lower. This is because ultrasonic dispersion uses the energy of sound waves to achieve dispersion, and does not require a large amount of mechanical energy input, which can reduce energy consumption.
b. No pollution: there is no need to add additional chemical agents or dispersants in the ultrasonic dispersion process, so there is no chemical pollution. This is of great significance for some industries with high environmental requirements, such as food and medicine
