Ultrasonic Dispersing Machine

Dispersion refers to the dispersion of powder into liquid to form various products (such as paint, ink, coating and other polishing media). Ultrasonic disperser can realize uniform dispersion, coagulation and grinding in laboratory or industrial scale. Different from other technologies, ultrasonic dispersing machine is an effective dispersion method with low cost and easy operation and maintenance.

Components of graphene-specific ultrasonic dispersing machine:
1. Ultrasonic vibration source (driving power supply): converts 50-60Hz mains power into high-power ultrasonic power supply and provides it to the transducer.
2. Transducer (controller, transducer): converts high-frequency electrical energy into mechanical vibration energy.
3. Amplitude rod: connects and fixes the transducer and the tool head, amplifies the amplitude of the transducer and transmits it to the tool head.
4. Tool head (introduction rod): transmits mechanical energy and pressure to the workpiece, and also has the function of amplitude amplification

Q: What are the main working functions of the ultrasonic dispersing machine/ultrasound extraction/ultrasonic emulsification machine?

A： Ultrasonic dispersing machine: with liquid as the medium, particles in the liquid are dispersed and agglomerated through the "cavitation" effect of ultrasonic in the liquid. Ultrasonic dispersion can be divided into lotion dispersion, namely liquid dispersion and liquid dispersion; And the dispersion of suspension, that is, solid and liquid. Its functions have been applied in many fields. Among them, ultrasonic wave is used as suspension for dispersion. For example, in the coating and plastic industry, titanium oxide is dispersed with water or solvent, and dyes are dispersed with molten paraffin; There is a Dispersion of drug particles in the pharmaceutical industry; And the dispersion of powder lotion in the food industry.

Ultrasonic extraction: ultrasonic extraction and separation is mainly to design a scientific and reasonable method to extract the new technology by using ultrasonic vibration according to the existing state of the effective components in the material and the polarity and solubility of the effective components. The solvent quickly diffuses to every corner of the surface of the solid material. The material contains organic components, which are completely dissolved in the solvent as far as possible to obtain a multi-component mixed extraction solution, and then use appropriate separation methods, the chemical components in the extraction solution are separated, then refined and purified. Through such a complete process, the final required monomer chemical components can be obtained.

Ultrasonic emulsification: Phacoemulsification refers to the process of evenly mixing two (or more) heterogeneous solutions under the action of ultrasonic energy to form a dispersion system, in which one liquid is evenly distributed in the other liquid to form an emulsion. The physical mechanism of breaking insoluble solids (or liquids) is ultrasonic cavitation. Ultrasonic cavitation effect means that a large number of bubbles will be produced in the liquid under the action of ultrasonic. Small bubbles will gradually increase with ultrasonic vibration, and then suddenly rupture and split. Tens of thousands of small bubbles continue to increase and burst again and again. As the liquid around the bubble rushes into the bubble at a high speed, strong local oscillation waves are generated in the liquid near the bubble, and local high temperature and high pressure are also formed, resulting in ultrasonic breaking and emulsification.
