XM-CHF-5A ultrasonic two-dimensional material disperser Introduction: Taking the preparation of graphene separation as an example, when ultrasound propagates in the liquid, the graphite slurry generates high-frequency oscillations, forming cavitation bubbles in the liquid phase. Due to the much larger size of graphite compared to cavitation bubbles, the collapse of cavitation bubbles near graphite is asymmetric, resulting in high-speed micro jets pointing towards the surface of graphite, causing local damage to its surface. High frequency ultrasound causes high-frequency oscillation in the graphite slurry, and due to the difference in oscillation frequency, multiple layers are formed in the container. The graphite is continuously peeled off into graphene, and gradually peeled off from the bottom layer to the upper layer. Finally, graphene is continuously separated from the upper layer Features: 1. Ultrasound sample volume: With different adapters, the volume of ultrasound samples can reach 2ml -50ml and a 1.5-liter triangular bottle 2. Applicable sample types: Applicable sample types include 5ml, 15ml, 20ml, and 50ml centrifuge tubes, which do not require the use of special materials (such as glass) consumables, saving experimental costs 3. The sample needs to be crushed in a closed container without producing infectious flying mist and without the need for additional insertion of an ultrasonic probe 4. Permissible number of single operations: Up to 6 groups of 20ml samples can be processed at a time, as well as beakers up to 1.5 liters, with different adapters required 5. During ultrasonic testing of the sample, it is necessary to be able to automatically rotate at a constant speed to ensure consistent fragmentation and dispersion of the sample Technical parameters: Instrument outer size: 400x220x380 (mm) Cleaning tank size: 176x168x150 (mm) Ultrasonic nominal power: 750 W, ultrasonic power 0-100% infinitely adjustable Ultrasonic frequency: 20 KHz/45 KHz mixing Heating power: 300W, temperature adjustable: room temperature -80 ℃ Time adjustable 1-480 minutes or normally open Magnetic stirring speed: 50-1500r/min Inlet and outlet water circulation system: Yes Power supply: 220V/50Hz Configure rotary motor, power: 5W
