High Performance Ultrasonic Graphene Dispersing System

High Performance Ultrasonic Graphene Dispersing System

Ultrasound creates acoustic cavitation, which produces violently imploding vacuum bubbles, causing shock waves, microjets and strong shear forces as well as extreme local temperatures (~5,000 K)and pressures (~1,000 atm). These extreme conditions result in exceptionally efficient mixing, yielding nanoemulsions with very small droplet sizes and enormous contact areas between all components.


High Performance Ultrasonic Graphene Dispersing System



Description:

 

The development of graphene industry demand high quality graphene urgently;(The traditional way of producing need to add more oxidant and reducing agent, while the ultrasonic exfoliation of graphite can greatly reduce the additive, greatly improve the puirty and reduce the size of graphene.)

 

Altrasonic equipment focused on the r&d of high power ultrasound applications.

Altrasonic has absolute leading core technology, the most stable and mature manufacturing technology, rich experience, can provide direct ultrasonic application scheme demonstrate, structure design, system configuration and related parts production.

Altrasonic equipment cooperated with the key graphene manufacturers, applied the ultrasound equipment in graphene preparation process of industrialization firstly, and make the ultrasonic be a good supporting to the large-scale preparation of the high quality and low cost graphene materials.

Graphene With Ultrasonic: 

 

Currently we use two step exfoliation can obtain high concentration graphene dispersion, second ultrasound in 30 hours reached the max concentration ---- 20 mg/ml, the instantaneous concentration as high as 63 mg/ml.

 

After using various methods, the graphite expansion and the space between graphene sheets increases, the Vader waals forces between inter-layers reduce, at the same time use the liquid phase exfoliation can make graphene production rate greatly increased, and also can use water as solvent to obtain graphene, has a broad  industrial prospect.Up to now, several companies use this way to achieve large production of graphene.

 

Through ultrasonic equipment, the surface of graphene reach 500 ~ 1000

m2 / g, thickness in 0.55 ~ 3.74 nm, the purity is more than 95 wt %, straight in: 0.5 3 microns, layer number less than 10. 

 

Advantages:

 

1. Core parts with Titanium materials

2. Ultrasonic horn with different size and type for selection

3. Matching with digital generator, auto-tuning, auto search frequency

4. With automatic alarm protection, easy to operate

5. Power adjustable from 1% to 99%

6. Amplitude stability, long working hours, radiation area is increased 2.5 times than traditional tools

7. Provide consulting services and custom reactor designs
