High Efficiency Ultrasonic Graphene dispersion Safety Easy Operation

Graphene dispersion

The purpose of graphene dispersion is to achieve immiscible dispersion, and its particles must be crushed and mixed strongly, which means that the formation of a new surface must overcome the resistance of surface tension to achieve. With the continuous development of technology, the problem of agglomeration has become a bottleneck for the continued development of graphene. Therefore, improving the dispersion of graphene has become an indispensable technical method to improve the quality, performance and process efficiency of products (materials).

Graphene is insoluble with many substances due to its surface inertness and has poor dispersibility. There are two ways to solve the bottleneck problem in the development of graphene: one is the large-scale production of low-cost and high-quality graphene raw materials; the other is the commercialization of graphene application. In the past two years, graphene has entered the stage of industrial application, and the upstream and downstream interactions of the industrial chain are crucial. We must carry out secondary development for users to solve common technical problems such as dispersion and molding, so that graphene is more "earthly".

 

Graphene powder has the characteristics of fine particle size, large specific surface area, high surface energy, increased surface atomic number and insufficient atomic coordination, which makes these surface atoms have high activity, extremely unstable, and are easy to agglomerate to form a number of links. The size of the interface is larger agglomerates. The agglomeration of powder is generally divided into soft agglomeration and hard agglomeration. The formation of agglomerates makes the nanoparticles cannot be uniformly dispersed in a single particle, and cannot exert their due nano characteristics, which has a very adverse effect on the application performance of the nano powder.

Application of Ultrasonic Graphene Disperser

 

(1) Ultrasonic graphene dispersion machine

The core content of the ultrasonic graphene disperser is how to solve the problem of particle agglomeration. Graphene is insoluble with many substances due to its surface inertness and has poor dispersibility. It is very difficult to obtain individual dispersed particles. How to uniformly disperse the particles into the matrix is ​​the key technology of graphene dispersion technology.

 

(2) How to use an ultrasonic disperser to disperse graphene

Ultrasonic graphene disperser uses ultrasonic cavitation to disperse agglomerated particles. It is to put the particle suspension (liquid) to be processed into a super-strong sound field and process it with an appropriate ultrasonic amplitude. Due to the inherent characteristics of agglomeration of powder particles, for some powders that are not well dispersed in the medium, an appropriate amount of dispersant can be added to maintain a stable dispersion state, which can generally reach tens of nanometers or even smaller. This product is especially effective for dispersing nanomaterials (such as carbon nanotubes, graphene, silica, etc.).

Introduction:

Ultrasound is an elastic mechanical vibration wave, which is fundamentally different from electromagnetic waves. Because electromagnetic waves propagate in a vacuum, and ultrasonic waves must propagate in the medium, the entire process of expansion and compression occurs when passing through the medium.
In liquids, a negative pressure is created during the expansion process. If the ultrasonic energy is strong enough, the expansion process can create bubbles in the liquid or tear the liquid into small cavities. These cavities are closed instantaneously, and an instantaneous pressure of up to 3000 MPa is generated when the cavity is closed, which is called cavitation. The entire process is completed in 400 μs.
Cavitation refines substances and makes emulsions, accelerates target ingredients into solvents, and improves extraction rates. In addition to cavitation, many secondary effects of ultrasound are also conducive to the transfer and extraction of target components.
The significance of cavitation is the reaction that occurs when a bubble bursts. At some points, the bubbles no longer absorb the ultrasonic energy, and implosion occurs. Gases and vapors in bubbles or cavities are rapidly adiabaticly compressed, resulting in extremely high temperatures and pressures.
The volume of the bubble is extremely small compared to the total volume of the liquid, so the heat generated is instantly dissipated, and it will not have a significant impact on environmental conditions. The cooling rate after the collapse of the cavity is estimated to be about 1010 ° C / s.
Ultrasonic holes provide a unique interaction between energy and matter. The resulting high temperature and pressure can lead to the formation of free radicals and other components.
In a pure liquid, when a hole is broken, it always remains spherical due to the same surrounding conditions; however, close to the solid boundary, the breakage of the hole is non-uniform. Kinetic energy, which moves in the bubble and penetrates the bubble wall.
The impact force of the jet on the solid surface is very strong, which can cause great damage to the impact area, resulting in a highly active fresh surface. The impact force produced by the burst bubble deformation on the surface is several times greater than the impact force generated by the bubble resonance.
The above-mentioned effect of ultrasonic waves is very effective in extracting various target components from different types of samples.
The high temperature and pressure generated on the contact surface between the organic solvent and the solid substrate by applying ultrasonic waves, plus the oxidizing energy of the free radicals generated by ultrasonic decomposition, etc., thereby providing high extraction energy.

 

Application:

(1) Compared with conventional extraction methods, ultrasonic extraction technology has high extraction efficiency and short extraction time;
(2) Ultrasonic extraction is not easily limited by the use of solvents, allowing the addition of co-extractants to further increase the polarity of the liquid phase and improve the extraction efficiency;
(3) Compared with supercritical CO2 extraction and ultrahigh pressure extraction, the ultrasonic extraction equipment is simple and the extraction cost is low;
(4) In most cases, the ultrasonic extraction operation has few steps, the extraction process is simple, it is not easy to cause pollution to the extract, and the extraction temperature is low, which is suitable for the extraction of heat-sensitive target components.
