Description

Nanometer material dispenser

Technical Field

The invention relates to a nano material dispersing technology, in particular to a nano material dispersing machine.

Background

The nanometer material is the focus field of the research of new materials at present, is the focus of the national basic industry, and the problem of nanometer material agglomeration is faced when various new materials are prepared by utilizing the nanometer material, and the nanometer powder agglomeration refers to the phenomenon that the original nanometer powder is mutually connected in the processes of preparation, separation, treatment and storage, and a plurality of particles form a larger particle cluster. Because the agglomerated particle size is small, the surface atomic ratio is large, the specific surface area is large, the surface energy is large, and the nano material is in an energy unstable state, fine particles tend to be agglomerated together and are easy to agglomerate to form secondary particles or even tertiary particles, so that the particle size of the particles is enlarged, and the original functions of the nano material are lost. The agglomeration of nanoparticles is generally divided into two types, one is soft agglomeration and one is hard agglomeration; the research on the mechanism of soft agglomeration indicates that the soft agglomeration is caused by van der Waals force and electrostatic force between molecules or atoms on the surface of nano powder, the acting force is weak, and the soft agglomeration can be depolymerized by some chemical action or by applying mechanical energy. The agglomeration of the nano particles in the liquid phase medium mainly depends on the action of adsorption force and repulsion force, and when the adsorption force is greater than the repulsion force, the particles are agglomerated.

The dispersion method of the nano agglomerated powder mainly comprises a physical dispersion method and a chemical dispersion method. The physical dispersion method mainly comprises high-speed shearing, grinding, ball milling, sand grinding by a sand mill and ultrasonic treatment; the chemical method includes addition of a surfactant, washing with strong acid and strong base, and the like.

The physical dispersion method, high-speed shearing, ball milling and sand milling by a sand mill mainly comprises the steps of applying mechanical friction and extrusion to agglomerated particles through a grinding ball medium to crack and crush the agglomerated particles, and the probability of extrusion and friction of the grinding balls and zirconium balls of the ball milling and sand milling to the agglomerated particles is low, so that the method needs to consume a long time, and has high energy consumption and low efficiency. In addition, these mechanical treatments, while cracking and breaking the agglomerates, may cause the agglomerates to be more densely packed and difficult to disperse, due to the different properties of the materials.

Compared with a high-speed shearing method, the method can avoid extruding the aggregate to be more compact, and the sheared particles are directly sheared into pieces. However, in the high-speed shearing method, the cutting edge of the shearing tool rotating at a high speed acts on agglomerated particles, the problem that the cutting edge of the shearing tool is abraded is very obvious, the shearing efficiency is rapidly reduced, and the abraded cutting tool drops metal micro particles to pollute the nano material. Some nano materials may be contaminated by metals to cause material performance changes, and some nano materials may form dangerous sources after being contaminated by metals, for example, contaminated metal particles in positive electrode materials and negative electrode materials of lithium ion batteries may cause fire and explosion.

The ultrasonic dispersion technology is widely used in the preparation of nano materials, when ultrasonic waves pass through liquid, generated mechanical waves push liquid particles to move to form expansion waves and pressure waves, when the expansion waves are large enough, the expansion waves push the liquid to form bubbles, a 20kHz ultrasonic transducer continuously forms 2 ten thousand expansion waves and pressure waves per second, and a series of superposed bubbles are formed in the action direction of the ultrasonic waves and are continuously superposed 2 ten thousand per second. The process of cavitation in the sound field is called from the production, growth and collapse of bubble nuclei. When the bubble grows in the sound field and resonates with the sound field, the bubble absorbs the energy of the sound field, and the period is only two ten-thousandth of a second for a short time; once the bubbles absorb energy, the bubbles are not synchronized with a sound field any more, the bubble surface and the next pressure wave generate impact, the bubbles are immediately collapsed within one-twenty-one-ten-thousand seconds, the collapsed bubbles generate air pressure, when the surrounding bubbles are compressed, high temperature is generated, the bubbles are influenced by the high temperature and compressed by gas, the bubbles form internal high pressure, and the process is continuously generated at 2 ten thousand/s. Aiming at the nano agglomerated particles, gas and liquid generated by ultrasonic cavitation effect permeate into gaps of an agglomerated interface in the agglomerated particles, and the gas and the liquid permeate into the gaps of the agglomerated interface in the agglomerated particles and are subjected to continuous superposition effect, so that gas and liquid expansion pressure is formed in the agglomerated particle particles, and cleavage and diffusion are performed according to the agglomerated interface, the effect is close to the end face of the ultrasonic wave emitting vibrator, the permeation speed of the gas and the liquid is higher, and the dispersion speed of the nano agglomerated particles is higher.

Research shows that the effect of the interface during ultrasonic cavitation is mainly reflected in that cavitation generates micro jet flow to impact agglomerated particles, bubbles are collapsed after being deformed by pressure before collapse, the bubbles are collapsed after being deformed by pressure to generate micro jet flow to impact the agglomerated particles, and the trickle velocity of the impact interface is very high, so that the surfaces of the agglomerated particles are collapsed and crushed; the effect is widely applied to ultrasonic cleaning, ultrasonic cell disruption and natural product extraction experiments.

The ultrasonic cavitation doing work of the ultrasonic wave is mainly characterized in that:

the energy transfer distance is very limited, the effective distance of approximate linear propagation is limited to 3-5 mm, and different media are different; the kinetic energy of the micro-jet flow generated by the collapse of the bubble in the liquid is quickly attenuated, and the range of the micro-jet is limited within the range of mum. Although the micro-jet range is very small, the energy is concentrated, local high temperature and local violent vibration can be formed, the equal pressure effect of shock waves is caused, and the function of strengthening mass transfer reaction is achieved. The characteristic is suitable for extracting the effective components of natural products and biological fermentation products; compared with the conventional extraction method, the ultrasonic extraction has the advantages of extraction time period, no need of heating, and capability of avoiding damage of high temperature to effective components. However, because the energy transfer distance is very limited, the effective distance of approximate linear propagation is limited to 3-5 mm, and the method is limited to the preparation of small samples in a laboratory, and the industrial mass treatment of materials is difficult to realize; patent application number 201921481511.4 ultrasonic cell crusher for extracting 1-deoxynojirimycin in mulberry leaf is in order to overcome that the existing ultrasonic cell crusher only has an ultrasonic probe to crush the cell sap in the container, the problem of uniform crushing can both be realized to the cell in the liquid in the container is difficult to realize, the improvement is step distribution multiunit ultrasonic probe, it rotates to drive ultrasonic probe by driving motor, the ultrasonic wave breakage can all be carried out to the cell of each height aspect of cell sap in the container, broken coverage has been promoted. Although the coverage area of the cell liquid crushing device is increased relative to the coverage area of a single ultrasonic probe, the distance between the cell liquid in the container and the end face of the wave emitted by the ultrasonic probe cannot be within 3-5 mm, the cell liquid in the container cannot be crushed, the components contained in the cell liquid in the container are incompletely extracted, the extraction yield is reduced, the materials are wasted, and the cost is increased.
