Description
Technical Field
The utility model belongs to the technical field of experimental facilities, concretely relates to eccentric agitator is used to microemulsion system.
Background
The microemulsion method is a common method for synthesizing nano particles, and is characterized in that under the action of an amphiphilic molecular surfactant, two immiscible continuous media are fused to form emulsion microbubbles, each microbubble is used as an independent nano reactor, and the nano particles with controllable sizes are obtained through nucleation, coalescence, agglomeration and growth. Two mutually insoluble continuous media as reactants, wherein the micelle particles contained in the two continuous media collide with each other during the reaction, and exchange substances to initiate chemical reaction. Because the particle size of the water core in the microbubble is fixed, the water cores with different particle sizes can not exchange materials, and most of the energy absorbed by the water cores comes from the collision among the particles, the effective collision energy is obtained by controlling the effective collision times of the particles, and the method is an effective way for realizing the control of the morphology and the size of the nano particles.
Stirring is a common experimental means in a microemulsion method, the process of injecting energy into a microemulsion system by stirring is beneficial to breaking agglomeration among micelle particles, the current view is that the process of injecting energy into the microemulsion system by stirring is beneficial to generating nano particles with smaller sizes, which is mainly because the specific surface of small particles is larger and is easy to absorb the energy in the system, and the process of obtaining the nano particles with smaller particle sizes by improving the stirring speed is one of the common theories of the prior art, but the process of injecting energy by stirring is not only the generation of kinetic energy transfer, but also the exchange between another non-negligible energy, namely heat energy, exists, and in the process of injecting energy in the form of heat energy, the particles tend to aggregate and grow to form large particles.
The conventional stirring mode mostly adopts coaxial stirring, namely continuous stirring is carried out by taking the position of a stirring device or an extension line as an axis, and one view is that the stirring mode is favorable for forming a reaction system with uniform concentration in the emulsion and forming particles with uniform appearance. However, the stirring method still cannot control the generation of reaction heat, and in addition, the energy injected by stirring is too high to form nano wires or nano rods with stable and remarkable shapes by removing nano particles and other forms of nano particles such as nano wires or nano rods.
