Have the performances such as better mechanics, electricity, heat conduction, by reasonably disperseing, consolidation method, the graphene of higher performance can be obtained
Metal-base composites.
Since graphene surface is almost without functional group, it is difficult to be scattered in alone in water or organic solvent, emulsification pretreatment is
In the case of being aided with emulsifier under the action of high speed shear, the quick, evenly dispersed of two or more objectionable intermingling phases is realized
Effect.
High-shearing dispersion emulsifying machine is exactly efficiently, rapidly and uniformly by a phase or multiple phases (liquid, solid, gas)
Enter the process of another immiscible continuous phase (liquids in general).And each phase is immiscible in general.
When external energy inputs, two kinds of material recombinations become homogeneous phase.High tangential velocity and high frequency caused by rotor high speed rotation
The powerful kinetic energy that mechanical effect is brought, make material in the narrow gap of stator and rotor by strong machinery and aquashear, from
Heart extruding, hits tearing and the comprehensive functions such as turbulent flow at liquid layer friction, forms suspension (solid-liquid), lotion (liquid/liquid) and
Foam (gas/liquid).To keep immiscible solid phase, liquid phase, gas phase common corresponding maturation process and appropriate additive
Under effect, the dispersion and emulsion of moment uniform, fine finally obtains stable high-quality product by moving in circles for high frequency.
