Invention is suitable for carrying out preliminary screening to all kinds of dry hollow polymer microspheres and glass microsphere selecting.
Background technology
As a kind of releasable form of core, laser inertial confinement fusion（ICF）It is that current controllable thermonuclear fusion field is ground
The hot spot studied carefully.Its core concept is pressurized to fusion fuel using spherical implosion technology, so that fusionable material is reached a high temperature, is high
The plasmoid of density, and then realize fusion igniting.Based on symmetrical compression, fluid boundary unstability and laboratory diagnosis
Consider, ICF is tested to the quality of the tiny balloon as fusionable material container in sphericity, evenness of wall thickness, surface roughness
And doped level etc. proposes strict requirements.The fuel container applied in ICF experiments at present includes mainly glass
Tiny balloon and polymer hollow microsphere.
It is in combined high temperature xerogel microballoon prepares stove that dry gel method, which prepares globulation in the stove of hollow glass micro-ball,
It carries out.First, the dry of appropriate foaming agents content and particle size range is selected according to the diameter of target hollow glass micro-ball and wall thickness
Gel particles.Then, suitable carrier gas component, temperature and pressure are selected.Xerogel particles from feed zone enter high-temperature region after from
By falling, successively by heat absorption, encapsulation, foaming, refining, cooling procedure, it is finally deposited in the culture dish etc of collecting region, is obtained
Suitable for ICF target hollow glass micro-balls.
Dry gel method prepares the movement and physical chemistry that globulation in the stove of hollow glass micro-ball is an xerogel particles
The complex process that change of properties and its heat and mass transfer process between carrier gas influence each other and be coupled, any parameter control
The improper quality that can influence final HGM is made, or even hollow glass micro-ball can not be formed.Simultaneously in solution solute quality
Score, foaming agent addition, encapsulation region and baking zone temperature change, the factors such as speed of evacuation seriously affect glass microsphere
Wall thickness.Therefore, the glass microsphere Thickness Distribution made from same batch is larger, or even will appear a large amount of solid glass microballoons,
Difficulty is selected which increase particular wall thickness hollow glass micro-ball.
Currently, in polymer microballoon preparation process, the polymer that diameter is less than 500 μm is prepared using lotion microencapsulation techniques
Microballoon.However due in this kind of method human factor be affected, be made polymer microballoon geometric parameter wider distribution, this nothing
It doubts and increases polymer microballoon and select workload.
