Description
Technical field
The invention belongs to drop microreactors and emulsion template method microballoon/capsule forming technique application field, and in particular to one
The drop of kind simulated microgravity turns round curing reaction system.
Background technology
In microreactor, medicine controlled releasing, catalyst carrier, bioactivity kind loading, laser inertial confinement fusion（ICF）Target
In equal fields, microballoon/capsule of hundred microns to several millimeters grain sizes is widely used.Especially, hollow sphere polymer is as laser-produced fusion
Target mandrel material and fusion energy target fuel container are in great demand, and high to sphere quality requirements.With laser driver
Power is increasing, and prepared by the polymer microballoon batch of the regular millimeter magnitude of geometrical morphology to centimetres become target field processed
One of bottleneck." top-down " such as traditional mechanical agitation, ultrasound, spraying and film emulsifications（top to down）Method it is equal
It is difficult to bulky grain/ball that batch prepares monodisperse degree height and structure-controllable, and often step is more, time and effort consuming.In recent years,
" bottom-up "（bottom to up）It is micro-（micro-）/ milli flow control（milli-fluidic）Drop forming technology for
The grain size of grain/microballoon has unique advantage with geometry regulation and control.Either which kind of method, all using emulsion droplet as template into
Row curing molding makes microballoon/capsule.Wherein, double/multiple emulsion in-situ solidifying forming process complicated difficult control, lotion survival rate
It is low, product ball sphericity and concentricity（Evenness of wall thickness）It is difficult to improve, restricts the preparation and application of ICF target capsule of fusion.
Compared with micro/nano level drop, even more large-sized drop itself rheological characteristic of millimeter magnitude is complicated, gravitational settling
It is more obvious with buoyancy effect.Wherein, double/multiple emulsion system is more complicated, and thermodynamics is extremely unstable, density stratification effect etc.
Great risk and uncontrollability are caused, is brought to prepare the even more large-sized polymer hollow microsphere of millimeter magnitude and microcapsules
Huge challenge.For this purpose, the drop neutral buoyancy technology and the physical properties such as emulsion system viscosity and interfacial tension of density matching
Parameter control technique is studied earliest.On this basis, Tsinghua University is burnt using the partially fluid-filled round bottom of 30 degree of overturning angle rotations
Bottle is curing reaction container, and heating water bath cures the polystyrene for being prepared for about 2mm grain sizes（PS）Hollow ball, but its flow field is limited
In its container shapes, it is unsuitable for big grain size emulsion dispersion.American National dot center and China Engineering Physics Research Institute's laser-produced fusion
Research center is prepared for about 3mm grain sizes using partially fluid-filled cylinder curing reaction container is rotated horizontally by heat curing techniques
Polydivinylbenezene（PDVB）The polystyrene of hollow foam ball and 2mm grain sizes（PS）Hollow ball and poly- Alpha-Methyl benzene second
Alkene（PAMS）Hollow ball.In addition, American National dot center and University of Rochester etc. obtain about 2mm using electrophoresis technology placed in the middle
The resorcinol-formaldehyde of diameter（RF）With polyhydroxy methyl methacrylate（TMPTA）Hollow ball.Currently, electrophoresis technology placed in the middle by
System dielectric constant limits, and also mainly for the preparation of 2mm or less hollow microspheres, and its process introduces increasingly complex control ginseng
Number.Studies have shown that being based on density matching technique and emulsion system physical property, additional flow field perturbation action is optimization lotion solidification
The effective means of process.However, rotating part filling liquid technology often obtains Turbulent Flow Field, emulsion droplet makees nothing under eddy current effect
The strenuous exercise of rule, lotion occur compared with large deformation, heat and mass aggravation, and system density mismatch causes demulsification serious, is unsuitable for milli
Rice magnitude and more large-sized emulsion-stabilizing disperse, and solidification process later stage micelle mostly occurs reunion, causes microballoon yield extremely low,
It is particularly disadvantageous for the longer system of polymerization time.Simultaneously as there are gas-liquid interface, supersaturated air can also encroach on lotion.
In contrast, the revolution bioreactor that NASA uses（RCCS）Simulated microgravity condition research biological tissue,
It turns round fully fluid-filled technology and often obtains hidden danger existing for the avoidable partially fluid-filled technology of Laminar Flow, more efficient.Sorry
It is require high target field processed not yet to cause enough concerns to technique in bulky grain/ball, big large time delay high-quality
The development and application of target ball.
Therefore, it is a kind of suitable for millimeter magnitude even a greater amount of grades that there is an urgent need for development, is capable of the drop revolution of simulated microgravity
Curing reaction system.
