摘要: 叙述了双喷嘴乳粒发生器的工作原理、设计关键点及设计思路,利用该发生器开展了双层乳粒的制备实验研究工作。研制的双喷嘴乳粒发生器在喷嘴处的3层管的位置能够通过简单调节达到同心,使得双层乳粒包覆的可靠性得到提高。研究了制备的乳粒的分散性和稳定性,并分析了形成双层乳粒的油相和水相的流速比,结果证明:利用所研制的双喷嘴乳粒发生器可以容易地制备出单分散性双层乳粒,油相与水相的流速比为0.3~15.0时,可形成双层乳粒。Abstract: A double-nozzle emulsion particle generator is developed to synthesize monodispersed ICF capsules. The working principle of the generator, the key designed parts, and idea for it are described. With this set-up, the reliability of double-layer particle encapsulation is increased simply by adjusting the concentricity of the three-layer tubes at the nozzle. Initial experiments show that monodispersed double-layer emulsion particles can be easily synthesized, and the flow-velocity ratio of oil phase to water phase, at which double-layer emulsion particles would be formed, ranges from 0.3 to 15.0.
