    • The invention relates to a method for producing simple and compound emulsions having micrometre-sized, controllable diameters and coatings, using a device formed by elements having characteristic dimensions of the order of a millimetre. The emulsions are produced using the suction produced by the flow of a viscous liquid through the section of a millimetre-sized capillary tube. According to a parametric analysis, the liquid or the pair of liquids to be emulsified form a simple or compound steady capillary jet of micrometre diameter, by the action of the co-flow of the emulsifying liquid and the favourable pressure gradient produced. The jet breaks because of capillary instability, forming simple or compound monodisperse micro-drops. The invention disclosed in this description can be used in industrial sectors where the production of simple and compound, monodisperse, homogeneous emulsions having micrometric-sized, controllable diameters and coatings is an essential part of the process.
    • 本发明涉及使用由具有特征尺寸为几毫米量级的元件形成的装置来制造具有微米尺寸,可控直径和涂层的简单和复合乳液的方法。 使用由粘性液体流过毫米尺寸毛细管部分产生的抽吸产生乳液。 根据参数分析,通过乳化液体的共流和产生的有利压力梯度的作用,待乳化的液体或一对液体形成微米级直径的简单或复合稳定毛细管射流。 由于毛细管不稳定性,射流断裂,形成简单或复合的单分散微滴。 在本说明书中公开的本发明可以用于工业部门,其中生产具有微米尺寸,可控直径和涂层的简单和复合的单分散均质乳液是该方法的基本部分。
