preparation example Construction

[0038] The method for preparing liquid marbles (or other macroscopic liquid droplets existing in the gas phase) of the present invention will be described below with reference to the accompanying drawings. First, optionally, waxing or other hydrophobic treatment can be performed on the inner surface of the top plate 5 of the vibrating plate feeding device 20; the highly hydrophobic solid particles (powder) 13 are laid on the bottom, and the surface is covered at a certain height with a covering device. These solid particles (powder) cover up.

[0039] Next, the capillary glass tube 4 of the droplet generating device is inserted into the first opening of the covering device, preferably the end of the capillary glass tube 4 is no more than about 3 inches from the bottom of the vibrating plate top plate 5 (or the solid particles (powder) are laid on it). cm. Prior to this, the steps of preparing the droplet generating device 22 can also be carried out, such as injecting the liqu...

example 1

[0044] Combine below Figure 4 -5 describes an example of manufacturing the liquid marble of the present invention.

[0045] In this example, the liquid marble 15 is basically produced by the method described above. Wherein, the surface of the top plate is coated with wax so as to have certain hydrophobicity. And the above-mentioned highly hydrophobic solid particles (powder) are hydrophobic smoky silica gel powder, and the liquid solution is roughly a sodium alginate solution with a concentration of 4% (weight), and these sodium alginate solutions preferably have blue methylene blue . And the liquid droplets are produced by the liquid generating means to be less than or equal to about 2.5mm, and in this example the droplets are also substantially larger than about 2mm. In addition, in this example, the top plate of the vibrating plate feeding device can make the hydrophobic aerosol silica gel can have a peak vibration rate of at least about 300 mm / s and a vibration frequen...

Abstract

The invention provides a device applicable to the preparation of liquid droplets existing in gas phase macroscopically. The device is characterized by comprising an engine driven vibration device paved with hydrophobic solid particles and a liquid droplet generating device used for dripping the liquid droplets onto the vibration device, wherein the vibration device is constructed to enable the hydrophobic solid particles on the vibration device to be scattered through vibration so as to wrap the liquid droplets to form the liquid droplets existing in the gas phase macroscopically. In addition, the invention also provides a method for preparing the liquid droplets existing in the gas phase. The invention also relates to an application for preparing the liquid droplets existing in the gas phase macroscopically by adopting a vibration disk feeding device.

Description

technical field [0001] The present invention relates to the preparation of liquid droplets existing in the gas phase, in particular to a device and method for preparing macroscopic liquid droplets existing in the gas phase, especially a manufacturing device and method for liquid marbles. Background technique [0002] Currently, a so-called "liquid-in-gas droplet" is known. This "droplet in the gas phase" generally has a liquid core structure surrounded by a thin layer of solid, and thus appears to be a droplet in air (gas phase) from its ambient state Form, which differs significantly in many properties from a substance contained in a cavity formed by a solid substance. Therefore, liquid droplets present in the gas phase are suitable for many applications. Here, the term "liquid droplets present in the gas phase" as defined in the present invention shall comply with the above definition. [0003] The liquid droplets existing in the gas phase are generally divided into two...
