2  Working principle

The working principle of ultrasonic spraying is to convert the high-frequency electric energy generated by the ultrasonic generator into the mechanical energy of high-frequency vibration (ie, ultrasonic vibration) through the ultrasonic nozzle, and use the atomizing function generated by the ultrasonic vibration in the liquid to flow through the front end of the ultrasonic transducer. The liquid is atomized to produce micron-sized fine droplets; the compressed gas of appropriate pressure is introduced to make the mist particles smaller and evener under the action of the airflow, and at the same time guide the running direction of the mist particles, and increase the operating power of the atomized particles. In order to achieve the purpose of precision spraying on the surface of the object to be coated.
3. Technical application

3.2 Applicable liquid (liquid compatibility)

2.1 nozzle selection
Because of the characteristics of ultrasonic atomization, it is generally suitable for liquid or liquid-solid mixture with a slightly lower viscosity (the amount of tiny particles is mixed in the liquid). Generally, the higher the ultrasonic vibration frequency, the smaller the atomized particles, but the electric power is also It becomes lower and the amount of atomization becomes smaller accordingly. If the vibration frequency is between 30 kHz and 100 kHz, a particle size of about 60 μm to 20 μm can be produced correspondingly. By adjusting the concentration and viscosity of the liquid (or liquid solid) to be sprayed, the amount of liquid supplied, the pressure of the deflecting gas, the relative operating speed of the spray head or the spray platform, the electrical and physical parameters such as the ultrasonic vibration frequency and power can reach sub-nanometer to micron. Grade film thickness.
Because the atomized particles are fine, the surface activity of the particles is high, and the proper gas flow pressure is adjusted, and each particle can be well adsorbed on the surface of the sprayed object without rebound and spillage loss, thereby ensuring uniformity of spraying and The utilization rate of spray materials (95%-99%).
Different types of nozzles can be selected according to different spraying applications and requirements. The nozzles are generally divided into fluid passage type, surface drainage type and extrusion type according to different structures. Generally speaking, the fluid passing type is suitable for the uniform spraying of small and medium areas, and is particularly suitable for the spraying of the liquid-solid mixture. Before the atomization, the ultrasonic vibration of the transducer is stirred first, and the mixing is more uniform. The surface drainage type is suitable for large area rapid spraying; the extrusion type is generally suitable for a small range of linear spraying.

Ultrasonic spray for solution type:
Different liquids have different viscosity and intermolecular binding force, or different mixed liquids (including liquid-solid mixture) have different mixing ratios, which have a great influence on the atomization of ultrasonic waves, and some even cannot be atomized at all. At present, there is no clear application rule to distinguish the specific types of liquids in detail. It is still necessary to carry out comparative tests on different frequencies, different powers, different concentrations, different temperatures, different flow rates and other related parameters for specific solutions.
But through some experiments, we can still find some thicker common categories, namely:
● Pure one-component liquids, such as pure water, ethanol, acetone, bromine, etc., with a viscosity below 100 CPS.
● A variety of liquid mixed solutions: such as water-based solvents (dilute acids, dilute alkalis, halogens, low-concentration salts), oligomeric alcohols, ketones, aldehydes as solvents (polymerization) Type) and so on. In particular, the solution of ethanol, acetone and methyl ethyl ketone as the solvent has the best atomization effect.
● Liquid-solid mixture solution: such as nano-scale C-Pt/alcohol mixture, bead polymer/water, low concentration coal slurry/water, silica gel/ethanol, suspension, etc.
among them:
For single-component liquids, the main effect on the degree of atomization is viscosity, and the viscosity is preferably less than 100 CPS.
For a mixture of multiple liquids, in addition to viscosity, there are also solubility characteristics and concentration in the solution, such as high polymer chains with very long molecular chains (when the droplets are separated from the entire liquid and then form an atomized state, those Polymer molecules block the formation of such discrete droplets).
For the liquid-solid mixture solution, in addition to the solvent itself, there is a solid concentration (less than 40%), a solid particle size (below 1/10 of the ultrasonic atomized particle size at this frequency), and between the solid particles and the solvent. Affinity (such as suspension status) and so on.
    Known ultrasonic sprays are not suitable for solution types:
High concentration liquid-solid mixture (solid content greater than 40%), polymer type, such as lipids (such as epoxy resin, polyurethane, polyene). In particular, it is difficult to atomize the epoxy resin solution, and the effect of uniform atomization cannot be basically achieved.
