The nozzles of the atomization spraying equipment all work at a specific frequency, which determines the size of the droplets. The nozzle of the atomization spraying equipment is made of very high-strength titanium alloy and stainless steel materials, making it very resistant to chemical attack and providing better performance. The liquid is introduced into the atomizing surface through a non-clogged feed tube extending along the length of the nozzle, generating vibrations in the liquid on the atomizing surface.
In order to atomize the liquid, the vibration amplitude of the atomizing surface must be carefully controlled. If the amplitude is too high, the liquid will be torn apart and a large amount of "fluid lumps" will be ejected. Only in a specific narrow range can the low-velocity fine mist peculiar to precision atomization spraying equipment be produced.
Factors affecting the effect of atomization spraying equipment:
1. Droplet size
The size of the droplets of the same solution during atomization spraying is determined by the vibration frequency of the nozzle of the atomization spraying equipment, the surface tension and density of the atomized liquid, where the frequency is the determining factor, the higher the frequency, the median diameter of the droplet size The smaller the atomization particles are, the size is 15-25 microns.
2. Atomization success or failure
The liquid is introduced to the atomizing surface through the non-clogging channel of the nozzle length, and the liquid appearing on the atomizing surface absorbs the vibration energy. The vibration amplitude must be carefully controlled. When it is lower than the so-called critical amplitude, there is not enough energy to produce atomization. But if the vibration is too high, the liquid will be torn apart and sprayed out in lumps. Only the amplitude within a specific input power range can produce an ideal atomization effect. For atomized spray equipment, the input power level is generally from 10 to 15 watts.
3. Atomization flow
The flow range of the nozzles of atomization spraying is generally relatively large. Because the precise atomizing spraying process does not depend on pressure, the amount of liquid atomized by the nozzle per unit time of the same solution is mainly controlled by the liquid delivery system used in combination with the nozzle.
4. Liquid compatibility
There are several factors that affect the ability of a liquid to atomize, including the viscosity of the liquid, the solid content, the degree of mixing of different components, and the dynamic characteristics of the liquid. At present, there is no strict law that can influence the actual degree of atomization of atomization spraying equipment. Some liquids seem to atomize very easily at first, but in fact it proves to be very difficult, while other liquids seem to be impossible, but they atomize very well.
5. Paint viscosity
The application viscosity of atomization spraying paint is generally slightly lower than that of air spraying, in order to improve the atomization effect, so that the paint mist is easy to surround and deposit along the direction of the power line.
