120Khz Ultrassonic Fuel Cell Spraying Coating Nozzles with Focusmist High Frequency Nebulization

Description:

The gathering type ultrasonic nozzle is an ultrasonic atomizing nozzle with small spray width. The ultrasonic atomization nozzle technology is adopted, and the special contraction flow channel design will uniformly and centrally distribute the carrier gas, so that the ultrasonic atomized liquid mist is in the form of concentrated spray, thus reducing the spray area of the ultrasonic nozzle. Due to the small spraying width of the centralized ultrasonic nozzle, it is mainly suitable for various small and medium-sized spraying applications, complementing the Funsonic wide width spraying ultrasonic nozzle, and can be almost suitable for all different flat spraying requirements.

Parameters:

There is a certain correlation between the working frequency and amplitude of ultrasonic spraying machines and the viscosity of coatings. The viscosity of coatings refers to the degree of viscosity of coatings, which has a certain impact on the working frequency and amplitude of ultrasonic spraying machines. The following is the relationship between them:

1. Working frequency: Higher working frequencies are usually suitable for low viscosity coatings. This is because high-frequency vibrations can generate higher shear forces, effectively dispersing and spraying low viscosity coatings. For high viscosity coatings, higher frequencies may cause the coating to pass through the nozzle too quickly and not achieve sufficient dispersion.

2. Amplitude: The selection of amplitude is also closely related to the viscosity of the coating. Larger amplitudes are usually suitable for high viscosity coatings. Large amplitude vibration can provide stronger energy, making high viscosity coatings easier to disperse and spray. On the contrary, for low viscosity coatings, larger amplitudes may lead to excessive dispersion or spraying.

Overall, lower viscosity coatings typically require higher operating frequencies and smaller amplitudes, while higher viscosity coatings typically require lower operating frequencies and larger amplitudes. This can achieve effective dispersion and spraying of coatings, and ensure the uniformity and quality of the spraying effect.

However, the viscosity of the coating is only one of the factors that affects the selection of working frequency and amplitude. Other factors, such as the particle size, rheological properties, and required spraying effect of the coating, also need to be comprehensively considered. Therefore, in practical applications, it is recommended to conduct experiments and adjustments based on specific coating characteristics and technical parameters of ultrasonic spraying machines to find the optimal combination of working frequency and amplitude.
