Intelligent Ultrasonic Spray Nozzle Pyrolysis Coating Machine System

Model: TMAX-FS03I-Intelligent Ultrasonic Spray Coater

1. Introduction

Ultrasonic spraying is a unique spray technology based on ultrasonic atomization nozzle technology. The sprayed material is initially in a liquid state (solution, sol, suspension, etc.), which is atomized into fine particles by an ultrasonic atomization device and uniformly coated onto the substrate surface with a carrier gas to form a thin film or coating.

Advantages over Traditional Spraying:

· Superior uniformity

· Thinner coating thickness

· Higher precision

· Reduced paint splashing

· Material utilization rate is over 4x higher than traditional methods

Applications: Qualitative experiments in scientific research laboratories, small-scale production, and thin-film fabrication.

2. Principle

The ultrasonic nozzle converts electrical energy into high-frequency mechanical energy via the piezoelectric effect, creating a standing wave that atomizes the liquid into uniform micron-sized droplets.

Key Features:

· Precise control of droplet size and distribution

· Rapid evaporation for high-surface-area particles and thin-film coatings

3. Structure and Power Control of Ultrasonic Atomization Nozzle

Structure:

· Nozzle body: Titanium (excellent acoustic properties, high tensile strength, corrosion resistance)

· Protective casing: 304 stainless steel (titanium optional)

Power Control:

· Vibration amplitude must be carefully controlled:

o Too low: Insufficient energy for atomization

o Too high: Liquid is torn and ejected unevenly

· Optimal input power: 1–15 watts

4. Droplet Size Distribution and Flow Rate

Droplet Size:

· Determined by nozzle frequency, liquid surface tension, and density (frequency is primary factor).

· Higher frequency → Smaller median droplet diameter.

· Distribution follows a normal curve (median, number-average, and volume-average diameters).

Flow Rate:

· Depends on liquid arrival speed (not pressure).

· Adjustment ratios:

o Large apertures: 5:1

o Small apertures: 10:1

5. Advantages

· High Stability: Titanium alloy and stainless steel construction; no wear, clogging, or noise.

· Material Saving: Minimal splashing; paint utilization >4x traditional methods.

· High Controllability: Precise flow rate and spray pattern control.

· Easy Maintenance: Self-cleaning; no moving parts or cooling required.

· Wide Applications: Fuel cells, solar cells, glass coatings, electronic circuits, chemical liquids, etc.
