What are the advantages of piezoelectric ceramic series products in the application of ultrasonic cleaning?
2025-06-05
1. efficient energy conversion capability
The core characteristic of piezoelectric ceramics is the piezoelectric effect-high-frequency mechanical vibration is generated by electrical signal excitation, and electrical energy is efficiently converted into ultrasonic energy.
High frequency vibration advantage: can produce 20kHz ~ 100kHz above the high frequency vibration (far beyond the human hearing range), driving the cleaning fluid to form dense cavitation bubbles. Local high pressure (thousands of atmospheres) and high temperature (about 5000K) generated when bubbles burst can instantly peel off dirt, grease, particulate impurities, etc. on the surface of the object, and is especially suitable for deep cleaning of complex gaps and microporous structures.
High energy concentration: vibration energy can be accurately focused on the cleaning area, compared to traditional mechanical cleaning or sound wave cleaning, energy utilization rate increased by 30% to 50%, shorten the cleaning time while reducing energy consumption.
Compact and flexible 2. structure
Piezoelectric ceramic products are small in size and light in weight, and are easy to integrate into various cleaning equipment to meet the needs of diverse scenarios:
Modular design: The layout of piezoelectric ceramic transducers can be customized according to the size and shape of the cleaning tank (such as attached to the bottom of the tank, side wall or designed as a suspended module), and flexible adaptation to different specifications of cleaning equipment (such as small laboratory cleaning machines, large industrial cleaning lines).
Strong corrosion resistance: ceramic material itself has excellent chemical stability, can withstand acid, alkali and other corrosive cleaning liquid long-term erosion, prolong the service life of equipment (regular service life of up to 5 to 10 years).
3. precise and controllable cleaning performance
The vibration parameters (frequency, amplitude, power) of piezoelectric ceramics can be precisely adjusted by electrical signals to achieve "on-demand cleaning":
Multi-frequency switching: low frequency (20~40kHz): suitable for removing large pieces of dirt or hard particles (such as cutting fluid residues of metal processing parts), with strong cavitation effect and large impact force.
High frequency (above 100kHz): suitable for precision devices (such as optical lenses, semiconductor components) trace impurities cleaning, vibration is more delicate, to avoid damage to the fragile surface.
Wide range of adjustable power: from tens of watts to several kilowatts, the energy output can be adjusted for different materials (metal, glass, plastic, ceramics, etc.) and pollution levels to prevent excessive or insufficient cleaning.
4. green environmental protection and economy
Low noise and low pollution: ultrasonic cleaning mainly relies on physical cavitation effect, no need or reduce the use of chemical solvents, in line with environmental protection requirements; and vibration noise is lower than the traditional mechanical mixing (usually <85dB), improve the working environment.
Long-term cost advantage: Piezoelectric ceramic transducers have low maintenance costs (no wear of moving parts) and easy replacement.
Compared with solvent cleaning or manual cleaning, it can save more than 50% of the cost of consumables and more than 70% of the labor time, especially suitable for large-scale industrial applications (such as batch cleaning of auto parts and electronic components).
5. typical application scenarios
Ultrasonic cleaning technology for piezoelectric ceramics has been widely used in many industries:
Industry Application Scenario Advantages
Electronics Manufacturing Printed Circuit Boards (PCBs), Semiconductor Wafers, Precision Electronic Components Cleaning removes micron-sized particles to avoid short circuits or performance defects
Medical and pharmaceutical surgical instruments, glassware, laboratory consumables cleaning and efficient sterilization, in line with health standards
Deep cleaning of aerospace engine components and avionics withstands cleaning of complex structures to ensure equipment reliability
Dirt removal of jewelry, watches and watches movements Non-destructive cleaning to restore gloss
Cleaning of oil stains and metal debris from machining molds, gears and bearings instead of solvent immersion to reduce environmental pollution
6. technology development trend
With the progress of material science and control technology, piezoelectric ceramics are developing towards high frequency, intelligence and integration in the field of ultrasonic cleaning:
High-frequency: Development of MHz-level ultra-high frequency piezoelectric ceramics for nano-scale precision device cleaning (such as MEMS chips).
Intelligent: Combined with sensors and automatic control system, real-time monitoring of cleaning effect and dynamic adjustment of parameters.
Composite technology: combined with laser cleaning, plasma cleaning and other technologies to form a synergistic effect and improve the removal capacity of complex pollutants.
Summary
Piezoelectric ceramics have become one of the core technologies in the field of ultrasonic cleaning due to their efficient energy conversion, flexible adaptability, precise controllability and environmental protection and economic characteristics. Its advantages are not only reflected in the traditional industrial scene, but also show irreplaceable value in high-end precision manufacturing, medical and other emerging fields. In the future, with the technology iteration, the application prospect will be further expanded.
