1. The principle of ultrasonic defoaming: the synergistic effect of physics and chemistry
The core of ultrasonic defoaming equipment is to use the physical energy of high-frequency sound waves (usually 20kHz-100kHz) to accurately intervene in the foam structure. Its mechanism of action can be analyzed from the following levels:
1.1 Vibration shear destruction : The high-frequency vibration generated by ultrasound forms shear force in the liquid, directly tearing the liquid film on the foam surface, accelerating the merging and rupture of bubbles.
1.2 Cavitation effect empowerment : When the cavitation bubbles caused by sound waves in the liquid collapse instantly, the released shock waves can further disintegrate the stability of adjacent foams.
1.3 Molecular intervention : High-frequency vibration causes the surfactant molecules (foam stabilizer) to rearrange, reduce the strength of the liquid film, and inhibit foam regeneration from the root.
2. Application scenarios: From clean production to cross-border innovation
2.1 Optimization of detergent production line: Integrating ultrasonic defoaming modules in the filling and dispensing process can reduce the frequency of downtime and cleaning caused by foam overflow, and increase production capacity by 15%-20%.
2.2 Food and beverage industry: Precisely control the foam height in beer fermentation tanks and dairy processing lines to avoid the risk of microbial contamination.
2.3 Breakthrough in environmental protection: Replace silicon defoaming agents when treating industrial wastewater to avoid secondary pollution and help achieve the "dual carbon" goals.
2.4 Semiconductor precision cleaning: Achieve contactless defoaming in the wafer cleaning process to ensure a high-cleanliness production environment.
