Introduction

Ultrasonic degassing is an advanced process employed for removing dissolved gases from various materials, enhancing their quality and performance. This technology utilizes high-frequency sound waves to achieve effective degassing, which is crucial in industries where gas bubbles can compromise the integrity or aesthetic of a product.

Principles of Ultrasonic Degassing

The ultrasonic degassing process involves the generation of ultrasonic waves, typically ranging from 20 kHz to 100 kHz. When these waves pass through a liquid or molten material, they induce cavitation—a phenomenon where microscopic bubbles form and collapse rapidly. This action facilitates the release of dissolved gases, effectively purifying the medium.

Applications of Ultrasonic Degassing

Metals and Alloys

In the metal industry, ultrasonic degassing is crucial for removing hydrogen and other gases from molten metals like aluminum and steel. This process helps in reducing porosity and improving the mechanical properties of the final product. Parameters such as degassing time, typically ranging from 5 to 20 minutes, and ultrasonic frequency, commonly set at 20 kHz, are optimized based on the specific application requirements.

Polymers

Ultrasonic degassing is also applied during the polymerization process to eliminate trapped air bubbles, ensuring uniformity and integrity of the polymers. Usually, a frequency range of 40–50 kHz is used, and the process duration may vary depending on the viscosity and volume of the polymer.

Liquids and Chemical Solutions

In chemical solutions and various industrial liquids, ultrasonic degassing ensures the removal of unwanted gases that could lead to oxidation or affect reaction kinetics. The process parameters, including a frequency of 25 kHz and a processing time of 10-15 minutes, are selected to optimize the degassing efficiency.
