Utrasonic topic: "การไล่แก๊ส"
Degassing is the process of removing dissolved gases or air bubbles from liquids, which is essential in various industrial and laboratory applications to ensure the quality and accuracy of processes such as liquid chromatography, casting, the preparation of solutions as well as other products such as food or cosmetics. The presence of gases or air bubbles in a liquid can lead to issues like inaccuracies in measurements, defects in materials, or instability in chemical reactions, e.g. oxidation.
Ultrasonication promotes degassing and deaeration by using high-intensity, low-frequency ultrasound waves to create acoustic cavitation. When ultrasonic waves pass through a liquid, they generate rapid pressure changes, leading to the formation and collapse of microscopic bubbles, a process known as cavitation. The violent implosion of these bubbles dislodges trapped gas molecules from the liquid and promotes their coalescence causing them to rise to the surface where they can escape. This process significantly accelerates the removal of dissolved gases compared to conventional methods, making sonication an effective and efficient technique for degassing and deaeration in a variety of applications.
