Solution Debubbling Technology

In many industrial production and experimental processes, bubbles in aqueous solutions, solvent systems, and inks have long been a major challenge for companies and researchers. Although small, bubbles can cause a series of adverse effects, impacting product quality and reducing production efficiency. Therefore, effective debubbling technology is particularly important. The novel degassing membrane technology promoted by Guochu Technology provides innovative solutions for debubbling in solvent systems and inks.

Degassing membranes typically use hollow fiber membrane modules. In debubbling semiconductor electroplating solutions, they achieve gas-liquid separation primarily through their hydrophobic microporous membranes. Under vacuum or inert gas sweeping, dissolved gases penetrate the micropores and are carried away, thereby reducing the concentration of dissolved gases in the electroplating solution. When the electroplating solution containing bubbles flows through the degassing membrane module, gases dissolved in the solution (such as oxygen, nitrogen, etc.) preferentially permeate through the membrane, while ions and other solutes in the electroplating solution are retained, thus achieving gas-liquid separation. Its advantages include high degassing efficiency, durability and stability, easy integration, and chemical-free, environmentally friendly, and safe operation. It can precisely control the gas content in the electroplating solution, meeting the stringent process accuracy requirements of semiconductor electroplating, helping to reduce defects such as pinholes and pits during electroplating, and improving the performance and reliability of semiconductor devices. During the degassing process, it does not introduce new impurities or significantly affect the composition and performance of the electroplating solution, maintaining its stability and consistency.

In precision cleaning applications requiring high cleanliness, such as ultrasonic cleaning tanks, bubbles can refract or absorb ultrasonic energy, greatly reducing cleaning efficiency. Bubbles in the cleaning fluid interfere with the instantaneous velocity effect of the cleaning machine, diminishing the cavitation effect and cleaning rate produced by ultrasonic vibration. Especially when using cleaning agents for high-precision cleaning, achieving the desired cleaning effect requires reducing the bubble content in the cleaning fluid.

In the ink field, microbubbles entering the printhead are essentially "printing killers." These microbubbles can prevent nozzles from starting properly and leave defects on printed materials, severely affecting print quality. At the same time, gases and microbubbles dissolved in the ink slow down printing speed and reduce printing efficiency. For the printing industry, print quality and efficiency directly affect a company's competitiveness, so removing bubbles from ink is a problem that must be solved.

The novel degassing membrane technology of Guochu Technology (Xiamen) Co., Ltd. performs excellently in solution debubbling. It can significantly reduce the gas concentration in the solution, effectively remove bubbles, and solve various problems caused by bubbles.
