Latest Patents

Kehchyn Ho holds a patent for a method titled "Method for purifying fluoride etching solution by using hydroxide compound and ion exchange resin absorption." This method begins with a reaction using hydroxide gas or solution to achieve a balanced pH condition for the fluoride etching solution. The treated etching solution is then fed through a constant velocity pump to a basic anion exchange resin column. This process effectively removes various contaminants, resulting in a saleable product suitable for a wide range of industrial applications. The final solution is collected in a finished product storage tank. The degree of purification can be verified as needed, ensuring that ammonium fluoride, ammonium bifluoride, anhydrous hydrogen fluoride, and fluoride mixtures meet the requirements of different market applications. Additionally, the ion exchange resins can be regenerated to extend their useful life and system capacity.
