Latest Patents

Pingping Dai holds a patent for a "Preparation method for chelating membrane for purifying wet electronic chemicals." This patent outlines a detailed process that includes several steps. The method begins with performing hydrophilic treatment on a porous PTFE membrane to create a hydrophilic base membrane. Following this, a chelating resin is cleaned with hydrochloric acid, sodium hydroxide, and deionized water before being dried. The cleaned resin is then ground and sieved to obtain a powder. This powder is mixed with polyisobutylene and a polyhexafluoroethylene emulsion, followed by vacuum defoaming to create a membrane coating solution. The hydrophilic base membrane is coated with this solution to prepare the chelating membrane. Finally, the membrane is washed with hydrochloric acid, sodium hydroxide, and pure water until neutral, after which it is dried and stored.
