Latest Patents

Fenjuan Xiangli 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 hydrophilic treatment of a porous PTFE membrane to create a hydrophilic base membrane. It continues with the cleaning of a chelating resin using hydrochloric acid, sodium hydroxide, and deionized water, followed by drying. The cleaned resin is then ground and sieved to produce a powder. This powder is mixed with polyisobutylene and a polyhexafluoroethylene emulsion, and vacuum defoaming is performed to create a membrane coating solution. The hydrophilic base membrane is coated with this solution to form the chelating membrane. Finally, the membrane is washed with hydrochloric acid, sodium hydroxide, and pure water until neutral, and then dried and stored.
