Description

Technical Field

[0001] The utility model relates to the technical field of polymer material preparation, in particular to a coating device for diaphragm manufacturing. Background Art

[0002] A diaphragm is a thin film or material used in physical, chemical, or electrochemical applications. Its main function is to separate different phases or regions. Depending on the application, diaphragms can be divided into electrolyte diaphragms, reverse osmosis membranes (RO membranes), gas separation membranes, and biomembranes. Electrolyte diaphragms are used in batteries and fuel cells to separate the positive and negative electrodes to prevent short circuits while allowing ions to pass through. Reverse osmosis membranes (RO membranes) are often used in water treatment and seawater desalination, and can effectively remove dissolved salts and other impurities.
