| titleOfInvention | Reinforced three zone microporous membrane manufacturing system and method |
| abstract | (57) Abstract: A system and method for producing a reinforced three-region microporous phase change membrane is disclosed, wherein the film comprises a plurality of membranes in at least one of the three regions from a single source dope batch. Of different hole sizes. The system and method dispense at least a single source batch dope in a vessel, preferably maximizing the ratio of non-solvent to solvent for a given weight percent of polymer, which is used in the microporous phase change membrane manufacturing process. For use, a three-region phase inversion film is made, the film having one of a plurality of different predetermined pore sizes in any or all of the three regions. At least one source dope batch is controllably dispensed in at least one vessel, the temperature of the dope does not exceed a predetermined maximum mixing temperature, and the dope is relatively cool (less than the mixing temperature) suitable for storage. ). A small amount of the dope from at least one source batch is also heated in at least one temperature controller to a temperature no higher than any of the plurality of target temperatures, wherein the target temperature is at least one of the microporous phase change membranes. It corresponds to the particular desired pore size to be formed in one area, and the film is obtained by operation at a doping station. The dope is then cooled to about room temperature or to a temperature that provides a suitable and / or optimal coating viscosity. At least one doping application device is connected to the at least one temperature control device, and any of a plurality of different pore size dopes from the temperature control device are transported to the doping station and the three-region reinforcement to be produced. It applies to any of the three regions of the microporous membrane. |
