Claim 5:
6. A preparation method of a seawater desalination-seawater extraction uranium membrane lining using the preparation device of the seawater desalination-seawater extraction uranium membrane lining according to claim 1 to prepare the seawater desalination-seawater extraction a uranium membrane lining, comprising the following steps: step 1: firstly the lining enters the first cleaning tank, wherein a temperature of a liquid A in the tank is controlled at 50° C., and a residence time is 300 s; step 2: the lining from the first cleaning tank enters the second cleaning tank, wherein a temperature of a liquid B in the tank is controlled at 35° C., and a residence time is 180 s; step 3: the lining from the second cleaning tank enters the first pure water tank, wherein a liquid in the tank is a pure water, a temperature is controlled at 30° C., and a residence time is 300 s; step 4: the lining from the first pure water tank enters the second pure water tank, wherein a liquid in the tank is a pure water, a temperature is controlled at 30° C., and a residence time is 360 s; step 5: drying, the lining from the second pure water tank enters the drying oven, wherein a temperature is controlled at 100° C., and a drying time is 540 s; step 6: restoring a circle shape, the lining from the drying oven enters into the central circular hole of the circular copper cylinder, a temperature is controlled at 165-195° C.; step 7: generating burrs, the lining from the central circular hole of the circular copper cylinder enters the burr generating machine for generating the burrs; step 8: fixing a length of the burrs, shear knives are used to fix the length of the burrs through a high-speed rotary, and a vertical burr length is controlled at 30-100 μm.
