1.Washing Solution: configuring solution with pH value 11.0 ± 0.1 (you can use the mass fraction of 0.004% NaOH Solution) , and heat solution up to (45±2)℃;
2.Immersion: specimen will be fixed ion rotation device as picture below, and then place specimen into the solution.(Height from Cell center to solution surface is 300mm ± 10mm, immersion for 0.5h, and to maintain the solution temperature at(45 ± 2) ℃;
3.Stirring: drive the rotation deveice for 0.5h, rotational speed 60r/min;
4.Dehydration: remove solution and drive the rotation device for 10min, rotational speed 800r/min;
5.Drying: put specimen into a high temperature chamber for 0.5h with temperature control at (45 ± 2) ℃;
6.Charge if necessary.
