Maintenance and Management of Tank Liquid
When the impurities exceed a certain limit, the high current parts become dull or perforated, and the low current parts turn white and cannot be coated. The coating is rough. At this time, only 0.5mLA hydrogen peroxide (30%) needs to be added, followed by 1-2g/L zinc powder and activated carbon. After thorough stirring, let it settle and then remove the cylinder foot to restore normal operation. You can also use the WZN acidic impurity remover from Aobang Company: 1-2g/L, which can be circulated and filtered in the filter machine, and the effect is good! No need to clean the cylinder.
