How to use aluminum polishing solution?
5, original gravity before the polishing liquid after preparation without the use of in the range of 1.50-1.52, the groove in the polishing operation, the specific gravity of slurry should be controlled within the range of 1.50-1.65. Polishing liquid slurry high proportion indicating lack of water content; on the contrary, the polishing liquid ratio
4, the addition ratio of phosphoric acid and YB-66 additive is generally based upon the 70% :30% added, but should be measured after each addition slurry specific gravity, and then be adjusted according to the measurement results.
3, in the polishing process, due to the generation, water electrolysis and the loss of entrained volatile and polishing liquid phosphate, phosphoric acid, and so the need to constantly replenish YB-66 additive.
2, polishing most of the impurities deposited on the cathode surface, but there are still some polishing because of the resulting solid sludge left in the slurry, so need regular polishing liquid filtration to remove impurities.
1, whether to adopt the stirring polishing (moving the cathode, air stirring) depends on the shape of the polishing member: If the polished pieces of simple shape, the lateral width narrower, not using stirring; on the contrary, if the polishing member or irregularly shaped transverse width comparing large, especially when the case of certain parts of the polishing member impede the escape of gas to form a "bag" and affect surface finish mixing method must be used. In the case of stirring conditions, a corresponding increase in the anodic current density must, otherwise it is difficult to achieve high brightness polishing surface.
