Aluminum electrolytic brightener
●Main uses
This product is used for electrolytic polishing of various aluminum alloys, pure aluminum types and other types of aluminum. The cost-effectiveness is obvious and can achieve a mirror bright effect. After aluminum polishing, the luster is long-lasting and beautiful. Increased added value of the product.
●Main advantages
. The polishing fluid does not contain chromic acid and complies with current environmental protection requirements, saving investment in environmental protection equipment and wastewater treatment costs.
.The polishing current density is smaller than that of traditional processes, so the polishing fluid not only consumes less power but has a longer service life, and is more suitable for surface polishing of large aluminum and aluminum alloy parts.
Wide range of application: Suitable for pure aluminum and various types of aluminum alloys with silicon content greater than %.

. Configuration method
. The specific gravity of the polishing fluid before use is ..In the range. Calculate the amount of phosphoric acid to be added based on the volume of the polishing fluid to be prepared, the specific gravity of the polishing fluid and the weight ratio of phosphoric acid in the polishing fluid and add it.
Also calculate the weight of donkey additive required and add it.

●Notes
Whether to use stirring (cathode moving air stirring) during polishing mainly depends on the shape of the polishing piece. If the shape of the polishing piece is simple and the lateral width is narrow, stirring is not used. On the contrary, if the shape of the polishing piece is irregular Or the lateral width is large, especially when certain parts of the polishing part prevent gas from escaping to form air pockets, which affects surface polishing, stirring must be used. When stirring is used, the anode current density must be increased accordingly, otherwise it will be difficult to achieve high brightness on the polished surface.
During polishing, most impurities are deposited on the cathode surface, but some solid sludge generated by polishing still remains in the polishing fluid, so the polishing fluid needs to be filtered regularly to remove impurities.
During the polishing process, due to the electrolysis and volatilization of water produced by phosphate and the entrained loss of polishing fluid, it is necessary to continuously replenish phosphoric acid and Zhengbang brand aluminum electrolytic additives.
The original specific gravity of the polishing fluid after preparation and before use is within the range of. During the operation of the polishing tank, the specific gravity of the polishing fluid should be controlled within the range of. If the specific gravity of the polishing fluid is too high, it means that the water content of the polishing fluid is insufficient. On the contrary, if the specific gravity of the polishing fluid is too low, it means that the water content of the polishing fluid is too high and the phosphoric acid content is too low. Often using a hydrometer to measure the specific gravity of polishing fluid is an effective means to control the concentration of polishing fluid components and polishing quality.
Long-term polishing at a higher anode current density may cause the aluminum content in the polishing fluid to be too high (the presence of semi-molten material on the top of the polishing fluid is a sign of excessive aluminum content). At this time, the polishing fluid must be partially replaced with a new one. To reduce the aluminum content in the polishing solution.
