Description

A kind of alkaline zinc plating high purity electroplate liquid electrolytic plating pool

Technical field

The utility model relates to a kind of alkaline zinc plating electrolytic plating pool, especially a kind of alkaline zinc plating high purity electroplate liquid electrolytic plating pool.

Background technology

Electro-galvanizing is also named cold galvanizing, that workpiece is placed in electrolytic solution, that plated metal is separated out and is deposited on workpiece and forms coating, its coating is pot galvanize ratio comparatively, thinner, be generally 4-12 micron, the quality of coating is most important link, due to speed in the process of plating, distribution of current is uneven, the factor such as the dispersive ability of electroplating solution is not strong, the thickness of coating at a goods position can be caused uneven, and the corrosion resistance of coating depends primarily on thickness of coating and exposed environments, the coating that working conditions more badly needs is thicker, and the corrosion resistance of whole coating depends on that the weakest part of coating comprises the resistance to corrosion in the minimum place of local thickness, general present situation, thickness coating is added in order to obtain better solidity to corrosion, undoubtedly in the waste adding cost and zinc metal, and coating is thicker, the internal stress of coating is larger, coating easily comes off, also easily produce coarse, the flaw such as to burn, and the place that coating is excessively thin, low in glossiness, obfuscation, send out mist, easily show-through in the process of bright dipping and passivation.No matter from non-corrosibility, or outward appearance, the aspects such as machinability, all wish the homogeneity of the thickness improving product each position coating, reduce extreme difference.

The zinc-plated direct employing zine plate of conventional alkaline is as anode, and when anode quantity is very few, easy passivation is not dissolved, when anode quantity is too much, zinc concentration to be caused in solution to raise, and after anode dissolution shortens, conductivity can be affected, these all can affect the stability of plating solution, and due to the impact of time, have many foreign ions and produce, the metal ions such as such as cadmium, lead, copper, iron, time is longer, and the concentration of foreign ion is higher, and then affects quality product.Therefore just must develop one and can remove the highly purified electrolytic plating pool of foreign ion maintenance electroplate liquid in electroplate liquid, not find the same or analogous device with the utility model through retrieval.

Summary of the invention

The technical problems to be solved in the utility model is to provide one can remove the highly purified electrolytic plating pool of foreign ion maintenance electroplate liquid in electroplate liquid.

For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of alkaline zinc plating high purity electroplate liquid electrolytic plating pool, comprise a plating tank, plating tank comprises plating major trough and a molten zinc groove be connected with plating major trough by filter, plating tank inwall is provided with at least one positive plate, arranges a telescopic bar directly over molten zinc groove, telescopic bar bottom arranges an insoluble hanging basket, be provided with zinc ball in hanging basket, its innovative point is: molten zinc groove sidewall arranges at least one electrolysis cathode; Described electrolysis cathode is a spirrillum reel be rolled into by rectangle mesh sheet, and rectangle net length of a film is 2000mm, and wide is 900mm;

Rectangle mesh sheet wire diameter on long side direction becomes large gradually, according to spiral of Archimedes, rectangle mesh sheet is rolled into seven layers, outer three layers is outer ring and the wire diameter of outer ring is 0.5mm ~ 0.7mm, middle two-layer for inner ring and the wire diameter of inner ring is 0.7 ~ 0.9mm, the inside two-layer centered by circle and the wire diameter of central ring is 0.9 ~ 1mm;

Rectangle mesh sheet is the outer titanizing layer of copper network, and the thickness of titanium layer is 1 ~ 3 micron.

Further, the Faradaic current of described electrolysis cathode is small area analysis, and size of current is 0.3 ~ 0.6A, and voltage is 1 ~ 1.5V.

The utility model has the advantage of: 1. the utility model effectively removes the foreign metal ion of electroplate liquid by the electrolysis cathode in molten zinc groove, the plating solution of guarantee pure.

2. electrolysis cathode of the present utility model is oval net-shaped drum and peripheral sky greatly can more effective removal noble potential impurity, centre circle can remove the metal ions such as galvanized iron, inner ring removes cupric ion, classification of impurities is removed like this, makes deimpurity process more effective.

3. the electrical current of electrolysis cathode of the present utility model is small area analysis, can carry out the removing of impurity like this when not affecting plating.
