Description
Technical field
The present invention relates to a kind of alkaline zinc plating electroplating pool, especially a kind of alkaline zinc plating high-purity electroplate liquid electroplating pool.
Background technology
Electrogalvanizing is also named cold galvanizing, is that workpiece is placed in to electrolyte, is that plated metal is separated out and is deposited on workpiece and formsCoating, its coating is compared with galvanizing ratio, thinner, is generally 4-12 micron, and the quality of coating is most important link, what electroplateIn process, due to speed, the factor such as the dispersibility of CURRENT DISTRIBUTION inequality, electroplating solution is not strong, can cause a goods positionThickness of coating inequality, and the corrosion resistance of coating depends primarily on thickness of coating and exposed environments, service condition is more severeThe coating needing is thicker, and the corrosion resistance of whole coating depends on that the weakest part of coating comprises local thickness's minimumLocal resistance to corrosion, general present situation, adds thickness coating in order to obtain better corrosion resistance, undoubtedly in increased cost andThe waste of zinc metal, and coating is thicker, the internal stress of coating is larger, and coating easily comes off, and also easily produces coarsely, the flaw such as burnsDefect, and the excessively thin place of coating, low in glossiness, obfuscation, a mist, easily show-through in the process of bright dipping and passivation. No matter from anti-Corrosivity, or outward appearance, the aspects such as machinability, all wish to reduce the uniformity of the thickness that improves the each position of product coatingExtreme difference.
Tradition alkaline zinc plating directly adopts zine plate as anode, and when anode quantity is very few, easily passivation is not dissolved, anode quantityToo much time, can cause zinc concentration in solution to raise, and after anodic solution shortens, can affect electric conductivity, these all can affect platingThe stability of liquid, and due to the impact of time, have many foreign ions and produce, such as metal ions such as cadmium, lead, copper, iron,Time is longer, and the concentration of foreign ion is just higher, and then affects product quality. Therefore just must develop one and can remove electricityIn plating solution, foreign ion keeps the highly purified electroplating pool of electroplate liquid, does not find and the same or analogous device of the present invention through retrieval.
Summary of the invention
The technical problem to be solved in the present invention is to provide one and can removes in electroplate liquid foreign ion and keep electroplate liquid highThe electroplating pool of purity.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of alkaline zinc plating high-purity electroplate liquid electroplating pool,Comprise an electroplating bath, electroplating bath comprises electroplates major trough and a molten zinc groove being connected with plating major trough by filter, in electroplating bathOn wall, be provided with at least one positive plate, directly over molten zinc groove, a telescopic bar be set, telescopic bar bottom arranges one notDissolubility hanging basket, is provided with zinc ball in hanging basket, its innovative point is: on molten zinc groove sidewall, at least one electrolysis cathode is set; Described electricitySeparating negative electrode is a helical form reel being rolled into by rectangle net sheet, and rectangle net length of a film is 2000mm, and wide is 900mm;
Rectangle net sheet wire diameter on long side direction becomes greatly gradually, according to spiral of Archimedes, rectangle net sheet is rolled into sevenLayer, outer three layers are outer ring and outer ring wire diameter is 0.5mm ~ 0.7mm, the middle two-layer wire diameter for inner ring and inner ring is 0.7 ~0.9mm, the inside two-layer centered by the wire diameter of circle and central ring be 0.9 ~ 1mm;
Rectangle net 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 little electric current, and size of current is 0.3 ~ 0.6A, voltage is 1 ~1.5V。
The invention has the advantages that: 1. the present invention effectively removes electroplate liquid by electrolysis cathode in molten zinc grooveForeign metal ion, the plating solution of guarantee pure.
2. electrolysis cathode of the present invention is that oval net-shaped drum and peripheral sky can be mixed by more effective removal high potential greatlyMatter, centre circle can be removed the metal ions such as galvanized iron, and inner ring is removed copper ion, like this classification of impurities is removed, and makes deimpurityProcess is more effective.
3. the electrical current of electrolysis cathode of the present invention is little electric current, can in the situation that not affecting plating, carry out like thisThe removing of impurity.
