Description
Technical field
The present invention relates to the hydrometallurgy industry, be specifically related to novel electrolysis, electrodeposition negative plate in a kind of electrolytic copper, electro deposited copper, the electrolytic manganese industry and preparation method thereof.
Background technology
When producing electrolytic copper, electro deposited copper, electrolytic manganese process, all adopt permanent stainless steel cathode plate as negative plate at present, existing technique domestic, domestic employing is divided into following several:
1, ladle copper.Take copper as conducting beam, reach good electroconductibility.Coat 316 stainless steel plates of one deck 2mm in the outside of copper, with rigidity and the protection copper corrosion that reaches conducting beam.The stainless steel that negative plate plate face and conducting beam outside coat welds, and upper method is that domestic enterprise's use is maximum.Its shortcoming is: the not name that conducting beam and stainless steel are laminated with is enough fine and close, and causing easily has the space in bi-material, cause acid mist to enter, and the corrosion conducting beam affects work-ing life, and is laminated with bad meeting and causes conductive effect poor, causes the problems such as electrical efficiency is low.
2, copper-clad stainless steel.Take stainless steel as conducting beam, stainless steel polar plate plate face and stainless steel current conducting rod elder generation welding fabrication, again by negative plate handstand mode is electroplated.About about 2mm, this mode conducts electricity very well electroplating thickness greatly, but its shortcoming is: (1) complex manufacturing technology, cause other pollution easily when cost height and plating.(2) copper of electroplating in the conducting beam outside uses through long-time, by electrolysis acid fog oxidation and corrosion, has reduced work-ing life easily.
3, stainless steel, copper, three layers of iron are compound.Take copper as the middle layer.The copper nexine is the A3 steel.The steel skin is 316 stainless steels.The advantage of this technique is that the price of conducting beam is low, and holistic cost descends, but its shortcoming is the manufacturing process complexity, and three layers must close can be very not fine and close, and the thermal expansivity of trilaminate material is different, can cause electric conductivity to descend, and brings the problems such as production cost increases.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, and a kind of novel electrolysis that has high conductivity, high strength, high corrosion resistant and reach the compactness between bi-material, electrodeposition negative plate and preparation method thereof are provided.
The objective of the invention is to finish by following technical solution, this electrolysis, electrodeposition negative plate mainly are made of stainless steel cathode plate and copper conducting beam, described copper conducting beam offers an elongated slot, stainless steel cathode plate is plugged in the elongated slot of copper conducting beam, and the outside of this copper conducting beam is covered with one deck carbon fibre cloth layer.
As preferably, a kind of aforesaid novel electrolysis, electrodeposition negative plate of utilizing realized its preparation method, and the method comprises following several step:
1), to open an about degree of depth identical with stainless steel cathode plate plate face thickness in the middle of the copper conducting beam be 5 ~ 15mm, width is the elongated slot of 1 ~ 2.5mm;
2), the stainless steel cathode plate insertion has been held successfully in the copper conducting beam of elongated slot;
3), stainless steel cathode plate and copper conducting beam after will installing, carry out again cold rollingly, make its bi-material roll into one, to reach the electroconductibility of superelevation;
4), weld with welding machine in the place of copper conducting beam and stainless steel cathode plate seam;
5) after, welding is finished that weld grinding is even;
6), the negative plate after welding finished puts into molding die, copper conducting beam and copper conducting beam down stainless steel cathode plate plate face 5cm carry out whole carbon fiber reinforce plastic in the place, the thickness of this carbon fibre cloth layer is between 2 ~ 5mm, to reach the intensity of copper conducting beam.
Beneficial effect of the present invention is: overcome the shortcoming when using permanent stainless steel cathode plate in present stage electrolytic copper, electro deposited copper, the electrolytic manganese industry, the external reinforcing material of copper conducting beam is adopted carbon fibre initial rinse fabric or glass fibre preimpregnation cloth and adopts the hot moulding technology to make, the novel cathode plate has high conductivity, high strength, high corrosion resistant and reaches compactness between bi-material, has greatly improved work-ing life.
