Abstract
The utility model discloses a kind of electrolytic copper powder negative plate, comprise negative plate body (1), described negative plate body (1) has waterline place (2), described waterline (2) place is provided with insulation compound layer (3).Utility model has structure advantage simple, with low cost, and employing can effectively prevent waterline place from fouling occurring, and prevents negative plate waterline place edge corrosion phenomenon of rupture, not only extends negative plate 2-3 in work-ing life doubly, also reduces the production cost of copper powder.
Description
Technical field
The utility model relates to a kind of negative plate, particularly a kind of electrolytic copper powder negative plate.
Background technology
The production of electrolytic copper powder is put in a cell by copper anode plate and negative plate, adopts copper sulfate electrolyte, pass into direct current, Electrowinning copper powder.In electrolytic process, negative plate is put in the electrolytic solution all the time, its waterline place is easy to incrustation and (namely constantly assembles at the waterline place electrolytic copper powder of negative plate, sclerosis), cause waterline place negative plate thickening, be unfavorable for the powder automatic scraper scraping powder machine, even if with manually scraping powder, cathode plate surface copper powder is also difficult to strike off thoroughly.Negative plate waterline place incrustation is serious, removes difficulty, reduces negative plate and scrape powder effect; In addition easily make negative plate from the fracture of waterline incrustation edge corrosion, thus negative plate is scrapped, add copper powder production cost.
Utility model content
The purpose of this utility model is just to provide a kind of electrolytic copper powder negative plate that can effectively prevent negative plate waterline place from incrustation phenomenon occurring.
The purpose of this utility model is realized by such technical scheme, and a kind of electrolytic copper powder negative plate, comprises negative plate body, and described negative plate body has waterline place, and described waterline place is provided with insulation compound layer.
In order to prevent acid and temperature to the destruction of insulation compound layer, be outside equipped with acid-resistant and heat-resistant mixolimnion at described insulation compound layer.
In order to prevent the too high destruction to insulation compound layer of cathode plate surface temperature, between described insulation compound layer and body, be provided with heat-resistant coating layer.
In order to prevent acid in electrolytic solution to the destruction of insulation compound layer, between described insulation compound layer and acid-resistant and heat-resistant mixolimnion, be provided with acid-resistant layer.
In order to make the cohesiveness between them better, between described acid-resistant and heat-resistant mixolimnion and acid-resistant layer, between acid-resistant layer and insulation compound layer, between insulation compound layer and heat-resistant coating layer, be provided with bed of cloth.
Owing to have employed technique scheme, the utility model has structure advantage simple, with low cost, employing can effectively prevent waterline place from fouling occurring, prevent negative plate waterline place edge corrosion phenomenon of rupture, not only extend negative plate 2-3 in work-ing life doubly, also reduce the production cost of copper powder.
Accompanying drawing explanation
Accompanying drawing of the present utility model is described as follows:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is laminate structure figure of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail; but the utility model is not limited to these embodiments; any improvement or alternative on the present embodiment essence spirit, still belongs to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, a kind of electrolytic copper powder negative plate, comprises negative plate body 1, and described negative plate body 1 has waterline place 2, and described waterline 2 place is provided with insulation compound layer 3.
Further, acid-resistant and heat-resistant mixolimnion 4 is outside equipped with at described insulation compound layer 3.By arranging acid-resistant and heat-resistant mixolimnion 4, acid and temperature effectively can be prevented the destruction of insulation compound layer 3, extend the life-span of insulation compound layer.
Further, between described insulation compound layer 3 and body 1, be provided with heat-resistant coating layer 5, be to prevent the temperature of cathode plate surface too high like this, and insulation compound layer 3 is damaged.
Further, between described insulation compound layer 3 and acid-resistant and heat-resistant mixolimnion 4, be provided with acid-resistant layer 6, this is done to prevent acid in electrolytic solution to the destruction of insulation compound layer 3.
Further, between described acid-resistant and heat-resistant mixolimnion 4 and acid-resistant layer 6, between acid-resistant layer 6 and insulation compound layer 3, between insulation compound layer 3 and heat-resistant coating layer 5, be provided with bed of cloth 7, bondd between each layer by bed of cloth 7, make the adhesive property of each layer better, and improve intensity and the toughness of each dope layer, prevent breaking of dope layer, extend work-ing life.
