Description
Technical field
The invention belongs to field of metallurgy more particularly to a kind of pole plate of cathode copper and preparation method thereof.
Background technique
In the cathode copper field of non-ferrous metallurgy, cathode plate, anode plate are staggered relatively in electrolytic bath, anode plate
Copper is gradually dissolved into electrolyte, the copper in electrolyte gradually electrodeposition on cathode plate.Common cathode plate be generally copper sheet or
Stainless steel plate.
In the side edge of cathode plate, can generally be provided with " band tensioning rod type " insulator seal edge strip, by sealed insulation contained side and
It is tensioned stick composition, sealed insulation contained side side is equipped with the U-lag for being used to clamp pole plate, and the other side is equipped with for assembling tensioning stick
Arc-shaped slot, U-lag are dimensioned slightly smaller than the thickness of pole plate, and arc-shaped slot and round tensioning stick are fitted close, in the work of tensioning stick
Under, sealing edge is made to clamp pole plate, insulated enclosure item is made using polyethylene or polypropylene material.Due to electrolyte in electrolytic cell
Temperature is higher, exists in electrolyte in addition and contains transition metal element, so that degradation process accelerates, insulating blanked clamper edge strip is easy to aging,
Service life is generally at 3 months or so.And polyethylene, polypropylene material have creep properties, and it is especially higher in electrolyte temperature
When, it is more easier creep occur, so that not clamping phenomenon occurs in the insulating blanked clamper edge strip of above structure.In addition, above-mentioned close
Seal structure is complicated, and when processing will also individually produce tensioning stick, increases process, improves cost, sealing strip only passes through machinery
Power clamps pole plate, and stability is not strong.
In addition, now commonly used insulator seal edge strip, shape is gentle slope type, and during cathode copper, copper can be gradually
Climb along insulator seal edge strip, or in insulator seal edge strip in dotted, lamellar growth (being commonly called as long nail cover)." climbing " or " long
Nail cover " is in use for some time, impurity to be infected on edge strip, the copper of electrodeposition is gradually since the structure type of edge strip is improper
It is deposited on edge strip, gradually grows up and climb along the flat gradient of edge strip, when degree is serious, the copper of electrodeposition is on edge strip in scattered
The dotted or sheet distribution of column, as the nail cover grown.Climbing, long nail cover cause the copper sheet being electrolysed out or copper sheet edge
It is irregular, the regularity of copper sheet or copper sheet is not only influenced, also difficulty can be caused to subsequent product stripping process, influence finished product
It is packaged work.
Application No. is " a kind of insulation sides and preparation method thereof combined together with pole plate " of " 201310630846.9 " specially
Benefit, by the way that the edge of pole plate to be machined with to evenly distributed hole or slot, after insulating materials is subjected to extrusion molding, passing through extruding machine will
Its insulating materials finally makes insulating materials by pole plate edge tight, is formed smooth through plasticizing, extrusion, sizing cooling treatment
Insulation side, make pole plate with insulation side combine together.This insulation side is single injection-molded, by extruding machine by insulating materials
At the edge of pole plate, insulating materials tight bond has the advantages that acidproof at pole plate edge for direct founding, and is difficult to fall off.
But there are still some shortcomings: 1, in extrusion process, pole plate does even relative to the side mode machine discharge port of extruding machine
Speed linear motion, due to having opened hole with certain thickness pole plate, the insulating materials some of plasticizing is directly fixed in polar board surface
On, what is had will fill the solidification of hole gap, will become insulating materials and the closely sealed bonding of pole plate near pole plate tapping or aperture
Vulnerable area, edge strip bonds insecure with pole plate；2, " climbing " during cathode copper, " long nail cover " phenomenon are difficult to gram
Clothes.
Summary of the invention
The present invention provides a kind of pole plate of cathode copper, including pole plate, edge strip, and the pole plate side edge opens through hole, described
Edge strip insulation, edge strip wrap pole plate side area and hole, and the edge strip cross section is half elliptic.
Pole plate side edge opens through hole, and edge strip is protective layer, and edge strip wraps pole plate side area, and edge strip is through opening
Hole, edge strip wrap pole plate from the side of pole plate to three, front, reverse side directions in pole plate side area, the edge strip of polar plate two-sided,
Edge strip in the lateral edge strip of pole plate, hole forms a closing structure, connect edge strip with pole plate stronger.
Edge strip is insulating materials, non-conductive, and the cross section of edge strip is half elliptic, and the outer edge of edge strip is arc surface, no
Only be conducive to form, moreover it is possible to eliminate stress concentration, the inward flange of edge strip is the abrupt slope perpendicular to pad-face, eliminates cathode copper mistake
" climbing " and " long nail cover " phenomenon in journey.
Further, edge strip is plastics, and edge strip main body is polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), gathers

The one or more of thioether (PPS), polyurethane (PU), epoxy resin.
A kind of mode, the hole that pole plate side is opened, bore dia are 3 millimeters to 10 millimeters.
Bore dia is too small, and processing is inconvenient, and the more difficult complete coating of anti-corrosion insulating layer covers complete hole inner wall surface, holds
Easily there are gaps；Bore dia is excessive, then wastes more materials and be filled into hole, it is not necessary that, it also will cause plate strength
It reduces.
A kind of mode, the hole that pole plate side is opened are 1 row or 2 rows, and bore edges are 3 to 10 millis from pole plate edge minimum range
Rice.
1 row of pole plate side aperture or 2 rows can meet the requirements, number of rows it is more It is not necessary to；Bore edges are apart from pole plate edge
It crosses closely, then the intensity at easy damaged pole plate edge, bore edges too far, then can more reduce the electrodeposition face of pole plate apart from pole plate edge
Product.
