のである。Detailed Description of the Invention (a) Technical field The present invention provides a cathode plate used for electrolytic refining of metals, in which the electrodeposit can be easily removed by preventing the electrodeposit from connecting on the front and back surfaces of the cathode plate. The present invention relates to a method of insulating and covering the peripheral edge of the plate surface of an electrode plate with a band-shaped insulating material in order to achieve this.

）。(b) Prior art Conventionally, in order to facilitate the removal of electrodeposit from the cathode plate, band-shaped insulators made of rubber or plastic and having a U-shaped cross section were installed on both left and right edges of the cathode plate, and in some cases also on the lower edge. A commonly used method is to fit and hold objects (see Figure 1).

陰極板に絶縁部を形成する方法も行なわれている。Furthermore, there is a method of fixing these insulators to the cathode plate using an adhesive that is compatible with the usage conditions of the cathode plate, or a method of drilling a plurality of through holes in advance at appropriate positions on the periphery of the cathode plate and using polyethylene, etc. After fitting a plastic band-shaped molded product with a U-shaped cross section to the peripheral edge of the cathode plate, heat and pressurize it by appropriate means to partially cut the front and back of the cathode plate through the perforated part. Weld the plastic plates together,
Another method is to form an insulating part on the cathode plate.

、陰極板本体の寿命が陰極板周縁部の寿命に限定されて
しまい、これが大きな欠点となっていた。However, the first method using fitting and clamping does not prevent damage to the cathode plate body at the peripheral edge of the cathode plate due to age-related deterioration of the material used as the insulator or electrolyte permeating into the gap between the insulator and the cathode plate. Due to wear and tear over time due to preferential corrosion, the gripping force of the insulator strip on the cathode plate gradually decreases, and the insulator strip may fall off from the cathode plate due to external force when the cathode plate comes into contact with other equipment during handling. Not only does this occur frequently, impeding smooth operation, but the lifespan of the cathode plate itself is limited to that of the periphery of the cathode plate, which is a major drawback.

施しなければならない面倒があった。Next, the method using the second adhesive involves adhering dissimilar materials, ie, metal and rubber or metal and plastic, so it is relatively difficult to adhere to the cathode plate in terms of adhesive strength and deterioration of the adhesive itself over time. In addition to being extremely difficult to find a combination that satisfies the usage conditions, there is also the hassle of having to properly pre-treat both the insulator and the cathode plate before bonding.

り、改善すべきところが多い。In addition, in the 7iTj3 plastic heat welding method, in order to compensate for the major drawback that the welding strength between metal and plastic is insufficient, a plurality of holes are formed at appropriate positions on the periphery of the cathode plate to which the strip-shaped plastic insulator is attached as described above. The method used is to drill a hole and partially weld the plastic pieces together through this hole, but this is not a reliable method as a whole, and the hole machining is time-consuming, and there are many improvements that need to be made.

The present invention proposes a simple method that provides sufficient welding strength without requiring processing and that does not fall off during handling.

としてしばしば用いられて来た。Among plastics, polyolefin-based polyethylene, polypropylene, etc. have sufficient material properties such as heat resistance, chemical stability, and electrical insulation under the conditions of use of cathode plates in general aqueous electrolytic refining. Because of its relatively good cost performance, it has often been used as an insulating material for the peripheral edge of the cathode plate.

最適なものといえる。However, it has disadvantages in terms of processing, such as high melt viscosity and poor fluidity due to its unusually large average molecular weight, and although the material itself is relatively cheap among engineering plastics, it is difficult to bond. In addition, ultra-high molecular weight polyethylene has other properties that conventional polyethylene has, such as weather resistance, water resistance, 'Fj, and air properties. With the exception of the difficulty of the process, its material properties can be said to be optimal as an insulating material for the peripheral edge of the cathode plate.
本発明者等は、ポリオレフィン系プラスチック、好まし

に目を向け、鋭意調査、研究。The present inventors focused on these excellent material properties of polyolefin plastics, preferably ultra-high molecular weight polyethylene, and conducted extensive investigation and research.
試験を重ねた結果、本発明に至ったものである。As a result of repeated tests, we have arrived at the present invention.

して該絶縁物を陰極板に強固に溶着するものである。In the present invention, a polyolefin plastic with a high average molecular weight, preferably ultra-high molecular weight polyethylene, is used as the insulating material for the peripheral edge of the cathode plate, and this is fixed to the peripheral edge of the negative electrode plate. A sheet of polyolefin plastic with a lower average hardness than the insulator is sandwiched between the insulator and the cathode plate, and a suitable material is used to firmly hold the sheet and the insulator around the periphery of the cathode plate. A simple method is to press the sheet uniformly with a jig and hold it in a uniform heating furnace for an appropriate period of time at a temperature at which the middle sheet softens and melts, and at which the outer insulator maintains its shape. The insulator is firmly welded to the cathode plate via the softened and melted intermediate sheet.
しかも、この溶着強度は陰極板の使用条件において充分
なものであるので、陰極板の使用期間中はとんど剥離す
ることがない。Furthermore, since this welding strength is sufficient under the conditions in which the cathode plate is used, the cathode plate hardly peels off during its use.

There is no need to be particularly careful like when fishing, just degreasing and polishing is sufficient.

It was kept at ±10°C for about 1 hour.
その結果、炉から取り出した絶縁物２は、軟化溶融した
中間シート３を介して陰極板ｌに強固に溶着していた。As a result, the insulator 2 taken out from the furnace was firmly welded to the cathode plate 1 via the softened and melted intermediate sheet 3.

、絶縁物および陰極板双方の寿命の延長が図られた。When the cathode plate l manufactured in this way was applied to zinc electrowinning field operations, there were no problems at all, and compared to the conventionally used insulator made of rubber inserts, it has particularly good wear resistance and durability. Combined with the material's chemical properties, the life expectancy of both the insulator and cathode plate was extended.

なった。Furthermore, the phenomenon of the band-shaped insulator 2 falling off the cathode plate during operation was eliminated, and smooth operation became possible. Another advantage of using ultra-high molecular weight polyethylene is that there is no need to be particularly careful about abrasion of the insulation when polishing the cathode plate with a wire brush, etc., and when removing electrodeposit from the cathode plate, the insulation is removed. Since the stripping knife slides smoothly on the handle, the insulator is not damaged by the knife, and the insulator is no longer damaged by contact with other equipment during handling.

This can be fixed securely and firmly using a simple method, extending the life of both the insulator and the cathode plate to the same level as the life of the cathode plate due to wear and tear over time, and the material cost is low. It has advantages such as easy operation management.
