Description

本発明は、化学工業分野に関し、具体的に、電解陰極アセンブリ及び電解槽に関する。   The present invention relates to the chemical industry field, and more particularly, to an electrolytic cathode assembly and an electrolytic cell.

湿式電解亜鉛プロセスにおいて、電解槽内で電解液の液位が変動するから、亜鉛シートの上部位に、不定形の波形形状の斜面が形成し、亜鉛剥離用刃物は、亜鉛シートと陰極板との間に挿入しにくく、亜鉛シートの剥離に不利になり、このため、近代化された電解亜鉛分野では、電解亜鉛陰極に仮剥離口を設置することが多い。   In the wet electrolytic zinc process, since the liquid level of the electrolytic solution fluctuates in the electrolytic cell, an irregular corrugated slope is formed on the upper part of the zinc sheet, and the zinc peeling blade is composed of a zinc sheet and a cathode plate. Therefore, in the field of modernized electrolytic zinc, a temporary peeling port is often provided at the electrolytic zinc cathode.

現在、最新の技術で、電解亜鉛陰極は、主に電解亜鉛陰極、等長の2本の絶縁エッジクランピングストリップ、及び仮剥離シートからなる。絶縁エッジクランピングストリップは、電解亜鉛陰極の両エッジに熱圧着され、陰極板の水線位置で表裏両面に剥離口沈めテーブルを予め加工し、剥離口に絶縁の仮剥離シートを注湯し、電解した後、剥離口に亜鉛の析出がない、又は析出量が少なく、仮剥離口を形成し、切込み及び剥離を行う。当該構造の欠点は、(1)仮剥離シートと電解亜鉛陰極とが2種類の材料の粘着力により粘着されており、電解動作環境が50℃程度であり、シート剥離時の環境が25℃程度であり、頻繁的な冷熱交互のため、仮剥離シートが緩んだり脱落したり、且つ、槽での強酸により腐食され、電解亜鉛がそのスリットに進入し、シート剥離が困難になること、(2)仮剥離シートが電解亜鉛陰極に固定され、仮剥離シートが緩むため、剥離用刃物がアルミニウム陰極板にあたり、剥離用刃物が損傷しやすいこと、(3)陰極板を加工する必要があり、陰極の製造コストが向上されること、(4)仮剥離シートが損傷した後、置換工程が複雑になることにある。   At present, with the latest technology, the electrolytic zinc cathode mainly consists of an electrolytic zinc cathode, two insulating edge clamping strips of equal length, and a temporary release sheet. The insulating edge clamping strip is thermocompression bonded to both edges of the electrolytic zinc cathode, pre-processed the peeling port sink table on both the front and back surfaces at the water line position of the cathode plate, and poured an insulating temporary peeling sheet into the peeling port, After electrolysis, there is no deposition of zinc at the peeling port or the amount of precipitation is small, and a temporary peeling port is formed, and cutting and peeling are performed. The disadvantages of this structure are: (1) The temporary release sheet and the electrolytic zinc cathode are adhered by the adhesive force of two types of materials, the electrolysis operating environment is about 50 ° C., and the environment at the time of sheet peeling is about 25 ° C. Because of frequent alternating heat and cold, the temporary release sheet loosens or falls off, and is corroded by strong acid in the tank, and electrolytic zinc enters the slit, making it difficult to peel off the sheet (2 ) Since the temporary release sheet is fixed to the electrolytic zinc cathode and the temporary release sheet is loosened, the peeling blade hits the aluminum cathode plate, and the peeling blade is easily damaged. (3) The cathode plate needs to be processed. (4) After the temporary release sheet is damaged, the replacement process becomes complicated.

このように、従来の電解亜鉛陰極には、改善の余地があった。   Thus, the conventional electrolytic zinc cathode has room for improvement.

本発明は、従来技術における少なくとも一つの技術的課題を解決することを目的とする。そのため、本発明の一つの目的は、簡単で信頼的な手段で陰極板に仮剥離口を形成し、陰極板を改造する必要がなく、置換しやすい電解陰極アセンブリを提供することにある。   An object of the present invention is to solve at least one technical problem in the prior art. Therefore, an object of the present invention is to provide an electrolytic cathode assembly that is easy to replace without forming a temporary peeling port in the cathode plate by a simple and reliable means, without requiring modification of the cathode plate.

そのため、本発明の一形態によれば、本発明は、電解陰極アセンブリを提供する。本発明の実施例によれば、当該電解陰極アセンブリは、陰極板、前記陰極板の側辺に封止されるエッジストリップ(edge-covering strip)、及び、一方のエッジストリップの上に位置するとともに、前記陰極板にシールされ挟持される絶縁クランプを含む。   Thus, according to one aspect of the present invention, the present invention provides an electrolytic cathode assembly. According to an embodiment of the present invention, the electrolytic cathode assembly is positioned on a cathode plate, an edge-covering strip sealed to a side of the cathode plate, and one edge strip. And an insulating clamp sealed and clamped by the cathode plate.

本発明の実施例に係る電解陰極アセンブリによれば、絶縁クランプが陰極板に挟持されることにより、当該挟持部位をシールし、電解陰極アセンブリが槽体で電解する場合に、電解液が絶縁クランプ内部に進入することがなく、電解金属が陰極を被覆することを防止する。電解金属を剥離する時、外力をかけて絶縁治具を搬出し、電解金属が絶縁治具のヘッドに仮剥離口を形成し、剥離用刃物の切込みが便利になる。絶縁クランプは、高耐久性の締付力を有するため、陰極板の挟持部位をシールし、電解金属が陰極を被覆することを効果的に防止するとともに、絶縁クランプと陰極板とが分離可能であり、置換が容易になり、また、従来の陰極板の構造を変える必要がなく、陰極板の機械的加工が不要となり、生産工程を簡単化し、コストを節約する。   According to the electrolytic cathode assembly according to the embodiment of the present invention, when the insulating clamp is clamped by the cathode plate, the sandwiched portion is sealed, and when the electrolytic cathode assembly is electrolyzed by the tank body, the electrolytic solution is insulated clamp. It does not enter the inside and prevents the electrolytic metal from covering the cathode. When peeling the electrolytic metal, an external force is applied to carry out the insulating jig, and the electrolytic metal forms a temporary peeling port in the head of the insulating jig, so that it is convenient to cut the peeling blade. The insulation clamp has a highly durable clamping force, so that the clamping part of the cathode plate is sealed to effectively prevent the electrolytic metal from covering the cathode, and the insulation clamp and the cathode plate can be separated. In addition, the replacement becomes easy, the structure of the conventional cathode plate does not need to be changed, the mechanical processing of the cathode plate becomes unnecessary, the production process is simplified, and the cost is saved.

The clamping end can be opened around the connection end. Thereby, the insulation clamp has a highly durable clamping force effectively and has a good sealing effect.

本発明の実施例によれば、前記絶縁クランプの長さが5mmより大きく、100mm未満である。これにより、形成された剥離口の大きさが適合である。   According to an embodiment of the present invention, the length of the insulating clamp is greater than 5 mm and less than 100 mm. Thereby, the size of the formed peeling opening is suitable.

本発明の実施例によれば、前記挟持端は、弾性絶縁防食材料からなる。これにより、シール効果が良い、使用寿命が長い。   According to an embodiment of the present invention, the clamping end is made of an elastic insulating and anticorrosive material. Thereby, the sealing effect is good and the service life is long.

本発明の実施例によれば、前記絶縁クランプの下に位置する前記エッジストリップの長さは、対向側に位置する前記エッジストリップの長さよりも小さい。これにより、電解液における絶縁クランプの位置の調節が便利になる。   According to an embodiment of the present invention, the length of the edge strip located under the insulating clamp is smaller than the length of the edge strip located on the opposite side. This makes it convenient to adjust the position of the insulating clamp in the electrolyte.

本発明の実施例に係る電解槽によれば、電解陰極アセンブリは、絶縁クランプにより陰極板に挟持されることにより、当該挟持部位をシールし、電解陰極アセンブリが槽体で電解する場合に、電解液が絶縁クランプ内部に進入することがなく、電解金属が陰極を被覆することを防止する。電解金属を剥離する時、外力をかけて絶縁治具を搬出し、電解金属が絶縁治具のヘッドに仮剥離口を形成し、剥離用刃物の切込みが便利になる。絶縁クランプは、高耐久性の締付力を有するため、陰極板の挟持部位をシールし、電解金属が陰極を被覆することを効果的に防止するとともに、絶縁クランプと陰極板とを分離でき、置換が容易になり、また、従来の陰極板の構造を変える必要がなく、陰極板の機械的加工が不要となり、生産工程を簡単化し、コストを節約する。   According to the electrolytic cell according to the embodiment of the present invention, the electrolytic cathode assembly is clamped to the cathode plate by the insulating clamp to seal the sandwiched portion, and the electrolytic cathode assembly is electrolyzed when the electrolytic cathode assembly is electrolyzed by the tank body. The liquid does not enter the inside of the insulating clamp and prevents the electrolytic metal from covering the cathode. When peeling the electrolytic metal, an external force is applied to carry out the insulating jig, and the electrolytic metal forms a temporary peeling port in the head of the insulating jig, so that it is convenient to cut the peeling blade.

本発明の一形態によれば、本発明は、電解陰極アセンブリを提供する。図1を参照し、本発明の実施例によれば、当該電解陰極アセンブリを説明し、当該電解陰極アセンブリ100は、陰極板10、エッジストリップ20、及び絶縁クランプ30を含む。本発明の実施例によれば、エッジストリップ20が陰極板10の側辺に封止される。図2は、電解陰極アセンブリのA−A断面の部分模式図を示し、図2を参照し、本発明の実施例によれば、絶縁クランプ30は、一方のエッジストリップ20の上に位置し、陰極板20上にシールされ挟持され、槽体において、電解陰極アセンブリが電解する場合に、電解液が絶縁クランプ内部に進入することがなく、電解金属が陰極を被覆することを防止する。電解金属を剥離する時、外力をかけて絶縁治具を搬出し、電解金属が絶縁治具のヘッドに仮剥離口を形成し、剥離用刃物の切込み、剥離が便利になる。   According to one aspect of the present invention, the present invention provides an electrolytic cathode assembly. Referring to FIG. 1, according to an embodiment of the present invention, the electrolytic cathode assembly will be described. The electrolytic cathode assembly 100 includes a cathode plate 10, an edge strip 20, and an insulating clamp 30. According to the embodiment of the present invention, the edge strip 20 is sealed to the side of the cathode plate 10. FIG. 2 shows a partial schematic diagram of an AA cross-section of the electrolytic cathode assembly, and referring to FIG. 2, according to an embodiment of the present invention, the insulating clamp 30 is located on one edge strip 20, When the electrolytic cathode assembly is electrolyzed in the tank body while being sealed and sandwiched on the cathode plate 20, the electrolytic solution does not enter the inside of the insulating clamp and prevents the electrolytic metal from covering the cathode. When the electrolytic metal is peeled off, an external force is applied to carry out the insulating jig, and the electrolytic metal forms a temporary peeling port in the head of the insulating jig, so that it is convenient to cut and peel the peeling tool.

本発明の実施例に係る電解陰極アセンブリによれば、絶縁クランプは、高耐久性の締付力を有し、陰極板の挟持部位をシールし、電解金属が陰極を被覆することを効果的に防止するとともに、絶縁クランプと陰極板とを分離でき、置換が容易になり、また、従来の陰極板の構造を変える必要がなく、陰極板の機械的加工が不要となり、生産工程を簡単化し、コストを節約する。   According to the electrolytic cathode assembly according to the embodiment of the present invention, the insulating clamp has a highly durable clamping force, seals the sandwiched portion of the cathode plate, and effectively prevents the electrolytic metal from covering the cathode. In addition to preventing the insulation clamp and the cathode plate can be separated, replacement is easy, no need to change the structure of the conventional cathode plate, no mechanical processing of the cathode plate is required, simplifying the production process, Save costs.

図3を参照し、本発明の実施例によれば、絶縁クランプ30は、H型を呈し、挟持端31、接続端32及び制御端33を有し、接続端32は、挟持端31及び制御端33を接続するためのものであり、且つ、挟持端31は、接続端32回りに開放可能である。これにより、絶縁クランプの挟持端が陰極板に挟持され、電解液が絶縁クランプの内部に進入することを回避し、電解金属が陰極を被覆することを防止する。制御端は、挟持端の開口の大きさ及び挟持端による挟持の緊密度合いを制御し、絶縁クランプが効果的に高耐久性の挟持力を有することを保証し、絶縁クランプの挟持部位が良好なシール効果を有するようにし、電解液の進入を回避し、電解金属が当該部位の陰極板を被覆することを防止することにより、剥離口を形成し、陰極板上に覆われた電解金属を剥離しやすくなる。   Referring to FIG. 3, according to the embodiment of the present invention, the insulation clamp 30 has an H shape and has a clamping end 31, a connection end 32, and a control end 33, and the connection end 32 includes the clamping end 31 and the control end. The end 33 is for connecting, and the clamping end 31 can be opened around the connection end 32. As a result, the sandwiching end of the insulating clamp is sandwiched between the cathode plates, the electrolyte solution is prevented from entering the interior of the insulating clamp, and the electrolytic metal is prevented from covering the cathode. The control end controls the size of the opening of the clamping end and the tightness of clamping by the clamping end, guarantees that the insulation clamp has a highly durable clamping force, and the insulation clamp has a good clamping part It has a sealing effect, prevents the ingress of electrolyte, prevents the electrolytic metal from covering the cathode plate of the relevant part, forms a separation port, and peels the electrolytic metal covered on the cathode plate It becomes easy to do.

本発明の実施例によれば、絶縁クランプの大きさは、陰極板の大きさに応じて調節ことができ、絶縁クランプによって挟持され形成された剥離口の大きさについて、剥離が容易であれば良い。本発明の一部の実施例によれば、絶縁クランプ30の長さが5mmより大きく、100mm未満である。これにより、絶縁クランプによって形成された剥離口の大きさが適合であり、電解金属の剥離が容易になる。絶縁クランプが小さすぎると、形成された剥離口が小さすぎ、剥離が困難になる。絶縁クランプが大きすぎると、形成された剥離口が大きすぎ、電解効率が低減されるだけではなく、絶縁クランプが大きすぎ、電解槽の他の部材の設置にも影響を与える。   According to the embodiment of the present invention, the size of the insulating clamp can be adjusted according to the size of the cathode plate, and the size of the peeling port sandwiched and formed by the insulating clamp can be easily peeled off. good. According to some embodiments of the present invention, the length of the insulating clamp 30 is greater than 5 mm and less than 100 mm. Thereby, the magnitude | size of the peeling opening formed by the insulation clamp is suitable, and peeling of an electrolytic metal becomes easy. If the insulating clamp is too small, the formed peeling opening is too small, and peeling becomes difficult. If the insulation clamp is too large, not only is the formed separation opening too large, the electrolysis efficiency is reduced, but the insulation clamp is too large, which affects the installation of other members of the electrolytic cell.

本発明の実施例によれば、挟持端31は、弾性絶縁防食材料からなる。弾性材料の形状が調整しやすいため、絶縁クランプの挟持端を陰極板上に挟持するとともに、電解が終了した後、絶縁クランプを陰極板から取り外すことが便利になる。且つ、絶縁クランプの挟持端は、弾性を有し、絶縁クランプを再利用でき、電解コストを低減する。また、絶縁クランプの防食効果が良く、電解液の絶縁クランプへの腐食作用を軽減又は回避し、絶縁クランプの使用寿命を延長する。   According to the embodiment of the present invention, the clamping end 31 is made of an elastic insulating and anticorrosive material. Since the shape of the elastic material is easy to adjust, it is convenient to hold the holding end of the insulating clamp on the cathode plate and to remove the insulating clamp from the cathode plate after the electrolysis is completed. In addition, the sandwiching end of the insulating clamp has elasticity, and the insulating clamp can be reused, thereby reducing the electrolysis cost. In addition, the anticorrosion effect of the insulating clamp is good, reducing or avoiding the corrosive action of the electrolyte on the insulating clamp, and extending the service life of the insulating clamp.

本発明の一部の実施例によれば、絶縁クランプ30は、弾性絶縁防食材料から一体化成型されても良い。これにより、絶縁クランプを生産しやすく、また、絶縁クランプがより強固で耐久性が高く、破損しにくい。   According to some embodiments of the present invention, the insulating clamp 30 may be integrally molded from an elastic insulating and anticorrosive material. As a result, it is easy to produce an insulating clamp, and the insulating clamp is stronger, more durable, and less likely to break.

本発明の実施例によれば、絶縁クランプ30の下に位置するエッジストリップ20の長さは、対向側に位置するエッジストリップ20の長さよりも短い。金属層が陰極板の表面に吸着されるため、金属層のエッジは、陰極板との密着度が高く、且つ切込みが困難であり、剥離しにくいである。絶縁クランプの位置が切込みの位置であり、絶縁クランプが金属層のエッジラインに位置し、即ち、エッジラインが絶縁クランプの上下エッジの間に位置する場合に、金属層の斜め上から切込みを行うことができ、力学的に、当該角度の支点位置がよく、レバーの付勢力が大きく、金属層を剥離しやすい。電解の過程で、電解液の液面の高さによって、金属層の位置を決定し、絶縁クランプ下に位置するエッジストリップの長さは、対向側に位置するエッジストリップの長さよりも小さいと、電解液の液面がちょうど絶縁クランプの上下エッジの間に位置し、切込みの位置が金属層の斜め上であることを保証し、金属層を剥離しやすくなる。   According to the embodiment of the present invention, the length of the edge strip 20 located under the insulating clamp 30 is shorter than the length of the edge strip 20 located on the opposite side. Since the metal layer is adsorbed on the surface of the cathode plate, the edge of the metal layer has high adhesion to the cathode plate, is difficult to cut, and is difficult to peel off. When the position of the insulating clamp is the cutting position, and the insulating clamp is positioned at the edge line of the metal layer, that is, when the edge line is positioned between the upper and lower edges of the insulating clamp, the cutting is performed from obliquely above the metal layer The fulcrum position of the angle is good mechanically, the biasing force of the lever is large, and the metal layer is easily peeled off. In the process of electrolysis, the position of the metal layer is determined by the height of the electrolyte surface, and when the length of the edge strip located under the insulating clamp is smaller than the length of the edge strip located on the opposite side, The liquid level of the electrolytic solution is located just between the upper and lower edges of the insulating clamp, and it is ensured that the position of the cut is obliquely above the metal layer, so that the metal layer can be easily peeled off.

本発明の他の形態によれば、本発明は、電解槽を提供する。図4を参照し、本発明の実施例によれば、電解槽を説明し、当該電解槽1000は、槽体200、電解陽極アセンブリ300、上述した電解陰極アセンブリ100及び電源400を含む。本発明の実施例によれば、槽体200には、電解液収容空間を有し、電解陽極アセンブリ300と電解陰極アセンブリ100とは、電解液に設置され、電源400は、電解陽極アセンブリ300と電解陰極アセンブリ100とにそれぞれ接続された。   According to another aspect of the present invention, the present invention provides an electrolytic cell. Referring to FIG. 4, according to an embodiment of the present invention, an electrolytic cell will be described. The electrolytic cell 1000 includes a cell body 200, an electrolytic anode assembly 300, the above-described electrolytic cathode assembly 100, and a power source 400. According to the embodiment of the present invention, the tank body 200 has an electrolytic solution housing space, the electrolytic anode assembly 300 and the electrolytic cathode assembly 100 are installed in the electrolytic solution, and the power source 400 is connected to the electrolytic anode assembly 300. Each was connected to the electrolytic cathode assembly 100.

本発明の実施例に係る電解槽によれば、電解陰極アセンブリは、絶縁クランプにより陰極板に挟持されることにより、当該挟持部位をシールし、槽体において電解陰極アセンブリが電解する場合に、電解液が絶縁クランプ内部に進入することがなく、電解金属が陰極を被覆することを防止する。電解金属を剥離する時、外力をかけて絶縁治具を搬出し、電解金属が絶縁治具のヘッドに仮剥離口を形成し、剥離用刃物の切込みが便利になる。絶縁クランプは、高耐久性の締付力を有するため、陰極板の挟持部位をシールし、電解金属が陰極を被覆することを効果的に防止するとともに、絶縁クランプと陰極板とを分離でき、置換が容易になり、また、従来の陰極板の構造を変える必要がなく、陰極板の機械的加工が不要となり、生産工程を簡単化し、コストを節約する。   According to the electrolytic cell according to the embodiment of the present invention, the electrolytic cathode assembly is clamped to the cathode plate by the insulating clamp to seal the sandwiched portion, and the electrolytic cathode assembly is electrolyzed when the electrolytic cathode assembly is electrolyzed in the tank body. The liquid does not enter the inside of the insulating clamp and prevents the electrolytic metal from covering the cathode. When peeling the electrolytic metal, an external force is applied to carry out the insulating jig, and the electrolytic metal forms a temporary peeling port in the head of the insulating jig, so that it is convenient to cut the peeling blade. Since the insulating clamp has a highly durable clamping force, it seals the sandwiched portion of the cathode plate, effectively prevents the electrolytic metal from covering the cathode, and can separate the insulating clamp from the cathode plate. Replacement is facilitated, and there is no need to change the structure of the conventional cathode plate, and mechanical processing of the cathode plate is not necessary, simplifying the production process and saving costs.

本発明の実施例によれば、陰極板10両側の2本のエッジストリップ20の底辺は、いずれも陰極板10の底辺に封止され、絶縁クランプ30下にあるエッジストリップ20の先端は、電解液の液面下に位置し、他方のエッジストリップ20の先端は、電解液の液面上に位置する。上述のように、金属層が陰極板の表面に吸着されるため、金属層のエッジは、陰極板との密着度が高く、且つ切込みが困難であり、剥離しにくいである。絶縁クランプの位置が切込みの位置であり、絶縁クランプが金属層のエッジラインに位置し、即ち、エッジラインが絶縁クランプの上下エッジの間に位置する場合に、金属層の斜め上から切込みを行うことができ、力学的に、当該角度の支点位置がよく、レバーの付勢力が大きく、金属層を剥離しやすい。電解の過程で、電解液の液面の高さによって、金属層の位置を決定し、絶縁クランプ下に位置するエッジストリップの先端は、電解液の液面下に位置し、他方のエッジストリップは、電解液の液面上に位置し、電解液の液面がちょうど絶縁クランプの上下エッジの間に位置し、切込みの位置が金属層の斜め上であることを保証し、金属層を剥離しやすくなる。   According to the embodiment of the present invention, the bottoms of the two edge strips 20 on both sides of the cathode plate 10 are both sealed to the bottom of the cathode plate 10, and the tip of the edge strip 20 under the insulating clamp 30 is electrolyzed. The tip of the other edge strip 20 is located above the liquid surface of the electrolyte. As described above, since the metal layer is adsorbed on the surface of the cathode plate, the edge of the metal layer has high adhesion to the cathode plate, is difficult to cut, and is difficult to peel off. When the position of the insulating clamp is the cutting position, and the insulating clamp is positioned at the edge line of the metal layer, that is, when the edge line is positioned between the upper and lower edges of the insulating clamp, the cutting is performed from obliquely above the metal layer The fulcrum position of the angle is good mechanically, the biasing force of the lever is large, and the metal layer is easily peeled off. In the process of electrolysis, the position of the metal layer is determined by the height of the electrolyte surface, the tip of the edge strip located under the insulation clamp is located below the electrolyte surface, and the other edge strip is , Located on the electrolyte level, ensure that the electrolyte level is just between the upper and lower edges of the insulation clamp, and that the incision is diagonally above the metal layer, peeling off the metal layer It becomes easy.

本発明の実施例によれば、電解液の液面は、絶縁クランプの下端からの1/4〜2/3に位置する。電解液の液面が変動するため、液面線が常に傾け、ひいては、金属層のエッジも傾け、電解液の液面は、絶縁クランプの下端からの1/4〜2/3に位置し、金属層の高さが絶縁クランプの上端よりも低いことを保証する。   According to the embodiment of the present invention, the liquid level of the electrolytic solution is located at 1/4 to 2/3 from the lower end of the insulating clamp. Since the liquid level of the electrolytic solution fluctuates, the liquid level line always inclines, and therefore the edge of the metal layer also inclines, and the electrolytic liquid level is located at 1/4 to 2/3 from the lower end of the insulating clamp, Ensure that the height of the metal layer is lower than the top of the insulating clamp.

本発明の好ましい実施例によれば、電解液の液面は、絶縁クランプの下端からの1/3〜1/2に位置する。発明者は、検討した上で、切込み角度が水平に対して30〜60°になる場合に、剥離刀と陰極板との接触点である支点位置がより良好であり、レバーの付勢力がより大きく、金属層を剥離しにくいことを見出した。また、発明者は、実験と分析計算により、電解液の液面が絶縁クランプの下端からの1/3〜1/2に位置する場合に、絶縁クランプにより金属層に形成された剥離口の鉛直高さが適合であり、切込み角度が水平に対して30〜60°になり、金属層をさらに剥離しにくくなり、且つ剥離された金属層がより完全になることを見出した。   According to a preferred embodiment of the present invention, the liquid level of the electrolyte is located 1/3 to 1/2 from the lower end of the insulating clamp. The inventor has examined, and when the cutting angle is 30 to 60 ° with respect to the horizontal, the fulcrum position that is the contact point between the peeling blade and the cathode plate is better, and the biasing force of the lever is more It was found that the metal layer was large and difficult to peel off. In addition, the inventor has shown that the vertical of the separation port formed in the metal layer by the insulating clamp when the liquid level of the electrolytic solution is located 1/3 to 1/2 from the lower end of the insulating clamp by experiment and analysis calculation. It has been found that the height is suitable, the cutting angle is 30 to 60 ° with respect to the horizontal, the metal layer becomes more difficult to peel, and the peeled metal layer becomes more complete.
