本発明は、 メ ツキ原板に連続的に電解亜鉛メ ツキ、 電 1 メ ツキ等を施す電解メ ツキ装置の主構成要素である電解メ ッ キ用不溶性陽極に関し、 より詳し く は、 陽極板が電極基体に 着脱自在に取付けられている不溶性陽極に関するものである。 The present invention relates to an insoluble anode for electrolytic plating, which is a main component of an electrolytic plating apparatus for continuously applying electrolytic zinc plating, electroplating, and the like to a plating base plate.

背景技術 Background art
従来、 鋼帯等のメ ツキ原板に連続的に電解亜鉛メ ツキ、 電 解錫メ ツキ等を施すには、 不溶性陽極と して、 電極基体の鐧 帯対向面側に電極反応および導電のために鉛または鉛系合金 を肉盛り したものが使用されてきた。 しかし、 この陽極は、 肉盛り部から溶出した鉛によるメ ツキ浴の汚染、 メ ツキ膜質 の低下等の問題があった。 これに代わる陽極と して、 陽極材 上に電極活性物質と して酸化ィ リ ジゥムを含む電極活性被覆 層を有する不溶性陽極が種々提案されている。 Conventionally, in order to continuously apply electrolytic zinc plating, electrolytic tin plating, etc. to a metal plate such as a steel strip, it is necessary to use an insoluble anode as an insoluble anode on the side of the electrode base opposite to the metal plate for electrode reaction and conductivity. In this case, a lead or lead-based alloy is used. However, this anode had problems such as contamination of the plating bath due to lead eluted from the build-up portion and deterioration of the plating film quality. As an alternative to this, various insoluble anodes having an electrode active coating layer containing, as an electrode active material, an electrode active material on an anode material have been proposed.
この種の陽極では、 一般に、 その陽極材上に被着した電極 活性層が、 鉛または鉛系合金を肉盛り した陽極に比べて極め て薄いため、 電気亜鉛メ ツキライ ン等のように錮帯が高速で 陽極近傍を走行する時に、 鋼帯のバタツキにより鋼帯が陽極 に接触し、 陽極表面の電極活性層に局部的な損傷を生じ、 そ の陽極活性が失われることがある。 このような局部失活が原 因で製品にメ ッキむら等を生じ品質低下を招く ため、 陽極の 補修、 交換などが必要となってく る。
実開平 2— 1 3 6 0 5 9号公報には、 陽極の補修を容易に 行うために陽極板を複数個に分割し、 陽極板の分割片を電極 基体に電解面側から導電性ボル トによって着脱自在に取付け られている電解メ ッキ用分割型不溶性陽極が提案されている。 また実開昭 6 3— 1 3 1 7 6 4号公報には、 第 1の電極基体 に、 電極活性物質で被覆された第 2の電極基体が電極活性層 側からチタ ンボル トによつて着脱可能に取付けられている電 解用複合電極が提案されている。 Generally, in this type of anode, the electrode active layer deposited on the anode material is extremely thin compared to the anode coated with lead or a lead-based alloy, and therefore, such as an electro-zinc plating line, etc. When a steel strip runs near the anode at high speed, the steel strip may come into contact with the anode due to flapping of the steel strip, causing local damage to the electrode active layer on the anode surface and losing the anode activity. Such local deactivation causes unevenness in the product and lowers the quality of the product, which necessitates repair and replacement of the anode. Japanese Utility Model Laid-Open No. 2-133659 discloses that the anode plate is divided into a plurality of pieces to facilitate repair of the anode, and the divided pieces of the anode plate are electrically conductively bolted to the electrode substrate from the electrolytic surface side. There has been proposed a split-type insoluble anode for an electro-mechanical, which is removably attached to the electrode. Japanese Utility Model Laid-Open Publication No. 63-131,764 discloses that a second electrode substrate coated with an electrode active material is attached to and detached from the first electrode substrate from the electrode active layer side by using a titanium bolt. A composite electrode for electrolysis that has been mounted as possible has been proposed.
このように、 これらの公報には、 陽極板を電極基体に陽極 板側からボル トによって着脱自在に取付けることが示されて いるが、 そのボル トの取付け位置等については何ら開示がさ れていない。 As described above, these publications indicate that the anode plate is removably attached to the electrode base from the anode plate side by a bolt, but the mounting position of the bolt is not disclosed at all. Absent.
上記公報の記載のように、 陽極板が電極基体に、 電解面側 すなわち電極活性肩側からボル トによって取付けられている 電極では、 その陽極板の交換に要する手間は大幅に減少する が、 そのボル ト取付け孔部は一般に電極活性層で被覆されて おらず、 したがって電流が流れない。 ボル ト取付け孔部を電 極活性層で被覆しても、 取付け工具による電極活性層の損傷 を招いたり、 同部分の特殊な形状のために電極活性層の被覆 には多大な労力を要したりするため、 経済的に不利である。 また、 ボルト取付け孔部を被覆した電極活性層は傷などのた め短時間でこれから剥雠してしまい、 同部分が通電不能とな る。 ポル トの頭部を電極活性層で被覆しても、 ボル ト取付け 孔部の被覆と同様に、 電極活性層の損傷や短い寿命のため通 電不能が起こ る。 このような菲通電部分が局部的に存在する と、 製品にメ ツキむらが生じるなどの外観上の問題を起こす。
本発明の目的は、 鐧帯等のメ ツキ原板に連続的に電解メ ッ キを施す電解メ ツキ装置の不溶性陽極において、 陽極面に形 成されたボル ト頭嵌入用の複数個の凹部によつて局部的な非 通電部が生じるのを回避するこ とができる不溶性陽極を提供 し、 これによつて製品におけるメ ツキむら等の発生を防ぐこ とにある。 発明の開示 As described in the above publication, in an electrode in which the anode plate is attached to the electrode substrate by a bolt from the electrolytic surface side, that is, the electrode active shoulder side, the time required for replacing the anode plate is greatly reduced. The bolt mounting hole is generally not covered with the electrode active layer, and therefore no current flows. Even if the bolt mounting hole is covered with the electrode active layer, the mounting tool may damage the electrode active layer, and the special shape of the part requires a great deal of labor to cover the electrode active layer. Is economically disadvantageous. In addition, the electrode active layer covering the bolt mounting holes is peeled off from the electrode active layer in a short time due to scratches and the like, and the portion cannot be energized. Even if the head of the port is covered with the electrode active layer, as in the case of the bolt mounting hole, the electrode cannot be electrically connected due to damage or short life of the electrode active layer. If such a conductive part is present locally, it causes appearance problems such as unevenness of the product. SUMMARY OF THE INVENTION An object of the present invention is to provide, in an insoluble anode of an electroplating apparatus for continuously electroplating a plating plate such as a belt, a plurality of recesses formed on the anode surface for bolt head fitting. Accordingly, an insoluble anode capable of avoiding the occurrence of a local non-conductive portion is provided, thereby preventing the occurrence of unevenness or the like in a product.
