Description
本發明是關於一種適用於工作樣品表面或局部表面之電化學處理用模具，此模具可使待處理樣品之特定表面裸露，並使工作樣品在進行電化學加工時保持特定的溫度，此具有冷卻功能的電化學治具可提供需特定裸露之樣品表面進行電解、電解拋光、電鍍、陽極處理、蝕刻、浸鍍、酸洗、鹼洗、等綠能相關產業之製程。 The invention relates to an electrochemical treatment mold suitable for working on a surface or a partial surface of a working sample, which can expose a specific surface of a sample to be treated and maintain a specific temperature of the working sample during electrochemical processing, which has cooling The functional electrochemical fixture can provide processes for the green energy-related industries such as electrolysis, electropolishing, electroplating, anodizing, etching, immersion plating, pickling, caustic washing, etc. on the surface of a specific exposed sample.
學術或研究單位在製作電化學小試片時可簡單地控制所需的實驗條件，但是當樣品尺寸與數量放大至工業界量產時卻常常面臨到電流密度和溫度不穩定的問題。 Academic or research units can simply control the experimental conditions required when making electrochemical small test strips, but often suffer from current density and temperature instability when the sample size and quantity are scaled up to industrial mass production.
一般教科書對於電化學的反應，常以簡單的示意圖解釋之，其中陽極又稱為氧化極，於反應過程中易失去電子、或產生離子化，陰極又稱為還原極，於反應過程中易得到電子或接受正離子，而外加電壓/電流值與電解液的成份、濃度、溫度、與攪伴乃是控制反應速率的重要參數，由於示意圖為一簡便且眾所容易接受之反應機構圖，因此，學界之基 本電化學實驗，或業界之量產製程中設備，均以此示意圖為標準設計的參考，然而，此圖乃是一理想化之示意圖，該設計於電化學反應中將產生如反應面積不易估算、電極邊緣反應速率較快等缺點。 The general textbook's reaction to electrochemistry is often explained by a simple diagram. The anode is also called the oxidation pole. It is easy to lose electrons or ionize during the reaction. The cathode is also called the reduction pole. It is easy to get in the reaction process. Electron or accept positive ions, and the applied voltage/current value and electrolyte composition, concentration, temperature, and stirring are important parameters for controlling the reaction rate. Since the schematic diagram is a simple and easily accepted reaction mechanism diagram, Foundation of the academic world This electrochemical experiment, or the equipment in the mass production process of the industry, is based on this schematic diagram as a standard design reference. However, this figure is an idealized schematic diagram, which will produce an easy estimation of the reaction area in the electrochemical reaction. , the electrode edge reaction rate is faster and other shortcomings.
為了改善以上示意圖於實際電化學反應中所產生之缺點，一些較精密的電化學量測實驗常以管罩式為設計，即工作電極(working electrode)表面利用一個已知表面積之玻璃管罩住，管內裝有電解液，而對極(counter electrode)電極則由管之上端開口處置入管內，並於管內形成一電化學反應系統，此設計可改善反應面積的量測與局部反應速率不均勻的問題，但是管內之電解液容量有限，易造成長時間反應後之濃度下降的情形。槽狀式為另一種電化學反應設計，乃是將工作樣品固定於電解槽外，而電解槽壁之開口面積即為樣品之反應面積，再將對極電極置於電解槽內，此設計可解決電解液濃度下降的問題，然而此設計之缺點在於裝卸工作電極時易造成電解液洩漏，或是需將電解液事先由反應槽內取出的缺點。 In order to improve the shortcomings of the above schematic diagram in the actual electrochemical reaction, some more precise electrochemical measurement experiments are often designed with a tube cover type, that is, the working electrode surface is covered with a glass tube of a known surface area. The tube is filled with electrolyte, and the counter electrode is disposed in the tube from the upper end of the tube, and an electrochemical reaction system is formed in the tube. This design can improve the measurement of the reaction area and the local reaction rate. The problem of unevenness, but the electrolyte capacity in the tube is limited, which tends to cause a decrease in the concentration after a long period of reaction. The groove type is another electrochemical reaction design, which is to fix the working sample outside the electrolytic cell, and the opening area of the wall of the electrolytic cell is the reaction area of the sample, and then the counter electrode is placed in the electrolytic cell. The problem of lowering the concentration of the electrolyte is solved. However, the disadvantage of this design is that the electrolyte is easily leaked when the working electrode is loaded or unloaded, or the electrolyte is required to be taken out from the reaction tank in advance.
針對以上工件在反應過程中的電流密度與溫度控制的穩定性，本發明專利將提出不同設計之電化學處理用治具設計來提升量產形電化學製程的穩定性。 In view of the current density and temperature control stability of the above workpiece during the reaction process, the present invention will propose a design of an electrochemical treatment jig of different designs to improve the stability of the mass production electrochemical process.
