Next we come to understand the corrosion signs made of the advantages and disadvantages of the electrolytic etching process. Actual is electrolytic electrolytic etching a metal materials, such as electrolytic copper, iron, etc. Particular way is made the anode will be etched parts, the use of corrosion resistant metal materials in auxiliary cathode. Connect the anode power supply of the anode, cathode connection power of the cathode. When an electric current passes through the electrodes and the electrolyte solution, on the surface of the electrode and the electrochemical reaction that occurs in the electrolyte solution to take advantage of this reaction is going to dissolve to remove part of the metal, achieve the goal of metal corrosion. Corrosion sign factory introduced corrosion sign making electrolytic etching technology advantages: 1, less investment, electrolytic etching machine market price is not high, even can be modified or assembly. 2, the operation is simple, etching liquid of low cost, easy solution, strong adaptability to different metal also. 3, small batch production speed, depth is relatively easy to control, is often used to etch stainless steel plate. 4, for chemical etching machine can't do big sign, can consider to use. 5, polluting, more environmental protection. Corrosion sign factory introduced corrosion sign making electrolytic etching technology advantages: 1, is not suitable for mass production, the production efficiency is low. 2, resistance to etch film over the use of signs have higher requirements, better insulation, can the current breakdown, ordinary screen printing ink is not can use. 3, for large area uniformity of etching is difficult to ensure depth. 4, for a very fine line, easy to etching occurred, we often use the brush brush way is difficult to control engraved in etching time, time is short, the depth of less than, long time is easy to down line is damaged, it is a very prominent problem. 5, prone to poor contact, light circuit, sign the partial burning, etc. 6, for some metal etching is slow, the efficiency is low. For example, aluminum, etc.
