The principle of etching process of etching machine

In a professional sense, the principle of etching refers specifically to the process by which metals are etched according to design and process requirements through professional means Etching machine A controlled corrosion behavior is carried out. Through this controlled chemical processing, certain design requirements for specific occasions can be met, which cannot be achieved by traditional mechanical processing methods. Metal chemical corrosion, which refers to the chemical damage caused by the chemical destruction of metals in the natural environment, is widely accepted as the chemical loss behavior of metals caused by chemical or electrochemical reactions between metals and surrounding environmental media. From this definition, various types of corrosion of metals are actually chemical losses of metals. There are four popular language expressions for metal chemical loss: chemical corrosion, chemical etching, chemical milling, and chemical texture etching. These four statements can be understood from the following aspects:

Etching equipment

Chemical corrosion: Chemical corrosion is a common phenomenon and process of metal chemical loss, including the destructive corrosion of metals in various corrosive environments, as well as the corrosion caused by controlled processing using chemical methods. From the perspective of the entire process, it includes both uncontrolled corrosion and controlled etching, which is a general term for metal chemical loss and a chemical loss behavior of metals in various chemical corrosion media. Many etching machine manufacturers, such as Hebei Ruisite Company, use this etching method.

Chemical etching is highly targeted and refers to controlled corrosion. It is a controllable processing method for metals through chemical methods. Chemical etching can be further divided into chemical milling and chemical texture etching based on the surface effect and X requirements after etching.

Chemical milling has the same meaning as mechanical iron cutting, only using different processing methods. Chemical milling requires the surface after chemical etching to have the highest possible surface smoothness, the lowest possible surface roughness, and the highest possible etching accuracy.

Chemical texture etching: Chemical texture etching refers to the surface effect with a certain roughness after chemical etching, and the size of this roughness can be adjusted within a certain range by controlling the chemical and physical indicators of the process. These chemical indicators include: the type of corrosive agent used and the concentration ratio between them; The physical indicators include etching temperature, etching time, and etching method.
