In recent decades, chemical etching machine, which uses chemical etching as a high-precision and scientific chemical etching processing technology, has been widely used in the processing of various kinds of pictures and shapes on metal materials. Especially in aerospace and aviation industry, almost everywhere we can see the products produced by chemical etching technology applied to life. However, as a chemical thinning cutting technology, its history can be traced back to a very long time. The technology of chemical etching has not been recorded in China for a long time. The main reason is that ancient China did not pay enough attention to science and technology,. In other western countries, the application of chemical etching technology has been recorded for a long time. The earliest record is that the use of NaOH and Al2 (SO4) 3 was discussed in the West in the first century B.C., which is certainly exaggerated. There are two conditions for the application and development of metal corrosion, one is the popularization and application of metal, the other is the deployment of etching solution corresponding to metal. The discovery and application of metals have a longer history. In this respect, China has a longer history than other countries. It mainly comes from the means of ancient alchemists. The first discovered materials are copper and alloy, and then iron.. Aluminum has been discovered for hundreds of years and refined before being used in daily life. Therefore, there is no basis for people in the west to discuss the use of NaOH and Al2 (SO4) 3 in the first century B.C.
The development of metal corrosion is mainly from three aspects:
The discovery of metal and the development of smelting technology;
The allocations of etching solution.
In the present life, corrosion is very common, but in the ancient times, this kind of situation is impossible, because that time was composed of wood, stone, and soil. Until the ancients mastered the metal refining technology to separate the metal from the attached materials, they got the metal. With the discovery of metal, people began to think of ways to use it. Corrosion is involved in the application here, but many liquids can not be processed on the metal surface quickly, which requires the material acid that can produce corrosion with metal. The earliest acids are organic acids, such as lactic acid from acid resistance, citric acid and acetic acid from lemon, among which the strength of acetic acid is the strongest. Only these organic acids are difficult to make effective corrosion processing for metals. Later, when inorganic acids are found, metal chemical corrosion processing will be applied and developed. Therefore, the chemical etching of metals should be done after the letter of inorganic acid, which is also related to the early and late discovery of anti-corrosion materials of plasma etching machine. In Europe, chemical etching became popular in the 15th century, when it was mainly used for the etching of armor and crafts. The etching solution formula of the reconstructed record is made of salt, activated carbon and acetic acid. The protection is mainly made of linseed oil coating and paraffin as anti etching materials to realize image transfer of the protective layer.
