Metal etching processing need to pay attention to what

Hello everyone, today I want to share with you metal etching processing. etching processing is a process that removes the surface of a material through a chemical reaction, and is mainly used to treat metal materials. metal etching processing can realize a variety of complex designs and patterns, and is one of the most common processing methods in metal craft products.

In the process of metal etching processing, etching solution is a key component, the main components are ferric chloride and aluminum oxide. Through a mixture of various chemicals, it can destroy the oxide film on the surface of the metal, so that the material reveals the underlying color, as in the production and production process will be through the wet film drying to protect the material from erosion, and the unprotected layer will be corroded off. The choice and proportion of etching solution needs to be adjusted according to different materials and environment, and there are certain requirements for technicians, as well as the protection of personnel.

In addition, metal etching processing also needs to pay attention to some details. For example, the processing temperature and time should be strictly controlled to avoid excessive or insufficient; the processing area should be kept clean to avoid the interference of impurities; etching solution should be regularly replaced to ensure quality, etc..

In short, metal etching processing is a very complex and delicate process that needs to be carefully designed and adjusted to achieve the best results. Metal etching processing will produce a large amount of wastewater, this wastewater has a high degree of corrosiveness to the environment has serious pollution, in order to completely solve the problem of strength of the metal etching manufacturers to use is to establish an independent and autonomous environmentally friendly recycling system, for the system can minimize the pollution, effective protection of the environment.
