What should we pay attention to in electrogalvanizing?

Electrogalvanizing is a common surface treatment method, mainly used in steel, iron, copper and other materials surface anticorrosion. In the process of electrogalvanizing, many things need to be paid attention to. The following Shanghai electrogalvanizing processing manufacturers will introduce in detail the matters needing attention for electrogalvanizing processing.

1. Preparation before processing

1, surface preparation: Before electrogalvanizing processing, it is necessary to fully clean the surface of the material, remove the surface oil, oxide layer and other substances, to ensure that the surface is clean and smooth, so that the coating can better adhere to the substrate.

2, material selection: In the process of electrogalvanizing, it is necessary to select materials that meet the specifications and have reliable quality to achieve the advantages of good quality and long life of the electroplating after processing.

3, equipment testing: before processing, it is necessary to test the working state of the equipment, the pH value of the oxidation liquid, the stirrer, the heater and other equipment is working normally.

2. Control of the processing process

1, temperature control: in the electrogalvanizing processing, it is necessary to keep the temperature of the heater within a certain range, otherwise it will cause poor quality of the coating or other defects.

2, movement mode: need to control the movement mode, so as not to appear local too hot, resulting in uneven coating after processing.

3, voltage and current control: Fluctuations in voltage and current may reduce brightness and even corrosion resistance, and it is necessary to control the spacing and quality of voltage and current during processing.

Third, security issues

1, chemical protection: chemicals play an important role in the process of electrogalvanizing, but the chemical itself has a large corrosive. Before processing, it is necessary to fully understand the characteristics of the relevant chemicals and do a good job of chemical protection, such as wearing safety equipment such as gloves and ventilators during operation.

2, electrical safety: the use of electricity in the process of galvanizing, if the equipment is improperly maintained, may cause electrical accidents, resulting in personal injury.

3, equipment safety: electric galvanizing processing equipment to be fully maintained, the use of the need to carefully check the indicators of the equipment, so as to avoid equipment failure.

Summary: The above is the electrogalvanizing processing needs to pay attention to matters, electrogalvanizing processing needs to be operated in strict accordance with the specifications to ensure that the electroplating after processing is of good quality and long life. In the process of processing need to pay attention to safety issues, take effective protective measures to ensure the personal safety of processing personnel.
