Engineer Deso said that the ambient humidity is an important factor that causes the copper parts of the M8 joint to become black and rusty. In a humid environment, water molecules react with copper to form copper oxide and copper hydroxide. These compounds form a thin film on the surface of the copper, causing the copper pieces to gradually tarnish and rust.
Oxygen is another important factor in copper rust. In an aerobic environment, copper reacts with oxygen to form copper oxide. Copper oxide is an unstable compound that is able to react further with water molecules and oxygen, resulting in continued rusting of copper parts.
Environmental contaminants, such as sulfides, nitrides, chloride ions, etc., can react with copper, causing copper corrosion and rust. These contaminants can come from the external environment such as air, soil, water sources, or from chemicals such as lubricants and cleaning agents inside the equipment.
M8 joint copper parts need to be heat treated during the manufacturing process. If the heat treatment is not done properly, it will cause the surface of the copper to oxidize or the internal structure of the copper will change, which will make it more susceptible to rust.
If the surface treatment of the copper parts of the M8 joint is improper, such as uneven plating, defective or not properly treated against rust, it will lead to an increase in the contact area with air and moisture, making it more likely to rust.
During the manufacturing process, if there are defects in the M8 joint copper parts, such as sand holes, porosity, inclusions, etc., these defects may become the starting point of corrosion, resulting in rust of the copper parts.
During the operation of the equipment, if the M8 joint copper parts are hit or rubbed, it may cause damage to its surface or destroy the original anti-rust layer, making it susceptible to corrosion.
If the copper parts of the M8 joint are not properly maintained and maintained during use, such as not being cleaned in time and not coated with anti-rust agents, etc., it will lead to pollution and erosion on its surface, which will make it easy to rust.
If the M8 joint copper parts are overloaded, the stress they bear will increase, which may cause stress corrosion cracking and make the copper parts more prone to rust.
For rust problems caused by environmental factors, humidity and contaminant levels can be reduced by improving environmental conditions. Equipment such as dehumidifiers and air filters can be placed around the equipment to reduce humidity and contaminant content, or rust inhibitors can be applied to the surface of copper parts to protect them from corrosion.
For the rust problem caused by manufacturing process factors, quality control and process management in the manufacturing process should be strengthened. Advanced manufacturing technology and equipment can be used to improve manufacturing accuracy and surface quality, and ensure that the anti-rust layer of copper parts is effectively implemented. At the same time, non-destructive testing techniques can be used to detect internal defects and structural changes in copper parts.
For the rust problem caused by the use factors, the use and maintenance management of the equipment should be strengthened. In the process of use, the damage to the surface of the copper parts by impact and friction should be avoided, and regular cleaning and maintenance work should be carried out. At the same time, it should be used according to the rated load of the equipment to avoid damage to copper parts caused by overload use.
