The function of insulating paint
Insulation performance: The main function of insulation paint is to isolate the conductive core material from the external environment. For example, on a dense circuit board, there are many different circuit components and lines. Without insulation paint, jumpers can easily come into contact with adjacent lines, causing circuit failures. The insulating paint can withstand a certain voltage without being broken down, ensuring that the current is transmitted inside the jumper according to the predetermined path.
Protective performance: It can also prevent the conductive core material from being corroded by the external environment. For example, in humid environments or situations where chemicals are present, insulating paint can prevent moisture and chemicals from coming into contact with the core material, thereby extending the service life of jumper wires. In addition, insulating paint can provide a certain degree of mechanical protection, reducing the possibility of damage to the core material due to external collisions, friction, etc.
Production process
Core material preparation: Firstly, suitable conductive materials such as high-purity copper wire should be selected as the core material. These copper wires usually need to go through a drawing process to draw thicker copper rods into fine wires of the required diameter to meet different current carrying and size requirements. During the drawing process, it is important to ensure that the surface of the copper wire is smooth, which is beneficial for subsequent insulation coating.
Insulation paint wrapping: There are various methods for wrapping insulation paint. A common method is dip coating, which involves passing the copper wire through a container filled with insulating paint to evenly adhere the paint to the surface of the copper wire. Then, through the drying process, the insulation paint is cured on the copper wire. Another method is spraying, where insulating paint is evenly sprayed onto the surface of copper wire using a spray gun, and then dried. In this process, it is necessary to strictly control the thickness and uniformity of the paint layer, as a too thick paint layer may affect the flexibility of the jumper, while a too thin paint layer may not provide sufficient insulation performance.
