Generally, when welding aluminum enamelled wire, we often need to remove the paint (except for some). At present, there are many kinds of paint removal methods in actual use, but different methods need to be used in different situations. Next, let me introduce the advantages and disadvantages of the more common paint removal methods.
At present, the common methods of stripping aluminum enamelled wire are as follows: 1. Scraping with a blade; 2. The paint can also be ground off with a grinding wheel; 3. It can be peeled with a centrifugal knife; 4. Paint remover can also be used.
The method of scraping paint with a blade for aluminum enamelled wire is more traditional and has no technical content. We use special tools to cause less damage to the surface of aluminum enamelled wire. Without high temperature, the aluminum surface will not form oxide film and the wire will not become brittle. However, the efficiency is low. It is only applicable to the paint stripping of large wires, and it is not applicable to wires with a diameter of less than 0.5mm.
The second is the centrifugal knife, which directly strips the paint of aluminum enameled wire through three high-speed rotating knives, which is more efficient. However, this paint stripping method is similar to manual paint scraping, which is only applicable to the paint stripping of large lines.
There is also the grinding wheel method of aluminum enamelled wire. If the wire is thick, this method can be selected. If the wire is thin, it is still not the preferred method.
Another is paint remover. This method does little harm to the aluminum of aluminum enamelled wire, but it is basically useless for high-temperature wire, so it is not suitable for high-temperature wire.
The above are some commonly used paint removal methods for aluminum enamelled wires, but different methods have different application ranges. You can choose the appropriate paint removal method according to your actual situation.
