With doubts, you may be searching for why magnets are painted, and where are the paint magnets used? What is the function of ferrite magnet spray paint? Don't worry, the article will help you out.
When I first entered the magnet industry, what I thought it was? Later I learned that the colored ones are also magnets, called paint magnets.
Spray paint magnets are actually colorful and multi-colored, yellow, green, and red magnetic rings. They really make the magnetic rings colorful, like a bride who is about to get married. Many of them are used for export.
Of course, these are not colored as soon as they are made, but the magnetic ring is made and sprayed with a layer of color. According to the needs of the customer, spray different colors. In fact, no matter what color the magnetic ring is sprayed on, it is the same. These are based on the needs and requirements of the customer. Whether the magnetic ring is sprayed with green paint or black paint, it has only one purpose, that is, it can achieve Good insulation effect, the main reason why the magnetic ring needs to be insulated is to prevent oxidation of the magnetic ring. If the magnetic ring is oxidized, it will also affect its characteristics and effects. For this reason, many customers require a layer of paint to be sprayed on the magnetic ring installed on the circuit board.
Many people wonder why the magnetic ring on the circuit board needs to be painted, while the magnetic ring on the wire is used without painting. Of course, there is a certain truth to this, because the magnetic ring installed on the circuit board is easier to oxidize, it drives the electronic components of the entire circuit board, and there is nothing to protect. While using the magnetic ring on the wire, some can be injection-molded to prevent its magnetic leakage, and some are directly threaded on the wire. These will not be involved in its oxidation. The reason is that the magnetic ring on the wire is used. After some negative effects caused by other electronic components, so it is not easy to oxidize, then there is no need to spray paint, which also reduces the cost of the magnetic ring for everyone. Spraying a magnetic ring paint will greatly increase the cost. The painting requires labor and the cost of painting. If there is no specified requirement, the magnetic ring that can not be painted should not be painted as much as possible. The magnetic ring that needs to be painted cannot be reduced. Cost, but cut corners; this will affect the quality of the entire electronic product. If there is no cost requirement, try to spray paint or use some vanishing water, which can play a good insulation effect and prevent the oxidation of the magnetic ring.
