Before buying NdFeB magnets, customers need to know the following poits:
[1] The circular dimension is usually expressed in D (because it is a special symbol that most people use D instead of_). For example, D10X1MM is a magnet with a diameter of 10 mm and a thickness of 1 mm. This is the mathematical symbol "multiplier symbol".
[2] The size of a square is long, X-shaped, wide and X-shaped. This square is usually represented by F. For example, f50x25x13mm represents a square magnet with a length of 50mm, a width of 25mm and a thickness of 13mm. Normally, the number at the end of the default value represents the magnetization direction of a square magnet. For example, the magnetization direction of f50x25x13 is 13 mm, that is, high magnetization direction. NS is the largest two aspects, i. e. 50 x 25 sides.
[3] The size of the ring is expressed as the height of the outer diameter DX and the inner diameter dx. For example, the ring magnet of D32XD18X 6 represents an outer diameter of 32 mm, an inner diameter of 18 mm and a height of 6 mm. Height is also called thickness. At present, the rings are also divided into straight holes and sinking holes. The straight hole is drilled vertically, and the sinking hole is divided into large hole and small hole. The depth of large and small holes is usually called screw holes.
What should I pay attention to when using strong magnets?
1. When using magnet in the working environment, we must pay attention to ensure that the environment around the magnet is very good. Now strong magnets
In the market, it still has great potential for development and is widely used. When working with magnets, the most important thing to pay attention to is neatness and cleanliness, because
In the relatively poor environment, strong magnet can not work properly. Because it's for things like iron scraps or tiny particles.
Still not very able to absorb, if the working environment is poor, then the magnet will easily lose its magnetism, and ultimately lead to shorter service life.
Therefore, keeping the working environment clean is the most important requirement of the powerful magnet.
2. Indoor environment is another important issue. Generally speaking, we should pay attention to the indoor environment when we preserve the strong magnet, so as to ensure the indoor environment.
The air is unblocked, and you can't choose a humid place to store it. You have to choose a dry environment. Powerful magnet Powerful magnet is not only for
There are requirements for the working environment, as well as for the indoor environment. Its indoor ambient temperature should not exceed the working temperature of the magnet.
Those products that have not been electroplated can be properly oiled to prevent rust. When storing magnets, be sure to isolate some sensitivity
