Magnetic tubes are mainly used to filter various fine powders and liquids, iron-containing impurities, and other magnetic substances in semi-liquids, and are widely used in chemical, food, waste recycling, carbon black, and other fields. A good magnetic bar should have evenly distributed magnetic induction lines, and the distribution of high magnetic induction points should fill up the entire magnetic bar as much as possible because it is generally placed in the moving product transmission line. Environmentally harmful substances, avoid pollutants and the environment. The working environment determines that it must have certain corrosion resistance and high-temperature resistance characteristics, and some occasions require relatively strong magnetic induction.
The surface magnetic induction intensity of the magnetic rod is proportional to the size of the small particles that can be adsorbed. In fields such as batteries and pharmaceuticals, tiny iron impurities can also have a big impact, so around 12000 gausses should be used. Other regions can choose lower. The characteristics are dense magnetic poles, good iron removal effect, large contact area, and strong magnetic force. The iron removal container can be customized and processed according to user requirements.
Mainly used in plastics, food, environmental protection, filtration, chemical industry, electric power, building materials, ceramics, medicine, powder, mining, coal, and other industries.
How to protect the magnetism of the magnetic tube
A bar magnet has a degree of magnetism, which you can tell by using it. However, as it is used, its magnetic properties may gradually decrease, but if its magnetic properties decrease, it may be unfavorable for its use. How to protect its magnetism?
1. Do not let the magnetic wand move vigorously, such as hitting or smashing.
2. Keep away from high temperatures.
3. Keep the magnetic stick away from the magnetic field.
4. Avoid heating at high temperatures.
Then in order to protect the magnetism of the magnetic rods, in addition to using them correctly, another way is to keep the magnetic rods away from some adverse factors and avoid using them under harsh conditions. Effectively protect the magnetic force, in order to prolong the service life.
Magnets are products that can generate strong magnetic force. It can be widely used in many industries and has good characteristics.
Magnetization Process
1. Reversible displacement of domain walls. In the case of a small external magnetic field, for magnetic domains whose spontaneous magnetization direction is the same as that of the external magnetic field or at a small angle, the magnetic domains will expand due to the low magnetostatic energy of the bar magnet. Instead, those spontaneous magnetizations are in the opposite direction to the external magnetic field. Or the magnetic domain shrinks at the obtuse angle.
2. Irreversible displacement of domain walls.
3. Rotation of magnetic domains and magnetic moments. The process is to increase the magnetocrystalline anisotropy and works so that it is difficult to rotate and the magnetization is weak.
4. Paramagnetic magnetization stage. Despite the large increase in the external magnetic field, the increase in magnetization is small. The increase in the magnetization of the bar magnet is partly due to the reversible rotation of the magnetic domain moments and partly due to the improved irregularity of the fundamental magnetic moments in the magnetic domains.
Precautions for strong magnetic rods:
1. When using, pay attention to the cleanliness of the workplace and avoid using small magnetic particles such as iron filings. It is characterized by being hard and brittle, its suction can reach more than 600 times its own weight, and it is easy to be absorbed and damage. Therefore, collision and damage must be avoided during operation.
2. When storing, the environment for storing magnetic rods should be ventilated and dry, because it is easy to rust in a humid environment. The ambient temperature cannot exceed the specified operating temperature. In addition, non-plated products should be properly oiled during storage to prevent rust.
