What are the precautions for the storage and transportation of magnets?
As a special product, how is magnet transported and what should be paid attention to?
First of all, how to store magnets?
To pay attention to indoor humidity, must be maintained at a dry level. The temperature should not exceed room temperature; products in black block or blank state can be properly oiled (general engine oil is enough); electroplating products should be stored in vacuum sealing or isolated from air to ensure corrosion resistance of coating; magnetizing products should be packed together and stored in boxes to avoid sucking up other metal bodies; magnetizing products should be stored away from disk, magnetic card, tape and computer display A device, watch, etc. that is sensitive to magnetic fields.
How to transport magnets? What should we pay attention to?
There are two main problems in magnet transportation, one is how to protect the magnet, the other is how to prevent the damage of magnet magnetic field to the surrounding environment and personnel.
First of all, we must ensure that the environment in which the magnets are stored during transportation is dry. If the humidity is relatively high, it is easy to cause the magnets to rust. You can also use some anti rust oil on the surface of the magnet, which can prevent the magnet from rusting. For the magnet with electroplated coating, it should be transported in vacuum to prevent corrosion of electroplated coating.
In addition, the temperature of transportation must not be too high. Generally, demagnetization will occur when the magnet exceeds 80 degrees. Therefore, during transportation, try to keep it at room temperature. Secondly, in order to prevent collision between magnets during transportation, which may cause damage, it is better to separate magnets with wooden board. In the process of transportation, we must prevent the fierce collision. In the process of transportation, the operator should handle it with care.
Next, it is to solve the impact of magnetic field on the environment. First of all, try not to transport magnets together with computers, watches and other items sensitive to magnetic field. For the problem of how to shield the magnetic field, the simplest way is to wrap the magnet with iron sheet or carbon steel plate, and then arrange the magnetism of the magnet to form a good magnetic circuit inside. When choosing the means of transportation, maglev train and air transportation are good choices. However, the price will be higher. Moreover, if air tranportation is carried out, the shielding of magnetic field will be more strict.
