能够空运钕铁硼强力磁铁吗？空运运输鉴定报告

First, some revisions to the content are required to improve its fluency and reduce redundancy. The suggested optimized version is as follows:

1. Can NdFeB powerful magnets be shipped by air?

Yes, NdFeB powerful magnets can be shipped by air. However, magnets need to be magnetically inspected before being shipped by air. Major transportation companies generally provide magnetic inspection services, and the cost of magnetic inspection for express companies is generally tens of yuan. Only after the magnetic inspection meets the aviation safety transportation standards can the transportation be carried out. Magnetic isolation packaging is required during transportation to ensure that the magnetism of the magnet will not affect other cargo and flight safety.

2. How should NdFeB powerful magnets be packed by air?

In foreign trade transactions, air freight is a relatively common mode of transportation. For foreign traders, it is very important to know how to pack NdFeB magnets.

If foreign customers buy NdFeB magnets from your online store and choose to ship them by air, it will be a troublesome thing. Because NdFeB magnets are fragile and magnetic, which may affect flight safety, they must be transported with care.

Some people think that NdFeB magnets are metal products, not fragile items, so there is no need to worry about damage. But in fact, NdFeB magnet is not metal, it is just a fragile magnet, the surface may be plated with a layer of nickel, zinc, gold and other metals. Therefore, among all kinds of magnets, NdFeB magnets are relatively fragile.

Therefore, if it is to be shipped by air, it is recommended that the NdFeB magnets be identified, and this work can usually be done at the Shanghai Institute of Chemical Technology.

3. How to pack NdFeB magnets?

Normally, foam boards and magnetic insulation boards can be used for packaging, and then the magnets are placed in eight-hole foam boxes specially for export.

Specifically, the packaging materials are as follows:

1. Polystyrene foam

The first and third layers are polystyrene foam, the first layer is used to protect the neodymium iron magnet, the third layer is used to protect the steel plate, and it can fix the goods well.

2. Magnetic isolation board

The second layer is a thin iron sheet, and usually 6 thin iron sheets are used in the box to shield or redirect the magnetic field generated by the neodymium-iron magnet, so as to ensure that the magnet will not affect other packages or aircraft.

These are all the materials you need to pack your neodymium iron magnets. Normally, a set of magnetic isolation boards weighs about 2kg. This packaging method is suitable for ordinary magnets and small magnets, but not for large magnets. This is because the magnetic field generated by a large magnet is so strong that it is difficult to change the direction of its magnetic field lines.

Large magnets are packaged as follows:

1. It needs to be packed with 3-5 layers of iron plates or packed in wooden boxes;

2. If the magnet size is very large, both magnets should be placed in the same box/container. Each magnet must be individually wrapped similar to the one pictured above to ensure the flux lines are kept small.

In short, if you want to export NdFeB magnets abroad, you must carry out magnetic isolation packaging. For a small amount of magnets (such as samples), they can be packaged directly with foam insulation, and the cost is relatively low. If the number of magnets is large, it is recommended to use a magnetic isolation board and a specially exported foam box for packaging.
