【 Can talk about a powerful magnet logistics by air? 】 Powerful magnets can go by air? Needs to entrust specialized agencies, Bureau of technical supervision) Do demagnetization, so-called demagnetization, magnetic actually didn't disappear, just the objects in the unit packaging, the unit packing foreign showed magnetic reached national aviation transport safety requirements of the rules. The world of aviation goods transport total conditions a powerful magnet and magnet requirements; YouJiRen shall abide by the world air transport association packaging to clarify except 902 still need the following requirements, in order to avoid the aircraft looks especially compass they produce interference, YouJiRen for magnetic materials shall pack the goods according to the following way: every package of magnetic materials is necessary in accordance with the air transport association rules chapter 7 of the rules of dangerous goods correct symbols and labeling. Ensure that before the goods by mail, is apart from the 4 package appearance. 6 m ( 15 feet) In measured magnetic field strength is not exceed 0. 418 / m ( 00525 gauss) 。 Magnetron and illuminance meter instrument and device instead of magnetic pole relative placement is necessary. Permanent magnet material is necessary to add retentivity armature non-maskable may, in case the magnetic field forms a compass error appearance. Above when magnetic material as a dangerous goods inspection standard, the domestic customer to magnetic materials as non-dangerous goods for air shipment, the shielding requirements: demand guarantee, before the goods send from packaging appearance. 2. 7 meters are no more than 200 nt (measured magnetic field strength Is equal to 2 the mGs = 0. 002Gs) 。 In order to ensure the gauss meter measurement accuracy and ensure that as far as possible not by the influence of the magnetic field, general customers in packaging appearance between 0. 5 meters to measure, according to the theory of accounting & lsquo; The interval is inversely proportional to the square in the magnetic field strength & rsquo; The closer is the interval measurement to the magnetic field intensity. For example: 2. 7 meters measurement magnetic field range of 0. 002 Gs, in accordance with & lsquo; The interval is inversely proportional to the square in the magnetic field strength & rsquo; The theory formula strictly in packaging appearance between 0. 5 meters to measure, the basis of the magnetic field should be 0. 05832 Gs。 Shorten 5 interval. Four times, that is, intrusive amplification 29 magnetic field. 16 times. Example: customers produce a batch of N35 type of powerful magnet but cannot deliver, due to reach the world aviation association packaging requirements. Powerful magnets by air Courier, objects are defined as dangerous goods, export difficulties. But the delivery date is coming at once, actually can cope with this problem, is to go to Hong Kong DHL. From a third party transit transshipment in Hong Kong DHL, seemingly can completely deal with this problem, is also a demand in accordance with the requirements for magnetic separation packaging. Strong magnets, magnets, magnet, magnet, ndfeb magnet, rare earth permanent magnets
