Abstract
The invention provides a corrosion-proof radial-anisotropy magnetic ring. The corrosion-proof radial-anisotropy magnetic ring consists of a magnetic ring body, an insulating coating and a corrosion-proof protective film sequentially from inside to outside, wherein the magnetic ring body is a NdFeB permanent-magnet magnetic ring, the insulating coating is a nylon coating, the corrosion-proof protective film is a nickel-chromium film, which is prepared through baking the following raw materials in parts by weight: 12-16 parts of nickel powder, 1-2 parts of chromic oxide and 0.02-0.04 part of film forming assistant, the thickness of the nylon coating is 60-80 microns, and the thickness of the corrosion-proof protective film is 60-80 microns. The corrosion-proof radial-anisotropy magnetic ring provided by the invention has the following technical effect that the NdFeB permanent-magnet magnetic ring can be protected, and thus the magnetic property cannot be lowered even the magnetic ring is subjected to relatively strong corrosion.
Description
Technical field
The present invention relates to a kind of anticorrosion footpath anisotropy magnet ring, belong to technical field of magnetic materials.
Background technology
Magnet ring is a kind of novel cheap and good-quality AF panel device, is utilize high magnetic conductive material, oozes metals such as closing other one or more magnesium, zinc, nickel, burns poly-forming at 2000 DEG C.It is anti-interference element conventional in electronic circuit, has certain impedance operator, has good inhibitory action for high-frequency noise.Be applicable to computer monitor, printer, photocopier, digital camera, communication apparatus, household electrical appliance, communication power supply, winding displacement, power line, USB linear system row anti-jamming effectiveness.Its effect is equivalent to low pass filter, solves power line preferably, and the High-frequency Interference of holding wire and connector suppresses problem.And have and use simple, convenient, effectively, the series of advantages such as take up room little.Disturbing magnet ring with anti-thousand and suppress electromagnetic interference (EMI), is economical and convenient and effective method.
Under certain environment for use, if magnet is subject to stronger corrosion, magnetic can be caused to decline, therefore improve the anticorrosive property of magnet.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, a kind of anticorrosion footpath anisotropy magnet ring is provided.
Anticorrosion footpath of the present invention anisotropy magnet ring; from inside to outside; be made up of magnet ring body, insulating coating and anti-corrosion protective film successively; described magnet ring body is Nd-Fe-B permanent magnet magnet ring; described insulating coating is nylon coating; described anti-corrosion protective film is nickel chromium triangle film; described Zinc-Chromium film is toasted by following raw material and is formed: nickel powder 12-16 weight portion; chromium oxide 1-2 weight portion; coalescents 0.02-0.04 weight portion; the thickness of described nylon coating is 60-80 micron, and the thickness of described anti-corrosion protective film is 60-80 micron.
Preferably,
The thickness of described nylon coating and the Thickness Ratio of anti-corrosion protective film are 1:1.
Described anti-corrosion protective film is covered with titanium oxide layer.
Anticorrosion footpath of the present invention anisotropy magnet ring, has following technique effect: can protect Nd-Fe-B permanent magnet magnet ring, even if be subject to stronger corrosion, magnetic also can not be caused to decline.
