네오디뮴 자석 안전

네오디뮴 자기 건강 & Safety

Important health & safety information regarding Rare Earth Neodymium Magnets.

Liability

UMAGNETICS (UMAG) 자석의 부적절한 취급으로 인해 발생한 손상에 대해서는 책임을 지지 않습니다.. 이 자석을 구입하면, 귀하는 다음 경고를 읽고 이해했음을 확인합니다.. A health and safety warning sheet is supplied with all orders, so if you are giving magnets as a gift, please be sure to include the information sheet in the package. Ensure that children under 13 are not allowed to play with magnets and children over 13 are told about the potential dangers of the stonger magnets and supervised by an adult who has read and understood these warnings.

Danger of breaking or chipping

The most common cause of broken magnets is when two magnets are released and allowed to collide together. A combination of massive acceleration and high forces will cause one or both magnets to chip or shatter. Please do not allow this to happen and then try to return them to us as ‘broken in the post’.
The chips are usually magnetically pulled back by the main ndfeb magnets but it is conceivable that they may fly off at high speed into someone’s eye. Eye protection is therefore advised. Chips and broken magnets are quite sharp, so cuts are possible as with broken glass.

Danger for children

Do not let children under the age of 13 play with Rare Earth neodymium magnets and always supervise any child playing with these magnets. 작은 자석 여러 개를 삼킨 경우, 장에 걸려 큰 부기를 유발할 수 있습니다., 생명을 위협하는 부상이며 이를 제거하기 위해 수술이 필요함. 텔레비전 화면이나 컴퓨터 모니터 화면 위에 올려 놓는 경우, 색상이 영구적으로 왜곡되어 영구적인 손상이 발생할 수 있습니다..
더 큰 자석을 유지하세요 (1cm2 이상) 아이들의 손이 닿지 않는 곳에, 칼이나 기타 위험한 물건을 날카롭게 하는 것처럼, 강력한 자석 사이에 손가락이 끼일 수 있으므로.

눌러 터뜨리는, 혈액 물집과 상처

더 큰 자석을 서로 충분히 가까이 가져가면 놀라운 양의 힘을 가질 수 있습니다.. 손가락이 손가락 사이에 빠르게 끼어 혈액 수포나 상처가 발생할 수 있습니다.. 더 큰 자석을 다룰 때는 장갑을 착용하고 주의하십시오.. 작은 자석을 먼저 다루는 연습을 하세요.. Do not place these magnets up your nose or around the ears as they have soft tissue that will compress as the powerful magnets attract through the thickness of the tissue and as the magnets get closer as a result, they exert yet more force which crushes still further etc.

Magnetically sensitive items

Rare Earth Permanent Neodymium magnets are very much stronger than “ordinary” magnets. Keep a safe distance (200mm+) between the magnets and all objects that can be damaged by magnetism. These include mechanical watches, heart pacemakers, CRT monitors and televisions, 신용 카드, motor, rotor, diskettes and other magnetically stored media such as video tapes.

Heart Pacemakers

The operation of heart pacemakers will be affected by the close proximity of a magnet. 자석은 심박조율기 사용자에게 적합하지 않고 건강에 영향을 미칠 수 있는 방식으로 심박조율기가 작동하도록 설정할 수 있습니다.. 자석을 제거하면 이 변화가 중단됩니다..

표면 도금 – 마모 및 치핑

HangSeng Magnetech의 희토류 영구 네오디뮴 자석은 일반적으로 다음과 같이 도금됩니다. 3 보호 도금층. 먼저 니켈 층, 그 다음 구리 층, 마지막 니켈 층. 다른 것들은 이중 니켈로 도금됩니다., 아연, 색상 아연, 주석, Ni-Cu-Sn, 에폭시 (블랙 코팅), Ni-Cu-에폭시, Zn-에폭시, 파릴렌 코팅. 코팅 구조를 보려면 여기를 클릭하세요.. 이러한 도금은 강철 표면에 미끄러지거나 충격을 가하면 정상적인 사용 과정에서 마모될 수 있습니다.. 도금층이 마모된 경우, then the magnet will be exposed to corrosion and since the magnets contain a high percentage of iron, they will rust easily. It is always better to use the magnet in a way that mechanically prevents it from ever touching the part that it is attracting. A mechanical stop which holds the magnet 0.2mm away from the attracted part will ensure a very long life of the strong magnet.

Cutting or drilling Neodymium Magnets

Neodymium magnets can be secured in place with adhesive or in some cases, with countersunk screws. Magnets are sintered and extremely hard and brittle. You should never attempt to cut or drill into a magnet unless using diamond tooling and coolant (as the dust from cutting is very flammable).

Nickel allergies

Our Rare Earth Permanent Neodymium magnets are nickel-plated. Nickel is a metal which can cause an allergic reaction in some people. Nickel allergies can be acquired through long-term contact with objects that release nickel. 대부분의 경우, these allergic reactions are triggered by nickel-containing jewellery (e.g., earrings or piercings, clips, rings or necklaces). As a precaution, avoid long-term contact with nickel-plated magnets (e.g., jewellery) and totally abstain from contact with nickel-plated materials if you already have a nickel allergy. How much or little it takes to trigger a nickel allergy is debatable (note the discussions regarding the Euro coins which contain 25% 니켈).

Effects on people

Millions of people worldwide wear Neodymium magnets to promote health and well being. We have found no evidence at all of detrimental effects of Rare Earth Permanent Neodymium magnets on people or animals – quite the reverse!
