style="text-indent:25px">釹鐵硼磁鐵注意事項(xiàng)：釹鐵硼磁鐵的磁性非常強(qiáng)。你應(yīng)該首先避免用磁鐵握住手或身體的其他部位。對(duì)于大尺寸強(qiáng)磁性，你需要更加注意安全性。不要將強(qiáng)磁鐵連接到靠近電子醫(yī)療設(shè)備或攜帶起搏器和其他設(shè)備的患者身上。不要吞下強(qiáng)磁鐵。如果不慎吞咽，應(yīng)立即進(jìn)行醫(yī)療。強(qiáng)磁鐵應(yīng)該放在兒童夠不到的地方。在磁鐵的使用過程中，應(yīng)盡可能保持環(huán)境清潔，以避免細(xì)小雜質(zhì)如鐵屑吸附在磁鐵表面并影響使用。磁性碎片飛進(jìn)眼睛會(huì)造成傷害，需要小心使用。釹鐵硼磁鐵應(yīng)儲(chǔ)存在通風(fēng)干燥的環(huán)境中。酸性、堿性、有機(jī)溶劑、鹽水和高溫潮濕的環(huán)境會(huì)容易氧化磁體，電鍍層會(huì)脫落，磁體會(huì)被粉碎和消磁。磁體的磁性在高溫下加熱后會(huì)衰減。請(qǐng)參考溫度公差指南，了解磁鐵的相應(yīng)性能，組裝或使用磁鐵時(shí)注意不要超過標(biāo)準(zhǔn)工作溫度。釹鐵硼磁鐵是易碎的，所以當(dāng)它用于振動(dòng)、沖擊等場合時(shí)，它可能會(huì)斷裂或脫落。使用時(shí)一定要注意碰撞。無錫高精度磁鐵直銷廠家</p><p
