摘要
采用磁浆涂布工艺制作了磁鼓涂层材料.研究了不同组分的配方对磁鼓涂层材料性能的影响,制备出性能良好的磁鼓.对φ32-40mm的磁鼓进行了充磁测试,写入了128和256 对极.采用金属薄膜磁电阻传感探头检测磁鼓表面分布磁场,信号通过电路放大、整形后接入示波器和计数器,结果显示输出信号波形良好,计数完整.
Magnetic drum coating material was prepared by using the magnetic slurry inunction process and the influence of component on the property of coating material was investigated. A high-performance magnetic drum whose diameter is 30-40 mm was ultimately manufactured with this material. The magnetic drum was magnetized and recorded 128 and 256 magnetic poles. A metal film magnetoresistance transducer was used to detect the distributing magnetic field of the drum surface and the signal was transformed to an oscillograph and an arithmometer by a magnifying and plastic circuit. It is shown that the output signal waveform is fine and the count is integrated.
