摘要
在对磁场处理循环水的DO ,pH ,ORP和温度等变化的测定 ,以及磁场处理水通过生锈铁管时 ,红锈逐渐变成黑锈的X线分析基础上 ,探讨了磁场水处理对生锈铁管的除锈、防锈机理。磁场水处理使得Fe2 O3在铁管表面形成致密的复合氧化物Fe3O4 ,对铁管起保护作用。
The magnetic field treated circulating water was examined for DO, ORP, pH and temperature and the hematite and the magnetite that appeared longitudinally inside the steel pipe along the passage of magnetic field treated water were examined by X Ray for their constitution. On the basis of above mentioned examinations, the anti rust mechanism of the magnetic field treated water to the steel pipe was discussed. It was found that the magnetic field treated water accelerated the hematite(Fe 2O 3) to transform into the magnetite(Fe 3O 4) which formed a compact layer of composite oxides on the inside surface of the pipe and so the pipe was protected.
