Mechanism elucidation and application of scale prevention effect on water pipe by electromagnetic treatment

为了揭示电磁处理防垢的机理，对蒸汽发生器和冷却装置进行了示范实验。通过实验，证实了电磁处理的有效性和由电磁场频率引起的反向充电效应，沿着这种反向充电现象在实际使用中的高有效性，当添加阳离子水处理化学品时，这是显著的。揭示了电磁处理的水质控制标准值，并证明了在整个操作过程中控制该值在很大程度上抑制了水垢的粘附。

We conducted a demonstration experiment of steam generator and cooling facility in order to reveal the mechanism of scale prevention effect by electromagnetic treatment. Through the experiment, effectiveness of the electromagnetic treatment and the opposite-charging effect by electromagnetic field frequency were confirmed, along with the high effectiveness in practical use of this opposite charging phenomenon, which is remarkable when cationic water treatment chemicals is added. The water control standard value for electromagnetic treatment was revealed as well, controlling of which throughout the operation was also proven to inhibit scale adhesion to a large extent.
