一种非化学药剂阻垢新技术研究

Low frequency electro-magnetic treatment for scale inhibition

利用钙离子浓度和电导率的变化研究了低频电磁场对碳酸钙结晶的影响,分析了碳酸钙结晶的微观结构。结果表明,磁效应促进了水样中碳酸钙晶核的生成却抑制了晶粒的长大,从而达到阻垢的目的。

Effects of the low frequency electro magnetic field treatment of water on the crystal structure of CaCO3 was determined by monitoring the changes in conductance and Ca^2＋ concentration of the treated water and studying the mierostrueture of crystalline CaCO3. The low frequency electro-magnetic field treatment accelerated the formation of CaCO3 particles but inhibited the particle growth; it effectively prevented the particles from forming the undesirable scale.
