The presence of Mg〓 will change the crystallization process of calcium carbonate and produce aragonite scale. The presence of Zn〓 can prevent the formation of the crystal nucleus of calcium carbonate and then prevent the scale.

当水的硬度、温度增加时，水的结垢速率增加；SO〓和NaCl含量增加，能使水的结垢速率略有增加；Mg〓能改变碳酸钙的结晶过程并产生文石状的水垢；Zn〓的参与能明显阻碍碳酸钙微晶核的生成，从而达到阻垢的目的。

The water-scaling rate will increase when the water hardness or temperature is increased. The water-scaling rate will increase slightly when the concentration of SO〓 or NaC1 is increased. The presence of Mg〓 will change the crystallization process of calcium carbonate and produce aragonite scale. The presence of Zn〓 can prevent the formation of the crystal nucleus of calcium carbonate and then prevent the scale.
