The rates of nucleating and nuclei growing were measured under various experimental conditions. The experimental results showed that both nucleating and nuclei growing rates of CaCO3 increased obviously with surface temperature and concentration of reagents. In addition, the experiment of fouling induction period on the surface material of chemical plated nickel-phosphorus-polytetrafluoroethylene indicated that not only the nucleate rate of CaCO3 decreased but also some fouling particles with certain size were easy to peel off from the heated surface under shearing stress, which means that the property of surface material is one of the most important factors influencing fouling induction periods.展开更多
