对化学镀Ｎｉ－Ｐ－ＰＴＦＥ换热面进行了模拟循环冷却水中ＣａＣＯ３的结垢实验研究．结果表明，当换热面上有解吸空气泡时，该表面结垢较Ｃｕ面加剧；无解吸空气泡时，结垢减轻．并运用分形理论对结垢行为进行了评价，发现化学镀表面垢形之分维值较Ｃｕ面的增大了．
The scaling experiment of CaCO3 in simulated circulating cooling water was carried out on electroless Ni-P-PTFE heat transfer surface. The results show that when desorption of air bubbles on the heat transfer surface, the surface fouling worse than Cu surface; The fractal theory was used to evaluate the scaling behavior. It was found that the fractal dimension of the electroless plating surface increased more than the Cu surface.
