摘要
Abstract
A new experiment was designed to investigate microbial fouling characteristics on heat exchanger of electroless plating of Ni-P. In this paper,the surface of low-carbon steel sheet,which is common for heat exchanger,was modified by using the method of electroless Ni-P and low-carbon steels before and after electroless Ni-P,and pictures were taken by scanning electron microscopy. A comparative experiment was designed to investigate microbial fouling characteristics of low-carbon steel sheet and low-carbon steel sheet with electroless plating of Ni-P. Slime-forming bacteria that was isolated and purified from Songhua River is chosen as the strains. The changes of fouling were recorded by the method of weighing,and the changes of bacterial counts were recorded by the method of optical turbidity. The results of the experimental show that the surface morphology of electroless plating of Ni-P is better than that of low-carbon steel after the low-carbon steel sheet was electroless plated. For the corrosion caused by slime-forming bacteria,the corrosion resistance of electroless plating of Ni-P is better than that of low-carbon steel sheet and the anti-microbial fouling of electroless plating of Ni-P is preferred. When the slime-forming bacteria grew and reproduced vigorously and metabolites were excessive,biofouling was formed soon; in contrast,biofouling was formed slowly.关键词
