Study of Particulate Fouling Inhibition Characteristics on a Novel Composite Coating

Particulate fouling is a common in heat exchange equipment, it causes tube corrosion and increases flow resistance. the hidden danger of equipment requires high treatment costs. In this paper, novel Ni?P?TiO2 composite coating prepared on 316 stainless steel using electroless plating inhibition characteristics are studied dynamic monitoring experimental system. The results show that thermal resistance obviously lower than under same working conditions. With increase cooling water velocity inlet temperature, surface decreases, while, with particle concentration, increases. Based DLVO theory, found energy close to best for inhibiting particulate deposition, which can significantly inhibit deposition. Compared stainless-steel conventional plate exchanger, not only inhibits accumulation fouling, but also reduces adhesion strength fouling; additionally, easier strip off surface, realizes lasting efficient surface. research provide data reference design daily operation exchangers.
