Effects of Discontinuous Thermal Conductivity of a Substrate Surface on Ice Adhesion Strength

This study proposes a novel anti-icing model in which silicone rubber with low thermal conductivity is coated at different positions on material surface to change the continuity of surface. During test, surfaces aluminum alloy and polymethyl methacrylate (PMMA) are discontinuously rubber. Repeated experiments conducted verify effect proposed model. Results showed that compared conventional ice adhesion strength, rate reduction strength PMMA could reach 75.07% 76.70%, respectively, when method used. Because levels surface, water attached locations without had other freezing times. Combined heat phase during process, changing stability interface between substrate act as an active power. The then be reduced. Compared methods, this significantly increase characteristics provide for use engineering applications.
