Abstract

Sea-spray ice accretion poses a major problem in the operation of lighthouses in northern harbors. To address this problem, we designed membrane structures, by using a combination of surface treatment and deformation of film material. In this study, adhesion strength tests of pure ice and saline ice were carried out using polymer-films and fabric materials. In the results for pure ice, a marginal difference was observed between the adhesion strengths of waterproofed nylon, polyu-rethane-coated polyester, and fluoroethylene plastic at-5°C. The adhesion strengths of most of the samples exhibited an increasing tendency with a decrease in temperature from-5°Cto-25°C. On the other hand, fluoroethylene plastic, a water-repellent coating material low adhesion strength even low temperatures. In the results saline water, the adhesion strength of the super-hydrophilic film almost decreased to 0 with the salinity.
