研究了室温硫化硅橡胶（SIR）在酸、碱和盐水溶液中浸泡后表面疏水性的损失随浸泡时间和浓度的变化。疏水性的损失和恢复与溶质和水在浸没期间的吸收及其随后在空气中的解吸相关。通过测量蒸馏水液滴的切线与水平RTV-SIR涂层表面之间的静态接触角来确定疏水性。在溶液中浸泡RTV-SIR涂层之前和之后，测量溶液的表面张力。这些值显示了溶液对RTV-SIR涂层的影响。
The loss of surface hydrophobicity of room temperature vulcanized (RTV) silicone rubber (SIR) due to immersion in acid, alkali and saline solutions has been studied as a function of immersion time and concentration. The loss and recovery of the hydrophobicity is correlated with the solute and the absorption of water during immersion and its subsequent desorption in air. The hydrophobicity is determined by measuring the static contact angle between the tangent to a droplet of distilled water and the horizontal RTV-SIR coating surface. The surface tensions of solutions were measured before and after the RTV-SIR coatings were immersed in solutions. The values show the effect of solution on RTV-SIR coating.
