摘要
固体浮力材料是一种低密度、高强度多孔结构材料。将聚氨酯弹性体喷涂在材料表面作为阻水层使用,能有效降低材料吸水率和体积变形率,对提高固体浮力材料水下使用安全性和可靠性具有重要意义。
Sold buoyancy material was a low density, high strength material with many holes. The water absorption and volume deformation ratio of the solid buoyancy material could effectively decreased by coating the PU elastomer used as anti--water layer material on it, and the technology had the importance for increasing the safety and reliability of the solid buoyancy material under water.
