The surface appearance and hygroscopicity of ADN after coating were analyzed by SEM and weighing method. Results show that a kind of floccule of PU is formed on the surface of ADN, which makes the hygroscopicity of ADN after coating less than that before coating evidently. When coated ADN is exposed in the atmosphere for 30 days with the RH less than 60%, the hygroscopicity of coated ADN is only 0.136% and does not increase with the increasing of exposure time.

用扫描电镜和称重法分析了包覆后ADN的表面形貌和吸湿性，结果表明，聚氨酯黏合剂在ADN表面形成絮状的包覆膜，使包覆后ADN的吸湿率明显小于包覆前ADN，在相对湿度60%以下，包覆后ADN在空气中暴露30天时吸湿率仅0.136%，吸湿率不随时间增加。
