【摘要】 通过对不同碱液处理的稻秸表面接触角的测量和环境扫描电镜的观察得出:经过碱液处理后稻秸表面的润湿性得到改善,接触角均随处理时间的延长而降低。从稻秸表面微观特征上看,氨基钠和氢氧化钠处理效果较好,氢化钙不理想(稻草表层出现了大量的晶体物质)。压板检测稻草板力学性能的结果表明,用质量分数1%的NaNH2处理10min效果较好。更多还原

【Abstract】 Through observing contact angles of rice-straw by different alkalit reatment with ESEM.The wettability of the face of straw had improvement.From the face characters,different medicines differently treat the face of straw.The effects of NaNH2、NaOH are better,CaH2 is the worst.Because the face of straw has a great of crystal materials with CaH2.Through clamp examination rice-straw board mechanical properties.The result indicated that processes 10min with quality score 1% NaNH2 to be well.更多还原
