硅化合物阻燃增效EVA/Mg(OH)2复合材料
硅化合物 无卤阻燃 氢氧化镁 乙烯-醋酸乙烯酯共聚物
2011/10/25
随着高分子材料在国民生活中的广泛应用,它的阻燃问题备受人们关注。近几年,无卤阻燃技术成为阻燃研究的重点和方向。无卤阻燃技术通常是填充Mg(OH)2于高分子材料中。但Mg(OH)2阻燃效率低,填充量达到60wt%左右才具有优异的阻燃性来提高Mg(OH)2的阻燃效率,降低其填充量,挽救复合材料的力学性能。硅化合物是Mg(OH)2的一种较好的阻燃增效剂,有人认为,硅化合物能够改善Mg(OH)2的分散,加...

无机碳酸盐沉积的硼同位素分馏—B(OH)3掺入碳酸盐的证据
硼 同位素分馏 生物碳酸盐
2009/2/13
进行了高pH(8.96~9.34)海水的无机碳酸盐沉积实验, 测定了沉积碳酸盐的硼同位素分馏. 结果表明, 碳酸盐和海水B(OH)3间的硼同位素分馏系数(αcarb-3)变化范围是0.937~0.965, 平均值为0.953. 这些结果与Sanyal等报道的结果都表明碳酸盐与溶液B(OH)3间的硼同位素分馏系数αcarb-3 不是恒定的, 而是与溶液pH呈现负相关关系. 测定的碳酸盐沉积的硼同位素...
名义上无水矿物(NAMs)的结构水研究是认识超高压变质作用(UHPM)过程中流体活动规律的重要手段,并对板块汇聚边缘大陆动力学及水的深部地球循环有重要意义。本文采用傅立叶变换红外光谱(非偏振光)研究了中国大陆科学钻探(CCSD)主孔岩心及其周围地表榴辉岩中副矿物—金红石中的结构水。所有测试样品都在3285 cm~(-1)和3295 cm~(-1)附近产生尖锐的吸收峰,证实“水”以结构羟基(OH~-...
