中文摘要: 在一定工艺条件下,研究了添加剂1,2-辛二醇对铝酸钠溶液种分产品强度和形貌的影响。结果表明,添加剂1,2-辛二醇的加入能明显抑制铝酸钠溶液的分解(分解初期),同时加入添加剂后铝酸钠溶液种分生成了很多小晶体,这些小晶体或填充在晶粒缺口处;或镶嵌成大颗粒,且大颗粒之间有充当粘结剂的更细的晶粒填充,明显改善了产品的强度。
Abstract:With the addition of surfactant 1,2-Octanediol,the strength and morphology of Al(OH)3 products precipitated from sodium aluminate solution have been investigated on certain process conditions.The results show that 1,2-Octanediol has strong inhibitory effect on gibbsite precipitation from seeded sodium aluminate liquor(during the early stage of the precipitation),many small crystals were generated with the addition of 1,2-Octanediol.Some of these small crystals were filled in the notch of crystal grains,othe...
