Abstract Segregation of components, especially the low content level of a highly active substance, has serious deleterious effects on powder formulation. This study investigates the effect of particle properties, particularly size, shape, density and cohesion, on the segregation of laundry detergent powders. Tetraacetylethylenediamine (TAED) particles, spray-dried synthetic detergent powder referred to as Blown Powder (BP) and Enzyme Placebo Granules (EP granules) are used as a model formulation. The segregation of components is evaluated using image processing of the photographic records taken from the front face of a two-dimensional heap of powders. Coefficient of variation concept is considered as segregation index. It is shown that EP granules, the component used as low-level ingredient (

颗粒性质对三元粉末混合物离析影响的实验评价

摘要 成分偏析,特别是高活性物质含量偏低,对粉体配方产生严重的不利影响。本研究调查了颗粒特性,特别是尺寸、形状、密度和内聚力,对洗衣粉分离的影响。四乙酰乙二胺 (TAED) 颗粒、称为吹制粉末 (BP) 的喷雾干燥合成洗涤剂粉末和酶安慰剂颗粒 (EP 颗粒) 用作模型配方。使用从二维粉末堆正面拍摄的照片记录的图像处理来评估组分的分离。变异系数概念被认为是分离指数。结果表明,EP颗粒作为低含量成分使用的成分(
