影响分散的主要参数:
转子圆周线速度(m/s):vu=π×d×n/60剪切速率(1/s):vs=vs=vu/ds
单位能量输入=所输入能量/总体积
d=转子直径(m)
n=转子转速(1/min)
ds=定转子间距(m)
the main impact of dispersion parameters:
rotor peripheral speed (m/s) : vu =π×d×n/60shear rate (1/s) :vs=vs=vu/ds
unit of energy input = energy/total volume of inputd = rotor diameter(m)
n = rotor speed(1/min)
ds = rotor pitch(m)
影响分散结果的因素:
-工作形式(批次式或连续式)
-工作头的剪切速率
-工作头的齿形结构(如粗齿、中齿、细齿、超细齿)-物料在分散腔的滞留时间、分散时间
-循环次数
dispersion factors influence the results:
-forms of work (batch or continuous)
-working head of the shear rate
-work head tooth structure (such as coarse teeth,the teeth, a fine-tooth, ultra-fine tooth)
-residence time of the material in the dispersionchamber, the dispersion time
-cycles
在乳液分散的过程中,分散机的线速度尤为重要,在一定的线速度下,如果想得到更合适的粒径,其他的影响因素与参数则会显得更重要。
in emulsion dispersion process, the line speeddisperser is particularly important at a certainspeed, if you want amore appropriate particle size,other factors and parameters will be even moreimportant.
