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/60 Shear rate (1/s) :Vs=Vs=Vu/ds
Unit of energy input = Energy/Total volume of input d = 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 dispersion chamber, 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 speed disperser is particularly important at a certain speed, If you want a more appropriate particle size, other factors and parameters will be even more important.
