分散乳化原理

影响分散的主要参?

转子圆周线速度(m/s):Vu=π×d×n/60剪切速率?/s(/span>:Vs=Vs=Vu/ds

单位能量输入=所输入能量/总体?/span>


d=转子直径(m (/span>

n=转子转速(1/min(/span>
ds=定转子间距(m(/span>


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'/span>m(/span>
n = Rotor speed'/span>1/min(/span>
ds = Rotor pitch'/span>m(/span>



影响分散结果的因素:

-工作形式(批次式或连续式(/span>

-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(/span>-物料在分散腔的滞留时间、分散时闳div>

-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、/span>


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.
