用Malvern激光粒度仪测量液滴粒度的改进
A MODIFIED DISPERSING METHOD FOR LIQUID DROP MEASUREMENT WITH MARVERN PALVERN SIZE ANALYZER
【摘要】 选择了稳定水滴的合适的乳化剂浓度,提出了液滴测量中样品分散的新方法并改进了Malvern激光粒度仪.选用水一煤油体系,实验验证了改进后的粒度仪的精度和乳化剂浓度对液滴稳定性的影响.认为2%的Span80与石蜡能够长时间稳定水滴,粒度仪改进后有效地提高了测量精度.
【Abstract】 The suitable concentration of emulsifying agent for stabilizing water drops andan new dispersing method for measurement with a Malvern particle instrument were proposed.It was confirmed that 2% Span80 in paraffin can stabilize water drops dispersed in keroseneduring a long time. The modified particle instrument can increase the precision of measurementof liquid drops distribution.
