Toluene/Glycerin분산계에서 Toluene의 액적입도가 계의 상대점도에 미치는 영향
Effect of Drop Size of Toluene on the Relative Viscosity in the Toluene-Glycerin Dispersion
초록
Toluene/Glycerin분산계에서 분산상인 toluene의 액적입도분포가 분산계의 상대점도에 미치는 영향을 고려하기 위하여 Oldroyd의 상대점도식으로부터 분산상의 액적입도분포를 고려한 상대점도식을 얻었다.
분산상인 toluene의 부피농도가 5 %에서 25 %인 분산계의 상대점도 실험결과로부터 toluene/glycerin계면에서의 점도특성치가 1.696 cp·cm, 실험치와 유도된 식의 사이에 최소오차 0.24 %, 최대오차 2.06 %, 평균오차 1.109 %인 것을 얻을 수 있었다.

The successive application of Oldroyd's equation of relative viscosity to tolulene-glycerin dispersion system leads to a equation, expressing the functional relationship among the relative viscosity of the dispersion, volume concentration and drop size distribution.
The experimental results of the toluene-glycerin dispersions from 5 % to 25 % of the volume of toluene were tested against the derived equation. The viscosity property of the interface was 1.696 cp·cm. And the errors between experimental viscosities and the values calculated by the proposed model ranged from 0.24 % to 2.06 %. The average error percentage was 1.109 % and the maximum error percentage for the system was 2.06 %.
