Experimental Investigation of the Effect of Emulsifier Concentration on the Properties of Olechemical Oil Based Cutting Fluid

Experimental investigation of the effect of emulsifier concentration on the properties of olechemical-oil -based cutting fluid was studied. It was observed that as the emulsifier concentration increases from 2% to 8%, the kinematic viscosity increased. However, for emulsifier concentration of 10%, the kinematic viscosity started decreasing for all the temperature range used, although an increase was observed with increase in temperature. On the other hand, other properties such as thermal conductivity, pH value, flash and fire points increased as the concentration of the emulsifier was raised. However, microbial growth decreased as the pH value increased.
