Abstract

This study reports the effect of adding silver sulfide to mineral oil and mixed fluid on their static electrification and visco-elastic properties. The flow electrification studies indicate an increase in streaming current for higher silver sulfide concentration with the hysteresis pattern indicating a higher current during the decrement of disc velocity. The transition from loss modulus to storage modulus was visible in the mixed fluid compared to mineral oil. Further, the effect of silver sulfide has reduced the storage modulus with frequency sweep and temperature sweep testing on both mineral oil and mixed fluid.
