Investigation on Sedimentation and Stability Properties of Nanofluids with Submerged Arc Nanoparticles Synthesis System

Nanofluid has good suspension stability which may guarantee unique material characteristics and the application value of Nano-sericite in the industrial application.This study aims to use the self-developed Submerged Arc Nanofluid Synthesis System to produce nanofluid,which discusses sedimentation behaviors and suspension stability of nanofluid.In the article will analyze the influence of suspension stability which used mainly parameters of this system to synthesize Cu and Ti nanofluid,such as peak current,breakdown voltage and pulse-duration and so on.To utilize fabricate nanofluid to examine its average particle diameter,size distribution,observe the morphology of the particles,the pH value,Zeta potential,sedimentation behaviors of nanofluid and the composition,simultaneously observes and measures a period of time to find the correlation of above-mentioned characteristic of nanofluid changes.By way of long time measuring sedimentation behaviors and the suspension changes of nanofluid to confirm the suspension stability of fabrication nanofluid which purpose of Submerged Arc Nanoparticles Synthesis System under the different system regulation parameter condition.
