The fluid magnetic abrasive (FMA) is a new type of precision finishing abrasives which is a sort of suspended fluid composed by magnetic particles, nonmagnetic abrasive particles, surfactants in a non-magnetizable carrier liquid. This paper is to solve the contradiction of disperser stability by adding the surface active agent (dispersing agent), the nano- particles etc.

Conductive Properties

The influences of the oxidative modification, coupling treatment and dispersing agent for carbon fiber dispersion and binding properties were investigated, and the relationships of different ratio of carbon fiber with the physical strength and electrical conductivity of the paper were analyzed. Meanwhile fiber surface morphology, zeta potential and absorbance slurry were tested. The result showed that: coupling modification significantly improved the dispersion performance of carbon fiber, superior than oxidative modification, the increase of the dispersion would enhance the conductivity of carbon fiber network, the effect of CPAM was best in four kinds of surface-active agent, and 30% content of carbon fiber achieved the "percolation threshold” of conductive material.

The Stability

Craik (1968) has previously examined the stability of horizontal liquid films when an air stream flows over the liquid surface and when the surface is contaminated by an insoluble surface-active agent. The present theoretical work extends this investigation to examine the role of soluble surface-active agents for cases where the liquid Reynolds number is small. This role is found to be a rather complex one which, under suitable conditions, may be either stabilizing or destabilizing.Related experimental work is described which yields results in qualitative agreement with the theoretical analysis.

Surface Active

Nonionic surface active agent AO-1, n-butanol, kerosene and water were mixed in varying proportions to compound micro-emulsion. According to different phase states of each micro-emulsion, some systems with representative were picked up, and then tested the interface properties of oil phase of the systems above. The experimental results show that there is a system with low interfacial tension and steady surface tension.
