Behaviour of absorbent particle between electrodes for applying electric field in oil (Effect of quantity of absorbed water on behaviour of particle)

An experimental study has been carried out to clarify the effect of quantity of absorbed water on behaviour of single silica-gel particles in oil with dc electric field, as a basic research to augment adsorption. The progress of adsorption changes mass and physical properties of a silica-gel particl...

description An experimental study has been carried out to clarify the effect of quantity of absorbed water on behaviour of single silica-gel particles in oil with dc electric field, as a basic research to augment adsorption. The progress of adsorption changes mass and physical properties of a silica-gel particle, and the change might influence the behaviour of the particle. The experiment is conducted under condition that the adsorbed material is only water, and the quantity of water is adjusted beforehand to prescribed value. Two electrode plates are horizontally set up 40 mm apart in silicone oil. Particle diameter is adopted of 2.7, 4.0 and 5.0 mm, and the range of applied voltage is 0 - 28 kV. The applied voltage is increased at approximately 2kV/min. Observation of behaviour of a silica-gel particle starts from resting condition on a lower electrode. As a result, a dried silica-gel particle does not begin moving even at the maximum voltage. For a silica-gel particle of water adsorbed, following four stages have been observed, excluding a very few exceptions; rise from the upper side of lower electrode to the upper electrode, bound and rest on the lower side of the upper electrode, descent to the lower electrode, and bound and rest on the lower electrode. The rest time on the electrode is not seen to a completely water-absorbed silica-gel particle. It is thought that the particle exchange the electric charge at the rest time. The applied voltage for the leave of a silica-gel particle from the lower electrode, rest time on each electrode, and bound height from each electrode are also shown.
