SURFACE CHEMICAL METHODS OF DISPLACING WATER AND/OR OILS IN SALVAGING FLOODED EQUIPMENT. PART 1. PRACTICAL APPLICATIONS
Abstract
The effectiveness of surface-active substances in displacing Navy Special fuel oil and water from solid surfaces has been demonstrated. A general mechanism is outlined for the rapid displacement of one liquid by another as a result of unbalanced SURFACE FORCES. Two formulations have been developed, one for the displacement of fuel oil and the other for the removal of water from electrical, electronic, or mechanical equipment. Both formulations are relatively harmless to most electrical and electronic insulation. The fuel oil- cleaning emulsion retards rusting of the ferrous metals with which it comes in contact, while the water-displacing composition leaves a persistent and effective rust inhibiting film over the surfaces of the equipment. Electrical and electronic components which had been submerged in a mixture of Navy Special fuel oil and sea water were effectively salvaged by treatment with the fuel-oil- cleaning emulsion and the water-displacing composition. An integrated procedure is outlined for the recovery of electrical, electronic, or mechanical equipment after such submersion. A method of sealing the insulated parts of electromotive equipment against penetration of flooding water is also presented.
