Abstract
Methods were investigated for securing containerized hazardous wastes in the field with spray-on or brush-on resins at ambient temperatures. Laboratory-scale, cylindrical specimens of containerized sodium chloride (which simulated soluble salts containing heavy metals) were fabricated 63.5 mm in diameter by 88.9 mm high (2.5 by 3.5 in.). The salt was confined in fiberglass-reinforced, thermosetting resin casings and then sealed with a water-based polyurethane to provide a tough exterior jacket that would protect the contents from leaching and mechanical stress. The specimens exhibited functional stiffness and kept their contents stable when subjected to leaching stresses. The exterior jackets did not fail when specimens were compressed to about 80% of their original heights. Under heavy compression, however, the jackets ruptured where they were thinnest. Several coatings were needed to produce sufficiently thick, tough jackets. This report is a companion to two other documents on the use of plastics to encapsulate corroding hazardous waste containers: Securing Containerized Hazardous Wastes with Polyethylene and Fiberglass Encapsulates and Securing Containerized Hazardous Wastes with Welded Polyethylene Encapsulates PB81-231292.
