Abstract:

Work performed under this contract represents the first practical development of a process and equipment for producing large quantities of rigid sulphur foam. It was demonstrated that foamed sulphur can indeed be produced on a continuous basis at a remote field site by a process and with equipment that is simple and capable of being scaled up to any size. The foam prepared using the procedures and equipment developed here in has mechanical properties comparable to that produced on a batch basis in the preceding laboratory study-- namely a density of 27 lbcubic ft, a compressive strength of 130 psi, a constant strain rate deformation to 65-70 percent, and a low water absorption. Since the cost of the raw materials for these sulphur foams is less than two cents per pound, a foam with a density of 27 lbcu ft can be produced for only 0.54 per cubic foot. Conventional foams with similar physical properties that can be produced at a remote field site are the rigid urethane foams. The comparative cost of a urethane foam having a compressive strength of 125 psi is approximately 3.00 per cubic foot. During the week of 17 January 1965, the feasibility of producing foamed sulphur in the field was demonstrated for the Air Force at Kirtland Air Force Base, Albuquerque, New Mexico, by filling a 30- cubic foot annular space with rigid foamed sulphur.
