In this paper, three kinds of explosion-suppression materials including aluminum alloy, polyurethane foam and spherical polymer are measured to get the data of displacement ratio and retention ratio, which can be used to calculate the reduction ratio of effective volume of the oil tank. The results show that the displacement ratio of the three kinds of materials are respectively 2.0%, 2.5% and 5.2%, the retention ratio are respectively 1.1%, 3.2% and 0.4% and the reduction ratio of effective volume are respectively 3.1%, 5.7% and 5.6%. Meanwhile, the cook-off properties of the oil tank filled with spherical high molecular explosion-suppression materials were tested, the methanol in the tank didn’t explode, and materials in the tank didn’t deform and be destroyed during the experiments. All of the results showed that the spherical high molecular explosion-suppression materials presented a good explosion-suppression performance.
Key words: explosion-suppression materials / reduction ratio of effective volume / cook-off properties / explosion-suppression performance
