Effect of Pretreatment Temperature and Sodium Chloride Concentration on Energy Dissipation Characteristics of ZSM-5/Water System

Research and development of new materials with high energy dissipation density is of intriguing interest in protective engineering fields. With ultra-large specific surface area,nanoporous material enables a high-efficiency energy dissipation system by interaction with liquids,which has a promising application in vehicle crash safety and anti-explosion for armored vehicles. In this paper,ZSM-5 zeolite / NaCl solution system,a mixture with ZSM zeolite immersed in sodium chloride solution was experimentally investigated. Its energy dissipation characteristics and working mechanism were explored by quasi-static compression experiments. Effect of pretreatment temperature of ZSM-5 zeolite(600–1100℃) and NaCl concentration of the solution(0–2 mol/kg 2H O) were examined parametrically. Results show that the energy dissipation density of ZSM-5 zeolite / NaCl solution system can reach 12 J/g,as a reusable system under quasi-static loading. Its performance characteristics can be finely tuned by pretreatment of ZSM-5 and adding different concentrations of NaCl. The energy dissipation density increases with pretreatment temperature and decreases with NaCl concentration,while its working pressure increases with both of them. This work is of significance for the development of intelligent,controllable and efficient energy dissipation devices.
