固体颗粒表面改性及其在推进剂领域中的应用研究

Surface modification of solid particles and its application in propellants fields

对推进剂组分中的氧化剂、燃料等固体颗粒进行表面改性处理,不仅能提高单组分的使用性能,也是提高推进剂力学性能、改善燃烧性能和推进剂工艺条件的重要途径.本文综述了固体颗粒表面改性的方法及表面改性后的表征,分析了包覆颗粒性能变化及其对推进剂性能的影响.

Surface modification for solid particles component such as oxidizers and fuels in a formula for propellant can not only improve usable properties of single component, but also can increase mechanical properties and improve combustion properties and technical conditions of propellant. The method of surface modification for solid particles and token of the modified solid particles are summarized, then change of coated particles properties and its influence on properties of propellant are analyzed in this paper.
