表面活性剂

Since there exists some disadvantages such as poor mechanic properties and much higher burning rate pressure exponents (?1) in the fundamental formulations, this work is devoted to the improvements of combustion characteristics and mechanic properties of LOVA propellants. The effects of the crystal shape, size and contents of nitroamine particles, the types of binder, plasticizer and surface-active agents and the contents of NC on combustion performance are studied by closed bomb tests. In the mechanic properties tests, the effects of the types of binders, plasticizers and solid fillers, the interaction between binders and solid fillers and technological procedures on propellant mechanic properties are researched.
