Influence of catalysts on the burning rate of nitrocellulose

摘要

Nitrocellulose is an essential part of single- and double-based propellants. But some questions remains in the catalysis of nitrocellulose. It is known that for the catalysis of double-based propallant carbon frame is needed. It can be formed from nitrocellulose in the low-calorie propallants or when we add carbon to the composition of propellant. In this work influence of carbon materials and some catalysts on the nitrocellulose with various content of nitrogen is investigated. It is shown that the higher the content of nitrogen (from 12 to 13.5%), the harder to catalyze the nitrocellulose. Some efficient catalysts show no result on the burning rate of the nitrocellulose.
