MICRO-GAS GENERATION

摘要

A gas generant composition used in pressure activated restraint system devices such as micro-gas generator applications such as seat belt pretensioners is provided. The gas generant composition includes a potassium perchlorate gas generant additive in addition to a non-azide nitrogen-containing gas generating fuel, a metal ammine nitrate oxidizer, and a metal oxide burn rate enhancing and slag formation additive. The gas generant composition desirably has improved ignitability as compared to a similar composition without the potassium perchlorate gas generant additive. The gas generant composition also desirably produces or results in effluents having either or both reduced carbon monoxide and NOX contents as compared to the effluent produced or resulting from a similar composition but without the inclusion of the potassium perchlorate gas generant additive.
