Problems solved by technology

[0005] The heating element of the above-mentioned patent has insufficient heat, and it is relatively difficult to initiate heat release. At the same time, the oxygen release rate is slow, and the ignition performance at low temperature -40°C does not ignite, and the main oxygen column cannot be ignited or cannot continue to be ignited at room temperature.

Abstract

An ignition medicine with chlorate oxygen column and its production are disclosed. The ignition medicine consists of sodium chlorate 30~50% with grain size 60~300 meshes, lithium hyperchlorate or sodium perchlorate 10~30% with grain size 60~300 meshes, barium dioxide 0.1~6% with grain size 80~200 meshes, metal oxide ironic oxide or cuprous oxide 5~9% with grain size 20~200 meshes, metal powders 15~25% with grain size 100~300 meshes and cobalt salt 5~15% with grain size 40~200 meshes. It has shorter gas-take time and higher starting success probability of engine.

Description

technical field [0001] The invention relates to a chlorate oxygen column igniter and a preparation process thereof. technical background [0002] The solid chemical oxygen generator is a solid chemical oxygen generating device, which is mainly composed of oxygen generator-oxygen column, thermal insulation system, filtration conversion system and shell. To make the oxygen column undergo a chemical reaction to release oxygen, it must be ignited by the ignition system, which involves the development of the formula of the igniter. Because the oxygen column used for oxygen gas generating agent is an inorganic solid powder column composed of chlorate as the main body and various additives and catalysts. It is formed by compression molding, has a high density, and has a smooth and hard surface, poor flammability, and is difficult to ignite directly. , In the case of low temperature, there is often the problem that the igniter cannot be ignited or the main oxygen column cannot be i...
