Abstract

The invention provides a clean heat and gas generation agent which comprises 30-50% of fuel, 50-70% of an oxidizing agent, 0-2% of a catalyst and 0-2% of a process additive. The fuel is guanidine nitrate, the oxidizing agent is ammonium nitrate or modified ammonium nitrate, the catalyst is one or combination of copper oxide, or copper chromite or potassium perchlorate, and the process additive is one or combination of kaolin, or clay or silicon nitride. The clean heat and gas generation agent has extremely high safety, it is extremely difficult to generate a chemical reaction under normal pressure, the clean heat and gas generation agent can be triggered through electrical signals under high pressure, and the clean heat and gas generation agent has the advantages of being safe, stable, high in heat generation, high in gas generation rate, clean in gas ingredient, few in residues, free of toxin and harm, high in cost performance and the like.

Description

technical field [0001] The invention relates to the field of heat generating and gas generating materials, in particular, the invention relates to a clean and efficient heat generating and gas generating agent suitable for a heater of a carbon dioxide extractor and a manufacturing method thereof. Background technique [0002] The carbon dioxide extractor is composed of a high-strength metal tube that can be refilled with liquid carbon dioxide, a heater (heating device), a filling mechanism, and a constant pressure energy release mechanism. Put the extractor in the coal borehole, use the detonator to start the heater, heat and pressurize the internal liquid carbon dioxide, and the pressure in the pipeline continues to increase to press the constant pressure energy release mechanism, causing the constant pressure energy release sheet to rupture , releasing carbon dioxide gas with a volume enlarged by 600 times and a pressure exceeding 100 MPa for blasting and dropping coal.
