Problems solved by technology

[0004] At present, there are many kinds of heating devices for carbon dioxide extractors. The major aspects include chemical heating and physical heating, and the heating materials include electrode heating and chemical heating. However, these heating materials have one thing in common that they generate heat slowly. The heating energy is small, and the effect of instant and rapid heating cannot be achieved

Abstract

The invention relates to an anaerobic pressure-controlled heating agent, comprising the following components in percentage by mass: 30-60% of guanidine nitrate, 30-60% of basic copper nitrate, 2-10% of catalyst and 2-10% of oxidant. The anaerobic pressure-controlled heating agent can be used as a heating material for a carbon dioxide exploiter for a coal mine. The pharmaceutical formulation of the anaerobic pressure-controlled heating agent is simple, and easy to get; and the combustion speed is controllable, as well as is slow in air, and extremely fast in thin-oxygen or inert environments and even under a certain confining pressure, for example, the combustion speed can achieve 15-30 m / s in a liquid-state carbon dioxide airtight tube having a pressure of 7.0 MPa.

Description

technical field [0001] The invention relates to the field of heating materials, in particular, the invention relates to an anaerobic voltage-controlled heating agent and its application. Background technique [0002] Drilling and blasting is the main way of excavation in coal mine roadway excavation in my country and it will last for a long time. Due to the particularity of coal mines, when blasting underground, the high temperature and flames generated by traditional explosives during the blasting process pose a certain danger to the safety of coal mines, especially when blasting in high gas and outburst mines, it is very likely to cause Coal dust and gas explosions have brought great potential safety hazards to coal mines. At present, the blasting operations of most coal mines in our country use coal mine explosives for blasting, which is difficult to manage, requires more personnel, and is very dangerous. [0003] The carbon dioxide extractor is a new type of blasting e...
