Abstract

The invention discloses an exothermic compound for liquid-gas phase change of carbon dioxide. The exothermic compound comprises the following components of: in parts by weight, 50-75 parts of potassium perchlorate, 15-25 parts of ammonium oxalate and 10-20 parts of salicylic acid. The exothermic compound does not burn or explode under the conditions of normal temperature and pressure, and has qualified impact sensitivity, friction sensitivity, flame sensitivity and electrostatic sensitivity; the exothermic compound burns to produce heat when excitation is performed under pressure of 4 MPa or above, and is safe and reliable.

Description

technical field [0001] The invention relates to the field of blasting materials, in particular to a carbon dioxide liquid-gas phase change heating agent. Background technique [0002] The carbon dioxide cracker uses liquid carbon dioxide to heat and gasify and expand, and quickly releases high-pressure gas to break rocks or fall coal. It solves the defects of explosive blasting mining in the past, large destructive and high-risk ore body crushing in pre-cracking, and contributes to mine safety. It provides reliable guarantee for mining and pre-splitting, and is generally applicable to operations in coal mines and non-coal mines. Carbon dioxide blasting has the advantages of low noise, small vibration, safety and environmental protection, and is widely used in various mining operations. [0003] The heating agent used in traditional carbon dioxide cracking equipment has a slow heating rate and small calorific value, which is difficult to meet the working needs of carbon diox...
