Problems solved by technology

[0005] The exothermic agent used in the existing carbon dioxide phase change fracturing equipment on the market has a slow heating rate and a small calorific value, which is difficult to meet the needs of carbon dioxide phase change fracturing and affects the normal operation of the carbon dioxide fracturing device
In addition, the flame sensitivity, impact sensitivity, friction sensitivity, and static electricity sensitivity of some heating agents are too high, which brings great safety hazards to production, transportation, storage, and use.

Embodiment 1

[0022] The various solid powders of 200 mesh to 400 mesh are: 15% calcium perchlorate, 45% sodium nitrate, 14% starch, 4% sodium dodecylbenzenesulfonate, 4% boxwood powder, Dry process wood fiber 5%, CaF 2 5% aluminum powder, 5% phenolic resin and 3% phenolic resin are mixed evenly and then filled in a sealed container with an electronic ignition head inside, and then the sealed container is fixed in the blasting tube for electronic ignition. The results show that the exothermic agent can convert liquid carbon dioxide into gaseous carbon dioxide within 0.2s at the ignition temperature of 1200°C to 1400°C, completing the explosion.

Abstract

The invention provides an exothermic compound for a carbon dioxide gas blaster. The exothermic compound for the carbon dioxide gas blaster is prepared from, by mass, 10%-20% of perchlorate, 35%-55% of nitrate, 8%-15% of combustible, 3%-5% of sodium dodecyl benzene sulfonate, 3%-5% of boxwood powder, 4%-6% of dry method wood fibers, 3%-5% of CaF2, 4%-6% of aluminum powder and 2%-4% of phenolic resin. The combustible is selected from one or more of saccharose, glucose, starch and cellulose. The exothermic compound for the carbon dioxide gas blaster has the advantages of being fast in heating and large in heat value, is low in flame sensitivity, percussion sensitivity, friction sensitivity and static sensitivity, can eliminate potential safety hazards well, and provides convenience for production, transportation, storage and use.

Description

technical field [0001] The invention relates to the field of civil blasting technical equipment, in particular to a heating agent for a carbon dioxide gas blaster. Background technique [0002] Traditional civilian blasting mostly uses high-risk explosives such as detonators, TNT, black powder, nitroglycerin, and RDX. Because such explosives are highly dangerous and difficult to control, they cause huge losses to the national economy and social families every year, and the harm is huge . In addition, in areas such as urban residential areas and high-gas coal mines, the uncontrollability of traditional explosives has brought huge difficulties to installation and use. In addition, traditional explosives are characterized by high difficulty and high risk in production, transportation, storage, and management. [0003] In order to solve the high-risk problems of traditional explosives, carbon dioxide phase change fracturing technology appeared in the 1950s, and this technology...
