Problems solved by technology

There are many disadvantages in this way. 1. Larger powder particles are prone to friction and generate static electricity during the vaporization of liquid oxygen.
2. Paper medicine packs are not conducive to static electricity export
3. When the production is completed and moved to the blasting point, it is easy to be exposed to external open flames and mechanical impacts, resulting in the risk of accidental explosion

Abstract

The invention discloses a liquid oxygen explosive composite and liquid oxygen explosive, belonging to the technical field of liquid oxygen explosive materials containing fuel and enough oxidants to generate high-speed chemical changes after being exploded to generate substances used for detonation. A liquid oxygen explosive composite comprises liquid oxygen and a combustible, wherein the combustible is composed of 50-70% by mass of pulverized coal and 30-50% by mass of wet sawdust or combustible fiber, and the wet sawdust is prepared by humidifying sawdust to 5% by using a sodium chloride solution with concentration of 20%. The liquid oxygen explosive composite and liquid oxygen explosive disclosed by the invention have the advantages of preventing generation of static electricity and explosion possibility, reducing the explosive sensitivity and ensuring the explosive to be safer.

Description

technical field [0001] The invention belongs to the technical field of substances containing fuel and sufficient oxidizer, producing high-speed chemical changes after detonation, and producing high-speed detonation waves that can be used for blasting. Specifically relates to a liquid oxygen explosive composition and liquid oxygen explosive. Background technique [0002] The explosive made by mixing combustible porous substance and substance with high carbon content as absorbent and saturated with liquid oxygen is called liquid oxygen explosive. Liquid oxygen explosives produce a variety of explosive effects, which mainly depend on the following factors: the type and density of the absorbent, the size of the fibers (for brick-like absorbents), the degree of comminution (for powder-like absorbents) ), and the content of liquid oxygen in the explosive mixture at the time of explosion. [0003] The principle of liquid oxygen explosive explosion is the same as that of ordinary ...
