Description

Forest fire extinguishing sub-bomb technology

technical field

The invention relates to the technical field of fire-extinguishing sub-munitions, in particular to forest fire-extinguishing sub-munitions technology.

Background technique

Fire-fighting bombs are fire-extinguishing devices used to reduce the fire. Fire-extinguishing bombs are mainly divided into two categories: sand and stone fire-extinguishing bombs and dry powder fire-extinguishing bombs. Fire-extinguishing bombs are easy to use and have great power, but if they are improperly operated, they will fail to detonate and lose their due In particular, the existing fire-fighting bombs on the market are mixed, and the quality is different. Some fire-fighting bombs made of ordinary ABC dry powder not only have low fire-extinguishing efficiency, but also have inherent properties such as moisture absorption and agglomeration. The defect of fire extinguishing bombs is that after a certain period of time, the proportion of "dud bombs" is very large, which not only affects the fire extinguishing, but also leaves hidden safety hazards.
