Problems solved by technology

Traditional welding methods such as manual arc welding, gas welding, and newly developed laser welding and electron beam welding, etc., cannot be performed conveniently anytime, anywhere due to limitations in welding energy, welding equipment, and welding processes.
It is precisely because of these limitations that traditional welding methods can no longer meet the requirements of emergency repairs on the battlefield and emergency rescue of civilian facilities.

Abstract

The invention relates to a welding rod containing waste propellants and a preparation method thereof. The welding rod is made from waste propellants, a thermit chemical agent, a slag-forming agent and a stabilizer by the following steps of: grinding, gelating, extrusion-molding and completely dissolving. The invention reduces the pressure of disposing the waste propellants, avoids waste of resources and provides a novel welding material which can be effectively applied to battlefield equipment emergency repair and civil facility rescue. The welding rod is convenient to carry, easy to operate and safe to use and has strong combustion controllability, the preparation process is simple, raw materials are easily obtained, and the welding rod is favorable for industrial production.

Description

technical field [0001] The invention relates to a welding rod containing waste propellant and a preparation method thereof. technical background [0002] There are a large number of waste propellants waiting to be destroyed or reused every year in countries all over the world. As early as the 1950s, western developed countries continued to explore and study the destruction technology and resource utilization technology of waste propellants. Among them, the resource utilization technology has been favored by all countries because of its low environmental pollution and high economic benefits. . The resource utilization technologies that have been developed so far include preparation of industrial explosives, recovery of various components, preparation of industrial chemical raw materials and many other aspects. my country has also done a lot of work in this field. However, there is still a big gap between the processing capacity of the current resource utilization technology...
