Technology study of modified nitrate pyrotechnic safety oxidant
Abstract
The thesis aimed to create a safe,inexpensive and highly reactive pyrotechnic oxidants.This article first through the production process of composite nitrate,and the process of product density measurement, moisture detection,electron microscope analysis,thermal analysis and detection of firecracker application performance and other aspects of the evaluation,and explores barium carbonate powders produced composite nitrate.Finally can completely replace the potassium perchlorate in application performance,density reduced composite nitrate,high safety and good resistance to moisture.Factors affecting the preparation process,puffing agent 10% can be good extrusion and moistureproof effect,10% potassium nitrate proportion will not affect nitrate puffing will also improve the activity of the products,the catalyst suitable and adding have positive influence on activity of the products produced.Through the evaluation of experimental exploration and the application performance,a new safe and cheap oxidant formula was successfully created.
