Energy-saving and environment-friendly expanded ammonium nitrate explosive

Abstract

The invention discloses an energy-saving and environment-friendly expanded ammonium nitrate explosive, which is prepared from the following raw materials in parts by weight: 80.5 to 94.5 parts of expanded ammonium nitrate, 1.5 to 4.5 parts of oil phase, 2.5 to 5.5 parts of straw powder and 0 to 12 parts of salt, wherein the oil phase is diesel, motor oil or paraffin; and the straw powder is a solid hydrocarbon with a formula of C47H75O27. The energy-saving and environment-friendly expanded ammonium nitrate explosive is favorable for improving the level of environmental protection, energy saving and consumption reduction in the production of the explosive and is favorable for improving the level of safety production of the explosive and the explosive quality.

Description

technical field [0001] The invention belongs to industrial explosives, in particular to an energy-saving and environment-friendly expanded ammonium nitrate explosive. Background technique [0002] Currently, the main components of expanded ammonium nitrate explosives in China are expanded ammonium nitrate, oil phase and wood flour, etc. The oil phase materials can be diesel oil, engine oil, paraffin wax, microcrystalline wax, etc. The amount of wood powder is generally equivalent to that of the oil phase material. Because wood flour has the characteristics of high carbon and hydrogen content, large negative oxygen balance, low density, and many voids, it can adjust the looseness of the explosive system, reduce the agglomeration tendency and strength of powdered ammonium nitrate explosives, and has a sensitization effect. It can improve the sensitivity of the system, so wood powder plays multiple functions such as loosening agent, sensitizer, and combustible agent in powdered...

AI Technical Summary

Problems solved by technology

The above moisture absorption characteristics of wood powder not only greatly affect the storage performance of explosives, but also lead to high energy consumption in the drying process

[0006] Third, when wood powder is used in a continuous puffed explosive production line, it is prone to phenomena such as wood powder overhead and poor discharge, which seriously affects the accuracy of the proportion of explosive components and the explosive performance of explosives

And its density varies with the material and moisture content. Generally, the density of dry wood powder is about 0.4-0.6g / cm 3 , bulk density is 0.17~0.24g / cm 3 , wood flour produced from different materials has a great influence on the explosive performance of explosives, and at the same time, the expanded ammonium nitrate explosive produced with wood flour as raw material has a low density and has the defect of insufficient relative volume and power
