Problems solved by technology

By comparing the raw materials for the production of explosives, only ammonium nitrate has a better competitive advantage in terms of industrial cost and stability, but ammonium nitrate has a strong tendency to absorb heat and agglomerate, which not only affects the production, storage and application of explosive products, but also causes Reduced explosive performance, or even loss of usability

Abstract

The invention relates to a soluble modified ammonium nitrate fuel oil explosive and a method for preparing the same, which comprises 83%-90% of ammonium nitrate, 3%-7% of compound grease, 4%-12% of water, 1%-3% of sodium nitrate or sodium sulfate with finished product water content less than 0.5% by weight percentage. The aqueous phase and oil phase accordance with the ratio are heated and dissolved to keep temperature between 100 and 150 DEG C for standby, the prepared aqueous phase and oil phase are pumped by a pump body into a pipeline type mixer to mix after measurement by a flowmeter, the mixed aqueous phase and oil phase are dewatered, granulated and dried by means of gas atomization in the pipeline, the granulated material is charged and packed after cooling. The method of the invention adopts conventional ammonium nitrate fuel oil explosive formula and conventional airflow production process, introduces compound grease while modifying the ammonium nitrate by means of wet method-air flow drying, which makes the energy of the composite explosive fully developed, prepares high performance ammonium nitrate fuel oil explosive and reduces the cost of raw material and production to a maximum extent.

Description

technical field [0001] The invention belongs to ammonium nitrate explosive and a preparation method thereof, in particular to a dissolved modified ammonium oil explosive and a preparation method thereof. technical background [0002] The industrial explosives in foreign developed countries are mainly emulsion explosives and porous granular ammonium oil explosives. This is due to the specific open-pit mining decision. The mining methods in my country are mostly caverns or underground mining. Due to the specific operating environment, the critical diameter of the product is small. , high detonation sensitivity and explosive performance. The products used in the past few years all contain simple explosive TNT. This substance is a nitro compound, which has a serious impact on the physiological functions of the human body. People who have been exposed to it for a long time will be chronically poisoned, resulting in Blood system diseases; In recent years, the goal of eliminating lad...
