Embodiment Construction

[0016] A method for increasing the density and performance of continuous expanded ammonium nitrate explosives of the present invention will be further described below in conjunction with the accompanying drawings and specific examples.

[0017] as attached figure 1 As shown, the main formula of the expanded ammonium nitrate explosive includes ammonium nitrate (A), oil phase material (B), wood powder (C), oil phase material (D), wherein (D) accounts for (A) The weight ratio is 0.10 ~0.20%. The method to optimize the internal quality and performance of the product is to add oil phase materials in the process of preparing expanded ammonium nitrate. The specific steps are as follows. First, configure the oil phase material (D) according to the composition ratio in Table 1; Add oil phase material (D), then add expansion agent, carry out vacuum expansion crystallization; Then carry out three material mixing according to the explosive composition ratio in Table 4, obtain product aft...

Abstract

The invention provides a method for improving the density and the properties of continuously-expanded ammonium nitrate explosive. The rock expanded ammonium nitrate explosive mainly comprises the following components of ammonium nitrate (A), an oil-phase compound material (B), wood powder (C) and an oil-phase material (D), wherein the weight proportion of (D) in (A) is 0.10-0.20 percent. The gap distance is improved by more than 1 cm. Furthermore, the expanded ammonium nitrate is prevented from being caked by the ammonium nitrate and the dust is reduced.

Description

technical field [0001] The utility model relates to the field of industrial explosive production, in particular to a method for improving the density and performance of continuous expanded ammonium nitrate explosive. Background technique [0002] At present, the formula used in the production of rock expanded ammonium nitrate explosives in China mainly includes expanded ammonium nitrate, composite oil phase materials, and wood powder. During the production process of expanded ammonium nitrate explosives, the three materials are mechanically mixed according to a certain ratio. After the continuous process cancels the wheel mill mixing process, the expanded ammonium nitrate explosive has a low density. [0003] In view of these problems existing in the continuous expanded ammonium nitrate explosive product, it becomes particularly urgent to seek an effective method that can improve the density and performance of the explosive without affecting the performance of the expanded a...
