Safe and efficient method for preparing emulsion matrix

Abstract

The invention discloses a safe and efficient method for preparing an emulsion matrix, which comprises the following steps: (1) preparing aqueous phase solution and oil phase solution respectively according to a process matching; and (2) conveying the aqueous phase solution and the oil phase solution into a static mixer to be mixed, preliminarily emulsifying the mixture, then conveying the mixture to an emulsifier to be finely emulsified, and obtaining the emulsion matrix after the fine emulsification is finished. The method is mainly characterized in that by connecting the static mixer in series at the front end of the mechanical stirring emulsifier, the preparation capacity of the emulsion matrix of a finished explosive production line can be improved to 3.5 to 7 t/h from 2 to 4 t/h, the preparation capacity of the emulsion matrix for mixing and charging emulsive explosive on site can be improved to 5 to 12 t/h from 3 to 5 t/h, simultaneously the production safety and the quality of the emulsion matrix are ensured, and the method is suitable for popularization and application in the technical transformation for improving the capacity of the emulsive explosive.

Description

technical field [0001] The invention relates to a processing method of semi-finished explosives, in particular to a safe and efficient preparation method of latex matrix. Background technique [0002] Emulsion explosives are water-in-oil (W / O) latex type water-resistant industrial explosives prepared by emulsification technology. A water-in-oil emulsion system with dispersed air cells or porous material. Due to the large and close contact area between the ammonium nitrate aqueous solution and the emulsifier and oil phase material, which is very close to the excimer structure, its detonation excitation, propagation and other explosive properties have ideal explosive characteristics, making it waterproof. It has the advantages of high storage stability, high explosion transmission reliability, and good explosion performance, and has been vigorously promoted and applied in national economic construction. [0003] However, in recent years, there have been many major explosion ...

Problems solved by technology

[0006] (1) Its colostrum is mechanically stirred, and the stirring efficiency is low, and because the amount of medicine stored in the colostrum container is usually greater than tens of liters (it is stated on the patent document that it is less than 120L), the safety is poor;

[0007] (2) When a static mixer is used for intensive milking, the shear strength of the latex particles is required to be high and the viscosity of the latex body is high, so a high-resistance static mixer must be selected, and the pressure loss of the material
