A method for sweating and producing insensitive wax for explosives

Abstract

The invention discloses a method for sweating and producing deterred wax for explosive. The method is based on common sweating and de-oiling processes, in a sweating process, air-flow passes through a wax layer for carrying liquid state oil in order to compulsively separate wax and oil; at the same time, a solid weight is placed on the wax layer in order to exert pressure intensity to the wax layer for accelerating separating speed of wax and oil and ensuring passing of the air-flow through the wax layer, and the sweating and deoiling solvent-free method can be used for producing deterred wax products for explosive. The method has the advantages of low production equipment investment, simple production process, low operation cost, safety, energy saving without solvent pollution, and the like.

Description

technical field [0001] The invention belongs to the technical field of special wax production, in particular to a method for sweating and producing insensitive wax for explosives. Background technique [0002] Explosives are substances that can burn or decompose quickly. Under the action of certain external energy, they can burn violently (that is, explode) in a very short period of time to generate a large amount of heat and gas, and perform stable detonation work on the outside world. The widespread use of explosives has played an important role in promoting the material civilization of human society. [0003] The main explosive used during the Second World War was TNT, and the commonly used explosives are RDX (RDX, cyclotrimethylammonium trinitrate) and Octogen (HMX, cyclotetramethylenetetranitramine). With the development of science and technology, all kinds of explosives are developing towards high power and high safety. [0004] Under certain conditions, the various ...

Problems solved by technology

Experiments have shown that when ordinary sweating and deoiling processes produce high melting point paraffin products with a melting point of about 70°C, even if the method of prolonging the sweating time and increasing the sweating termination temperature is adopted, the oil content on the wax in the later stage of sweating has nothing to do with the yield, that is, on the wax The oil content does not decrease with the decrease of the yield, so the ordinary sweat deoiling process is not suitable for the production of insensitive wax products for explosives with a melting point of 70 ℃ ~ 80 ℃, especially the oil content index cannot meet the technical indicators of insensitive wax for explosives Require

[0013] Compared with solvent deoiling, the sweating deoiling process is an intermittent operation, and the product yield is lower and the production cycle is longer, but the sweating deoiling process has the advantages of less investment, simple production process, low operating cost, safe production process, energy saving and It has the advantages of no pollution to the environment, and some manufacturers are still using this method to produce soap wax products

[0014] Over the years, the method of sweating and deoiling has been developed in terms of production equipment and technology, such as CN89214332 (vertical square multi-segment partition sweating tank), CN94223980.6 (dish-type sweating device), CN98233254.8 (paraffin wax sweating tank), CN200920033500.X (new paraffin sweating tank), CN201210508905.0 (a high-efficiency paraffin sweating device), CN201320127680.4 (tubular paraffin deoiling device), etc., have made improvements in sweating and deoiling production equipment; CN91206202 (a High-efficiency paraffin wax sweating tank) has made improvements in the sweating and deoiling process, but these improvements still cannot produce insensitive wax products for explosives with a melting point of 70°C to 80°C
