Example Embodiment
[0027] Example one:
[0028] Prepare the raw materials according to the following weight percentages, namely: 66.5 parts of ammonium nitrate, 6.5 parts of sodium nitrate, 12 parts of sodium chloride, 9 parts of water, 2.5 parts of composite emulsifier, 3.0 parts of composite wax, and 0.5 parts of additives. The composite wax is paraffin and The mixture of petroleum jelly, the weight ratio is 1:1, the additive is fatty alcohol, the production process operation steps:
[0029] (1) Heat the mixture of ammonium nitrate, sodium chloride, sodium nitrate, and water to 110°C~130°C to melt to form an oxidant solution, and filter;
[0030] (2) Heat the mixture of composite emulsifier, composite wax, and additives to 90℃~100℃ to melt, form a combustible solution, and filter;
[0031] (3) Use a metering pump to pump the oxidant water phase solution and the combustible oil phase solution into the static mixer for mixing, and then transport it into the first-stage emulsifier for emulsification, and...
