Embodiment 1

[0007] Example 1: Proportion by weight: 70% ammonium nitrate, 12% wood flour, 17.5% sodium chloride, and 0.5% modifier. Prepare raw materials, mix ammonium nitrate and modifier to expand ammonium nitrate, Then add wood flour and sodium chloride, crush and mix.

Embodiment 2

[0008] Example 2: Proportion by weight: ammonium nitrate is 73%, wood flour is 11%, sodium chloride is 15%, and modifier is 1%. Prepare raw materials, mix ammonium nitrate and modifier to expand ammonium nitrate, Then add wood flour and sodium chloride, crush and mix.

[0009] The modifier in Example 1 and Example 2 is the modifier disclosed in the invention patent with the authorized announcement number CN 1266041C.

[0010] The requirements of the present invention are:

[0011] ① This explosive has good detonation sensitivity and can be detonated with a No. 8 detonator. The depth of the detonator inserted into the explosive is not less than two-thirds of the length of the detonator;

[0012] ② It is not advisable to add other materials during use;

[0013] ③ It is strictly prohibited to use this explosive in the open air during the rainy season;

[0014] ④. The unused explosives should be put into a plastic bag, tied up, and stored in a dry warehouse to prevent moisture absorpt...

Abstract

The invention provides ammonia dynamite for the explosive compound welding of a titanium plate and a steel plate, which is stable in explosion velocity and good in welding effect. The invention adopts a technical proposal that the ammonia dynamite for the explosive compound welding of the titanium plate and the steel plate comprises the following components by weight percentage: 68 to 74 percent of ammonium nitrate, 8 to 13 percent of wood meal, 14 to 18 percent of sodium chloride and 0.5 to 1.0 percent of modifier, wherein the modifier comprises the following components by weight percentage: 40 to 50 percent of octadecylamine, 15 to 25 percent of wax, 25 to 35 percent of microcrystalline wax and 3.5 to 6.5 percent of sodium lauryl sulfate. The method for preparing the ammonia dynamite for the explosive compound welding of the titanium plate and the steel plate comprises the following steps: mixing the ammonium nitrate and the modifier to puff the ammonium nitrate; adding the wood meal and the sodium chloride; and grinding and mixing the materials to obtain the ammonia dynamite for the explosive compound welding of the titanium plate and the steel plate.

Description

Technical field [0001] The invention relates to an ammonium nitrate explosive for explosive composite welding of a titanium plate and a steel plate. Background technique [0002] The current explosives used for the explosive composite of titanium plate and steel plate have shortcomings. The specific manifestations are: ①The explosive velocity is unstable, which affects the quality of the explosive composite welding of titanium steel; ②The explosive production process is complicated; ③Contains toxic and harmful components such as TNT ④The cost of explosives is high. Summary of the invention [0003] The purpose of the present invention is to provide an ammonium nitrate explosive for explosive composite welding of titanium plate and steel plate with stable detonation speed and good welding effect. [0004] To this end, the technical solution of the present invention is: ammonium nitrate explosive for explosive composite welding of titanium plate and steel plate, its components and...
