Embodiment 1

[0008] Take 82kg of ammonium nitrate, after being coarsely crushed by a crusher, it is sent to a jet mill for fine crushing and drying. The water content of the crushed and dried ammonium nitrate fine powder is ≤0.2%, and the fineness is ≥80%. The moisture content of 4kg wood flour after drying is ≤3.0%. Finally, ammonium nitrate fine powder and wood powder are added to a low-temperature medium weight mixer, and 0.2 kg of anionic surfactant and 0.7 kg of paraffin are added at the same time for grinding and mixing, and the material is discharged after grinding and mixing evenly. That is, the finished product is produced.

Embodiment 2

[0010] Take 87kg of ammonium nitrate, after being coarsely crushed by a crusher, it is sent to a jet mill for fine crushing and drying. The water content of the crushed and dried ammonium nitrate fine powder is ≤0.2%, and the fineness is ≥80%. The water content of 8kg bagasse powder after drying is ≤3.0%. Finally, the ammonium nitrate fine powder and bagasse powder are added to a low-temperature medium weight mixer, and 0.7 kg of cationic surfactant and 2 kg of heavy oil are added at the same time for grinding and mixing, and the material is discharged after grinding and mixing evenly. That is, the finished product is produced.

Embodiment 3

[0012] Take 92kg of ammonium nitrate, after coarse crushing by a crusher, send it to a jet mill for fine crushing and drying, the water content of the crushed and dried ammonium nitrate fine powder is ≤0.2%, and the fineness is ≥80%. The moisture content of 11kg of cottonseed cake powder after drying is ≤3.0%. Finally, the ammonium nitrate fine powder and cottonseed cake powder were added to the low-temperature medium weight mixer, and 1 kg of cationic surfactant and 3.2 kg of diesel oil were added at the same time for grinding and mixing, and the material was discharged after grinding and mixing evenly. That is, the finished product is produced.

Abstract

A composite explosion welding powder with eucalyptus oil for low explosion speed steel plate is prepared by taking ammonium nitrate 80-94 proportion, surface activator 0.1-1 proportion, loose inflammable agent 2-12 proportion and fuel oil 0.5-3.5 proportion and mixing proportionally. Its advantages include low cost, no environmental pollution and need for diluting agent and easy control for components, water content and fineness.

Description

technical field [0001] The invention relates to an ammonium oil explosive for composite explosion welding of low-detonation-velocity steel plates. Background technique [0002] Explosive welding technology is a trinity metal welding process that uses explosives as the energy source of pressure welding, fusion welding and diffusion welding: using explosives as the energy source, through the pulse load generated by the explosive detonation, a material (multi-layer) is pushed to a high-speed oblique collision Another material (base layer) realizes the metallurgical combination of two metals by the instantaneous high temperature and high pressure. The main purpose of the metal composite panels it produces is to replace expensive stainless steel and non-ferrous metals for petrochemical, chemical, ship, vehicle and heat-resistant, wear-resistant and special equipment or components to achieve the purpose of reducing engineering costs. Due to the special requirements of welding tec...
