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
The present invention relates to a kind of titanium plate and steel plate ammonia dynamite for explosive compound welding.
Background technology
Being used for the blast of titanium plate and steel plate at present compoundly has weak point with explosive, is embodied in: the 1. explosion velocity instability of explosive influence the explode quality of composite welding of titanium steel; 2. explosive production process complexity; 3. contain poisonous and harmful components such as TNT; 4. explosive cost height.
Summary of the invention
The purpose of this invention is to provide a kind of explosion velocity is stable, welding effect is good titanium plate and steel plate ammonia dynamite for explosive compound welding.
For this reason, technical scheme of the present invention is: titanium plate and steel plate ammonia dynamite for explosive compound welding, and its component and weight proportion are: ammonium nitrate is 68～74%, and wood powder is 8～13%, and sodium-chlor is 14～18%, and properties-correcting agent is 0.5～1.0%; Wherein, the component of properties-correcting agent and weight proportion are: stearylamine is 40%～50%, and paraffin is 15%～25%, and Microcrystalline Wax is 25%～35%, and sodium lauryl sulphate is 3.5%～6.5%.
The preparation of titanium plate and steel plate ammonia dynamite for explosive compound welding: ammonium nitrate mixed making ammonium nitrate expanded with properties-correcting agent, add wood powder and sodium-chlor then, pulverize, mix.
Beneficial effect: the present invention is to be main component with the ammonium nitrate, adds appropriate modifier, wood powder and the modulation of sodium-chlor thinner and forms.The explosive material therefor does not all contain poisonous objectionable constituent, and processing is simple, does not need to add the ammoniumnitrate explosives that any equipment just can utilize original ammoniumnitrate explosives production line production the present invention to be developed.This explosive is to personnel and environmentally friendly, and the explosion velocity of explosive is stable, and material cost and production cost are all lower, are used in the blast composite welding of metallic substance such as titanium plate and steel plate, and be effective.The product salient features is as follows: induced detonation 〉=3cm, brisance are 9.0mm～11.0mm (density 0.85g/cm
3), explosion velocity is 2.5 * 10
3M/s-2.7 * 10
3M/s, natural tap density is 050g/cm
3-0.60g/cm
3, piling up explosion velocity naturally is 2.0 * 10
3M/s-2.2 * 10
3M/s, quick-fried power is 130-180ml.
Embodiment
Embodiment 1: by weight ratio: ammonium nitrate is 70%, and wood powder is 12%, and sodium-chlor is 17.5%, and properties-correcting agent is 0.5% preparation raw material, ammonium nitrate is mixed making ammonium nitrate expanded with properties-correcting agent, adds wood powder and sodium-chlor then, pulverizes, mixes.
Embodiment 2: by weight ratio: ammonium nitrate is 73%, and wood powder is 11%, and sodium-chlor is 15%, and properties-correcting agent is 1% preparation raw material, ammonium nitrate is mixed making ammonium nitrate expanded with properties-correcting agent, adds wood powder and sodium-chlor then, pulverizes, mixes.
Properties-correcting agent among described embodiment 1, the embodiment 2 is: Granted publication number is the disclosed properties-correcting agent of patent of invention of CN 1266041C.
Service requirements of the present invention is:
1., this explosive has detonation sensitivity preferably, can use No. 8 blasting cap initiations.Detonator inserts the explosive degree of depth and is not less than 2/3rds of cap length;
The material that should not add other when 2., using again;
3., forbid to use this explosive in the open in rainy season;
4., the explosive that the do not use tying in the plastics bag of should packing into, be placed on keeping in the exsiccant storehouse, in case the moisture absorption.
5., this explosive is only limited to titanium plate and steel plate blast composite welding usefulness.
