Abstract
The invention relates to a powdery emulsion explosive with low detonation velocity. A rock powdery emulsion explosive, talcum powder and coarse bran are placed into a mixer for fullly stirring to ensure that the mixture is mixed evenly and then is packaged and sold, wherein the bulk density of the rock powdery emulsion explosive is between 0.58 and 0.62/g.cm<-3>, the detonation velocity is between 3,500 and 3,700/m.s<-1>, the brisance is between 15 and 17/mm, the sympathetic detonation is between 9 and 11/cm, the capacity for work is 360/ml, and the storage period is 6 months; the bulk density of the talcum powder is between 0.95 and 1.0/g.cm<-3>, and the grain diameter is 300 meshes; and the bulk density of the coarse bran is between 0.28 and 0.35/g.cm<-3>, and the grain diameter is between 0.8 and 1mmr. In the invention, the powdery emulsion explosive with low detonation velocity is applied to double metal explosive welding first, which ensures the quality of explosive welding of double metal explosive composite welding and ensures that the double metal explosive welding fully meets the requirement. The powdery emulsion explosive is safe, also has no pollution after the explosion, and has no harm to the health of blasters. The storage period of the powdery emulsion explosive with low detonation velocity can reach more than 180 days, so the powdery emulsion explosive can be mixed by manufacturers without field mixed-making and the labor intensity of the blasters is reduced.
Description
Technical field
The present invention relates to a kind of explosive of using in the bimetal explosive clad plate welding technique of being applied to, exactly is a kind of low detonation velocity powdery emulsifying explosive.
Background technology
It is that its explosion velocity of requirement is at 1900-2300ms that the bimetal explosive clad plate welds used explosive
-1Low explosive, be mostly that the scene prepares to such an extent that do not have the low explosive of storage period, also be not specifically designed to the explosive of explosive welding at present.Before No. 2 rock an-tnt explosives were not eliminated, add smoke suppressor and thinner in No. 2 rock an-tnt explosives was best explosive clad plate welding medication always.An-tnt explosive is eliminated now, and recent many people have done the status that a large amount of research replaces an-tnt explosive.People adopt more is added the purpose that thinner reaches low explosion velocity in high explosive; Also the someone to adopt No. 2 anti-water rock dynamites that do not contain high explosive be main body, be equipped with corresponding flame-cooling agent and density adjuster, though satisfied the requirement of bimetal blast composite welding, but and explosive welding medication at present still has following problem: contain high explosive in (1) explosive welding medication component, the poor stability in the use.(2) the easy moisture absorption of additive makes explosive not have the shelf lives in the explosive component, needs the on-the-spot system of mixing, and has strengthened dynamiter's labour intensity.(3) the explosive welding medication adopts hand mixing to mix system, causes easily to mix inhomogeneously to cause the detonation property instability, thereby causes Double Metal Explosive Welding compound defective.Therefore, the quick-fried weldering medication that development does not a kind ofly contain high explosive, certain shelf lives is arranged, detonation property is stable is people's urgent problems.
Summary of the invention
The objective of the invention is at existing defective, to the explosive of using in the bimetal explosive clad plate welding technique that people provide a kind of and do not contain high explosive, certain shelf lives is arranged, detonation property is stable, exactly is a kind of low detonation velocity powdery emulsifying explosive.
Technical solution of the present invention:
The present invention makes (consumption is a weight part) by following component
Powdery emulsifying explosive 60～70 talcum powder 5～20 chaffs 20～25.
The powdery emulsifying explosive that adopts is the rock type powdery emulsifying explosive, and its tap density is 0.58～0.62/gcm
-3, explosion velocity is 3500～3700/ms
-1, brisance is 15～17/mm, and induced detonation is 9～11/cm, and capacity for work is 360/ml, and the shelf lives is 6 months; The talcum powder that adopts is that tap density is 0.95～1.0/gcm
-3, particle diameter is 300 orders; The chaff that adopts is that tap density is 0.28～0.35/gcm
-3, particle diameter is 0.8～1mm.
Above-mentioned each component is made production method of the present invention is:
(1) gets rock type powdery emulsifying explosive, talcum powder and the chaff that is adopted in described ratio;
(2) above-mentioned raw materials is put into mixing tank and fully stirred, it is mixed;
(3) packing, sale.
The powdery emulsifying explosive that the present invention adopts is the rock type powdery emulsifying explosive, and it is a kind of high-performance infant industry explosive that does not contain single chmical compound explosive, and this explosive is the infant industry explosive of a kind of excellent property of growing up on colloid emulsion explosive basis.Adopt emulsifying technology that oxygenant and high performance fuel are mixed the latex of making high homogeneity, use advanced spray pulverization technology to make powdery emulsifying explosive then.This explosive, from microcosmic, each particle is actually the solid-state emulsifying base of a fritter, has still kept the characteristics that the emulsion explosive mixing uniformity is good and have a water resisting property.Its water resisting property and anti-caking effect obviously are better than No. 2 an-tnt explosives, bulking ammonium nitrate explosive, powdered ammonium nitrate-fuel oil explosive.The talcum powder that the present invention adopts is the powdery inert substance at normal temperatures, and ginseng is mixed in the powdery emulsifying explosive, and the detonation property that it can directly reduce powdery emulsifying explosive can play the effect of deterrent.The chaff appearance that the present invention adopts is similar to wood powder, bigger specific surface area and total surface area are arranged, have sensibilized and fluffing action, participate in the shelf lives that to improve the blast system in the powdery emulsifying explosive, contain macromolecular organic compound in the chaff simultaneously, therefore in explosive reaction, have the effect of combustible agent, can impel the blast system to stablize propagation of explosion.
Effect of the present invention
1, the present invention is because the powdery emulsifying explosive that adopts is the rock type powdery emulsifying explosive, adopt talcum powder and chaff again, the powdery emulsifying explosive explosion velocity is reduced, thereby take the lead in low detonation velocity powdery emulsifying explosive is applied in the Double Metal Explosive Welding, guaranteed the quality of its explosive welding of bimetal blast composite welding, it is met the requirements fully.
2, the present invention has adopted machinery to puddle owing to do not contain other high explosives such as TNT in the prescription simultaneously, and therefore not only safety but also quick-fried back are pollution-free, to the healthy nothing harm of big gun worker.
3, among the present invention because what add is talcum powder and chaff, therefore moisture low, nonhygroscopic, free-running property is good, thereby strengthened the stability of explosive component, guaranteed the shelf lives of rock type powdery emulsifying explosive, the shelf lives of this low-order detonation welding powdery emulsifying explosive can be reached more than 180 days, make thereby can mix, need not the on-the-spot system of mixing, reduced big gun worker's labour intensity by manufacturer.
