Abstract
The invention relates to an emulsion powder explosive that has low detonation velocity. The feature is that it has 80-95 portions emulsion powder explosive, 5-20 portions diluents agent, and 0-10 portions density regulator. It could gain emulsion powder explosive that has 2000-2800m/s low detonation velocity, and density at 0.5-1.0g/cm3. The invention could lower the cost to 10-15% and has no adverse effect to explosive.
Description
Technical field
The present invention is the improvement to the engineering explosion emulsified powder-like explosive, relates in particular to a kind of emulsified powder-like explosive with low explosion velocity.
Background technology
Existing emulsified powder-like explosive, for example the disclosed emulsified powder-like explosive of Chinese patent CN91107080.X, CN93117971.8 is made up of oxygenant, oil phase reductive agent.This type of explosion velocity of explosive is higher, and generally all between 3800-4200m/s, this detonating explosive is for some little burdens and soft rock explosion, and blasting effect is not ideal enough, and the explosive cost is higher.The improved place of being worth is arranged.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned prior art, provide a kind of explosion velocity low, and have the emulsified powder-like explosive of lower cost.
The object of the invention realizes that main the improvement is to add thinner and/or density adjuster in the emulsified powder-like explosive that makes, and reduces explosion velocity of explosive and density.Specifically, emulsified powder-like explosive of the present invention is characterized in that by 80-95 part emulsified powder-like explosive, 5-20 part thinner, and 0-10 part density adjuster is formed.
The present invention adds thinner in emulsified powder-like explosive, can effectively reduce explosion velocity of explosive, and can reduce the explosive cost, used thinner is relative emulsified powder-like explosive inert additive, as powdery carbonate, talcum powder, stone flour etc., wherein better select lime carbonate, talcum powder for use, can significantly reduce the explosive cost, and raw material sources are easy to get.Add density adjuster, can regulate medicinal powder density, also have the effect of the explosion velocity of reduction simultaneously, should select relative emulsified powder-like explosive inertia for use and have low density, nonhygroscopic granular or powder material, as polystyrene, hydrophobic nature perlite, urethane etc.The present invention better adopts the hydrophobic nature perlite, and not only density is little, and cost is low, do not need to process separately, and easily mixcibility is good.
Emulsified powder-like explosive of the present invention can be various known emulsified powder-like explosives, has no special requirements.
The present invention not only can effectively reduce explosion velocity of explosive owing to add thinner and/or density adjuster in emulsified powder-like explosive, can obtain the low explosion velocity of 2000-2800m/s, and density is 0.5-1.0g/cm
3Emulsified powder-like explosive makes it to be applicable to that some is to the low occasion use of explosion velocity requirement; And can obviously reduce the explosive cost, can reduce explosive cost 10-15%, and explosive is had no adverse effects.For emulsified powder-like explosive has increased by class new variety.
Below in conjunction with several embodiments, further specify the present invention
