Description
Technical field
The present invention relates to the special-purpose sensitizing agent of emulsion explosive, particularly a kind of fast foaming agent of emulsion explosive foaming.
Background technology
The effect of whipping agent: be in the emulsion explosive colloid, to form micro-bubble, utilize micro-bubble to produce focus, improve the density of explosive.Normally used chemical foaming agent is NaN0
3It is low to have cost, belong to characteristics such as automated job, if foaming condition control is proper, can obtain blasting performance preferably, but because of blowing temperature, factors such as foamed time are wayward, cause foaming effect undesirable, and then influence emulsion explosive and blasting performance, mainly have the deficiency of following several respects:
(1) Na
2N0
3Add as after the colloid, expansion rate is slow, need insulation for some time, just can reach requirement and sensitization effect, so just cause process interruption, be difficult to realize that the powder charge of emulsion explosive seals the serialization production of packing, influence production efficiency, and be incubated operation accordingly and equipment has increased energy consumption and production management cost;
(2) there is certain " aftereffect " effect, is meant the emulsion explosive product in depositing process, the medicine volumetric expansion, the powder stick spalling, water outlet is thinning, the phenomenon that blast performance descends;
(3) commonly used in the general foamed promoter have two classes, one class is acidic substance, as nitric acid, hydrochloric acid, phosphoric acid, stearic acid etc., another kind of is salts substances as nitric acid benzene, thiocarbamide, ammonium thiocyanate etc., generally speaking, the mineral acid promoter action is big, and acid strong foaming is fast, but corrodibility is strong, influences the work-ing life of machinery equipment simultaneously.The organic acid effect is less, but foaming is slow.
Summary of the invention
The purpose of this invention is to provide the stable fast foaming agent of a kind of safe mass, shortcoming such as it has overcome general whipping agent blow weak, and aftereffect is big.Fast foaming agent of the present invention has that expansion rate is fast, corrodibility is little, characteristics such as aftereffect is little, simultaneously, the ratio that it can adjust foam material according to the Recipe condition and the performance requriements of emulsion explosive, and mixing time is controlled foamed time, realize the serialization production of emulsion explosive packing, enhance productivity, reduce production costs.
Technical scheme of the present invention is to realize like this, a kind of fast foaming agent, it is characterized in that: it is made up of stablizer and promotor, the stablizer add-on is 0.3～0.5%(weight percentage of emulsion explosive), the promotor add-on is 1.2～1.5 times of stablizer of emulsion explosive, and described stablizer is made up of by following weight percentage following component: thiocarbamide is 0.5%～1.5%, Sodium Nitrite is 20%～30%, potassium nitrite is 3%～5%, water is 63.5%～76.5%; Described promotor is made up of by following weight percentage following component: ammonium nitrate is 7%～11%, nitric acid is 2%～3%, glacial acetic acid is 1%～3%, Sodium Thiocyanate 99 is 0.2%～0.5%, phosphoric acid is 0.5%～0.7%, Secondary ammonium phosphate is 1%～2%, citric acid is 0.5%～1.2%, urea is 1%～3%, water is 75.6%～86.8%.
Described a kind of fast foaming agent best composition is: described stablizer add-on is 0.4% of an emulsion explosive weight percentage, the promotor add-on is 1.3 times of stablizer of emulsion explosive, and described stablizer is made up of by following weight percentage following component: thiocarbamide is 1.5%, Sodium Nitrite is 25%, potassium nitrite is 4%, water is 69.5%; Described promotor is made up of by following weight percentage following component: ammonium nitrate is 8%, nitric acid is 2.5%, glacial acetic acid is 2%, Sodium Thiocyanate 99 is 0.3%, phosphoric acid is 0.6%, Secondary ammonium phosphate is 1.5%, citric acid is 0.8%, urea is 2%, water is 82.3%.
Reaction equation:
(1) mechanism of chemical foaming sensitization mainly is that stablizer and promotor chemical reaction are taken place and produced gas, and simultaneously, chemical foaming agent is by the weak acid environment of water and suitable temperature, decomposition reaction takes place and produces bubble.
(2) reaction equation: NH4N0

The invention has the beneficial effects as follows:
1, at first its compound fast foaming agent of forming by inorganics and organism, its blowing temperature moderate (40 ℃～50 ℃), chemical foaming gas is even, is of moderate size, and is evenly distributed, stable storing, generally speaking, the inorganic foaming agent promoter action is big, and is acid strong, foaming is fast, but to the poor storage stability of emulsion explosive.The organic blowing agent effect is less, but foaming is slow, and aftereffect is big, and is strict to variation of temperature simultaneously;
2, fast foaming agent production technology process of the present invention is simple, and foamed time short (the sensitizing time is short) aftereffect is suitable, and density is easy to control, and the nature shelf lives is long, can reach 1 year, use the explosive after this whipping agent sensitization simultaneously, not be afraid of extruding, characteristics such as have the explosion velocity height, brisance is big, and cost is low;
3, security is good, and this kind whipping agent flash-point height, raw material are simple, and general whipping agent (organic) and the security of (inorganic) whipping agent are better, little to machinery equipment corrodibility simultaneously;
4, its ratio that can adjust foam material according to the Recipe condition and the performance requriements of emulsion explosive, and mixing time is controlled foamed time, realizes the serialization production of emulsion explosive packing, enhances productivity, and reduces production costs.
