Abstract
The present invention relates to a method for preparing a low-trinitrotoluene ammonium nitrate trinitrotoluene oil explosive for engineering blasting. The low-trinitrotoluene ammonium nitrate trinitrotoluene oil explosive is composed of powdery ammonium nitrate, wood powder, trinitrotoluene, a compound oil phase and additives. An airflow-rolling method is used for producing an ammonium nitrate trinitrotoluene oil explosive. The existing production equipment for producing the ammonium nitrate trinitrotoluene oil explosive only needs to be changed by the preparation method slightly, partial prescription is adjusted, and then a product which is better than an N0.4 ammonium nitrate trinitrotoluene oil explosive can be produced. The present invention is suitable for extensive manufacturers using an airflow-rolling technology for producing a powdery ammonium nitrate trinitrotoluene oil explosive to use, and has major popularizing value.
Description
The present invention relates to a kind of powdery pyrotechnic composition, especially a kind of preparation method who contains No. 4 rock powdery an-tnt-oil explosives of low ladder.
Nineteen ninety-five, my company cooperated with the Changsha Mining ﹠ Metallurgy Inst, introduction contains the production technology of No. 2%4 rock an-tnt-oil explosives of ladder, adopt air-flow---rolling two-stage method production technique, carried out the secondary industrial experimentation at my company scene, product explosion velocity detected result is 2976m/s and 3049m/s, induced detonation is not succeedd less than 4cm.In March, 1996, held national rock powdery an-tnt-oil explosive mass analysis exchanging meeting in Zengcheng City, Guangdong Province, Changsha Mining ﹠ Metallurgy Inst has at the meeting done the speech of " rock powdery an-tnt-oil explosive production technology working report ", it has negated the possibility that No. 4 rock an-tnt-oil explosives are produced in application " air-flow---rolling technology ", think and to remove air stream drying ammonium nitrate technology, use the rolling method that the fifties generally uses instead, just might produce an-tnt-oil explosive No. 4.Really, domestic have several producers to remove expensive nearly 1,000,000 yuan pneumatic conveying dryer, uses wheel roller instead and produce No. 4 rock an-tnt-oil explosives.Yet, air stream drying ammonium nitrate technology is the comparatively advanced production technique that China's the seventies just grows up, there is most of utilization air-flow---the rolling production technique of tame industrial explosive material factory more than 500 in the whole nation, remove air stream drying ammonium nitrate capital improvement wheel roller production unit, the whole nation will be a quite surprising fund input.
Purpose of the present invention just provides a small amount of production unit of changing existing an-tnt-oil explosive of a kind of need, and the adjustment member prescription just can be produced the product that is better than No. 4 an-tnt-oil explosives.
Low TNT-equivalent ammonium nitrate-fuel oil explosive of the present invention is made up of powdery ammonium nitrate, wood powder, tritonal, compound oil phase, additive, compound oil phase is the mixture of compound special-purpose grease and department's benzene-80, its weight percent is: compound special-purpose grease 90～95%, department's benzene-80 5～10%.Additive is sodium lauryl sulphate, alkyl acid phosphate monoester, potassium primary phosphate, octadecane sebacoyl amine, Sorbitol Powder tetranitrate, talcum magnesite and whiting, select the mixture of its 2～3 kinds of combinations, its weight percent in explosive is 0.1～0.2%.Selecting for use price lower compound special-purpose grease to replace waxes such as the higher paraffin of price in Changsha Mining ﹠ Metallurgy Inst's prescription, vaseline is oil phase material.Replaced expensive properties-correcting agent with additive, through measuring and calculating, from saving energy and reduce the cost of expense of saving material and novel process, than the Technology of Changsha Mining ﹠ Metallurgy Inst, explosive per ton can reduce production costs more than 80 yuan.
The preparation method of low TNT-equivalent ammonium nitrate-fuel oil explosive of the present invention: (1) is got 89.5～92.5% ammonium nitrate by weight percentage and is dropped into crusher in crushing, rate of feeding≤1500kg/h, pulverize through pulverizer again, pass through 40 mesh sieves more than 90%, carry separator, separate discharging, 65 ℃～75 ℃ of drop temperatures, water content≤0.12%; After (2) 0.1～0.2% additives and ammonium nitrate slightly mix, drop into wheel roller and grind mixed, when playing big dirt, add 2.2～2.8% compound oil phases, grind and mix, every each rolling material of wheel roller is≤250kg always to grind and did time 15～25 minutes; Wood powder by 40 mesh sieves more than (3) 90% drops into drying plant drying, dried wood powder water content≤2%; (4) the ammonium oil compound with (2) drops into wheel roller, cool, wait to expect below the temperature drop to 70 ℃, drop into 1.8～2.2% tritonal, by 60 mesh sieves, grind mixed and be no less than 7 minutes more than 95%, add 4～5% wood powders, grind again to mix and be no less than discharging in 5 minutes, 45 ℃～55 ℃ of drop temperatures, water content≤0.15%.
The present invention and existing rolling two-stage method are produced low TNT-equivalent ammonium nitrate-fuel oil explosive following characteristics: (1) rolling technology is pressed 40～50 minutes/platform of nitre contaminated product, and the present invention only needs 20 minutes/platform, has improved production efficiency greatly; (2) select price lower compound special-purpose grease and additive for use, and novel process is energy-saving and cost-reducing, produces explosive cost per ton and reduce more than 80 yuan; (3) because tritonal content is few, reduced the harm of toxic gas, added a spot of oil phase, greatly reduced dust concentration, improved workman's operating environment, reduced pollution surrounding environment to human body; (4) explosive of the present invention is difficult for the moisture absorption hardening, after long-time the storage, still guarantees blast performance; (5) need not remove air stream drying ammonium nitrate technology, just can produce low TNT-equivalent ammonium nitrate-fuel oil explosive, can produce in enormous quantities, be fit to vast air-flow---rolling explained hereafter powdery an-tnt-oil explosive producer uses, and has bigger promotional value.
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is a process flow sheet of the present invention.
