Abstract
Description
15 20 25 30 511 285 Smältgjutna laddningar av blandsprängämnen där TNT används som gjutmatris är välkända och har länge använts i militära tillämpningar. Exempel på sådana bland- sprängämnen är TNT/RDX (Cyclotol, Hexotol, Comp.B, HT); TNT/HMX (Octol); TNT/RDX/Al (Hexotonal, Torpex, Trialene, HTA, HBX-1, HBX-3, H-6); TNT/HMX/Al (Octonal, HTA-3); TNT/RDX/HMX; TNT/RDX/HMX/Al. 15 20 25 30 511 285 Molten castings of mixed explosives where TNT is used as a casting matrix are well known and have long been used in military applications. Examples of such mixed explosives are TNT / RDX (Cyclotol, Hexotol, Comp.B, HT); TNT / HMX (Octol); TNT / RDX / Al (Hexotonal, Torpex, Trialene, HTA, HBX-1, HBX-3, H-6); TNT / HMX / Al (Octonal, HTA-3); TNT / RDX / HMX; TNT / RDX / HMX / Al.
Enligt uppfinningen kan ADN (ammoniumdinitramid ) ersätta TNT som gjutmatris i sådana laddningar och ge ett blandsprängämne med högre prestanda. TNT har en. smältpunkt på ca. 80°C och ADN på 92°C. Skillnaden i smältpunkt är inte större än att väsentligen samma tillverkningsprocesser kan användas när laddningama framställs med den nya gjutmatrisen.According to the invention, ADN (ammonium dinitramide) can replace TNT as a casting matrix in such charges and provide a higher performance mixing explosive. TNT has one. melting point of approx. 80 ° C and DNA at 92 ° C. The difference in melting point is not greater than that essentially the same manufacturing processes can be used when the charges are produced with the new casting matrix.
Detonationsprestandan för ren ADN är något lägre än för TNT, men blandningar av ADN och HMX, RDX, HNIW m.fl. ger betydligt högre prestanda än blandningar av motsvarande sprängämne och TNT.Detonation performance for pure ADN is slightly lower than for TNT, but mixtures of ADN and HMX, RDX, HNIW and others. gives significantly higher performance than mixtures of the corresponding explosive and TNT.
Det nya förfarandet lämpar sig speciellt väl för framställning av RSV-laddningar, där smältgjuttekniken har stora fördelar samtidigt som det är önskvärt att uppnå en högre prestanda hos laddningama.The new method is particularly well suited for the production of RSV charges, where the molten casting technique has great advantages while it is desirable to achieve a higher performance of the charges.
Teoretiska beräkningar av detonationsprestanda i RSV-tillämpningar för olika blandningar har gjorts med programmet Cheetah varvid detonationspestandan för HMX använts som bas och satts till 100%. Resultatet framgår av nedanstående tabell: Sprärgämne Blandning vikt%/vikt% Prestanda, % av HMX TNT/RDX 30/70 80 TNT/HMX 30/70 85 ADN/RDX 30/70 95 ADN/HMX 30/70 101 ADN/HNIW 30/70 112 En blandning av ADN/HMX 30/70 har samma prestanda som ren HMX, dvs man kan utan prestandaförlust smältgjuta HMX genom att använda ADN som gjutmatris.Theoretical calculations of detonation performance in RSV applications for different mixtures have been made with the Cheetah program, using the detonation performance of HMX as a base and set to 100%. The results are shown in the table below: Explosive Mixture weight% / wt% Performance,% of HMX TNT / RDX 30/70 80 TNT / HMX 30/70 85 ADN / RDX 30/70 95 ADN / HMX 30/70 101 ADN / HNIW 30 / 70 112 A mixture of ADN / HMX 30/70 has the same performance as pure HMX, ie you can melt-cast HMX without loss of performance by using ADN as a casting matrix.
Prestandavärdena i tabellen avser blandningar, dvs för ADN/HNIW (ADN/CL-20) det fall att man suspenderar HNlWi smält ADN. Såsom beskrivs i svenska 10 15 20 25 30 35 a 511 285 patentansökningen 9701394-0 kan HNIW även lösas i smält ADN varvid ett komp- lex av ADN och HNIW emålles. Prestandan för komplexet är större än för bland- ningen.The performance values in the table refer to mixtures, ie for ADN / HNIW (ADN / CL-20) the case of suspending HN1Wi molten ADN. As described in Swedish patent application 9701394-0, HNIW can also be dissolved in molten ADN, whereby a complex of ADN and HNIW is milled. The performance of the complex is greater than that of the mixture.
I laddningama kan även inblandas aluminiumpulver och andra tillsatser på samma sätt som är känt från framställning av laddningar med TNT som gjutrnatris. När aluminiserade laddningar framställs kan sprängämnet först granuleras med alumini- umpulver, t.ex. såsom beskrivs i US 4,376,083, innan det blandas med gjutmatri- i sen.Aluminum powders and other additives can also be mixed into the charges in the same way as is known from the production of charges with TNT as cast iron. When aluminized charges are produced, the explosive can first be granulated with aluminum powder, e.g. as described in US 4,376,083, before mixing with the casting matrix.
Uppfinningen skall i det följande belysas med exempel.The invention will be illustrated by way of example below.
Exempel 1. 3 g ADN smältes i en liten termostaterad stålbägare , som invändigt var belagd med Teflon. Terrnostaten var inställd på 105°C. 6 g HMX (200 um) tillsattes och blanda- des med smältan. Ett litet ankare av rostfritt stål hângdes ner i blandningen. Provet kyldes genom att tennostaten ställdes ner till 94°C i ca 7 minuter och därefter stängdes av helt. När provet kallnat drogs det försiktigt ur bägaren med ankaret.Example 1. 3 g of DNA was melted in a small thermostated steel beaker, which was internally coated with Te fl on. The thermostat was set at 105 ° C. 6 g of HMX (200 μm) was added and mixed with the melt. A small stainless steel anchor was hung into the mixture. The sample was cooled by lowering the tin state to 94 ° C for about 7 minutes and then turning it off completely. When the sample had cooled, it was carefully pulled out of the beaker with the anchor.
Provet upprepades med tillsats av RDX och blandningar av HMX och RDX till smält ADN.The test was repeated with the addition of RDX and mixtures of HMX and RDX to fused DNA.
Proven undersöktes i DSC. Ingen komplexbildning eller exotenner p.g.a. kompabili- tetsproblem kunde konstateras. Ej heller kunde någon förändring noteras på vare sig ADN-matrisen eller de inblandade spràngämnena vid delning av de gjutna pro- vema.The samples were examined in DSC. No complex formation or exotic teeth due to compatibility issues could be identified. Nor could any change be noted on either the DNA matrix or the explosives involved in the division of the cast samples.
Exempel 2. 3 g ADN smältes på samma sätt som i exempel 1 och 6 g HNIW tillsattes och blan- dades med smältan. Blandningen utfördes relativt snabbt för att undvika att HNlWi någon större utsträckning löste sig i smältan. Provet kyldes genom att terrnostaten stängdes av.Example 2. 3 g of ADN was melted in the same manner as in Example 1 and 6 g of HNIW was added and mixed with the melt. The mixing was performed relatively quickly to avoid that HNlWi to any great extent dissolved in the melt. The sample was cooled by turning off the thermostat.
Provet undersöktes i DSC. Vid 92 °C smälte ADN-fasen medan HNIW kristallema föreföll opåverkade.The sample was examined in DSC. At 92 ° C, the ADN phase melted while the HNIW crystals appeared unaffected.
