Description
Tennmiddel for faststoff-drivladninger. Igniter for solid propellant charges.
For antenning av drivladninger er det kjent tennstoff-blandinger som inneholder tennstoffer som tricinat og tetrazen, kjent under navnet "Sinoxid", og hvortil det er tilblandet termiske bestanddeler som kalsiumsilicid og antimontrisulfid som forbrenner ved hjelp av oksydasjonsmidler som bariumnitrat, kaliumnitrat, metalloksyder osv. Disse tennsatser utvikler en stor varme og er variable i deres slagfølsomhet alt etter innholdet av tetrazen som man til-setter disse blandinger. For the ignition of propellant charges, there are known igniter mixtures which contain igniters such as tricinate and tetrazene, known under the name "Sinoxide", and to which are mixed thermal components such as calcium silicide and antimony trisulphide which burn with the help of oxidizing agents such as barium nitrate, potassium nitrate, metal oxides, etc. These igniters develop a great deal of heat and are variable in their impact sensitivity according to the content of tetrazene that is added to these mixtures.
Disse blandinger etterlater ved avbrenning faste bestanddeler som slår seg ned i løp og i patronhylse som blyforbindelser, metalloksyder og karbon. Ved bestemte anvendelsesformål kan disse residua, virke uheldige, nemlig i de tilfeller hvor man etter skuddet legger vekt på en ren overflate på forbrenningskammeret og i løpet. When burned, these mixtures leave behind solid components that settle in the barrel and in the cartridge case, such as lead compounds, metal oxides and carbon. For specific applications, these residues can appear unfortunate, namely in cases where, after the shot, emphasis is placed on a clean surface on the combustion chamber and in the barrel.
Forstyrrende rester danner seg også ved forbrenning av slagfølsomme blandinger av nitrocellulose og metalliske komponenter som aluminium, magnesium, kalsiumsilicid og blypikrat, ennskjønt nitrocellulosepulver alene som bekjent brenner uten nevneverdig rest. Disturbing residues are also formed when burning impact-sensitive mixtures of nitrocellulose and metallic components such as aluminium, magnesium, calcium silicide and lead picrate, although nitrocellulose powder alone as known burns without significant residue.
Oppfinnelsens formål er å tilveiebringe et slagfølsomt tennmiddel for faststoff-drivladninger, hvor de ovenfornevnte ulemper, spesielt dannelsen av forbrenningsrester, er unngått. Oppfinnelsen vedrører altså tennmiddel for faststoff-drivladninger som er karakterisert ved at det omfatter en blanding av et slagfølsomt diazo-, triazol- eller tetraz<p>lderivat, eksempelvis 5-amino-tetrazol eller diazodinitrofenol, fortrinnsvis tetrazen og nitrocellulose i forholdet 1:20 - 4:1, fortrinnsvis 1:20 - 1:1, beregnet etter vekt. The object of the invention is to provide an impact-sensitive ignition agent for solid propellant charges, where the above-mentioned disadvantages, especially the formation of combustion residues, are avoided. The invention thus relates to an ignition agent for solid propellant charges which is characterized in that it comprises a mixture of an impact-sensitive diazo, triazole or tetraz<p>l derivative, for example 5-amino-tetrazole or diazodinitrophenol, preferably tetrazene and nitrocellulose in a ratio of 1:20 - 4:1, preferably 1:20 - 1:1, calculated by weight.
Det har vist seg at - enskjønt på den ene side nitrocellulosekrutt har en forholdsvis mindre slagfølsomhet og på den annen side tetrazen viser en tilstrekkelig følsomhet bare ved hjelp . av friksjonsmidler, f.eks. ved tilblanding av hårde bestanddeler som kalsiumsilicid eller glass - en god blanding av nitrocellulose med tetrazen også uten tilblanding av hårde bestanddeler har en høy slag-følsomhet. It has been shown that - although on the one hand nitrocellulose gunpowder has relatively less impact sensitivity and on the other hand tetrazen shows a sufficient sensitivity only with the aid of . of friction agents, e.g. by mixing hard components such as calcium silicide or glass - a good mixture of nitrocellulose with tetrazen also without mixing hard components has a high impact sensitivity.
Ved et ytterligere forslag ifølge oppfinnelsen er det foreskrevet en tilsetning av inntil - referert til samlet blanding - 30 vektprosent av en eller flere nitroforbindelser, eksempelvis nitropenta, nitromannit o.l., hvorved blandingens tennevne lar seg forandre resp. forbedre. In a further proposal according to the invention, an addition of up to - referred to the total mixture - 30 percent by weight of one or more nitro compounds, for example nitropenta, nitromannite etc., is prescribed, whereby the mixture's ignition ability can be changed resp. improve.
I hensiktsmessig videre utforming av oppfinnelsen fore-slås det å korne blandingen på i og for seg kjent måte ved hjelp av oppløsningsmidler som aceton-, etyl- og metylacetat og/eller kolloid-stoffer som lim, gelatin, dekstrin, idet med sistnevnte kolloid-stoffer kan blandingen gis kuleform for oppnåelse av en bedre risle-evne etter tørkingen'. In an appropriate further design of the invention, it is proposed to granulate the mixture in a manner known per se by means of solvents such as acetone, ethyl and methyl acetate and/or colloidal substances such as glue, gelatin, dextrin, with the latter colloidal substances, the mixture can be ball-shaped to achieve a better trickling ability after drying'.
En kornet blanding bestående av 50 vektprosent tetrazen og 50 vektprosent nitrocellulose gir en slagfølsomhet målt ifølge fallhammermetoden etter BAM på 0,03 mkp (1 kg fallvekt). Ren nitrocellulose ligger i sin følsomhet ved ca. 0,35 mkp og tetrazen ved 0,2 mkp. Man kan nedsette tetrazeninnholdet inntil 5 vektprosent og har da ennå en følsomhet på ca. 0,2 mkp og ligger altså dermed ennå stadig under den rene nitrocelluloses følsomhet. A granular mixture consisting of 50% by weight tetrazene and 50% by weight nitrocellulose gives an impact sensitivity measured according to the drop hammer method according to BAM of 0.03 mkp (1 kg drop weight). Pure nitrocellulose lies in its sensitivity at approx. 0.35 mkp and tetrazene at 0.2 mkp. You can reduce the tetrazene content to 5% by weight and still have a sensitivity of approx. 0.2 mkp and is thus still below the sensitivity of pure nitrocellulose.
Sammenlignet hermed har en tennsatsblanding av oven-nevnte type, hvor komponentene er sammenblandet mekanisk med hverandre under samme betingelser en slagfølsomhet på 0,1-0,2 mkp. Compared to this, a primer mixture of the above-mentioned type, where the components are mechanically mixed with each other under the same conditions, has an impact sensitivity of 0.1-0.2 mkp.
I begge tilfeller er det altså blandingens slagfølsomhet lik eller bedre enn for de slagfølsommere komponenter. In both cases, the impact sensitivity of the mixture is therefore equal to or better than that of the more impact-sensitive components.
En mengde på 5 mg av en blanding av 50 vektprosent nitrocellulose og 50 vektprosent tetrazen er tilstrekkelig for f.eks. An amount of 5 mg of a mixture of 50% by weight of nitrocellulose and 50% by weight of tetrazene is sufficient for e.g.
å antenne l60 mg nitrocellulosekrutt og bringe det til fullstendig omsetning. Dette forhold lar seg riktignok dessuten forandre innen vide grenser ved anordningen og de geometriske forhold. to ignite l60 mg of nitrocellulose powder and bring it to complete conversion. This ratio can, of course, also be changed within wide limits by the device and the geometrical conditions.
Anvendelsesmulighetene av tennmidlet ifølge oppfinnelsen er svært mangesidige. Spesielt lar det seg anvende i utsparingen fra av drivmiddel som nitrocellulose eller nitroglyserol og nitrocellulose fremstilte ringformede hylseløse drivkarduser for bolte-pistoler. Selvsagt er det også tenkelig å påføre resp. anordne tennmidlet på overflaten av et hvilket som helst annet formet driv-kruttlegeme. The application possibilities of the ignition agent according to the invention are very versatile. In particular, it can be used in the recess from propellant such as nitrocellulose or nitroglycerol and nitrocellulose produced ring-shaped sleeveless propellant cartridges for bolt guns. Of course, it is also conceivable to apply resp. arranging the igniter on the surface of any other shaped propellant body.
