Den foreliggende opfindelse angår pyrotekniske røgsatser, der fremkalder røg, der er uigennemtrængelig i det synlige og infrarøde spektrum.The present invention relates to pyrotechnic smoke rates which produce smoke that is impervious to the visible and infrared spectrum.
Kunstig røg anvendes inden for teknikken for det første til at holde 5 frost borte fra beplantninger (især frugt- eller vinbeplantninger).Artificial smoke is used in the art firstly to keep 5 frosts away from plantings (especially fruit or vine plantings).
Dertil fremstilles normalt enten røg- eller olietåge, eller der udsprøjtes en fin vandtåge, der endvidere kan være stabiliseret med glycerin, fedtalkoholer eller lignende, og udbredes over den kultur, der skal beskyttes, i et mere eller mindre tykt lag for at reflektere 10 den fra jorden udstrålede varme og dermed forhindre afkøling. Disse tåger eller skyer må følgelig opretholdes over længere tid, dvs. det gennem udkondensering og vindbevægelse opståede tab må løbende fornys. Til dette formål anvendes derfor fortrinsvis kontinuerligt arbej dende anlæg.In addition, either smoke or oil mist is usually prepared, or a fine mist of water, which may also be stabilized with glycerin, fatty alcohols or the like, is sprayed and spread over the culture to be protected in a more or less thick layer to reflect it. radiated heat from the earth, thus preventing cooling. Accordingly, these fogs or clouds must be maintained for a longer period, ie. the losses incurred through condensation and wind movement must be continuously renewed. For this purpose, therefore, continuous working systems are preferably used.
15 Kunstige tåger finder endvidere anvendelse fremfor alt inden for den militære sektor til sløring af militære anlæg, troppeformationer og køretøjer. Især ved beskyttelse af troppeformationer og køretøjer gælder det om i kortere tid at unddrage modstanderen direkte observation deraf, hvortil der sædvanligvis i retning af modstanderen 20 afskydes en pyroteknisk ladning, der fordeler sig i lighed med et haglskud og danner mange røgfremkaldende partikler, der sørger for en særdeles hurtig og regelmæssig tilsløring af større arealer (jfr.15 Artificial fogs are also used above all in the military sector for blurring of military installations, troop formation and vehicles. Especially when protecting troop formation and vehicles, it is important to avoid direct observation of the opponent for a shorter period of time, to which a pyrotechnic charge, usually distributed like a shotgun, is usually dispensed and forms many smoke-producing particles which provide a very fast and regular blurring of larger areas (cf.
DE-AS 30 31 369 og den deri citerede litteratur).DE-AS 30 31 369 and the literature cited therein).
Til dette formål kendes et stort antal forskellige røg- og tågeblan-25 dinger. Eksempelvis kan nævnes titantetrachlorid, siliciumtetra- chlorid, chlorsulfonsyre eller kombinationer deraf med ammoniak eller svovltrioxid som flydende røgdannere eller rødt phosphor, HC-blandin-ger (hexachlorethan/zink/zinkoxid) og ammoniumperchlorat/zinkoxid som faste røgdannere. Ved anvendelse omdannes disse stoffer enten 30 gennem en sekundær forbrændingsreaktion eller gennem de ved deres omsætning med hinanden frigjorte egnede produkter. Afgørende for røgdannelsens kvalitet er dannelseshastigheden, udbredelseskoncentrationen og -formen såvel som varigheden af røgsløret. Der kendes allerede røgblandinger, der er egnede til alle disse formål (jfr.To this end, a large number of different smoke and fog mixtures are known. For example, titanium tetrachloride, silicon tetrachloride, chlorosulfonic acid or combinations thereof with ammonia or sulfur trioxide such as liquid fumigants or red phosphorus, HC mixtures (hexachloroethane / zinc / zinc oxide) and ammonium perchlorate / zinc oxide as solid fumigants may be mentioned. In use, these substances are converted either through a secondary combustion reaction or through the suitable products released by their reaction. Crucial to the quality of the smoke formation is the rate of formation, the concentration and shape of the distribution, as well as the duration of the smoke veil. Smoke mixtures suitable for all these purposes are already known (cf.

Med hensyn til en bred anvendelse inden for den moderne forsvars-5 teknik har disse blandinger dog en ganske væsentlig ulempe. Medens det tidligere især kom an på at opnå en i synligt lys så tæt røg som muligt, råder militære observatører i dag yderligere over infrarødt pejleudstyr og varmebilledeudstyr, der udnytter det faktum, at militære mål, på grund af deres energiomsætning, udsender meget intensiv 10 varmestråling, som kan detekteres på stor afstand. Da visse bølgelængder absorberes selektivt af atmosfæriske bestanddele såsom CO2 og vanddamp, arbejder sådant udstyr fortrinsvis i atmosfærens såkaldte "vinduer", der befinder sig ved 0,7-1,5 /xm, 2-2,5 /xm, 3-5 /xm og 8-12 /xm. Især bestræber man sig på at arbejde i området 8-12 /xm, 15 eftersom forstyrrelser på grund af røg, dis og normale tåger i dette område antager et minimum. I modsætning hertil er det derfor pyrotekniske røgsatsers opgave at tilvejebringe en absorption eller reflektion af IR-strålingen i dette område, der er så høj som mulig.However, for a wide application in the modern defense technique, these blends have a considerable disadvantage. While the former mainly came to achieve a visible smoke as dense as possible, military observers today still have infrared detectors and thermal imaging equipment that exploit the fact that military targets, due to their energy conversion, emit very intense 10 heat radiation that can be detected at a great distance. Since certain wavelengths are selectively absorbed by atmospheric constituents such as CO2 and water vapor, such equipment preferably operates in the so-called "windows" of the atmosphere which are at 0.7-1.5 µm, 2-2.5 µm, 3-5 xm and 8-12 / xm. In particular, efforts are made to work in the area of 8-12 µm, 15 as disturbances due to smoke, haze and normal fog in this area assume a minimum. In contrast, it is the task of pyrotechnic smoke rates to provide an absorption or reflection of the IR radiation in this range that is as high as possible.
Fra EP-A 37.515 er det endvidere kendt at kombinere røg fra halogen-20 donorer/metalpulvere eller phosphorrøg med en yderligere sekundær røg af organiske syrer eller mikroballoner, for dermed at opnå større agglomerater, som også udviser lysabsorption i området >8 /xm. De i disse blandinger som oxidationsmiddel anvendte alkalimetalsalte (natrium-, kalium-, lithiumnitrat) bevirker bl.a. også en sighalvirk-25 ning (farvning af flammen), som imidlertid ikke er egnet til at ændre den infrarøde absorption.Furthermore, from EP-A 37,515 it is known to combine smoke from halogen-20 donors / metal powders or phosphorous smoke with an additional secondary smoke of organic acids or microballoons, thus obtaining larger agglomerates which also exhibit light absorption in the range> 8 µm. The alkali metal salts (sodium, potassium, lithium nitrate) used in these mixtures cause, inter alia, also a six-half effect (staining of the flame), which, however, is not suitable for altering the infrared absorption.
Her udover indeholder de fleste pyrotekniske røgsatser ætsende, giftige eller stærkt sure komponenter såsom phosphorpentoxid, saltsyre, svovlsyre, titan- eller zinksalte, der i røgen forekommer i 30 koncentrationer, der er overordentlig skadelige for mennesker og planter. Ved tilsætning af metaloxider, puffersubstanser og ammoniumforbindelser har man derfor i de fleste hidtidige røgsatser sørget for, at den frembragte røg kun er så svagt sur som muligt eller neutral. Den foreliggende opfindelses opgave ligger derfor også i atIn addition, most pyrotechnic smoke kits contain corrosive, toxic or highly acidic components such as phosphorus pentoxide, hydrochloric acid, sulfuric acid, titanium or zinc salts found in the smoke at 30 concentrations which are extremely harmful to humans and plants. Therefore, in the addition of metal oxides, buffer substances and ammonium compounds, in most previous smoke rates, the smoke produced is only as slightly acidic as possible or neutral. The object of the present invention therefore lies in that
DK 164665 BDK 164665 B
3 modificere de kendte røgsatser på en sådan måde, at disse om muligt ikke reagerer surt.3 modify the known smoke rates in such a way that, if possible, they do not react acidically.
Disse opgaver løses på overraskende måde ved de i kravene beskrevne foranstaltninger, dvs. ved at der til i og for sig kendte røgsatser 5 baseret på halogendonorer samt metalpulvere og/eller -oxider eller baseret på rødt phosphor, idet røgsatsen endvidere indeholder alkalimetalsalte, endvidere tilblandes caesiumforbindelser, der ved afbrænding dispergeres og absorberer stråling i det infrarøde område.These tasks are surprisingly solved by the measures described in the requirements, ie. in addition, to known smoke rates 5 based on halogen donors as well as metal powders and / or oxides or based on red phosphorus, the smoke rate further containing alkali metal salts, further mixing cesium compounds which are dispersed and burning radiation in the infrared area.
Ved denne tilsætning af caesiumforbindelser nedsættes gennemsigtig-10 heden af røgen i IR-lys overraskende ganske betragteligt, især i infrarødt lys med bølgelængder på 3-5 eller 8-12 μπι, idet det endnu ikke har kunnet fastslås, hvorpå dette beror.By this addition of cesium compounds, the transparency of the smoke in IR light is surprisingly reduced considerably, especially in infrared light with wavelengths of 3-5 or 8-12 μπι, as it has not yet been established why this is due.
Eftersom caesiumsalte som bekendt i det nærinfrarøde område op til 12 μτη ikke udviser nogen absorptioner, der kan føres tilbage til sving-15 ning, og for hvilke caesiumionerne er ansvarlige (caesiumhalogenider udviser ingen, caesiumnitrat kun nitratgruppens svingning ved 7,2 jim), kan en direkte absorption af IR-lyset ikke komme på tale for effekten. Eftersom de anvendte mængder er relativt små sammenlignet med mængden af den samlede røgsats, svarende til kun gennemsnitlig 20 25%, og sammenlignet med de øvrige røgdannende komponenter kun er til stede i ringe mængde, kan forøgelsen af partikeltallet af det dis-pergerede system heller ikke gøres ansvarlig for effekten. Eftersom synkehastigheden og kondenserbarheden af de dannede røgskyer efter de hidtidige observationer ikke adskiller sig fra de tilsvarende røg-25 satser uden tilsætning af caesiumsalte, synes ej heller en forbedring af spredningsvirkningen af de frembragte partikler at være ansvarlig for effekten. Hvis det antages, at Stoke's lov gælder for disse partikler som en første tilnærmelse, dvs. at synkehastigheden er proportional med kvadratet af partikeldiameteren, ville en forøgelse 30 af partikeldiameteren fra 1 μ i sædvanlige røgsatser til 10 μ, der ville være nødvendig for en effektiv spredning i IR-området fra 8 til 12 μπι, betyde en forøgelse af synkehastigheden med en faktor 100.Since, as is well known in the near-infrared region, up to 12 μτη of cesium salts exhibit no absorbable tracings and for which the cesium ions are responsible (none of the cesium halides, the cesium nitrate exhibits only the nitrate group oscillation at 7.2 µm), a direct absorption of the IR light does not qualify for the effect. Since the amounts used are relatively small compared to the amount of the total smoke rate, corresponding to only an average of 20 25%, and compared to the other smoke-forming components are only present in small amounts, the increase in the particle number of the dispersed system cannot, either. be made responsible for the effect. Also, since the rate of sinking and condensability of the resulting smoke clouds does not differ from the corresponding smoke rates without the addition of cesium salts to date, no improvement in the scattering effect of the particles produced appears to be responsible for the effect. Assuming that Stoke's law applies to these particles as a first approximation, viz. that the sink rate is proportional to the square of the particle diameter, an increase of 30 the particle diameter from 1 µ in conventional smoke rates to 10 µ, which would be necessary for an effective spread in the IR range of 8 to 12 µπι, would increase the sink rate by a factor 100.
Det må derfor være forbeholdt videre undersøgelser at finde en tilfredsstillende teori for, hvorfor de pyrotekniske røgsatser ifølgeIt must therefore be reserved for further studies to find a satisfactory theory as to why the pyrotechnic smoke rates according to
DK 164665 BDK 164665 B
4 opfindelsen udviser en tilfredsstillende tæthed såvel i det synlige som i det infrarøde område.4 the invention exhibits a satisfactory density both in the visible and in the infrared range.
Den foreliggende opfindelse har endvidere haft den opgave, at forøge røgudbyttet fra phosphorholdige røgsatser.The present invention further has the object of increasing the smoke yield from phosphorus-containing smoke rates.
5 De sædvanligvis anvendte metaller magnesium og titan fører efter afbrænding af røgsatsen til et askeindhold på 60-70%.5 The commonly used metals magnesium and titanium lead to an ash content of 60-70% after burning the smoke rate.
Det lykkes overraskende nok at forøge effektiviteten af sådanne røgsatser ved i stedet for magnesium og titan at anvende en zirconi-um/nikkellegering, fortrinsvis med 70% zirconium og 30% nikkel. Aske-10 indholdet af sådanne satser kan derigennem sænkes til 5%. Tilsætning af bor virker i samme retning og forbedrer endvidere IR-absorptionen.Surprisingly, they succeed in increasing the efficiency of such smoke rates by using a zirconium / nickel alloy instead of magnesium and titanium, preferably with 70% zirconium and 30% nickel. The ash content of such rates can thereby be lowered to 5%. Addition of boron works in the same direction and further improves IR absorption.
Ved tilsætning af ammoniumchlorid kan effektiviteten forøges yderligere.By adding ammonium chloride, the efficiency can be further increased.
En stor fordel ved de ovenfor beskrevne røgsatser ligger i, at de er 15 passivt virksomme. Det betyder, at de ikke udviser nogen egen varme-toning og derfor ikke ændrer omgivelsesbilledet i infrarødt observationsudstyr.A major advantage of the smoke rates described above is that they are passively active. This means that they do not exhibit their own heat toning and therefore do not change the ambient image in infrared observation equipment.
I følgende eksempler sammenlignes en række røgsatser ifølge opfindelsen med tilsvarende røgsatser uden tilsætningen ifølge opfindelsen.In the following examples, a number of smoke rates according to the invention are compared with corresponding smoke rates without the addition of the invention.

Tændsatsen har følgende bestanddele: Magnesiumpulver (1,2 kg), berlinerblåt (0,9 kg), amorft bor (2,39 kg), pulverformet chlorparaffin 5 (0,8 kg) og sortkrudtsmel (4,71 kg). Magnesiumpulveret og berliner blåt forblandes; chlorparaffinen, opløst i 2 1 perchlorethylen, sættes dertil og blandes i. Det amorfe bor sættes til, og blandings-processen fortsættes i 5 minutter. Som sidste bestanddel blev sortkrudtet sat til, blandet med de andre bestanddele i 10 minutter, 10 tørret og presset ved 150 MPa.The ignition kit has the following components: Magnesium powder (1.2 kg), Berlin blue (0.9 kg), amorphous boron (2.39 kg), powdered chloro paraffin 5 (0.8 kg) and black powdered flour (4.71 kg). The magnesium powder and berlin blue are premixed; The chloro paraffin, dissolved in 2 L of perchloroethylene, is added and mixed. The amorphous boron is added and the mixing process is continued for 5 minutes. As the final ingredient, the black powder was added, mixed with the other ingredients for 10 minutes, 10 dried and pressed at 150 MPa.
Den samme blanding som ovenfor blev yderligere tilblandet 0,4 kg caesiumnitrat og blev på samme måde forarbejdet til presselegemer med en vægt på ca. 50 g. Som før blev i alt 20 presselegemer sammen med en tændsats i et hylster forenet til en ladning.The same mixture as above was further mixed with 0.4 kg of cesium nitrate and was similarly processed into press bodies weighing approx. 50 g. As before, a total of 20 press bodies, together with a spark plug in a casing, were united to a charge.
15 Til bedømmelse af røgvirkningen blev 3 til ca. 40°C opvarmede hvide plader anbragt i terrænet med en indbyrdes afstand på 10 m og blev på en afstand af 100 m observeret med infrarøde og optiske observations-apparater ved bølgelængder på 10 μτα, 3,5 μτα og 0,6 μτα. Røgladninger af den ovenfor beskrevne sammensætning blev ved hjælp af en driv-20 ladning skudt ud ca. 40-50 m foran målet, hvor der i løbet af sekunder dannede sig en 3-15 m høj og 25-40 m bred og dyb røgmur. Ved temperaturer på 22eC og en relativ luftfugtighed på 48% opnåedes de i følgende tabel anførte afdækningsforhold.15 To assess the smoke effect, 3 to approx. 40 ° C heated white plates placed in the terrain at a distance of 10 m and observed at a distance of 100 m with infrared and optical observation apparatus at wavelengths of 10 μτα, 3.5 μτα and 0.6 μτα. Smoke charges of the above-described composition were ejected with the aid of a drive charge. 40-50 m in front of the target, where within 3 seconds a 3-15 m high and 25-40 m wide and deep smoke wall formed. At temperatures of 22 ° C and a relative humidity of 48%, the coverage conditions given in the following table were obtained.
Med "særdeles god" forstås en afdækning på 95-100%, dvs. målet lader 25 sig ikke mere skelne fra baggrunden. Med "god" forstås en afdækning på 80-95%, dvs. målet kan knapt nok skelnes. Med "moderat” forstås en afdækning på 50-80%. Med "dårlig" forstås en afdækning på under 50%, ved hvilken målet tydeligt kan ses.By "extremely good" is meant a hedge of 95-100%, ie. the target can no longer be distinguished from the background. By "good" is meant a hedge of 80-95%, ie. the target can hardly be distinguished. "Moderate" means a hedge of 50-80% and "bad" means a hedge of less than 50%, by which the target can be clearly seen.
