Description
En vue de la production de compositions traçantes colorées, on comprime ensemble en pyrotechnie des sels appropriés avec des métaux actifs, comme le magnésium et l'aluminium, en présence d'agents liants (par exemple du shellac9 etc) et de composés riches en oxygène (nitrate, chlorate, etc). Les compositions traçantes sont alors pourvues de dispositifs de mise à feu et trouvent des applications pour les fusées lumineuses, les munitions traçantes, etc.
Comme constituants colorants on a d'abord utilisé les nitrates des métaux alcalino-terreux, ensuite les halogénures à pouvoir illuminant beaucoup plus intense. Finalement on s'est rendu compté aussi que les halogénures métalliques
à lumière colorée ne doivent pas se présenter tels quels dans la composition tragante, mais seulement à l'état naissant au cours de la combustion de la composition traçante. On a utilisé des acides gras et des acides sulfoniques aromatiques qui
<EMI ID=1.1>
On vient de découvrir que les échangeurs de cations halogènes qui sont chargés avec des cations à lumière colorée comme par exemple les ions calcium;, les ions strontium, les ions baryum, les ions thallium, en mélanges avec des métaux actifs ou encore sans ceux-ci avec addition de nitrates, chlorates, etc, peuvent être élaborés en des compositions traçantes.
Ces compositions traçantes offrent comme progrès technique par rapport à l'état actuel de la technique les avantages suivants :
L'intensité lumineuse peut être modifiée à volonté en fonction de la charge de la résine échangeuse d'ions en cations à lumière colorée, par exemple des ions calcium, des ions strontium, des ions baryum, des ions thallium. Les résines échangeuses complètement chargées produisent des compositions traçantes à pouvoir éclairant étonnant.
L'addition, toujours nécessaire jusqu'ici, d'agents liants à la composition traçante n'est plus nécessaire étant donné que la résine se comporte en même temps comme agent liant.
Les résines échangeuses sont des corps difficilement combustibles.
Elaborées en compositions traçantes, elles possèdent lors de la combustion une durée de combustion étonnamment longue. Par une combinaison de divers
<EMI ID=2.1>
encore avec des cations différents, on peut obtenir des compositions traçantes de couleur.différente et d'intensité colorée différente.
<EMI ID=3.1>
échangeuses d'ions halogénées sont chargées jusqu* à saturation avec des cations
à lumière colorée, comme par exemple des ions calcium, des ions strontium, des ions baryum, des ions thallium.
For the production of colored tracing compositions, suitable salts with active metals, such as magnesium and aluminum, are compressed together in pyrotechnics, in the presence of binding agents (for example shellac9 etc.) and oxygen-rich compounds. (nitrate, chlorate, etc.). The tracing compositions are then provided with firing devices and find applications for light flares, tracer ammunition, etc.
As coloring constituents, nitrates of alkaline earth metals were used first, followed by halides with a much more intense illuminating power. Finally we also realized that the metal halides
with colored light should not appear as such in the tracing composition, but only in the nascent state during the combustion of the tracing composition. Fatty acids and aromatic sulfonic acids were used which
<EMI ID = 1.1>
We have just discovered that the halogen cation exchangers which are charged with colored light cations such as, for example, calcium ions, strontium ions, barium ions, thallium ions, in mixtures with active metals or even without them. these with the addition of nitrates, chlorates, etc., can be produced in tracing compositions.
These tracing compositions offer, as technical progress over the current state of the art, the following advantages:
The light intensity can be varied at will depending on the charge of the ion exchange resin in colored light cations, for example calcium ions, strontium ions, barium ions, thallium ions. Fully charged exchange resins produce tracing compositions with amazing illuminance.
The addition, which has hitherto always been necessary, of binding agents to the tracing composition is no longer necessary since the resin behaves at the same time as a binding agent.
Exchange resins are hardly combustible substances.
Developed in tracing compositions, they have a surprisingly long combustion time during combustion. By a combination of various
<EMI ID = 2.1>
again with different cations, it is possible to obtain tracing compositions of different color and of different color intensity.
<EMI ID = 3.1>
halogenated ion exchangers are charged to saturation with cations
with colored light, for example calcium ions, strontium ions, barium ions, thallium ions.
