Definitions

• the invention relates to a cleaning agent for firearm barrels based on ammonia or amine compounds, in particular for the removal of bullet abrasion.
• the invention is based on the object of providing a cleaning agent of the type mentioned which is simpler to use and less dangerous and which allows longer storage with proper cleaning of the gun barrels.
• the ammonia gas can only evaporate to a very small extent, so that only a small amount of harmful and unpleasant steam is emitted in relation to the amount of ammonia. This also makes it easier to store the cleaning agent, since gel adhering to the closure point of a container prevents the loss due to the evaporation of ammonia. In this way, the effectiveness of the cleaning agent is maintained for a very long time.
• the addition of the potassium hydroxide solution enables the detergent to be used much more effectively with lead rubbers.
• Alkali and alkaline earth metal salts of ethylenediaminetetraacetic acid or potassium oleate and salts of naphthenic acid can also be added to the cleaning agent in order to improve the cleaning effect.
• warning dye gives the advantage that residues inside the barrel can be easily recognized and removed.
• the cleaning agent according to the invention adheres very well to the inside wall of the barrel and has a very strong effect there.
• glycerin When glycerin is added, the gel is prevented from drying out and a certain degree of slipperiness is achieved, which makes application easier.
• An additional mechanical grinding and polishing effect can be achieved by adding an abrasive and polishing agent with a mechanical effect to the gel.
• This grinding and polishing agent can be formed by cerium oxide or finely powdered silicon dioxide.
• carboxyvinyl polymer is mixed with about 65% water, after which about 25% aqueous ammonia solution is added to form a gel.
• aqueous ammonia solution is added to form the starting gel.
• about 8% glycerol and / or fluorescein sodium or another conspicuous warning dye is added to this gel.
• Example 2 The same production steps as in Example 1 are used to prepare the starting gel, but up to 25% of triethanolamine or diethanolamine are added instead of the amount of 25% aqueous ammonia solution.
• Example 2 The same production steps as in Example 1 are used to prepare the starting gel, but in place of the aqueous ammonia solution in to the amount of 25%, 25% of a 15% Na 2 CO 3 solution (soda) or K 2 CO 3 solution (potash).
• Example 2 The same production steps as in Example 1 are again used to produce the starting gel, but the 25% ammonia solution is replaced by 10% ethylenediamine and a further 15% water.
• ammonia gas can also be passed through the mixture of carboxyvinyl and water, the gas being taken up to a certain concentration. The remaining manufacturing steps remain the same, including the addition of the glycerin and, if necessary, the warning dye.
• a carboxyvinyl polymer was used as the basis for the starting gel.
• other gelling agents can also be used, for example carboxymethyl cellulose.
• ammonia solution or triethanolamine, diethanolamine or ethylenediamine or soda or potash is not required for the gel formation, but can be replaced by water.
• An aqueous solution of KOH in water is prepared by dissolving about 3 to 4 g of KOH in 15 ml of water. This aqueous solution is mixed into an amount of 85 g of the starting gel, the amount of water for the preparation of this starting gel possibly being reduced in order to achieve a correspondingly higher or lower viscous gel.
• the starting gel using the carboxyvinyl polymer as such already has an excellent cleaning action and as such already dissolves abrasion from copper and copper compounds such as e.g. Tombac. Acidic powder residues are also neutralized. The addition of the aqueous solution of KOH also causes the lead rubbings to dissolve.
• Potassium oleate is added to the starting gel either in place of the aqueous solution of KOH according to Example 6 or in addition to it in an amount of 16%. This also effectively removes rust deposits.
• alkali metal and / or alkaline earth metal salts of ethylenediaminetetraacetic acid can be added to the starting gel in an amount of at least 5%.
• an abrasive and polishing agent with mechanical action can be added to the gel.
• This grinding and polishing agent can be, for example, cerium oxide or very finely powdered silicon dioxide.
