Definitions

  • the present invention relates to a method for cleaning the barrel of a firearm as presented in claim 1.
  • bullet remnants means the metal residue left in the barrel from bullets, such as, in the case of commonly used bullets containing copper, residue of copper, possible copper compounds and other alloyed metals, e.g. copper and zinc residue and, in the case of lead bullets, lead residue.
  • the object of the present invention is to eliminate the drawbacks referred to above.
  • a special object of the invention is to produce an effective cleaning method of a new type that reduces the need for mechanical cleaning and thus significantly extends the service life of the barrel.
  • a further object of the invention is to produce a new type of cleaning method that is faster and more user- friendly than earlier methods.
  • the invention is based on the unexpected observation made during investigations that bullet residue can be removed by using a foam that, in the case of bullets containing copper, contains an alkaloamine and, in the case of bullets containing lead, a nitrate salt. Thanks to the invention, a method has now been discovered that makes it possible to effectively and quickly remove the metal residue left by bullets in a barrel, without damaging the steel of the barrel.
  • ammonia can also be used for the cleaning of a barrel because the foam prevents evaporation of ammonia, so the cleaning agent does not lose any of its effectiveness.
  • nitrate salt has now been used for the first time as a material that chemically removes bullet residue. It was observed during investigations carried out that lead residue in a barrel reacts due to nitrate salt in a way that allows the lead to be removed from the barrel surface without mechanical scrubbing.
  • the nitric salt used is preferably an inorganic nitrate, such as alkaline nitrate, alkaline earth nitrate or ammonium nitrate, especially sodium nitrate.
  • the cleaning can be performed by using any substance that forms a foam, preferably a consistent foam, that contains e.g. exclusively nitrate salt, in which case it is applicable for the cleaning of firearms using lead bullets.
  • a consistent foam containing an alkanolamine and/or a nitrate salt is used, in which case the method is applicable for the cleaning of both firearms using lead bullets and firearms using copper/copper compound bullets.
  • the alkanolamine can also be used for the adjustment of the pH of the solution to an alkalic value in connection with solutions containing a nitrate salt.
  • the alkanolamine is preferably monoethanolamine or diethanolamine or a compound of these, especially monoethanolamine.
  • a foam is used that contains about 1 - 80 w-%, preferably about 20 - 70 w-% nitrate salt, such as sodium nitrate, and/or about 1 - 70 w-%, preferably about 1 - 30 w-%, e.g. 2 - 25 w-% alkanolamine, such as monoethanolamine or diethanolamine.
  • the amount of tenside used in the cleaning method is e.g. under 50 w-%, e.g. about 0.1 - 25 w-% of the composition, depending on the intended application.
  • the foam used in the cleaning method may further contain about 1 - 90 w-% added water.
  • the amount of water may be e.g. 5 - 60 w-%.
  • an amount of under 15 w-%, e.g. about 0.1 - 3 w-%, of sodium salt of m-nitrobenzenesulfonic acid has been added to a composition containing alkanolamine to assist in removing from the barrel surface the reaction products formed by residue from bullets containing copper.
  • composition used in the method of the invention may additionally contain an amount of about 0.1 - 30 w-%, e.g. 1 - 10 w-%, of a barrel protecting substance, such as commonly known arms oil or preferably so-called cutting lubricant, which may be of semi-synthetic or synthetic type and which prevents copper from sticking to the barrel.
  • a barrel protecting substance such as commonly known arms oil or preferably so-called cutting lubricant, which may be of semi-synthetic or synthetic type and which prevents copper from sticking to the barrel.
  • the agent used for barrel treatment may be a water-mixable substance or it can be emulsified in water using e.g. a tenside and/or solvent, such as butoxyethanol.
  • composition of substances used in the method of the invention can be implemented in any suitable form.
  • the composition is in the form of a foaming liquid or, suitably, in the form of a spray sprayable as a foam, in which case it is packed in a container equipped to produce a spray, together with propellants if required.
  • the composition may also contain an agent that increases viscosity.
  • Example 1 Producing a composition of substances for use in the cleaning method of the invention.
  • a cleaning solution composed according to one of the following alternatives is prepared: Components w-% preferred composition A B C D E coconut diethanolamide 0.1-50 4 25 2 3 monoethanolamine 0-70 1-30 25 2 15 70 sodium nitrate 0-70 20-70 40 20 70 40 methylpyrrolidone 0-30 1-15 5 15 5 10 5 1-butoxyethanol 0-30 1-15 5 15 5 10 5 sodium salt of m-nitrobenzenesulfonic acid 0-30 0.1-3 1 3 2 10 semi-synthetic cutting lubricant 0-30 1-10 10 10 10 10 water added 0-60 1-30 10 10 12 10
  • the sodium nitrate is solved in the water added. It can also be added to other components in the form of a rich water solution. Instead of monoethanolamine, other alkanolamines can also be used, such as diethanolamine.
  • the formulation is performed by using a tenside in an amount of e.g. about 0.1 - 30 w-%.
  • the amount of tenside used is e.g. 0.1 - 4 w-%.
  • the concentrations of active components are selected e.g. on the basis of the length of time the cleaning agent is to be allowed to act in the barrel. This action time may vary e.g. between 0.1 - 30 min., whereupon the composition is removed by using a plug of a medium, e.g. a felt plug.
  • the finished composition has an alkalic pH value.
  • the cleaning method of the invention is less hazardous to the user and the environment than earlier methods and the composition emits no toxic gases as compared with previous compositions. Moreover, consisting of cheap components, it is advantageous in respect of cost.
  • the composition used does not suffer any loss of efficiency during storage or use. Furthermore, the composition used in the method protects the barrel, and the addition of cutting oil has the effect that a smaller amount of bullet residue, such as copper, sticks to the barrel surface.
  • the cleaning method of the invention is applicable for the cleaning of the barrel part of a firearm of any type and any size.
  • composition of the foam used in the method Components w-% monoethanolamine ca.25 methylpyrrolidone ca. 5 1-butoxyethanol ca. 5 sodium salt of m-nitrobenzenesulfonic acid ca. 1 coconut diethanolamide ca. 4 water added ca. 50 semi-synthetic cutting lubricant ca. 10
  • the composition was prepared in the form of a spray. To clean a firearm, the foaming alkalic composition was sprayed into the barrel and allowed to act for ca. 10 min., whereupon it was removed by pushing a felt plug through the barrel.
  • the firearm cleaning method was tested in field conditions during half a year. It was established that the cleaning method worked in cold and hot weather. Moreover, the method was found to be effective and easy to use.
