Description
25 30 5232997 och denna lilla mängd bly fungerade som avkoppringsmedel. Nuvarande lösning mot kopparbeläggning är att integrera ett avkoppringsmedel i krutet. Avkoppringsmedlet tar bort kopparavsåttriingama utan att skada eldröret eller räfflingen. 5302997 and this small amount of lead acted as a decoction agent. The current solution against copper coating is to integrate a decoction agent into the powder. The decongestant removes the copper deposits without damaging the barrel or the rake.
Ett vanligt avkoppringsmedel är en folie av bly som placeras mellan drivladdningen och projektilen. När drivladdningen antänds så förångas blyet och sprids in i kopparen. Den legering som uppstår är spröd och lättkrossad. Kombinationen av hettan som genereras av det brinnande krutet och den mekaniska rörelsen hos drivgasema separerar den spröda bly/kopparlegeringen från eldrörets yta. Det krossade skräpet sveps ut ur eldrörsmynningen med krutgasema.A common decoction agent is a lead foil that is placed between the propellant charge and the projectile. When the propellant charge ignites, the lead evaporates and spreads into the copper. The resulting alloy is brittle and easily crushed. The combination of the heat generated by the burning gunpowder and the mechanical movement of the propellants separates the brittle lead / copper alloy from the surface of the barrel. The crushed debris is swept out of the barrel mouth with the gunpowder gases.
En andra teori varför blyfolie är effektivt såsom avkoppringsmedel är att den hetta som genereras av det brinnande krutet smälter blyfolien. Smält bly kommer i kontakt med kopparavsättningen och löser upp kopparen varpå den kopparinnehållande blylösningen drivs ut såsom vätska ur myrmingen med krutgasema.A second theory why lead foil is effective as a cupping agent is that the heat generated by the burning powder melts the lead foil. Molten lead comes into contact with the copper deposit and dissolves the copper, after which the copper-containing lead solution is expelled as a liquid from the myrrh with the gunpowder gases.
Metalliskt bly och blyföreningar är effektiva avkoppringsmedel, men de är också gifiiga för människor som arbetar nära vapnen. Det finns således ett behov av ett blyfritt avkoppringsmedel.Metallic lead and lead compounds are effective means of relaxation, but they are also beneficial for people working near weapons. There is thus a need for a lead-free decongestant.
Bland de blyfria avkoppringsmedlen som har föreslagits finns vismut, vismutsubkarbonater (BiCo.sub3) tenn och tennlegeringar. Vismutföreningar är mycket spröda och inte ens metallisk vismut kan rullas till en tunn folie såsom bly.Among the lead-free relaxants that have been proposed are bismuth, bismuth subcarbonates (BiCo.sub3) tin and tin alloys. Bismuth compounds are very brittle and not even metallic bismuth can be rolled into a thin foil such as lead.
Vismutlegeringar med andra metaller kan rullas till en folie, men legeringarna är mycket dyra och mindre effektiva såsom avkoppringsmedel. Det finns också lösningar där man använder specialgjorda pellets av vismut med nitrocellulosa som bindemedel, som tillsätts drivladdningen.Bismuth alloys with other metals can be rolled into a foil, but the alloys are very expensive and less effective as cupping agents. There are also solutions that use specially made pellets of bismuth with nitrocellulose as binder, which are added to the propellant charge.
Det kvarstår därför ett behov av en metod som effektivt integrerar ett blyfi-ítt avkoppringsmedel i krutet. Att inkorporera avkoppringsmedlet i krutkompositionen är både billigare och enklare än att tillsätta ett specialgjort avkoppringsmedel till laddningen. 10 15 20 25 523 997 ._ ,,g, ß " .mßvm SAMMANFATTNING AV UPPFINNINGEN Ett avkoppringsmedel har tagits fram som är integrerat i krutet för att avlägsna koppar från räfflingen av ett eldrörs insida. Avkoppringsmedlet består huvudsakligen av en blyfri pulvertillsats blandad med de övriga krutkomponentema. Vi har upptäckt att en blandning av tenn och vi smut är ett mycket bra avkoppringsmedel. I syrmerhet när relationen mellan term och vismut är 10 - 62 % Sn och 90 - 38 % Bi. Vid speciellt proportionerna 42 % Sn och 58 % Bi är smältpunkten för denna kombination 138 grader C, vilket är mycket lägre än för respektive komponent. Användbara är alla typer av vismut- och tennföreningar. Lämpligen valda ur den grupp som består av metallisk vismut, vismutlegeringar, vismutsföreningar, metallisk tenn, termlegeringar och tennföreningar. Antingen så förångas vismut och term eller så bildas en vätska när krutet antänds, vilket antingen spräcker eller upplöser kopparavsättningama vilket underlättar borttagandet.There is therefore still a need for a method that effectively integrates a lead tt-a detergent into the powder. Incorporating the decongestant into the gunpowder composition is both cheaper and easier than adding a custom decongestant to the charge. SUMMARY OF THE INVENTION A decongestant has been developed which is integrated into the powder to remove copper from the inside of a barrel. The decongestant consists mainly of a lead-free powder additive mixed with the We have discovered that a mixture of tin and we smut is a very good decoction agent, especially when the ratio between term and bismuth is 10 - 62% Sn and 90 - 38% Bi, especially at the proportions 42% Sn and 58% Bi is the melting point of this combination 138 degrees C, which is much lower than for each component.Useful types of bismuth and tin compounds are useful.Suitably selected from the group consisting of metallic bismuth, bismuth alloys, bismuth compounds, metallic tin, thermal alloys and tin compounds Either bismuth and term evaporate or a liquid is formed when the powder is ignited, which either cracks or dissolves the copper deposits, which facilitates removal. agandet.
I enlighet med detta är ett syfte med uppfinningen att tillföra ett väsentligen blyfiitt avkoppringsmedel som är inkluderat i krutet. Det ligger i uppfinningens natur att avkoppringsmedlet är en del av krutet och att det är homogent fördelat.Accordingly, an object of the invention is to add a substantially lead-containing decoction agent which is included in the powder. It is in the nature of the invention that the decongestant is part of the powder and that it is homogeneously distributed.
Det är en fördel med uppfinningen att avkoppringsmedlet fördelas till och genom eldröret med krutgaserna. När avkoppringsmedlet är inkorporerat i krutet betyder det också att krutgaserna alltid innehåller samma mängd avkoppringsmedel.It is an advantage of the invention that the decongestant is distributed to and through the barrel with the gunpowder gases. When the decoction agent is incorporated into the powder, it also means that the powder gases always contain the same amount of decoction agent.
Den största fördelen med derma uppfinning är att avkoppringsmedlet alltid finns där, det gör tillverkningen av drivladdningar enklare och billigare. Det behövs inga extra behållare för specialgjord substans för avkoppring.The main advantage of this invention is that the decongestant is always there, it makes the manufacture of propellant charges easier and cheaper. No extra container is needed for specially made substance for relaxation.
