(54) Elektrolyt pre elektrochemické značenie popisu(54) Electrolyte for electrochemical labeling
Vynález sa týká zloženia elektrolytu, ktorý je vhodný na elektrochemické značenie popisu na kovový povrch, zvláSť na povrch ložísk.The invention relates to an electrolyte composition suitable for the electrochemical marking of a description on a metal surface, in particular on a bearing surface.
V súlade so světovým stavom techniky sa v ložiskovej výrobě stále viao presadzuje elektrochemické značenie popisu nutných údajov na povrchu výrobkov. Jedná sa o náhradu deformačného popisu razením, připadne ručného značenla pomocou agresívnych, silné kyslých a zdraviu Škodlivých elektrolytov.In accordance with the state of the art, electrochemical marking of the description of the necessary data on the surface of products is increasingly promoted in bearing production. It is a replacement of the deformation description by punching, eventually hand marking with aggressive, strong acid and harmful electrolytes.
Na elektroohemioké značenie popisu na kovovom povrohu je známe v praxi niekoPko zložení elektrolytov, napr. zmes dusičnanu sodného, alebo draselného a vody, zmes dusičnanu a dusitanu sodného, alebo draselného a vody, zmes dusičnanu draselného, dusitanu sodného, vinanu sodno-draselného, trietanolamínu a vody, zmes chloridu amonného, vanadičnanu amonného, komplexónu III a vody, zmes dusičnanu sodného, komplexónu III, citranu draselného, kyseliny vinnéj, chloridu železitého a vody.Several electro-electrolyte compositions, e.g. a mixture of sodium or potassium nitrate and water, a mixture of sodium or potassium nitrate and nitrite and water, a mixture of potassium nitrate, sodium nitrite, sodium potassium tartrate, triethanolamine and water, a mixture of ammonium chloride, ammonium vanadate, complexon III and water, a mixture of nitrate sodium, complexon III, potassium citrate, tartaric acid, ferric chloride and water.
Nevýhodou uvedených zložení elektrolytov je ich korózna a v niektorýoh prípadoch aj výrazná biologická Škodlivost’. Okrem toho tieto elektrolyty majú len malú, připadne nedostJktočnú sohopnost* zabraňovat* hromadeniu splodín elektrochemickéj reakoie v mieste popisu.The disadvantage of these electrolyte compositions is their corrosion and, in some cases, significant biological harm '. In addition, these electrolytes have only a small or possibly insufficient ability to prevent the accumulation of electrochemical reactive gases at the site of the description.

Uvedené nedostatky rieši elektrolyt na elektroohemioké značenie popisu podl’a vyná lezu, ktorého podtata spočívá v tom, že pozostáva z 0,5 až 50 % hmotnostných glycerínu, m 0,05 až 15 # hmotnostných mono-, dl-, tri-, s výhodou polyetylénglykolu s priemernou molekulovou váhou 1 500, alebo mono-, di-, tripropylénglykolu,z 0,8 až 22 % hmotnostných dusičnanu draselného alebo sodného, z 0,05 až 3,7 % hmotnostných henzoanu alebo salyoilanu sodného alebo draselného, z 0,1 až 3,6 % hmotnostných hexametyléntetramínu, z 0,05 až *3 hmotnostnýoh alkalického dusitanu, napr. dusitanu sodného, z 0,1 až 1,2 % hmotnostných alkanolamlnu, napr. monoetanolamínu, z 0,15 až 2,3 % hmotnostnýoh henztriazolu a zvyšok do 100 % hmotnostnýoh tvoří voda.The above-mentioned drawbacks are solved by an electrolyte for electro-chemical marking according to the invention, which consists in that it consists of 0.5 to 50% by weight of glycerin, 0.05 to 15% by weight of mono-, dl-, tri-, s- preferably polyethylene glycol with an average molecular weight of 1,500, or mono-, di-, tripropylene glycol, from 0.8 to 22% by weight of potassium or sodium nitrate, from 0.05 to 3.7% by weight of sodium or potassium henzoate or salyoilane, of 0 From 1 to 3.6% by weight of hexamethylenetetramine, from 0.05 to 3% by weight of an alkali nitrite, e.g. sodium nitrite, from 0.1 to 1.2% by weight of alkanolamine, e.g. monoethanolamine, from 0.15 to 2.3% by weight of henztriazole and the remainder to 100% by weight is water.
