Vynález řeší složení elektrolytu pro elektrochemické značení ložisek, případně jiného kovového povrchu.The invention solves an electrolyte composition for electrochemical marking of bearings or other metal surface.
Pro oLoktrochemickó značeni ložisek byly dosud používány různé druhy elektrolytu, např. podle autorského osvědčení č. 201 420 a 220 286, složené směsi ve vodě rozpustných alkoholů a alkalických solí anorganických kyselin. Elektrolyty tohoto složení nomají dosta točnou elektrickou vodivost, čímž se snižuje výkon zařízení pro elektrochemický popis nebo vlivem přítomnosti organických látek dochází také k zanášení šablony pro elektrochemický popis koloidními Částicemi, vznikajícími při elektrochemickém procesu. Navíc se příprava elektrolytu musí provádět při vyšší teplotě, protože některé složky elektrolytu nejsou dob ře rozpustné ve vodě.Various types of electrolyte have been used to locate electrochemical bearings to date, for example according to the author's certifications No. 201 420 and 220 286, a composite mixture of water-soluble alcohols and alkaline salts of inorganic acids. Electrolytes of this composition have sufficient electrical conductivity, thereby reducing the performance of the electrochemical description device or, due to the presence of organic substances, also clogging the electrochemical description template with the colloidal particles formed during the electrochemical process. Moreover, the preparation of the electrolyte must be carried out at a higher temperature, since some components of the electrolyte are not readily soluble in water.
Uvedené nedostatky řeší elektrolyt pro elektrochemické značení ložisek podle vynálezu, jehož podstata spočívá v tom, že obsahuje 0,8 až 1,5 % dusitanu sodného, 0,6 až 0,9 % dusičnanu sodného, 0,7 až 2,5 % vinanu sodnodraselného, 0,2 až 0,5 % benzoanu sodného a 1 až 5 % chloridu draselného, zbytek do 100 % hmot. tvoří voda. Počet potřebných látek je minimalizován a uvedené látky jsou všechny dobře rozpustné ve vodě, je proto zaručena jednoduchá a levná výroba elektrolytu.These drawbacks are solved by the electrolyte for electrochemical marking of bearings according to the invention, which consists in that it contains 0.8 to 1.5% sodium nitrite, 0.6 to 0.9% sodium nitrate, 0.7 to 2.5% tartrate 0.2 to 0.5% sodium benzoate and 1 to 5% potassium chloride; water. The number of substances required is minimized and the substances are all well soluble in water, thus making the production of electrolyte simple and inexpensive.
Nebezpečí vzniku koroze na ocelových materiálech je zabezpečeno vhodným množstvím dusitanu sodného. Dostatečná elektrická vodivost elektrolytu je zabezpečena přítomností chloridu draselného a dusičnanu sodného. Ostatní složky zajišťují vhodné prostředí elektrolytu, v němž výrazně působí dusitan sodný jako protikorozní složka. Elektrolyt neobsahuje organické látky, čímž je při elektrochemickém značení vyloučen vznik koloidních částic, které způsobují zanášení šablony. Složení elektrolytu na kovovém povrchu ložisek nepůsobí jako iniciátor koroze.The risk of corrosion on steel materials is ensured by an appropriate amount of sodium nitrite. Sufficient electrical conductivity of the electrolyte is ensured by the presence of potassium chloride and sodium nitrate. The other components provide a suitable electrolyte environment, in which sodium nitrite has a pronounced anti-corrosive effect. The electrolyte does not contain organic substances, thereby eliminating the formation of colloidal particles that cause clogging of the template during electrochemical labeling. The electrolyte composition on the metal bearing surface does not act as a corrosion initiator.
Elektrolyt podle vynálezu byl odzkoušen při dalších zkouškách značení ložiskových kroužků a jeho použití je schváleno po stránce hygienické. Pomocí příkladu je uvedeno složení elektrolytu, ve kterém je provedena optimalizace dávek jednotlivých složek elektrolytu pro docílení největších účinků: 1,2 g dusitan sodný, 0,6 g dusičnan sodný, 1,7 g vinan sodnodraselný, 0,4 g benzoan sodný, 1,5 g chlorid draselný do 100 g vody.The electrolyte according to the invention has been tested in further tests of bearing ring marking and its use is sanitary approved. An example of an electrolyte composition is to optimize the doses of the individual electrolyte components to achieve the greatest effects: 1.2 g sodium nitrite, 0.6 g sodium nitrate, 1.7 g sodium potassium tartrate, 0.4 g sodium benzoate, 1 g 5 g potassium chloride to 100 g water.
Takto připravený elektrolyt se přímo použije pro elektrochemické značení ložisek.The electrolyte thus prepared is used directly for electrochemical marking of bearings.
