Description

Mahle Komm.-Ges. in Stuttgart-Bad Cannstatt Verfahren zum Aufbringen farbiger Schutzschichten auf Gegenstände aus Magnesium oder Magnesiumlegierungen eines organischen Lösungsmittels (z. B. Trichloräthylen oder Alkohol) getaucht werden, in ,dem außerdem noch Harz oder Kunstharz gelöst ist.Mahle Komm.-Ges. in Stuttgart-Bad Cannstatt Process for applying colored protective layers to objects made of magnesium or magnesium alloys an organic solvent (e.g. trichlorethylene or alcohol) in which resin or synthetic resin is also dissolved.

Xlit Hilfe dieses Verfahrens aufgebrachte Farblacl:schichten gewähren einen erheblich verbesserten Korrosionsschutz, da sie sich bei Erwärmung nicht verändern. Es verdampft lediglich <las Lösungsmittel, während die Harz- oder Kunstharzschicht auch bei höheren Temperaturen vollständig erhalten bleibt. Dadurch ist das Verfahren auch wirtschaftlicher als das bekannte Färbverfahren mit den in Fettstoffen gelösten Farbstoffen, bei dem der größte-, Teil des aufgewendeten Fettes beim Erwärmen verloreiigelit.Apply layers of paint using this process significantly improved corrosion protection, as they do not change when heated. It only evaporates the solvent while the resin or synthetic resin layer is completely retained even at higher temperatures. This is the procedure also more economical than the known dyeing process with those dissolved in fatty substances Dyes in which most of the fat used is lost when heated.

Die Ansaugfähigkeit der Poren der vorbehandelten Gegenstände kann dadurch noch verbessert werden, daß man die Gegenstände vor dem Eintauchen in die Farblösung erwärmt, und zwar vorzugsweise auf etwa 3o bis 5o° C. Eine Erwärmung auf ähnliche Temperaturen ist auch nach dein Herausnehmen der Gegenstände aus der Farblösung vorteilhaft, um die Verdampfung des Lösungsmittels zu beschleunigen und eine gewisse Härtung der Lackschicht zu erzielen.The absorbency of the pores of the pretreated objects can can be improved by the fact that the objects before immersion in the Color solution heated, preferably to about 3o to 5o ° C. A warming the temperature is similar even after you have removed the objects from the Color solution advantageous to accelerate evaporation of the solvent and to achieve a certain hardening of the lacquer layer.
