Description

Verfahren zur Herstellung von stabilen, aufgraphitierten Schmierfetten Bislang geschah ,die Aufgraphitierumg vorn Schmierfetten zumeist auf kaltem Wege, indem Graphitpulver, Graphitpuder oder Graphitölkonzentrate vermittels Knetmaschine den Fetten einverleibt wurde. Wurden die Fette erhitzt und diesen sodann Graphitpulwer, Gräphitpuder oder Graphitölkonzentrate unter Umrühren beigemischt, so ließ sich schon vor dem Erkalten der so behandelten Fette ein Absetzen des Graphits nicht vermeiden. Um diesen Übelstand zu beheben, werden erfindungsgemäß Fette, Graphitpulver, Graphitpuder oder Graphitölkonzentrate und -Methylalkohol allmählich unter stetem Umrühren bis auf 175' oder höher erhitzt, bLS1 der Methylalkohol verflüchtigt oder nach bekanntem Verfahren zur Wiederverwendung zurückgewannen ist.Process for the production of stable, graphitized lubricating greases So far it has been the case that the graphing of lubricating grease is mostly done in a cold way, by using graphite powder, graphite powder or graphite oil concentrates by means of a kneading machine was incorporated into the fats. If the fats were heated and then graphite powder, Graphite powder or graphite oil concentrates mixed in with stirring, so it could be The graphite does not settle before the treated fats have cooled down avoid. In order to remedy this drawback, fats, graphite powder, Graphite powder or graphite oil concentrates and methyl alcohol gradually under constant Stirring heated to 175 'or higher, the methyl alcohol will volatilize or bLS1 is recovered for reuse by a known method.

Da der Methylalkohol die beigefügten Graphitteilchen weiter aufteilt und stabilisiert, so entsteht infolge der erhöhten Anzahl von Graphitsubnlikro#nen im Schmierfett ein. Graphitfett mit erhöhter Schmierwirkung, welches auch zum Schmieren feinster Maschinenteile und Kugellager verwendet werden kann.Because the methyl alcohol further divides the attached graphite particles and stabilized, is the result of the increased number of graphite submicro # ns in the grease. Graphite grease with increased lubricating effect, which is also used for lubricating finest machine parts and ball bearings can be used.
