MEDEL, FOR SLIPNING GENOM SPRUTNING, INNEHALLANDE EN BLANDNING AV GUARGUMMI, ALKALIBORAT OCH BORSYRA

摘要

A medium is disclosed useful in abrading or deburring metal parts by extruding the medium through openings which otherwise are quite often inaccessible. The medium comprises essentially guar gum, boric acid and borax, and one of the features of the invention is that the medium may be easily tailored to suit the size of the opening being abraded since optimum results are obtained using a less viscous medium in smaller openings and using a heavier viscosity of the medium when treating larger openings.
