PENETRANT FOR THE COLOR CAPILLARY DEFECTOSCOPY Russian patent published in 2006 - IPC G01N21/91 C09K11/06 

FIELD: capillary defectoscopy; compositions of the color penetrants.

SUBSTANCE: the invention is pertaining to the color capillary defectoscopy, in particular, to the compositions of the color penetrants applied to the color control over the items of the high-duty. The penetrant contains the mixture of the following composition: xanthene dyes of the yellow-orange fluoresceine and red-dark blue rhodamine of 3-6 %, the surfactant of 10-40 %, the rest - the dissolvent. The ratio of the mixture of the yellow-orange and the dark blue - red dyes compounds 1:2, as the surfactant use neonol or syntanol. The technical result of the invention is creation of the color penetrant of the lowered volatility, the reduced flammability, the extra-high sensitivity ensuring detection of the minimal flaw with the opening width of 0.5-1 microns and the improved reliability and stability of the monitoring of the items in conditions of repairs and operation.

EFFECT: the invention ensures detection of the minimal flaw with the opening width of about 1 micron, improved reliability and stability of the monitoring of the items in conditions of repairs and operation.
