Title:
METHOD FOR MEASURING CONCENTRATION AND DISTRIBUTION OF CARBON BLACK IN OTHER MATERIAL CONTAINING RUBBER COMPOUND AND CARBON BLACK, AND DEVICE FOR EXECUTING METHOD THEREOF
Document Type and Number:
Japanese Patent JP3662953
Kind Code:
B2
Abstract:

PURPOSE: To improve the method and device based on the TRELIBS principle so that the concentration and distribution of carbon black in a rubber compound can be determined.
CONSTITUTION: The surface 1a of a rubber plate 1 is scanned by an end region 4a of a laser beam 4 emitted from a pulse-laser unit 5. A radiation 3 of a plasma 4c formed on a measuring point 4b by a focusing laser beam is supplied to a spectroscope 10 having a diffraction gating, and evaluated by a computer 13. The measurements of two types of spectral intensities generated by two laser pulses are performed with different, constant time lags tv1 and tv2. In the first measurement, the intensity Ic of a spectral line of a reference element (carbon), and the intensity IA.n of spectral lines of all other analytical elements, are determined, and from the intensities a ratio of IA.n/Ic is determined. In the second measurement, the intensity Ic' of a spectral line of the reference element and the intensity IA.n' of at least one spectral line of the other analytical element, are determined, and from these intensities a ratio of the intensities is determined when necessary.
