Abstract
An instrument for measuring volume solids of a paint sample is described.
Claims19
An instrument to measure the volume solids of a paint sample, the instrument comprising:
- sensor means arranged to scan both the surface of a paint sample on a substrate surface moving with respect to the sensor means and an exposed reference surface of the substrate along the same line during the same scan, and to emit and detect signals reflected from the surface of the paint sample and the exposed reference surface of the substrate along the line for generating data sets including data indicative of a position of the surface of the paint sample when wet and a second position of the paint sample when dry, and to detect the position of the exposed reference surface of the substrate, in which the scan line of the paint sample and the exposed reference surface of the substrate when wet is in the same location as the scan line of the paint sample and the exposed reference surface of the substrate when dry, the sensor means being located so as to be distanced from the paint sample for the emission and detection of the signals;
- and
- processing means for processing the data sets generated by the sensor means to determine the volume solids of the paint sample.
A method for measuring volume solids of a paint sample, the method comprising:
- providing a drying means to fully dry a paint sample;
- providing sensor means to emit and detect signals reflected from the surface of the paint sample on a substrate along a line, for generating data sets consisting of data indicative of a position of the surface of the paint sample when wet and when dry and a position of at least one exposed reference surface of the substrate, in which the scan line of the at least one exposed reference surface of the substrate and the paint sample when wet is in the same location as the scan line of the same at least one exposed reference surface and paint sample when dry;
- while the substrate is moving with respect to the sensor using the sensor means to scan along the line to scan both the paint sample and the exposed reference surface to generate the data set for the paint sample when wet;
- drying the paint sample using the drying means;
- while the substrate is moving with respect to the sensor using the sensor means to scan along the line to scan both the paint sample and the exposed reference surface to generate the data set for the paint sample when dry, the sensor means being distanced from the paint sample to emit and detect the signals;
- and
- processing the data sets to determine the volume solids of the paint sample.
