Description of process
The test material
is sandwiched between the two plates and illuminated through the top plate
by a light source from a 45° angle. By measuring the amount of light
reflected at 0°, the normal, through the black and white sections of the
bottom tile respectively it is possible to calculate the opacity of the
material. Measurements are made as a function of the thickness by
squeezing the plates slowlt together, whilst continually monitoring the
reflectance from the two halves. The greater the hiding power of the best
material, the more similar the contrast ratio will appear over the two
halves of the tile. The contrast ratio will start to deviate as the film
thickness decreases, until the point is reached when the minimum thickness
for complete hiding is indicated.
Exemple applications
- Efficient use Titanium Dioxide in paints
- Optimisation of TiO2 / extender formulations
- Pigment dispersion and flocculation experiments
Simple operation
- Sample is placed in chamber
- Sample is squeezed between the two plates
- Contrast ratio and plate separation are mesured and recorded continuously
- Whole operation in under one minute
- Full computer control with user friendly Windows software
- Instantaneous results for analysis
- Animated data retrival
