Particle Size Analysis
An important quality test is the particle size analysis. White Carbonates takes pride in possessing a laser particle size analyzer from the best company making them, Malvern. It gives particle size of powdered material along with particle size distribution, which is essential in selecting the right grade of ground calcium carbonate.
Whiteness
Natural minerals are present in different colors, depending on their origin and grinding conditions. White Carbonates has Konica Minolta Color Reader. Since color variations of white are especially obvious, it is increasingly important to control the color.
Opacity
White Carbonates has a well-defined system in the application side of raw materials. White Carbonates has the opacity meter from the world renowned company, Sheen. All types of paints are prepared to check the hiding power of Grounded Calcium Carbonate before it is sent to the customer.
Viscosity
White Carbonates has 480 Rotating Paddle Viscometer of Sheen for checking viscosity of Grounded Calcium Carbonate, slurry and paint. A good control on viscosity gives high stability to slurry, which ultimately gives stable viscosity in paint.
Opacity
Oil Absorption
Oil absorption of pigments and fillers is checked to find out the required demand of PVA in paint and PVC. It is tested using ASTM standard testing method for oil absorption of pigments by spatula rub-out.
