Increased ultimate tensile strength and elongation were obtained for PU + CaCO 3 nanocomposites with silane pre-treated filler. This can be explained as the consequence of better stress transfer through the composite, observed on scanning electron micrographs, due to an improved adhesion between PU matrix and silane-treated fillers.

01-01-2013  For calcium carbonate treated with polyphosphoric acid, an increase of glycerol contact angle is also observed, but the value is lower than the angle measured for the silane grafting. The higher polarity compared to silane treatment is probably due to the residual phosphoric acid functions present on the surface. A non polar liquid was also used.

Calcium carbonate - Wikipedia

Calcium carbonate is a chemical compound with the formula Ca CO 3.It is a common substance found in rocks as the minerals calcite and aragonite (most notably as limestone, which is a type of sedimentary rock consisting mainly of calcite) and is the main component of eggshells, snail shells, seashells and pearls.Calcium carbonate is the active ingredient in agricultural lime and is created when ...

(345f) Adsorption Behaviour of a Calcium Carbonate ...

When hard water is heated, the scale (deposit) of calcium carbonate builds up due to the decrease of solubility in heat-transfer devices like heat exchangers and evaporaters. This phenomenon is called fouling. The scale of calcium carbonate forms the low heat transfer layers on walls of heat exchangers. It causes heat transfer reduction.
