WOA1
A process is provided for making a calcium carbonate slurry comprising the steps of (a) forming a mixture comprising water, an acidic dispersant system, and calcium carbonate, (b) grinding said mixture to form a preliminary slurry of particles of said calcium carbonate, wherein 50% or more by weight of said calcium carbonate in said preliminary slurry, based on the total weight .
TRIBOCHEMICALLY ACTIVATED NATURAL CHALK AS A FILLER FOR ...
ultrafine grinding was studied in surface modifiion of calcium carbonate particles by polymer grafting (Wua and Lu, 2003). In processing of plastics, chalks are most frequently used as fillers. Due to the relatively low adsorption of plasticisers and stabilisers on the chalk surface, the latter
Morphological control of calcium carbonate crystallized in ...
The influence of a surfactant over water on the polymorphism and crystal size of calcium carbonate produced by reaction crystallization in microemulsion systems was investigated in a mixing tank reactor. The crystallization was induced by the reaction between two aqueous micelle solutions (Na2CO3CaCl2) stabilized by anionic surfactants, SDS (sodium dodecyl sulfate) or .
Effect of ionic and anionic surfactants on the ...
Modifiion of calcium carbonate particles with surfactant significantly improves the properties of the calcium carbonate coating on paper. In this study, unmodified and CTAB (hexadecyltetramethylammonium bromide) and oleatemodified calcium carbonate nanoparticles were prepared using the wet carbonation technique for paper coating.
