Abstract

"PROCESSO PARA A PREPARAçãO DE PARTìCULAS DISCRETAS DE CARBONATO DE CáLCIO, E, COMPOSIçãO". Um produto e um processo para a preparação de partículas discretas de carbonato de cálcio que resulta da preparação de uma suspensão aquosa de carbonato de cálcio contendo carboidratos, a carbonatação da suspensão aquosa de carbonato de cálcio enquanto se mantém a temperatura escolhida de início da carbonatação. O produto da invenção presente é de partículas discretas de carbonato de cálcio que são particularmente úteis em tintas, plásticos, revestimento de papel, carga de papel, e em função do nível de pureza das partículas de carbonato de cálcio, pode ser utilizado em aplicações de cosméticos, produtos farmacêuticos e alimentos."PROCESS FOR THE PREPARATION OF DISCREET CALCIUM CARBONATE PARTICLES, AND, COMPOSITION". A product and a process for the preparation of discrete particles of calcium carbonate resulting from the preparation of an aqueous suspension of calcium carbonate containing carbohydrates, the carbonation of the aqueous suspension of calcium carbonate while maintaining the chosen temperature of onset of carbonation. The product of the present invention is of discrete calcium carbonate particles which are particularly useful in paints, plastics, paper coating, paper filler, and depending on the level of purity of the calcium carbonate particles, it can be used in applications of cosmetics, pharmaceuticals and food.
