Improving the efficiency of diatomite in the finishing compositions
Abstract: The results of studies of regularities of structure formation of lime composites using diatomite. We consider the heat treatment and activation of diatomite addition of substances that increase the content of silica. It is shown that the effect of the temperature factor has led to a change in the energy state of the material surface, manifested in a change in the distribution of adsorption centers, marked a shift in the spectrum of CAR. An increase in the number of Bronsted acid sites on the surface of heat-treated diatomite compared to unfired diatomite. When you modify the silica sol diatomite revealed an increase in hydrophilicity of the surface, increasing the hydraulic activity. It is shown that the use of lime in the recipe formulations thermally activated and modified diatomite improves performance properties of composites.
Keywords: lime composites, activation, diatomaceous earth, the structure.
