Characteristics of the Treated Ground Calcium Carbonate

Fatty acid, surfactant, resin etc. are often used as surface modifying agents for calcium carbonate. An examination of the powder properties of a surface-modified filler is a very important factor in their effective use. Therefore, this study compared the surface properties, such as contact angle, hydrophobicity and dispersive component, as

Enhancement of the enzymatic hydrolysis of fines from

2015-10-5  Calcium carbonate which occurs as a filler in waste paper shows high adsorption affinity to the cellulase enzymes and thus reduces the available enzyme for cellulolysis. This can be remedied by the application of surfactants which preferentially occlude to the mineral surfaces and thus increase enzyme availability in solution.
