The effect of soluble organic additives on the stress development during drying of calcium carbonate suspensions

Wedin, Par; Lewis , Jennifer A; Bergstrom , Lennart


The effect of polymer, plasticizer, and surfactant additives on stress development during drying of calcium carbonate particulate coatings was studied using a controlled-environment apparatus that simultaneously monitors drying stress, weight loss, and relative humidity. We found that the calcium carbonate coatings display a drying stress evolution typical of granular films, which is characterized by a sharp capillary-induced stress rise followed by a rapid stress relaxation. The addition of a...[Show more]
