Interaction of anhydrite and melamine–formaldehyde polycondensates in aqueous suspensions
Source abstract
Abstract
Abstract The interactions of molecules of melamine–formaldehyde (MF) polycondensates in aqueous suspensions with synthetic anhydrite were studied. The sorption is selective. The medium molar fractions of additives are preferably sorbed on the surface of anhydrite and its product of hydration after 10 and 30 min of interaction. After 180 min, all high molar fractions are sorbed out. The results indicate that molecules of polycondensate tested interact with calcium ions in suspension and have a tendency to transform from R-SO 3 Na to R-(SO 3 ) 2 Ca form. Any other changes in the structure of molecules after interaction in aqueous suspension of anhydrite were not proved by the tests carried out.
