The influence of plasticizing additives on the basis of oxyphenol oligomer on rheological properties of cement mixes with a specific surface 354 sq.m/kg, at the constant water cement relation equal 0,3 were studied on PTs-500-D0 pastes of the Belgorod cement works.
The softeners which were received on the basis of oxyphenol oligomers are systematized and presented in Softeners on the basis of one-nuclear phenols (C[??]-1, C[??]-[PSI]) were produced in the polycondensation way: sulfate work (for introduction of hydrophilic groups), polycondensation with formaldehyde in the sour medium (environment) (for receiving oligomer molecules) and neutralization:
The influence of oxyphenol oligomer electrolytes on aggregate stability of suspensions was estimated on the most probable radius of the particles formed in the model systems by means of the sedimentation analysis.
Molecules of additives on the basis of oxyphenol oligomer are adsorbed on the surface of particles, forming a monomolecular layer.
The study conducted proved the possibility of the use of oxyphenol oligomer for water mineral suspensions as the effective plasticizing additives which were not worse than well- known C-3 flux oil being applied in construction now.
Adsorption of oxyphenol and furfurol oligomer on disperse materials/VA.
Colloidal and chemical aspects of plasticization of mineral suspensions by oxyphenol and furfurol oligomer/A.A.
Though I was bowled over in reading Dmitri Borgmann's LANGUAGE ON VACATION to find that "xylophone" has an anagram ("oxyphenol
"), there were a few of my favorites which did not appear.
