Comparative cement paste deflocculant studies show (Hommer, Wutz 2005), that suspension without deflocculant hy-dration induction period lasts about 30 minutes (later to begin a massive hydrate deposition), and the suspensions deflocculant induction period lasts about 2-3 hours, depending on the side chain length.
It is evident that kaolin suspensions without deflocculant typically exhibit shear-thinning behavior whereas well deflocculated systems show a rheological behavior close to Newtonian.
Based on these results, deflocculant concentrations of 0.
As the ceramic powder was disaggregated with ultrasound and their re-agglomeration avoided with an electrosteric deflocculant, it was assumed that all particles were single, nonporous and did not absorb water.
Further, it is used as a deflocculant with the addition of sodium silicate in the preparation of slip casting.
Excellent deflocculant in Low Solids Non-Dispersed Muds or Inhibitive Lime Muds; improves fluid loss control by improving clay platelet orientation.
Sometimes this would resolve itself after a day's standing and also I had often to adjust the deflocculants significantly and allow them to re-adjust with time.
Zeta potential instruments provide better knowledge of the interparticle forces in the colloid, allowing product developers to alter pH, add deflocculants or otherwise fine-tune their products for better stability.
To maintain the appropriate mud viscosity, deflocculants such as chrome-lignosulfonate are often used.
Chromium enters the mud from the chrome-based deflocculants and from naturally occurring minerals in the formation.
