Water suspensions with low viscosity and high solid content, including calcium carbonate, exhibit enhanced sensing stability at enhanced temperatures.

摘要

Water suspension enhances the repetition stability when the temperature rises.Including a material containing calcium carbonateAt least one polymer comb,The specific viscosities of at least one polymer measured at 25 g/l of polymer concentration at 20 C are different from those measured at 70 C. The specific viscosities differ from those measured at DHS.The absolute value of DHS varies from 0.15 to 0.5.At least one polymer comb has no barrier point between 20 and 95 degrees Celsius measured in water.At least one comb polymer has a specific load ranging from - 10 C/G to - 600 C/G to pH 8.The viscosity of hydrolytic suspension was 25-1000 MPa measured at 20 C and 90 C.
