Abstract

DC60 (29/08/45) Slurry current modifiers contain low molecular weight compounds that Soluble in water. Type one [referred to hereinafter as compound (A)] and weight compound. The second type of water-soluble low molecule. [Referred to later in Here is compound (B)), different from this compound (A), where the viscosity of the actuase solution at 20 ° C was prepared by mixing the SA ( With a viscosity at 20 ° C equal to 100 mPa s or less) of compound (A) with a SB actuase solution (with a 20 ° C viscosity equal to 100 mPa s). At a rate equal to 50/50 by that weight, at least it can be at least twice the viscosity of any one of the alkaline solvents before it is treated. Mixed with slurry flow modifiers, which contain low molecular weight compounds that Soluble in water, type one (hereinafter referred to as compound (A)) and weight compound. The second type of water-soluble low molecule. (Referred to further in Here is compound (B)), unlike compound (A), where the viscosity of the actuase solution at 20 ํ is prepared by mixing the actuase solution Sa (with The viscosity at 20 ํ 100 mPa s or less) of compound (A) with aqueous Sb solution (with the viscosity at 20 ํ 100 mPa s). At a rate of 50/50 by that weight, at a minimum, it can be at least twice the viscosity of any one of the alkaline solvents before it is mixed.
