Aqueous suspensions of materials comprising calcium carbonate with low deposit formation

摘要

Use of at least one anionically charged comb polymer as an agent against deposition in an aqueous suspension comprising a material containing calcium carbonate; wherein at least one anionically charged comb polymer has a specific charge of from -10 C / g to -250 C / g at pH 8; and wherein the electrical conductivity of the suspension comprising the at least one anionically charged comb polymer is less than 500 μS / cm at 25 ° C
