WATER SUSPENSION WITH HIGH CONTENT OF SOLID PARTICLES OF INORGANIC SUBSTANCE, AND / OR FILLER, AND / OR PIGMENT IN A MEDIUM WITH ACID pH

摘要

1. An aqueous suspension with a high solids content of an inorganic substance and / or filler and / or pigment in an acidic pH medium that includes: a) at least one calcium carbonate-containing substance comprising calcium carbonate particles, and b) at least one salt of at least one strong acid, where at least one strong acid that forms at least one salt of at least one strong acid is selected from the group consisting of acids that have a pK value of less than or equal to zero at + 23 ° C, where the suspension with a high solids content has i) a solids content of at least 50% of the mass. of the total mass of an aqueous suspension with a high solids content, ii) Brookfield viscosity at 100 rpm ≤1000 mPa · s at -5 ° C, iii) pH 6 at + 23 ° C and iv) electrical conductivity between 10 and 100 mS / cm at -5 ° C and at + 23 ° C. 2. An aqueous suspension with a high solids content of the inorganic substance and / or filler and / or pigment according to claim 1, wherein the calcium carbonate particles of at least one calcium carbonate-containing substance are selected from natural calcium carbonate, precipitated calcium carbonate, or mixtures thereof. 3. An aqueous suspension with a high solids content of an inorganic substance and / or filler and / or pigment according to claim 1 or 2, wherein the particles of calcium carbonate containing at least one substance containing calcium carbonate have a weight average particle size of d from 0.1 to 50 μm preferably 0.25 to 50 microns, more preferably 0.3 to 5 microns and most preferably 0.4 to 3 microns. 4. An aqueous suspension with a high solids content of the inorganic substance and / or filler and / or pigment according to claim 1, where
