摘要： There is disclosed a method of preparing a concentrated aqueous suspension of a finely ground particulate material by a multistage grinding process in which an aqueous suspension of the particulate material is passed to and treated by grinding in each of a series of grinding stages, wherein a water soluble polycarboxylate dispersing agent for the particulate material is added to the suspension at each of a plurality of dispersion agent addition sites or stages. The invention is characterised in that the aqueous suspension when treated by grinding in at least one of the grinding stages has a pH on the inclusive range 8.5 to 9.8. Using the method described, suspensions can be prepared which are rheologically stable with time, and which contain a relatively high proportion by weight of a finely divided pigment.

摘要： A dispersion of a particulate inorganic material comprises a non-aqueous liquid medium containing a particulate inorganic material dispersed therein and an effective amount of one or more dispersing agent which serves to maintain the particulate inorganic material in dispersion in the non-aqueous medium, wherein the particulate inorganic material has an average particle size (d50) less than about 9 μm, the particulate inorganic material is present in the non-aqueous medium in an amount greater than about 70% by weight of the dispersion and the viscosity of the dispersion is less than about 150 Pa·s measured at room temperature on a Bohlin rheometer using a 20 mm cone/plate at a shear rate of 1/sec. A substantially dry particulate inorganic material surface treated with the dispersing agent and optionally one or more hydrophobising surface treatment agent, and capable of forming the said dispersion, is a further feature of the invention.
