METHOD AND SYSTEM FOR COMBINED MEASUREMENTS OF PHYSICOCHEMICAL PROPERTIES OF A PRODUCT ON POROUS MATERIAL

摘要

The present invention relates to a method and an additive preselection system for an aqueous composition intended to be in contact with a porous material (2). According to the method, the following steps are carried out: from the profile of a drop of aqueous solution comprising said additive placed on a sample of said porous material, at least the volume of said drop is determined, this volume determination is repeated; of the drop in time, - it is established from the evolution of the volume over time, the imbibition capacity of the solution in the material.
