To be rapidly dissolved in water of the gels of water-soluble polymers by extrusion, tronconnage and placed in suspension in the application of shearing forces which are powerful

摘要

P & this method aims to obtain a fast dissolution in water of a water-soluble polymer gel, the to prepare an aqueous solution of this polymer diluted. / p & & p & the process according to the invention consists in extruding the gel10, cutting the strands obtenus49 and is put in suspension in the eau34 the particles obtained by means of the tronconnage. The suspension is then subjected to strong forces of cisaillement58, 60, 62 in order to form a suspension of very fine particles. This suspension is mixed has a supplement of water in the conditions of low shear, in order to form the aqueous solution of the polymer diluted. / p & & p & this reduces the degradation of certain properties of the polymer which is produced in the art. / p
