u00b0 c u00b1 1 u00b0 c and 50 relative humidity u00b1 2 standards iso 187 1990 and tappi t402 sp 08 a cobb 60 measurement standards iso 535 1991 and tappi t441 om 04 is then performed which relates to the hydrophobicity of the paper the smaller the amount of water absorbed the more hydrophobic the paper table 3 for the handsheets made from the emulsions according to tests 12 to 16 a mean cobb value equal to 47 28 25 45 and 51 g m 2 is found respectively it is thus demonstrated that it is indeed the handsheets made according to the invention tests 13 and 14 which have the highest hydrophobicity the aim of this example is to illustrate the manufacture of an emulsion from asa and from an aqueous solution of cationic starchy material in a device according to the invention not containing a recirculation loop it notably demonstrates that the granulometric characteristics of the manufactured emulsions are constant over time the tests use the aqueous solution of cationic starchy material vector u00ae sca 2015 and the product chemsize u00ae a180 they are performed using a device identical to that described in the preceding example this example is performed under the same conditions as those of example 2 here the solids content was set at 8 the cationic starchy material asa dry ratio at 0 32 and the flow rate at the emulsification unit outlet at 220 l h and the peripheral speed at 40 m s 3 granulometric analyses are formed here on 3 samples collected at 45 minutes 3 hours and 5 hours besides the mean diameter d and the parameter lt 2 u03bcm the volume percentage of particles whose diameter.
