Title (EN) PROCESS OF PREPARING A WATER DISPERSIBLE HYDROPHOBIC OR AEROPHILIC SOLID
(FR) PROCEDE DE PREPARATION D'UN SOLIDE HYDROPHOBE OU AEROPHILE DISPERSIBLE DANS L'EAU
Abstract:
(EN) Process of preparing a hydrophobic/aerophilic solid which can be dispersed in water in the form of discrete microparticles, wherein the solid is milled in an aqueous medium in the presence of a hydrocolloid to obtain a suspension containing suspended particles of an average particle size not exceeding 10 $g(m)m and finely dividing and drying the suspension to obtain a powder.
(FR) Le procédé décrit, qui sert à préparer un solide hydrophobe-aérophile qui peut se disperser dans l'eau sous la forme de micro-particules séparées, consiste à broyer le solide dans un milieu aqueux en présence d'un hydrocolloïde en vue d'obtenir une suspension contenant des particules suspendues d'une granulométrie moyenne ne dépassant pas 10 $g(m)m, puis à séparer finement et à sécher la suspension en vue d'obtenir une poudre.
